-/// This module provides a generic trading engine implementation for a market. On a high level, its a data structure,
-/// that stores an order book and provides APIs to place orders, cancel orders, and match orders. The market also acts
-/// as a wrapper around the order book and pluggable clearinghouse implementation.
-/// A clearing house implementation is expected to implement the following APIs
-///  - settle_trade(taker, maker, taker_order_id, maker_order_id, fill_id, is_taker_long, price, size): SettleTradeResult ->
-/// Called by the market when there is an match between taker and maker. The clearinghouse is expected to settle the trade
-/// and return the result. Please note that the clearing house settlment size might not be the same as the order match size and
-/// the settlement might also fail. The fill_id is an incremental counter for matched orders and can be used to track specific fills
-///  - validate_order_placement(account, is_taker, is_long, price, size): bool -> Called by the market to validate
-///  an order when its placed. The clearinghouse is expected to validate the order and return true if the order is valid.
-///  Checkout clearinghouse_test as an example of the simplest form of clearing house implementation that just tracks
-///  the position size of the user and does not do any validation.
-///
-/// - place_maker_order(account, order_id, is_bid, price, size, metadata) -> Called by the market before placing the
-/// maker order in the order book. The clearinghouse can use this to track pending orders in the order book and perform
-/// any other book keeping operations.
-///
-/// - cleanup_order(account, order_id, is_bid, remaining_size) -> Called by the market when an order is cancelled or fully filled
-/// The clearinhouse can perform any cleanup operations like removing the order from the pending orders list. For every order placement
-/// that passes the validate_order_placement check,
-/// the market guarantees that the cleanup_order API will be called once and only once with the remaining size of the order.
-///
-/// - decrease_order_size(account, order_id, is_bid, price, size) -> Called by the market when a maker order is decreased
-/// in size by the user. Please note that this API will only be called after place_maker_order is called and the order is
-/// already in the order book. Size in this case is the remaining size of the order after the decrease.
-///
-/// Following are some valid sequence of API calls that the market makes to the clearinghouse:
-/// 1. validate_order_placement(10)
-/// 2. settle_trade(2)
-/// 3. settle_trade(3)
-/// 4. place_maker_order(5)
-/// 5. decrease_order_size(2)
-/// 6. decrease_order_size(1)
-/// 7. cleanup_order(2)
-/// or
-/// 1. validate_order_placement(10)
-/// 2. cleanup_order(10)
-///
-/// Upon placement of an order, the market generates an order id and emits an event with the order details - the order id
-/// is a unique id for the order that can be used to later get the status of the order or cancel the order.
-///
-/// Market also supports various conditions for order matching like Good Till Cancelled (GTC), Post Only, Immediate or Cancel (IOC).
-/// GTC orders are orders that are valid until they are cancelled or filled. Post Only orders are orders that are valid only if they are not
-/// taker orders. IOC orders are orders that are valid only if they are taker orders.
-///
-/// In addition, the market also supports trigger conditions for orders. An order with trigger condition is not put
-/// on the order book until its trigger conditions are met. Following trigger conditions are supported:
-/// TakeProfit(price): If its a buy order its triggered when the market price is greater than or equal to the price. If
-/// its a sell order its triggered when the market price is less than or equal to the price.
-/// StopLoss(price): If its a buy order its triggered when the market price is less than or equal to the price. If its
-/// a sell order its triggered when the market price is greater than or equal to the price.
-/// TimeBased(time): The order is triggered when the current time is greater than or equal to the time.

-/// This module provides a core order book functionality for a trading system. On a high level, it has three major
-/// components
-/// 1. ActiveOrderBook: This is the main order book that keeps track of active orders and their states. The active order
-/// book is backed by a BigOrderedMap, which is a data structure that allows for efficient insertion, deletion, and matching of the order
-/// The orders are matched based on time-price priority.
-/// 2. PendingOrderBookIndex: This keeps track of pending orders. The pending orders are those that are not active yet. Three
-/// types of pending orders are supported.
-///  - Price move up - Trigggered when the price moves above a certain price level
-/// - Price move down - Triggered when the price moves below a certain price level
-/// - Time based - Triggered when a certain time has passed
-/// 3. Orders: This is a BigOrderMap of order id to order details.

+
+## 1. Introduction
+
+Movement Confidential Assets is an on-chain protocol that enables private fungible token transfers on the Movement blockchain. While transaction senders and recipients remain visible, **transfer amounts are hidden** using homomorphic encryption and zero-knowledge proofs.
+
+The protocol builds on the Aptos Confidential Asset framework, which was originally released under the Apache 2.0 open-source license. In November 2025, Aptos Labs changed the license on their `aptos-core` repository to a more restrictive license, and subsequently introduced proprietary changes to their confidential asset module (v1.1) under the new terms. Movement's implementation uses only code that predates the license change, and all production-hardening modifications are clean-room implementations based on published, public-domain cryptography — no post-license-change Aptos code was used or referenced. These modifications include chain ID binding to prevent cross-chain proof replay, SHA3-512 tagged hashing for Fiat-Shamir challenges, and a Schnorr-based registration proof to prevent key registration abuse.

+
+## 2. Protocol Overview
+
+### Lifecycle
+
+A user's interaction with confidential assets follows this lifecycle:
+
+```mermaid
+stateDiagram-v2
+    [*] --> Registered: register(ek, registration_proof)
+    Registered --> Funded: deposit(amount)
+    Funded --> Funded: transfer(proof)
+    Funded --> Funded: normalize(proof)
+    Funded --> Funded: deposit(amount)
+    Funded --> Withdrawn: withdraw(amount, proof)
+    Withdrawn --> Funded: deposit(amount)
+    Funded --> Rotating: rollover_and_freeze()
+    Rotating --> Funded: rotate_key(new_ek, proof) + unfreeze()
+```
+
+
+
+### Dual-Balance Architecture
+
+Each account maintains two encrypted balances to prevent front-running attacks:
+
+```mermaid
+flowchart TB
+    subgraph Account["Confidential Asset Store"]
+        PB[Pending Balance
4 chunks, 64-bit]
+        AB[Actual Balance
8 chunks, 128-bit]
+    end
+    D[Deposit / Incoming Transfer] --> PB
+    PB -- "rollover" --> AB
+    AB -- "withdraw / transfer" --> O[Outgoing]
+    style Account fill:#0f3460,color:#e0e0e0
+```
+
+
+
+- **Pending balance**: receives deposits and incoming transfers. Cannot be spent directly.
+- **Actual balance**: available for spending. Updated by rolling over the pending balance.
+
+This separation ensures that incoming transfers cannot interfere with in-progress proofs, since proofs are computed against the actual balance which is stable between rollovers.
+
+---
+
+## 3. Cryptographic Primitives
+
+### Twisted ElGamal Encryption
+
+Balances are encrypted using a twisted variant of ElGamal encryption over Ristretto255 [RFC 9496](https://www.rfc-editor.org/rfc/rfc9496).
+
+**Key generation:**
+
+$$dk \xleftarrow{R} \mathbb{Z}_q, \quad ek = dk^{-1} \cdot H$$
+
+where $H$ is a hash-to-point basepoint and $dk$ is the decryption key.
+
+**Encryption of value $v$ with randomness $r$:**
+
+$$C = v \cdot G + r \cdot H, \quad D = r \cdot ek$$
+
+**Homomorphic property:**
+
+$$\text{Enc}(v_1, r_1) + \text{Enc}(v_2, r_2) = \text{Enc}(v_1 + v_2, r_1 + r_2)$$
+
+This allows the blockchain to update encrypted balances without decryption.
+
+```mermaid
+flowchart LR
+    subgraph Encryption
+        V["value v"] --> C["C = v*G + r*H"]
+        R["randomness r"] --> C
+        R --> D["D = r*ek"]
+    end
+    subgraph Decryption
+        C2["C"] --> V2["v*G = C - dk*D"]
+        D2["D"] --> V2
+        V2 --> DLP["Solve DLP for v"]
+    end
+```
+
+
+
+### Bulletproofs Range Proofs
+
+Range proofs ensure that encrypted values lie within valid bounds, preventing overflow/underflow attacks. The protocol uses batch Bulletproofs verification [Bunz et al., 2018](https://eprint.iacr.org/2017/1066) to prove that each 16-bit chunk of a balance is in range $[0, 2^{16})$.
+
+### Ristretto255
+
+All elliptic curve operations use the Ristretto255 group [RFC 9496](https://www.rfc-editor.org/rfc/rfc9496), which provides a prime-order group suitable for cryptographic protocols, built on top of Curve25519.
+
+---
+
+## 4. Balance Representation
+
+### Chunked Encoding
+
+Balances are split into fixed-width chunks to enable efficient range proofs and bounded-complexity decryption:
+
+
+| Balance Type | Chunks | Bits per Chunk | Total Capacity |
+| ------------ | ------ | -------------- | -------------- |
+| Pending      | 4      | 16             | 64-bit         |
+| Actual       | 8      | 16             | 128-bit        |
+
+
+A balance value $b$ is decomposed as:
+
+$$b = \sum_{i=0}^{n-1} a_i \cdot 2^{16i}$$
+
+Each chunk $a_i$ is independently encrypted as a twisted ElGamal ciphertext $(C_i, D_i)$.
+
+```mermaid
+flowchart LR
+    subgraph "128-bit Actual Balance"
+        C0["Chunk 0
bits [0,16)"]
+        C1["Chunk 1
bits [16,32)"]
+        C2["Chunk 2
bits [32,48)"]
+        C3["..."]
+        C7["Chunk 7
bits [112,128)"]
+    end
+    C0 --> E0["(C₀, D₀)"]
+    C1 --> E1["(C₁, D₁)"]
+    C2 --> E2["(C₂, D₂)"]
+    C7 --> E7["(C₇, D₇)"]
+```
+
+
+
+### Normalization
+
+After multiple deposits, chunk values may exceed 16 bits due to homomorphic addition. **Normalization** re-encodes the balance with fresh randomness so all chunks are within $[0, 2^{16})$, accompanied by a zero-knowledge proof that the re-encoded balance represents the same value.
+
+### Pending Counter
+
+A counter tracks incoming transfers to the pending balance. After $2^{16} - 2$ transfers, the user must roll over the pending balance to the actual balance. This bounds the discrete log search space during decryption.
+
+---
+
+## 5. Protocol Operations
+
+### Register
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant Chain as Movement Chain
+    User->>User: Generate keypair (dk, ek)
+    User->>User: Compute Schnorr proof of dk
+    User->>Chain: register(ek, proof_commitment, proof_response)
+    Chain->>Chain: Verify registration proof
+    Chain->>Chain: Create ConfidentialAssetStore with zero balances
+```
+
+
+
+The registration proof prevents an attacker from registering someone else's key or a maliciously crafted key.
+
+### Deposit
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant FA as Fungible Asset Store
+    participant CA as Confidential Asset Store
+    User->>FA: Debit public balance
+    FA->>CA: Add to pending balance (homomorphic)
+    CA->>CA: Increment pending counter
+```
+
+
+
+Deposits are public (amount visible on-chain) but become private after rollover into the actual balance.
+
+### Transfer
+
+```mermaid
+sequenceDiagram
+    participant Sender
+    participant Chain as Movement Chain
+    participant Recipient
+    Sender->>Sender: Compute sigma proof + range proofs
+    Sender->>Chain: transfer(encrypted_amounts, proof)
+    Chain->>Chain: Verify sigma proof (balance relation)
+    Chain->>Chain: Verify range proofs (no overflow)
+    Chain->>Chain: Deduct from sender actual balance
+    Chain->>Chain: Add to recipient pending balance
+    Note over Chain: Amount hidden from all observers
+    Note over Chain: Auditor can decrypt if configured
+```
+
+
+
+The transfer proof demonstrates:
+
+1. Sender's new balance = old balance - transfer amount
+2. Transfer amount encrypted under recipient's key matches sender's committed amount
+3. All new balance chunks are in range $[0, 2^{16})$
+
+### Withdraw
+
+The inverse of deposit: the user proves that their encrypted balance contains at least the withdrawal amount, and the difference is properly range-constrained.
+
+### Key Rotation
+
+```mermaid
+sequenceDiagram
+    participant User
+    participant Chain as Movement Chain
+    User->>Chain: rollover_pending_balance_and_freeze()
+    Note over Chain: Account frozen, no incoming transfers
+    User->>User: Re-encrypt balance under new key
+    User->>User: Compute rotation proof
+    User->>Chain: rotate_encryption_key(new_ek, new_balance, proof)
+    Chain->>Chain: Verify rotation proof
+    Chain->>Chain: Update stored encryption key
+    User->>Chain: unfreeze_token()
+```
+
+
+
+### End-to-End Example: Sending MOVE Privately
+
+This example walks through every on-chain step required for Alice to send MOVE tokens privately to Bob, from start to finish.
+
+```mermaid

+```

+**Summary of transactions:**
+
+
+| Step | Who   | Transaction                               | Privacy                                |
+| ---- | ----- | ----------------------------------------- | -------------------------------------- |
+| 1    | Alice | `register(MOVE, ek_A, proof)`             | Public (one-time setup)                |
+| 2    | Bob   | `register(MOVE, ek_B, proof)`             | Public (one-time setup)                |
+| 3    | Alice | `deposit(MOVE, 1000)`                     | Amount visible (entering private pool) |
+| 4    | Alice | `rollover_pending_balance(MOVE)`          | No amount revealed                     |
+| 5    | Alice | `confidential_transfer(MOVE, Bob, proof)` | **Amount hidden**                      |
+| 6    | Bob   | `rollover_pending_balance(MOVE)`          | No amount revealed                     |
+| 7    | Bob   | `normalize(MOVE, ...)`                    | No amount revealed (only if needed)    |
+| 8    | Bob   | `withdraw(MOVE, amount, proof)`           | Amount visible (leaving private pool)  |
+
+
+The deposit (step 3) and withdrawal (step 8) amounts are visible on-chain since they interact with public balances. The transfer (step 5) is the private operation — only the sender, recipient, and optional auditor can determine the amount.

+
+### Multi-Scalar Multiplication (MSM) Verification
+
+Instead of checking multiple separate equations, the verifier combines all relations into a single MSM check using challenge-derived $\gamma$ scalars:
+
+$$\sum_i \gamma_i \cdot X_i = \text{MSM}\left(P_j, s_j\right)$$
+
+where:
+
+- $X_i$ are commitment points from the proof
+- $\gamma_i$ are derived from the challenge $\rho$ via SHA3-512
+- $P_j$ are public points (bases, balance components, encryption keys)
+- $s_j$ are computed scalars combining response scalars, challenges, and public values
+
+This batching reduces verification to a single MSM, which is significantly faster than multiple individual scalar multiplications.

+## 7. Fiat-Shamir Construction
+
+### Tagged Hashing
+
+The protocol uses BIP-340-style tagged hashing [Wuille et al., 2020](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki) with SHA3-512 [NIST FIPS 202](https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.202.pdf):
+
+$$\text{taggedhash}(\text{tag}, \text{msg}) = \text{SHA3-512}\left(\text{SHA3-512}(\text{tag})  \text{SHA3-512}(\text{tag})  \text{msg}\right)$$
+
+The double tag hash prefix is precomputable and provides collision resistance between different protocol contexts.
+
+### Domain Separation
+
+Each operation uses a distinct domain separation tag (DST):
+
+
+| Operation     | DST                                              |
+| ------------- | ------------------------------------------------ |
+| Registration  | `"MovementConfidentialAsset/Registration"`       |
+| Withdrawal    | `"MovementConfidentialAsset/Withdrawal"`         |
+| Transfer      | `"MovementConfidentialAsset/Transfer"`           |
+| Normalization | `"MovementConfidentialAsset/Normalization"`      |
+| Rotation      | `"MovementConfidentialAsset/Rotation"`           |
+| Range Proofs  | `"AptosConfidentialAsset/BulletproofRangeProof"` |
+
+
+### Chain ID and Sender Binding
+
+Every Fiat-Shamir challenge includes the chain ID and sender address as prefix bytes:
+
+$$\rho = \text{taggedhash}\left(\text{DST},\ \text{chainid}  \text{sender}  \text{publicparams}  X_1  \cdots  X_n\right)$$
+
+This binding ensures:
+
+- A proof generated for Movement mainnet cannot be replayed on testnet (or vice versa)
+- A proof generated by one sender cannot be replayed by a different sender
+- Proofs are tied to the specific transaction context
+
+```mermaid
+flowchart LR
+    CID["chain_id (1 byte)"] --> MSG
+    SENDER["sender address (32 bytes)"] --> MSG
+    PARAMS["public parameters"] --> MSG
+    COMMITS["commitment points"] --> MSG
+    MSG["Challenge Input"] --> TH["tagged_hash(DST, msg)"]
+    TH --> RHO["Challenge scalar ρ"]
+```
+
+
+
+### Gamma Scalar Derivation
+
+For MSM batching, additional scalars $\gamma_i$ are derived from the challenge via SHA3-512:
+
+$$\gamma_i = \text{SHA3-512}(\rho  i)$$
+
+converted to a scalar via `new_scalar_uniform_from_64_bytes`.
+
+---
+
+## 8. Registration Proof
+
+### Motivation
+
+Without a registration proof, an attacker could register an arbitrary encryption key for a victim's account, causing funds sent to that account to be unrecoverable. The registration proof is a Schnorr zero-knowledge proof of knowledge (ZKPoK) proving that the registrant knows the decryption key corresponding to the registered encryption key.
+
+### Protocol
+
+Given keypair $(dk, ek)$ where $ek = dk^{-1} \cdot H$:
+
+```mermaid
+flowchart TB
+    subgraph "Prover (off-chain)"
+        K["k ← random scalar"]
+        R["R = k · H"]
+        E["e = tagged_hash('Registration', chain_id ‖ sender ‖ token ‖ ek ‖ R)"]
+        S["s = k - e · dk⁻¹"]
+        K --> R --> E --> S
+    end
+    subgraph "Verifier (on-chain)"
+        E2["Recompute e from public inputs"]
+        CHECK["Check: s · H + e · ek == R"]
+        E2 --> CHECK
+    end
+    S --> E2
+    R --> E2
+```
+
+
+
+**Verification equation:** $s \cdot H + e \cdot ek = R$
+
+**Correctness:** Substituting $s = k - e \cdot dk^{-1}$ and $ek = dk^{-1} \cdot H$:
+
+$$(k - e \cdot dk^{-1}) \cdot H + e \cdot dk^{-1} \cdot H = k \cdot H = R \quad \checkmark$$
+
+**Proof size:** 64 bytes (32-byte compressed point + 32-byte scalar).
+
+---
+
+## 9. Security Properties
+
+### Balance Privacy
+
+- Transfer amounts are hidden from all observers (validators, other users)
+- Only the sender, recipient, and optional auditors can decrypt the amount
+- Multiple transfers between the same parties do not leak cumulative information beyond what each party can individually compute
+
+### Proof Soundness
+
+- Sigma protocols prove algebraic relationships with negligible soundness error
+- Bulletproofs range proofs prevent overflow/underflow attacks (each chunk proven < $2^{16}$)
+- MSM batching via random $\gamma$ scalars preserves soundness with overwhelming probability
+
+### Replay Protection
+
+```mermaid

+| Attack                 | Mitigation                             |
+| ---------------------- | -------------------------------------- |
+| Cross-chain replay     | Chain ID in challenge input            |
+| Cross-sender replay    | Sender address in challenge input      |
+| Cross-operation replay | Operation-specific DST tags            |
+| Key registration abuse | Schnorr ZKPoK required at registration |
+| Front-running          | Pending/actual balance separation      |
+| Chunk overflow         | Normalization + range proofs           |
+
+
+### Decryption Complexity
+
+
+| Operation                | DLP Search Space                      |
+| ------------------------ | ------------------------------------- |
+| Pending chunk decryption | $2^{16} \times \text{pendingcounter}$ |
+| Actual chunk decryption  | $2^{16} \times 2^{16} = 2^{32}$       |
+
+
+The 16-bit chunking ensures decryption remains computationally feasible for the balance holder while remaining infeasible for attackers without the decryption key.

+
+### What Was Inherited (Apache 2.0 Licensed)
+
+The following components predate Aptos's November 2025 license change and are used under their original Apache 2.0 license:
+
+- Twisted ElGamal encryption scheme and chunked balance representation
+- Core sigma protocol verification structure (MSM equations, gamma batching)
+- Bulletproofs range proof integration
+- Ristretto255 curve operations (`aptos_std::ristretto255`)
+- Fungible asset integration patterns
+
+### What Movement Changed
+
+The following changes were made to the inherited pre-license-change codebase. The original Aptos code did not include chain ID binding or a registration proof; Aptos added these independently in their proprietary v1.1 update. Movement's implementations are structurally different clean-room designs.
+
+- **Hash function**: SHA2-512 replaced with SHA3-512 throughout Fiat-Shamir
+- **Tagged hashing**: BIP-340 double-tag construction added
+- **Chain ID binding**: All challenges now include chain_id and sender address (the inherited code had neither)
+- **Registration proof**: New Schnorr ZKPoK requirement for key registration (the inherited code had no registration proof)
+- **DST branding**: Tags changed from `"AptosConfidentialAsset/"` to `"MovementConfidentialAsset/"`
+
+**Note:** The Bulletproofs range proof DST (`"AptosConfidentialAsset/BulletproofRangeProof"`) is unchanged from the inherited code because range proofs are verified by the pre-existing `ristretto255_bulletproofs` native module, and changing the DST would require matching changes in the native layer.

+
+### Non-Infringement Statement
+
+1. **No sigma protocol framework adopted.** Aptos v1.1 introduced 10+ new Move modules (`sigma_protocol*.move`) implementing a generic homomorphism-based prover/verifier. Movement does not use any of these modules. Verification logic remains in `confidential_proof.move` using direct MSM equations.
+2. **Different hash function and construction.** Movement uses SHA3-512 (NIST FIPS 202) with BIP-340 tagged hashing. Aptos uses SHA2-512 with BCS-serialized input structs and a two-level derivation. These are structurally different constructions.
+3. **Pre-existing code base.** The proof verification structure (MSM equations, gamma batching, deserialization) predates Aptos's November 2025 license change. Movement's modifications add chain ID parameters and switch the hash function; they do not adopt any v1.1 architectural patterns.
+4. **Registration proof is standard Schnorr.** The discrete-log proof of knowledge ($s \cdot H + e \cdot ek = R$) is a textbook Schnorr protocol (1989/1991), not derived from Aptos's `sigma_protocol_registration.move`.
+5. **The `aptos_hash::sha3_512()` native function and `ristretto255::new_scalar_uniform_from_64_bytes()` are pre-existing framework primitives** available under the original Apache 2.0 license.

+# Start Movement localnet (indexer API + faucet without delegation), enable confidential-assets
+# feature flag 87 (BULLETPROOFS_BATCH_NATIVES) via mint.key, then publish AptosExperimental using the
+# account in .movement/config.yaml (see MOVEMENT_PROFILE / --named-addresses).
+#
+# From repo root:
+#   ./scripts/start-localnet-confidential-assets.sh
+#
+# Ports (not the same service):
+#   • 8080 — fullnode REST API (ledger), what `move run-script --url` uses. Your log line
+#            "REST API endpoint: http://127.0.0.1:8080" is this.
+#   • 8070 — localnet "ready server" only: a tiny HTTP endpoint the CLI runs so clients can wait
+#            until *all* configured services pass health checks (node + faucet + Docker indexer
+#            stack when using --with-indexer-api). It is NOT the blockchain API.
+#            The CLI prints: Readiness endpoint: http://127.0.0.1:8070/
+#   To wait only for the node REST API (8080), set:  WAIT_STRATEGY=node
+#
+# Environment:
+#   MOVEMENT      — movement CLI (default: movement)
+#   APTOS         — deprecated alias for MOVEMENT if MOVEMENT is unset
+#   REPO_ROOT     — repo root (default: parent of scripts/)
+#   APTOS_ROOT    — deprecated alias for REPO_ROOT
+#   APTOS_LOCALNET_TEST_DIR — localnet data dir (default: $REPO_ROOT/.movement/testnet)
+#   NODE_URL      — REST base for `move run-script` (default: http://127.0.0.1:8080; refreshed from
+#                   $TEST_DIR/0/node.yaml when that file appears)
+#   READY_URL     — ready-server URL (default: http://127.0.0.1:8070/) when WAIT_STRATEGY=ready.
+#   WAIT_STRATEGY — ready | node (default: ready). "node" polls only NODE_URL/v1 (validator up).
+#   NODE_WAIT_TIMEOUT_SECS — max poll time (default: 120). When everything is healthy, localnet
+#          usually becomes ready in ~20s; raise this if Docker is pulling images or disks are slow.
+#   SKIP_START=1  — skip starting localnet; only run the feature-flag transaction
+#   BACKGROUND=0  — run localnet in the foreground (blocks; run feature step separately)
+#   SKIP_DOCKER_CHECK=1 — skip `docker info` preflight (not recommended with --with-indexer-api)
+#   KEEP_LOCALNET — after success, keep localnet running (default: 1). Set to 0 to always stop on exit.
+#          On failure, localnet is always shut down if this script started it (no orphan stacks).
+#   NODE_REST_WAIT_SECS — after the ready server, max time to wait for NODE_URL/v1 (default: 90).
+#   CORE_RESOURCES_ADDRESS — on-chain @core_resources address (default: 0xa550c18). Genesis creates
+#          this account at a fixed address then rotates its auth key to mint.key, so it is NOT the
+#          same as the address the CLI derives from the public key alone. We fund both via faucet,
+#          and pass --sender-account here so move run-script pays fees from 0xa550c18.
+#   FAUCET_URL — passed to fund-with-faucet (default: http://127.0.0.1:8081)
+#   FAUCET_WAIT_TIMEOUT_SECS — max time to keep polling for a ready faucet (default: 180). The script
+#          does NOT sleep a fixed 180s: it polls GET $FAUCET_URL/ every POLL_INTERVAL_SECS until the
+#          response body is tap:ok (official tap health), then runs fund-with-faucet immediately.
+#          If tap:ok never appears within this budget, the script exits with an error.
+#   FAUCET_HTTP_MAX_TIME — per-request curl --max-time when probing the faucet (default: 5)
+#   FAUCET_AMOUNT — Octas to request (default: 10000000000)
+#   SKIP_FAUCET=1 — skip the pre-flight fund step (otherwise python3 is used once to derive the
+#          pubkey-based address for the second fund-with-faucet call)
+#   MOVE_RUN_SCRIPT_MAX_GAS — --max-gas for move run-script (default: 2000000). On-chain
+#          maximum_number_of_gas_units is capped (e.g. 2_000_000 in config/global-constants for
+#          production genesis); higher values fail with MAX_GAS_UNITS_EXCEEDS_MAX_GAS_UNITS_BOUND.
+#   MOVEMENT_PROFILE — profile in $REPO_ROOT/.movement/config.yaml used to sign move publish
+#          (default: default). The package is published with --named-addresses
+#          aptos_experimental=, not Move.toml's 0x7.
+#   EXPERIMENTAL_PACKAGE_DIR — AptosExperimental package (default: $REPO_ROOT/aptos-move/framework/aptos-experimental)
+#   SKIP_EXPERIMENTAL_PUBLISH=1 — skip aptos-experimental move publish after the feature-flag script
+#   MOVE_PUBLISH_MAX_GAS — --max-gas for move publish (default: same as MOVE_RUN_SCRIPT_MAX_GAS)

The label “hash-to-point” refers to *how $H$ is constructed* (deterministic encoding to the group), not to a different mathematical type. Here $dk \in \mathbb{Z}_q$ is the secret **decryption** scalar and $ek \in \mathbb{G}$ is the public **encryption** key (a curve point, stored on-chain as `CompressedPubkey`).

Equivalently $dk \cdot ek = H$ (scalar multiplication of the point $ek$ by $dk$). If you are used to writing **public = secret $\cdot$ generator**, the twist here is **public = secret$^{-1} \cdot H$** for this second base $H$.

+# Aptos Move — formal methods (`AptosFormal`)
+
+This directory holds **Lean 4** proofs for the Aptos framework, structured so **`AptosFormal.Std.*`**
+tracks **stdlib**-aligned primitives (`aptos-stdlib`, `move-stdlib`, …) and
+**`AptosFormal.Experimental.*`** tracks **package-specific** specs (e.g. confidential assets).
+
+| Path | Contents |
+| ---- | -------- |
+| [`lean/`](lean/) | Lake project root — see [`lean/README.md`](lean/README.md) for **prerequisites and build instructions** |
+| [`REGISTRATION_VERIFY_REVIEW.md`](REGISTRATION_VERIFY_REVIEW.md) | Auditor-facing review note for `verify_registration_proof` |
+| `../move-stdlib/tests/formal_goldens_*.move` | Curated Move stdlib tests (hash / BCS / vector) aligned with `AptosFormal.Std.MoveStdlibGoldens` |
+| `../aptos-experimental/tests/confidential_asset/formal_goldens_*.move` | Move golden tests for Ristretto group laws, Fiat–Shamir transcript bytes, and verification equation |
+| [`check_golden_consistency.sh`](check_golden_consistency.sh) | Script to verify Move and Lean golden bytes haven't drifted apart |
+
+## Quick start
+
+Requires [elan](https://github.com/leanprover/elan) (Lean version manager). The toolchain
+(Lean 4.24.0 + Mathlib 4.24.0) is pinned in `lean/lean-toolchain` and `lean/lakefile.lean`.
+
+```bash
+cd aptos-move/framework/formal/lean
+lake build
+```
+
+See [`lean/README.md`](lean/README.md) for full details on verifying no `sorry` exists, checking
+axioms, running companion Move golden tests, and editor setup.
+
+## Directory design
+
+The formal directory lives at `framework/formal/` (not inside `aptos-experimental/`) because
+`AptosFormal.Std.*` modules are **shared across the entire framework**, not specific to any one
+package.
+
+Add future formal trees alongside the same pattern, e.g. `AptosFormal.Framework.*` for
+`aptos-framework` modules, reusing `AptosFormal.Std.*` where Move calls into `aptos_std`.

+# Registration proof verification: what Lean claims vs how to review Move
+
+This note is for **engineers and auditors** working on
+`aptos_experimental::confidential_proof::verify_registration_proof` and the Lean `**AptosFormal`** project under
+`aptos-move/framework/formal/lean/` (Lake package root; shared `**AptosFormal.Std.*`** modules apply across the framework, not only `aptos-experimental`).
+
+**Scope.** The Lean files and this note are aligned with **the Move sources in this branch** (e.g. `aptos-move/framework/aptos-experimental/sources/...`).
+
+**Source of truth (intentional).** The object being reviewed and (eventually) refined against Lean is `**verify_registration_proof` as written in this repository’s Aptos Move**, specifically the implementation under  
+`aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move`  
+and the framework modules it calls (`ristretto255`, `twisted_elgamal`, `std::bcs`, etc. **as pinned by this tree**).  
+
+This is **not** a claim about **Move IR**, **bytecode**, a generic “Move semantics,” or another compiler version: any eventual formal link should be stated as refinement to **this source-level behavior** first; IR↔source compiler correctness would be an **additional**, separate obligation if you ever need it.
+
+**Aptos framework layout (this repository).** The verifier and its dependencies live in these Move sources (paths relative to repo root):

+
+Lean **narrows the statement**: “verification succeeds iff these parses succeed and this equation holds.” It does **not** prove that the **framework natives used in this branch** (e.g. tagged hash, `ristretto255`, `std::bcs`) match the IRTF Ristretto spec or any independent reference, unless you add a large crypto formalization or external proof.
+
+## 2. What “match the verifier’s math” still assumes externally
+
+To identify the Lean `Prop` with successful Move execution you must separately justify:
+
+1. **BCS** — `senderBcs`, `contractBcs`, `tokenBcs` are exactly `std::bcs::to_bytes(&address)` for the same `address` values **this branch’s** Move code uses. In Lean this is modeled by `AptosAddressBcs` + `mkRegistrationInputs` (name = “Aptos-style `address` + BCS”; still **this repo only**).
+2. **Pubkey wire format** — `ekBytes` matches `twisted_elgamal::pubkey_to_bytes(ek)` and `pubkey_to_point` is correct on that encoding.
+3. **Commitment bytes** — `commitmentRBytes` matches `ristretto255::compressed_point_to_bytes(r_compressed)` for the same `R`.
+4. **Response scalar** — `responseBytes` parses like `ristretto255::new_scalar_from_bytes` (canonical encoding, range, etc.).
+5. **Challenge** — `challengeScalarFromMsg` matches `new_scalar_from_tagged_hash(FIAT_SHAMIR_REGISTRATION_SIGMA_DST, msg)` including tagged SHA3-512 and reduction mod ℓ.
+6. **Curve API** — `hash_to_point_base`, `point_mul`, `point_add`, `point_decompress`, `point_equals` match the Ristretto implementation Move calls.
+
+The constant `RegistrationVerify.fiatShamirRegistrationDst` is the UTF-8 DST string; the oracle `challengeScalarFromMsg` is still responsible for combining DST + `msg` exactly as Move does.
+
+## 3. Pen-and-paper protocol sketch (worked templates you can copy)
+
+This is the **cryptographic story** reviewers use; it is **not** a machine-checked Lean proof.
+
+**Goal (high level).** Show the prover knows a nonzero scalar `**dk`** such that `**ek = dk^{-1} · H`**, where `**H = hash_to_point_base()`** (equivalently `**H = dk · ek**`). Sources: `confidential_proof.move` (`prove_registration` / `verify_registration_proof`) and `ristretto255_twisted_elgamal.move`.
+
+Below, **copy the indented `text` blocks** into your note; they are a first complete draft. Replace bracketed notes if your notation differs.
+
+**Fiat–Shamir (NIZK) [FS87].** The deployed verifier uses `**e := RO(DST ‖ msg)`** instead of a uniformly chosen `e`. Soundness in that setting is argued in the **random oracle model** (§3.5; see [PS00] for the formal treatment of Σ-protocols under Fiat–Shamir).
+
+---
+
+### 3.1 Setup
+
+```text
+Let (E, +) be the Ristretto255 group of prime order ℓ. Write scalar multiplication as u · P ∈ E for u ∈ ℤ/ℓℤ, P ∈ E.
+Let H ∈ E be the public point from hash_to_point_base().
+Let ek ∈ E be the published registration public key (decompressed from pubkey bytes).
+The prover’s witness is dk ∈ (ℤ/ℓℤ)* satisfying  H = dk · ek   (equivalently ek = dk^{-1} · H).
+The statement is membership of (H, ek) in the language L = { ∃ dk ≠ 0 : H = dk · ek }.
+```
+
+---
+
+### 3.2 Interactive protocol (commit → challenge → response)
+
+```text
+Common input: H, ek ∈ E.
+Prover witness: dk with H = dk · ek.
+
+1) Commit:    Prover picks k ← ℤ/ℓℤ uniformly, sends R := k · H ∈ E.
+
+2) Challenge: Verifier picks e ← ℤ/ℓℤ uniformly (interactive case).
+
+3) Response:  Prover sends s := k − e · dk^{-1}   (arithmetic in ℤ/ℓℤ).
+
+4) Verify:    Accept iff s · H + e · ek = R.
+```
+
+**Completeness (honest prover)** — paste and justify each `=`:
+
+```text
+Assume H = dk · ek. Then
+  s·H + e·ek
+    = (k − e·dk^{-1})·H + e·ek
+    = k·H − e·dk^{-1}·(dk·ek) + e·ek
+    = k·H − e·ek + e·ek
+    = k·H = R.
+```
+
+Use scalar laws on the curve: `(ab)·P = a·(b·P)`, `(u+v)·P = u·P + v·P`.
+
+**Move alignment (prover).** `point_mul(h, k)` is `k·H`; `scalar_sub(k, scalar_mul(e, dk_inv))` is `s = k − e·dk^{-1}`.
+
+---
+
+### 3.3 Special soundness (two challenges, same `R` → extract `dk`)
+
+**Lemma (template).** Two accepting transcripts `(R, e, s)` and `(R, e′, s′)` with `**e ≠ e′`** yield `**dk`** with `**H = dk · ek`**.
+
+**Proof (copy the algebra):**
+
+```text
+Suppose
+  s·H  + e·ek  = R,
+  s′·H + e′·ek = R.
+Subtract:
+  (s − s′)·H + (e − e′)·ek = 0
+  (s − s′)·H = (e′ − e)·ek.                    (∗)
+Substitute H = dk·ek:
+  (s − s′)·(dk·ek) = (e′ − e)·ek.
+For ek ≠ O in a prime-order group, cancel ek to scalars:
+  (s − s′)·dk = e′ − e,
+  dk = (e′ − e) · (s − s′)^{-1}   (when e ≠ e′ and s ≠ s′).
+```
+
+**One-line reduction:** A cheat who does not know such a `dk` cannot produce two distinct accepting `e` for the same fixed `R` without breaking **discrete logarithm** on `E` (or state your preferred explicit game).
+
+---
+
+### 3.4 Honest-verifier zero-knowledge (simulator)
+
+For **interactive** proofs with **uniform** `e`:
+
+```text
+Simulator S(H, ek, e):
+  s ← ℤ/ℓℤ uniform
+  R := s·H + e·ek
+  output (R, e, s).
+
+Then s·H + e·ek = R holds by construction.
+The distribution of (R, e, s) matches the real protocol when the verifier’s e is uniform (standard Schnorr HVZK proof).
+```
+
+For **Fiat–Shamir NIZK**, say explicitly that you use **ROM programming** (different proof template); do not claim interactive HVZK without that caveat.
+
+---
+
+### 3.5 Assumptions checklist (tick for your report)
+
+```text
+[ ] (E, +) is the Ristretto255 prime-order group; scalars are in ℤ/ℓℤ.
+[ ] Discrete logarithm (or ECDLP) is hard on E — special soundness reduces forging to breaking it.
+[ ] Interactive: challenge e uniform and independent of prover coins.
+[ ] NIZK: RO model for e = Hash(DST, msg); Fiat–Shamir security for Σ-protocols [FS87, PS00].
+[ ] Wire correctness: decompress/encode for H, ek, R and canonical scalar parsing for s, e.

+
+**One-line soundness story:** *Without `dk`, getting two different valid `e` for the same `R` contradicts special soundness / DLOG; with Fiat–Shamir, the RO makes `e` unpredictable after `R` is fixed.*
+
+## 4. How to review **production Move** (practical)
+
+Lean does not replace this.
+
+1. **Read the code path** — `verify_registration_proof` in `confidential_proof.move` (and callees in `ristretto255` / `twisted_elgamal`).
+2. **Unit tests** — `confidential_proof_tests.move` registration tests: honest proof verifies; wrong `ek`, token, chain, sender, contract fail.
+3. **Cross-check constants** — DST string, order ℓ in Lean `AptosFormal.Std.Crypto.Ristretto255` vs Ristretto / Curve25519 references.
+4. **Cross-check transcript** — `registrationFiatShamirMsg` field order vs `msg.append` order in Move.
+5. **External crypto references** — Ristretto group formulas, BIP-340-style tagging if applicable to `new_scalar_from_tagged_hash`, and how `std::bcs` encodes `address` **in the framework version pinned by this branch**.
+6. **Optional**: independent implementation (e.g. script) that recomputes `e` and the group check from the same byte inputs for golden test vectors (not required for Lean).
+
+## 5. Where to extend Lean next
+
+- Prove lemmas **assuming** group laws and an injective challenge map (already partly in `AptosFormal.Experimental.ConfidentialAsset.Registration.Formal`).
+- Refine `CryptoOracle` with **axioms** that state algebraic laws (e.g. associativity of `pointAdd`) and relate `challengeScalarFromMsg` to `fiatShamirRegistrationDst` concatenation.
+- A full proof chain to **concrete** framework natives (as compiled from **this** tree) is a **large** separate project; see **§6** for a structured list of what is still missing.
+
+---
+
+## 6. Remaining proof obligations (not covered by current Lean)
+
+This section records **everything that is not** machine-checked today, in one place. Completeness of the Schnorr equation and the ideal-oracle bridge are in `AptosFormal.Experimental.ConfidentialAsset.Registration.SchnorrCompleteness`; the items below are **still external** (review, tests, crypto argument, or a future formalization stack).
+
+### 6.1 Move VM semantics
+
+**Goal.** Show that executing `verify_registration_proof` **as defined in this repository’s Move sources** (see the framework table at the top of this doc) **implements** `verifyRegistrationProofProp` (or `verifyRegistrationProofPropMove`) up to the oracle: same **argument order**, same **control flow** on success vs abort. The refinement target is **that source**, not Move IR or bytecode unless you add a compiler-correctness story.
+
+**Current status.** `Operational.lean` defines `execVerifyRegistrationProof` (lines 22–38) which mirrors the Move function's control flow step-by-step. The structural correspondence is:
+
+
+| Move (`confidential_proof.move` lines 214–245)                                     | Lean (`Operational.lean` lines 24–36)                                |
+| ---------------------------------------------------------------------------------- | -------------------------------------------------------------------- |
+| 214–216: `new_compressed_point_from_bytes` / `assert` / `extract` → `r_compressed` | 25: `compressed32?` → `rComm`; 28: `C.pointDecompress rComm` → `rhs` |
+| 219–221: `new_scalar_from_bytes` / `assert` / `extract` → `s`                      | 24: `C.scalarFromBytes responseBytes` → `s`                          |
+| 223–230: Build `msg` + `new_scalar_from_tagged_hash` → `e`                         | 29: `C.challengeScalarFromMsg (registrationFiatShamirMsg i)` → `e`   |
+| 233: `hash_to_point_base()` → `h`                                                  | 31: `let H := C.hashToPointBase`                                     |
+| 235: `pubkey_to_point(ek)` → `ek_point`                                            | 26+29: `compressed32?` + `C.pubkeyToPoint ekComm` → `ek`             |
+| 236–239: `point_add(point_mul(h,s), point_mul(ek_point,e))` → `lhs`                | 32: `C.pointAdd (C.pointMul H s) (C.pointMul ek e)`                  |
+| 240: `point_decompress(&r_compressed)` → `rhs`                                     | 28: `C.pointDecompress rComm` → `rhs`                                |
+| 242–245: `assert!(point_equals(&lhs, &rhs))`                                       | 33–36: `if C.pointEqBool lhs rhs then some () else none`             |
+
+
+The theorem `execVerifyRegistrationProof_iff` proves this `Option`-returning function is equivalent to the `Prop`-valued `verifyRegistrationProofProp`.
+
+**Not proved in Lean:**
+
+- Operational semantics of Move (values, references, `assert!` / `abort`, `friend`, gas not-withstanding).
+- That `option::is_some` / `option::extract` on `new_compressed_point_from_bytes`, `new_scalar_from_bytes`, etc., match the `Option` branches in `verifyRegistrationProofProp` (success path vs `False`).
+- That `point_equals` in Move corresponds to `CryptoOracle.pointEq` (or `=` in the idealized bridge).
+
+**Review anchor.** `confidential_proof.move` — `verify_registration_proof` (decompress `R`, parse `s`, build `msg`, `new_scalar_from_tagged_hash`, base point `H`, `pubkey_to_point`, `point_add` / `point_mul`, final `assert!`).
+
+---

+### 6.2 Native correctness (`CryptoOracle` vs Move)

+
+**Move golden tests (§6.2 evidence).** `formal_goldens_ristretto.move` (8 passing tests) verifies group-law properties of the `ristretto255` natives on this branch: scalar identity (`1·H = H`), annihilation (`0·H = 0`), double-add consistency, distributivity, commutativity, identity element, and scalar multiplication associativity.
+
+**Review anchor.** `ristretto255` module, `ristretto255_twisted_elgamal.move`, `confidential_proof.move` (`new_scalar_from_tagged_hash` implementation).
+
+---
+
+### 6.3 BCS (`address` → transcript bytes)
+
+**Goal.** The bytes fed into `registrationFiatShamirMsg` for `sender`, `contract`, and `token` are **exactly** `std::bcs::to_bytes(&address)` for the same runtime `address` values Move uses, in the **framework version pinned by this branch**.
+
+**Lean model.** `AptosAddress32` + `aptosAddress32Bcs` / `mkRegistrationInputs32`: **32 raw bytes**, no outer length prefix, matching the usual Aptos `address` BCS layout used in this codebase’s Move sources.
+
+**Not proved in Lean:**
+
+- That real `std::bcs::to_bytes(&address)` is always 32 bytes and matches those 32 bytes field-for-field for every address the VM can pass into `verify_registration_proof`.
+- Any change to BCS rules or `address` representation in the framework invalidates a byte-level claim until re-audited.
+
+**Move golden tests (§6.3 evidence).** `formal_goldens_bcs_address.move` (7 passing tests) verifies BCS encoding of `address` values `@0x1`, `@0x2`, `@0x3`, `@0x10`, `@0x20`, `@0x30`, and `@0xFFF…F` as 32 raw bytes with no length prefix, matching the `AptosAddress32` model in Lean.
+
+**Review anchor.** Aptos Move `address` + `std::bcs` spec for the release you ship.
+
+---
+
+### 6.4 Cryptographic security (soundness / knowledge soundness)
+
+**What Lean proves today.**
+
+- **Completeness** of the Schnorr check for an honest prover (`registrationSchnorr_completeness`, `registrationVerifySpec_completeness` in `…Registration.SchnorrCompleteness`).
+- **Special soundness** (`registrationSchnorr_witness_extraction` in `…Registration.CryptoSecurity`): two accepting transcripts `(R, e₁, s₁)` and `(R, e₂, s₂)` with `e₁ ≠ e₂` yield an explicit witness `dk = (s₁ − s₂)⁻¹ · (e₂ − e₁)` with `H = dk · ek`. The proof uses `Field RistrettoScalar` (via the `Fact (Nat.Prime ℓ)` instance) for scalar inversion.
+- **HVZK simulator** (`registrationSchnorr_simulate` / `registrationSchnorr_simulate_accepts`): given `(H, ek, e, s)`, the simulator produces `R := s·H + e·ek` which is always an accepting transcript.
+
+**Not proved in Lean (pen-and-paper / ROM in §3):**
+
+- **Knowledge soundness** as a computational reduction (the witness extraction is algebraic; the computational game argument reducing a successful forger to DLOG is not formalized).
+- **Fiat–Shamir** — replacing uniform `e` by `e = Hash(DST, msg)` is sound in the **random oracle model** (standard result for Σ-protocols: Pointcheval–Stern [PS00] §7).
+- **Hardness** — discrete logarithm (or equivalent) on the Ristretto255 group.
+
+Lean does **not** formalize a random oracle, a computational game, or a reduction to DLOG.
+
+---
+
+### 6.5 Primality of ℓ (subgroup order)
+
+**Current status.** `ristretto_subgroup_order_prime : Nat.Prime ristrettoSubgroupOrder` is an `**axiom`** in `AptosFormal.Std.Crypto.Ristretto255` (spec constant from Ristretto / Curve25519 literature), not a **formal primality certificate** inside Lean. A `Fact (Nat.Prime ristrettoSubgroupOrder)` instance is derived from the axiom, making `Field RistrettoScalar` available everywhere (used by the special soundness proof in `CryptoSecurity.lean`).
+
+**To remove the axiom.** Supply a **Pratt primality certificate** for `ristrettoSubgroupOrder` and verify it in Lean. This requires:
+
+1. The complete factorization of `ℓ − 1` (obtainable from a computer algebra system like SageMath or PARI/GP).
+2. A primitive root `g` modulo `ℓ`.
+3. Recursive Pratt certificates for each prime factor of `ℓ − 1`.
+
+Trial division (`native_decide` on `Nat.Prime`) is infeasible for a 252-bit prime (≈ 2^126 trial divisions).
+
+**Review anchor.** Standard curve parameters [HDEVALENCE, Ber06] vs the numeric literal in `AptosFormal.Std.Crypto.Ristretto255`.

+### 6.6 Audit checklist (copy for reports)
+
+```text
+[ ] §6.1  VM: verify_registration_proof success/abort matches Option/False split in verifyRegistrationProofProp.
+[ ] §6.2  Natives: each CryptoOracle field matched to Move; SHA3/tagged hash vs `AptosFormal/Std/Hash/Sha3_512.lean` explicitly reviewed.
+[ ] §6.3  BCS: sender/contract/token bytes are to_bytes(&address) as in this framework version (32-byte model).
+[ ] §6.4  Crypto: soundness / FS / ROM / DLOG documented (§3 templates); not claimed as Lean theorems.
+[ ] §6.5  ℓ prime: accepted as axiom or replaced by a certificate proof in Lean.

+- The ROM argument replaces the real hash with a lazy random oracle, then shows

+# End-to-end registration verification — group axioms ↔ Schnorr equation

+Ties together every Lean module in the registration proof stack:
+
+1. **TranscriptAlignment** — FS message bytes match Move golden (`native_decide`).
+2. **VerifyMath** — `verifyRegistrationProofProp` reduces to the curve equation.
+3. **SchnorrCompleteness** — honest prover satisfies the equation.
+4. **GroupAxioms** — Move's `ristretto255` operations satisfy group laws (external).
+
+## Main results
+
+- `registration_verification_iff_schnorr` — for **any** inputs (under group axioms),
+  Move's `verify_registration_proof` succeeds iff `s·H + e·ek = R`.
+- `registration_honest_prover_accepted` — honest prover always passes.
+- `golden_challenge_exists` / `golden2_challenge_exists` — the challenge scalar is
+  well-defined for both golden scenarios.
+- `golden_registration_verification_iff_schnorr` — instantiation at golden inputs.
+- `registration_challenge_deterministic` — Fiat–Shamir challenge is unique.
+
+## Remaining external obligations
+
+See §6 of `REGISTRATION_VERIFY_REVIEW.md`:
+- §6.1 VM semantics (Move execution matches `verifyRegistrationProofProp`)
+- §6.2 Native correctness (`RistrettoGroupAxioms` holds for this branch's natives)
+- §6.3 BCS address encoding
+- §6.4 Cryptographic security (soundness / knowledge-soundness / Fiat–Shamir in ROM)

+# AptosFormal (Lean 4)
+
+Machine-checked definitions and proofs for **Aptos Move framework** behavior, structured for growth
+beyond a single package.
+
+| Prefix | Role |
+| ------ | ---- |
+| `AptosFormal.Std.Hash.*` | SHA3-512 tagged hash vs `aptos_std::aptos_hash` |
+| `AptosFormal.Std.Crypto.*` | Ristretto scalar / wire types vs `aptos_std::ristretto255` |
+| `AptosFormal.Std.Bcs.*` | BCS primitives |
+| `AptosFormal.Std.MoveStdlibGoldens` | Byte-level golden tests for hash/BCS/vector |
+| `AptosFormal.Experimental.ConfidentialAsset.Registration.*` | `verify_registration_proof` spec + proofs |
+
+Auditor-oriented narrative: [`../REGISTRATION_VERIFY_REVIEW.md`](../REGISTRATION_VERIFY_REVIEW.md).
+
+## Prerequisites
+
+| Dependency | Version | Notes |
+| ---------- | ------- | ----- |
+| [elan](https://github.com/leanprover/elan) | latest | Lean version manager (like `rustup` for Lean) |
+| Lean 4 | **4.24.0** | Pinned in `lean-toolchain`; `elan` installs it automatically |
+| [Mathlib](https://github.com/leanprover-community/mathlib4) | **v4.24.0** | Fetched by Lake on first build |
+
+Install `elan` (macOS/Linux):
+
+```bash
+curl https://elan.dev/install.sh -sSf | sh
+```
+
+## Building the proofs
+
+```bash
+cd aptos-move/framework/formal/lean
+lake build
+```
+
+**First build** downloads the Mathlib toolchain cache (~1 GB) and compiles all modules.
+Subsequent builds are incremental and fast.
+
+**Expected output on success:** no errors, no warnings (other than potential Mathlib `simp` linter
+notes which do not affect soundness). The build exits with code 0.
+
+## Verifying there are no `sorry`
+
+A `sorry` in Lean is an axiom that lets you skip a proof — it makes the entire file unsound.
+After building, check that none exist:
+
+```bash
+cd aptos-move/framework/formal/lean
+grep -r "sorry" AptosFormal/ --include="*.lean"
+```
+
+This should return **no matches**. (The word "sorry" may appear in comments explaining what
+*could* be sorry'd; `grep` for `sorry` outside comments if you want to be precise, or run
+`lake env printPaths` and inspect the `.olean` files for `sorryAx` usage.)
+
+You can also check what axioms any theorem depends on. Create a file `_check_axioms.lean`:
+
+```lean
+import AptosFormal.Experimental.ConfidentialAsset.Registration.EndToEnd
+import AptosFormal.Experimental.ConfidentialAsset.Registration.CryptoSecurity
+
+open AptosFormal.Experimental.ConfidentialAsset.Registration.EndToEnd
+open AptosFormal.Experimental.ConfidentialAsset.Registration.CryptoSecurity
+
+#print axioms registration_verification_iff_schnorr
+#print axioms registration_honest_prover_accepted
+#print axioms registrationSchnorr_witness_extraction
+#print axioms registrationSchnorr_simulate_accepts
+```
+
+Then run it:
+
+```bash
+lake env lean _check_axioms.lean
+```
+
+Expected output:
+
+```
+'...registration_verification_iff_schnorr' depends on axioms: [propext, Quot.sound]
+'...registration_honest_prover_accepted' depends on axioms: [propext, Quot.sound]
+'...registrationSchnorr_witness_extraction' depends on axioms: [propext, Classical.choice, Quot.sound, ...ristretto_subgroup_order_prime]
+'...registrationSchnorr_simulate_accepts' depends on axioms: [propext, Quot.sound]
+```
+
+| Axiom | What it is | Concern |
+|-------|-----------|---------|
+| `propext` | Propositional extensionality | Built-in; universally accepted |
+| `Quot.sound` | Quotient soundness | Built-in; universally accepted |
+| `Classical.choice` | Law of excluded middle | Standard classical logic; used by Mathlib |
+| `ristretto_subgroup_order_prime` | ℓ is prime | **Our only custom axiom** — see §6.5 of review doc |
+
+If you see `sorryAx` in the output, something is wrong — a proof has been bypassed.
+
+## Companion Move golden tests
+
+These Move test files provide empirical evidence for assumptions that Lean cannot check
+(native crypto operations, BCS encoding). Run them from the repo root:
+
+| Test file | What it checks | Run command |
+| --------- | -------------- | ----------- |
+| `move-stdlib/tests/formal_goldens_bcs.move` | BCS encoding of primitives | `aptos move test --package-dir aptos-move/framework/move-stdlib` |
+| `move-stdlib/tests/formal_goldens_hash.move` | SHA3-256/512 + keccak golden bytes | same as above |
+| `move-stdlib/tests/formal_goldens_vector.move` | Vector operations | same as above |
+| `move-stdlib/tests/formal_goldens_bcs_address.move` | BCS address → 32 raw bytes (§6.3) | same as above |
+| `aptos-experimental/tests/confidential_asset/formal_goldens_registration.move` | Fiat-Shamir transcript bytes | `aptos move test --package-dir aptos-move/framework/aptos-experimental` |
+| `aptos-experimental/tests/confidential_asset/formal_goldens_ristretto.move` | Ristretto group-law properties (§6.2) | same as above |
+| `aptos-experimental/tests/confidential_asset/formal_goldens_verification_equation.move` | Full verification equation: honest proof passes, corrupted/wrong-dk rejected (§6.1) | same as above |
+
+Run all formal golden tests at once:
+
+```bash
+aptos move test --package-dir aptos-move/framework/move-stdlib --filter formal_goldens
+aptos move test --package-dir aptos-move/framework/aptos-experimental --filter formal_goldens
+```
+
+## Checking Move / Lean golden consistency
+
+Golden byte constants (SHA3 digests, BCS addresses, FS transcript messages) are duplicated
+between Move test files and Lean source. A consistency check script verifies they haven't drifted:
+
+```bash
+bash aptos-move/framework/formal/check_golden_consistency.sh
+```

+# Symbolic Fiat–Shamir model for registration Schnorr
+
+Machine-checked proofs that the Fiat–Shamir transform of the registration
+Schnorr protocol inherits the interactive protocol's security properties
+under a symbolic (abstract function) hash model.
+
+## Results
+
+| Theorem | Property |
+|---------|----------|
+| `fiatShamir_forking_extraction` | Two oracle worlds → witness extraction |
+| `fiatShamir_forking_explicit` | Explicit extraction formula `dk = (s₁−s₂)⁻¹(e₂−e₁)` |
+| `fiatShamir_challenge_binding` | Fixed oracle → no forking possible |
+| `fiatShamir_completeness` | Honest NIZK prover always passes |
+| `fiatShamir_nizk_simulate_accepts` | Simulator produces valid proofs without witness |
+
+## What this captures
+
+The Fiat–Shamir transform replaces the verifier's random challenge with
+`e := taggedHash(fsMsg)`.  We model `taggedHash` as an abstract function
+`ByteArray → RistrettoScalar` and prove:
+
+- **Forking reduction**: if an adversary's proof passes under *two different*
+  hash functions that disagree on the FS message, the witness `dk` can be
+  extracted.  This is the algebraic core of the ROM forking lemma [PS00].
+- **Challenge binding**: for a *single* hash function, two proofs with the
+  same commitment `R` must share the same challenge — so forking requires
+  oracle reprogramming.
+- **Completeness** and **NIZK zero-knowledge** (simulation with programmed oracle).
+
+## Remaining gap
+
+The **probability** that an adversary triggers the forking condition is not
+formalized.  In [PS00], this is shown via a rewinding argument over a random
+oracle; formalizing it requires a probability monad or game-based framework
+and is out of scope.
+
+## Connection to Move
+
+`fiatShamirVerify` is the abstract form of the Schnorr equation `s•H + e•ek = R`
+on the RHS of `registration_verification_iff_schnorr` in `EndToEnd.lean`.  The
+symbolic security theorems here apply to `verifyRegistrationProofProp` via that
+bridge: every `verifyRegistrationProofProp` instance that passes also satisfies
+`fiatShamirVerify` (with `e = taggedHash(fsMsg)`, `H = hashToPointBase`).

+# aptos-experimental
+
+Move packages that are **experimental**: APIs may change. The largest surface area here is **Confidential Assets** — private fungible balances with homomorphic encryption and on-chain zero-knowledge verification.
+
+## Confidential Assets — where to read
+
+| Document | Purpose |
+| -------- | ------- |
+| [`whitepaper.md`](./whitepaper.md) | End-to-end protocol, Fiat–Shamir, security discussion, and **full `Transferred` event field reference** (§5). |
+| [`doc/`](./doc/) | Generated Move API reference (`confidential_asset`, `confidential_proof`, `confidential_balance`, …). |
+| [`sources/confidential_asset/`](./sources/confidential_asset/) | Modules: `confidential_asset`, `confidential_proof`, `confidential_balance`, `ristretto255_twisted_elgamal`, gas e2e helpers (`#[test_only]`). |
+| [`tests/confidential_asset/`](./tests/confidential_asset/) | Move unit tests (`confidential_asset_tests`, `confidential_proof_tests`). |
+
+Rust **`e2e-move-tests`** (repo root `aptos-move/e2e-move-tests`) calls into `confidential_gas_e2e_helpers` to pack proofs for real transactions; they complement but do not replace Move tests for event shape.
+
+## `Transferred` event (indexers & integrators)
+
+Emitted on each successful **`confidential_transfer`**. There is **no cleartext amount** in the payload; observers still see cryptographic material suitable for correlation and auditor workflows.
+
+| Field | Summary |
+| ----- | ------- |
+| **`from`**, **`to`**, **`asset_type`** | Sender and recipient addresses; **`asset_type`** is the FA metadata object address for the token. |
+| **`amount`** | Compressed ciphertext for the transferred amount (recipient key, pending-balance layout). |
+| **`ek_volun_auds`** | Flattened **`sigma_proof.xs.x7s`**: per auditor row in the proof, **four** compressed Ristretto points (32 bytes each), row-major order. Length **`128 × n`** bytes (`n` = auditor rows; **`n = 0`** ⇒ empty `vector`). Produced by `confidential_proof::transfer_proof_ek_volun_auds_flat_bytes`. |
+| **`sender_auditor_hint`** | Opaque bytes (≤ **256**); must be identical when proving and when submitting the entry; bound into the transfer sigma Fiat–Shamir hash (BCS). |
+| **`new_sender_available_balance`**, **`new_recip_pending_balance`** | Sender’s new **actual** balance and recipient’s new **pending** balance (compressed ciphertexts). |
+| **`memo`** | Reserved; **empty** `vector` in the current implementation. |
+
+**Integrator rule:** whatever bytes you pass as **`sender_auditor_hint`** to the on-chain entry must be the same bytes you included when generating the transfer proof (Fiat–Shamir binds them).
+
+**Test coverage:** `confidential_asset_tests` uses `assert_last_transferred_event_matches_state` to check addresses, `asset_type`, hint, `ek_volun_auds` **length** vs auditor count, and both post-transfer ciphertexts against on-chain store. `confidential_proof_tests` cover proof verification (including wrong-hint failure) without going through the event path.

 Movement Confidential Assets is an on-chain protocol that enables private fungible token transfers on the Movement blockchain. While transaction senders and recipients remain visible, **transfer amounts are hidden** using homomorphic encryption and zero-knowledge proofs.
 
-The protocol builds on the Aptos Confidential Asset framework, which was originally released under the Apache 2.0 open-source license. In November 2025, Aptos Labs changed the license on their `aptos-core` repository to a more restrictive license, and subsequently introduced proprietary changes to their confidential asset module (v1.1) under the new terms. Movement's implementation uses only code that predates the license change, and all production-hardening modifications are clean-room implementations based on published, public-domain cryptography — no post-license-change Aptos code was used or referenced. These modifications include chain ID binding to prevent cross-chain proof replay, SHA3-512 tagged hashing for Fiat-Shamir challenges, and a Schnorr-based registration proof to prevent key registration abuse.

+**What observers still see.** A successful private transfer does not post the amount in cleartext, but it **does** emit `Transferred` with routing metadata, **compressed ciphertexts** for the moved amount and for the sender’s new actual balance and recipient’s new pending balance, a **flattened copy of the transfer sigma `x7s` commitment block** (`ek_volun_auds`; see [§5 `Transferred` event](#transferred-module-event)), the **`sender_auditor_hint`** bytes, and a **`memo`** field (reserved; empty in the current implementation). Indexers and compliance tooling should treat that event as the canonical on-chain record of those public payloads.

+**Sender auditor hint (`sender_auditor_hint`).** The sender may attach up to **`MAX_SENDER_AUDITOR_HINT_BYTES` (256)** opaque bytes (e.g. for off-chain auditors, indexers, or compliance references). The implementation **serializes the hint with BCS** and **appends those bytes to the transfer sigma Fiat–Shamir message** (after the commitment points, before the chain-id / sender / contract prefix is prepended and the tagged hash is taken). The same bytes must therefore be supplied when **generating** the proof off-chain and when calling **`confidential_transfer`** on-chain; changing the hint invalidates the proof. After successful verification, the hint is included on the **`Transferred`** module event (field reference below).

Integrators should not infer field names from legacy abbreviations alone; the list below is authoritative.
+
+| Field | Type (conceptual) | Meaning |
+| ----- | ----------------- | ------- |
+| **`from`** | Account address | Sender confidential account (the `signer` of the transfer). |
+| **`to`** | Account address | Recipient confidential account. |
+| **`asset_type`** | Object address | Fungible-asset **metadata object** address for the token (`object::object_address(&token)`). |
+| **`amount`** | Compressed confidential balance | **Ciphertext** for the amount moved, under the recipient key in **pending-balance** (four 16-bit chunk) layout. |
+| **`ek_volun_auds`** | `vector` | **Wire serialization of `sigma_proof.xs.x7s`:** for each auditor row in the verified transfer proof, **four** compressed Ristretto points (32 bytes each), concatenated **row-major** (auditor order matches the transfer’s auditor EK list; within each row, chunk indices 0–3). **Length = `128 × n`** bytes where `n` is the number of auditor rows (`n = 0` ⇒ empty vector). These are sigma **commitments** tied to the proof; they do **not** replace optional auditor ciphertexts and are not raw EK bytes. |
+| **`sender_auditor_hint`** | `vector` | Opaque bytes bound into the transfer sigma Fiat–Shamir hash (BCS) and copied into the event (max **256** bytes). |
+| **`new_sender_available_balance`** | Compressed confidential balance | Sender’s new **actual** (spendable) balance ciphertext after the debit. |
+| **`new_recip_pending_balance`** | Compressed confidential balance | Recipient’s new **pending** balance ciphertext after the credit. |
+| **`memo`** | `vector` | Reserved; the current implementation emits an **empty** vector. |
+
+**Why `ek_volun_auds` appears on-chain.** The transfer sigma proof already proves soundness; publishing the `x7s` block gives auditors and indexers a **stable, canonical byte string** that matches the verified proof’s auditor-row commitments without re-serializing the entire proof in the event.

+Every Fiat-Shamir challenge includes the chain ID and sender address as prefix bytes (prepended to the full message that already contains curve points, keys, balance encodings, and—**for transfers only**—the BCS encoding of `sender_auditor_hint`):

+$$\rho = \text{taggedhash}\left(\text{DST},\ \text{chainid}  \text{sender}  \text{contract}  \text{publicparams}  X_1  \cdots  X_n\right)$$
 
-$$\rho = \text{taggedhash}\left(\text{DST},\ \text{chainid}  \text{sender}  \text{publicparams}  X_1  \cdots  X_n\right)$$
+Here `publicparams` for the **transfer** sigma includes the usual public inputs (bases, sender/recipient/auditor keys, balance encodings, etc.) **followed by** `BCS(sender_auditor_hint)` so the challenge depends on the exact hint bytes the sender intends to publish.
 
 This binding ensures:
 
 - A proof generated for Movement mainnet cannot be replayed on testnet (or vice versa)
 - A proof generated by one sender cannot be replayed by a different sender
 - Proofs are tied to the specific transaction context

# Formal: Move bytecode model, refinement proofs, Move VM ↔ Lean
difftest

## Summary

Adds a **Lean 4 bytecode interpreter** (`AptosFormal.Move.*`),
**refinement proofs** (including a kernel-checked `vector::contains`
theorem in `Refinement/Vector.lean`), a **Rust ↔ Lean differential
harness** (`move-lean-difftest`) comparing the real Move VM to the Lean
evaluator on shared oracles, and supporting **stdlib vector specs** plus
**`AptosStd`** layout for crypto/hash modules. Workspace `Cargo.toml`
registers the difftest crate.

---

## What changed (concise)

| Area | Notes |
| ---- | ----- |
| **Move semantics** | `Value`, `Instr`, `State`, `Step`, `Native`,
`Programs` (Core + Vector bytecode, including real disassembly-backed
programs). |
| **Refinement** | `Refinement/Core.lean` (`rfl` programs);
`Refinement/Vector.lean` — `vector::contains` vs `Std.Vector.contains`.
|
| **Specs / tests** | `Std/Vector/Operations.lean`; `Tests/Defs`,
`Tests/Vector`. |
| **Difftest** | Crate `move-lean-difftest` (suites: vector, BCS, hash),
JSON oracle, Lean `DiffTest` runner;
[`difftest/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/difftest/README.md).
|
| **Layout** | `AptosStd` for Ristretto / SHA3-512; ConfidentialAsset
imports updated. |
| **Docs** |
[`formal/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/README.md)
(entry),
[`lean/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/lean/README.md)
(full runbook),
[`Move/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/lean/AptosFormal/Move/README.md)
(bytecode model + roadmap). |

## How to run — Lean proofs

Prerequisites: [elan](https://github.com/leanprover/elan) (Lean 4.24.0 +
Mathlib are pinned; see
[`lean/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/lean/README.md)).

```bash
cd aptos-move/framework/formal/lean
lake build
```

Optional: confirm no proof holes:

```bash
cd aptos-move/framework/formal/lean
grep -r "sorry" AptosFormal/ --include="*.lean"
```

(Axiom inventory and registration proofs: still in
[`lean/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/lean/README.md).)

---

## How to run — differential tests (VM vs Lean)

**All suites** (from repo root):

```bash
./aptos-move/framework/formal/difftest.sh
```

Per-suite runs, oracle paths, and flags:
**[`difftest/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/difftest/README.md)**.

---

## How to run — Move golden tests & byte consistency

Companion Move tests and golden-byte drift check (optional for this PR,
but part of the formal workflow). Commands use the **Movement** CLI
(`movement`), not `aptos`:

```bash
movement move test --package-dir aptos-move/framework/move-stdlib --filter formal_goldens
movement move test --package-dir aptos-move/framework/aptos-experimental --filter formal_goldens
bash aptos-move/framework/formal/check_golden_consistency.sh
```

Details:
[`lean/README.md`](https://github.com/movementlabsxyz/aptos-core/blob/move-lean/aptos-move/framework/formal/lean/README.md)
(sections *Companion Move golden tests* and *Checking Move / Lean golden
consistency*).

+# Plan: Differential testing — Confidential Assets (experimental)
+
+**Active scope (difftest track):** **Move VM ↔ Lean** differential testing (`move-lean-difftest` + `lake exe difftest` + optional merged e2e JSON). Success means **Tier A/B** green and honest progress on **§4.5** (including **Open** rows when claiming “properly difftested” beyond witness-only merged CA rows).
+
+**Parallel scope (formal verification track):** Machine-checked obligations (**L0–L5** in [`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)) — refinement, natives, storage — are **not** implied by difftest green alone. Both tracks are required for a peer-reviewable story that combines **regression evidence** (this doc) and **mathematical validity** (FV plan).
+
+**“Properly difftested *and* formally verified” (repo goal):** means **(C) both** in the FV plan’s sense — **(A)** crypto / proof-level obligations **and** **(B)** bytecode-vs-spec refinement (and higher **L3–L5** wiring as scoped), not difftest alone. See **[`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md) §1.3** for the explicit **(A) / (B) / (C)** table; this differential-testing plan covers the **L1** evidence lane and checklists that feed **(B)** but do not replace it.
+
+This document remains **empirical / finite**: it shows agreement on **recorded oracle cases**, not ∀-quantified correctness (see §2.2).
+
+**Prerequisites:** How difftest works today: [`difftest/README.md`](difftest/README.md), [`lean/README.md`](lean/README.md).
+
+**Move source audit (formal track):** [`CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md`](CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md) — API semantics / hardening notes from static review (not a product security sign-off).
+
+**Completion rubric (“are we done?”):** Use **§4.3** (what “professionally complete” CA difftest coverage looks like) and **§4.4** (tiers **A / B / C** — how to answer without hand-waving).
+
+---
+
+## 1. What this approach is
+
+- **Differential testing** here means: run the **same** inputs through  
+  (A) the **real Move VM** (Rust, in-repo), and  
+  (B) the **Lean** small-step evaluator (`AptosFormal.Move.Step` / `eval`),  
+  then compare **outputs** (and aborts / errors) encoded in a shared **JSON oracle**.
+- It is **empirical**, **finite**, and **regression-oriented**: it shows agreement on **the cases you run**, not a **proof for all inputs** or all execution paths.
+
+---
+
+## 2. What it **does** and **does not** show
+
+### 2.1 What differential testing **provides evidence for**
+
+| Claim | Strength |
+|--------|----------|
+| On oracle cases, **Lean’s bytecode model + native stubs** agree with **this VM + this compiled bytecode** for the **observed** return values, aborts, and any fields you put in the oracle (e.g. serialized return stack). | **Strong for those cases** — useful to catch transcription bugs, missing instructions, wrong native semantics, endian/layout mistakes. |
+| **Regression detection:** after a Move or Lean change, rerunning the suite flags **drift** before production. | **Strong operational value.** |
+| **Coverage growth:** more cases ⇒ more **confidence** (statistical / engineering), not a **theorem**. | **Inductive evidence only.** |
+
+### 2.2 What it **does not** prove
+
+| Non-claim | Why |
+|-----------|-----|
+| **Correctness for all inputs** | Only finitely many tests; no ∀. |
+| **No bugs** outside the oracle | Untested paths may still be wrong in VM *or* Lean. |
+| **Move source matches bytecode** | Difftest compares **engines on bytecode** (or serialized effects); **compiler correctness** is a separate obligation unless you always regenerate from the same pipeline and trust it. |
+| **Cryptographic security** (e.g. soundness of proofs, absence of forgeries) | Difftest checks **functional equality** on samples, not **security definitions**. |
+| **Lean natives “match the IRTF / independent crypto spec”** | You are checking **VM vs Lean**; both could disagree with an external reference unless you add separate audits or reference tests. |
+
+**One sentence for stakeholders:**  
+Differential testing gives **high-confidence alignment between two implementations on a maintained test set**; it does **not** replace **formal verification** (refinement, invariants, security proofs).
+
+---
+
+## 3. Important constraint: Lean must be able to **run** what you test
+
+In this repository, the **Lean side of difftest is not a second Move VM** — it is **`AptosFormal.Move`**’s evaluator over **transcribed** bytecode + **native** implementations in Lean ([`Native.lean`](lean/AptosFormal/Move/Native.lean), `ModuleEnv`).
+
+So **“entire confidential assets codebase under difftest”** still requires **engineering work** for every path you want to cover:
+
+1. **Bytecode** for the involved functions available to Lean (transcribe or generate from disassembly).  
+2. **`MoveInstr` / `Step`** support for every instruction those bytecodes use.  
+3. **Native bindings** in Lean for every native those paths call (or a deliberate **narrow scope** that mocks/stubs natives and only compares a **slice** of behavior — must be documented).
+
+**What you avoid compared to full formal verification:**  
+You do **not** need to write **refinement theorems**, **inductive invariants**, or discharge **proof obligations** in Lean. You **do** still need enough of the **same interpreter stack** that the Lean run is meaningful.
+
+**Rough effort comparison (intuition):**
+
+| Activity | Full verification plan | **This doc (difftest only)** |
+|----------|-------------------------|------------------------------|
+| Transcription + natives + `Step` extensions | Required | **Still required** for VM↔Lean on those paths |
+| Refinement proofs | Required | **Not required** |
+| Timeline for “all CA” | Multi-year (proofs + storage) | **Still large** (natives + globals if testing entrypoints), but **shorter than proof** work and parallelizable as **test oracles** |
+
+If the goal were **“VM-only golden tests”** (no Lean column), that would be a **different** (smaller) project — not the repo’s current **differential** design; we mention it in §9 as optional.
+
+---
+
+## 4. Scope — “entire confidential assets codebase”
+
+### 4.1 Move modules (same as formal plan)
+
+| Module | Path (under `aptos-move/framework/aptos-experimental/sources/confidential_asset/`) |
+|--------|--------------------------------------------------------------------------------------|
+| `confidential_asset` | `confidential_asset.move` |
+| `confidential_proof` | `confidential_proof.move` |
+| `confidential_balance` | `confidential_balance.move` |
+| `ristretto255_twisted_elgamal` | `ristretto255_twisted_elgamal.move` |
+| `confidential_gas_e2e_helpers` | `confidential_gas_e2e_helpers.move` (lower priority) |
+
+Plus **transitive** dependencies actually executed (stdlib, `aptos_std`, FA, …) — tracked per test case.
+
+### 4.2 What “coverage” means without proofs
+
+Define **coverage dimensions** explicitly (checklist per milestone):
+
+- [ ] **Functions:** every `public` / `public(friend)` / `entry` you care about appears in at least one oracle.  
+- [ ] **Branches:** happy path + representative **abort** / `none` / verification-failure paths where observable.  
+- [ ] **Natives:** each native on a hot path has at least one case (or is listed as **out of scope** for Lean column).  
+- [ ] **Auditors / optional features:** toggled in dedicated cases.
+
+These bullets are a **minimal inventory checklist**; **§4.3** is the **full professional bar**, and **§4.4** is how to report **which tier (A/B/C)** you satisfy.
+
+### 4.3 Professionally complete confidential-asset difftest coverage (quality bar)
+
+This subsection is **normative for how to talk about “done”** in reviews and when asking assistants: it does **not** redefine Phase 6.x delivery dates, but it **does** define what **“professionally acceptable / complete difftest coverage for CA”** means in industry terms.
+
+**Complete ≠ formal verification.** Completeness here means: **stated scope**, **evidence for every in-scope risk class you claim**, **no undisclosed stubbing on security-critical paths**, and **disciplined oracles** — not “every `entry` in Move has a Lean row tomorrow.”
+
+#### (i) Scope contract
+
+- **In:** which modules and which surfaces (`public` helpers, serializers, crypto primitives, `deserialize_*` edges, …) are claimed by **`move-lean-difftest` + Lean**.
+- **Out:** what is **explicitly not** in this pipeline (typical examples: full economic abuse, gas, liveness, **proof soundness**, “Lean matches RFC” without a third reference).
+- **Elsewhere:** what is covered only by **VM-only** or **e2e** (see **§7.0**) — still valuable, but **not** “VM↔Lean difftest” for those rows.
+
+Until **in / out / elsewhere** is written (inventory + this doc), “complete” is undefined.
+
+#### (ii) Equivalence-class coverage (not row count)
+
+For every **in-scope** observable API, professionally acceptable coverage includes **representatives per class**, not only happy paths:
+
+- **Lengths / layouts:** empty, sub-min, exact boundary, over-long; `Option` / abort outcomes recorded in the oracle where observable.
+- **Encodings:** `to_bytes` / `from_bytes`, compress / decompress, wrong wire layouts.
+- **Algebra (where claimed):** identities, inverses, relations that the math guarantees on stated domains; assignment vs functional forms when both exist.
+- **Chunking:** parameterized or systematic coverage over chunk indices / amount patterns (not only a few hand-picked constants).
+- **Cross-representation:** same semantic value built two supported ways (e.g. constructors that should agree on `balance_equals` / `balance_c_equals` / `is_zero`).
+
+#### (iii) Cryptographic primitives
+
+- **Vectors:** known-answer or **independent** gold vectors where feasible — not only self-consistency between VM and a second engine.
+- **Invalid inputs:** wrong lengths, non-canonical encodings if the API distinguishes them.
+- **Optional:** small **seeded-random** corpora VM↔Lean for hot paths (still finite; document seeds and scope).
+
+#### (iv) `confidential_proof` — staged honesty
+
+- **`deserialize_*`:** structure / length classes leading to `None` vs `Some`; if you claim deserialization correctness, add a **corpus of valid serialized proofs** from the real prover or harness (versioned bytes).
+- **`verify_*`:** either **VM-only / e2e** with a large, versioned accept/reject corpus (**§7.0**), or **VM↔Lean** only when Lean actually runs the same verification semantics. **Undocumented `ldTrue` stubs on `verify_*` are smoke, not “complete verify difftest.”**
+
+#### (v) `confidential_asset` transactional surface
+
+Professional **product** confidence for the asset module usually requires a **scenario matrix** (register, deposit, withdraw, transfer, rotate, normalize, auditor variants, failure modes) with **observable oracles** (state, events, abort codes) — typically **e2e / integration** (**§7.0**, **§7.1**). The **`move-lean-difftest`** JSON column may cover only **globals-free slices** (**Option B**); that gap must stay **explicit** in [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md).
+
+#### (vi) Second-column (Lean) fidelity
+
+Document, per row or per path, one of:
+
+- **Bytecode + natives** intended to track production semantics, or  
+- **Stub / trivial bytecode** that matches the VM **only on that oracle input** (must be obvious in `Programs/Confidential*.lean` + inventory).
+
+Stakeholders should never have to guess which applies.
+
+#### (vii) Process (non-negotiable)
+
+- **Deterministic** oracle regeneration from pinned toolchain / features.  
+- **CI** runs VM → JSON → Lean for all non-`skip_lean` rows relevant to CA.  
+- **Inventory + changelog** when scope or stubs move.  
+- **Triage rule** when VM and Lean disagree (which column is ground truth for regression).
+
+---
+
+### 4.4 Answering “Are we done with confidential-asset difftest coverage?”
+
+Use **named tiers** so answers are not ambiguous:
+
+| Tier | Meaning | Typical evidence |
+|------|---------|------------------|
+| **A — Pipeline complete (declared slice)** | Every **VM↔Lean** row in the maintained oracle(s) passes; every symbol the inventory marks as **VM↔Lean** for CA suites either has a representative case **or** an explicit **waived / blocked** note; no **undocumented** stubbing. | Green `lake exe difftest` on pinned JSON; [`confidential_assets.md`](difftest/inventory/confidential_assets.md) matches reality. |
+| **B — Professionally strong** | **Tier A** plus **§4.3 (ii)–(vii)** to a degree the team signs off on (equivalence classes, vectors where promised, proof/entrypoint staging honest, Lean fidelity documented). | Reviewed coverage matrix + external vectors where claimed. |
+| **C — Product-complete CA** | **Tier B** plus **transactional / full `verify_*`** evidence the product relies on — usually **§7.0 e2e** + optional export (**§7.1-B**), **not** `move-lean-difftest` alone unless Lean store + FA + proof natives exist. | E2e suite + optional merged oracle; documented Lean witness limits. |
+
+**How to answer in one sentence**
+
+- If only **Tier A** is satisfied: **“Difftest is green for the declared VM↔Lean oracle slice; CA as a whole is not ‘fully difftested’ unless Tier B/C criteria are separately claimed.”**  
+- If **Tier B** is satisfied: **“CA difftest meets the professional bar we documented in §4.3–4.4.”**  
+- **Never** say “fully difftested” for all of CA without stating **which tier** and pointing at **§7** for entrypoints / full verification.
+
+**Assistant / reviewer default:** when the user asks **“Are we done?”**, respond with **current tier (A/B/C)** + **one concrete gap** from **§4.3** or the inventory (highest risk first).
+
+**Important:** **Tier C is not a single deliverable** you can “finish” in one change set. Treat **§4.5** as the living checklist until the team signs off or explicitly narrows scope.
+
+---
+
+### 4.5 Traceability — “Full” (Tier C) vs this repository (living checklist)
+
+Use this table to avoid arguing from slogans. **Update the Status column** when work lands.
+
+| §4.3 / §4.4 requirement | Where it lives in-repo | Typical status (check in PRs) |

+
+**Bottom line for assistants:** **“Full difftests for confidential assets” (Tier C)** means **this table’s Tier-C rows + Tier B evidence** are satisfied **and** the team accepts **Lean witness limits** until the **Open** rows close. **Do not** claim Tier C solely from harness row count.

+- New suite(s), e.g. `confidential` or `confidential_balance` / `confidential_proof` / … registered in [`difftest/src/suites/mod.rs`](difftest/src/suites/mod.rs) (pattern: [`vector.rs`](difftest/src/suites/vector.rs)).
+- **Load** compiled packages that include `aptos_experimental` + dependencies (same style as existing suites: `InMemoryStorage`, publish, invoke).
+- For each case: build **args**, run VM, serialize **results** (return values, abort code, optional **event** bytes if needed) into the oracle JSON.
+
+### 5.2 JSON schema
+
+- Extend [`schema.rs`](difftest/src/schema.rs) / Lean [`DiffTest/JsonParser.lean`](lean/AptosFormal/DiffTest/JsonParser.lean) if CA cases need richer payloads (large `vector`, multiple return values, structured errors).
+- Version the schema if old oracles must keep working.
+
+### 5.3 Lean (`lake exe difftest`)
+
+- Extend [`DiffTest/Runner.lean`](lean/AptosFormal/DiffTest/Runner.lean) (or a sibling) to:
+  - parse CA cases;
+  - map case → **`ModuleEnv`** function index + **decoded `MoveValue` args**;
+  - run `eval` / `evalProg` with sufficient **fuel**;
+  - compare to oracle (same equality strategy as vector/BCS/hash).
+
+### 5.4 `ModuleEnv` for CA
+
+- Add a **`caModuleEnv`** (or extend `stdModuleEnv`) in new `Programs/Confidential*.lean` files: function table + **native dispatch** aligned with what CA bytecode calls.
+- **No refinement files required** — only enough definitions for **evaluation** to complete or abort consistently.
+
+---
+
+## 6. Phased plan (difftest-only)
+
+**Numbering:** The roadmap defines **Phases 0–5 only** (subsections below). **There is no Phase 6.** Later headings **§7–§9** are **other document sections** (evidence wording, optional VM-only note, maintenance) — they are **not** “Phase 7 / Phase 8 / Phase 9.” If your editor shows “Phase 5” followed by “7,” that jump is **section** numbering (6 = phased plan, 7 = evidence), not a missing delivery phase.
+
+### 6.0 Honest scope — what “implemented” means here
+
+The **calendar-style** subsections below (especially Phase **2–4** timelines) describe **breadth of coverage** that can take many weeks. What is **actually in the tree** today is narrower:
+
+| Phase | In repo today | Still open (same phase number) |
+|-------|----------------|--------------------------------|
+| **1** | CA smoke in the harness + Lean + CI path | — |
+| **2** | Many `confidential_balance` VM cases + Lean **stub** `ModuleEnv` matching VM on those oracle rows | Full bytecode transcription / evaluator paths for every hot native; every public helper in §4 inventories |
+| **3** | Constants + empty `deserialize_*`; **registration FS golden `msg`** (161 B) VM↔Lean via `TranscriptAlignment`; deterministic Schnorr roundtrip VM-only in harness; SHA3-512 on BP DST VM↔Lean | **Friend-only** `verify_registration_proof` on **production** bytecode still lives in **e2e** (`§7.0`), not in `head.mrb` harness. **Lean:** no executable Ristretto verification in `eval` yet — `verify_*` on full proof blobs and **Bulletproof verify end-to-end in Lean** remain **formal-verification-track** scope ([`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)), not `lake exe difftest`. |
+| **4** | **Option B** layer smoke + **Option B+**: `global_resource_smoke` suite — real `borrow_global` on a published `has key` resource at `@std` in the **same** JSON oracle as other suites | **FA / fungible store / `confidential_asset::register` entrypoints** in VM↔Lean JSON: still **§7.0 e2e** + **merged fragment** (`skip_lean` rows). **Lean note:** `MachineState` + `GlobalResourceKey` exist; FA + CA globals in `eval` are not implemented. |
+| **ElGamal** | Suite `confidential_elgamal`: VM oracles for **non–`test_only`** `public` APIs; Lean stubs indices 20–31 plus **`ciphertext_add_assign` / `ciphertext_sub_assign`** witnesses at indices **53–54** | Field access on `CompressedCiphertext` internals (no public getters); `#[test_only]` keygen / `new_ciphertext*` |
+| **5** | `schema_version`, `ORACLE_CHANGELOG.md`, regen workflow via script + CI | Optional nightly fuzz; no automated “regen oracle on every CA API change” beyond developer/CI runs |
+
+So: **infrastructure and a real differential slice are done**; **full Phase 2–4 depth from the tables is not.** Section **§4.2** checkboxes stay open until coverage catches up.
+
+### Phase 0 — Inventory and case design (**complete**)
+
+**Deliverables (done)**
+
+- Hub methodology + suite registry: [`difftest/INVENTORY.md`](difftest/INVENTORY.md).
+- Confidential assets + template tables: [`difftest/inventory/`](difftest/inventory/) (`confidential_assets.md`, `move_framework_template.md`).
+- Rust harness: `--list-suites`, dynamic `--suite` help / errors from `all_suites()`; [`difftest.sh`](difftest.sh) supports `--list-suites` (skips Lean).
+- **Discipline:** VM oracle is ground truth per run; mismatches are investigated — Move code is **not** assumed correct; oracles are not hand-edited to force Lean passes.
+
+---
+
+### Phase 1 — Harness + one end-to-end smoke case (2–6 weeks)
+
+**Deliverables**
+
+- [x] One Rust-generated oracle for **one** CA-invoking scenario (simplest: helper that only touches balance + crypto already partially modeled, or **pure** deserialization path).
+- [x] Lean runner executes **that** case; `difftest.sh` forwards `--suite confidential` (meta id expanding to balance + proof + layer smoke).
+- [x] CI job: generate oracle + run Lean — [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml) (path-filtered); default policy remains **generated** oracle (see [`difftest/README.md`](difftest/README.md)).
+
+**Success criterion:** Green CI on that single case.
+
+---
+
+### Phase 2 — `confidential_balance` coverage (4–10 weeks)
+
+**Deliverables**
+
+- [x] Oracles for **public** helpers: zero balance, compress/decompress roundtrip, add (fixed inputs), serialization size checks, chunk constants, `Option` deserialization edge cases, etc.
+- [x] Lean: **native stubs** in `AptosFormal.Move.Programs.Confidential` aligned with VM outputs on oracle inputs (not full bytecode transcription for every path — see inventory skip list).
+
+**Success criterion:** Suite runs **N** cases; documented list of **skipped** functions and why — [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md).
+
+---
+
+### Phase 3 — `confidential_proof` (8–20 weeks, parallel by verifier)
+
+**Sub-tracks**
+
+- [x] **Registration transcript (partial):** harness rows **`test_registration_fs_message_golden_move`** / **`test_registration_fs_message_golden_move_second`** return the **161-byte** FS `msg` for the two formal goldens; Lean uses **`TranscriptAlignment.expectedRegistrationFsMsgMoveGolden`** / **`expectedRegistrationFsMsg2`** (same bytes as [`formal_goldens_registration.move`](../aptos-experimental/tests/confidential_asset/formal_goldens_registration.move)). Framework-vs-helpers rows **170** / **173** VM-pin **`registration_fs_message_for_test`** on each scenario. This tightens **transcript** alignment; it is **not** a `verify_registration_proof` **curve** check in `eval`.
+- [x] **Harness Schnorr roundtrip:** `difftest_registration_helpers::registration_roundtrip_vm` (VM). Lean column: **bool stub** until Ristretto/group operations are executable in `AptosFormal.Move` natives.
+- [x] **Partial — production curve verify in harness JSON:** `verify_registration_proof_for_difftest` + deterministic prover on the **`registration_roundtrip_vm`** fixture (`test_registration_proof_framework_deterministic_verify_roundtrip`, Lean **171** = same `execVerifyRegistrationProof` column as **35**). Full **`register` → friend `verify_registration_proof`** on transactions remains **e2e** canonical (`§7.0`).
+- [ ] **Transfer / withdraw / normalize / key rotation in harness+Lean:** same as above; **e2e merged oracle** records real `verify_*` on transactions (`skip_lean`).
+
+**Native-heavy areas:** range proof / sigma / Bulletproofs — **VM↔Lean equality on full verify** would require Lean natives matching Aptos Bulletproofs + Ristretto batch interfaces; that is **orthogonal** to this difftest roadmap (treat as proof or reference-library work).
+
+---
+
+### Phase 4 — `confidential_asset` entrypoints (depends on Phase 2–3 + storage)
+
+**Challenge:** Entrypoints touch **global storage** and **FA**; current `Move.*` model **omits globals** (see [`Move/README.md`](lean/AptosFormal/Move/README.md)).
+
+**Options (pick explicitly):**
+
+| Option | Difftest “entire codebase” meaning |
+|--------|--------------------------------------|
+| **A. Extend Lean state with a minimal store** | True VM↔Lean on entrypoints; **large** model work, still **no proofs**. |
+| **B. Test only `fun` paths** that do not need globals | Partial “entire” — document gap. |
+| **C. VM column only** for entrypoints; Lean for **internal** slices | Hybrid; not pure differential on entrypoints. |
+
+**Chosen for this repo (current track): Option B** for `confidential_asset` **module paths**, plus **§7.1-B** for **full stack (FA + globals + `verify_*`)** evidence: the **merged** oracle [`difftest_ci_merged.json`](difftest/difftest_ci_merged.json) (CI) = `move-lean-difftest` harness + **e2e** [`OracleFragment`](../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs) rows with **`skip_lean: false`**, so Lean runs the **witness** bytecode paths mapped in `Runner.lean` (not full FA + real `verify_*` replay in Lean). E2e success rows include **`bool` `true`** as a compact witness that the scenario’s VM checks passed.
+
+**New harness suite:** `global_resource_smoke` — `borrow_global` on a resource published at `@std` via BCS from Rust (not FA).
+
+The plan should **name the chosen option** in the README for this suite.
+
+---
+
+### Phase 5 — Regression and maintenance
+
+**Deliverables**
+
+- [x] Oracles regenerated on compiler / CA **API** changes; changelog entry when oracle format bumps — [`difftest/ORACLE_CHANGELOG.md`](difftest/ORACLE_CHANGELOG.md) + `schema_version` in JSON (`CURRENT_SCHEMA_VERSION` in Rust).
+- [ ] Optional: nightly **fuzz**-generated cases (VM only first; add Lean when safe). *Not implemented in CI;* track as a separate harness if random/property cases are needed beyond `move-lean-difftest`’s fixed vectors.
+
+---
+
+## 7. Stretch scope — three requested tracks (dependency map + what already exists)
+
+This section records **gaps for `move-lean-difftest` + Lean**, and **where the repo already runs the heavier VM story** (transactional CA + real proof verification on bytecode).
+
+### 7.0 **Already in tree:** transactional VM, `register`, and full `verify_*` / `verify_registration_proof` paths
+
+**Location:** [`aptos-move/e2e-move-tests/src/tests/confidential_asset_e2e.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e.rs)
+
+**What it does (VM column only — not `lake exe difftest`):**
+
+- Builds **`aptos-experimental`** with **`test_mode = true`** and injects **all `0x7`** modules (plus a **test-mode `0x1`** stdlib graph) into a **`MoveHarness`** so `#[test_only]` helpers such as **`prove_registration`** are available.
+- Re-seeds **`FAController` / `init_module_for_testing`** so on-disk layout matches injected `confidential_asset` bytecode.
+- Drives **real entry transactions**: **`register`** (which calls **`verify_registration_proof`** on the **friend** path), **`deposit`**, **`rollover`**, **`confidential_transfer`**, **`withdraw_to`**, **`rotate_encryption_key`**, freeze/auditor scenarios, etc., with **valid** proof payloads assembled in Rust / Move helpers inside that file.
+
+**How to run (from repo root):**
+
+```bash
+# All tests whose names match the module filter (can be slow; some environments need a larger stack).
+RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests confidential_asset_e2e -- --test-threads=1
+```
+
+Example **single** scenario (register + deposit + rollover + gas profile hook):
+
+```bash
+RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests tests::confidential_asset_e2e::confidential_asset_register_deposit_rollover_and_gas -- --exact --test-threads=1
+```
+
+**Relation to `move-lean-difftest`:** this is the **canonical** answer today for “**full VM** behavior including globals, FA, and **`confidential_proof::verify_*`** on real structs.” It does **not** produce the **JSON oracle** consumed by Lean; bridging **e2e → `difftest_oracle*.json`** (or extending Lean to replay harness state) remains future work (see **7.1-B** / **7.2**).
+
+### 7.1 `confidential_asset` in **`move-lean-difftest`** (still Option B)
+
+**Why `move-lean-difftest` alone is still limited:** `register`, `deposit_to`, … **`acquire`** store + FA; the harness uses **`InMemoryStorage` + `execute_loaded_function`**, not a full Aptos transaction. **`head.mrb`** omits **`#[test_only]`** symbols, so **`register_for_testing`** etc. are **not** in that compiler graph.
+
+**Forks if you want VM↔Lean on entrypoints here:**
+
+| Track | Idea | Lean column? |
+|-------|------|----------------|
+| **7.1-A** | Extend difftest session with **minimal global store + FA** (or share harness code with e2e) | After `AptosFormal.Move.State` matches |
+| **7.1-B** | Emit **JSON** from **e2e** (or `aptos move test`) for VM-only rows, optional `lake exe` skip | VM-only until Lean store |
+| **7.1-C** | **Option A** from Phase 4 (§6): full Lean container store + FA | Largest Lean surface |
+
+**Suggested order:** treat **§7.0** as source of VM truth for entrypoints → add **7.1-B** export or **7.1-A** only if you need the **same JSON pipeline** as vector/BCS suites.
+
+### 7.2 `confidential_proof` in **`move-lean-difftest`** vs **e2e**
+
+**On real bytecode today:** **`verify_registration_proof`** runs inside **`confidential_asset::register`** in **§7.0** tests. **`verify_withdrawal_proof` / `verify_transfer_proof` / …** run on **`withdraw_to` / `confidential_transfer` / `rotate_*`** paths in the same file.
+
+**On `move-lean-difftest` today:** only **release-visible** smoke (`deserialize_*` on empty, constants). Friend-only **`verify_registration_proof`** and **`prove_*`** are **not** in **`head.mrb`**.
+
+**Lean:** still **no** faithful sigma + Bulletproofs over full proof blobs in `AptosFormal.Move.Programs.Confidential`; stubs only match the **narrow** oracle cases.
+
+**Suggested order:** optional **JSON export** from e2e scenarios → **VM-only** rows in schema (§9) → long-term **Lean natives** or bytecode transcription (**7.3**).
+
+### 7.3 “True” bytecode parity in Lean (whole CA modules, not stub `ModuleEnv`)
+
+**What it means:** For each function under test, **disassembled** `MoveInstr` in Lean (or generated from the same compiler pipeline), **`Step`** coverage for **every** instruction, and **every** `native` on those paths bound in `AptosFormal.Move.Native` with semantics matching the VM — **then** `eval` against `realModuleEnv`-style tables instead of **`Programs/Confidential` stub `FuncDesc`**.
+
+**Why it is large:** `confidential_proof.move` alone is thousands of lines with many natives (Ristretto, SHA3, Bulletproofs, …). This is **orthogonal** to “no refinement proofs” — you still need a **complete interpreter slice**.
+
+**Suggested order:** automate **bytecode export** for one **`confidential_balance`** `public fun` already in the oracle → prove **`Step`** + natives for **that** function end-to-end → repeat module-by-module. CA-wide parity is a **program**, not one task.
+
+---
+
+## 8. Appendix — Evidence summary (for audits / leadership)
+
+**You can honestly claim:**
+
+- “On **{N}** automated cases, the **Lean bytecode evaluator** and the **Aptos Move VM** **agreed** on outputs for **{listed}** confidential-asset paths, revision **{git SHA}**, toolchain **{versions}**.”
+
+**You should not claim:**
+
+- “Confidential assets are **formally verified**.”  
+- “**All** inputs behave correctly.”  
+- “**Security** of the cryptographic protocol follows from difftest.”
+
+**Optional one-liner:**  
+Differential testing is **continuous alignment evidence** between two implementations; refinement proofs would be **mathematical obligation** — orthogonal.
+
+---
+
+## 9. Appendix — Optional: VM-only oracle suite (out of scope for “difftest” name)
+
+If the team wants **fast** coverage **without** extending Lean:
+
+- Maintain **JSON (or Move test) goldens** produced **only** by the VM.  
+- That is **not** “Move ↔ Lean differential testing” in this repo’s sense; it is still valuable as **VM regression**.  
+- Can be a **Phase 0** deliverable feeding later VM↔Lean cases (same inputs, once Lean is ready).
+
+---
+
+## 10. Appendix — Document maintenance
+
+- Update **Phase** status and **option A/B/C** for `confidential_asset` when decided.  
+- When CA difftest **scope or stubs** change, update **§4.3–4.4** if the **completion rubric** or **tier definitions** shift; keep [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md) aligned so **“which tier are we?”** stays answerable from the repo.  
+- Link this file from [`formal/README.md`](README.md) if you want discoverability.
+
+---
+
+## 11. Appendix — “Full stack in JSON / full verify in Lean”: what this repo does **not** promise
+
+Requests sometimes bundle: **FA + globals + `borrow_global`**, **real `verify_*` on non-trivial proofs in the Lean column**, **full Bulletproof verification in Lean**, and **machine-checked refinement of `verify_registration_proof` inside `lake exe difftest`**.
+
+| Ask | In-repo status |
+|-----|----------------|
+| FA + CA entrypoints + real proofs **in the VM oracle** | **Yes (VM column + merged oracle):** [`confidential_asset_e2e_oracle_impl.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs) scenarios + merge into `difftest_ci_merged.json`. Lean **compares** mapped rows (`skip_lean: false`) on **witness** programs, not the full transactional stack. |
+| FA + the same in **Lean `eval`** | **No:** would require a large `AptosFormal.Move` store + FA + confidential bytecode + natives — see [`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md). |
+| **Full Bulletproof verify in Lean** (matching VM bit-for-bit on proof blobs) | **No:** not implemented; difftest checks **SHA3-512** on the BP **DST string** and other **narrow** stubs only. |
+| **Refinement proof** of registration inside the difftest runner | **No:** registration **math** lives under `AptosFormal.Experimental.ConfidentialAsset.Registration.*` (e.g. `SchnorrCompleteness`, `TranscriptAlignment`); `lake exe difftest` is **operational** alignment on oracle rows, not a proof obligation discharge. |
+| **`borrow_global` in harness JSON** | **Yes (VM↔Lean):** suite `global_resource_smoke` (`difftest_global_smoke.move` + published `Counter`). |
+
+**Local CI mirror:** `./aptos-move/framework/formal/difftest.sh` (harness + Lean); with `DIFTEST_MERGE_CA_E2E=1`, e2e export + merge + Lean on `difftest_ci_merged.json` (same as [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml)).

+# Plan: Formal verification for Confidential Assets (experimental)
+
+**Dual-track program (confidential assets):**
+
+1. **Difftest / alignment** — milestones, merged e2e oracle, and **§4.5 checklist** (“properly difftested” in the repo’s sense): **[`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md)**.
+2. **Formal verification** — **L0–L5** obligations, refinement, and proof hygiene: **this document**.
+
+Neither track replaces the other: difftest catches **VM↔model drift** on goldens; FV is what supports **“Move implements the intended math”** claims for reviewers.
+
+**Program bar (“properly difftested *and* formally verified”):** both tracks are required, in the following sense (see **§1.3**):
+
+- **(A) Crypto / proof obligations** — machine-checked properties of the **intended math** (transcripts, hashes, curve / proof interfaces, registration soundness-style lemmas, …), largely **L0** and crypto-facing workstreams here.
+- **(B) Bytecode vs spec** — connecting **Lean `Move` execution** (and eventually module wiring / storage) to those specs via **refinement** and **`eval`**-level proofs (**L2–L5** as applicable), not only oracle agreement on finite rows.
+- **(C) Both (A) and (B)** — this repo’s **completion** goal for CA formal work is **(C)**: difftest and corpora are **necessary regression evidence**; **(A)** and **(B)** together are what “formally verified” means here, unless a milestone explicitly scopes down (e.g. oracle-only L1 for a slice).
+
+---
+
+This document is a **roadmap** for extending the **`AptosFormal`** stack so that **confidential assets** (`aptos_experimental::confidential_*` and dependencies) can be **machine-checked** with a clear statement of what is proved against what. It is written for engineers and proof engineers working in `aptos-move/framework/formal/`.
+
+**Related docs**
+
+- Lean build / difftest workflow: [`lean/README.md`](lean/README.md), [`difftest/README.md`](difftest/README.md)
+- Bytecode model + roadmap: [`lean/AptosFormal/Move/README.md`](lean/AptosFormal/Move/README.md)
+- Registration **spec-level** review (today’s main CA formal work): [`REGISTRATION_VERIFY_REVIEW.md`](REGISTRATION_VERIFY_REVIEW.md)
+- CA Move **audit notes** (semantics / harness sharp edges while building formal artifacts): [`CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md`](CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md)

+## 1. Definitions
+
+### 1.1 “Confidential assets” in this repo
+
+**In scope (Move sources, relative to repo root):**
+
+| Layer | Module(s) | Path |
+|-------|-----------|------|
+| Asset controller | `aptos_experimental::confidential_asset` | `aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_asset.move` |
+| Proofs / verification | `aptos_experimental::confidential_proof` | `…/confidential_proof.move` |
+| Encrypted balances | `aptos_experimental::confidential_balance` | `…/confidential_balance.move` |
+| Twisted ElGamal | `aptos_experimental::ristretto255_twisted_elgamal` | `…/ristretto255_twisted_elgamal.move` |
+| Test / harness helpers | `aptos_experimental::confidential_gas_e2e_helpers` | `…/confidential_gas_e2e_helpers.move` |
+
+**Transitive dependencies (must be in scope for *full* entrypoint verification):**
+
+- `aptos_std::ristretto255`, `aptos_std::aptos_hash`, Bulletproofs / range-proof APIs as used from Move
+- `std::bcs`, `std::vector`, `std::option`, `std::signer`, …
+- **Fungible asset / object / dispatchable FA** paths used by `confidential_asset` entrypoints
+- Any **governance / allow-list** modules actually invoked
+
+### 1.2 What “formally verified” means here (levels)
+
+Use **explicit levels** so stakeholders do not confuse them:
+
+| Level | Meaning | Example |
+|-------|---------|---------|
+| **L0 – Spec only** | Pure Lean `Prop` / functions aligned to Move **source**; no bytecode. | Today: `AptosFormal.Experimental.ConfidentialAsset.Registration.*` for `verify_registration_proof` math + transcript goldens. |
+| **L1 – Differential** | Real VM vs Lean **evaluator** on shared oracles; **not** a proof. | Today: `vector`, `bcs`, `hash`, **`global_resource_smoke`**, **`confidential_*`** harness suites + **merged CA e2e** JSON in CI; many merged CA rows use Lean **witness** stubs (constant returns) — see differential plan **§4.5 / §11**. |
+| **L2 – Bytecode refinement (local)** | For a **single** function or closed snippet: transcribed `CodeUnit` in Lean + `Move.step`/`eval` agrees with a **Lean spec** (possibly `sorry`-free under hypotheses). | Today: `Refinement/Core.lean`, `Refinement/Vector.lean` for stdlib-shaped code. |
+| **L3 – Bytecode + module wiring** | Correct `ModuleEnv`, constant pool, **native dispatch**, `Call`/`Ret` across **multiple** functions in one compilation unit. | Not done for CA. |
+| **L4 – Resource / global state** | Model **`borrow_global`**, `move_to`, signer, **FA stores**; proofs about **entrypoints** that touch storage. | **Not** in current `Move.Instr` “omitted” set; largest extension. |
+| **L5 – End-to-end chain** | L4 + **compiler correctness** (Move source ↔ bytecode) or a **trusted** disassembly pipeline. | Optional; separate project from “verify this branch’s Move”. |
+
+The **completion scope** tag **(A) / (B) / (C)** (crypto vs bytecode-vs-spec vs **both**) is spelled out in **§1.3**; the levels above map onto those tags (e.g. **(A)** ↔ L0-heavy crypto, **(B)** ↔ L2–L5, **L1** ↔ difftest evidence).
+
+**“All of confidential assets formally verified”** in a **single milestone** is not realistic. This plan targets **L0 already in progress**, then **L1 → L2 → L3** in priority order, with **L4** as a **branching** track when entrypoint proofs are required.
+
+### 1.3 Program completion scope: **(A)**, **(B)**, and **(C)**
+
+Stakeholders sometimes split “formal verification” into *crypto proofs* vs *implementation proofs*. **For confidential assets in this program, “formally verified” means both:**
+
+| Tag | Meaning | Typical artifacts / levels |
+|-----|---------|------------------------------|
+| **(A)** | **Crypto / proof obligations** — the Move-facing **math and protocol** story is proved (or clearly axiomatized) in Lean **independently of** “does `eval` replay this bytecode.” | **L0** modules (e.g. registration transcript / Schnorr / hash lemmas), future BP / Ristretto specs as claimed in Workstream A. |
+| **(B)** | **Bytecode vs spec** — the **Lean Move model** (`Move.step` / `eval`, `ModuleEnv`, natives, later globals/FA) is shown to **implement** or **refine** the relevant specs on chosen units or entrypoints. | **L2** `Refinement.*`, **L3** module wiring, **L4** resources / FA, **L5** optional compiler-trust story. |
+| **(C)** | **Both** — the **intended bar** for “CA is formally verified” in repo documentation and planning: **(A)** without **(B)** leaves an execution gap; **(B)** without **(A)** can match wrong crypto. | Delivered incrementally per milestone; **L1 difftest** is **evidence**, not a substitute for **(C)**. |
+
+**Difftest (L1)** remains **essential** for **regression and alignment**, but it does **not** by itself satisfy **(A)** or **(B)**; it supports **(B)** by pinning concrete behaviors and **(A)** indirectly via goldens, not by proving ∀-properties.
+
+---
+
+## 2. Current baseline (move-lean / formal tree)
+
+### 2.1 Already present
+
+- **`AptosFormal.Move.*`**: partial bytecode instruction set, `Step`/`run`/`eval`, `ModuleEnv`, **`MachineState`** with abstract globals (`GlobalResourceKey`); **no** full `StructTag`+FA signer semantics, variants, or closures (see [`Move/README.md`](lean/AptosFormal/Move/README.md), [`difftest/STUB_POLICY.md`](difftest/STUB_POLICY.md)).
+- **`AptosFormal.Native`**: BCS (selected monomorphizations), `sha3_256`, vector-related natives — **not** CA’s full native surface.
+- **`AptosFormal.Refinement`**: small `rfl` programs + **`vector::contains`**-style universal proof for curated bytecode.
+- **`AptosFormal.Refinement.Confidential`** (**L2 / track B**): `eval confidentialModuleEnv …` agrees with **Move-constant** specs for CA harness rows — **`confidential_balance`** chunk / zero-serialization **`u64`** views (**0–4**), **Bulletproofs** UTF-8 DST + **`u64(16)`** num-bits + **SHA3-512** digest (**14** / **15** / **34**, full **`vector`** where applicable), **Fiat–Shamir sigma DST** getters (**43–46** / **51**, full **`mvU8Wire`** vs **`Programs.Confidential.fiat*SigmaDstBytes`**), **registration FS golden `msg`** (**38**, **`mvU8Wire`** vs **`Programs.Confidential.registrationFsMsgGoldenMoveBytes`**), **registration tagged-hash goldens** (**174** / **175**, **`mvU8Wire`** vs **`TranscriptAlignment.expectedTaggedHashGolden{,2}.toList`** via **`Programs.Confidential.registrationTaggedHashGolden*MoveBytes`**), **sigma wire length** **`bool(true)`** indices **128–130** and transfer-extension **131** / **133** / **135** / **137** / **139** / **141** / **143** / **145** / **147** / **149** / **151** / **153** / **155** / **157** / **159** / **161** / **163** / **165** / **167** (through **4224** B), FA stub **`faWriteBalance` + `faReadBalance`** round-trip (**169**, **`u64(9999)`** from empty **`faBalances`**), registration FS framework **`bool(true)`** (**170**), registration Schnorr verify on the fixed difftest fixture (**35** / **171**, same **`Operational.execVerifyRegistrationProof`** oracle), second FS golden **`vector`** + framework **`bool`** rows (**172** / **173**), empty **`serialize_auditor_*`** vectors (**36** / **37**), and pinned **`serialize_auditor_*`** wires (**114–127**); see `lean/AptosFormal/Refinement/Confidential.lean`.
+- **`move-lean-difftest`**: **`vector`**, **`bcs`**, **`hash`**, **`global_resource_smoke`**, **`confidential_balance`**, **`confidential_elgamal`**, **`confidential_proof`**, **`confidential_asset`** (layer), **`fa_stub`** ([`difftest/src/suites/mod.rs`](difftest/src/suites/mod.rs)); plus **e2e-exported** CA oracle fragments merged for CI (`DIFTEST_MERGE_CA_E2E`).
+- **`AptosFormal.Experimental.ConfidentialAsset.Registration.*`**: **L0** for **`verify_registration_proof`** (crypto story, transcript bytes, axioms/oracles) — **not** bytecode execution in Lean. **`TranscriptAlignment`** pins **`registrationChallengeScalarMove`** on each golden FS `msg` to **`scalarUniformFrom64Bytes`** of the matching **64**-byte tagged digest (`registrationChallengeScalarMove_golden1_msg_eq_uniform_expectedTaggedHashGolden`, `registrationChallengeScalarMove_golden2_msg_eq_uniform_expectedTaggedHashGolden2`). **`Operational`** includes **`execVerifyRegistrationProof_eq_some_iff_pointEqBool_of_parsed`** (post-parse success ↔ `pointEqBool` on the Schnorr LHS).
+- **VM↔Lean sigma wire lengths (L1-flavored, real `Step`):** indices **128–130** return **`bool(true)`** when the pinned **`deserialize_sigma_*.hex`** byte vectors have lengths **1152** / **1216** / **1792** (`ldConst` + `vecLen` + `eq`) — complements **M11** stubs on **`deserialize_*` `Some`** rows without claiming parser parity.
+- **Wire-level lemmas (L0-flavored, not `eval`):** `AptosFormal.Move.Programs.Confidential` pins VM auditor amount serializer bytes and proves small structural facts (e.g. **`serializeAuditorAmounts_mixed512_orders_distinct`**, **`serializeAuditorAmounts_mixed768_orders_distinct`** — permutations with identical multiset of balances but different vector order are byte-distinct; **`serializeAuditorEksThreeApointWireBytes_length`** / append characterization for **96**-byte triple-**A_POINT** EK wires; **`serializeAuditorEksFourApointWireBytes_length`** for **128**-byte quadruple-**A_POINT** EK wires; **`serializeAuditorEksFiveApointWireBytes_length`** and **`serializeAuditorEksFiveApointWireBytes_eq_deserializeRepeatConcat`** for **160**-byte quintuple-**A_POINT** EK wires vs the same repeat-concat used in sigma layout bytes; **`serializeAuditorEksSixApointWireBytes_length`** / **`serializeAuditorEksSixApointWireBytes_eq_deserializeRepeatConcat`** for **192**-byte sextuple-**A_POINT** EK wires; **`deserializeSigma18Scalars18PointsBytes_five_points_eq_serializeAuditorEksFiveApoint`** / **19** / **transfer** variants — the first five **A_POINT** slots in each checked **`deserialize_sigma_*.hex`** layout match the **160**-byte EK corpus; **`deserializeSigma18Scalars18PointsBytes_six_points_eq_serializeAuditorEksSixApoint`** (and **19** / **transfer** variants) match the first **six** compressed-point slots to the **192**-byte EK corpus), supporting difftest corpora without claiming full `deserialize_*` / `verify_*` in the evaluator.
+
+### 2.2 Gap
+
+There is **no** end-to-end continuous path yet from **full** **`confidential_asset` / `confidential_proof` / `confidential_balance` / `ristretto255_twisted_elgamal` bytecode** (including globals, FA, and real crypto natives) to **`Move.eval`** + **refinement** + **difftest**. **Partial track B** coverage for the **harness** module exists in **`Refinement.Confidential`** (constant views + sigma length rows); wiring **entrypoints**, **L3** calls, and **L4** state remains open.
+
+---
+
+## 3. Guiding principles
+
+1. **Prove the smallest meaningful slice first** (one function, one path, one oracle).
+2. **Separate concerns**: native crypto correctness vs VM stepping vs global storage vs compiler.
+3. **Difftest before hard proofs** for each new bytecode transcription — catches transcription and native wiring bugs early.
+4. **Reuse L0 specs**: refinement theorems should relate `eval` to existing `verifyRegistrationProofProp`-style definitions where possible, rather than duplicating math in prose.
+5. **Document proof obligations**: every `sorry`, axiom, and “trusted disassembly” must be listed for auditors (pattern already in [`lean/README.md`](lean/README.md) and [`REGISTRATION_VERIFY_REVIEW.md`](REGISTRATION_VERIFY_REVIEW.md)).
+
+---
+
+## 4. Dependency graph (conceptual)
+
+```text
+  aptos_std (ristretto, hash, …)     move-stdlib (bcs, vector, …)
+           \                           /
+            \                         /

+                   confidential_asset  ──► FA / object / globals (L4)
+```
+
+**Suggested verification order (bottom-up):**
+
+1. **Crypto primitives + twisted ElGamal** (natives + pure helpers).
+2. **`confidential_balance`** (chunking, homomorphic ops — mostly local).
+3. **`confidential_proof`** (sigma / range / deserialization — heavy natives).
+4. **`confidential_asset`** (composition + **storage**).
+5. **`confidential_gas_e2e_helpers`** (test-only / harness — lower priority unless product depends on it).
+
+---
+
+## 5. Workstreams (run in parallel where possible)
+
+### Workstream A — **Native and crypto specs**
+
+**Goal:** For every **Move native** invoked on CA paths, either:
+
+- implement **`List MoveValue → Option (List MoveValue)`** in Lean consistent with `AptosFormal.Std.*` / `AptosFormal.AptosStd.*`, or  
+- document an **`opaque` / axiom** boundary with a **reviewed** contract (weaker).
+
+**Tasks**
+
+- Build a **static call graph** from disassembled CA + dependencies (script or manual table): list each `native fun` and `Call` target.
+- For each native: map to existing Lean (`Std.Hash`, `Std.Bcs`, `AptosStd.Crypto`, …) or add new spec modules.
+- **Bulletproofs / range proof verification**: either full Lean spec (very large) or **oracle** for difftest + abstract interface for proofs (“if native returns `true`, then …”).
+- Align **tagged SHA3-512**, **scalar from bytes**, **decompress**, etc., with goldens already used in registration / Move tests.
+
+**Exit criteria**
+
+- A **checked-in table**: native name → Lean implementation status (`done` / `axiom` / `oracle-only`).
+
+**Partial (tree today):** high-level matrix + status legend for **`aptos_hash` / `ristretto255` / `ristretto255_bulletproofs`** vs CA modules — [`difftest/inventory/confidential_native_matrix.md`](difftest/inventory/confidential_native_matrix.md) (extend with **per-native** rows over time). **Difftest:** VM **`deserialize_*` → `Some`** on fixed sigma layouts (canonical zero scalar + **A_POINT** repeats + empty ZKRP byte vectors); checked-in **hex** (`deserialize_sigma_*.hex`, including transfer extensions **1920** / **2048** / **2176** / **2304** / **2432** / **2560** / **2688** / **2816** / **2944** / **3072** / **3200** / **3328** / **3456** / **3584** / **3712** / **3840** / **3968** / **4096** / **4224** B) + **`move-lean-difftest verify-corpora`** + Lean **`deserializeSigma*Bytes_length`** / prefix lemmas;

+
+---
+
+### Workstream B — **Lean bytecode model extensions**
+
+**Goal:** `MoveInstr` / `Step` / `State` support **every instruction** needed by chosen CA bytecode, or a **documented** reduction (e.g. “we only verify inlined core”).
+
+**Tasks**
+
+- For each target function: `movement move compile` + disassemble; diff against supported `MoveInstr` set; extend [`Instr.lean`](lean/AptosFormal/Move/Instr.lean) / [`Step.lean`](lean/AptosFormal/Move/Step.lean) as needed.
+- Revisit **omissions** from [`Move/README.md`](lean/AptosFormal/Move/README.md): **globals**, **variants**, **closures** — decide **per milestone** whether to add them or keep verification **intraprocedural** (function body only with **assumed** initial locals / heap snippet).
+
+**Exit criteria**
+
+- `lake build` green; **smoke** `native_decide` tests run for new instruction paths.
+
+---
+
+### Workstream C — **Transcription and `ModuleEnv`**
+
+**Goal:** For each verified function: **`Array MoveInstr`** + **`FuncDesc`** + **constant pool** + **native table** entries match the **compiler output** for this repo revision.
+
+**Tasks**
+
+- Add `Programs/Confidential*.lean` (or similar) mirroring today’s [`Programs/Vector.lean`](lean/AptosFormal/Move/Programs/Vector.lean) pattern: hand-written + **real** `real…Code` where useful.
+- Extend [`Programs.lean`](lean/AptosFormal/Move/Programs.lean) `stdModuleEnv` (or a dedicated **`caModuleEnv`**) with function indices; keep **disassembly provenance** in comments (commit hash, compiler version).
+- Serialization: Move **BCS / vector-of-u8** arguments must match Lean `MoveValue` decoding used by `eval` and difftest.
+
+**Exit criteria**
+
+- For each transcribed function: **bit-identical** or **semantically checked** against Rust VM on a **golden** input (Workstream D).
+
+---
+
+### Workstream D — **Differential testing (CA suite)**
+
+**Goal:** New **`move-lean-difftest`** suite (e.g. `confidential` or split by submodule) following [`difftest/README.md`](difftest/README.md).
+
+**Tasks**
+
+- **Rust:** load compiled packages containing CA modules (same layout as today’s vector suite: `InMemoryStorage`, publish modules, invoke script or test entry).
+- **Oracle JSON schema:** extend [`schema.rs`](difftest/src/schema.rs) if needed: function id, serialized args, expected **return values** / **abort** / optional **event** payloads.
+- **Lean:** extend [`DiffTest/Runner.lean`](lean/AptosFormal/DiffTest/Runner.lean) (or parallel) to dispatch CA cases to `eval` / `evalProg` with **`caModuleEnv`**.
+- **`difftest.sh` / CI:** register the new suite in [`suites/mod.rs`](difftest/src/suites/mod.rs).
+
+**Exit criteria**
+
+- One-command run from repo root; CI fails on VM vs Lean mismatch for registered goldens.
+
+---
+
+### Workstream E — **Refinement proofs**
+
+**Goal:** **L2/L3** theorems: `eval env f args fuel = …` ↔ your **`Prop`** / functional spec.
+
+**Tasks**
+
+- **Registration (`verify_registration_proof`)**: prove equivalence between **bytecode `eval`** result and **`verifyRegistrationProofProp`** (or `execVerifyRegistrationProof`) under explicit **fuel** and **parsing-success** side conditions — reusing [`Operational.lean`](lean/AptosFormal/Experimental/ConfidentialAsset/Registration/Operational.lean) / [`VerifyMath.lean`](lean/AptosFormal/Experimental/ConfidentialAsset/Registration/VerifyMath.lean).
+- **`confidential_balance`**: lemmas that homomorphic ops match **Twisted ElGamal** specs in Lean (may require **`AptosFormal`** specs for `ristretto255_twisted_elgamal` parallel to Move).
+- **`confidential_proof`**: sigma + range proof **verification** as logical implications from native return + structured inputs.
+- **`confidential_asset`**: only after **L4** or **stubbed** store — prove **local** helpers first.
+
+**Exit criteria**
+
+- No **unintended** `sorry` in shipped modules; `#print axioms` reviewed for each top-level theorem.
+
+---
+
+### Workstream F — **Global / resource semantics (L4, optional track)**
+
+**Goal:** Model enough of **storage**, **`signer`**, and **FA** to state theorems about **`public entry fun`** behavior.
+
+**Tasks**
+
+- Extend `MoveValue` / `State` with a **minimal** resource map (type-indexed or monomorphic per milestone).
+- Implement **`borrow_global`**, **`move_to`**, **`exists`**, … as in [`file_format.rs`](https://github.com/aptos-labs/aptos-core/blob/main/third_party/move/move-binary-format/src/file_format.rs) / interpreter — **large**.
+- Integrate **dispatchable FA** behavior used by deposits/withdrawals or **prove** only **internal** `fun` paths that take pre-loaded references.
+
+**Exit criteria**
+
+- At least one **entrypoint**-level theorem **or** a published **negative result** (“we verify `foo_internal` only”) with clear scope.
+
+---
+
+## 6. Phased roadmap (milestones)
+
+### Phase 0 — Inventory and proof obligations (2–4 weeks, ongoing)
+
+**Deliverables**
+
+- Call graph: CA modules → natives → stdlib.
+- Table: function → **verification level target** (L0–L5) → owner.
+- List of **goldens** (Move tests) to become difftest oracles.
+
+**Partial (tree today):** registration FS `msg` + tagged SHA3-512 goldens as **hex corpora** with **`cargo run -p move-lean-difftest -- verify-corpora`** (Rust SHA3-512 cross-check vs Lean `TranscriptAlignment`) under [`difftest/corpora/confidential_assets/`](difftest/corpora/confidential_assets/).
+
+**Overlap (difftest track):** the **VM↔Lean inventory** and methodology for CA live under [`difftest/INVENTORY.md`](difftest/INVENTORY.md) and [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md) — extend the formal-plan tables from there or merge in a future edit.
+
+**Dependencies:** none.
+
+---
+
+### Phase 1 — CA difftest harness + one golden (4–8 weeks)
+
+**Deliverables**
+
+- New difftest suite: **one** `public` or `public(friend)` function with **minimal** natives (e.g. a **balance** serializer or a **no-op** path).
+- Lean runner + **one** committed or CI-generated oracle.
+
+**Dependencies:** Workstream D; minimal B from **existing** instructions.
+
+**Success:** CI runs VM + Lean on CA package.
+
+**Status (tree today):** Multiple CA-related harness suites and **merged e2e** oracle paths are already wired (see **§2.1**); Phase 1 is **superseded for “existence of a suite”** — remaining Phase 1-style work is **§4.5 checklist depth** (non-witness Lean rows, corpora, `deserialize_*` `Some`, …) on the differential plan.
+
+---
+
+### Phase 2 — `ristretto255_twisted_elgamal` + `confidential_balance` (8–16 weeks)
+
+**Deliverables**
+
+- Native/spec coverage for **twisted ElGamal** operations used by balance.
+- Bytecode transcription for **selected** `public fun` in `confidential_balance` (e.g. chunk split, encrypt-with-identity-randomness helpers if bytecode-heavy).
+- Difftest goldens for those functions.
+- **Refinement** for “plaintext chunk vector ↔ ciphertext” for **fixed** small cases, then generalize.
+
+**Dependencies:** A (crypto), B/C, D, E.
+
+---
+
+### Phase 3 — `confidential_proof` (16+ weeks, parallelizable by sub-proof)
+
+**Sub-phases**
+
+3a. **Registration bytecode** (`verify_registration_proof`): transcription + natives + difftest + refinement to **existing L0** spec.  
+3b. **Withdraw / normalize / key rotation** proofs: same pattern.  
+3c. **`verify_transfer_proof`**: largest (sigma + Bulletproofs); consider **proof-modular** lemmas (verify sigma subroutine ↔ spec).
+
+**Dependencies:** Phase 2; full A for crypto.
+
+---
+
+### Phase 4 — `confidential_asset` (depends on Phase 3 or stubbed proof calls)
+
+**Deliverables**
+
+- Internal `fun` verification where possible **without** L4.
+- **L4** track: entry `confidential_transfer`, `deposit_to`, `withdraw_to`, … with **explicit** store axioms or modeled store.
+
+**Dependencies:** Phase 3 + F if entrypoints required.
+
+---
+
+### Phase 5 — Hardening and regression
+
+**Deliverables**
+
+- **Upgrade playbook**: when Move or compiler changes, regenerate disassembly, rerun difftest, re-check `sorry`.
+- Extend **golden consistency** scripts if CA bytes are duplicated in Lean ([`check_golden_consistency.sh`](check_golden_consistency.sh) pattern).
+
+---
+
+## 7. Risks and mitigations
+
+| Risk | Mitigation |
+|------|------------|
+| Bulletproofs / range proofs too heavy to spec in Lean | Start **oracle-only** for native return; prove **simpler** lemmas; or bound scope to “native agrees with Rust reference impl” tested by difftest. |
+| Proof effort explodes | **Per-function** milestones; keep **L0** specs as the contract. |
+| Global FA semantics | Default to **L2 internal fun** first; document **L4** as stretch. |
+| Compiler drift | Pin **toolchain + commit** in transcription headers; CI difftest. |
+
+---
+
+## 8. “Done” checklist (organization-level)
+
+Use this as a **release gate** for claiming “CA is formally verified” at a given level:
+
+- [ ] **Scope document**: which **functions** and which **level (L0–L5)** per function.
+- [ ] **No undocumented `sorry`** in production Lean modules for claimed theorems.
+- [ ] **`#print axioms`** reviewed and listed (including **`ristretto_subgroup_order_prime`**-style custom axioms).
+- [ ] **Difftest** covers every **transcribed** function on representative inputs (or explains why not).
+- [ ] **REGISTRATION_VERIFY_REVIEW** (or successor) updated to describe **bytecode refinement** if L2+ shipped for registration.
+- [ ] **Move/README.md** updated: which **globals** / **natives** are supported for CA.
+
+---
+
+## 9. Summary
+
+Formal verification of **all** confidential assets is a **multi-year**, **multi-workstream** effort if interpreted as **bytecode-level refinement + difftest + eventual storage**. The **feasible** path is:
+
+1. **Keep and extend L0** (already strong for registration math).  
+2. **Add CA difftest** and **grow natives + bytecode** from **twisted ElGamal** and **`confidential_balance`** upward.  
+3. **Prove refinement** incrementally toward **`verify_registration_proof`**, then **other proof verifiers**, then **`confidential_asset`** with an explicit decision on **L4**.
+

+# Confidential assets — Move source audit notes (formal / difftest track)
+
+**Audience:** Engineers and proof engineers working on `AptosFormal`, `move-lean-difftest`, and CA alignment.
+
+**Scope:** Targeted review of `aptos_experimental::confidential_*` and related `aptos_std` crypto helpers while extending formal artifacts. This is **not** a substitute for Aptos product security review, external audit, or bug bounty triage.
+
+**Method:** Static reading of Move sources on disk in this repo revision; no claimed completeness.

+
+## Summary
+
+| ID | Severity | Topic |
+|----|----------|--------|
+| **M1** | Informational (API / semantics) | `deserialize_*` returns `Some` without validating Bulletproofs wire bytes |
+| **M2** | Documentation (resolved) | `new_scalar_from_tagged_hash` / `new_scalar_from_sha3_512` now **`assert!` + `extract`** (`confidential_proof.move`) |
+| **M3** | Informational (precondition) | `#[test_only]` / harness provers use `scalar_invert(..).extract()` — aborts if scalar is non-invertible |
+| **M4** | Informational (harness) | `confidential_gas_e2e_helpers` parses auditor pubkeys with `.extract()` — malformed test inputs abort |
+| **M5** | Informational (abort semantics / UX) | Production **`entry`** paths (e.g. `confidential_transfer`) chain `option::extract()` on balance / auditor / proof deserializers — **malformed client payloads abort** the transaction (safe rejection), not silent state corruption |
+| **M6** | Documentation (resolved) | Doc typo **`suffucient`** on `ensure_sufficient_fa` — fixed to **sufficient** (`confidential_asset.move`) |
+| **M7** | Documentation (resolved) | Awkward phrasing **“decrypt the it”** on `confidential_transfer` — fixed (`confidential_asset.move`) |
+| **M8** | Informational (API naming) | Public function **`new_pending_balance_u64_no_randonmess`** — spelling typo (**randonmess** vs **randomness**); renaming would be a **breaking** API change, so it is documented here rather than “fixed” in-place |
+| **M9** | Informational (API / wire semantics) | **`serialize_auditor_amounts`** concatenates `balance_to_bytes` in **vector order**; permuting the `vector` changes the wire when encodings differ (difftest **120** vs **121** + Lean `serializeAuditorAmounts_mixed512_orders_distinct`; **122** vs **123** + `serializeAuditorAmounts_mixed768_orders_distinct`). Integrations that map auditors to indices must keep the same ordering as Move. |
+| **M10** | Informational (wire ambiguity) | If every serialized ciphertext byte is **zero**, different **`ConfidentialBalance`** sequences can still yield the **same** overall `vector` (e.g. `[pending_zero, actual_zero]` vs `[actual_zero, pending_zero]` are both **768** bytes of zeros on the current VM). Off-chain tools cannot recover per-slot **pending vs actual width** from raw bytes alone without out-of-band typing. |
+| **M11** | Informational (formal / difftest alignment) | VM **`deserialize_*` → `Some`** layout rows vs Lean **length-only** bytecode (**110–113**, same **`Step`** as **128–130**); see **§ M11** below and **`STUB_POLICY.md`**. |
+
+**No production-breaking cryptographic flaw was identified in this pass** from the slices above; the items are documentation of **semantics**, **hardening opportunities**, and **test-only / harness** sharp edges.
+
+---
+
+## M1 — `deserialize_*` vs `range_proof_from_bytes` (API semantics)
+
+**Locations**
+
+- `aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move` — `deserialize_withdrawal_proof`, `deserialize_transfer_proof`, `deserialize_normalization_proof`, `deserialize_rotation_proof`.
+- `aptos-move/framework/aptos-stdlib/sources/cryptography/ristretto255_bulletproofs.move` — `range_proof_from_bytes` wraps arbitrary `vector` in `RangeProof` without parsing or rejecting malformed proofs.
+
+**Observation**
+
+`deserialize_*_proof` returns `option::some` whenever the **sigma** sub-deserializer succeeds. The ZK range proof slots are filled via `range_proof_from_bytes`, which **does not** establish cryptographic validity.
+
+**Why this is not automatically a protocol vulnerability**
+
+Soundness for transactions still depends on **`verify_*`** entry paths (and Bulletproofs / Ristretto natives inside them), which perform real verification. `deserialize_*` is better read as **layout / typing** of bytes into structs.
+
+**Risk if misunderstood**
+
+Off-chain tooling or future call sites might treat `Some` as “safe to use in a verify-free path.” That would be incorrect.
+
+**Formal / difftest alignment**
+
+Difftest documents Lean witness limits for VM↔Lean on `deserialize_*`; hex corpora under `difftest/corpora/confidential_assets/deserialize_sigma_*.hex` pin **sigma wire** layouts only. For **`test_deserialize_*_layout_ok_is_some`**, see **M11** (Lean **`ldTrue`** stubs vs VM real parsers). Separate rows **`test_layout_sigma_*_byte_length_is_*`** (**Lean 128–130**) exercise **`vecLen` + `eq`** on the same pinned sigma bytes — length agreement only, not parser replay.
+
+---
+
+## M2 — `new_scalar_from_tagged_hash` / `new_scalar_from_sha3_512` (`option::extract`) — **addressed**
+
+**Location:** `confidential_proof.move` — `new_scalar_from_tagged_hash`, `new_scalar_from_sha3_512`.
+
+**Observation (historical)**
+
+Previously both used `option::extract` on `ristretto255::new_scalar_uniform_from_64_bytes` without an immediately adjacent `assert!(option::is_some(&...))`.
+
+**Resolution**
+
+Both paths now **`assert!(option::is_some(&sc_opt), error::invalid_argument(ESIGMA_PROTOCOL_VERIFY_FAILED))`** before **`option::extract`**, so the **64-byte** precondition is explicit if implementations change.
+
+**Analysis (unchanged)**
+
+`ristretto255::new_scalar_uniform_from_64_bytes` returns `some` **iff** the input vector has length **64** (`ristretto255.move`). `tagged_hash` and `aptos_hash::sha3_512` outputs are **64 bytes** on these paths, so `none` remains **unreachable** under current implementations.
+
+---
+
+## M3 — `scalar_invert(..).extract()` in `#[test_only]` provers
+
+**Locations (examples)**
+
+- `confidential_proof.move` — `prove_withdrawal`, `prove_transfer`, `prove_normalization`, `prove_rotation`, etc. (all `#[test_only]`).
+
+**Observation**
+
+Prover-side code uses `ristretto255::scalar_invert(dk).extract()` (and similar). `scalar_invert` returns `none` for a **zero** scalar (`ristretto255` tests document this).
+
+**Impact**
+
+Test / harness code **aborts** if a caller passes a zero decryption key (or other non-invertible scalar where applicable). This is **not** a production `public`/`entry` path in the snippets reviewed; it affects **test-only proof generation**.
+
+**Recommendation**
+
+Test harnesses should pass invertible scalars; optional explicit `assert!(option::is_some(&ristretto255::scalar_invert(dk)), …)` improves error messages over a bare `extract` abort.
+
+---
+
+## M4 — `confidential_gas_e2e_helpers` auditor pubkey parsing
+
+**Location:** `confidential_gas_e2e_helpers.move` — `pack_confidential_transfer_proof_with_auditors` (and similar loops).
+
+**Observation**
+
+`twisted_elgamal::new_pubkey_from_bytes(auditor_eks[i]).extract()` is used without a per-element `is_some` check.
+
+**Impact**
+
+**Test-only / e2e helper** module: malformed auditor key bytes cause **abort** during packing, not a silent wrong proof. Production entrypoints still run full `verify_transfer_proof` with real crypto.
+
+**Recommendation**
+
+For clearer harness failures, prefer `assert!(option::is_some(&pk), …)` with a descriptive error code before `extract`.
+
+---
+
+## M5 — Production `entry` functions and `option::extract`
+
+**Location:** `confidential_asset.move` — e.g. `confidential_transfer` (`new_*_from_bytes`, `deserialize_auditor_*`, `deserialize_transfer_proof`, all `.extract()`).
+
+**Observation**
+
+Several **public entry** functions deserialize caller-supplied bytes and use **`option::extract`** (via `extract()` on `Option`) without an intermediate local and `assert!` with a module-specific error code on every `none` case in the same syntactic pattern (some paths use `assert!` earlier inside helpers).
+
+**Security read**
+
+For malformed proofs / balances / auditor blobs, the typical outcome is **`abort`** (transaction failure), which is **safe** for on-chain state: invalid data does not silently pass verification.
+
+**Operational read**
+
+This is mostly **UX / observability** (clients see a failed transaction; error mapping depends on abort vs structured `error::` paths elsewhere). It is **not** framed here as a soundness vulnerability.
+
+---
+
+## M8 — `new_pending_balance_u64_no_randonmess` (spelling)
+
+**Location:** `confidential_balance.move` — `public fun new_pending_balance_u64_no_randonmess`.
+
+**Observation**
+
+The identifier uses **randonmess** instead of **randomness**. This is a **public** API surface; fixing the spelling would require a new function name (and deprecation of the old one) to avoid breaking callers.
+
+**Impact**
+
+None for correctness or security; **documentation / ergonomics** only.
+
+---
+
+## M9 — `serialize_auditor_amounts` follows vector order
+
+**Location:** `confidential_asset.move` — `public fun serialize_auditor_amounts`.
+
+**Observation**
+
+The output is a concatenation of per-balance encodings in **`amounts` vector order**. Swapping two non-identical balances (for example zero pending vs **`u64(1)`** no-rand pending) yields a **different** **512**-byte wire. For **768**-byte mixed **actual** + **`u64(1)`** pending rows, reversing vector order changes the byte layout (difftest **122** / **123**); see **M10** for the degenerate all-zero case.
+
+**Impact**
+
+**Not a protocol flaw** — it is the natural encoding. Off-chain code that re-sorts auditor balances or merges lists without preserving on-chain order can produce **unintended** auditor wires relative to what signers / auditors expect. Difftest and Lean (`serializeAuditorAmounts_mixed512_orders_distinct`) document the distinction.
+
+---
+
+## M10 — All-zero encodings can collide across different balance shapes
+
+**Location:** `confidential_asset.move` — `serialize_auditor_amounts`; `confidential_balance.move` — `balance_to_bytes`.
+
+**Observation**
+
+`balance_to_bytes` for **pending** zero and **actual** zero (no randomness) produces only **zero** ciphertext bytes on the current VM. Concatenating **256** + **512** in either order therefore yields the same **768**-byte all-zero `vector` for `[pending_zero, actual_zero]` and `[actual_zero, pending_zero]`.
+
+**Impact**
+
+**Not an on-chain ambiguity** for honest modules that deserialize with typed `new_*_from_bytes` length checks. It **is** a footgun for **off-chain** tooling that tries to infer “which slice was pending vs actual” from raw bytes without metadata. Difftest **122**/**123** intentionally use a **non-zero** pending encoding (`u64(1)` no-rand) so VM↔Lean corpora remain byte-order-sensitive.
+
+---
+
+## M11 — Lean column for `deserialize_*` layout-`Some` rows (length check, not parser replay)
+
+**Locations:** `AptosFormal.Move.Programs.Confidential` (function indices **110–113**); `AptosFormal.DiffTest.Runner` name mappings; `difftest/src/suites/confidential_proof.rs` harness.
+
+**Observation**
+
+The VM runs real **`confidential_proof::deserialize_*`** on fixed sigma bytes and returns **`option::is_some(&…)`**. The Lean column uses the same bytecode as indices **128–130**: **`ldConst`** (corpus-matching sigma bytes) + **`vecLen`** + **`eq`** against **1152** / **1216** / **1792**, so **`lake exe difftest`** checks a **necessary** layout-length condition (still **not** Bulletproofs slots, Ristretto batch parsing, or friend-module internals in `Move.eval`).
+
+**Related**
+
+Indices **128–130** are the explicitly named harness tests for the same length property; **110–113** align the **`layout_ok_is_some`** oracle rows with that **`Step`** instead of a context-free **`ldTrue`**. Transfer **auditor extension** tiers (**131**/**132** through **151**/**152**) pair **`test_layout_sigma_transfer_*_byte_length_is_*`** with **`test_deserialize_transfer_layout_extended_*_ok_is_some`**: Lean uses **`ldConst` 27**–**37** + **`vecLen`** + **`eq`** on **1920** … **3200** B corpus bytes (one tier per **`ldConst`**); the second index in each pair duplicates the first bytecode (VM-only stronger **`deserialize_transfer`** `Some`).
+
+**Why this is documented**
+
+Lean’s length check can **diverge** from the VM if **`deserialize_*`** later rejects wires that still have the nominal sigma length. **L0** lemmas relate checked-in **`deserialize_sigma_*.hex`** bytes to **`serialize_auditor_eks_*_a_points.hex`** prefixes (**`deserializeSigma*…_five/six_points_eq_serializeAuditorEks*`** in `Confidential.lean`) without claiming full parser parity.
+
+---
+
+## Positive checks (no issue filed)
+
+- **`register`** (`confidential_asset.move`) invokes `confidential_proof::verify_registration_proof` **before** `register_internal`, with chain id, addresses, and Fiat–Shamir transcript inputs wired consistently in the reviewed block.
+- **Bulletproofs DST length:** `verify_range_proof` enforces `dst.length() <= 256` (`ristretto255_bulletproofs.move`); CA DST string is shorter — domain separation is enforced where documented.
+
+---
+
+## Maintenance
+
+When CA Move sources change behavior relevant to formal work:
+
+1. Update this file if new **verified** observations appear.
+2. Keep **[`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md)** §4.5 / inventory rows aligned with what the formal tree actually claims.
+3. Distinguish **“API hazard / hardening”** from **“soundness break”** — only the latter belongs in urgent security channels without additional review.

+### 6.3a Bytecode transcription and eval smoke tests (L2)
+
+**What Lean provides today.**
+
+- **Transcribed bytecode** (`AptosFormal.Move.Programs.Registration`): an **83-instruction** `MoveInstr` array faithfully transcribed from the **`movement` v7.4.0** compiler output (`movement move disassemble`, def_idx 39, PC 0–82). Local layout: 7 parameters (chain_id, sender, contract_address, ek, token_address, commitment_bytes, response_bytes) + 12 temporaries (19 locals total). The transcription uses reference-semantic instructions (`immBorrowLoc`, `mutBorrowLoc`) matching the compiler output exactly.
+
+- **Oracle-parameterized natives** (`AptosFormal.Move.Native.Registration`): `RegistrationNativeOracle` bundles Ristretto point operations, scalar parsing, pubkey wire conversions, and twisted ElGamal helpers. Crypto-ops use `FuncBody.nativeRef` (receiving `ContainerStore` + `List MoveValue` and returning `Option (List MoveValue × ContainerStore)`) with a `derefImm` helper that transparently handles both immutable references (`.immRef id` → container store lookup) and direct values (pass-through). Non-oracle natives (SHA3-512, tagged hash, BCS, Option is_some/extract, vector append/singleton) use `FuncBody.native` and are **executable** in Lean (no oracle).
+
+- **Module environment** (`registrationModuleEnv`): 18-slot function table (indices 0–9 oracle `nativeRef`, 10–16 executable `native`, 17 bytecode verifier). Constant pool entry 0 is the `FIAT_SHAMIR_REGISTRATION_SIGMA_DST` bytes.
+
+- **Eval smoke tests** (`…Registration.BytecodeSmoke`): `native_decide` proofs that `eval` on golden inputs (with **reference args**: `.immRef 0` for ek and a pre-populated `MachineState`) produces `returned []` (valid proof) and `aborted 65537` (invalid proof). These run the full evaluator loop (200 fuel steps) through all 83 instructions with container-store threading.
+
+- **MachineState projection** (`ExecResult.dropMs` in `EvalEquiv.lean`): The 83-instruction bytecode populates the `ContainerStore` via `immBorrowLoc`/`mutBorrowLoc`/`nativeRef` calls, so `eval` returns `.returned [] ms` where `ms` has a non-empty container store. The functional simulation returns `.returned [] MachineState.empty`. `ExecResult.dropMs` projects away the `MachineState` from `.returned` outcomes (replacing with `MachineState.empty`), enabling comparison of observable results (return values / abort codes) while abstracting over the differing container stores. Includes `@[simp]` lemmas and bidirectional `_iff` lemmas for all constructors.
+
+- **Refinement theorems** (`…Registration.Refinement`):
+  - `func_success_implies_exec_some` — **proven (no sorry)**: if the bytecode-level functional sim returns successfully, the spec-level runner also returns `some ()`. Uses `OracleCoherence` (both forward and reverse properties), `func_success_extracts` (structural decomposition of the 15-layer nested match), and `buildFSMessageMv_list_gen` (message coherence through `ByteArray.toList_append`).
+  - `func_abort_implies_exec_none` — **proven (no sorry)**: if the functional sim aborts, the spec-level runner returns `none`. Uses `func_abort_classification` (3-way abort decomposition) + failure-direction `OracleCoherence` properties (`compressedFromBytes_false_rev`, `scalarFromBytes_false_rev`).
+  - `eval_success_implies_prop` — **composition proven (no sorry in proof body)**: composes `eval_eq_func` (via `.dropMs`) + `func_success_implies_exec_some` + `execVerifyRegistrationProof_iff`. Accepts any returned `MachineState` `ms` (not just `MachineState.empty`), since the real bytecode leaves references in the container store. Depends on `eval_eq_func` (sorry in `eval_eq_func_100`) for the L2≡L1.5 step.
+  - `eval_abort_implies_not_prop` — **composition proven (no sorry in proof body)**: composes `eval_eq_func` (via `.dropMs`) + `func_abort_implies_exec_none` + `execVerifyRegistrationProof_iff`. The `.aborted` constructor doesn't carry `MachineState`, so `.dropMs` is trivial. Depends on `eval_eq_func` (sorry in `eval_eq_func_100`).
+  - `eval_eq_func` — **largely proven**: lifts `eval_eq_func_100` (at fuel 200) to arbitrary `fuel ≥ 200` via `eval_fuel_ge_dropMs`. Uses `by_cases` on whether `eval` at fuel 200 is `.error`. **One residual sorry** for error-fuel-monotonicity: when the oracle returns garbage (both sides are `.error`), proving `eval fuel = .error` from `eval 200 = .error` requires bounded-execution-length formalization. This case is vacuous for all callers (which assume `eval` returns `.returned` or `.aborted`).
+  - `eval_eq_func_100` — **sorry** (in `EvalEquiv.lean`): states that `(eval ... 200 MachineState.empty).dropMs = verifyRegistrationBytecodeResult ...` for all abstract oracles, using **value args** (struct for ek, not `.immRef`). The `nativeRef` wrappers handle non-ref values via `derefImm` (pass-through). Proving this requires symbolic bytecode stepping through 83 instructions with container-store threading. Concrete instances verified by `native_decide` in `BytecodeDifftestEval.lean`.
+
+- **Functional simulation** (`…Registration.FunctionalSim`): `verifyRegistrationBytecodeResult` — a readable Lean function on `MoveValue`s that mirrors the bytecode's control flow, returning `MachineState.empty` in all cases. Serves as the L1.5 intermediary: `eval ≡ L1.5` is verified by `native_decide` on concrete oracles (via `.dropMs`); `L1.5 ≡ L1` is algebraic under oracle coherence. Includes `func_trichotomy`, `buildFSMessageMv` (Fiat-Shamir message construction), `buildFSMessageMv_list` and `buildFSMessageMv_list_gen` (message correctness proven, no sorry). `ByteArray.toList_append` is axiomatized as a library-level obligation (verified concretely by `native_decide` for every tested ByteArray pair; orthogonal to the cryptographic verification).
+
+- **Concrete refinement chain** (`…Registration.BytecodeDifftestEval` + `…Registration.BytecodeDifftestBridge`): **Four independent oracle traces** with `native_decide` proofs in two categories:
+
+  *Smoke tests* (reference args + populated `MachineState`, testing `eval` directly):
+  - Trace 1 (dk=42/k=9999, chainId=9, @0x1/@0x2/@0x3): eval success (1 proof).
+  - Trace 2 (chainId=42, @0x10/@0x20/@0x30, basepoint ek/R): eval success + eval abort (bad commitment) (2 proofs).
+  - Trace 3 (scalar-stage abort): eval abort with scalar `optionIsSome` false (1 proof).
+  - Trace 4 (point-equality-false abort): eval abort with `pointEquals` false (1 proof).
+
+  *Func≡eval tests* (value args + `MachineState.empty` + `.dropMs`, testing `eval` vs `verifyRegistrationBytecodeResult`):
+  - Trace 1: `func_eq_eval_difftest_val` (func=eval via `.dropMs`) + `func_difftest_returns` (func returns `[]`) (2 proofs).
+  - Trace 2: `func_eq_eval_trace2_val` (func=eval) + `func_trace2_returns` (func returns `[]`) + `func_trace2_aborts` (func aborts on bad commitment) + `func_trace2_scalar_aborts` (func aborts on bad scalar) + `func_trace2_pointeq_false_aborts` (func aborts on point inequality) (5 proofs).
+
+  - `BytecodeDifftestBridge` composes trace 1 into `difftest_L2_implies_L0` (no sorry), proving the full L2 → L0 chain.
+
+- **Difftest honest L1 column** (`caRegistrationBytecodeEvalNative` at index 194 in `confidentialModuleEnv`): wraps `eval` + `registrationModuleEnv` with the concrete difftest oracle, mapped in `RunnerFuncMappingAux` as `test_registration_bytecode_eval_roundtrip`. This enables cross-checking the Lean bytecode evaluator against the Rust VM in the difftest matrix.
+
+- **L4 entry-point stub** (`…Registration.RegisterEntryStub`): `registerEntrySpec` models the `register` entry function as parse-ek + verify-proof + store. Two proven theorems: `register_success_implies_verify_success` (success implies the embedded proof verification returned) and `register_success_stores_ek` (stored ek matches input bytes). No `sorry`.
+
+**What remains.**
+
+1. **`eval_eq_func_100` (L2 ≡ L1.5, abstract) — sorry.** The theorem states `(eval ... 200 MachineState.empty).dropMs = verifyRegistrationBytecodeResult ...` for all abstract oracles. Proving this requires symbolic stepping through 83 instructions with container-store threading (each `immBorrowLoc`/`mutBorrowLoc` allocates in the `ContainerStore`; each `nativeRef` call reads/writes). Concrete instances are verified by `native_decide` for 4 independent oracle traces. The `EvalEquiv.lean` file contains `@[simp]` fusion lemmas (`match_single?`, `bind_single?`, `match_match_some_single_none`, `runStep_handleNativeResult_ret1/ret0`) and `runStep` machinery designed for the symbolic proof, but the full `simp` + `split` proof is not yet completed due to term-size from container-store threading.
+2. **Error-fuel-monotonicity sorry in `eval_eq_func`.** When `eval` at fuel 200 returns `.error` (oracle returns garbage), lifting to arbitrary `fuel ≥ 200` requires proving `eval fuel = .error` for the `.error` case. This sorry is **vacuous for all callers** (`eval_success_implies_prop`, `eval_abort_implies_not_prop`) since they assume `eval` returns `.returned` or `.aborted`.
+3. **`ByteArray.toList_append`/`ByteArray.toList_mk_singleton` axioms.** Library-level obligations for `ByteArray.toList` distributivity. Both are concretely verified by `native_decide` for every tested pair. A proper proof requires a loop invariant on the irreducible `ByteArray.toList.loop`. This is orthogonal to the cryptographic claims.
+
+---
+
+### 6.3d Bytecode disassembly cross-check (compiler output vs Lean transcription)
+
+**Goal.** Verify that the hand-transcribed `MoveInstr` array in `AptosFormal.Move.Programs.Registration` faithfully represents the actual bytecode produced by the production compiler for `verify_registration_proof`.
+
+**Method.** Compiled `aptos-experimental` with `movement` v7.4.0 (`movement move compile --package-dir aptos-move/framework/aptos-experimental --named-addresses "aptos_experimental=0x1"`), then disassembled the output (`movement move disassemble --bytecode-path .../confidential_proof.mv`). The disassembly lives at `aptos-move/framework/aptos-experimental/build/AptosExperimental/bytecode_modules/confidential_proof.mv.asm`, lines 4811–4914, function definition index 39.
+
+#### Current status: faithful 83-instruction transcription
+
+The Lean transcription now contains **83 instructions** (PC 0–82) with **19 locals** (7 params + 12 temporaries), matching the compiler output **instruction-for-instruction** including all reference-semantic instructions (`immBorrowLoc`, `mutBorrowLoc`), abort blocks, and temporary variables. The `registrationModuleEnv` uses `FuncBody.nativeRef` for crypto operations that receive references in the real bytecode, and `FuncBody.native` for pure operations (BCS, vector, Option, SHA3-512).
+
+#### Previous state (archived divergence analysis)
+
+The original §6.3d analysis documented 10 divergence types (D1–D10) between a previous 67-instruction value-semantics abstraction and the 83-instruction compiler output. That analysis remains valid as historical documentation of *why* the value-semantics abstraction was behavior-preserving, but is no longer the current Lean code.
+
+The retranscription to 83 instructions was motivated by the need to:
+1. Eliminate the manual behavior-preservation argument (D1–D10) by matching the compiler output exactly.
+2. Enable `native_decide` proofs that run `eval` on the real bytecode with reference arguments (verified in `BytecodeSmoke.lean`).
+3. Support the `nativeRef` native function calling convention (receiving `ContainerStore` for reference dereferencing).
+
+#### MachineState abstraction via `ExecResult.dropMs`
+
+The 83-instruction bytecode, due to `immBorrowLoc`/`mutBorrowLoc`/`nativeRef` calls, populates the `ContainerStore` during execution. After `eval` completes, the returned `MachineState` contains allocated reference entries that are semantically irrelevant (all references are local to the function and never escape). The functional simulation (`verifyRegistrationBytecodeResult`) returns `MachineState.empty`.
+
+`ExecResult.dropMs` (defined in `EvalEquiv.lean`) bridges this gap by projecting `.returned vs ms` to `.returned vs MachineState.empty`, enabling comparison of observable outcomes:
+- **Success**: same return values (`[]` for void return)
+- **Abort**: same abort code (`65537`)
+- **Error**: same `.error` (oracle returns garbage)
+
+This is a weaker claim than full `MachineState` equality but is **sufficient for the refinement chain**: the L1.5→L1→L0 layers only inspect return values and abort codes, never the final container store.
+
+#### Constant pool
+
+The compiler's constant pool index 5 contains the BCS-serialized DST vector: `[38, 77, 111, ...]` (38 = ULEB128 length prefix, then 38 bytes of `"MovementConfidentialAsset/Registration"`). The Lean model's constant pool index 0 stores the deserialized `MoveValue.vector .u8 [77, 111, ...]`. The VM deserializes constants at load time, so these are equivalent: `LdConst` pushes the same 38-byte vector onto the stack in both cases.
+
+#### Summary
+
+The Lean bytecode array is a **faithful 83-instruction transcription** of the `movement` v7.4 compiler output for `verify_registration_proof`, including all reference-semantic instructions. The `ExecResult.dropMs` projection abstracts over the `MachineState` difference (populated `ContainerStore` vs empty) that arises from reference operations, enabling comparison of observable outcomes (return values / abort codes). This observable-outcome equivalence is:
+- **Verified by `native_decide`** for 4 independent concrete oracle traces (7 func≡eval proofs in `BytecodeDifftestEval.lean`).
+- **Stated for all abstract oracles** in `eval_eq_func_100` (sorry — requires symbolic stepping through 83 instructions with container-store threading).
+- **Sufficient for the full refinement chain** (L2→L0), since downstream layers only inspect return values and abort codes.

+# Difftest inventory & methodology (Phase 0)
+
+This document is the **hub** for planning and extending **Move VM ↔ Lean** differential tests (`move-lean-difftest` + `lake exe difftest`). It applies to **any** Move package you later wire into the harness (stdlib wrappers, framework modules, confidential assets, …).
+
+## 1. Source of truth — tests are allowed to fail
+
+- The **JSON oracle** is produced by running the **real Move VM** (Rust) on concrete inputs. Those outputs are treated as **ground truth for that run**.
+- The **Lean** side **re-computes** the same case using `AptosFormal.Move` and **compares** to the oracle.
+- **If Move code is wrong** but Lean matches a *correct* spec, the VM oracle will still record what Move *actually* did — a **later** Lean change to match buggy Move would show as “passing” while being wrong. The intended discipline is:
+  - **Independent** expectations for high-value cases (e.g. golden vectors from crypto reviews, or second tooling), **or**
+  - **Regression**: when you **intentionally fix** Move, the oracle **must be regenerated**; Lean should then match the **new** VM behavior — a **failure** before regen catches drift.
+- **If Lean is wrong** (transcription, missing instruction, wrong native), comparison **fails** — that is the point of difftest.
+
+Neither implementation is assumed correct **by construction**; agreement is **evidence** on the oracle set only.
+
+## 2. Suite registry (generic harness)
+
+- **Rust:** one implementation of `DiffTestSuite` per logical area; register in [`src/suites/mod.rs`](src/suites/mod.rs) (`all_suites` + `suites_filtered` match arms — **keep match arms in sync** with `all_suites()`).
+- **List ids:** `cargo run -p move-lean-difftest -- --list-suites` or `./aptos-move/framework/formal/difftest.sh --list-suites`.
+- **Lean:** extend `AptosFormal.DiffTest.Runner` (`funcNameToMapping` / case dispatch) and `Move` `ModuleEnv` / natives for each **new** function you add to an oracle.
+
+See [`README.md`](README.md) § *Adding coverage* for the file-level checklist.
+
+## 3. Inventory artifacts (Phase 0 deliverables)
+
+| Document | Purpose |
+| -------- | ------- |
+| [`STUB_POLICY.md`](STUB_POLICY.md) | Lean column: bytecode vs natives vs abstract globals (CA plan §3). |
+| [`inventory/README.md`](inventory/README.md) | Index of per-package inventories. |
+| [`inventory/confidential_assets.md`](inventory/confidential_assets.md) | **Confidential assets (experimental)** — public API surface, difftest mode per symbol, native/transitive deps. Independent vectors (checklist §4.3 iii): [`corpora/confidential_assets/README.md`](corpora/confidential_assets/README.md). |
+| [`inventory/confidential_native_matrix.md`](inventory/confidential_native_matrix.md) | **CA native / crypto matrix** — `aptos_std` Ristretto/BP/hash vs Lean status (FV plan Workstream A). |
+| [`inventory/move_framework_template.md`](inventory/move_framework_template.md) | Blank template for **other** Move framework packages. |
+
+## 4. Difftest modes (per function / case)
+
+Use these labels in inventory tables:
+
+| Mode | Meaning |
+| ---- | ------- |
+| **VM↔Lean** | Full differential: oracle from VM, Lean `eval` must match. |
+| **VM-only** | Oracle recorded from VM; Lean column **skipped** until model exists (document reason). |
+| **Blocked** | Cannot run in harness yet (missing compiler support, storage, …). |
+
+## 5. When you add a new suite (checklist)
+
+1. Add `src/suites/.rs` implementing `DiffTestSuite`.
+2. Register in `all_suites()` **and** the `suites_filtered` match in [`mod.rs`](src/suites/mod.rs).
+3. Run `cargo run -p move-lean-difftest -- --list-suites` and confirm the new id appears.
+4. Extend Lean `DiffTest` runner + `ModuleEnv` for each `TestCase` you emit.
+5. Add an **`inventory/.md`** row or standalone doc for long-term tracking.
+
+## 6. Related plans
+
+- Confidential assets **difftest-only** roadmap: [`../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md) (Phase 0 marked complete there with pointer here).
+- Full formal verification (refinement + globals): [`../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md).

+# JSON oracle changelog (`move-lean-difftest` → `lake exe difftest`)
+
+The Lean runner (`AptosFormal.DiffTest.JsonParser`) and the Rust harness (`schema.rs`) must stay in lockstep. When the JSON shape changes incompatibly:
+
+1. Bump `CURRENT_SCHEMA_VERSION` in `difftest/src/schema.rs`.
+2. Update the Lean parser and any `TestSuite` / `TestCase` structures as needed.
+3. Add a row below and regenerate committed or ignored oracle files.
+
+## Versions
+
+| Version | Date | Summary |
+|--------:|------|---------|
+| **1** | 2026-04-10 | Introduced `schema_version` (number) at suite root. Fields unchanged from prior informal format: `generator`, `module`, `test_cases` with `function`, `args`, `result` (`status` + `values` or `abort_code`). Older files without `schema_version` are accepted by Lean as `schemaVersion := none`. |
+
+**Tooling (not a schema bump):** `cargo run -p move-lean-difftest -- verify-corpora` — authoritative Rust **hex corpus** checks for confidential-assets goldens (registration DST, FS `msg` lengths, tagged SHA3-512 chain, Bulletproofs DST + digest, `deserialize_sigma_*.hex`, `serialize_auditor_*.hex`). CI and **`difftest.sh` \[0\]** use this command.
+
+**Compatible extension (still schema version 1):** optional per-case boolean **`skip_lean`**. When `true`, the Lean runner skips that row (VM-only oracle); omitted or `false` keeps VM↔Lean checks. Rust omits the field when `false` on serialize.
+

+## Policy
+
+- **Compatible** additions (optional fields, new `type` variants for typed values with backward parsing) do not require a version bump if Lean and Rust both accept old oracles.
+- **Incompatible** changes (renames, removed fields, changed `result` encoding) require a bump and a changelog entry.

+# Move ↔ Lean differential tests (`move-lean-difftest`)
+
+These tests compare the **real Move VM** (Rust) against the **Lean bytecode evaluator** on the same inputs and expected outputs. The Rust binary writes a **JSON oracle**; the Lean executable reads it and reports pass/fail.
+
+This is **runtime empirical checking**, not a formal proof. The oracle is **VM output** — if Move and Lean disagree, **something is wrong** (Move bug, Lean model bug, or stale oracle); do not assume confidential assets (or any module) is correct **a priori**.
+
+**Phase 0 inventory (planning, any future suite):** [`INVENTORY.md`](INVENTORY.md) and [`inventory/`](inventory/).
+
+## Git and CI
+
+**Registration + CA corpora (§4.5 / independent vectors):** [`corpora/confidential_assets/`](corpora/confidential_assets/) holds hex goldens for registration FS `msg`, tagged SHA3-512 digest, Bulletproofs `DST` + digest, **`deserialize_sigma_*.hex`** sigma wire layouts, and **`serialize_auditor_*.hex`** serializer pins. **Authoritative semantics** for CA behavior remain: (1) the **Move VM** when generating `difftest_oracle*.json`, and (2) **`lake exe difftest`** comparing that JSON to Lean `eval`. The corpus step is an extra **static** gate: length checks, recomputing SHA3-512 chains, and byte-for-byte comparisons against small fixed constants. That gate is implemented only in **Rust** (`cargo run -p move-lean-difftest -- verify-corpora`, also `#[test]` in `corpus_verify.rs`). **`../difftest.sh`** runs `verify-corpora` as step **\[0\]**; **`.github/workflows/formal-difftest.yaml`** does the same after the pinned toolchain. Move semantics notes: [`../CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md`](../CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md).
+
+**`difftest_oracle*.json` is gitignored** — it is generated output from the real VM, not source. Regenerate with `cargo run -p move-lean-difftest` (or `../difftest.sh`) before running `lake exe difftest`, or rely on a CI job that runs the harness then Lean in one pipeline.
+
+If you prefer **committed goldens** (offline Lean-only runs, PR diffs when VM output changes), remove the `difftest_oracle*.json` line from `difftest/.gitignore` and check the files in — trade-off is noisier PRs and risk of stale oracles.
+
+## Naming (not vector-specific)
+
+- **`difftest_oracle.json`** — default file holding VM ground truth for **all** registered suites (`vector`, `bcs`, `hash`, `global_resource_smoke`, `confidential_balance`, `confidential_elgamal`, `confidential_proof`, `confidential_asset`, `fa_stub`, or **`--suite confidential`** for the four confidential-related suites only). The old name `test_vectors.json` suggested everything was about `vector.move`; the new name matches “oracle for differential testing.”
+- **`schema_version`** — integer at the JSON root (`CURRENT_SCHEMA_VERSION` in Rust). Document incompatible bumps in [`ORACLE_CHANGELOG.md`](ORACLE_CHANGELOG.md).
+- **`skip_lean`** — optional per test case (`false` or absent = run Lean). Use `true` for VM-only rows when merging transactional e2e output into the same oracle file as VM↔Lean suites (Lean reports **SKIP** for those cases).
+
+**One JSON file (VM↔Lean + VM-only):** after you have a VM oracle from this crate and a separate fragment (full `TestSuite` or `{ "test_cases": [...] }`, e.g. exported from `e2e-move-tests`), merge them so Lean runs once:
+
+```bash
+# from repo root (input paths resolve via the difftest crate manifest, then cwd;
+# relative `-o` resolves against cwd when the parent directory exists, else the crate dir)
+cargo run -p move-lean-difftest -- merge -o difftest_merged.json \
+  aptos-move/framework/formal/difftest/difftest_oracle.json \
+  path/to/e2e_fragment.json
+cd aptos-move/framework/formal/lean && lake exe difftest ../difftest/difftest_merged.json
+```
+
+`merge` **preserves** each appended file’s `skip_lean` flags by default (use **`--force-skip-lean`** only if you want every appended row forced to VM-only). See **`cargo run -p move-lean-difftest -- merge --help`**.
+
+**CA transactional e2e → `OracleFragment`:** `e2e-move-tests` depends on this crate’s library types. The test **`export_confidential_asset_e2e_oracle_fragment`** runs all confidential-asset VM scenarios once and writes JSON when **`CONFIDENTIAL_ASSET_E2E_ORACLE_OUT`** is set to a file path. **Relative paths** are interpreted from the **workspace repo root** (two levels above `e2e-move-tests`’s `Cargo.toml`), so the recipe below works without an absolute path.
+
+```bash
+export CONFIDENTIAL_ASSET_E2E_ORACLE_OUT=aptos-move/framework/formal/difftest/difftest_ca_e2e_fragment.json
+RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests export_confidential_asset_e2e_oracle_fragment -- --test-threads=1
+```
+
+Then **`merge`** that file into the harness oracle and run **`lake exe difftest`** on the merged file (see **`.github/workflows/formal-difftest.yaml`** for the CI recipe).
+
+### CI parity: harness + CA e2e → merged Lean run
+
+**On PRs**, [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml) runs, in order: **`verify-corpora`** → VM harness (`cargo run -p move-lean-difftest -- --quiet`) → **`export_confidential_asset_e2e_oracle_fragment`** (writes `difftest_ca_e2e_fragment.json`) → **`merge`** into **`difftest_ci_merged.json`** → **`lake exe difftest`** on that merged file. You do **not** need to commit those JSON files: they are listed in [`difftest/.gitignore`](.gitignore); CI regenerates them whenever the workflow runs.
+
+**Locally** (same shape as CI, including export + merge — **slow** because the export test runs every CA e2e oracle scenario in `all_fragment_cases()`):
+
+```bash
+# From repo root
+DIFTEST_MERGE_CA_E2E=1 ./aptos-move/framework/formal/difftest.sh
+```
+
+Without `DIFTEST_MERGE_CA_E2E=1`, the script still runs **`verify-corpora`**, the VM harness, and Lean on **`difftest_oracle.json`** only (no e2e fragment, no merged file).
+
+### Checklist: adding a new CA transactional e2e oracle row
+
+Keep CI green when extending the VM↔Lean fragment:
+
+1. Add the scenario in [`../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs) and append it from **`all_fragment_cases()`**.
+2. Add a **`#[test]`** wrapper in [`../../e2e-move-tests/src/tests/confidential_asset_e2e.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e.rs) so `cargo test` exercises the harness path.
+3. Map the full oracle id in [`../lean/AptosFormal/DiffTest/RunnerFuncMappingAux.lean`](../lean/AptosFormal/DiffTest/RunnerFuncMappingAux.lean) (`funcIdx` + env flags).
+4. Record the extension in [`ORACLE_CHANGELOG.md`](ORACLE_CHANGELOG.md) and a row in [`inventory/confidential_assets.md`](inventory/confidential_assets.md).
+
+Then run **`DIFTEST_MERGE_CA_E2E=1 ./aptos-move/framework/formal/difftest.sh`** before landing if you changed Lean or need to reproduce CI locally.
+
+- **`difftest.sh`** — one-shot script at `formal/difftest.sh` (next to `lean/` and `difftest/`). It is **not** only for vector tests.
+
+The Move module **`0x1::difftest_vector`** is only the **vector** suite’s wrapper; BCS and hash use **`difftest_bcs`** and **`difftest_hash`**. Confidential-asset smoke modules: **`0x1::difftest_confidential_balance`**, **`difftest_confidential_proof`**, **`difftest_confidential_asset_layer`**.
+
+**`confidential_asset` and globals:** the Lean `Move.*` model has a **minimal global map**
+(`MachineState` + `GlobalResourceKey`; see [`STUB_POLICY.md`](STUB_POLICY.md) and
+[`../lean/AptosFormal/Move/README.md`](../lean/AptosFormal/Move/README.md)). It is **not**
+full Aptos `borrow_global` / FA / signer wiring. The **`confidential_asset`** suite still
+follows **Option B** from [`../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md): only **functions that need no globals**
+stay in the VM↔Lean oracle until bytecode + keys + policy are extended; FA-heavy
+entrypoints stay inventory-**Blocked** or move to Option C (VM-only column).
+
+**Transactional CA + real `verify_*` / `register` (VM only, not this JSON pipeline):** the repo already runs **`MoveHarness`** scenarios in **`e2e-move-tests`** (test-mode bytecode inject, FA + store, full proof paths). See plan [**§7.0**](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md). From repo root:
+
+```bash
+RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests confidential_asset_e2e -- --test-threads=1
+```
+
+**Native stubs vs bytecode (plan §3):** see **[`STUB_POLICY.md`](STUB_POLICY.md)** —
+obligations for bytecode, `MoveInstr`/`step`, and natives; confidential-suite tables;
+and how abstract globals relate to CA coverage.
+
+## Recommended: one command (all suites)
+
+From the repo root:
+
+```bash
+./aptos-move/framework/formal/difftest.sh
+```
+
+This runs `cargo run -p move-lean-difftest -- --quiet` then `lake exe difftest` on **`difftest/difftest_oracle.json`**.
+
+**Optional fuzz / property tests:** not part of this crate’s CI. Add a separate tool if you need random inputs beyond the fixed VM oracle vectors.
+
+## Run only one suite (e.g. BCS)
+
+Rust (from repo root):
+
+```bash
+cargo run -p move-lean-difftest -- --quiet --suite bcs
+```
+
+Writes **`difftest/difftest_oracle_bcs.json`** by default. Then:
+
+```bash
+cd aptos-move/framework/formal/lean
+lake exe difftest ../difftest/difftest_oracle_bcs.json
+```
+
+Or use the script (it picks the same default path as Rust when you pass `--suite`):
+
+```bash
+./aptos-move/framework/formal/difftest.sh --suite bcs
+```
+
+Multiple suites, sorted ids in the filename:
+
+```bash
+cargo run -p move-lean-difftest -- --quiet --suite hash --suite bcs
+# → difftest/difftest_oracle_bcs_hash.json
+```
+
+Override the path:
+
+```bash
+cargo run -p move-lean-difftest -- --quiet --suite bcs -o my_bcs.json
+```
+
+Use **`cargo run -p move-lean-difftest -- --help`** for the full CLI.

+## Prerequisites
+
+| Tool | Notes |
+| ---- | ----- |
+| **Cargo** | Build from the `aptos-core` repository root. |
+| **Lean + Lake** | Same setup as [`../lean/README.md`](../lean/README.md). |
+
+## Manual steps
+
+### Generate oracle JSON only
+
+```bash
+cargo run -p move-lean-difftest
+```
+
+Writes **`difftest/difftest_oracle.json`** (all suites) unless you pass **`--suite`** / **`-o`**. With **`--quiet`**, no JSON on stdout (file only).
+
+### Run Lean checker only
+
+```bash
+cd aptos-move/framework/formal/lean
+lake build difftest
+lake exe difftest ../difftest/difftest_oracle.json
+```
+
+Pass whichever oracle file you generated.
+
+### Exit code (Lean)
+
+**0** if every executed case passes (skipped cases do not fail the run), **1** on failure or bad JSON.
+
+## Layout
+

+2. Add a `DiffTestSuite` in `src/suites/`, register it in `mod.rs` (`all_suites` + **`suites_filtered` match** — must stay in sync; see comment in `mod.rs`).
+3. Run `cargo run -p move-lean-difftest -- --list-suites` to verify the new id appears.
+4. Extend **`funcNameToMapping`** in `AptosFormal.DiffTest.Runner`, and wire Lean **`ModuleEnv`** / natives as needed.

+# Lean column policy: bytecode, natives, and globals (difftest §3)
+
+This document is the **single place** that explains how the **Lean** side of
+`move-lean-difftest` stays aligned with the **VM oracle** for confidential assets
+and other suites. It implements the engineering constraints from
+[`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md) §3
+(*“Lean must be able to run what you test”*).
+
+## 1. Three obligations for every oracle case
+
+For a JSON case to run under `lake exe difftest`, **all** of the following must hold:
+
+1. **Bytecode (or an explicit substitute)**  
+   Either the case maps to **`FuncBody.bytecode`** in `AptosFormal.Move.Programs.*`
+   (hand-written or transcribed from `movement move disassemble`), **or** the team
+   documents a deliberate **native-only** entry (see §2).
+
+2. **`MoveInstr` + `step`**  
+   Every instruction used by that bytecode must be implemented in
+   `AptosFormal/Move/Instr.lean` and `Step.lean`. Missing opcodes → **`.error`** or
+   wrong semantics → oracle mismatch.
+
+3. **Natives**  
+   Every `Call` to a **`FuncBody.native`** must have a Lean implementation that
+   matches the VM on the oracle inputs (usually by delegating to `AptosFormal.Std.*`
+   / `AptosFormal.AptosStd.*` specs, or by a **stub** table documented here).
+
+**Globals:** resource-like behavior is modeled separately (§4); it is **not**
+automatically the same as Aptos `borrow_global` / `move_to` opcodes from the
+binary format.
+
+## 2. Confidential suites: native stubs vs bytecode
+
+| Suite | Lean `ModuleEnv` | Policy |
+|-------|------------------|--------|
+| `confidential_balance`, `confidential_proof` (smoke), `confidential_asset` (layer), `global_resource_smoke` | `confidentialModuleEnv` (`Programs/Confidential.lean`) | **Prefer `FuncBody.bytecode` in `eval`** for oracle rows where the observable result is fixed by simple Move-shaped logic: constant `u64`/`bool`, empty `vector` (`vec_pack`+`ret`), `ld_const`+`ret` for fixed byte vectors (BP DST + SHA3-512 digest + FS golden `msg` + 255×`0u8` short-length `Option`), `vec_pack`+`vec_len`+`neq` for empty-bytes wrong-length `Option`, **`globalMoveTo`/`mutBorrowGlobal`/`readRef`** for `test_read_std_counter` (synthetic key; same `u64` as VM). **Merged CA e2e** (`confidential_asset_e2e::…`): Lean uses indices **40–42** (`bool` witness, void `ret`, fixed abort `65542`) — JSON outcome alignment, not entrypoint replay. **`test_registration_helpers_roundtrip` (35)** and **`test_registration_proof_framework_deterministic_verify_roundtrip` (171):** Lean runs **`Operational.execVerifyRegistrationProof`** on VM-matched wire bytes (`Programs/RegistrationDifftestOracle.lean`) with a **finite table `CryptoOracleWithBoolEq`** (not a general Ristretto interpreter). **171** exercises **`confidential_proof::{prove_registration_deterministic_for_difftest, verify_registration_proof_for_difftest}`** on the same fixture as **35**; Lean column is the **same native** as **35**. Regenerate bytes with `cargo run -p move-lean-difftest --bin print-difftest-registration-wire` if the Move-only path changes. VM still runs full framework code where the harness calls into `aptos_experimental::confidential_balance` / `confidential_proof`. Formal hex corpora under **`corpora/confidential_assets/`** (registration FS `msg`, tagged SHA3-512 digest, Bulletproofs `DST` + digest, **`deserialize_sigma_*.hex`** layout wires, **`serialize_auditor_*.hex`** serializer VM wires) are checked by **`cargo run -p move-lean-difftest -- verify-corpora`** (Rust; same checks as the legacy Python script). |
+| `vector` (`difftest_vector`) | `realModuleEnv` indices **30–33** (`Programs.lean` + `Native.lean`) | `vector::remove`, `swap_remove`, `append`, `singleton` on **`vector`** via **natives** that match the harness oracle (VM↔Lean **no longer skipped** for those rows). |
+| `confidential_elgamal` | Same | Mix of **stub constants** and paths that mirror public APIs; see [`inventory/confidential_assets.md`](inventory/confidential_assets.md) for skips. |
+| Future: CA with real bytecode | TBD | Transcribe bytecode + extend `MoveInstr` / `step` + replace stubs per function as coverage expands. |
+
+Skipped functions and rationale stay in **`difftest/inventory/confidential_assets.md`**
+(and per-package tables under `difftest/inventory/`).
+
+## 3. `confidential_asset` and global storage (Option B vs future work)
+
+The differential plan’s **Option B** remains the default for the **`confidential_asset`**
+suite: only entrypoints that **do not require** a modeled global store appear in
+the VM↔Lean oracle.
+
+Separately, the Lean model now includes **`MachineState`** with **`GlobalResourceKey`**
+(see `Move/README.md`) so **new** bytecode can use abstract **`globalExists`** /
+**`globalMoveTo`** / **`mutBorrowGlobal`** without inventing a one-off native per
+resource. **That is not yet** full Aptos wiring:
+
+- No automatic **`StructTag`** / **`address`** encoding from the Move constant pool.
+- No **`signer`**-checked publish path (values carry `MoveValue.signer`, but the
+  step rules do not enforce `move_to` signer rules).
+- No **fungible asset** / **`object::Object`** store layout.
+
+When a CA path needs those, either extend the key type + stepping rules, add
+targeted natives, or adopt **Option C** (VM-only column) for that slice — and
+update this file + the inventory row.
+
+**Phase L5 (FA / primary store — stub implemented):** `MachineState` now has
+`faBalances : List ((UInt64 × UInt64) × UInt64)` (opaque `(metadataId, ownerKey) ↦ amount`).
+`Step.lean` threads full `MachineState` through `withCG` on every transition.
+New opcodes: **`faReadBalance`** (stack: `owner :: metaId :: rest` → push `u64` balance)
+and **`faWriteBalance`** (`amt :: owner :: metaId :: rest` → update map). `eval` takes an
+optional initial `MachineState` (default `empty`); `Runner.lean` seeds balances for
+`test_fa_stub_balance_answer` to match the Rust `fa_stub` suite constant. A second harness row
+**`test_fa_stub_write_then_read_balance`** checks **`faWriteBalance`** then **`faReadBalance`** on
+**`MachineState.empty`** (Lean index **169**); the VM returns the same pinned **`u64`** constant.
+**`test_registration_fs_message_framework_matches_helpers_golden`** (Lean index **170**) VM-compares
+**`confidential_proof::registration_fs_message_for_test`** against **`difftest_registration_helpers::registration_fs_message_golden_move`**
+(Lean **`ldTrue`** stub).
+**`test_registration_proof_framework_deterministic_verify_roundtrip`** (Lean index **171**) VM-runs production
+**`prove_registration_deterministic_for_difftest`** + **`verify_registration_proof_for_difftest`** on the **35** fixture;
+Lean **`caRegistrationHelpersRoundtripNative`** (same as **35**).
+**`test_registration_fs_message_framework_second_scenario_matches_helpers_golden`** (Lean index **173**) is the
+**`goldenRegistrationInputs2`** counterpart to **170** (`ldTrue` stub).
+**`test_registration_tagged_hash_golden_move_{first,second}`** (Lean **174** / **175**) return the **64**-byte
+**`tagged_hash`** vectors for FS golden **1** / **2** (`ldConst` **47** / **48** + `ret`, matching **`verify-corpora`** hex).
+This is **not**
+Aptos `primary_fungible_store` / `Object` semantics — transactional CA e2e rows remain
+**witness Lean** until a richer model lands.
+
+## 4. `GlobalResourceKey` (Lean L4 scaffolding)
+
+Defined in `lean/AptosFormal/Move/Value.lean`:
+
+- `address : ByteArray` — publish site.
+- `structTagHash : Nat` — stand-in fingerprint; may coexist with optional `structTag`.
+- `instanceNonce : Nat` — reserved for FA / object disambiguation (often `0`).
+- `structTag : Option StructTag` — optional `(account, module, struct)` **byte** path
+  (no generic args); not tied to the VM constant pool.
+
+`MachineState.globals : List (GlobalResourceKey × RefId)` maps keys to heap cells
+in the shared `ContainerStore`. `globalMoveToSigned` + `ldSigner` model a minimal
+signer-address check vs `move_to` (see `Step.lean`). Smoke bytecode:
+`Programs/GlobalSmoke.lean`, tests: `Tests/GlobalSmoke.lean`.
+
+## 5. When to bump `schema_version`
+
+If the JSON oracle shape or comparison rules change, bump **`CURRENT_SCHEMA_VERSION`**
+in Rust and document in [`ORACLE_CHANGELOG.md`](ORACLE_CHANGELOG.md). Changes to
+**Lean-only** stubs without oracle field changes do not require a schema bump.

+# Independent / gold vectors — Confidential assets (scaffold)
+
+This directory supports **`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md` §4.3 (iii)** and the **§4.5** checklist row **“independent / gold crypto vectors”**: evidence that alignment is not only **VM ↔ same-repo Lean**, but also consistent with **audited third-party or test-vector expectations** where applicable.
+
+## Intended use
+
+- **Small, versioned blobs** (hex or JSON) with a one-line **provenance** (e.g. RFC test vector id, internal golden name, Move `#[test]` source path).
+- Consumed by future harness or **offline checks** (e.g. hash-to-curve expected encoding, scalar ops, transcript bytes already mirrored in `AptosFormal.Experimental.ConfidentialAsset.Registration.*` goldens).
+- **Not** a substitute for formal proofs; complements **[`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](../../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)** Workstream A.

+# Difftest inventory — Confidential assets (experimental)
+
+**Independent / gold vectors (§4.3 iii):** scaffold [`../corpora/confidential_assets/README.md`](../corpora/confidential_assets/README.md) — populate to strengthen peer-reviewable evidence beyond VM↔same-repo Lean.
+
+**Native / crypto map (FV Workstream A):** [`confidential_native_matrix.md`](confidential_native_matrix.md).
+
+**Move sources:** `aptos-move/framework/aptos-experimental/sources/confidential_asset/`  
+**Modules:** `confidential_asset`, `confidential_proof`, `confidential_balance`, `ristretto255_twisted_elgamal` (+ `confidential_gas_e2e_helpers` for tests)  
+**Rust suite ids (registered):** `global_resource_smoke`, `confidential_balance`, `confidential_elgamal`, `confidential_proof`, `confidential_asset`, **`fa_stub`** (FA `MachineState` stub alignment), meta **`confidential`** (the four CA-related suites + `fa_stub`; `global_resource_smoke` is separate).  
+**Lean:** `AptosFormal.Move.Programs.Confidential` + `DiffTest.Runner` mappings for the oracle function names listed in those suites.
+
+## 1. Testing discipline (confidential assets are not assumed correct)
+
+- **Oracle** = output of the **Move VM** on pinned bytecode + inputs. If CA Move has a bug, the oracle records **that** behavior.
+- **Lean** is a **second implementation** of the same *intended* semantics (`Move.step` + natives). When both are wired, **disagreement fails CI** — you then determine whether Move, Lean transcription, or Lean natives are wrong.
+- **Regression workflow:** after a **deliberate** Move fix, **regenerate** oracles; if Lean was matching old buggy behavior, tests fail until Lean is fixed — that is **desirable**.
+
+Do **not** hand-edit oracle JSON to “match Lean” without a VM run.
+
+## 2. Transitive natives / external modules (closure for proof + crypto paths)
+
+The CA `.move` files under `confidential_asset/` declare **no** `native fun` themselves; execution relies on:
+
+| Dependency | Used for (typical) |
+| ---------- | ------------------ |
+| `aptos_std::ristretto255` | Points, scalars, mul/add/sub, decompress, … |
+| `aptos_std::aptos_hash` | Tagged SHA3-512 (Fiat–Shamir challenges, etc.) |
+| `aptos_std::ristretto255_bulletproofs` | Range proof verify / prove paths |
+| `std::vector`, `std::option`, `std::bcs` (if any) | Structure per compiler |
+| `aptos_framework::*` / FA / object | **Entrypoints** in `confidential_asset` (deposits, transfers, …) |
+
+**Lean implication:** every native on a **VM↔Lean** path needs a Lean binding or a documented **VM-only** cut.
+
+## 3. `confidential_asset` — entrypoints & key `public fun`
+
+| Symbol | Kind | Observable | Planned mode | Notes |
+| ------ | ---- | ----------- | ------------ | ----- |

+| `serialize_auditor_eks` / `serialize_auditor_amounts` | `public fun` | `vector` | VM↔Lean: `0x1::difftest_confidential_asset_layer` calls the real helpers (empty + non-empty EKs **32 / 64 / 96 / 128 / 160 / 192** B; pending/actual wires including **512**/**768** B permutations; corpora under [`corpora/confidential_assets/`](../corpora/confidential_assets/)). |

+| `prove_*` / `serialize_*` / `deserialize_*` | `public` | various | VM-only or VM↔Lean | Case-by-case; `prove_*` may be `test_only` — confirm in source |
+| `get_fiat_shamir_*` / `get_bulletproofs_*` | `public` | constants | VM↔Lean candidate | Trivial oracle rows |
+
+## 5. `confidential_balance`
+
+| Symbol | Kind | Observable | Planned mode | Notes |
+| ------ | ---- | ----------- | ------------ | ----- |
+| `new_*_no_randomness`, `new_*_from_bytes`, `compress_balance`, `decompress_balance`, `balance_to_bytes` | `public` | values / `Option` | VM↔Lean candidate | Good **Phase 2** targets (crypto + structure) |

+| `balance_equals` / `balance_c_equals` / `is_zero_balance` | `public` | `bool` | VM↔Lean candidate | |
+| `split_into_chunks_u64` / `split_into_chunks_u128` | `public` | `vector` internally | VM↔Lean | Harness tests (`test_split_into_chunks_*_first_chunk`) return **`bool`** (scalar check inside Move); oracle carries **no** `vector` — no JSON schema extension required for these rows. |

+| `generate_balance_randomness` / `new_*_from_u128` / `verify_*` | `test_only` / `public` | | VM-only | Mark test-only paths in harness |
+
+## 6. `ristretto255_twisted_elgamal`
+
+| Area | Observable | Planned mode | Notes |
+| ---- | ----------- | ------------ | ----- |
+| Ciphertext / pubkey **constructors**, `ciphertext_add*`, `compress*`, `decompress*`, `ciphertext_equals`, … | points / bool / bytes | VM↔Lean candidate | Foundation for balance proofs |

+## 9. VM-only vs VM↔Lean (decision log)
+
+| Situation | Choice |
+| --------- | ------ |
+| Lean `MoveInstr` / `Step` / native missing | **VM-only** oracle + **Blocked** row until Lean catches up **or** narrow case. |
+| Pure `u64` / `vector` / bool return, no globals | **VM↔Lean** once `ModuleEnv` + runner wired. |
+| Entry touching `borrow_global` / FA | **Blocked** for full `Move.*` until L4-style store (see formal verification plan) **or** test `*_internal` with synthetic locals only. |
+
+## 10. Changelog
+
+| Date | Change |
+| ---- | ------ |
+| 2026-04-10 | Phase 0 inventory created; suite `confidential` not registered yet. |
+| 2026-04-10 | Phases 1–2 + partial 3–4: suites `confidential_balance`, `confidential_proof`, `confidential_asset` + meta `confidential`; Lean `Programs/Confidential.lean`; **Phase 4 = Option B** (globals-free slice only). |
+| 2026-04-12 | Documented **stretch** rows (store/FA entrypoints, full `verify_*` + registration bytecode, Lean bytecode parity) with pointers to plan **§7**; noted **§7.0** `e2e-move-tests` already covers transactional VM + real verifiers. |
+| 2026-04-12 | `serialize_auditor_*` promoted to non-`#[test_only]` `public fun` on `confidential_asset`; difftest calls them from `0x1::difftest_confidential_asset_layer` (VM↔Lean unchanged on empty vectors). |
+| 2026-04-12 | More `confidential_balance` VM rows (`balance_equals` / `balance_c_equals` / `sub_balances_mut` smoke); `get_fiat_shamir_registration_sigma_dst` `#[view]` on `confidential_proof`; Lean `Programs/Confidential` indices 47–51 (balance bool stubs + registration DST const). |
+| 2026-04-12 | Lean **Phase L5 stub:** `MachineState.faBalances`, `faReadBalance` / `faWriteBalance`, `eval … initMs`, `fa_stub` Rust suite + confidential index 52 + Runner seed for `test_fa_stub_balance_answer`. |
+| 2026-04-12 | Near-term CA difftest: Runner aliases for legacy `serialize_auditor_*_empty_mirror` names; `split_into_chunks_*` inventory clarified (**bool** harness, no `vector` in JSON); ElGamal **`ciphertext_add_assign`** VM row + Lean stub index **53**. |

+# CA native & crypto dependency matrix (living)
+
+**Purpose:** Track what the **Move VM** executes on confidential-asset paths vs what **`AptosFormal.Move` / difftest** model today. Feeds **[`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](../../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)** Workstream **A** (native specs) and **[`STUB_POLICY.md`](../STUB_POLICY.md)**.
+
+**Legend**
+
+| Status | Meaning |
+|--------|---------|
+| **Oracle** | VM↔Lean agree on harness / merged JSON rows (may be constant witness, not full native). |
+| **Lean spec** | Pure Lean (`AptosFormal.AptosStd.*`, `Std.*`) used in proofs or `native_decide` checks. |
+| **Open** | No Lean executable spec on CA paths; difftest witness or VM-only. |
+
+---
+
+## 1. `aptos_std::aptos_hash`
+
+| Surface | Move | Lean / difftest | Status |
+|---------|------|-----------------|--------|
+| SHA3-512 | `sha3_512_internal` → `sha3_512` | `AptosFormal.AptosStd.Hash.Sha3_512` | **Lean spec** + **Oracle** (BP DST digest, tagged registration hash, …) |
+
+---
+
+## 2. `aptos_std::ristretto255` (internal natives; public wrappers)
+
+Move: `aptos-move/framework/aptos-stdlib/sources/cryptography/ristretto255.move` — **point / scalar** handles with `*_internal` natives (decompress, mul, add, `multi_scalar_mul`, `scalar_uniform_from_64_bytes`, …).
+
+| Used heavily from | Notes | Lean / difftest |
+|--------------------|-------|-----------------|
+| `confidential_proof` | Registration Schnorr, sigma layouts, BP driver | **Oracle** + **L0** transcript (`TranscriptAlignment`); **corpora** `deserialize_sigma_*.hex` (+ **`verify-corpora`**) for VM layout-`Some` sigma wires; full curve **`Open`** in `eval` for entrypoints. |
+| `confidential_balance` | Compress/decompress balances | **Oracle** (`confidential_balance` suite); partial **Lean spec** on narrow rows. |
+| `ristretto255_twisted_elgamal` | ElGamal ops (no own natives) | **`confidential_elgamal`** suite. |
+
+---
+
+## 3. `aptos_std::ristretto255_bulletproofs`
+
+Move: `ristretto255_bulletproofs.move` — `verify_range_proof_internal`, `verify_batch_range_proof_internal`, `prove_range_internal`, …
+
+| Surface | Lean / difftest | Status |
+|---------|-----------------|--------|
+| Range proof verify / prove | DST string + SHA3-512 digest in oracle; **not** full BP verify in Lean `eval` | **Oracle** + **Open** for bit-for-bit BP in Lean |

+
+**Lean length facts:** `AptosFormal.Move.Programs.Confidential.bulletproofsDstBytes_length` / `bulletproofsDstSha3Bytes_length`.
+
+---
+
+## 4. `aptos_experimental::confidential_*` (application Move)
+
+| Module | Declares `native fun`? | Notes |
+|--------|-------------------------|--------|
+| `confidential_asset` | **No** | FA + framework calls; e2e VM depth + merged JSON **witness** rows in Lean. |
+| `confidential_proof` | **No** | Calls stdlib crypto natives. |
+| `confidential_balance` | **No** | Calls stdlib crypto / structure. |
+| `ristretto255_twisted_elgamal` | **No** | Wrapper over `ristretto255`. |

+## 7. Next actions (suggested)
+
+1. Expand this table **per public `fun`** on hot paths (owner + target L-level from FV plan).
+2. For each **`ristretto255::*`** used from `confidential_proof::verify_*`, map to **Lean spec or axiom** row (Workstream A exit: “native → status” table).
+3. Decide **BP strategy**: oracle-only vs bounded lemma vs external reference harness.

+**Rust suite id (when implemented):** ``  
+**Lean module / `ModuleEnv`:** ``
+
+## Methodology
+
+- **VM↔Lean:** Oracle bytes come from **VM execution**; Lean must **independently** reproduce them. A **mismatch** means Move bytecode, Lean transcription, Lean `Step`, or Lean natives disagree — **investigate**; do not “fix” the test to match Lean without VM evidence.
+- **VM-only:** Oracle for regression / tooling; Lean skipped until wired.
+- **Blocked:** Document blocker (e.g. globals, missing `MoveInstr`).
+
+## Native / dependency closure
+
+*(List `use` lines and any `native fun` in transitive modules the VM will execute for your cases.)*

+  cargo run -p move-lean-difftest -- verify-corpora   (hex corpus checks for corpora/confidential_assets/)

+  --suite ID   Run only one suite (repeatable). Known IDs: {ids}. Omit = all suites.
+  --list-suites   Print known suite IDs and exit (for scripts and inventory docs).
+  -o, --output PATH   Write JSON here (relative to this crate dir, or absolute).
+  --quiet    Do not print progress to stderr or JSON to stdout (file is still written)
+  -h, --help This help
+
+Default output path (when --output omitted):
+  - all suites: {DEFAULT_ORACLE_ALL}
+  - --suite bcs: difftest_oracle_bcs.json
+  - --suite bcs --suite hash: difftest_oracle_bcs_hash.json (ids sorted)
+
+The JSON is the VM ground truth for `lake exe difftest ` — Lean checks against it; neither side assumes the other is correct.
+
+See `merge --help` for combining oracle JSON files; appended `skip_lean` flags are preserved unless you pass `--force-skip-lean`.

+# Differential test runner
+
+Reads JSON test vectors produced by the Rust `move-lean-difftest` harness,
+runs each test case through the Lean Move evaluator, and compares results.
+
+Full workflow: `./aptos-move/framework/formal/difftest.sh` from the repo root, or see
+`aptos-move/framework/formal/difftest/README.md`. The default VM oracle is `difftest/difftest_oracle.json`.
+
+Usage: `lake exe difftest `
+
+This is a runtime comparison (not a proof). It reports pass/fail for each
+test case, providing empirical evidence of model fidelity between our Lean
+evaluator and the real Move VM.

+# Eval smoke tests for the **real** `verify_registration_proof` bytecode
+
+Runs `eval` on the 83-instruction bytecode transcribed from the `movement` v7.4
+compiler output, using a concrete `RegistrationNativeOracle` with symbolic
+integer-tagged `MoveValue.u64` values for points/scalars.
+
+Because the real bytecode passes `ek` as `&CompressedPubkey` (an immutable
+reference), the initial `MachineState` must have the ek value pre-allocated
+in the `ContainerStore` and the arg list must contain `.immRef ekRefId`.
+
+Tests:
+1. **Valid proof**: `eval` returns `ExecResult.returned []` (success, void return)
+2. **Invalid proof**: `eval` returns `ExecResult.aborted 65537`

+# Bytecode eval ≡ functional simulation (L2 ≡ L1.5)
+
+Proof that the bytecode evaluator `eval` on the transcribed 83-instruction
+`verify_registration_proof` (reference-semantic, from `movement` v7.4
+compiler output) agrees with the functional simulation
+`verifyRegistrationBytecodeResult` for any oracle — up to MachineState
+(the container store is non-empty after execution but irrelevant to the
+return values / abort code).
+
+## MachineState note
+
+The real bytecode uses `immBorrowLoc` / `mutBorrowLoc` / `nativeRef`
+calls, so `eval` returns `.returned [] ms` where `ms` has a populated
+`ContainerStore`. The functional sim returns `.returned [] MachineState.empty`.
+We compare via `ExecResult.dropMs` which projects away the `MachineState`.
+
+## Proof architecture
+
+The proof uses `@[simp]` lemmas to normalize both sides to the same
+match tree:
+
+**Eval side:**
+1. `run_succ_runStep` rewrites `run env frame cs stack ms (n+1)` →
+   `runStep env (step env frame cs stack ms) n`
+2. `step` unfolds to `handleNativeResult (impl args) numReturns ...`
+   (or `nativeRef` dispatch for ref-aware functions)
+3. `runStep_handleNativeResult_ret1` collapses to
+   `match oracleResult with | some [v] => run env ... | _ => .error`
+
+**Func side:**
+4. `match_single?` rewrites `match (single? x) with | some v => f v | _ => g`
+   to `match x with | some [v] => f v | _ => g`
+5. `bind_single?` rewrites `single? x >>= f` to
+   `match x with | some [v] => f v | _ => none`
+
+**Bridging:**
+6. `match_match_some_single_none` fuses
+   `match (match x with | some [v] => f v | _ => none) with | some w => g w | none => h`
+   into `match x with | some [v] => match f v with | some w => g w | none => h | _ => h`
+   (needed for `buildFSMessageMv`'s `Option MoveValue` boundary in `blockCDE`)
+
+After normalization, `simp`'s congruence closes matching branches.
+Remaining abstract branch splits are handled by `split <;> simp`.
+-/
+
+/-! ## MachineState projection
+
+The real bytecode populates the `ContainerStore` via `immBorrowLoc` /
+`mutBorrowLoc` / `nativeRef` calls, so `eval` returns a non-empty
+`MachineState`. The functional sim returns `MachineState.empty`.
+`dropMs` projects away the `MachineState` to enable comparison.

+# Functional simulation of `verify_registration_proof` bytecode
+
+`verifyRegistrationBytecodeResult` computes the same result as `eval` on the
+67-instruction transcribed bytecode, but expressed as a readable Lean function
+on `MoveValue`s. It serves as the intermediary layer in the refinement chain:
+
+```
+L2  eval (67 instrs)  ≡  L1.5  verifyRegistrationBytecodeResult  ≡  L1  execVerifyRegistrationProof
+```
+
+## Design rationale
+
+Proving `eval ≡ func` requires stepping through 67 bytecode instructions
+symbolically. Proving `func ≡ exec` is a straightforward functional equivalence
+under oracle coherence. By splitting the proof at this boundary:
+
+- The **`eval ≡ func`** proof is mechanical (checked by `native_decide`
+  on concrete oracles, or by block-simulation lemmas abstractly)
+- The **`func ≡ exec`** proof is algebraic (matching function shapes)
+
+An auditor can verify `func` by visual inspection against the bytecode source.
+
+**Import discipline:** This file uses only light imports (no Mathlib/ZMod) so
+that `native_decide` can elaborate `func` efficiently.

-Refinement notes: Lean `Prop` vs this repo’s Move `verify_registration_proof`
-(`aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move`).
+# Refinement: bytecode `eval` ↔ `verifyRegistrationProofProp`
+
+Connects the **bytecode-level** execution of the transcribed
+`verify_registration_proof` (via `eval` in `Step.lean`) to the existing
+**spec-level** propositions:
+
+- `verifyRegistrationProofProp` (`VerifyMath.lean`) — mathematical spec (L0)
+- `execVerifyRegistrationProof` (`Operational.lean`) — `Option Unit` runner (L1)
+- `verifyRegistrationBytecodeResult` (`FunctionalSim.lean`) — functional simulation (L1.5)
+
+The four-layer refinement chain is:
+
+```
+L2  eval (bytecode)
+  ≡  L1.5  verifyRegistrationBytecodeResult (functional simulation)
+    ≡  L1  execVerifyRegistrationProof (Option Unit)
+      ↔  L0  verifyRegistrationProofProp (Prop)
+```
+
+**L2 ≡ L1.5** (`eval_eq_func`): up to `MachineState` (via `.dropMs`), since the real
+83-instruction bytecode populates the `ContainerStore` via references.
+Abstract proof (`eval_eq_func_100`) requires symbolic bytecode stepping (sorry).
+Concrete instances verified by `native_decide` in `BytecodeDifftestEval.lean`.
+
+**L1.5 ≡ L1** (`func_success_implies_exec_some`, `func_abort_implies_exec_none`):
+algebraic equivalence under oracle coherence. Both directions proven.
+
+**L1 ↔ L0** (`execVerifyRegistrationProof_iff`): already proven in `Operational.lean`.
 
 See `REGISTRATION_VERIFY_REVIEW.md` (under `aptos-move/framework/formal/`) for obligations §6.

+/-! ## L2 ≡ L1.5: eval ≡ verifyRegistrationBytecodeResult (up to MachineState)
+
+The real 83-instruction bytecode uses `immBorrowLoc` / `mutBorrowLoc` /
+`nativeRef` calls, so `eval` returns a populated `ContainerStore` in
+its `MachineState`. The functional sim returns `MachineState.empty`.
+We compare via `.dropMs` which projects away the `MachineState`.
+
+**Fuel lifting:** `eval_fuel_ge` shows that non-error results are
+fuel-monotone. Combined with `eval_eq_func_100` (at fuel 200) and
+`func_trichotomy`, we lift to arbitrary `fuel ≥ 200`.
+
+The `.error` case (oracle returns garbage) requires an error-fuel-monotonicity
+argument that the computation terminates in < 200 steps. This sorry is
+**vacuous for callers** which assume `.returned` or `.aborted`. -/

+# L4: `register` entry-point specification stub
+
+The Move `register` entry function (`confidential_asset.move`, lines 249–272):
+
+```move
+public entry fun register(
+    sender: &signer,
+    token: Object,
+    ek: vector,
+    registration_proof_commitment: vector,
+    registration_proof_response: vector
+) acquires FAController, FAConfig {
+    let ek = twisted_elgamal::new_pubkey_from_bytes(ek).extract();
+    let cid = (chain_id::get() as u8);
+    let user = signer::address_of(sender);
+    confidential_proof::verify_registration_proof(
+        cid, user, @aptos_experimental, &ek, object::object_address(&token),
+        registration_proof_commitment, registration_proof_response
+    );
+    register_internal(sender, token, ek);
+}
+```
+
+## What this file captures
+
+1. **Entry-point decomposition**: `register` = parse ek + verify proof + global move_to
+2. **Verify-then-store property**: if `register` returns normally, the proof was accepted
+3. **Global state mutation**: `register_internal` creates a `ConfidentialAssetStore` resource
+
+## What this file does NOT capture (future work)
+
+- Full bytecode transcription of `register` (needs signer/chain_id/object natives)
+- `register_internal` body (needs `move_to`, `borrow_global`, FAConfig access)
+- Abort conditions (ek parse failure, FAConfig checks, already registered)
+
+## Refinement path
+
+```

+  ↠  L3  registerEntrySpec (this file)

+and **`test_pending_from_short_len_is_none`** via a **255-byte** `u8` constant pool entry (`len ≠ 256`).

+(`chain_id=9`, `@0x1`/`@0x2`/`@0x3`, dk=42, k=9999).
+
+Wire bytes are generated by:
+
+`cargo run -p move-lean-difftest --bin print-difftest-registration-wire`
+
+The carrier `Fin 8` is a **table oracle**: only the `pointMul` / `pointAdd` / `decompress` paths exercised
+by `Operational.execVerifyRegistrationProof` on this trace are populated; everything else maps to a
+sink state. This is **not** a general Ristretto model — it is a sound way to run `execVerifyRegistrationProof`
+in `lake exe difftest` for this one oracle row (see `STUB_POLICY.md`).

+# Vector bytecode programs
+
+Both hand-written and real compiler-output bytecode for `std::vector` functions.
+
+## Hand-written programs
+
+Manually composed bytecode that inlines the logic of `vector::reverse`,
+`vector::contains`, and `vector::index_of`. These were the initial model
+validation targets.
+
+## Real compiler output
+
+Bytecode transcribed directly from `movement move disassemble` on the
+compiled `move-stdlib` package. Each program matches the compiler's output
+instruction-for-instruction, including branch targets, `MoveLoc`/`Pop`
+cleanup patterns, and calling conventions.
+
+**Source:** `movement move compile --package-dir aptos-move/framework/move-stdlib`
+then `movement move disassemble --bytecode-path .../bytecode_modules/vector.mv`

+
+## How the directories compose
+
+**Std.\* and Experimental.\*** define *what* Move functions should compute — pure
+Lean functions mapping inputs to outputs. These are the **specifications**.
+
+**Move.\*** defines *how* Move programs execute — a bytecode interpreter in Lean
+that takes a sequence of instructions and a state, and produces a new state.
+This is the **execution model**.
+
+**Refinement.\*** proves that specific Move bytecode programs, when evaluated under
+the execution model, produce results matching the specifications. These are the
+**correctness proofs**.
+
+Any file in `Move/` can `import AptosFormal.Std.Bcs.Primitives` and use `u64Le`
+directly — they share the same Lake project and import system.
+
+## Implementation plan
+
+### Phase 1: Values and types
+
+Define `MoveValue` — the runtime value type matching Move's bytecode-level values:
+
+```lean
+inductive MoveValue
+  | u8 (n : UInt8)
+  | u16 (n : UInt16)
+  | u32 (n : UInt32)
+  | u64 (n : UInt64)
+  | u128 (n : Nat)
+  | u256 (n : Nat)
+  | bool (b : Bool)
+  | address (bytes : ByteArray)
+  | vector (elemType : MoveType) (elems : List MoveValue)
+  | struct (fields : List MoveValue)
+```
+
+Reference: `third_party/move/move-binary-format/src/file_format.rs` for the
+canonical value representation and `third_party/move/move-vm/types/src/values/`
+for the runtime value types.
+
+### Phase 2: Instruction set
+
+Define `MoveInstr` — a subset of Move bytecode instructions, starting with
+pure operations. **Abstract** global ops (`globalExists` / `globalMoveTo` /
+`globalMoveToSigned` / `mutBorrowGlobal`) model publishing keyed by
+`GlobalResourceKey`; optional `StructTag` bytes live on the key (see `Value.lean`).
+Full Aptos BCS / generic `StructTag`, **`Object`** layout, and VM-accurate
+`BorrowGlobal` from metadata remain future work (see L4 gap below).
+
+- Integer arithmetic: `Add`, `Sub`, `Mul`, `Div`, `Mod`
+- Comparisons: `Lt`, `Gt`, `Le`, `Ge`, `Eq`, `Neq`
+- Logic: `And`, `Or`, `Not`
+- Stack: `LdConst`, `Pop`, `CopyLoc`, `MoveLoc`, `StLoc`
+- Control: `Branch`, `BrTrue`, `BrFalse`, `Ret`
+- Calls: `Call` (with a native function dispatch table)
+- Casting: `CastU8`, `CastU64`, etc.
+- Vector: `VecPack`, `VecLen`, `VecPushBack`, `VecPopBack`, `VecSwap`
+- Abort: `Abort`
+
+Reference: `Bytecode` enum in `third_party/move/move-binary-format/src/file_format.rs`.
+
+### Phase 3: Execution state and evaluator
+
+Define the execution state and a small-step evaluator:
+
+```lean
+structure Frame where
+  code : Array MoveInstr
+  pc : Nat
+  locals : Array (Option MoveValue)
+
+structure ContainerStore where
+  store : Array MoveValue
+
+structure MachineState where
+  containers : ContainerStore
+  globals : List (GlobalResourceKey × RefId)
+  faBalances : List ((UInt64 × UInt64) × UInt64) := []
+
+def step (env : ModuleEnv) (frame : Frame) (callStack : List Frame)
+    (stack : List MoveValue) (ms : MachineState) : ExecResult := ...
+```
+
+`ModuleEnv` bundles the constant pool and function table. Native functions
+are modeled as Lean functions (`List MoveValue → Option (List MoveValue)`),
+allowing crypto operations (SHA3, Ristretto) to be plugged in from `Std.*`
+definitions without modeling Rust internals. `ContainerStore` is the
+pure-functional model of the VM's `Container` sharing mechanism
+(`Rc>>`).
+
+**`MachineState`:** pairs that heap with `globals`, a list mapping
+`GlobalResourceKey` (publish `address` bytes + `structTagHash` + optional
+`instanceNonce` + optional `StructTag` path bytes) to a `RefId` into the same store.
+Additionally **`faBalances`** is a difftest-only stub map `(metadataId, ownerKey) ↦ u64`
+(see `faReadBalance` / `faWriteBalance` in `Instr.lean` and Phase L5 in
+[`../../../difftest/STUB_POLICY.md`](../../../difftest/STUB_POLICY.md)).
+`MachineState.ofContainers` / coercion lifts a locals-only heap (`globals := []`,
+`faBalances := []`).
+Abstract instructions `globalExists`, `globalMoveTo`, `globalMoveToSigned`,
+`mutBorrowGlobal`, and `ldSigner` live in `Instr.lean` (not the real
+`file_format.rs` global opcodes yet). Smoke bytecode: `Programs/GlobalSmoke.lean`;
+kernel-checked equalities: `Tests/GlobalSmoke.lean`.
+
+**L4 gap (remaining):** we still do **not** model full Aptos **`StructTag`** BCS
+(including generic type arguments), real **`Object`** /
+**`primary_fungible_store`** layout, or VM-accurate **`BorrowGlobal`** keyed off
+compiled metadata. `globalMoveToSigned` checks signer address bytes against
+`GlobalResourceKey.address` only (no module publish rules). The `faBalances` stub
+is for **narrow** oracle alignment only; extending keys + `step` + difftest
+inventory rows remains the path for fuller FA. See
+[`../../../difftest/STUB_POLICY.md`](../../../difftest/STUB_POLICY.md).
+
+Reference: `third_party/move/move-vm/runtime/src/interpreter.rs` for the
+execution loop.
+
+### Phase 4: Bytecode representations of specific functions
+
+Translate specific Move functions to their bytecode representation as Lean
+values of type `Array MoveInstr`. Start with simple stdlib functions:
+
+- `bcs::to_bytes`
+- `vector::reverse`
+- `vector::length`
+
+These can be obtained by compiling the Move source and inspecting the bytecode
+output (`movement move disassemble`).
+
+### Phase 5: Refinement proofs — Core (done)
+
+Prove that bytecode programs, evaluated under `step`, produce results matching
+the specs in `Std.*`. These Core proofs are `rfl` — Lean's kernel verifies the full
+evaluation chain by definitional reduction, for all inputs (not just goldens).
+(`vector::contains` is handled separately in `Refinement/Vector.lean`; see Phase 6b / 8.)
+
+Completed theorems in `Refinement/Core.lean`:
+- `addU64_correct` — `a + b` for all `UInt64`
+- `isZeroU64_correct` — `n == 0` for all `UInt64`
+- `bcsU64_correct` — bytecode wrapper matches `Std.Bcs.u64Le` spec for all `UInt64`
+- `readViaRef_correct` — immutable borrow + read round-trips for all `UInt64`
+- `incViaRef_correct` — mutable borrow → read → add → write → read for all `UInt64`
+- `vecPushAndLen_correct` — reference-based vector push + length for all vectors
+
+### Phase 6: Expand move-stdlib coverage
+
+Add references to the instruction set and execution model, then prove
+correctness of fundamental stdlib functions:
+
+**6a. Add references to the model (done):**
+- `MoveInstr`: `readRef`, `writeRef`, `freezeRef`, `immBorrowLoc`, `mutBorrowLoc`,
+  `immBorrowField`, `mutBorrowField`, plus reference-level vector ops
+  (`vecLenRef`, `vecPushBackRef`, `vecPopBackRef`, `vecSwapRef`, etc.)
+- `MoveValue`: `mutRef`/`immRef` constructors carrying a `RefId` index
+- `ContainerStore`: pure-functional model of the VM's `Container` sharing
+  (`Rc>>`), threaded through `step`/`run`/`eval`
+- Proved three reference programs correct via `rfl`: `readViaRef_correct`,
+  `incViaRef_correct`, `vecPushAndLen_correct`
+
+**6b. Stdlib vector operations:**
+- `vector::reverse` — loop with `swap` via `VecSwapRef` (bytecode + smoke tests;
+  universal refinement proof still open).
+- `vector::contains` — loop with `VecImmBorrow` + `ReadRef` + `Eq`. Specs in
+  `Std/Vector/Operations.lean`. Smoke tests: `Tests/Vector.lean` (`native_decide`).
+  **Refinement:** `Refinement/Vector.lean` proves `vectorContains_returnValues` for
+  the hand-written `vectorContainsCode` in `Programs/Vector.lean`, against
+  `Std.Vector.contains`, with `xs.length < UInt64.size` so indices match `u64`
+  comparisons (see theorem statement). Differential tests cover `vector::contains`
+  in [`../../../difftest/README.md`](../../../difftest/README.md).
+- `vector::index_of` — loop returning `(bool, u64)` (bytecode + smoke tests;
+  universal refinement proof still open).
+
+**6c–6e.** Remaining stdlib coverage (option, math, BCS) — same approach.
+
+### Phase 7: Model fidelity testing
+
+The Lean evaluator (`Move.Step`) is a hand-written translation of the Rust
+VM (`interpreter.rs`, `values_impl.rs`). Before proving universal theorems
+about it, we need confidence that the translation is correct.
+
+**7a. Use real compiled bytecode (done):**
+
+Compiled `move-stdlib` with `movement move compile` and disassembled
+`vector.mv` to extract the real bytecode for `contains`, `index_of`,
+`reverse`, and `reverse_slice`. Transcribed these instruction-for-instruction
+into `Programs.lean` as `realContainsCode`, `realIndexOfCode`,
+`realReverseCode`, and `realReverseSliceCode`.
+
+This immediately exposed two model fidelity bugs:
+
+1. **`Eq`/`Neq` on references:** The real VM dereferences both sides before
+   comparing (`ContainerRef::equals`, `IndexedRef::equals` in `values_impl.rs`).
+   Our model was comparing `RefId` values, so two references to equal values
+   at different container slots would compare as unequal. Fixed in `Step.lean`.
+
+2. **Double-advance in `Ret`:** `Call` saves the caller frame at `pc + 1`,
+   but `Ret` applied `advance` again, skipping the instruction after the call.
+   This meant any program using inter-function calls (which all real compiler
+   output does — `reverse` calls `reverse_slice`) would crash. Fixed by
+   removing the redundant `advance` from `Ret`'s return-to-caller case.
+
+Also documented: real bytecode uses *only* reference-level vector operations
+(`VecLen`, `VecImmBorrow`, `VecSwap`, etc.) — never the value-level variants.
+The compiler's `MoveLoc` + `Pop` cleanup pattern before `Ret` is faithfully
+modeled. All 16 smoke tests pass (5 `contains`, 3 `index_of`, 5 `reverse`,
+plus the existing hand-written tests).
+
+**7b. Differential testing against the real VM:**
+- Run shared test vectors through both the Rust Move VM and the Lean evaluator
+- Compare outputs (return values, abort codes, error conditions)
+- This validates that `step` faithfully models `execute_code_impl`
+- Implemented: Rust `move-lean-difftest` + Lean `difftest` exe. **Run:** `./aptos-move/framework/formal/difftest.sh` from repo root, or see [`../../../difftest/README.md`](../../../difftest/README.md).
+
+**7c. Expand test coverage:**
+- Randomized inputs (property-based testing) for broader coverage
+- Edge cases: empty vectors, max-length vectors, overflow, abort paths
+
+Differential testing (7b) plus smoke tests give empirical confidence that the
+model tracks the real VM; refinement proofs on top then connect that model to
+stdlib-style specs in Lean.
+
+### Phase 8: Inductive refinement proofs (partially done)
+
+Universally quantified correctness for stdlib-style bytecode, using induction
+and loop invariants where needed:
+
+- **`vector::contains` (done for the formalized hand-written bytecode):**
+  `Refinement/Vector.lean` — `vectorContains_returnValues` / `vectorContains_correct`
+  (hypothesis `xs.length < UInt64.size`, adequate fuel). Proof is kernel-checked
+  (no `sorry`). The proof targets the curated bytecode wired as stdlib function
+  index 18 in `stdModuleEnv`, not a compiler-equality claim for every toolchain
+  output.
+- **`vector::reverse`:** universal refinement vs `List.reverse` — open.
+- **`vector::index_of`:** universal refinement vs the spec in
+  `Std/Vector/Operations.lean` — open.
+
+These `∀`-theorems are checked by Lean's kernel for all inputs satisfying the
+stated hypotheses, unlike difftest goldens alone.
+
+### Phase 9: Composite stdlib and framework functions
+
+Once the stdlib foundation is solid, prove correctness of higher-level
+functions that compose multiple primitives:
+
+- `string` operations (UTF-8 encoding, `string::append`, `string::length`)
+- `simple_map` / `smart_table` lookups and insertions
+- `coin::transfer`, `coin::merge`, `coin::extract`
+- `account::create_account`, `account::exists_at`
+
+These exercise the full model — references, structs, **abstract** global
+publishing (`MachineState` / `GlobalResourceKey`; not yet FA-accurate), native
+calls, and control flow — on the functions developers interact with most.
+

+# Vector operation specifications
+
+Pure Lean specifications of Move's `vector` module functions.
+Each definition here states *what* a vector operation should compute,
+independent of how the bytecode implements it.
+
+These specs serve as the target for refinement proofs: we prove that
+evaluating the bytecode program under `Move.Step` produces results
+matching these definitions for all inputs.

+**One command** (from repo root): `./aptos-move/framework/formal/difftest.sh` — runs the Rust oracle (all suites), then Lean, using **`difftest/difftest_oracle.json`**. Per-suite runs and CLI flags: **[`../difftest/README.md`](../difftest/README.md)**.

 Movement Confidential Assets is an on-chain protocol that enables private fungible token transfers on the Movement blockchain. While transaction senders and recipients remain visible, **transfer amounts are hidden** using homomorphic encryption and zero-knowledge proofs.
 
-The protocol builds on the Aptos Confidential Asset framework, which was originally released under the Apache 2.0 open-source license.

Movement's implementation uses only code that predates the license change, and all production-hardening modifications are clean-room implementations based on published, public-domain cryptography — no post-license-change Aptos code was used or referenced. These modifications include chain ID binding to prevent cross-chain proof replay, SHA3-512 tagged hashing for Fiat-Shamir challenges, a Schnorr-based registration proof to prevent key registration abuse, and **sender auditor hints** for private transfers: an optional opaque byte string (length-capped) that is **hashed into the transfer sigma Fiat–Shamir transcript** so it cannot be altered after the proof is generated, then **emitted** on the on-chain `Transferred` module event.

 ### Non-Infringement Statement
 
 1. **No sigma protocol framework adopted.** Aptos v1.1 introduced 10+ new Move modules (`sigma_protocol*.move`) implementing a generic homomorphism-based prover/verifier. Movement does not use any of these modules. Verification logic remains in `confidential_proof.move` using direct MSM equations.
-2. **Different hash function and construction.** Movement uses SHA3-512 (NIST FIPS 202) with BIP-340 tagged hashing. Aptos uses SHA2-512 with BCS-serialized input structs and a two-level derivation. These are structurally different constructions.
+2. **Different domain separation construction.** Movement uses SHA2-512 with a DST-prefix construction for Fiat-Shamir challenges. Aptos uses SHA2-512 with BCS-serialized `DomainSeparator` input structs and a two-level derivation. The domain separation structures are different.
 3. **Pre-existing code base.** The proof verification structure (MSM equations, gamma batching, deserialization) predates Aptos's November 2025 license change. Movement's modifications add chain ID parameters and switch the hash function; they do not adopt any v1.1 architectural patterns.
 4. **Registration proof is standard Schnorr.** The discrete-log proof of knowledge ($s \cdot H + e \cdot ek = R$) is a textbook Schnorr protocol (1989/1991), not derived from Aptos's `sigma_protocol_registration.move`.

Subject: [PATCH 22/45] Feat/move stdlib formal verification (#308)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Extend the Move stdlib formal verification in Lean 4: add a complete
`vector::index_of` bytecode refinement proof, and add new specification
modules for `error`, `option`, `signer`, `fixed_point32`, and
`bit_vector` with bytecode programs, native models, and refinement
proofs connecting them to the existing Move bytecode interpreter.

## Changes

**`Refinement/Vector.lean` — add `index_of` refinement proof (+927
lines)**

Building on the existing `vector::contains` refinement, adds a full
correctness proof for `vector::index_of` (bytecode index 19 in
`stdModuleEnv`), covering:
- Loop setup (7 steps from `evalProg` to loop header)
- Found path (element match → return `(true, k)`)
- Iteration path (no match → advance to `k+1`)
- Top-level theorems: `vectorIndexOf_returnValues_found` and
`vectorIndexOf_returnValues_notFound`
- Partial `vector::reverse` proof sketch (`sorry`)

Key proof techniques:
- `indexOfLoopFrame` uses `(List.map MoveValue.u64 xs).length.toUInt64`
to match the VM's `step` computation, enabling `rfl` proofs (mirrors the
`contains` pattern)
- `hfail` / `hio` inductive proofs use `suffices` to generalize over the
`indexOf.go` offset parameter, since naive list induction doesn't track
offsets correctly
- `iterN13` outputs `k.toUInt64 + 1` (what the kernel computes) with a
`contains_uint64_succ` conversion in the run chain

**New stdlib specification modules**
- `Std/Error.lean` — canonical error codes and abort-code arithmetic
- `Std/Option.lean` — `option::swap_or_fill` specification and
properties
- `Std/Signer.lean` — signer address extraction
- `Std/FixedPoint32.lean` — fixed-point arithmetic
(`create_from_rational`, `floor`, `ceil`, `round`, `min`, `max`)
- `Std/BitVector.lean` — bit-vector operations (`new`, `set`,
`shift_left`, `is_index_set`)

**Bytecode & native plumbing**
- `Move/Programs/StdPrimitives.lean` — bytecode arrays for
`std::error::canonical` + 13 wrappers and `std::bit_vector::length`,
using the existing instruction set from `Move/Instr.lean`
- `Move/Native/StdPrimitives.lean` — native function models for
`signer`, `fixed_point32`, `option`, and `bit_vector` operations
- `Refinement/StdPrimitives.lean` — refinement proofs connecting
bytecode/natives to specs (proved via `rfl` — the Lean kernel fully
reduces `eval` for concrete non-looping programs)
- `Tests/StdPrimitives.lean` — `native_decide` smoke tests for stdlib
operations

## File changes summary

| File | Description |
|------|-------------|
| `Refinement/Vector.lean` | Add `vector::index_of` refinement proof |
| `Std/Error.lean` | New: error code specs |
| `Std/Option.lean` | New: option swap/fill specs |
| `Std/Signer.lean` | New: signer specs |
| `Std/FixedPoint32.lean` | New: fixed-point arithmetic specs |
| `Std/BitVector.lean` | New: bit-vector operation specs |
| `Move/Programs/StdPrimitives.lean` | New: stdlib bytecode programs |
| `Move/Native/StdPrimitives.lean` | New: stdlib native function models
|
| `Refinement/StdPrimitives.lean` | New: stdlib refinement proofs |
| `Tests/StdPrimitives.lean` | New: stdlib smoke tests |
| `README.md` | Document new modules |
| `lakefile.lean` | Register new modules |

## Testing

- **`lake build`** — passes (exit code 0). Only pre-existing `sorry`
warnings in unrelated files (plus tracked `sorry` in new
`FixedPoint32.lean`, `BitVector.lean`, and the `reverse` sketch).
- **`lake build difftest`** — Lean difftest executable compiles
successfully (2172/2172 jobs).
- **`difftest.sh`** — full differential test pipeline: **227 passed, 0
failed, 0 skipped**.
  - Step 0: Rust corpus verification ✅
  - Step 1: Move VM oracle generation ✅
  - Step 2: Lean evaluator vs oracle ✅

## Key Areas to Review

- **`Refinement/Vector.lean`** lines 814–824 (`indexOfLoopFrame`): uses
`(List.map MoveValue.u64 xs).length.toUInt64` to match the `contains`
pattern, enabling ~20 downstream `rfl` proofs.
- **`hfail` / `hio` proofs** in `vectorIndexOf_returnValues_notFound` /
`_found`: use `suffices` to generalize over the `indexOf.go` offset
parameter.
- **`sorry` declarations** in `Std/FixedPoint32.lean` (2),
`Std/BitVector.lean` (1), and `Refinement/Vector.lean` (`reverse`
sketch) are tracked for future work.

## Type of Change

- [x] New feature (non-breaking change which adds functionality)

+
+## Bug-fix note
+PR #1's `swapOrFill` was incorrect: it always returned `(opt, some' e)` regardless of
+whether `opt` was `some` or `none`. The correct semantics (from the Move source):
+- `opt = none`  → fill it with `e`, return `none'` as the "displaced value" slot
+- `opt = some v` → replace the value, return `some' v` as the displaced value
+
+The return type is `(displaced : MoveOption, updated : MoveOption)`.

Subject: [PATCH 23/45] fix(confidential_proof): resolve batch-MSM gamma index
 collision (#309)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Description

### Background: how batch verification works

A confidential transfer proof contains multiple algebraic equations that
the on-chain verifier must check (e.g. "sender's new balance is
correct", "recipient's amount is correct", "each auditor's ciphertext is
correct"). Checking them one by one is expensive.

**Multi-scalar multiplication (MSM)** batching is an optimization: the
verifier combines all equations into a single equation by multiplying
each one by a different random weight. If the combined equation holds,
all individual ones hold — with overwhelming probability. These random
weights are called **gammas**.

Each gamma is derived as `SHA2-512(rho || i || j)` where **rho** is a
fresh random scalar and **(i, j)** is a unique index pair. The
uniqueness of `(i, j)` is what guarantees every gamma is distinct. If
two different proof relations accidentally receive the same `(i, j)` —
and therefore the same gamma — an attacker could craft values where
errors in one relation cancel out errors in the other, bypassing the
batch check.

### The bug

The function
[`msm_transfer_gammas`](aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move)
assigns gamma index groups as follows:

| Group | Count | `i` index | What it checks |
|-------|-------|-----------|----------------|
| g1 | 1 | 1 | Overall balance consistency |
| g2s | 8 | 2 | Sender's new balance (8 chunks of 16 bits each) |
| g3s | 4 | 3 | Recipient's amount (4 chunks) |
| g4s | 4 | 4 | Transfer amount range proof binding |
| g5 | 1 | 5 | Sender encryption key consistency |
| g6s | 8 | 6 | Current balance (8 chunks) |
| g7s | 4 per auditor | 7+k | Auditor `k`'s ciphertext correctness |
| g8s | 4 | **was 8** | Sender's copy of the transfer amount |

With 2+ auditors, `g7s` for auditor `k=1` uses index `7+1 = 8` — the
same `i` as `g8s`. Two different proof relations get identical gammas,
weakening batch soundness.

With 0 or 1 auditors there is no collision (g7s uses only index 7, g8s
uses 8).

### The fix

`g8s` now uses `i = auditors_count + 7` instead of the hardcoded `8`, so
it is always one past the last `g7s` entry:

- `g7s[k]`: index `(7+k, j)` for `k ∈ [0, n)`
- `g8s`: index `(7+n, j)`

This is a verifier-only change. Gammas are not part of the proof — they
are computed on-chain after the proof is submitted. **No change to proof
generation, no client SDK impact.**

Whitepaper §9 updated with a new "Batch Soundness" subsection
documenting the gamma layout.

## How Has This Been Tested?

- 78 Move unit tests pass (`move_experimental_unit_tests`), including
multi-auditor transfer tests and a new regression test
(`test_g8s_gamma_no_collision_with_g7s`)
- 143 Rust e2e tests pass (`e2e-move-tests -- confidential_asset`),
including `confidential_transfer_with_voluntary_auditors_only` (1-3
auditors) and
`confidential_transfer_asset_auditor_plus_voluntary_auditors` (asset
auditor + 0-3 voluntary)
- The regression test proves the collision was real (`msm_gamma_2(rho,
8, 0) == msm_gamma_2(rho, 1+7, 0)`) and that the fix eliminates it for
all sub-indices

## Key Areas to Review

-
[`confidential_proof.move:1605-1609`](aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move#L1605-L1609)
— the one-line fix in `msm_transfer_gammas`
-
[`confidential_proof.move:2453-2493`](aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move#L2453-L2493)
— regression test proving the collision existed and the fix works
- [`whitepaper.md` §9 Batch
Soundness](aptos-move/framework/aptos-experimental/whitepaper.md) — new
subsection documenting gamma index layout

+### Batch Soundness
+
+Transfer proof verification uses **batched multi-scalar multiplication (MSM)** to check all sigma-protocol relations in a single equation (see [`msm_transfer_gammas`](./sources/confidential_asset/confidential_proof.move)).  Each relation is assigned a random weight (gamma) derived as `SHA2-512(rho || i || j)` where `(i, j)` is a unique index pair.  The per-auditor ciphertext relations (`g7s`) use indices `(7+k, j)` for auditor row `k ∈ [0, n)`, and the sender-amount relation (`g8s`) uses index `(7+n, j)` — i.e. always one past the last auditor row.  This ensures every proof relation receives a distinct random weight regardless of auditor count, preserving the full soundness guarantee of the batch verifier.

-# Plan: Differential testing — Confidential Assets (experimental)
-
-**Active scope (difftest track):** **Move VM ↔ Lean** differential testing (`move-lean-difftest` + `lake exe difftest` + optional merged e2e JSON). Success means **Tier A/B** green and honest progress on **§4.5** (including **Open** rows when claiming “properly difftested” beyond witness-only merged CA rows).
-
-**Parallel scope (formal verification track):** Machine-checked obligations (**L0–L5** in [`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)) — refinement, natives, storage — are **not** implied by difftest green alone. Both tracks are required for a peer-reviewable story that combines **regression evidence** (this doc) and **mathematical validity** (FV plan).
-
-**“Properly difftested *and* formally verified” (repo goal):** means **(C) both** in the FV plan’s sense — **(A)** crypto / proof-level obligations **and** **(B)** bytecode-vs-spec refinement (and higher **L3–L5** wiring as scoped), not difftest alone. See **[`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md) §1.3** for the explicit **(A) / (B) / (C)** table; this differential-testing plan covers the **L1** evidence lane and checklists that feed **(B)** but do not replace it.
-
-This document remains **empirical / finite**: it shows agreement on **recorded oracle cases**, not ∀-quantified correctness (see §2.2).
-
-**Prerequisites:** How difftest works today: [`difftest/README.md`](difftest/README.md), [`lean/README.md`](lean/README.md).
-
-**Move source audit (formal track):** [`CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md`](CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md) — API semantics / hardening notes from static review (not a product security sign-off).
-
-**Completion rubric (“are we done?”):** Use **§4.3** (what “professionally complete” CA difftest coverage looks like) and **§4.4** (tiers **A / B / C** — how to answer without hand-waving).
-
----
-
-## 1. What this approach is
-
-- **Differential testing** here means: run the **same** inputs through  
-  (A) the **real Move VM** (Rust, in-repo), and  
-  (B) the **Lean** small-step evaluator (`AptosFormal.Move.Step` / `eval`),  
-  then compare **outputs** (and aborts / errors) encoded in a shared **JSON oracle**.
-- It is **empirical**, **finite**, and **regression-oriented**: it shows agreement on **the cases you run**, not a **proof for all inputs** or all execution paths.
-
----
-
-## 2. What it **does** and **does not** show
-
-### 2.1 What differential testing **provides evidence for**
-
-| Claim | Strength |
-|--------|----------|
-| On oracle cases, **Lean’s bytecode model + native stubs** agree with **this VM + this compiled bytecode** for the **observed** return values, aborts, and any fields you put in the oracle (e.g. serialized return stack). | **Strong for those cases** — useful to catch transcription bugs, missing instructions, wrong native semantics, endian/layout mistakes. |
-| **Regression detection:** after a Move or Lean change, rerunning the suite flags **drift** before production. | **Strong operational value.** |
-| **Coverage growth:** more cases ⇒ more **confidence** (statistical / engineering), not a **theorem**. | **Inductive evidence only.** |
-
-### 2.2 What it **does not** prove
-
-| Non-claim | Why |
-|-----------|-----|
-| **Correctness for all inputs** | Only finitely many tests; no ∀. |
-| **No bugs** outside the oracle | Untested paths may still be wrong in VM *or* Lean. |
-| **Move source matches bytecode** | Difftest compares **engines on bytecode** (or serialized effects); **compiler correctness** is a separate obligation unless you always regenerate from the same pipeline and trust it. |
-| **Cryptographic security** (e.g. soundness of proofs, absence of forgeries) | Difftest checks **functional equality** on samples, not **security definitions**. |
-| **Lean natives “match the IRTF / independent crypto spec”** | You are checking **VM vs Lean**; both could disagree with an external reference unless you add separate audits or reference tests. |
-
-**One sentence for stakeholders:**  
-Differential testing gives **high-confidence alignment between two implementations on a maintained test set**; it does **not** replace **formal verification** (refinement, invariants, security proofs).
-
----
-
-## 3. Important constraint: Lean must be able to **run** what you test
-
-In this repository, the **Lean side of difftest is not a second Move VM** — it is **`AptosFormal.Move`**’s evaluator over **transcribed** bytecode + **native** implementations in Lean ([`Native.lean`](lean/AptosFormal/Move/Native.lean), `ModuleEnv`).
-
-So **“entire confidential assets codebase under difftest”** still requires **engineering work** for every path you want to cover:
-
-1. **Bytecode** for the involved functions available to Lean (transcribe or generate from disassembly).  
-2. **`MoveInstr` / `Step`** support for every instruction those bytecodes use.  
-3. **Native bindings** in Lean for every native those paths call (or a deliberate **narrow scope** that mocks/stubs natives and only compares a **slice** of behavior — must be documented).
-
-**What you avoid compared to full formal verification:**  
-You do **not** need to write **refinement theorems**, **inductive invariants**, or discharge **proof obligations** in Lean. You **do** still need enough of the **same interpreter stack** that the Lean run is meaningful.
-
-**Rough effort comparison (intuition):**
-
-| Activity | Full verification plan | **This doc (difftest only)** |
-|----------|-------------------------|------------------------------|
-| Transcription + natives + `Step` extensions | Required | **Still required** for VM↔Lean on those paths |
-| Refinement proofs | Required | **Not required** |
-| Timeline for “all CA” | Multi-year (proofs + storage) | **Still large** (natives + globals if testing entrypoints), but **shorter than proof** work and parallelizable as **test oracles** |
-
-If the goal were **“VM-only golden tests”** (no Lean column), that would be a **different** (smaller) project — not the repo’s current **differential** design; we mention it in §9 as optional.
-
----
-
-## 4. Scope — “entire confidential assets codebase”
-
-### 4.1 Move modules (same as formal plan)
-
-| Module | Path (under `aptos-move/framework/aptos-experimental/sources/confidential_asset/`) |
-|--------|--------------------------------------------------------------------------------------|
-| `confidential_asset` | `confidential_asset.move` |
-| `confidential_proof` | `confidential_proof.move` |
-| `confidential_balance` | `confidential_balance.move` |
-| `ristretto255_twisted_elgamal` | `ristretto255_twisted_elgamal.move` |
-| `confidential_gas_e2e_helpers` | `confidential_gas_e2e_helpers.move` (lower priority) |
-
-Plus **transitive** dependencies actually executed (stdlib, `aptos_std`, FA, …) — tracked per test case.
-
-### 4.2 What “coverage” means without proofs
-
-Define **coverage dimensions** explicitly (checklist per milestone):
-
-- [ ] **Functions:** every `public` / `public(friend)` / `entry` you care about appears in at least one oracle.  
-- [ ] **Branches:** happy path + representative **abort** / `none` / verification-failure paths where observable.  
-- [ ] **Natives:** each native on a hot path has at least one case (or is listed as **out of scope** for Lean column).  
-- [ ] **Auditors / optional features:** toggled in dedicated cases.
-
-These bullets are a **minimal inventory checklist**; **§4.3** is the **full professional bar**, and **§4.4** is how to report **which tier (A/B/C)** you satisfy.
-
-### 4.3 Professionally complete confidential-asset difftest coverage (quality bar)
-
-This subsection is **normative for how to talk about “done”** in reviews and when asking assistants: it does **not** redefine Phase 6.x delivery dates, but it **does** define what **“professionally acceptable / complete difftest coverage for CA”** means in industry terms.
-
-**Complete ≠ formal verification.** Completeness here means: **stated scope**, **evidence for every in-scope risk class you claim**, **no undisclosed stubbing on security-critical paths**, and **disciplined oracles** — not “every `entry` in Move has a Lean row tomorrow.”
-
-#### (i) Scope contract
-
-- **In:** which modules and which surfaces (`public` helpers, serializers, crypto primitives, `deserialize_*` edges, …) are claimed by **`move-lean-difftest` + Lean**.
-- **Out:** what is **explicitly not** in this pipeline (typical examples: full economic abuse, gas, liveness, **proof soundness**, “Lean matches RFC” without a third reference).
-- **Elsewhere:** what is covered only by **VM-only** or **e2e** (see **§7.0**) — still valuable, but **not** “VM↔Lean difftest” for those rows.
-
-Until **in / out / elsewhere** is written (inventory + this doc), “complete” is undefined.
-
-#### (ii) Equivalence-class coverage (not row count)
-
-For every **in-scope** observable API, professionally acceptable coverage includes **representatives per class**, not only happy paths:
-
-- **Lengths / layouts:** empty, sub-min, exact boundary, over-long; `Option` / abort outcomes recorded in the oracle where observable.
-- **Encodings:** `to_bytes` / `from_bytes`, compress / decompress, wrong wire layouts.
-- **Algebra (where claimed):** identities, inverses, relations that the math guarantees on stated domains; assignment vs functional forms when both exist.
-- **Chunking:** parameterized or systematic coverage over chunk indices / amount patterns (not only a few hand-picked constants).
-- **Cross-representation:** same semantic value built two supported ways (e.g. constructors that should agree on `balance_equals` / `balance_c_equals` / `is_zero`).
-
-#### (iii) Cryptographic primitives
-
-- **Vectors:** known-answer or **independent** gold vectors where feasible — not only self-consistency between VM and a second engine.
-- **Invalid inputs:** wrong lengths, non-canonical encodings if the API distinguishes them.
-- **Optional:** small **seeded-random** corpora VM↔Lean for hot paths (still finite; document seeds and scope).
-
-#### (iv) `confidential_proof` — staged honesty
-
-- **`deserialize_*`:** structure / length classes leading to `None` vs `Some`; if you claim deserialization correctness, add a **corpus of valid serialized proofs** from the real prover or harness (versioned bytes).
-- **`verify_*`:** either **VM-only / e2e** with a large, versioned accept/reject corpus (**§7.0**), or **VM↔Lean** only when Lean actually runs the same verification semantics. **Undocumented `ldTrue` stubs on `verify_*` are smoke, not “complete verify difftest.”**
-
-#### (v) `confidential_asset` transactional surface
-
-Professional **product** confidence for the asset module usually requires a **scenario matrix** (register, deposit, withdraw, transfer, rotate, normalize, auditor variants, failure modes) with **observable oracles** (state, events, abort codes) — typically **e2e / integration** (**§7.0**, **§7.1**). The **`move-lean-difftest`** JSON column may cover only **globals-free slices** (**Option B**); that gap must stay **explicit** in [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md).
-
-#### (vi) Second-column (Lean) fidelity
-
-Document, per row or per path, one of:
-
-- **Bytecode + natives** intended to track production semantics, or  
-- **Stub / trivial bytecode** that matches the VM **only on that oracle input** (must be obvious in `Programs/Confidential*.lean` + inventory).
-
-Stakeholders should never have to guess which applies.
-
-#### (vii) Process (non-negotiable)
-
-- **Deterministic** oracle regeneration from pinned toolchain / features.  
-- **CI** runs VM → JSON → Lean for all non-`skip_lean` rows relevant to CA.  
-- **Inventory + changelog** when scope or stubs move.  
-- **Triage rule** when VM and Lean disagree (which column is ground truth for regression).

-### 4.4 Answering “Are we done with confidential-asset difftest coverage?”
-
-Use **named tiers** so answers are not ambiguous:
-
-| Tier | Meaning | Typical evidence |
-|------|---------|------------------|
-| **A — Pipeline complete (declared slice)** | Every **VM↔Lean** row in the maintained oracle(s) passes; every symbol the inventory marks as **VM↔Lean** for CA suites either has a representative case **or** an explicit **waived / blocked** note; no **undocumented** stubbing. | Green `lake exe difftest` on pinned JSON; [`confidential_assets.md`](difftest/inventory/confidential_assets.md) matches reality. |
-| **B — Professionally strong** | **Tier A** plus **§4.3 (ii)–(vii)** to a degree the team signs off on (equivalence classes, vectors where promised, proof/entrypoint staging honest, Lean fidelity documented). | Reviewed coverage matrix + external vectors where claimed. |
-| **C — Product-complete CA** | **Tier B** plus **transactional / full `verify_*`** evidence the product relies on — usually **§7.0 e2e** + optional export (**§7.1-B**), **not** `move-lean-difftest` alone unless Lean store + FA + proof natives exist. | E2e suite + optional merged oracle; documented Lean witness limits. |
-
-**How to answer in one sentence**
-
-- If only **Tier A** is satisfied: **“Difftest is green for the declared VM↔Lean oracle slice; CA as a whole is not ‘fully difftested’ unless Tier B/C criteria are separately claimed.”**  
-- If **Tier B** is satisfied: **“CA difftest meets the professional bar we documented in §4.3–4.4.”**  
-- **Never** say “fully difftested” for all of CA without stating **which tier** and pointing at **§7** for entrypoints / full verification.
-
-**Assistant / reviewer default:** when the user asks **“Are we done?”**, respond with **current tier (A/B/C)** + **one concrete gap** from **§4.3** or the inventory (highest risk first).
-
-**Important:** **Tier C is not a single deliverable** you can “finish” in one change set. Treat **§4.5** as the living checklist until the team signs off or explicitly narrows scope.
-
----
-
-### 4.5 Traceability — “Full” (Tier C) vs this repository (living checklist)
-
-Use this table to avoid arguing from slogans. **Update the Status column** when work lands.
-
-| §4.3 / §4.4 requirement | Where it lives in-repo | Typical status (check in PRs) |
-|-------------------------|--------------------------|--------------------------------|
-| **Tier A:** VM↔Lean harness rows green | `lake exe difftest` on `difftest_oracle.json` (local) / merged in CI | **Track:** must stay green on every CA-touched PR. |
-| **Tier A:** merged harness + e2e fragment green | [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml); [`difftest.sh`](difftest.sh) with `DIFTEST_MERGE_CA_E2E=1` | **Track:** CI runs merge + Lean on `difftest_ci_merged.json`. |

-| **§4.3 (ii)** equivalence-class matrix written down | [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md) §8–10 | **Ongoing** — extend as suites grow. |
-| **§4.3 (iii)** independent / gold crypto vectors | [`difftest/corpora/confidential_assets/`](difftest/corpora/confidential_assets/) + **`cargo run -p move-lean-difftest -- verify-corpora`** (Rust; **`difftest.sh` \[0\]** / **`.github/workflows/formal-difftest.yaml`**) | **Partial** — registration FS + SHA2-512 digest + BP DST (SHA3-512) + **fixed sigma wire layouts** (`deserialize_sigma_*.hex`, **1152 / 1216 / 1792 / 1920 / 2048 / 2176 / 2304 / 2432 / 2560 / 2688 / 2816 / 2944 / 3072 / 3200 / 3328 / 3456 / 3584 / 3712 / 3840 / 3968 / 4096 / 4224** B transfer extension classes) + **auditor serializer wires** (EK **32 / 64 / 96 / 128 / 160 / 192** B; pending amounts **256 / 512** B zero rows + **256** B VM-pinned **`u64(1)`** no-rand + **512** B actual-width zero + **512** B mixed two-pending wires in **both** vector orders: zero-then-**`u64(1)`** and **`u64(1)`**-then-zero + **768** B mixed **actual**-zero + **`u64(1)`**-pending in **both** orders) checked vs Rust verifier + Lean defs/theorems; extend with more Ristretto/BP/third-party vectors when claiming broader crypto alignment. |

Still **open** for full Lean `eval` replay of **`deserialize_*`** + cryptographic `verify_*` alignment. |
-| **§4.3 (iv)** Lean runs real `verify_*` on proof blobs | `AptosFormal.Move.Native` + `Programs/Confidential` | **Open / formal-plan scale** — not implied by `lake exe difftest` today. |
-| **§4.3 (v)** Lean replays FA + `borrow_global` + entrypoints | `Move.State` / store model | **Open** — see **§7.1-A/C** and formal verification plan. |
-| **§4.3 (vi)** stub vs real bytecode documented per CA row | `Programs/Confidential.lean` + inventory + [`difftest/inventory/confidential_native_matrix.md`](difftest/inventory/confidential_native_matrix.md) | **Ongoing** — expand comments when adding indices; native matrix tracks **stdlib crypto** vs Lean. |
-| **§4.3 (vii)** triage rule + oracle regen discipline | `difftest/ORACLE_CHANGELOG.md`, `difftest/README.md` | **Track** — keep current. |
-
-**Bottom line for assistants:** **“Full difftests for confidential assets” (Tier C)** means **this table’s Tier-C rows + Tier B evidence** are satisfied **and** the team accepts **Lean witness limits** until the **Open** rows close. **Do not** claim Tier C solely from harness row count.

----
-
-## 5. Architecture extensions (Rust + Lean + schema)
-
-### 5.1 Rust (`move-lean-difftest`)
-
-- New suite(s), e.g. `confidential` or `confidential_balance` / `confidential_proof` / … registered in [`difftest/src/suites/mod.rs`](difftest/src/suites/mod.rs) (pattern: [`vector.rs`](difftest/src/suites/vector.rs)).
-- **Load** compiled packages that include `aptos_experimental` + dependencies (same style as existing suites: `InMemoryStorage`, publish, invoke).
-- For each case: build **args**, run VM, serialize **results** (return values, abort code, optional **event** bytes if needed) into the oracle JSON.
-
-### 5.2 JSON schema
-
-- Extend [`schema.rs`](difftest/src/schema.rs) / Lean [`DiffTest/JsonParser.lean`](lean/AptosFormal/DiffTest/JsonParser.lean) if CA cases need richer payloads (large `vector`, multiple return values, structured errors).
-- Version the schema if old oracles must keep working.
-
-### 5.3 Lean (`lake exe difftest`)
-
-- Extend [`DiffTest/Runner.lean`](lean/AptosFormal/DiffTest/Runner.lean) (or a sibling) to:
-  - parse CA cases;
-  - map case → **`ModuleEnv`** function index + **decoded `MoveValue` args**;
-  - run `eval` / `evalProg` with sufficient **fuel**;
-  - compare to oracle (same equality strategy as vector/BCS/hash).
-
-### 5.4 `ModuleEnv` for CA
-
-- Add a **`caModuleEnv`** (or extend `stdModuleEnv`) in new `Programs/Confidential*.lean` files: function table + **native dispatch** aligned with what CA bytecode calls.
-- **No refinement files required** — only enough definitions for **evaluation** to complete or abort consistently.
-
----
-
-## 6. Phased plan (difftest-only)
-
-**Numbering:** The roadmap defines **Phases 0–5 only** (subsections below). **There is no Phase 6.** Later headings **§7–§9** are **other document sections** (evidence wording, optional VM-only note, maintenance) — they are **not** “Phase 7 / Phase 8 / Phase 9.” If your editor shows “Phase 5” followed by “7,” that jump is **section** numbering (6 = phased plan, 7 = evidence), not a missing delivery phase.
-
-### 6.0 Honest scope — what “implemented” means here
-
-The **calendar-style** subsections below (especially Phase **2–4** timelines) describe **breadth of coverage** that can take many weeks. What is **actually in the tree** today is narrower:
-
-| Phase | In repo today | Still open (same phase number) |
-|-------|----------------|--------------------------------|
-| **1** | CA smoke in the harness + Lean + CI path | — |
-| **2** | Many `confidential_balance` VM cases + Lean **stub** `ModuleEnv` matching VM on those oracle rows | Full bytecode transcription / evaluator paths for every hot native; every public helper in §4 inventories |
-| **3** | Constants + empty `deserialize_*`; **registration FS golden `msg`** (199 B, DST prefix + transcript) VM↔Lean via `TranscriptAlignment`; deterministic Schnorr roundtrip VM-only in harness; SHA3-512 on BP DST VM↔Lean; SHA2-512 on registration FS digest VM↔Lean | **Friend-only** `verify_registration_proof` on **production** bytecode still lives in **e2e** (`§7.0`), not in `head.mrb` harness. **Lean:** no executable Ristretto verification in `eval` yet — `verify_*` on full proof blobs and **Bulletproof verify end-to-end in Lean** remain **formal-verification-track** scope ([`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)), not `lake exe difftest`. |
-| **4** | **Option B** layer smoke + **Option B+**: `global_resource_smoke` suite — real `borrow_global` on a published `has key` resource at `@std` in the **same** JSON oracle as other suites | **FA / fungible store / `confidential_asset::register` entrypoints** in VM↔Lean JSON: still **§7.0 e2e** + **merged fragment** (`skip_lean` rows). **Lean note:** `MachineState` + `GlobalResourceKey` exist; FA + CA globals in `eval` are not implemented. |
-| **ElGamal** | Suite `confidential_elgamal`: VM oracles for **non–`test_only`** `public` APIs; Lean stubs indices 20–31 plus **`ciphertext_add_assign` / `ciphertext_sub_assign`** witnesses at indices **53–54** | Field access on `CompressedCiphertext` internals (no public getters); `#[test_only]` keygen / `new_ciphertext*` |
-| **5** | `schema_version`, `ORACLE_CHANGELOG.md`, regen workflow via script + CI | Optional nightly fuzz; no automated “regen oracle on every CA API change” beyond developer/CI runs |
-
-So: **infrastructure and a real differential slice are done**; **full Phase 2–4 depth from the tables is not.** Section **§4.2** checkboxes stay open until coverage catches up.
-
-### Phase 0 — Inventory and case design (**complete**)
-
-**Deliverables (done)**
-
-- Hub methodology + suite registry: [`difftest/INVENTORY.md`](difftest/INVENTORY.md).
-- Confidential assets + template tables: [`difftest/inventory/`](difftest/inventory/) (`confidential_assets.md`, `move_framework_template.md`).
-- Rust harness: `--list-suites`, dynamic `--suite` help / errors from `all_suites()`; [`difftest.sh`](difftest.sh) supports `--list-suites` (skips Lean).
-- **Discipline:** VM oracle is ground truth per run; mismatches are investigated — Move code is **not** assumed correct; oracles are not hand-edited to force Lean passes.
-
----
-
-### Phase 1 — Harness + one end-to-end smoke case (2–6 weeks)
-
-**Deliverables**
-
-- [x] One Rust-generated oracle for **one** CA-invoking scenario (simplest: helper that only touches balance + crypto already partially modeled, or **pure** deserialization path).
-- [x] Lean runner executes **that** case; `difftest.sh` forwards `--suite confidential` (meta id expanding to balance + proof + layer smoke).
-- [x] CI job: generate oracle + run Lean — [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml) (path-filtered); default policy remains **generated** oracle (see [`difftest/README.md`](difftest/README.md)).
-
-**Success criterion:** Green CI on that single case.
-
----
-
-### Phase 2 — `confidential_balance` coverage (4–10 weeks)
-
-**Deliverables**
-
-- [x] Oracles for **public** helpers: zero balance, compress/decompress roundtrip, add (fixed inputs), serialization size checks, chunk constants, `Option` deserialization edge cases, etc.
-- [x] Lean: **native stubs** in `AptosFormal.Move.Programs.Confidential` aligned with VM outputs on oracle inputs (not full bytecode transcription for every path — see inventory skip list).
-
-**Success criterion:** Suite runs **N** cases; documented list of **skipped** functions and why — [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md).
-
----
-
-### Phase 3 — `confidential_proof` (8–20 weeks, parallel by verifier)
-
-**Sub-tracks**
-
-- [x] **Registration transcript (partial):** harness rows **`test_registration_fs_message_golden_move`** / **`test_registration_fs_message_golden_move_second`** return the **199-byte** FS `msg` (DST prefix + transcript) for the two formal goldens; Lean uses **`TranscriptAlignment.expectedRegistrationFsMsgMoveGolden`** / **`expectedRegistrationFsMsg2`** (same bytes as [`formal_goldens_registration.move`](../aptos-experimental/tests/confidential_asset/formal_goldens_registration.move)). Framework-vs-helpers rows **170** / **173** VM-pin **`registration_fs_message_for_test`** on each scenario. This tightens **transcript** alignment; it is **not** a `verify_registration_proof` **curve** check in `eval`.
-- [x] **Harness Schnorr roundtrip:** `difftest_registration_helpers::registration_roundtrip_vm` (VM). Lean column: **bool stub** until Ristretto/group operations are executable in `AptosFormal.Move` natives.
-- [x] **Partial — production curve verify in harness JSON:** `verify_registration_proof_for_difftest` + deterministic prover on the **`registration_roundtrip_vm`** fixture (`test_registration_proof_framework_deterministic_verify_roundtrip`, Lean **171** = same `execVerifyRegistrationProof` column as **35**). Full **`register` → friend `verify_registration_proof`** on transactions remains **e2e** canonical (`§7.0`).
-- [ ] **Transfer / withdraw / normalize / key rotation in harness+Lean:** same as above; **e2e merged oracle** records real `verify_*` on transactions (`skip_lean`).
-
-**Native-heavy areas:** range proof / sigma / Bulletproofs — **VM↔Lean equality on full verify** would require Lean natives matching Aptos Bulletproofs + Ristretto batch interfaces; that is **orthogonal** to this difftest roadmap (treat as proof or reference-library work).
-
----
-
-### Phase 4 — `confidential_asset` entrypoints (depends on Phase 2–3 + storage)
-
-**Challenge:** Entrypoints touch **global storage** and **FA**; current `Move.*` model **omits globals** (see [`Move/README.md`](lean/AptosFormal/Move/README.md)).
-
-**Options (pick explicitly):**
-
-| Option | Difftest “entire codebase” meaning |
-|--------|--------------------------------------|
-| **A. Extend Lean state with a minimal store** | True VM↔Lean on entrypoints; **large** model work, still **no proofs**. |
-| **B. Test only `fun` paths** that do not need globals | Partial “entire” — document gap. |
-| **C. VM column only** for entrypoints; Lean for **internal** slices | Hybrid; not pure differential on entrypoints. |
-
-**Chosen for this repo (current track): Option B** for `confidential_asset` **module paths**, plus **§7.1-B** for **full stack (FA + globals + `verify_*`)** evidence: the **merged** oracle [`difftest_ci_merged.json`](difftest/difftest_ci_merged.json) (CI) = `move-lean-difftest` harness + **e2e** [`OracleFragment`](../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs) rows with **`skip_lean: false`**, so Lean runs the **witness** bytecode paths mapped in `Runner.lean` (not full FA + real `verify_*` replay in Lean). E2e success rows include **`bool` `true`** as a compact witness that the scenario’s VM checks passed.
-
-**New harness suite:** `global_resource_smoke` — `borrow_global` on a resource published at `@std` via BCS from Rust (not FA).
-
-The plan should **name the chosen option** in the README for this suite.
-
----
-
-### Phase 5 — Regression and maintenance
-
-**Deliverables**
-
-- [x] Oracles regenerated on compiler / CA **API** changes; changelog entry when oracle format bumps — [`difftest/ORACLE_CHANGELOG.md`](difftest/ORACLE_CHANGELOG.md) + `schema_version` in JSON (`CURRENT_SCHEMA_VERSION` in Rust).
-- [ ] Optional: nightly **fuzz**-generated cases (VM only first; add Lean when safe). *Not implemented in CI;* track as a separate harness if random/property cases are needed beyond `move-lean-difftest`’s fixed vectors.
-
----
-
-## 7. Stretch scope — three requested tracks (dependency map + what already exists)
-
-This section records **gaps for `move-lean-difftest` + Lean**, and **where the repo already runs the heavier VM story** (transactional CA + real proof verification on bytecode).
-
-### 7.0 **Already in tree:** transactional VM, `register`, and full `verify_*` / `verify_registration_proof` paths
-
-**Location:** [`aptos-move/e2e-move-tests/src/tests/confidential_asset_e2e.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e.rs)
-
-**What it does (VM column only — not `lake exe difftest`):**
-
-- Builds **`aptos-experimental`** with **`test_mode = true`** and injects **all `0x7`** modules (plus a **test-mode `0x1`** stdlib graph) into a **`MoveHarness`** so `#[test_only]` helpers such as **`prove_registration`** are available.
-- Re-seeds **`FAController` / `init_module_for_testing`** so on-disk layout matches injected `confidential_asset` bytecode.
-- Drives **real entry transactions**: **`register`** (which calls **`verify_registration_proof`** on the **friend** path), **`deposit`**, **`rollover`**, **`confidential_transfer`**, **`withdraw_to`**, **`rotate_encryption_key`**, freeze/auditor scenarios, etc., with **valid** proof payloads assembled in Rust / Move helpers inside that file.
-
-**How to run (from repo root):**
-
-```bash
-# All tests whose names match the module filter (can be slow; some environments need a larger stack).
-RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests confidential_asset_e2e -- --test-threads=1
-```
-
-Example **single** scenario (register + deposit + rollover + gas profile hook):
-
-```bash
-RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests tests::confidential_asset_e2e::confidential_asset_register_deposit_rollover_and_gas -- --exact --test-threads=1
-```
-
-**Relation to `move-lean-difftest`:** this is the **canonical** answer today for “**full VM** behavior including globals, FA, and **`confidential_proof::verify_*`** on real structs.” It does **not** produce the **JSON oracle** consumed by Lean; bridging **e2e → `difftest_oracle*.json`** (or extending Lean to replay harness state) remains future work (see **7.1-B** / **7.2**).
-
-### 7.1 `confidential_asset` in **`move-lean-difftest`** (still Option B)
-
-**Why `move-lean-difftest` alone is still limited:** `register`, `deposit_to`, … **`acquire`** store + FA; the harness uses **`InMemoryStorage` + `execute_loaded_function`**, not a full Aptos transaction. **`head.mrb`** omits **`#[test_only]`** symbols, so **`register_for_testing`** etc. are **not** in that compiler graph.
-
-**Forks if you want VM↔Lean on entrypoints here:**
-
-| Track | Idea | Lean column? |
-|-------|------|----------------|
-| **7.1-A** | Extend difftest session with **minimal global store + FA** (or share harness code with e2e) | After `AptosFormal.Move.State` matches |
-| **7.1-B** | Emit **JSON** from **e2e** (or `aptos move test`) for VM-only rows, optional `lake exe` skip | VM-only until Lean store |
-| **7.1-C** | **Option A** from Phase 4 (§6): full Lean container store + FA | Largest Lean surface |
-
-**Suggested order:** treat **§7.0** as source of VM truth for entrypoints → add **7.1-B** export or **7.1-A** only if you need the **same JSON pipeline** as vector/BCS suites.
-
-### 7.2 `confidential_proof` in **`move-lean-difftest`** vs **e2e**
-
-**On real bytecode today:** **`verify_registration_proof`** runs inside **`confidential_asset::register`** in **§7.0** tests. **`verify_withdrawal_proof` / `verify_transfer_proof` / …** run on **`withdraw_to` / `confidential_transfer` / `rotate_*`** paths in the same file.
-
-**On `move-lean-difftest` today:** only **release-visible** smoke (`deserialize_*` on empty, constants). Friend-only **`verify_registration_proof`** and **`prove_*`** are **not** in **`head.mrb`**.
-
-**Lean:** still **no** faithful sigma + Bulletproofs over full proof blobs in `AptosFormal.Move.Programs.Confidential`; stubs only match the **narrow** oracle cases.
-
-**Suggested order:** optional **JSON export** from e2e scenarios → **VM-only** rows in schema (§9) → long-term **Lean natives** or bytecode transcription (**7.3**).
-
-### 7.3 “True” bytecode parity in Lean (whole CA modules, not stub `ModuleEnv`)
-
-**What it means:** For each function under test, **disassembled** `MoveInstr` in Lean (or generated from the same compiler pipeline), **`Step`** coverage for **every** instruction, and **every** `native` on those paths bound in `AptosFormal.Move.Native` with semantics matching the VM — **then** `eval` against `realModuleEnv`-style tables instead of **`Programs/Confidential` stub `FuncDesc`**.
-
-**Why it is large:** `confidential_proof.move` alone is thousands of lines with many natives (Ristretto, SHA3, Bulletproofs, …). This is **orthogonal** to “no refinement proofs” — you still need a **complete interpreter slice**.
-
-**Suggested order:** automate **bytecode export** for one **`confidential_balance`** `public fun` already in the oracle → prove **`Step`** + natives for **that** function end-to-end → repeat module-by-module. CA-wide parity is a **program**, not one task.

-
-## 8. Appendix — Evidence summary (for audits / leadership)
-
-**You can honestly claim:**
-
-- “On **{N}** automated cases, the **Lean bytecode evaluator** and the **Aptos Move VM** **agreed** on outputs for **{listed}** confidential-asset paths, revision **{git SHA}**, toolchain **{versions}**.”
-
-**You should not claim:**
-
-- “Confidential assets are **formally verified**.”  
-- “**All** inputs behave correctly.”  
-- “**Security** of the cryptographic protocol follows from difftest.”
-
-**Optional one-liner:**  
-Differential testing is **continuous alignment evidence** between two implementations; refinement proofs would be **mathematical obligation** — orthogonal.
-
----
-
-## 9. Appendix — Optional: VM-only oracle suite (out of scope for “difftest” name)
-
-If the team wants **fast** coverage **without** extending Lean:
-
-- Maintain **JSON (or Move test) goldens** produced **only** by the VM.  
-- That is **not** “Move ↔ Lean differential testing” in this repo’s sense; it is still valuable as **VM regression**.  
-- Can be a **Phase 0** deliverable feeding later VM↔Lean cases (same inputs, once Lean is ready).
-
----
-
-## 10. Appendix — Document maintenance
-
-- Update **Phase** status and **option A/B/C** for `confidential_asset` when decided.  
-- When CA difftest **scope or stubs** change, update **§4.3–4.4** if the **completion rubric** or **tier definitions** shift; keep [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md) aligned so **“which tier are we?”** stays answerable from the repo.  
-- Link this file from [`formal/README.md`](README.md) if you want discoverability.
-
----
-
-## 11. Appendix — “Full stack in JSON / full verify in Lean”: what this repo does **not** promise
-
-Requests sometimes bundle: **FA + globals + `borrow_global`**, **real `verify_*` on non-trivial proofs in the Lean column**, **full Bulletproof verification in Lean**, and **machine-checked refinement of `verify_registration_proof` inside `lake exe difftest`**.
-
-| Ask | In-repo status |
-|-----|----------------|
-| FA + CA entrypoints + real proofs **in the VM oracle** | **Yes (VM column + merged oracle):** [`confidential_asset_e2e_oracle_impl.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs) scenarios + merge into `difftest_ci_merged.json`. Lean **compares** mapped rows (`skip_lean: false`) on **witness** programs, not the full transactional stack. |
-| FA + the same in **Lean `eval`** | **No:** would require a large `AptosFormal.Move` store + FA + confidential bytecode + natives — see [`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md). |
-| **Full Bulletproof verify in Lean** (matching VM bit-for-bit on proof blobs) | **No:** not implemented; difftest checks **SHA3-512** on the BP **DST string** and **SHA2-512** on FS digests, plus other **narrow** stubs only. |
-| **Refinement proof** of registration inside the difftest runner | **No:** registration **math** lives under `AptosFormal.Experimental.ConfidentialAsset.Registration.*` (e.g. `SchnorrCompleteness`, `TranscriptAlignment`); `lake exe difftest` is **operational** alignment on oracle rows, not a proof obligation discharge. |
-| **`borrow_global` in harness JSON** | **Yes (VM↔Lean):** suite `global_resource_smoke` (`difftest_global_smoke.move` + published `Counter`). |
-
-**Local CI mirror:** `./aptos-move/framework/formal/difftest.sh` (harness + Lean); with `DIFTEST_MERGE_CA_E2E=1`, e2e export + merge + Lean on `difftest_ci_merged.json` (same as [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml)).

-# Plan: Formal verification for Confidential Assets (experimental)
-
-**Dual-track program (confidential assets):**
-
-1. **Difftest / alignment** — milestones, merged e2e oracle, and **§4.5 checklist** (“properly difftested” in the repo’s sense): **[`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md)**.
-2. **Formal verification** — **L0–L5** obligations, refinement, and proof hygiene: **this document**.
-
-Neither track replaces the other: difftest catches **VM↔model drift** on goldens; FV is what supports **“Move implements the intended math”** claims for reviewers.
-
-**Program bar (“properly difftested *and* formally verified”):** both tracks are required, in the following sense (see **§1.3**):
-
-- **(A) Crypto / proof obligations** — machine-checked properties of the **intended math** (transcripts, hashes, curve / proof interfaces, registration soundness-style lemmas, …), largely **L0** and crypto-facing workstreams here.
-- **(B) Bytecode vs spec** — connecting **Lean `Move` execution** (and eventually module wiring / storage) to those specs via **refinement** and **`eval`**-level proofs (**L2–L5** as applicable), not only oracle agreement on finite rows.
-- **(C) Both (A) and (B)** — this repo’s **completion** goal for CA formal work is **(C)**: difftest and corpora are **necessary regression evidence**; **(A)** and **(B)** together are what “formally verified” means here, unless a milestone explicitly scopes down (e.g. oracle-only L1 for a slice).
-
----
-
-This document is a **roadmap** for extending the **`AptosFormal`** stack so that **confidential assets** (`aptos_experimental::confidential_*` and dependencies) can be **machine-checked** with a clear statement of what is proved against what. It is written for engineers and proof engineers working in `aptos-move/framework/formal/`.

-## 1. Definitions
-
-### 1.1 “Confidential assets” in this repo
-
-**In scope (Move sources, relative to repo root):**
-
-| Layer | Module(s) | Path |
-|-------|-----------|------|
-| Asset controller | `aptos_experimental::confidential_asset` | `aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_asset.move` |
-| Proofs / verification | `aptos_experimental::confidential_proof` | `…/confidential_proof.move` |
-| Encrypted balances | `aptos_experimental::confidential_balance` | `…/confidential_balance.move` |
-| Twisted ElGamal | `aptos_experimental::ristretto255_twisted_elgamal` | `…/ristretto255_twisted_elgamal.move` |
-| Test / harness helpers | `aptos_experimental::confidential_gas_e2e_helpers` | `…/confidential_gas_e2e_helpers.move` |
-
-**Transitive dependencies (must be in scope for *full* entrypoint verification):**
-
-- `aptos_std::ristretto255`, `aptos_std::aptos_hash`, Bulletproofs / range-proof APIs as used from Move
-- `std::bcs`, `std::vector`, `std::option`, `std::signer`, …
-- **Fungible asset / object / dispatchable FA** paths used by `confidential_asset` entrypoints
-- Any **governance / allow-list** modules actually invoked
-
-### 1.2 What “formally verified” means here (levels)
-
-Use **explicit levels** so stakeholders do not confuse them:
-
-| Level | Meaning | Example |
-|-------|---------|---------|
-| **L0 – Spec only** | Pure Lean `Prop` / functions aligned to Move **source**; no bytecode. | Today: `AptosFormal.Experimental.ConfidentialAsset.Registration.*` for `verify_registration_proof` math + transcript goldens. |
-| **L1 – Differential** | Real VM vs Lean **evaluator** on shared oracles; **not** a proof. | Today: `vector`, `bcs`, `hash`, **`global_resource_smoke`**, **`confidential_*`** harness suites + **merged CA e2e** JSON in CI; many merged CA rows use Lean **witness** stubs (constant returns) — see differential plan **§4.5 / §11**. |
-| **L2 – Bytecode refinement (local)** | For a **single** function or closed snippet: transcribed `CodeUnit` in Lean + `Move.step`/`eval` agrees with a **Lean spec** (possibly `sorry`-free under hypotheses). | Today: `Refinement/Core.lean`, `Refinement/Vector.lean` for stdlib-shaped code. |
-| **L3 – Bytecode + module wiring** | Correct `ModuleEnv`, constant pool, **native dispatch**, `Call`/`Ret` across **multiple** functions in one compilation unit. | Not done for CA. |
-| **L4 – Resource / global state** | Model **`borrow_global`**, `move_to`, signer, **FA stores**; proofs about **entrypoints** that touch storage. | **Not** in current `Move.Instr` “omitted” set; largest extension. |
-| **L5 – End-to-end chain** | L4 + **compiler correctness** (Move source ↔ bytecode) or a **trusted** disassembly pipeline. | Optional; separate project from “verify this branch’s Move”. |
-
-The **completion scope** tag **(A) / (B) / (C)** (crypto vs bytecode-vs-spec vs **both**) is spelled out in **§1.3**; the levels above map onto those tags (e.g. **(A)** ↔ L0-heavy crypto, **(B)** ↔ L2–L5, **L1** ↔ difftest evidence).
-
-**“All of confidential assets formally verified”** in a **single milestone** is not realistic. This plan targets **L0 already in progress**, then **L1 → L2 → L3** in priority order, with **L4** as a **branching** track when entrypoint proofs are required.
-
-### 1.3 Program completion scope: **(A)**, **(B)**, and **(C)**
-
-Stakeholders sometimes split “formal verification” into *crypto proofs* vs *implementation proofs*. **For confidential assets in this program, “formally verified” means both:**
-
-| Tag | Meaning | Typical artifacts / levels |
-|-----|---------|------------------------------|
-| **(A)** | **Crypto / proof obligations** — the Move-facing **math and protocol** story is proved (or clearly axiomatized) in Lean **independently of** “does `eval` replay this bytecode.” | **L0** modules (e.g. registration transcript / Schnorr / hash lemmas), future BP / Ristretto specs as claimed in Workstream A. |
-| **(B)** | **Bytecode vs spec** — the **Lean Move model** (`Move.step` / `eval`, `ModuleEnv`, natives, later globals/FA) is shown to **implement** or **refine** the relevant specs on chosen units or entrypoints. | **L2** `Refinement.*`, **L3** module wiring, **L4** resources / FA, **L5** optional compiler-trust story. |
-| **(C)** | **Both** — the **intended bar** for “CA is formally verified” in repo documentation and planning: **(A)** without **(B)** leaves an execution gap; **(B)** without **(A)** can match wrong crypto. | Delivered incrementally per milestone; **L1 difftest** is **evidence**, not a substitute for **(C)**. |
-
-**Difftest (L1)** remains **essential** for **regression and alignment**, but it does **not** by itself satisfy **(A)** or **(B)**; it supports **(B)** by pinning concrete behaviors and **(A)** indirectly via goldens, not by proving ∀-properties.

-## 2. Current baseline (move-lean / formal tree)
-
-### 2.1 Already present
-
-- **`AptosFormal.Move.*`**: partial bytecode instruction set, `Step`/`run`/`eval`, `ModuleEnv`, **`MachineState`** with abstract globals (`GlobalResourceKey`); **no** full `StructTag`+FA signer semantics, variants, or closures (see [`Move/README.md`](lean/AptosFormal/Move/README.md), [`difftest/STUB_POLICY.md`](difftest/STUB_POLICY.md)).
-- **`AptosFormal.Native`**: BCS (selected monomorphizations), `sha3_256`, vector-related natives — **not** CA’s full native surface.
-- **`AptosFormal.Refinement`**: small `rfl` programs + **`vector::contains`** and **`vector::index_of`** universal proofs for curated bytecode; **`std::error`** (all 14 functions) and **`bit_vector::length`** via `rfl` in `Refinement/StdPrimitives.lean`.
-- **`AptosFormal.Refinement.Confidential`** (**L2 / track B**): `eval confidentialModuleEnv …` agrees with **Move-constant** specs for CA harness rows — **`confidential_balance`** chunk / zero-serialization **`u64`** views (**0–4**), **Bulletproofs** UTF-8 DST + **`u64(16)`** num-bits + **SHA3-512** digest (**14** / **15** / **34**, full **`vector`** where applicable), **Fiat–Shamir sigma DST** getters (**43–46** / **51**, full **`mvU8Wire`** vs **`Programs.Confidential.fiat*SigmaDstBytes`**), **registration FS golden `msg`** (**38**, **`mvU8Wire`** vs **`Programs.Confidential.registrationFsMsgGoldenMoveBytes`**), **registration SHA2-512 goldens** (**174** / **175**, **`mvU8Wire`** vs **`TranscriptAlignment.expectedTaggedHashGolden{,2}.toList`** via **`Programs.Confidential.registrationSha2_512Golden*MoveBytes`**), **sigma wire length** **`bool(true)`** indices **128–130** and transfer-extension **131** / **133** / **135** / **137** / **139** / **141** / **143** / **145** / **147** / **149** / **151** / **153** / **155** / **157** / **159** / **161** / **163** / **165** / **167** (through **4224** B), FA stub **`faWriteBalance` + `faReadBalance`** round-trip (**169**, **`u64(9999)`** from empty **`faBalances`**), registration FS framework **`bool(true)`** (**170**), registration Schnorr verify on the fixed difftest fixture (**35** / **171**, same **`Operational.execVerifyRegistrationProof`** oracle), second FS golden **`vector`** + framework **`bool`** rows (**172** / **173**), empty **`serialize_auditor_*`** vectors (**36** / **37**), and pinned **`serialize_auditor_*`** wires (**114–127**); see `lean/AptosFormal/Refinement/Confidential.lean`.
-- **`move-lean-difftest`**: **`vector`**, **`bcs`**, **`hash`**, **`global_resource_smoke`**, **`confidential_balance`**, **`confidential_elgamal`**, **`confidential_proof`**, **`confidential_asset`** (layer), **`fa_stub`** ([`difftest/src/suites/mod.rs`](difftest/src/suites/mod.rs)); plus **e2e-exported** CA oracle fragments merged for CI (`DIFTEST_MERGE_CA_E2E`).
-- **`AptosFormal.Experimental.ConfidentialAsset.Registration.*`**: **L0** for **`verify_registration_proof`** (crypto story, transcript bytes, axioms/oracles) — **not** bytecode execution in Lean. **`TranscriptAlignment`** pins **`registrationChallengeScalarMove`** on each golden FS `msg` to **`scalarUniformFrom64Bytes`** of the matching **64**-byte SHA2-512 digest (`registrationChallengeScalarMove_golden1_msg_eq_uniform_expectedTaggedHashGolden`, `registrationChallengeScalarMove_golden2_msg_eq_uniform_expectedTaggedHashGolden2`). **`Operational`** includes **`execVerifyRegistrationProof_eq_some_iff_pointEqBool_of_parsed`** (post-parse success ↔ `pointEqBool` on the Schnorr LHS).
-- **VM↔Lean sigma wire lengths (L1-flavored, real `Step`):** indices **128–130** return **`bool(true)`** when the pinned **`deserialize_sigma_*.hex`** byte vectors have lengths **1152** / **1216** / **1792** (`ldConst` + `vecLen` + `eq`) — complements **M11** stubs on **`deserialize_*` `Some`** rows without claiming parser parity.
-- **Wire-level lemmas (L0-flavored, not `eval`):** `AptosFormal.Move.Programs.Confidential` pins VM auditor amount serializer bytes and proves small structural facts (e.g. **`serializeAuditorAmounts_mixed512_orders_distinct`**, **`serializeAuditorAmounts_mixed768_orders_distinct`** — permutations with identical multiset of balances but different vector order are byte-distinct; **`serializeAuditorEksThreeApointWireBytes_length`** / append characterization for **96**-byte triple-**A_POINT** EK wires; **`serializeAuditorEksFourApointWireBytes_length`** for **128**-byte quadruple-**A_POINT** EK wires; **`serializeAuditorEksFiveApointWireBytes_length`** and **`serializeAuditorEksFiveApointWireBytes_eq_deserializeRepeatConcat`** for **160**-byte quintuple-**A_POINT** EK wires vs the same repeat-concat used in sigma layout bytes; **`serializeAuditorEksSixApointWireBytes_length`** / **`serializeAuditorEksSixApointWireBytes_eq_deserializeRepeatConcat`** for **192**-byte sextuple-**A_POINT** EK wires; **`deserializeSigma18Scalars18PointsBytes_five_points_eq_serializeAuditorEksFiveApoint`** / **19** / **transfer** variants — the first five **A_POINT** slots in each checked **`deserialize_sigma_*.hex`** layout match the **160**-byte EK corpus; **`deserializeSigma18Scalars18PointsBytes_six_points_eq_serializeAuditorEksSixApoint`** (and **19** / **transfer** variants) match the first **six** compressed-point slots to the **192**-byte EK corpus), supporting difftest corpora without claiming full `deserialize_*` / `verify_*` in the evaluator.

-### 2.2 Gap
-
-There is **no** end-to-end continuous path yet from **full** **`confidential_asset` / `confidential_proof` / `confidential_balance` / `ristretto255_twisted_elgamal` bytecode** (including globals, FA, and real crypto natives) to **`Move.eval`** + **refinement** + **difftest**. **Partial track B** coverage for the **harness** module exists in **`Refinement.Confidential`** (constant views + sigma length rows); wiring **entrypoints**, **L3** calls, and **L4** state remains open.
-
----
-
-## 3. Guiding principles
-
-1. **Prove the smallest meaningful slice first** (one function, one path, one oracle).
-2. **Separate concerns**: native crypto correctness vs VM stepping vs global storage vs compiler.
-3. **Difftest before hard proofs** for each new bytecode transcription — catches transcription and native wiring bugs early.
-4. **Reuse L0 specs**: refinement theorems should relate `eval` to existing `verifyRegistrationProofProp`-style definitions where possible, rather than duplicating math in prose.
-5. **Document proof obligations**: every `sorry`, axiom, and “trusted disassembly” must be listed for auditors (pattern already in [`lean/README.md`](lean/README.md) and [`REGISTRATION_VERIFY_REVIEW.md`](REGISTRATION_VERIFY_REVIEW.md)).

-**Suggested verification order (bottom-up):**
-
-1. **Crypto primitives + twisted ElGamal** (natives + pure helpers).
-2. **`confidential_balance`** (chunking, homomorphic ops — mostly local).
-3. **`confidential_proof`** (sigma / range / deserialization — heavy natives).
-4. **`confidential_asset`** (composition + **storage**).
-5. **`confidential_gas_e2e_helpers`** (test-only / harness — lower priority unless product depends on it).

-## 5. Workstreams (run in parallel where possible)
-
-### Workstream A — **Native and crypto specs**
-
-**Goal:** For every **Move native** invoked on CA paths, either:
-
-- implement **`List MoveValue → Option (List MoveValue)`** in Lean consistent with `AptosFormal.Std.*` / `AptosFormal.AptosStd.*`, or  
-- document an **`opaque` / axiom** boundary with a **reviewed** contract (weaker).
-
-**Tasks**
-
-- Build a **static call graph** from disassembled CA + dependencies (script or manual table): list each `native fun` and `Call` target.
-- For each native: map to existing Lean (`Std.Hash`, `Std.Bcs`, `AptosStd.Crypto`, …) or add new spec modules.
-- **Bulletproofs / range proof verification**: either full Lean spec (very large) or **oracle** for difftest + abstract interface for proofs (“if native returns `true`, then …”).
-- Align **SHA2-512 (Fiat-Shamir)**, **scalar from bytes**, **decompress**, etc., with goldens already used in registration / Move tests.
-
-**Exit criteria**
-
-- A **checked-in table**: native name → Lean implementation status (`done` / `axiom` / `oracle-only`).
-
-**Partial (tree today):** high-level matrix + status legend for **`aptos_hash` / `ristretto255` / `ristretto255_bulletproofs`** vs CA modules — [`difftest/inventory/confidential_native_matrix.md`](difftest/inventory/confidential_native_matrix.md) (extend with **per-native** rows over time). **Difftest:** VM **`deserialize_*` → `Some`** on fixed sigma layouts (canonical zero scalar + **A_POINT** repeats + empty ZKRP byte vectors); checked-in **hex** (`deserialize_sigma_*.hex`, including transfer extensions **1920** / **2048** / **2176** / **2304** / **2432** / **2560** / **2688** / **2816** / **2944** / **3072** / **3200** / **3328** / **3456** / **3584** / **3712** / **3840** / **3968** / **4096** / **4224** B) + **`move-lean-difftest verify-corpora`** + Lean **`deserializeSigma*Bytes_length`** / prefix lemmas;

-### Workstream B — **Lean bytecode model extensions**
-
-**Goal:** `MoveInstr` / `Step` / `State` support **every instruction** needed by chosen CA bytecode, or a **documented** reduction (e.g. “we only verify inlined core”).
-
-**Tasks**
-
-- For each target function: `movement move compile` + disassemble; diff against supported `MoveInstr` set; extend [`Instr.lean`](lean/AptosFormal/Move/Instr.lean) / [`Step.lean`](lean/AptosFormal/Move/Step.lean) as needed.
-- Revisit **omissions** from [`Move/README.md`](lean/AptosFormal/Move/README.md): **globals**, **variants**, **closures** — decide **per milestone** whether to add them or keep verification **intraprocedural** (function body only with **assumed** initial locals / heap snippet).
-
-**Exit criteria**
-
-- `lake build` green; **smoke** `native_decide` tests run for new instruction paths.
-
----
-
-### Workstream C — **Transcription and `ModuleEnv`**
-
-**Goal:** For each verified function: **`Array MoveInstr`** + **`FuncDesc`** + **constant pool** + **native table** entries match the **compiler output** for this repo revision.
-
-**Tasks**
-
-- Add `Programs/Confidential*.lean` (or similar) mirroring today’s [`Programs/Vector.lean`](lean/AptosFormal/Move/Programs/Vector.lean) pattern: hand-written + **real** `real…Code` where useful.
-- Extend [`Programs.lean`](lean/AptosFormal/Move/Programs.lean) `stdModuleEnv` (or a dedicated **`caModuleEnv`**) with function indices; keep **disassembly provenance** in comments (commit hash, compiler version).
-- Serialization: Move **BCS / vector-of-u8** arguments must match Lean `MoveValue` decoding used by `eval` and difftest.
-
-**Exit criteria**
-
-- For each transcribed function: **bit-identical** or **semantically checked** against Rust VM on a **golden** input (Workstream D).
-
----
-
-### Workstream D — **Differential testing (CA suite)**
-
-**Goal:** New **`move-lean-difftest`** suite (e.g. `confidential` or split by submodule) following [`difftest/README.md`](difftest/README.md).
-
-**Tasks**
-
-- **Rust:** load compiled packages containing CA modules (same layout as today’s vector suite: `InMemoryStorage`, publish modules, invoke script or test entry).
-- **Oracle JSON schema:** extend [`schema.rs`](difftest/src/schema.rs) if needed: function id, serialized args, expected **return values** / **abort** / optional **event** payloads.
-- **Lean:** extend [`DiffTest/Runner.lean`](lean/AptosFormal/DiffTest/Runner.lean) (or parallel) to dispatch CA cases to `eval` / `evalProg` with **`caModuleEnv`**.
-- **`difftest.sh` / CI:** register the new suite in [`suites/mod.rs`](difftest/src/suites/mod.rs).
-
-**Exit criteria**
-
-- One-command run from repo root; CI fails on VM vs Lean mismatch for registered goldens.
-
----
-
-### Workstream E — **Refinement proofs**
-
-**Goal:** **L2/L3** theorems: `eval env f args fuel = …` ↔ your **`Prop`** / functional spec.
-
-**Tasks**
-
-- **Registration (`verify_registration_proof`)**: prove equivalence between **bytecode `eval`** result and **`verifyRegistrationProofProp`** (or `execVerifyRegistrationProof`) under explicit **fuel** and **parsing-success** side conditions — reusing [`Operational.lean`](lean/AptosFormal/Experimental/ConfidentialAsset/Registration/Operational.lean) / [`VerifyMath.lean`](lean/AptosFormal/Experimental/ConfidentialAsset/Registration/VerifyMath.lean).
-- **`confidential_balance`**: lemmas that homomorphic ops match **Twisted ElGamal** specs in Lean (may require **`AptosFormal`** specs for `ristretto255_twisted_elgamal` parallel to Move).
-- **`confidential_proof`**: sigma + range proof **verification** as logical implications from native return + structured inputs.
-- **`confidential_asset`**: only after **L4** or **stubbed** store — prove **local** helpers first.
-
-**Exit criteria**
-
-- No **unintended** `sorry` in shipped modules; `#print axioms` reviewed for each top-level theorem.
-
----
-
-### Workstream F — **Global / resource semantics (L4, optional track)**
-
-**Goal:** Model enough of **storage**, **`signer`**, and **FA** to state theorems about **`public entry fun`** behavior.
-
-**Tasks**
-
-- Extend `MoveValue` / `State` with a **minimal** resource map (type-indexed or monomorphic per milestone).
-- Implement **`borrow_global`**, **`move_to`**, **`exists`**, … as in [`file_format.rs`](https://github.com/aptos-labs/aptos-core/blob/main/third_party/move/move-binary-format/src/file_format.rs) / interpreter — **large**.
-- Integrate **dispatchable FA** behavior used by deposits/withdrawals or **prove** only **internal** `fun` paths that take pre-loaded references.
-
-**Exit criteria**
-
-- At least one **entrypoint**-level theorem **or** a published **negative result** (“we verify `foo_internal` only”) with clear scope.
-
----
-
-## 6. Phased roadmap (milestones)
-
-### Phase 0 — Inventory and proof obligations (2–4 weeks, ongoing)
-
-**Deliverables**
-
-- Call graph: CA modules → natives → stdlib.
-- Table: function → **verification level target** (L0–L5) → owner.
-- List of **goldens** (Move tests) to become difftest oracles.
-
-**Partial (tree today):** registration FS `msg` + SHA2-512 goldens as **hex corpora** with **`cargo run -p move-lean-difftest -- verify-corpora`** (Rust SHA2-512 cross-check vs Lean `TranscriptAlignment`) under [`difftest/corpora/confidential_assets/`](difftest/corpora/confidential_assets/).
-
-**Overlap (difftest track):** the **VM↔Lean inventory** and methodology for CA live under [`difftest/INVENTORY.md`](difftest/INVENTORY.md) and [`difftest/inventory/confidential_assets.md`](difftest/inventory/confidential_assets.md) — extend the formal-plan tables from there or merge in a future edit.
-
-**Dependencies:** none.
-
----
-
-### Phase 1 — CA difftest harness + one golden (4–8 weeks)
-
-**Deliverables**
-
-- New difftest suite: **one** `public` or `public(friend)` function with **minimal** natives (e.g. a **balance** serializer or a **no-op** path).
-- Lean runner + **one** committed or CI-generated oracle.
-
-**Dependencies:** Workstream D; minimal B from **existing** instructions.
-
-**Success:** CI runs VM + Lean on CA package.
-
-**Status (tree today):** Multiple CA-related harness suites and **merged e2e** oracle paths are already wired (see **§2.1**); Phase 1 is **superseded for “existence of a suite”** — remaining Phase 1-style work is **§4.5 checklist depth** (non-witness Lean rows, corpora, `deserialize_*` `Some`, …) on the differential plan.
-
----
-
-### Phase 2 — `ristretto255_twisted_elgamal` + `confidential_balance` (8–16 weeks)
-
-**Deliverables**
-
-- Native/spec coverage for **twisted ElGamal** operations used by balance.
-- Bytecode transcription for **selected** `public fun` in `confidential_balance` (e.g. chunk split, encrypt-with-identity-randomness helpers if bytecode-heavy).
-- Difftest goldens for those functions.
-- **Refinement** for “plaintext chunk vector ↔ ciphertext” for **fixed** small cases, then generalize.
-
-**Dependencies:** A (crypto), B/C, D, E.
-
----
-
-### Phase 3 — `confidential_proof` (16+ weeks, parallelizable by sub-proof)
-
-**Sub-phases**
-
-3a. **Registration bytecode** (`verify_registration_proof`): transcription + natives + difftest + refinement to **existing L0** spec.  
-3b. **Withdraw / normalize / key rotation** proofs: same pattern.  
-3c. **`verify_transfer_proof`**: largest (sigma + Bulletproofs); consider **proof-modular** lemmas (verify sigma subroutine ↔ spec).
-
-**Dependencies:** Phase 2; full A for crypto.
-
----
-
-### Phase 4 — `confidential_asset` (depends on Phase 3 or stubbed proof calls)
-
-**Deliverables**
-
-- Internal `fun` verification where possible **without** L4.
-- **L4** track: entry `confidential_transfer`, `deposit_to`, `withdraw_to`, … with **explicit** store axioms or modeled store.
-
-**Dependencies:** Phase 3 + F if entrypoints required.
-
----
-
-### Phase 5 — Hardening and regression
-
-**Deliverables**
-
-- **Upgrade playbook**: when Move or compiler changes, regenerate disassembly, rerun difftest, re-check `sorry`.
-- Extend **golden consistency** scripts if CA bytes are duplicated in Lean ([`check_golden_consistency.sh`](check_golden_consistency.sh) pattern).
-
----
-
-## 7. Risks and mitigations
-
-| Risk | Mitigation |
-|------|------------|
-| Bulletproofs / range proofs too heavy to spec in Lean | Start **oracle-only** for native return; prove **simpler** lemmas; or bound scope to “native agrees with Rust reference impl” tested by difftest. |
-| Proof effort explodes | **Per-function** milestones; keep **L0** specs as the contract. |
-| Global FA semantics | Default to **L2 internal fun** first; document **L4** as stretch. |
-| Compiler drift | Pin **toolchain + commit** in transcription headers; CI difftest. |
-
----
-
-## 8. “Done” checklist (organization-level)
-
-Use this as a **release gate** for claiming “CA is formally verified” at a given level:
-
-- [ ] **Scope document**: which **functions** and which **level (L0–L5)** per function.
-- [ ] **No undocumented `sorry`** in production Lean modules for claimed theorems.
-- [ ] **`#print axioms`** reviewed and listed (including **`ristretto_subgroup_order_prime`**-style custom axioms).
-- [ ] **Difftest** covers every **transcribed** function on representative inputs (or explains why not).
-- [ ] **REGISTRATION_VERIFY_REVIEW** (or successor) updated to describe **bytecode refinement** if L2+ shipped for registration.
-- [ ] **Move/README.md** updated: which **globals** / **natives** are supported for CA.
-
----
-
-## 9. Summary
-
-Formal verification of **all** confidential assets is a **multi-year**, **multi-workstream** effort if interpreted as **bytecode-level refinement + difftest + eventual storage**. The **feasible** path is:
-
-1. **Keep and extend L0** (already strong for registration math).  
-2. **Add CA difftest** and **grow natives + bytecode** from **twisted ElGamal** and **`confidential_balance`** upward.  
-3. **Prove refinement** incrementally toward **`verify_registration_proof`**, then **other proof verifiers**, then **`confidential_asset`** with an explicit decision on **L4**.
-
-This file is the **living plan**: update phase dates, owners, and checklist as work lands.

-## Summary
-
-| ID | Severity | Topic |
-|----|----------|--------|
-| **M1** | Informational (API / semantics) | `deserialize_*` returns `Some` without validating Bulletproofs wire bytes |
-| **M2** | Documentation (resolved) | `new_scalar_from_sha2_512` (FS challenges) now **`assert!` + `extract`** (`confidential_proof.move`) |
-| **M3** | Informational (precondition) | `#[test_only]` / harness provers use `scalar_invert(..).extract()` — aborts if scalar is non-invertible |
-| **M4** | Informational (harness) | `confidential_gas_e2e_helpers` parses auditor pubkeys with `.extract()` — malformed test inputs abort |
-| **M5** | Informational (abort semantics / UX) | Production **`entry`** paths (e.g. `confidential_transfer`) chain `option::extract()` on balance / auditor / proof deserializers — **malformed client payloads abort** the transaction (safe rejection), not silent state corruption |
-| **M6** | Documentation (resolved) | Doc typo **`suffucient`** on `ensure_sufficient_fa` — fixed to **sufficient** (`confidential_asset.move`) |
-| **M7** | Documentation (resolved) | Awkward phrasing **“decrypt the it”** on `confidential_transfer` — fixed (`confidential_asset.move`) |
-| **M8** | Informational (API naming) | Public function **`new_pending_balance_u64_no_randonmess`** — spelling typo (**randonmess** vs **randomness**); renaming would be a **breaking** API change, so it is documented here rather than “fixed” in-place |
-| **M9** | Informational (API / wire semantics) | **`serialize_auditor_amounts`** concatenates `balance_to_bytes` in **vector order**; permuting the `vector` changes the wire when encodings differ (difftest **120** vs **121** + Lean `serializeAuditorAmounts_mixed512_orders_distinct`; **122** vs **123** + `serializeAuditorAmounts_mixed768_orders_distinct`). Integrations that map auditors to indices must keep the same ordering as Move. |
-| **M10** | Informational (wire ambiguity) | If every serialized ciphertext byte is **zero**, different **`ConfidentialBalance`** sequences can still yield the **same** overall `vector` (e.g. `[pending_zero, actual_zero]` vs `[actual_zero, pending_zero]` are both **768** bytes of zeros on the current VM). Off-chain tools cannot recover per-slot **pending vs actual width** from raw bytes alone without out-of-band typing. |
-| **M11** | Informational (formal / difftest alignment) | VM **`deserialize_*` → `Some`** layout rows vs Lean **length-only** bytecode (**110–113**, same **`Step`** as **128–130**); see **§ M11** below and **`STUB_POLICY.md`**. |
-
-**No production-breaking cryptographic flaw was identified in this pass** from the slices above; the items are documentation of **semantics**, **hardening opportunities**, and **test-only / harness** sharp edges.

-## M1 — `deserialize_*` vs `range_proof_from_bytes` (API semantics)
-
-**Locations**
-
-- `aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move` — `deserialize_withdrawal_proof`, `deserialize_transfer_proof`, `deserialize_normalization_proof`, `deserialize_rotation_proof`.
-- `aptos-move/framework/aptos-stdlib/sources/cryptography/ristretto255_bulletproofs.move` — `range_proof_from_bytes` wraps arbitrary `vector` in `RangeProof` without parsing or rejecting malformed proofs.
-
-**Observation**
-
-`deserialize_*_proof` returns `option::some` whenever the **sigma** sub-deserializer succeeds. The ZK range proof slots are filled via `range_proof_from_bytes`, which **does not** establish cryptographic validity.
-
-**Why this is not automatically a protocol vulnerability**
-
-Soundness for transactions still depends on **`verify_*`** entry paths (and Bulletproofs / Ristretto natives inside them), which perform real verification. `deserialize_*` is better read as **layout / typing** of bytes into structs.
-
-**Risk if misunderstood**
-
-Off-chain tooling or future call sites might treat `Some` as “safe to use in a verify-free path.” That would be incorrect.
-
-**Formal / difftest alignment**
-
-Difftest documents Lean witness limits for VM↔Lean on `deserialize_*`; hex corpora under `difftest/corpora/confidential_assets/deserialize_sigma_*.hex` pin **sigma wire** layouts only. For **`test_deserialize_*_layout_ok_is_some`**, see **M11** (Lean **`ldTrue`** stubs vs VM real parsers). Separate rows **`test_layout_sigma_*_byte_length_is_*`** (**Lean 128–130**) exercise **`vecLen` + `eq`** on the same pinned sigma bytes — length agreement only, not parser replay.

-## M2 — `new_scalar_from_sha2_512` (`option::extract`) — **addressed**
-
-**Location:** `confidential_proof.move` — `new_scalar_from_sha2_512` (Fiat-Shamir challenge derivation).
-
-**Observation (historical)**
-
-Previously both used `option::extract` on `ristretto255::new_scalar_uniform_from_64_bytes` without an immediately adjacent `assert!(option::is_some(&...))`.
-
-**Resolution**
-
-Both paths now **`assert!(option::is_some(&sc_opt), error::invalid_argument(ESIGMA_PROTOCOL_VERIFY_FAILED))`** before **`option::extract`**, so the **64-byte** precondition is explicit if implementations change.
-
-**Analysis (unchanged)**
-
-`ristretto255::new_scalar_uniform_from_64_bytes` returns `some` **iff** the input vector has length **64** (`ristretto255.move`). `ristretto255::new_scalar_from_sha2_512` internally produces a **64-byte** SHA2-512 digest, so `none` remains **unreachable** under current implementations.
-
----
-
-## M3 — `scalar_invert(..).extract()` in `#[test_only]` provers
-
-**Locations (examples)**
-
-- `confidential_proof.move` — `prove_withdrawal`, `prove_transfer`, `prove_normalization`, `prove_rotation`, etc. (all `#[test_only]`).
-
-**Observation**
-
-Prover-side code uses `ristretto255::scalar_invert(dk).extract()` (and similar). `scalar_invert` returns `none` for a **zero** scalar (`ristretto255` tests document this).
-
-**Impact**
-
-Test / harness code **aborts** if a caller passes a zero decryption key (or other non-invertible scalar where applicable). This is **not** a production `public`/`entry` path in the snippets reviewed; it affects **test-only proof generation**.
-
-**Recommendation**
-
-Test harnesses should pass invertible scalars; optional explicit `assert!(option::is_some(&ristretto255::scalar_invert(dk)), …)` improves error messages over a bare `extract` abort.
-
----
-
-## M4 — `confidential_gas_e2e_helpers` auditor pubkey parsing
-
-**Location:** `confidential_gas_e2e_helpers.move` — `pack_confidential_transfer_proof_with_auditors` (and similar loops).
-
-**Observation**
-
-`twisted_elgamal::new_pubkey_from_bytes(auditor_eks[i]).extract()` is used without a per-element `is_some` check.
-
-**Impact**
-
-**Test-only / e2e helper** module: malformed auditor key bytes cause **abort** during packing, not a silent wrong proof. Production entrypoints still run full `verify_transfer_proof` with real crypto.
-
-**Recommendation**
-
-For clearer harness failures, prefer `assert!(option::is_some(&pk), …)` with a descriptive error code before `extract`.
-
----
-
-## M5 — Production `entry` functions and `option::extract`
-
-**Location:** `confidential_asset.move` — e.g. `confidential_transfer` (`new_*_from_bytes`, `deserialize_auditor_*`, `deserialize_transfer_proof`, all `.extract()`).
-
-**Observation**
-
-Several **public entry** functions deserialize caller-supplied bytes and use **`option::extract`** (via `extract()` on `Option`) without an intermediate local and `assert!` with a module-specific error code on every `none` case in the same syntactic pattern (some paths use `assert!` earlier inside helpers).
-
-**Security read**
-
-For malformed proofs / balances / auditor blobs, the typical outcome is **`abort`** (transaction failure), which is **safe** for on-chain state: invalid data does not silently pass verification.
-
-**Operational read**
-
-This is mostly **UX / observability** (clients see a failed transaction; error mapping depends on abort vs structured `error::` paths elsewhere). It is **not** framed here as a soundness vulnerability.
-
----
-
-## M8 — `new_pending_balance_u64_no_randonmess` (spelling)
-
-**Location:** `confidential_balance.move` — `public fun new_pending_balance_u64_no_randonmess`.
-
-**Observation**
-
-The identifier uses **randonmess** instead of **randomness**. This is a **public** API surface; fixing the spelling would require a new function name (and deprecation of the old one) to avoid breaking callers.
-
-**Impact**
-
-None for correctness or security; **documentation / ergonomics** only.
-
----
-
-## M9 — `serialize_auditor_amounts` follows vector order
-
-**Location:** `confidential_asset.move` — `public fun serialize_auditor_amounts`.
-
-**Observation**
-
-The output is a concatenation of per-balance encodings in **`amounts` vector order**. Swapping two non-identical balances (for example zero pending vs **`u64(1)`** no-rand pending) yields a **different** **512**-byte wire. For **768**-byte mixed **actual** + **`u64(1)`** pending rows, reversing vector order changes the byte layout (difftest **122** / **123**); see **M10** for the degenerate all-zero case.
-
-**Impact**
-
-**Not a protocol flaw** — it is the natural encoding. Off-chain code that re-sorts auditor balances or merges lists without preserving on-chain order can produce **unintended** auditor wires relative to what signers / auditors expect. Difftest and Lean (`serializeAuditorAmounts_mixed512_orders_distinct`) document the distinction.
-
----
-
-## M10 — All-zero encodings can collide across different balance shapes
-
-**Location:** `confidential_asset.move` — `serialize_auditor_amounts`; `confidential_balance.move` — `balance_to_bytes`.
-
-**Observation**
-
-`balance_to_bytes` for **pending** zero and **actual** zero (no randomness) produces only **zero** ciphertext bytes on the current VM. Concatenating **256** + **512** in either order therefore yields the same **768**-byte all-zero `vector` for `[pending_zero, actual_zero]` and `[actual_zero, pending_zero]`.
-
-**Impact**
-
-**Not an on-chain ambiguity** for honest modules that deserialize with typed `new_*_from_bytes` length checks. It **is** a footgun for **off-chain** tooling that tries to infer “which slice was pending vs actual” from raw bytes without metadata. Difftest **122**/**123** intentionally use a **non-zero** pending encoding (`u64(1)` no-rand) so VM↔Lean corpora remain byte-order-sensitive.
-
----
-
-## M11 — Lean column for `deserialize_*` layout-`Some` rows (length check, not parser replay)
-
-**Locations:** `AptosFormal.Move.Programs.Confidential` (function indices **110–113**); `AptosFormal.DiffTest.Runner` name mappings; `difftest/src/suites/confidential_proof.rs` harness.
-
-**Observation**
-
-The VM runs real **`confidential_proof::deserialize_*`** on fixed sigma bytes and returns **`option::is_some(&…)`**. The Lean column uses the same bytecode as indices **128–130**: **`ldConst`** (corpus-matching sigma bytes) + **`vecLen`** + **`eq`** against **1152** / **1216** / **1792**, so **`lake exe difftest`** checks a **necessary** layout-length condition (still **not** Bulletproofs slots, Ristretto batch parsing, or friend-module internals in `Move.eval`).
-
-**Related**
-
-Indices **128–130** are the explicitly named harness tests for the same length property; **110–113** align the **`layout_ok_is_some`** oracle rows with that **`Step`** instead of a context-free **`ldTrue`**. Transfer **auditor extension** tiers (**131**/**132** through **151**/**152**) pair **`test_layout_sigma_transfer_*_byte_length_is_*`** with **`test_deserialize_transfer_layout_extended_*_ok_is_some`**: Lean uses **`ldConst` 27**–**37** + **`vecLen`** + **`eq`** on **1920** … **3200** B corpus bytes (one tier per **`ldConst`**); the second index in each pair duplicates the first bytecode (VM-only stronger **`deserialize_transfer`** `Some`).
-
-**Why this is documented**
-
-Lean’s length check can **diverge** from the VM if **`deserialize_*`** later rejects wires that still have the nominal sigma length. **L0** lemmas relate checked-in **`deserialize_sigma_*.hex`** bytes to **`serialize_auditor_eks_*_a_points.hex`** prefixes (**`deserializeSigma*…_five/six_points_eq_serializeAuditorEks*`** in `Confidential.lean`) without claiming full parser parity.
-
----
-
-## Positive checks (no issue filed)
-
-- **`register`** (`confidential_asset.move`) invokes `confidential_proof::verify_registration_proof` **before** `register_internal`, with chain id, addresses, and Fiat–Shamir transcript inputs wired consistently in the reviewed block.
-- **Bulletproofs DST length:** `verify_range_proof` enforces `dst.length() <= 256` (`ristretto255_bulletproofs.move`); CA DST string is shorter — domain separation is enforced where documented.
-
----
-
-## Maintenance
-
-When CA Move sources change behavior relevant to formal work:
-
-1. Update this file if new **verified** observations appear.
-2. Keep **[`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md)** §4.5 / inventory rows aligned with what the formal tree actually claims.
-3. Distinguish **“API hazard / hardening”** from **“soundness break”** — only the latter belongs in urgent security channels without additional review.

-## Quick start
-
-Requires [elan](https://github.com/leanprover/elan) (Lean version manager). The toolchain
-(Lean 4.24.0 + Mathlib 4.24.0) is pinned in `lean/lean-toolchain` and `lean/lakefile.lean`.
-
-```bash
-cd aptos-move/framework/formal/lean
-lake build
-```
-
-See [`lean/README.md`](lean/README.md) for full details on verifying no `sorry` exists, checking
-axioms, running companion Move golden tests, differential tests (`difftest.sh`), and editor setup.
-
-## Directory design
-
-The formal directory lives at `framework/formal/` (not inside `aptos-experimental/`) because
-`AptosFormal.Std.*` modules are **shared across the entire framework**, not specific to any one
-package.
-
-Add future formal trees alongside the same pattern, e.g. `AptosFormal.Framework.*` for
-`aptos-framework` modules, reusing `AptosFormal.Std.*` where Move calls into `aptos_std`.

-# Registration proof verification: what Lean claims vs how to review Move
-
-This note is for **engineers and auditors** working on
-`aptos_experimental::confidential_proof::verify_registration_proof` and the Lean `**AptosFormal`** project under
-`aptos-move/framework/formal/lean/` (Lake package root; shared `**AptosFormal.Std.*`** modules apply across the framework, not only `aptos-experimental`).
-
-**Scope.** The Lean files and this note are aligned with **the Move sources in this branch** (e.g. `aptos-move/framework/aptos-experimental/sources/...`).
-
-**Source of truth (intentional).** The object being reviewed and (eventually) refined against Lean is `**verify_registration_proof` as written in this repository’s Aptos Move**, specifically the implementation under  
-`aptos-move/framework/aptos-experimental/sources/confidential_asset/confidential_proof.move`  
-and the framework modules it calls (`ristretto255`, `twisted_elgamal`, `std::bcs`, etc. **as pinned by this tree**).  
-
-This is **not** a claim about **Move IR**, **bytecode**, a generic “Move semantics,” or another compiler version: any eventual formal link should be stated as refinement to **this source-level behavior** first; IR↔source compiler correctness would be an **additional**, separate obligation if you ever need it.

-Lean **narrows the statement**: “verification succeeds iff these parses succeed and this equation holds.” It does **not** prove that the **framework natives used in this branch** (e.g. SHA2-512 hash, `ristretto255`, `std::bcs`) match the IRTF Ristretto spec or any independent reference, unless you add a large crypto formalization or external proof.
-
-## 2. What “match the verifier’s math” still assumes externally
-
-To identify the Lean `Prop` with successful Move execution you must separately justify:
-
-1. **BCS** — `senderBcs`, `contractBcs`, `tokenBcs` are exactly `std::bcs::to_bytes(&address)` for the same `address` values **this branch’s** Move code uses. In Lean this is modeled by `AptosAddressBcs` + `mkRegistrationInputs` (name = “Aptos-style `address` + BCS”; still **this repo only**).
-2. **Pubkey wire format** — `ekBytes` matches `twisted_elgamal::pubkey_to_bytes(ek)` and `pubkey_to_point` is correct on that encoding.
-3. **Commitment bytes** — `commitmentRBytes` matches `ristretto255::compressed_point_to_bytes(r_compressed)` for the same `R`.
-4. **Response scalar** — `responseBytes` parses like `ristretto255::new_scalar_from_bytes` (canonical encoding, range, etc.).
-5. **Challenge** — `challengeScalarFromMsg` matches `new_scalar_from_sha2_512(FIAT_SHAMIR_REGISTRATION_SIGMA_DST ‖ msg)` including SHA2-512 hashing and reduction mod ℓ.
-6. **Curve API** — `hash_to_point_base`, `point_mul`, `point_add`, `point_decompress`, `point_equals` match the Ristretto implementation Move calls.
-
-The constant `RegistrationVerify.fiatShamirRegistrationDst` is the UTF-8 DST string; the oracle `challengeScalarFromMsg` is responsible for computing `new_scalar_from_sha2_512(DST ‖ msg)` exactly as Move does.
-
-## 3. Pen-and-paper protocol sketch (worked templates you can copy)
-
-This is the **cryptographic story** reviewers use; it is **not** a machine-checked Lean proof.
-
-**Goal (high level).** Show the prover knows a nonzero scalar `**dk`** such that `**ek = dk^{-1} · H`**, where `**H = hash_to_point_base()`** (equivalently `**H = dk · ek**`). Sources: `confidential_proof.move` (`prove_registration` / `verify_registration_proof`) and `ristretto255_twisted_elgamal.move`.
-
-Below, **copy the indented `text` blocks** into your note; they are a first complete draft. Replace bracketed notes if your notation differs.
-
-**Fiat–Shamir (NIZK) [FS87].** The deployed verifier uses `**e := RO(DST ‖ msg)`** instead of a uniformly chosen `e`. Soundness in that setting is argued in the **random oracle model** (§3.5; see [PS00] for the formal treatment of Σ-protocols under Fiat–Shamir).

-
-### 3.1 Setup
-
-```text
-Let (E, +) be the Ristretto255 group of prime order ℓ. Write scalar multiplication as u · P ∈ E for u ∈ ℤ/ℓℤ, P ∈ E.
-Let H ∈ E be the public point from hash_to_point_base().
-Let ek ∈ E be the published registration public key (decompressed from pubkey bytes).
-The prover’s witness is dk ∈ (ℤ/ℓℤ)* satisfying  H = dk · ek   (equivalently ek = dk^{-1} · H).
-The statement is membership of (H, ek) in the language L = { ∃ dk ≠ 0 : H = dk · ek }.
-```
-
----
-
-### 3.2 Interactive protocol (commit → challenge → response)
-
-```text
-Common input: H, ek ∈ E.
-Prover witness: dk with H = dk · ek.
-
-1) Commit:    Prover picks k ← ℤ/ℓℤ uniformly, sends R := k · H ∈ E.
-
-2) Challenge: Verifier picks e ← ℤ/ℓℤ uniformly (interactive case).
-
-3) Response:  Prover sends s := k − e · dk^{-1}   (arithmetic in ℤ/ℓℤ).
-
-4) Verify:    Accept iff s · H + e · ek = R.
-```
-
-**Completeness (honest prover)** — paste and justify each `=`:
-
-```text
-Assume H = dk · ek. Then
-  s·H + e·ek
-    = (k − e·dk^{-1})·H + e·ek
-    = k·H − e·dk^{-1}·(dk·ek) + e·ek
-    = k·H − e·ek + e·ek
-    = k·H = R.
-```
-
-Use scalar laws on the curve: `(ab)·P = a·(b·P)`, `(u+v)·P = u·P + v·P`.
-
-**Move alignment (prover).** `point_mul(h, k)` is `k·H`; `scalar_sub(k, scalar_mul(e, dk_inv))` is `s = k − e·dk^{-1}`.
-
----
-
-### 3.3 Special soundness (two challenges, same `R` → extract `dk`)
-
-**Lemma (template).** Two accepting transcripts `(R, e, s)` and `(R, e′, s′)` with `**e ≠ e′`** yield `**dk`** with `**H = dk · ek`**.
-
-**Proof (copy the algebra):**
-
-```text
-Suppose
-  s·H  + e·ek  = R,
-  s′·H + e′·ek = R.
-Subtract:
-  (s − s′)·H + (e − e′)·ek = 0
-  (s − s′)·H = (e′ − e)·ek.                    (∗)
-Substitute H = dk·ek:
-  (s − s′)·(dk·ek) = (e′ − e)·ek.
-For ek ≠ O in a prime-order group, cancel ek to scalars:
-  (s − s′)·dk = e′ − e,
-  dk = (e′ − e) · (s − s′)^{-1}   (when e ≠ e′ and s ≠ s′).
-```
-
-**One-line reduction:** A cheat who does not know such a `dk` cannot produce two distinct accepting `e` for the same fixed `R` without breaking **discrete logarithm** on `E` (or state your preferred explicit game).
-
----
-
-### 3.4 Honest-verifier zero-knowledge (simulator)
-
-For **interactive** proofs with **uniform** `e`:
-
-```text
-Simulator S(H, ek, e):
-  s ← ℤ/ℓℤ uniform
-  R := s·H + e·ek
-  output (R, e, s).
-
-Then s·H + e·ek = R holds by construction.
-The distribution of (R, e, s) matches the real protocol when the verifier’s e is uniform (standard Schnorr HVZK proof).
-```
-
-For **Fiat–Shamir NIZK**, say explicitly that you use **ROM programming** (different proof template); do not claim interactive HVZK without that caveat.
-
----
-
-### 3.5 Assumptions checklist (tick for your report)
-
-```text
-[ ] (E, +) is the Ristretto255 prime-order group; scalars are in ℤ/ℓℤ.
-[ ] Discrete logarithm (or ECDLP) is hard on E — special soundness reduces forging to breaking it.
-[ ] Interactive: challenge e uniform and independent of prover coins.
-[ ] NIZK: RO model for e = Hash(DST, msg); Fiat–Shamir security for Σ-protocols [FS87, PS00].
-[ ] Wire correctness: decompress/encode for H, ek, R and canonical scalar parsing for s, e.

-
-**One-line soundness story:** *Without `dk`, getting two different valid `e` for the same `R` contradicts special soundness / DLOG; with Fiat–Shamir, the RO makes `e` unpredictable after `R` is fixed.*
-
-## 4. How to review **production Move** (practical)
-
-Lean does not replace this.
-
-1. **Read the code path** — `verify_registration_proof` in `confidential_proof.move` (and callees in `ristretto255` / `twisted_elgamal`).
-2. **Unit tests** — `confidential_proof_tests.move` registration tests: honest proof verifies; wrong `ek`, token, chain, sender, contract fail.
-3. **Cross-check constants** — DST string, order ℓ in Lean `AptosFormal.Std.Crypto.Ristretto255` vs Ristretto / Curve25519 references.
-4. **Cross-check transcript** — `registrationFiatShamirMsg` field order vs `msg.append` order in Move.
-5. **External crypto references** — Ristretto group formulas, DST-prefix domain separation for `new_scalar_from_sha2_512`, and how `std::bcs` encodes `address` **in the framework version pinned by this branch**.
-6. **Optional**: independent implementation (e.g. script) that recomputes `e` and the group check from the same byte inputs for golden test vectors (not required for Lean).
-
-## 5. Where to extend Lean next
-
-- Prove lemmas **assuming** group laws and an injective challenge map (already partly in `AptosFormal.Experimental.ConfidentialAsset.Registration.Formal`).
-- Refine `CryptoOracle` with **axioms** that state algebraic laws (e.g. associativity of `pointAdd`) and relate `challengeScalarFromMsg` to `fiatShamirRegistrationDst` concatenation.
-- A full proof chain to **concrete** framework natives (as compiled from **this** tree) is a **large** separate project; see **§6** for a structured list of what is still missing.
-
----
-
-## 6. Remaining proof obligations (not covered by current Lean)
-
-This section records **everything that is not** machine-checked today, in one place. Completeness of the Schnorr equation and the ideal-oracle bridge are in `AptosFormal.Experimental.ConfidentialAsset.Registration.SchnorrCompleteness`; the items below are **still external** (review, tests, crypto argument, or a future formalization stack).
-
-### 6.1 Move VM semantics
-
-**Goal.** Show that executing `verify_registration_proof` **as defined in this repository’s Move sources** (see the framework table at the top of this doc) **implements** `verifyRegistrationProofProp` (or `verifyRegistrationProofPropMove`) up to the oracle: same **argument order**, same **control flow** on success vs abort. The refinement target is **that source**, not Move IR or bytecode unless you add a compiler-correctness story.
-
-**Current status.** `Operational.lean` defines `execVerifyRegistrationProof` (lines 22–38) which mirrors the Move function's control flow step-by-step. The structural correspondence is:
-
-
-| Move (`confidential_proof.move` lines 214–245)                                     | Lean (`Operational.lean` lines 24–36)                                |
-| ---------------------------------------------------------------------------------- | -------------------------------------------------------------------- |
-| 214–216: `new_compressed_point_from_bytes` / `assert` / `extract` → `r_compressed` | 25: `compressed32?` → `rComm`; 28: `C.pointDecompress rComm` → `rhs` |
-| 219–221: `new_scalar_from_bytes` / `assert` / `extract` → `s`                      | 24: `C.scalarFromBytes responseBytes` → `s`                          |
-| 223–230: Build `msg` + `new_scalar_from_sha2_512` → `e`                            | 29: `C.challengeScalarFromMsg (registrationFiatShamirMsg i)` → `e`   |
-| 233: `hash_to_point_base()` → `h`                                                  | 31: `let H := C.hashToPointBase`                                     |
-| 235: `pubkey_to_point(ek)` → `ek_point`                                            | 26+29: `compressed32?` + `C.pubkeyToPoint ekComm` → `ek`             |
-| 236–239: `point_add(point_mul(h,s), point_mul(ek_point,e))` → `lhs`                | 32: `C.pointAdd (C.pointMul H s) (C.pointMul ek e)`                  |
-| 240: `point_decompress(&r_compressed)` → `rhs`                                     | 28: `C.pointDecompress rComm` → `rhs`                                |
-| 242–245: `assert!(point_equals(&lhs, &rhs))`                                       | 33–36: `if C.pointEqBool lhs rhs then some () else none`             |
-
-
-The theorem `execVerifyRegistrationProof_iff` proves this `Option`-returning function is equivalent to the `Prop`-valued `verifyRegistrationProofProp`.
-
-**Not proved in Lean:**
-
-- Operational semantics of Move (values, references, `assert!` / `abort`, `friend`, gas not-withstanding).
-- That `option::is_some` / `option::extract` on `new_compressed_point_from_bytes`, `new_scalar_from_bytes`, etc., match the `Option` branches in `verifyRegistrationProofProp` (success path vs `False`).
-- That `point_equals` in Move corresponds to `CryptoOracle.pointEq` (or `=` in the idealized bridge).
-
-**Review anchor.** `confidential_proof.move` — `verify_registration_proof` (decompress `R`, parse `s`, build `msg`, `new_scalar_from_sha2_512`, base point `H`, `pubkey_to_point`, `point_add` / `point_mul`, final `assert!`).

-### 6.3 BCS (`address` → transcript bytes)
-
-**Goal.** The bytes fed into `registrationFiatShamirMsg` for `sender`, `contract`, and `token` are **exactly** `std::bcs::to_bytes(&address)` for the same runtime `address` values Move uses, in the **framework version pinned by this branch**.
-
-**Lean model.** `AptosAddress32` + `aptosAddress32Bcs` / `mkRegistrationInputs32`: **32 raw bytes**, no outer length prefix, matching the usual Aptos `address` BCS layout used in this codebase’s Move sources.
-
-**Not proved in Lean:**
-
-- That real `std::bcs::to_bytes(&address)` is always 32 bytes and matches those 32 bytes field-for-field for every address the VM can pass into `verify_registration_proof`.
-- Any change to BCS rules or `address` representation in the framework invalidates a byte-level claim until re-audited.
-
-**Move golden tests (§6.3 evidence).** `formal_goldens_bcs_address.move` (7 passing tests) verifies BCS encoding of `address` values `@0x1`, `@0x2`, `@0x3`, `@0x10`, `@0x20`, `@0x30`, and `@0xFFF…F` as 32 raw bytes with no length prefix, matching the `AptosAddress32` model in Lean.
-
-**Review anchor.** Aptos Move `address` + `std::bcs` spec for the release you ship.

-### 6.3a Bytecode transcription and eval smoke tests (L2)
-
-**What Lean provides today.**
-
-- **Transcribed bytecode** (`AptosFormal.Move.Programs.Registration`): an **83-instruction** `MoveInstr` array faithfully transcribed from the **`movement` v7.4.0** compiler output (`movement move disassemble`, def_idx 39, PC 0–82). Local layout: 7 parameters (chain_id, sender, contract_address, ek, token_address, commitment_bytes, response_bytes) + 12 temporaries (19 locals total). The transcription uses reference-semantic instructions (`immBorrowLoc`, `mutBorrowLoc`) matching the compiler output exactly.
-
-- **Oracle-parameterized natives** (`AptosFormal.Move.Native.Registration`): `RegistrationNativeOracle` bundles Ristretto point operations, scalar parsing, pubkey wire conversions, and twisted ElGamal helpers. Crypto-ops use `FuncBody.nativeRef` (receiving `ContainerStore` + `List MoveValue` and returning `Option (List MoveValue × ContainerStore)`) with a `derefImm` helper that transparently handles both immutable references (`.immRef id` → container store lookup) and direct values (pass-through). Non-oracle natives (SHA2-512 hash, BCS, Option is_some/extract, vector append/singleton) use `FuncBody.native` and are **executable** in Lean (no oracle).
-
-- **Module environment** (`registrationModuleEnv`): 18-slot function table (indices 0–9 oracle `nativeRef`, 10–16 executable `native`, 17 bytecode verifier). Constant pool entry 0 is the `FIAT_SHAMIR_REGISTRATION_SIGMA_DST` bytes.
-
-- **Eval smoke tests** (`…Registration.BytecodeSmoke`): `native_decide` proofs that `eval` on golden inputs (with **reference args**: `.immRef 0` for ek and a pre-populated `MachineState`) produces `returned []` (valid proof) and `aborted 65537` (invalid proof). These run the full evaluator loop (200 fuel steps) through all 83 instructions with container-store threading.
-
-- **MachineState projection** (`ExecResult.dropMs` in `EvalEquiv.lean`): The 83-instruction bytecode populates the `ContainerStore` via `immBorrowLoc`/`mutBorrowLoc`/`nativeRef` calls, so `eval` returns `.returned [] ms` where `ms` has a non-empty container store. The functional simulation returns `.returned [] MachineState.empty`. `ExecResult.dropMs` projects away the `MachineState` from `.returned` outcomes (replacing with `MachineState.empty`), enabling comparison of observable results (return values / abort codes) while abstracting over the differing container stores. Includes `@[simp]` lemmas and bidirectional `_iff` lemmas for all constructors.
-
-- **Refinement theorems** (`…Registration.Refinement`):
-  - `func_success_implies_exec_some` — **proven (no sorry)**: if the bytecode-level functional sim returns successfully, the spec-level runner also returns `some ()`. Uses `OracleCoherence` (both forward and reverse properties), `func_success_extracts` (structural decomposition of the 15-layer nested match), and `buildFSMessageMv_list_gen` (message coherence through `ByteArray.toList_append`).
-  - `func_abort_implies_exec_none` — **proven (no sorry)**: if the functional sim aborts, the spec-level runner returns `none`. Uses `func_abort_classification` (3-way abort decomposition) + failure-direction `OracleCoherence` properties (`compressedFromBytes_false_rev`, `scalarFromBytes_false_rev`).
-  - `eval_success_implies_prop` — **composition proven (no sorry in proof body)**: composes `eval_eq_func` (via `.dropMs`) + `func_success_implies_exec_some` + `execVerifyRegistrationProof_iff`. Accepts any returned `MachineState` `ms` (not just `MachineState.empty`), since the real bytecode leaves references in the container store. Depends on `eval_eq_func` (sorry in `eval_eq_func_100`) for the L2≡L1.5 step.
-  - `eval_abort_implies_not_prop` — **composition proven (no sorry in proof body)**: composes `eval_eq_func` (via `.dropMs`) + `func_abort_implies_exec_none` + `execVerifyRegistrationProof_iff`. The `.aborted` constructor doesn't carry `MachineState`, so `.dropMs` is trivial. Depends on `eval_eq_func` (sorry in `eval_eq_func_100`).
-  - `eval_eq_func` — **largely proven**: lifts `eval_eq_func_100` (at fuel 200) to arbitrary `fuel ≥ 200` via `eval_fuel_ge_dropMs`. Uses `by_cases` on whether `eval` at fuel 200 is `.error`. **One residual sorry** for error-fuel-monotonicity: when the oracle returns garbage (both sides are `.error`), proving `eval fuel = .error` from `eval 200 = .error` requires bounded-execution-length formalization. This case is vacuous for all callers (which assume `eval` returns `.returned` or `.aborted`).
-  - `eval_eq_func_100` — **sorry** (in `EvalEquiv.lean`): states that `(eval ... 200 MachineState.empty).dropMs = verifyRegistrationBytecodeResult ...` for all abstract oracles, using **value args** (struct for ek, not `.immRef`). The `nativeRef` wrappers handle non-ref values via `derefImm` (pass-through). Proving this requires symbolic bytecode stepping through 83 instructions with container-store threading. Concrete instances verified by `native_decide` in `BytecodeDifftestEval.lean`.
-
-- **Functional simulation** (`…Registration.FunctionalSim`): `verifyRegistrationBytecodeResult` — a readable Lean function on `MoveValue`s that mirrors the bytecode's control flow, returning `MachineState.empty` in all cases. Serves as the L1.5 intermediary: `eval ≡ L1.5` is verified by `native_decide` on concrete oracles (via `.dropMs`); `L1.5 ≡ L1` is algebraic under oracle coherence. Includes `func_trichotomy`, `buildFSMessageMv` (Fiat-Shamir message construction), `buildFSMessageMv_list` and `buildFSMessageMv_list_gen` (message correctness proven, no sorry). `ByteArray.toList_append` is axiomatized as a library-level obligation (verified concretely by `native_decide` for every tested ByteArray pair; orthogonal to the cryptographic verification).
-
-- **Concrete refinement chain** (`…Registration.BytecodeDifftestEval` + `…Registration.BytecodeDifftestBridge`): **Four independent oracle traces** with `native_decide` proofs in two categories:
-
-  *Smoke tests* (reference args + populated `MachineState`, testing `eval` directly):
-  - Trace 1 (dk=42/k=9999, chainId=9, @0x1/@0x2/@0x3): eval success (1 proof).
-  - Trace 2 (chainId=42, @0x10/@0x20/@0x30, basepoint ek/R): eval success + eval abort (bad commitment) (2 proofs).
-  - Trace 3 (scalar-stage abort): eval abort with scalar `optionIsSome` false (1 proof).
-  - Trace 4 (point-equality-false abort): eval abort with `pointEquals` false (1 proof).
-
-  *Func≡eval tests* (value args + `MachineState.empty` + `.dropMs`, testing `eval` vs `verifyRegistrationBytecodeResult`):
-  - Trace 1: `func_eq_eval_difftest_val` (func=eval via `.dropMs`) + `func_difftest_returns` (func returns `[]`) (2 proofs).
-  - Trace 2: `func_eq_eval_trace2_val` (func=eval) + `func_trace2_returns` (func returns `[]`) + `func_trace2_aborts` (func aborts on bad commitment) + `func_trace2_scalar_aborts` (func aborts on bad scalar) + `func_trace2_pointeq_false_aborts` (func aborts on point inequality) (5 proofs).
-
-  - `BytecodeDifftestBridge` composes trace 1 into `difftest_L2_implies_L0` (no sorry), proving the full L2 → L0 chain.
-
-- **Difftest honest L1 column** (`caRegistrationBytecodeEvalNative` at index 194 in `confidentialModuleEnv`): wraps `eval` + `registrationModuleEnv` with the concrete difftest oracle, mapped in `RunnerFuncMappingAux` as `test_registration_bytecode_eval_roundtrip`. This enables cross-checking the Lean bytecode evaluator against the Rust VM in the difftest matrix.
-
-- **L4 entry-point stub** (`…Registration.RegisterEntryStub`): `registerEntrySpec` models the `register` entry function as parse-ek + verify-proof + store. Two proven theorems: `register_success_implies_verify_success` (success implies the embedded proof verification returned) and `register_success_stores_ek` (stored ek matches input bytes). No `sorry`.
-
-**What remains.**
-
-1. **`eval_eq_func_100` (L2 ≡ L1.5, abstract) — sorry.** The theorem states `(eval ... 200 MachineState.empty).dropMs = verifyRegistrationBytecodeResult ...` for all abstract oracles. Proving this requires symbolic stepping through 83 instructions with container-store threading (each `immBorrowLoc`/`mutBorrowLoc` allocates in the `ContainerStore`; each `nativeRef` call reads/writes). Concrete instances are verified by `native_decide` for 4 independent oracle traces. The `EvalEquiv.lean` file contains `@[simp]` fusion lemmas (`match_single?`, `bind_single?`, `match_match_some_single_none`, `runStep_handleNativeResult_ret1/ret0`) and `runStep` machinery designed for the symbolic proof, but the full `simp` + `split` proof is not yet completed due to term-size from container-store threading.
-2. **Error-fuel-monotonicity sorry in `eval_eq_func`.** When `eval` at fuel 200 returns `.error` (oracle returns garbage), lifting to arbitrary `fuel ≥ 200` requires proving `eval fuel = .error` for the `.error` case. This sorry is **vacuous for all callers** (`eval_success_implies_prop`, `eval_abort_implies_not_prop`) since they assume `eval` returns `.returned` or `.aborted`.
-3. **`ByteArray.toList_append`/`ByteArray.toList_mk_singleton` axioms.** Library-level obligations for `ByteArray.toList` distributivity. Both are concretely verified by `native_decide` for every tested pair. A proper proof requires a loop invariant on the irreducible `ByteArray.toList.loop`. This is orthogonal to the cryptographic claims.
-

-
-### 6.3d Bytecode disassembly cross-check (compiler output vs Lean transcription)
-
-**Goal.** Verify that the hand-transcribed `MoveInstr` array in `AptosFormal.Move.Programs.Registration` faithfully represents the actual bytecode produced by the production compiler for `verify_registration_proof`.
-
-**Method.** Compiled `aptos-experimental` with `movement` v7.4.0 (`movement move compile --package-dir aptos-move/framework/aptos-experimental --named-addresses "aptos_experimental=0x1"`), then disassembled the output (`movement move disassemble --bytecode-path .../confidential_proof.mv`). The disassembly lives at `aptos-move/framework/aptos-experimental/build/AptosExperimental/bytecode_modules/confidential_proof.mv.asm`, lines 4811–4914, function definition index 39.
-
-#### Current status: faithful 83-instruction transcription
-
-The Lean transcription now contains **83 instructions** (PC 0–82) with **19 locals** (7 params + 12 temporaries), matching the compiler output **instruction-for-instruction** including all reference-semantic instructions (`immBorrowLoc`, `mutBorrowLoc`), abort blocks, and temporary variables. The `registrationModuleEnv` uses `FuncBody.nativeRef` for crypto operations that receive references in the real bytecode, and `FuncBody.native` for pure operations (BCS, vector, Option, SHA2-512).
-
-#### Previous state (archived divergence analysis)
-
-The original §6.3d analysis documented 10 divergence types (D1–D10) between a previous 67-instruction value-semantics abstraction and the 83-instruction compiler output. That analysis remains valid as historical documentation of *why* the value-semantics abstraction was behavior-preserving, but is no longer the current Lean code.
-
-The retranscription to 83 instructions was motivated by the need to:
-1. Eliminate the manual behavior-preservation argument (D1–D10) by matching the compiler output exactly.
-2. Enable `native_decide` proofs that run `eval` on the real bytecode with reference arguments (verified in `BytecodeSmoke.lean`).
-3. Support the `nativeRef` native function calling convention (receiving `ContainerStore` for reference dereferencing).
-
-#### MachineState abstraction via `ExecResult.dropMs`
-
-The 83-instruction bytecode, due to `immBorrowLoc`/`mutBorrowLoc`/`nativeRef` calls, populates the `ContainerStore` during execution. After `eval` completes, the returned `MachineState` contains allocated reference entries that are semantically irrelevant (all references are local to the function and never escape). The functional simulation (`verifyRegistrationBytecodeResult`) returns `MachineState.empty`.
-
-`ExecResult.dropMs` (defined in `EvalEquiv.lean`) bridges this gap by projecting `.returned vs ms` to `.returned vs MachineState.empty`, enabling comparison of observable outcomes:
-- **Success**: same return values (`[]` for void return)
-- **Abort**: same abort code (`65537`)
-- **Error**: same `.error` (oracle returns garbage)
-
-This is a weaker claim than full `MachineState` equality but is **sufficient for the refinement chain**: the L1.5→L1→L0 layers only inspect return values and abort codes, never the final container store.
-
-#### Constant pool
-
-The compiler's constant pool index 5 contains the BCS-serialized DST vector: `[38, 77, 111, ...]` (38 = ULEB128 length prefix, then 38 bytes of `"MovementConfidentialAsset/Registration"`). The Lean model's constant pool index 0 stores the deserialized `MoveValue.vector .u8 [77, 111, ...]`. The VM deserializes constants at load time, so these are equivalent: `LdConst` pushes the same 38-byte vector onto the stack in both cases.
-
-#### Summary
-
-The Lean bytecode array is a **faithful 83-instruction transcription** of the `movement` v7.4 compiler output for `verify_registration_proof`, including all reference-semantic instructions. The `ExecResult.dropMs` projection abstracts over the `MachineState` difference (populated `ContainerStore` vs empty) that arises from reference operations, enabling comparison of observable outcomes (return values / abort codes). This observable-outcome equivalence is:
-- **Verified by `native_decide`** for 4 independent concrete oracle traces (7 func≡eval proofs in `BytecodeDifftestEval.lean`).
-- **Stated for all abstract oracles** in `eval_eq_func_100` (sorry — requires symbolic stepping through 83 instructions with container-store threading).
-- **Sufficient for the full refinement chain** (L2→L0), since downstream layers only inspect return values and abort codes.

-### 6.4 Cryptographic security (soundness / knowledge soundness)
-
-**What Lean proves today.**
-
-- **Completeness** of the Schnorr check for an honest prover (`registrationSchnorr_completeness`, `registrationVerifySpec_completeness` in `…Registration.SchnorrCompleteness`).
-- **Special soundness** (`registrationSchnorr_witness_extraction` in `…Registration.CryptoSecurity`): two accepting transcripts `(R, e₁, s₁)` and `(R, e₂, s₂)` with `e₁ ≠ e₂` yield an explicit witness `dk = (s₁ − s₂)⁻¹ · (e₂ − e₁)` with `H = dk · ek`. The proof uses `Field RistrettoScalar` (via the `Fact (Nat.Prime ℓ)` instance) for scalar inversion.
-- **HVZK simulator** (`registrationSchnorr_simulate` / `registrationSchnorr_simulate_accepts`): given `(H, ek, e, s)`, the simulator produces `R := s·H + e·ek` which is always an accepting transcript.
-- **Fiat–Shamir symbolic model** (`…Registration.FiatShamirSymbolic`):
-  - **Forking reduction** (`fiatShamir_forking_extraction`): two valid NIZK proofs in "oracle worlds" with different challenges for the same FS message yield witness extraction — the algebraic core of the ROM forking lemma [PS00].
-  - **Explicit extraction formula** (`fiatShamir_forking_explicit`): `dk = (s₁ − s₂)⁻¹ · (e₂ − e₁)`.
-  - **Challenge binding** (`fiatShamir_challenge_binding`): for a fixed hash function, two proofs with the same commitment share the same challenge, so a single-oracle adversary cannot fork.
-  - **NIZK completeness** (`fiatShamir_completeness`): the honest Fiat–Shamir prover always passes.
-  - **NIZK zero-knowledge** (`fiatShamir_nizk_simulate_accepts`): a simulator with oracle-programming ability produces valid proofs without the witness.
-
-**Not proved in Lean (pen-and-paper / ROM in §3):**
-
-- **Forking probability** — the probability that an adversary triggers the two-oracle-world scenario is shown to be non-negligible in [PS00] via a rewinding argument; this probabilistic argument requires a probability monad or game-based framework.
-- **Hardness** — discrete logarithm (or equivalent) on the Ristretto255 group.
-
-Lean does **not** formalize a random oracle, a computational game, or a reduction to DLOG.
-
----
-
-### 6.5 Primality of ℓ (subgroup order)
-
-**Current status.** `ristretto_subgroup_order_prime : Nat.Prime ristrettoSubgroupOrder` is an `**axiom`** in `AptosFormal.Std.Crypto.Ristretto255` (spec constant from Ristretto / Curve25519 literature), not a **formal primality certificate** inside Lean. A `Fact (Nat.Prime ristrettoSubgroupOrder)` instance is derived from the axiom, making `Field RistrettoScalar` available everywhere (used by the special soundness proof in `CryptoSecurity.lean`).
-
-**To remove the axiom.** Supply a **Pratt primality certificate** for `ristrettoSubgroupOrder` and verify it in Lean. This requires:
-
-1. The complete factorization of `ℓ − 1` (obtainable from a computer algebra system like SageMath or PARI/GP).
-2. A primitive root `g` modulo `ℓ`.
-3. Recursive Pratt certificates for each prime factor of `ℓ − 1`.
-
-Trial division (`native_decide` on `Nat.Prime`) is infeasible for a 252-bit prime (≈ 2^126 trial divisions).
-
-**Review anchor.** Standard curve parameters [HDEVALENCE, Ber06] vs the numeric literal in `AptosFormal.Std.Crypto.Ristretto255`.

-# Difftest inventory & methodology (Phase 0)
-
-This document is the **hub** for planning and extending **Move VM ↔ Lean** differential tests (`move-lean-difftest` + `lake exe difftest`). It applies to **any** Move package you later wire into the harness (stdlib wrappers, framework modules, confidential assets, …).
-
-## 1. Source of truth — tests are allowed to fail
-
-- The **JSON oracle** is produced by running the **real Move VM** (Rust) on concrete inputs. Those outputs are treated as **ground truth for that run**.
-- The **Lean** side **re-computes** the same case using `AptosFormal.Move` and **compares** to the oracle.
-- **If Move code is wrong** but Lean matches a *correct* spec, the VM oracle will still record what Move *actually* did — a **later** Lean change to match buggy Move would show as “passing” while being wrong. The intended discipline is:
-  - **Independent** expectations for high-value cases (e.g. golden vectors from crypto reviews, or second tooling), **or**
-  - **Regression**: when you **intentionally fix** Move, the oracle **must be regenerated**; Lean should then match the **new** VM behavior — a **failure** before regen catches drift.
-- **If Lean is wrong** (transcription, missing instruction, wrong native), comparison **fails** — that is the point of difftest.
-
-Neither implementation is assumed correct **by construction**; agreement is **evidence** on the oracle set only.
-
-## 2. Suite registry (generic harness)
-
-- **Rust:** one implementation of `DiffTestSuite` per logical area; register in [`src/suites/mod.rs`](src/suites/mod.rs) (`all_suites` + `suites_filtered` match arms — **keep match arms in sync** with `all_suites()`).
-- **List ids:** `cargo run -p move-lean-difftest -- --list-suites` or `./aptos-move/framework/formal/difftest.sh --list-suites`.
-- **Lean:** extend `AptosFormal.DiffTest.Runner` (`funcNameToMapping` / case dispatch) and `Move` `ModuleEnv` / natives for each **new** function you add to an oracle.
-
-See [`README.md`](README.md) § *Adding coverage* for the file-level checklist.
-
-## 3. Inventory artifacts (Phase 0 deliverables)
-
-| Document | Purpose |
-| -------- | ------- |
-| [`STUB_POLICY.md`](STUB_POLICY.md) | Lean column: bytecode vs natives vs abstract globals (CA plan §3). |
-| [`inventory/README.md`](inventory/README.md) | Index of per-package inventories. |
-| [`inventory/confidential_assets.md`](inventory/confidential_assets.md) | **Confidential assets (experimental)** — public API surface, difftest mode per symbol, native/transitive deps. Independent vectors (checklist §4.3 iii): [`corpora/confidential_assets/README.md`](corpora/confidential_assets/README.md). |
-| [`inventory/confidential_native_matrix.md`](inventory/confidential_native_matrix.md) | **CA native / crypto matrix** — `aptos_std` Ristretto/BP/hash vs Lean status (FV plan Workstream A). |
-| [`inventory/move_framework_template.md`](inventory/move_framework_template.md) | Blank template for **other** Move framework packages. |
-
-## 4. Difftest modes (per function / case)
-
-Use these labels in inventory tables:
-
-| Mode | Meaning |
-| ---- | ------- |
-| **VM↔Lean** | Full differential: oracle from VM, Lean `eval` must match. |
-| **VM-only** | Oracle recorded from VM; Lean column **skipped** until model exists (document reason). |
-| **Blocked** | Cannot run in harness yet (missing compiler support, storage, …). |
-
-## 5. When you add a new suite (checklist)
-
-1. Add `src/suites/.rs` implementing `DiffTestSuite`.
-2. Register in `all_suites()` **and** the `suites_filtered` match in [`mod.rs`](src/suites/mod.rs).
-3. Run `cargo run -p move-lean-difftest -- --list-suites` and confirm the new id appears.
-4. Extend Lean `DiffTest` runner + `ModuleEnv` for each `TestCase` you emit.
-5. Add an **`inventory/.md`** row or standalone doc for long-term tracking.
-
-## 6. Related plans
-
-- Confidential assets **difftest-only** roadmap: [`../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md) (Phase 0 marked complete there with pointer here).
-- Full formal verification (refinement + globals): [`../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md).

-# JSON oracle changelog (`move-lean-difftest` → `lake exe difftest`)
-
-The Lean runner (`AptosFormal.DiffTest.JsonParser`) and the Rust harness (`schema.rs`) must stay in lockstep. When the JSON shape changes incompatibly:
-
-1. Bump `CURRENT_SCHEMA_VERSION` in `difftest/src/schema.rs`.
-2. Update the Lean parser and any `TestSuite` / `TestCase` structures as needed.
-3. Add a row below and regenerate committed or ignored oracle files.
-
-## Versions
-
-| Version | Date | Summary |
-|--------:|------|---------|
-| **1** | 2026-04-10 | Introduced `schema_version` (number) at suite root. Fields unchanged from prior informal format: `generator`, `module`, `test_cases` with `function`, `args`, `result` (`status` + `values` or `abort_code`). Older files without `schema_version` are accepted by Lean as `schemaVersion := none`. |
-
-**Tooling (not a schema bump):** `cargo run -p move-lean-difftest -- verify-corpora` — authoritative Rust **hex corpus** checks for confidential-assets goldens (registration DST, FS `msg` lengths, SHA2-512 digest chain, Bulletproofs DST + SHA3-512 digest, `deserialize_sigma_*.hex`, `serialize_auditor_*.hex`). CI and **`difftest.sh` \[0\]** use this command.
-
-**Compatible extension (still schema version 1):** optional per-case boolean **`skip_lean`**. When `true`, the Lean runner skips that row (VM-only oracle); omitted or `false` keeps VM↔Lean checks. Rust omits the field when `false` on serialize.
-
-**`OracleFragment`:** JSON object with only **`test_cases`** (same `TestCase` shape as in a full `TestSuite`). Accepted by `move-lean-difftest merge` as an append file; produced by `e2e-move-tests` when **`CONFIDENTIAL_ASSET_E2E_ORACLE_OUT`** is set (see formal difftest README).

-## Policy
-
-- **Compatible** additions (optional fields, new `type` variants for typed values with backward parsing) do not require a version bump if Lean and Rust both accept old oracles.
-- **Incompatible** changes (renames, removed fields, changed `result` encoding) require a bump and a changelog entry.

-# Move ↔ Lean differential tests (`move-lean-difftest`)
-
-These tests compare the **real Move VM** (Rust) against the **Lean bytecode evaluator** on the same inputs and expected outputs. The Rust binary writes a **JSON oracle**; the Lean executable reads it and reports pass/fail.
-
-This is **runtime empirical checking**, not a formal proof. The oracle is **VM output** — if Move and Lean disagree, **something is wrong** (Move bug, Lean model bug, or stale oracle); do not assume confidential assets (or any module) is correct **a priori**.
-
-**Phase 0 inventory (planning, any future suite):** [`INVENTORY.md`](INVENTORY.md) and [`inventory/`](inventory/).
-
-## Git and CI
-
-**Registration + CA corpora (§4.5 / independent vectors):** [`corpora/confidential_assets/`](corpora/confidential_assets/) holds hex goldens for registration FS `msg`, SHA2-512 digest, Bulletproofs `DST` + SHA3-512 digest, **`deserialize_sigma_*.hex`** sigma wire layouts, and **`serialize_auditor_*.hex`** serializer pins. **Authoritative semantics** for CA behavior remain: (1) the **Move VM** when generating `difftest_oracle*.json`, and (2) **`lake exe difftest`** comparing that JSON to Lean `eval`. The corpus step is an extra **static** gate: length checks, recomputing SHA2-512/SHA3-512 chains, and byte-for-byte comparisons against small fixed constants. That gate is implemented only in **Rust** (`cargo run -p move-lean-difftest -- verify-corpora`, also `#[test]` in `corpus_verify.rs`). **`../difftest.sh`** runs `verify-corpora` as step **\[0\]**; **`.github/workflows/formal-difftest.yaml`** does the same after the pinned toolchain. Move semantics notes: [`../CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md`](../CONFIDENTIAL_ASSETS_MOVE_AUDIT_NOTES.md).
-
-**`difftest_oracle*.json` is gitignored** — it is generated output from the real VM, not source. Regenerate with `cargo run -p move-lean-difftest` (or `../difftest.sh`) before running `lake exe difftest`, or rely on a CI job that runs the harness then Lean in one pipeline.
-
-If you prefer **committed goldens** (offline Lean-only runs, PR diffs when VM output changes), remove the `difftest_oracle*.json` line from `difftest/.gitignore` and check the files in — trade-off is noisier PRs and risk of stale oracles.
-
-## Naming (not vector-specific)
-
-- **`difftest_oracle.json`** — default file holding VM ground truth for **all** registered suites (`vector`, `bcs`, `hash`, `global_resource_smoke`, `confidential_balance`, `confidential_elgamal`, `confidential_proof`, `confidential_asset`, `fa_stub`, or **`--suite confidential`** for the four confidential-related suites only). The old name `test_vectors.json` suggested everything was about `vector.move`; the new name matches “oracle for differential testing.”
-- **`schema_version`** — integer at the JSON root (`CURRENT_SCHEMA_VERSION` in Rust). Document incompatible bumps in [`ORACLE_CHANGELOG.md`](ORACLE_CHANGELOG.md).
-- **`skip_lean`** — optional per test case (`false` or absent = run Lean). Use `true` for VM-only rows when merging transactional e2e output into the same oracle file as VM↔Lean suites (Lean reports **SKIP** for those cases).
-
-**One JSON file (VM↔Lean + VM-only):** after you have a VM oracle from this crate and a separate fragment (full `TestSuite` or `{ "test_cases": [...] }`, e.g. exported from `e2e-move-tests`), merge them so Lean runs once:
-
-```bash
-# from repo root (input paths resolve via the difftest crate manifest, then cwd;
-# relative `-o` resolves against cwd when the parent directory exists, else the crate dir)
-cargo run -p move-lean-difftest -- merge -o difftest_merged.json \
-  aptos-move/framework/formal/difftest/difftest_oracle.json \
-  path/to/e2e_fragment.json
-cd aptos-move/framework/formal/lean && lake exe difftest ../difftest/difftest_merged.json
-```
-
-`merge` **preserves** each appended file’s `skip_lean` flags by default (use **`--force-skip-lean`** only if you want every appended row forced to VM-only). See **`cargo run -p move-lean-difftest -- merge --help`**.
-
-**CA transactional e2e → `OracleFragment`:** `e2e-move-tests` depends on this crate’s library types. The test **`export_confidential_asset_e2e_oracle_fragment`** runs all confidential-asset VM scenarios once and writes JSON when **`CONFIDENTIAL_ASSET_E2E_ORACLE_OUT`** is set to a file path. **Relative paths** are interpreted from the **workspace repo root** (two levels above `e2e-move-tests`’s `Cargo.toml`), so the recipe below works without an absolute path.
-
-```bash
-export CONFIDENTIAL_ASSET_E2E_ORACLE_OUT=aptos-move/framework/formal/difftest/difftest_ca_e2e_fragment.json
-RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests export_confidential_asset_e2e_oracle_fragment -- --test-threads=1
-```
-
-Then **`merge`** that file into the harness oracle and run **`lake exe difftest`** on the merged file (see **`.github/workflows/formal-difftest.yaml`** for the CI recipe).
-
-### CI parity: harness + CA e2e → merged Lean run
-
-**On PRs**, [`.github/workflows/formal-difftest.yaml`](../../../.github/workflows/formal-difftest.yaml) runs, in order: **`verify-corpora`** → VM harness (`cargo run -p move-lean-difftest -- --quiet`) → **`export_confidential_asset_e2e_oracle_fragment`** (writes `difftest_ca_e2e_fragment.json`) → **`merge`** into **`difftest_ci_merged.json`** → **`lake exe difftest`** on that merged file. You do **not** need to commit those JSON files: they are listed in [`difftest/.gitignore`](.gitignore); CI regenerates them whenever the workflow runs.
-
-**Locally** (same shape as CI, including export + merge — **slow** because the export test runs every CA e2e oracle scenario in `all_fragment_cases()`):
-
-```bash
-# From repo root
-DIFTEST_MERGE_CA_E2E=1 ./aptos-move/framework/formal/difftest.sh
-```
-
-Without `DIFTEST_MERGE_CA_E2E=1`, the script still runs **`verify-corpora`**, the VM harness, and Lean on **`difftest_oracle.json`** only (no e2e fragment, no merged file).
-
-### Checklist: adding a new CA transactional e2e oracle row
-
-Keep CI green when extending the VM↔Lean fragment:
-
-1. Add the scenario in [`../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e_oracle_impl.rs) and append it from **`all_fragment_cases()`**.
-2. Add a **`#[test]`** wrapper in [`../../e2e-move-tests/src/tests/confidential_asset_e2e.rs`](../../e2e-move-tests/src/tests/confidential_asset_e2e.rs) so `cargo test` exercises the harness path.
-3. Map the full oracle id in [`../lean/AptosFormal/DiffTest/RunnerFuncMappingAux.lean`](../lean/AptosFormal/DiffTest/RunnerFuncMappingAux.lean) (`funcIdx` + env flags).
-4. Record the extension in [`ORACLE_CHANGELOG.md`](ORACLE_CHANGELOG.md) and a row in [`inventory/confidential_assets.md`](inventory/confidential_assets.md).
-
-Then run **`DIFTEST_MERGE_CA_E2E=1 ./aptos-move/framework/formal/difftest.sh`** before landing if you changed Lean or need to reproduce CI locally.
-
-- **`difftest.sh`** — one-shot script at `formal/difftest.sh` (next to `lean/` and `difftest/`). It is **not** only for vector tests.
-
-The Move module **`0x1::difftest_vector`** is only the **vector** suite’s wrapper; BCS and hash use **`difftest_bcs`** and **`difftest_hash`**. Confidential-asset smoke modules: **`0x1::difftest_confidential_balance`**, **`difftest_confidential_proof`**, **`difftest_confidential_asset_layer`**.
-
-**`confidential_asset` and globals:** the Lean `Move.*` model has a **minimal global map**
-(`MachineState` + `GlobalResourceKey`; see [`STUB_POLICY.md`](STUB_POLICY.md) and
-[`../lean/AptosFormal/Move/README.md`](../lean/AptosFormal/Move/README.md)). It is **not**
-full Aptos `borrow_global` / FA / signer wiring. The **`confidential_asset`** suite still
-follows **Option B** from [`../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md): only **functions that need no globals**
-stay in the VM↔Lean oracle until bytecode + keys + policy are extended; FA-heavy
-entrypoints stay inventory-**Blocked** or move to Option C (VM-only column).
-
-**Transactional CA + real `verify_*` / `register` (VM only, not this JSON pipeline):** the repo already runs **`MoveHarness`** scenarios in **`e2e-move-tests`** (test-mode bytecode inject, FA + store, full proof paths). See plan [**§7.0**](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md). From repo root:
-
-```bash
-RUST_MIN_STACK=8388608 cargo test -p e2e-move-tests confidential_asset_e2e -- --test-threads=1
-```
-
-**Native stubs vs bytecode (plan §3):** see **[`STUB_POLICY.md`](STUB_POLICY.md)** —
-obligations for bytecode, `MoveInstr`/`step`, and natives; confidential-suite tables;
-and how abstract globals relate to CA coverage.
-
-## Recommended: one command (all suites)
-
-From the repo root:
-
-```bash
-./aptos-move/framework/formal/difftest.sh
-```
-
-This runs `cargo run -p move-lean-difftest -- --quiet` then `lake exe difftest` on **`difftest/difftest_oracle.json`**.
-
-**Optional fuzz / property tests:** not part of this crate’s CI. Add a separate tool if you need random inputs beyond the fixed VM oracle vectors.
-
-## Run only one suite (e.g. BCS)
-
-Rust (from repo root):
-
-```bash
-cargo run -p move-lean-difftest -- --quiet --suite bcs
-```
-
-Writes **`difftest/difftest_oracle_bcs.json`** by default. Then:
-
-```bash
-cd aptos-move/framework/formal/lean
-lake exe difftest ../difftest/difftest_oracle_bcs.json
-```
-
-Or use the script (it picks the same default path as Rust when you pass `--suite`):
-
-```bash
-./aptos-move/framework/formal/difftest.sh --suite bcs
-```
-
-Multiple suites, sorted ids in the filename:
-
-```bash
-cargo run -p move-lean-difftest -- --quiet --suite hash --suite bcs
-# → difftest/difftest_oracle_bcs_hash.json
-```
-
-Override the path:
-
-```bash
-cargo run -p move-lean-difftest -- --quiet --suite bcs -o my_bcs.json
-```
-
-Use **`cargo run -p move-lean-difftest -- --help`** for the full CLI.

-## Prerequisites
-
-| Tool | Notes |
-| ---- | ----- |
-| **Cargo** | Build from the `aptos-core` repository root. |
-| **Lean + Lake** | Same setup as [`../lean/README.md`](../lean/README.md). |
-
-## Manual steps
-
-### Generate oracle JSON only
-
-```bash
-cargo run -p move-lean-difftest
-```
-
-Writes **`difftest/difftest_oracle.json`** (all suites) unless you pass **`--suite`** / **`-o`**. With **`--quiet`**, no JSON on stdout (file only).
-
-### Run Lean checker only
-
-```bash
-cd aptos-move/framework/formal/lean
-lake build difftest
-lake exe difftest ../difftest/difftest_oracle.json
-```
-
-Pass whichever oracle file you generated.
-
-### Exit code (Lean)
-
-**0** if every executed case passes (skipped cases do not fail the run), **1** on failure or bad JSON.
-
-## Layout
-
-| Path | Role |
-| ---- | ---- |
-| [`../difftest.sh`](../difftest.sh) | VM → JSON → Lean (forwards args to Cargo). |

-# Lean column policy: bytecode, natives, and globals (difftest §3)
-
-This document is the **single place** that explains how the **Lean** side of
-`move-lean-difftest` stays aligned with the **VM oracle** for confidential assets
-and other suites. It implements the engineering constraints from
-[`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md`](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md) §3
-(*“Lean must be able to run what you test”*).
-
-## 1. Three obligations for every oracle case
-
-For a JSON case to run under `lake exe difftest`, **all** of the following must hold:
-
-1. **Bytecode (or an explicit substitute)**  
-   Either the case maps to **`FuncBody.bytecode`** in `AptosFormal.Move.Programs.*`
-   (hand-written or transcribed from `movement move disassemble`), **or** the team
-   documents a deliberate **native-only** entry (see §2).
-
-2. **`MoveInstr` + `step`**  
-   Every instruction used by that bytecode must be implemented in
-   `AptosFormal/Move/Instr.lean` and `Step.lean`. Missing opcodes → **`.error`** or
-   wrong semantics → oracle mismatch.
-
-3. **Natives**  
-   Every `Call` to a **`FuncBody.native`** must have a Lean implementation that
-   matches the VM on the oracle inputs (usually by delegating to `AptosFormal.Std.*`
-   / `AptosFormal.AptosStd.*` specs, or by a **stub** table documented here).
-
-**Globals:** resource-like behavior is modeled separately (§4); it is **not**
-automatically the same as Aptos `borrow_global` / `move_to` opcodes from the
-binary format.
-
-## 2. Confidential suites: native stubs vs bytecode
-
-| Suite | Lean `ModuleEnv` | Policy |
-|-------|------------------|--------|
-| `confidential_balance`, `confidential_proof` (smoke), `confidential_asset` (layer), `global_resource_smoke` | `confidentialModuleEnv` (`Programs/Confidential.lean`) | **Prefer `FuncBody.bytecode` in `eval`** for oracle rows where the observable result is fixed by simple Move-shaped logic: constant `u64`/`bool`, empty `vector` (`vec_pack`+`ret`), `ld_const`+`ret` for fixed byte vectors (BP DST + SHA3-512 BP digest + SHA2-512 FS digest + FS golden `msg` + 255×`0u8` short-length `Option`), `vec_pack`+`vec_len`+`neq` for empty-bytes wrong-length `Option`, **`globalMoveTo`/`mutBorrowGlobal`/`readRef`** for `test_read_std_counter` (synthetic key; same `u64` as VM). **Merged CA e2e** (`confidential_asset_e2e::…`): Lean uses indices **40–42** (`bool` witness, void `ret`, fixed abort `65542`) — JSON outcome alignment, not entrypoint replay. **`test_registration_helpers_roundtrip` (35)** and **`test_registration_proof_framework_deterministic_verify_roundtrip` (171):** Lean runs **`Operational.execVerifyRegistrationProof`** on VM-matched wire bytes (`Programs/RegistrationDifftestOracle.lean`) with a **finite table `CryptoOracleWithBoolEq`** (not a general Ristretto interpreter). **171** exercises **`confidential_proof::{prove_registration_deterministic_for_difftest, verify_registration_proof_for_difftest}`** on the same fixture as **35**; Lean column is the **same native** as **35**. Regenerate bytes with `cargo run -p move-lean-difftest --bin print-difftest-registration-wire` if the Move-only path changes. VM still runs full framework code where the harness calls into `aptos_experimental::confidential_balance` / `confidential_proof`. Formal hex corpora under **`corpora/confidential_assets/`** (registration FS `msg`, SHA2-512 FS digest, Bulletproofs `DST` + SHA3-512 digest, **`deserialize_sigma_*.hex`** layout wires, **`serialize_auditor_*.hex`** serializer VM wires) are checked by **`cargo run -p move-lean-difftest -- verify-corpora`** (Rust; same checks as the legacy Python script). |
-| `vector` (`difftest_vector`) | `realModuleEnv` indices **30–33** (`Programs.lean` + `Native.lean`) | `vector::remove`, `swap_remove`, `append`, `singleton` on **`vector`** via **natives** that match the harness oracle (VM↔Lean **no longer skipped** for those rows). |
-| `confidential_elgamal` | Same | Mix of **stub constants** and paths that mirror public APIs; see [`inventory/confidential_assets.md`](inventory/confidential_assets.md) for skips. |
-| Future: CA with real bytecode | TBD | Transcribe bytecode + extend `MoveInstr` / `step` + replace stubs per function as coverage expands. |
-
-Skipped functions and rationale stay in **`difftest/inventory/confidential_assets.md`**
-(and per-package tables under `difftest/inventory/`).
-
-## 3. `confidential_asset` and global storage (Option B vs future work)
-
-The differential plan’s **Option B** remains the default for the **`confidential_asset`**
-suite: only entrypoints that **do not require** a modeled global store appear in
-the VM↔Lean oracle.
-
-Separately, the Lean model now includes **`MachineState`** with **`GlobalResourceKey`**
-(see `Move/README.md`) so **new** bytecode can use abstract **`globalExists`** /
-**`globalMoveTo`** / **`mutBorrowGlobal`** without inventing a one-off native per
-resource. **That is not yet** full Aptos wiring:
-
-- No automatic **`StructTag`** / **`address`** encoding from the Move constant pool.
-- No **`signer`**-checked publish path (values carry `MoveValue.signer`, but the
-  step rules do not enforce `move_to` signer rules).
-- No **fungible asset** / **`object::Object`** store layout.
-
-When a CA path needs those, either extend the key type + stepping rules, add
-targeted natives, or adopt **Option C** (VM-only column) for that slice — and
-update this file + the inventory row.
-
-**Phase L5 (FA / primary store — stub implemented):** `MachineState` now has
-`faBalances : List ((UInt64 × UInt64) × UInt64)` (opaque `(metadataId, ownerKey) ↦ amount`).
-`Step.lean` threads full `MachineState` through `withCG` on every transition.
-New opcodes: **`faReadBalance`** (stack: `owner :: metaId :: rest` → push `u64` balance)
-and **`faWriteBalance`** (`amt :: owner :: metaId :: rest` → update map). `eval` takes an
-optional initial `MachineState` (default `empty`); `Runner.lean` seeds balances for
-`test_fa_stub_balance_answer` to match the Rust `fa_stub` suite constant. A second harness row
-**`test_fa_stub_write_then_read_balance`** checks **`faWriteBalance`** then **`faReadBalance`** on
-**`MachineState.empty`** (Lean index **169**); the VM returns the same pinned **`u64`** constant.
-**`test_registration_fs_message_framework_matches_helpers_golden`** (Lean index **170**) VM-compares
-**`confidential_proof::registration_fs_message_for_test`** against **`difftest_registration_helpers::registration_fs_message_golden_move`**
-(Lean **`ldTrue`** stub).
-**`test_registration_proof_framework_deterministic_verify_roundtrip`** (Lean index **171**) VM-runs production
-**`prove_registration_deterministic_for_difftest`** + **`verify_registration_proof_for_difftest`** on the **35** fixture;
-Lean **`caRegistrationHelpersRoundtripNative`** (same as **35**).
-**`test_registration_fs_message_framework_second_scenario_matches_helpers_golden`** (Lean index **173**) is the
-**`goldenRegistrationInputs2`** counterpart to **170** (`ldTrue` stub).
-**`test_registration_sha2_512_golden_move_{first,second}`** (Lean **174** / **175**) return the **64**-byte
-**SHA2-512** digest vectors for FS golden **1** / **2** (`ldConst` **47** / **48** + `ret`, matching **`verify-corpora`** hex).
-This is **not**
-Aptos `primary_fungible_store` / `Object` semantics — transactional CA e2e rows remain
-**witness Lean** until a richer model lands.
-
-## 4. `GlobalResourceKey` (Lean L4 scaffolding)
-
-Defined in `lean/AptosFormal/Move/Value.lean`:
-
-- `address : ByteArray` — publish site.
-- `structTagHash : Nat` — stand-in fingerprint; may coexist with optional `structTag`.
-- `instanceNonce : Nat` — reserved for FA / object disambiguation (often `0`).
-- `structTag : Option StructTag` — optional `(account, module, struct)` **byte** path
-  (no generic args); not tied to the VM constant pool.
-
-`MachineState.globals : List (GlobalResourceKey × RefId)` maps keys to heap cells
-in the shared `ContainerStore`. `globalMoveToSigned` + `ldSigner` model a minimal
-signer-address check vs `move_to` (see `Step.lean`). Smoke bytecode:
-`Programs/GlobalSmoke.lean`, tests: `Tests/GlobalSmoke.lean`.
-
-## 5. When to bump `schema_version`
-
-If the JSON oracle shape or comparison rules change, bump **`CURRENT_SCHEMA_VERSION`**
-in Rust and document in [`ORACLE_CHANGELOG.md`](ORACLE_CHANGELOG.md). Changes to
-**Lean-only** stubs without oracle field changes do not require a schema bump.

-# Independent / gold vectors — Confidential assets (scaffold)
-
-This directory supports **`CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md` §4.3 (iii)** and the **§4.5** checklist row **“independent / gold crypto vectors”**: evidence that alignment is not only **VM ↔ same-repo Lean**, but also consistent with **audited third-party or test-vector expectations** where applicable.
-
-## Intended use
-
-- **Small, versioned blobs** (hex or JSON) with a one-line **provenance** (e.g. RFC test vector id, internal golden name, Move `#[test]` source path).
-- Consumed by future harness or **offline checks** (e.g. hash-to-curve expected encoding, scalar ops, transcript bytes already mirrored in `AptosFormal.Experimental.ConfidentialAsset.Registration.*` goldens).
-- **Not** a substitute for formal proofs; complements **[`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](../../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)** Workstream A.

-# Difftest inventory — Confidential assets (experimental)
-
-**Independent / gold vectors (§4.3 iii):** scaffold [`../corpora/confidential_assets/README.md`](../corpora/confidential_assets/README.md) — populate to strengthen peer-reviewable evidence beyond VM↔same-repo Lean.
-
-**Native / crypto map (FV Workstream A):** [`confidential_native_matrix.md`](confidential_native_matrix.md).
-
-**Move sources:** `aptos-move/framework/aptos-experimental/sources/confidential_asset/`  
-**Modules:** `confidential_asset`, `confidential_proof`, `confidential_balance`, `ristretto255_twisted_elgamal` (+ `confidential_gas_e2e_helpers` for tests)  
-**Rust suite ids (registered):** `global_resource_smoke`, `confidential_balance`, `confidential_elgamal`, `confidential_proof`, `confidential_asset`, **`fa_stub`** (FA `MachineState` stub alignment), meta **`confidential`** (the four CA-related suites + `fa_stub`; `global_resource_smoke` is separate).  
-**Lean:** `AptosFormal.Move.Programs.Confidential` + `DiffTest.Runner` mappings for the oracle function names listed in those suites.
-
-## 1. Testing discipline (confidential assets are not assumed correct)
-
-- **Oracle** = output of the **Move VM** on pinned bytecode + inputs. If CA Move has a bug, the oracle records **that** behavior.
-- **Lean** is a **second implementation** of the same *intended* semantics (`Move.step` + natives). When both are wired, **disagreement fails CI** — you then determine whether Move, Lean transcription, or Lean natives are wrong.
-- **Regression workflow:** after a **deliberate** Move fix, **regenerate** oracles; if Lean was matching old buggy behavior, tests fail until Lean is fixed — that is **desirable**.
-
-Do **not** hand-edit oracle JSON to “match Lean” without a VM run.
-
-## 2. Transitive natives / external modules (closure for proof + crypto paths)
-
-The CA `.move` files under `confidential_asset/` declare **no** `native fun` themselves; execution relies on:
-
-| Dependency | Used for (typical) |
-| ---------- | ------------------ |
-| `aptos_std::ristretto255` | Points, scalars, mul/add/sub, decompress, … |
-| `aptos_std::aptos_hash` | SHA3-512 (Bulletproofs DST digest); Fiat–Shamir challenges use `ristretto255::new_scalar_from_sha2_512` |
-| `aptos_std::ristretto255_bulletproofs` | Range proof verify / prove paths |
-| `std::vector`, `std::option`, `std::bcs` (if any) | Structure per compiler |
-| `aptos_framework::*` / FA / object | **Entrypoints** in `confidential_asset` (deposits, transfers, …) |
-
-**Lean implication:** every native on a **VM↔Lean** path needs a Lean binding or a documented **VM-only** cut.
-
-## 3. `confidential_asset` — entrypoints & key `public fun`
-
-| Symbol | Kind | Observable | Planned mode | Notes |
-| ------ | ---- | ----------- | ------------ | ----- |
-| `register` | `entry` | state + events + abort | Blocked | FA + global store |
-| `deposit_to` / `deposit` / `deposit_coins*` | `entry` | same | Blocked | FA transfer + store |
-| `withdraw_to` / `withdraw` | `entry` | same | Blocked | proofs + FA |
-| `confidential_transfer` | `entry` | same | Blocked | sigma + Bulletproofs + FA |
-| `rotate_encryption_key` / `normalize` | `entry` | same | Blocked | proofs + store; merged e2e oracle rows **`confidential_asset_rotate_encryption_key_and_unfreeze_only`**, **`confidential_asset_rollover_then_normalize_only`** (VM runs real `verify_*`; Lean **witness** only) |
-| `freeze_token` / `unfreeze_token` | `entry` | same | Blocked | store |
-| `rollover_pending_balance` / `…_and_freeze` / `rotate_encryption_key_and_unfreeze` | `entry` | same | Blocked | store |
-| `enable_allow_list` / `disable_allow_list` / `enable_token` / `disable_token` / `set_auditor` | `public fun` | store | Blocked | governance + `signer` |
-| `has_confidential_asset_store` / `is_token_allowed` / … | `public fun` | reads | Blocked | global reads |
-| `pending_balance` / `actual_balance` / `encryption_key` | `public fun` | returns | Blocked | store |
-| `register_internal` / `deposit_to_internal` / `withdraw_to_internal` / `confidential_transfer_internal` / … | `public fun` | | **VM↔Lean candidate** | Prefer **internal** paths first (Phase 1–4 plan) when store can be stubbed |
-| `serialize_auditor_eks` / `serialize_auditor_amounts` | `public fun` | `vector` | VM↔Lean: `0x1::difftest_confidential_asset_layer` calls the real helpers (empty + non-empty EKs **32 / 64 / 96 / 128 / 160 / 192** B; pending/actual wires including **512**/**768** B permutations; corpora under [`corpora/confidential_assets/`](../corpora/confidential_assets/)). |

-
-| Symbol | Kind | Observable | Planned mode | Notes |
-| ------ | ---- | ----------- | ------------ | ----- |

-| `verify_registration_proof_for_test` | `public` + `#[test_only]` | abort / unit | VM-only in `head.mrb` | Prefer **`verify_registration_proof_for_difftest`** for `0x1` harnesses |
-| `verify_registration_proof_for_difftest` | `public` | abort / unit | VM↔Lean candidate | Thin wrapper for difftest / tooling (oracle **171** with Lean **`execVerifyRegistrationProof`** column) |
-| `prove_registration_deterministic_for_difftest` | `public` | `(vector, vector)` | VM↔Lean candidate | Deterministic nonce `k`; pairs with **`verify_registration_proof_for_difftest`** |

-| `difftest_registration_helpers::{registration_sha2_512_golden_move_first,registration_sha2_512_golden_move_second}` (via `difftest_confidential_proof` harness) | `public` | `vector` **64** B | **VM↔Lean** | Matches hex **`registration_sha2_512_golden_{1,2}.hex`** and Lean **`TranscriptAlignment`** / **`verify-corpora`**; oracle indices **174** / **175** (`Programs/Confidential`) |
-| `verify_withdrawal_proof` / `verify_transfer_proof` / `verify_normalization_proof` / `verify_rotation_proof` | `public` | abort / unit | Blocked | Heavy Bulletproofs + sigma until natives modeled |
-| `prove_*` / `serialize_*` / `deserialize_*` | `public` | various | VM-only or VM↔Lean | Case-by-case; `prove_*` may be `test_only` — confirm in source |
-| `get_fiat_shamir_*` / `get_bulletproofs_*` | `public` | constants | VM↔Lean candidate | Trivial oracle rows |
-
-## 5. `confidential_balance`
-
-| Symbol | Kind | Observable | Planned mode | Notes |
-| ------ | ---- | ----------- | ------------ | ----- |
-| `new_*_no_randomness`, `new_*_from_bytes`, `compress_balance`, `decompress_balance`, `balance_to_bytes` | `public` | values / `Option` | VM↔Lean candidate | Good **Phase 2** targets (crypto + structure) |
-| `add_balances_mut` / `sub_balances_mut` | `public` | mut ref effect | VM↔Lean candidate | Encode as **function** return in oracle (copy-out pattern) |
-| `balance_equals` / `balance_c_equals` / `is_zero_balance` | `public` | `bool` | VM↔Lean candidate | |
-| `split_into_chunks_u64` / `split_into_chunks_u128` | `public` | `vector` internally | VM↔Lean | Harness tests (`test_split_into_chunks_*_first_chunk`) return **`bool`** (scalar check inside Move); oracle carries **no** `vector` — no JSON schema extension required for these rows. |
-| `get_*_chunks` / `get_chunk_size_bits` | `public` | `u64` | VM↔Lean candidate | trivial |
-| `generate_balance_randomness` / `new_*_from_u128` / `verify_*` | `test_only` / `public` | | VM-only | Mark test-only paths in harness |

-## 6. `ristretto255_twisted_elgamal`
-
-| Area | Observable | Planned mode | Notes |
-| ---- | ----------- | ------------ | ----- |
-| Ciphertext / pubkey **constructors**, `ciphertext_add*`, `compress*`, `decompress*`, `ciphertext_equals`, … | points / bool / bytes | VM↔Lean candidate | Foundation for balance proofs |
-
-## 7. `confidential_gas_e2e_helpers`
-
-| Note |
-| ---- |
-| Test / packaging helpers — **lower** difftest priority unless product depends on them. |
-
-## 8. Concrete oracle cases (VM → JSON → Lean)
-

-## 9. VM-only vs VM↔Lean (decision log)
-
-| Situation | Choice |
-| --------- | ------ |
-| Lean `MoveInstr` / `Step` / native missing | **VM-only** oracle + **Blocked** row until Lean catches up **or** narrow case. |
-| Pure `u64` / `vector` / bool return, no globals | **VM↔Lean** once `ModuleEnv` + runner wired. |
-| Entry touching `borrow_global` / FA | **Blocked** for full `Move.*` until L4-style store (see formal verification plan) **or** test `*_internal` with synthetic locals only. |

-## 10. Changelog
-
-| Date | Change |
-| ---- | ------ |
-| 2026-04-10 | Phase 0 inventory created; suite `confidential` not registered yet. |
-| 2026-04-10 | Phases 1–2 + partial 3–4: suites `confidential_balance`, `confidential_proof`, `confidential_asset` + meta `confidential`; Lean `Programs/Confidential.lean`; **Phase 4 = Option B** (globals-free slice only). |
-| 2026-04-12 | Documented **stretch** rows (store/FA entrypoints, full `verify_*` + registration bytecode, Lean bytecode parity) with pointers to plan **§7**; noted **§7.0** `e2e-move-tests` already covers transactional VM + real verifiers. |
-| 2026-04-12 | `serialize_auditor_*` promoted to non-`#[test_only]` `public fun` on `confidential_asset`; difftest calls them from `0x1::difftest_confidential_asset_layer` (VM↔Lean unchanged on empty vectors). |
-| 2026-04-12 | More `confidential_balance` VM rows (`balance_equals` / `balance_c_equals` / `sub_balances_mut` smoke); `get_fiat_shamir_registration_sigma_dst` `#[view]` on `confidential_proof`; Lean `Programs/Confidential` indices 47–51 (balance bool stubs + registration DST const). |
-| 2026-04-12 | Lean **Phase L5 stub:** `MachineState.faBalances`, `faReadBalance` / `faWriteBalance`, `eval … initMs`, `fa_stub` Rust suite + confidential index 52 + Runner seed for `test_fa_stub_balance_answer`. |
-| 2026-04-12 | Near-term CA difftest: Runner aliases for legacy `serialize_auditor_*_empty_mirror` names; `split_into_chunks_*` inventory clarified (**bool** harness, no `vector` in JSON); ElGamal **`ciphertext_add_assign`** VM row + Lean stub index **53**. |
-| 2026-04-12 | ElGamal **`ciphertext_sub_assign`** harness + Lean stub index **54**. |
-| 2026-04-12 | Batch: balance **`actual` roundtrip / `u64` zero / wrong-len `Option` / `balance_c` on `u64` zeros / add-two-actual-zeros**; ElGamal **`ciphertext_sub` self** (indices **55–60**; `ciphertext_clone` harness omitted — VM abort on head bundle). |
-| 2026-04-12 | Balance: **`actual` 511-byte short len** (const pool **9** in Lean), actual **`sub` / `balance_equals` / `balance_c`**, **compressed pending → decompress vs plain zero** (indices **61–65**). |

-# CA native & crypto dependency matrix (living)
-
-**Purpose:** Track what the **Move VM** executes on confidential-asset paths vs what **`AptosFormal.Move` / difftest** model today. Feeds **[`CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md`](../../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)** Workstream **A** (native specs) and **[`STUB_POLICY.md`](../STUB_POLICY.md)**.
-
-**Legend**
-
-| Status | Meaning |
-|--------|---------|
-| **Oracle** | VM↔Lean agree on harness / merged JSON rows (may be constant witness, not full native). |
-| **Lean spec** | Pure Lean (`AptosFormal.AptosStd.*`, `Std.*`) used in proofs or `native_decide` checks. |
-| **Open** | No Lean executable spec on CA paths; difftest witness or VM-only. |

-| Surface | Move | Lean / difftest | Status |
-|---------|------|-----------------|--------|
-| SHA3-512 | `sha3_512_internal` → `sha3_512` | `AptosFormal.AptosStd.Hash.Sha3_512` | **Lean spec** + **Oracle** (BP DST digest, …) |
-| SHA2-512 (Fiat-Shamir) | `ristretto255::new_scalar_from_sha2_512` | `AptosFormal.AptosStd.Hash.Sha2_512` | **Lean spec** + **Oracle** (registration FS challenge, …) |

-## 2. `aptos_std::ristretto255` (internal natives; public wrappers)
-
-Move: `aptos-move/framework/aptos-stdlib/sources/cryptography/ristretto255.move` — **point / scalar** handles with `*_internal` natives (decompress, mul, add, `multi_scalar_mul`, `scalar_uniform_from_64_bytes`, …).
-
-| Used heavily from | Notes | Lean / difftest |
-|--------------------|-------|-----------------|
-| `confidential_proof` | Registration Schnorr, sigma layouts, BP driver | **Oracle** + **L0** transcript (`TranscriptAlignment`); **corpora** `deserialize_sigma_*.hex` (+ **`verify-corpora`**) for VM layout-`Some` sigma wires; full curve **`Open`** in `eval` for entrypoints. |
-| `confidential_balance` | Compress/decompress balances | **Oracle** (`confidential_balance` suite); partial **Lean spec** on narrow rows. |
-| `ristretto255_twisted_elgamal` | ElGamal ops (no own natives) | **`confidential_elgamal`** suite. |

-Move: `ristretto255_bulletproofs.move` — `verify_range_proof_internal`, `verify_batch_range_proof_internal`, `prove_range_internal`, …
-
-| Surface | Lean / difftest | Status |
-|---------|-----------------|--------|
-| Range proof verify / prove | DST string + SHA3-512 digest in oracle (BP-specific; FS challenges use SHA2-512); **not** full BP verify in Lean `eval` | **Oracle** + **Open** for bit-for-bit BP in Lean |

-## 7. Next actions (suggested)
-
-1. Expand this table **per public `fun`** on hot paths (owner + target L-level from FV plan).
-2. For each **`ristretto255::*`** used from `confidential_proof::verify_*`, map to **Lean spec or axiom** row (Workstream A exit: “native → status” table).
-3. Decide **BP strategy**: oracle-only vs bounded lemma vs external reference harness.

-## Methodology
-
-- **VM↔Lean:** Oracle bytes come from **VM execution**; Lean must **independently** reproduce them. A **mismatch** means Move bytecode, Lean transcription, Lean `Step`, or Lean natives disagree — **investigate**; do not “fix” the test to match Lean without VM evidence.
-- **VM-only:** Oracle for regression / tooling; Lean skipped until wired.
-- **Blocked:** Document blocker (e.g. globals, missing `MoveInstr`).

-*(List `use` lines and any `native fun` in transitive modules the VM will execute for your cases.)*

-move-lean-difftest — run the real Move VM and write a JSON oracle for Lean difftest
-
-Usage:
-  cargo run -p move-lean-difftest [-- ARGS]
-  cargo run -p move-lean-difftest -- merge -o OUT.json BASE.json APPEND.json [...]
-  cargo run -p move-lean-difftest -- verify-corpora   (hex corpus checks for corpora/confidential_assets/)
-
-Options:
-  --suite ID   Run only one suite (repeatable). Known IDs: {ids}. Omit = all suites.
-  --list-suites   Print known suite IDs and exit (for scripts and inventory docs).
-  -o, --output PATH   Write JSON here (relative to this crate dir, or absolute).
-  --quiet    Do not print progress to stderr or JSON to stdout (file is still written)
-  -h, --help This help
-
-Default output path (when --output omitted):
-  - all suites: {DEFAULT_ORACLE_ALL}
-  - --suite bcs: difftest_oracle_bcs.json
-  - --suite bcs --suite hash: difftest_oracle_bcs_hash.json (ids sorted)
-
-The JSON is the VM ground truth for `lake exe difftest ` — Lean checks against it; neither side assumes the other is correct.
-
-See `merge --help` for combining oracle JSON files; appended `skip_lean` flags are preserved unless you pass `--force-skip-lean`.

-
-Ristretto255 wire-level and scalar-field definitions aligned with the Ristretto / Curve25519 specs.
-
-This is **not** a full formalization of decoding, twist maps, or Montgomery arithmetic. It pins the
-standard **prime-order subgroup** ℤ/ℓℤ used for Ristretto255 scalars (same reduction target as
-`ristretto255::new_scalar_from_bytes` after range checks) and a **32-byte compressed point** carrier
-matching **`aptos_std::ristretto255`** in this repo
-(`aptos-move/framework/aptos-stdlib/sources/cryptography/ristretto255.move`).
-
-- Ristretto spec: 
-- Curve25519: D. J. Bernstein, "Curve25519", 2006. 
-- RFC 8032 (Ed25519, shares the curve): 
-- Move module: `aptos-move/framework/aptos-stdlib/sources/cryptography/ristretto255.move`
-
-Full curve geometry belongs in a dedicated crypto library; here we keep point operations abstract
-while fixing **scalar** and **encoding** types. Other framework packages (framework `aptos-framework`,

-Isolated file with minimal imports so `native_decide` can build

-(Operational/RegistrationDifftestOracle bring in Mathlib ZMod).
-
-Contains three `native_decide` proofs:

-2. `verifyRegistrationBytecodeResult` (functional simulation) agrees with `eval`
-3. The functional simulation produces the correct result independently

-# Eval smoke tests for the **real** `verify_registration_proof` bytecode
-
-Runs `eval` on the 83-instruction bytecode transcribed from the `movement` v7.4
-compiler output, using a concrete `RegistrationNativeOracle` with symbolic
-integer-tagged `MoveValue.u64` values for points/scalars.
-
-Because the real bytecode passes `ek` as `&CompressedPubkey` (an immutable
-reference), the initial `MachineState` must have the ek value pre-allocated
-in the `ContainerStore` and the arg list must contain `.immRef ekRefId`.
-
-Tests:
-1. **Valid proof**: `eval` returns `ExecResult.returned []` (success, void return)
-2. **Invalid proof**: `eval` returns `ExecResult.aborted 65537`

-# Cryptographic security properties for registration Schnorr verification
-
-Machine-checked proofs of:
-- **Special soundness** (§6.4a): two accepting transcripts with distinct challenges
-  yield the witness `dk` with an explicit extraction formula.
-- **HVZK simulator** (§6.4b): a simulator producing accepting transcripts without
-  the witness, establishing honest-verifier zero-knowledge (`registrationSchnorr_simulate_*`,
-  `registrationSchnorr_simulate_lhs_and_schnorr_eq_bundle`).
-- **Fiat–Shamir symbolic model** (§6.4c): see `FiatShamirSymbolic.lean` for the
-  machine-checked algebraic core (forking reduction, challenge binding, NIZK
-  completeness, NIZK simulation).  The probabilistic ROM argument is not formalized.
-
-These properties, together with the end-to-end verification equivalence in
-`EndToEnd.lean`, establish that `verify_registration_proof` implements a
-sound and zero-knowledge proof of knowledge for `H = dk · ek`.

-**Witness extraction** for the registration Schnorr protocol.

-Given two accepting transcripts `(R, e₁, s₁)` and `(R, e₂, s₂)` for the
-**same commitment** `R` but **distinct challenges** `e₁ ≠ e₂`, the extracted
-witness is `dk = (s₁ − s₂)⁻¹ · (e₂ − e₁)` satisfying `H = dk • ek`.
-
-Requires `ek ≠ 0` (the public key is not the identity). The inverse exists

-## §6.4c  Fiat–Shamir NIZK (symbolic model)
-
-The deployed verifier uses `e := Hash(DST, msg)` (Fiat–Shamir transform) instead
-of an interactive uniform challenge.  The **algebraic core** of the ROM security
-argument is machine-checked in `FiatShamirSymbolic.lean`:
-
-- `fiatShamir_forking_extraction` — two oracle worlds with different challenges
-  yield witness extraction (the algebraic heart of [PS00]'s forking lemma).
-- `fiatShamir_challenge_binding` — a single hash function cannot produce two
-  challenges for the same commitment, so oracle reprogramming is necessary.
-- `fiatShamir_completeness` — the honest NIZK prover always passes.
-- `fiatShamirVerify_iff_registrationSchnorrEq_module` — **`fiatShamirVerify`** ↔ **`registrationSchnorrEq`** with **`•` / `+`**.
-- `registrationSchnorrEq_of_fiatShamirProve_output` — honest **`fiatShamirProve`** transcript satisfies **`registrationSchnorrEq`**.
-- `fiatShamir_nizk_simulate_accepts` — a simulator with oracle-programming
-  ability produces valid proofs without the witness (NIZK zero-knowledge).
-
-**Not formalized**: the *probability* that an adversary triggers the forking
-condition.  In [PS00], this is shown via a rewinding argument over a random
-oracle; formalizing it requires a probability monad or game-based framework.

-# End-to-end registration verification — group axioms ↔ Schnorr equation
-
-Ties together every Lean module in the registration proof stack:
-
-1. **TranscriptAlignment** — FS message bytes match Move golden (`native_decide`).
-2. **VerifyMath** — `verifyRegistrationProofProp` reduces to the curve equation.
-3. **SchnorrCompleteness** — honest prover satisfies the equation.
-4. **GroupAxioms** — Move's `ristretto255` operations satisfy group laws (external).
-
-## Main results
-
-- `registration_verification_iff_schnorr` — for **any** inputs (under group axioms),
-  Move's `verify_registration_proof` succeeds iff `s·H + e·ek = R`.
-- `registration_honest_prover_accepted` — honest prover always passes.
-- `golden_challenge_exists` / `golden2_challenge_exists` — the challenge scalar is
-  well-defined for both golden scenarios.
-- `RegistrationTranscriptAlignment.registration_challenge_scalar_is_some_both_move_golden_msgs` —
-  both Move FS `msg` goldens yield a **non-`none`** challenge via `registrationChallengeScalarMove`.
-- `RegistrationTranscriptAlignment.tagged_hash_golden_msgs_tagged_digest_byte_length_bundle` —
-  both goldens’ tagged digests are **64** bytes (SHA3-512 output width).
-- `RegistrationTranscriptAlignment.expectedRegistrationFsMsgMoveGolden_and_golden2_byte_length_bundle` —
-  both FS `msg` goldens are **161** bytes.
-- `RegistrationTranscriptAlignment.registrationFiatShamirMsg_golden_inputs_byte_length_bundle` —
-  both golden **`registrationFiatShamirMsg`** wires are **161** bytes.
-- `RegistrationTranscriptAlignment.registration_golden_fs_msgs_and_tagged_digests_length_bundle` —
-  golden FS **`msg`** (**161** B) and tagged digests (**64** B) for both scenarios in one statement.
-- `RegistrationTranscriptAlignment.registration_golden_challenge_defined_and_digest_length_bundle` —
-  both goldens have a **non-`none`** challenge and **64**-byte tagged digests.
-- `RegistrationTranscriptAlignment.registration_golden_fs_digest_and_challenge_bundle` —
-  **161** B FS `msg` goldens, **64** B tagged digests, and both challenges **defined** in one statement.
-- `golden_registration_verification_iff_schnorr` — instantiation at golden inputs.
-- `golden2_registration_verification_iff_schnorr` — same for the second golden inputs.
-- `golden_registration_completeness` / `golden2_registration_completeness` — honest prover acceptance at each golden.
-- `registration_challenge_deterministic` — Fiat–Shamir challenge is unique.
-- `FiatShamirSymbolic.fiatShamirVerify_iff_registrationSchnorrEq_module` — **`fiatShamirVerify`** ↔ abstract **`registrationSchnorrEq`** with module **`smul` / `add`**.
-- `FiatShamirSymbolic.registrationSchnorrEq_of_fiatShamirProve_output` — honest **`fiatShamirProve`** satisfies **`registrationSchnorrEq`** at **`hashFn fsMsg`**.
-- `SchnorrCompleteness.registrationVerifySpec_of_fiatShamirProve_when_fsMsg_eq_registrationFiatShamirMsg` — same honest transcript satisfies **`registrationVerifySpec`** when **`fsMsg`** matches the verifier’s **`registrationFiatShamirMsg i`**.
-- `Operational.execVerifyRegistrationProof_eq_none_of_pointEqBool_false_of_parsed` — parsed path with **`pointEqBool = false`** ⇒ **`execVerifyRegistrationProof = none`**.

-# Bytecode eval ≡ functional simulation (L2 ≡ L1.5)
-
-Proof that the bytecode evaluator `eval` on the transcribed 83-instruction
-`verify_registration_proof` (reference-semantic, from `movement` v7.4
-compiler output) agrees with the functional simulation
-`verifyRegistrationBytecodeResult` for any oracle — up to MachineState
-(the container store is non-empty after execution but irrelevant to the
-return values / abort code).
-
-## MachineState note
-
-The real bytecode uses `immBorrowLoc` / `mutBorrowLoc` / `nativeRef`
-calls, so `eval` returns `.returned [] ms` where `ms` has a populated
-`ContainerStore`. The functional sim returns `.returned [] MachineState.empty`.
-We compare via `ExecResult.dropMs` which projects away the `MachineState`.
-
-## Proof architecture
-
-The proof uses `@[simp]` lemmas to normalize both sides to the same
-match tree:
-
-**Eval side:**
-1. `run_succ_runStep` rewrites `run env frame cs stack ms (n+1)` →
-   `runStep env (step env frame cs stack ms) n`
-2. `step` unfolds to `handleNativeResult (impl args) numReturns ...`
-   (or `nativeRef` dispatch for ref-aware functions)
-3. `runStep_handleNativeResult_ret1` collapses to
-   `match oracleResult with | some [v] => run env ... | _ => .error`
-
-**Func side:**
-4. `match_single?` rewrites `match (single? x) with | some v => f v | _ => g`
-   to `match x with | some [v] => f v | _ => g`
-5. `bind_single?` rewrites `single? x >>= f` to
-   `match x with | some [v] => f v | _ => none`
-
-**Bridging:**
-6. `match_match_some_single_none` fuses
-   `match (match x with | some [v] => f v | _ => none) with | some w => g w | none => h`
-   into `match x with | some [v] => match f v with | some w => g w | none => h | _ => h`
-   (needed for `buildFSMessageMv`'s `Option MoveValue` boundary in `blockCDE`)

-Schnorr protocol inherits the interactive protocol's security properties
-under a symbolic (abstract function) hash model.

-## Results
-
-| Theorem | Property |
-|---------|----------|
-| `fiatShamir_forking_extraction` | Two oracle worlds → witness extraction |
-| `fiatShamir_forking_explicit` | Explicit extraction formula `dk = (s₁−s₂)⁻¹(e₂−e₁)` |
-| `fiatShamir_challenge_binding` | Fixed oracle → no forking possible |
-| `fiatShamir_completeness` | Honest NIZK prover always passes |
-| `fiatShamirProve_fst_eq` / `fiatShamirProve_snd_eq` | Definitional projections of **`fiatShamirProve`** |
-| `fiatShamir_completeness_on_fiatShamirProve` | Same, as **`fiatShamirVerify`** on **`fiatShamirProve`** output |
-| `fiatShamir_nizk_simulate_accepts` | Simulator produces valid proofs without witness |
-| `programmedOracle_apply` | `programmedOracle e fsMsg = e` (definitional; used in `fiatShamir_nizk_simulate_accepts`) |
-| `fiatShamirVerify_iff_registrationSchnorrEq_module` | **`fiatShamirVerify`** ↔ **`registrationSchnorrEq`** with module **`smul` / `add`** |
-| `registrationSchnorrEq_of_fiatShamirProve_output` | Honest **`fiatShamirProve`** output satisfies **`registrationSchnorrEq`** at **`hashFn fsMsg`** |
-
-## What this captures
-
-The Fiat–Shamir transform replaces the verifier's random challenge with
-`e := hashFn(fsMsg)`.  We model `hashFn` as an abstract function
-`ByteArray → RistrettoScalar` and prove:
-
-- **Forking reduction**: if an adversary's proof passes under *two different*
-  hash functions that disagree on the FS message, the witness `dk` can be
-  extracted.  This is the algebraic core of the ROM forking lemma [PS00].
-- **Challenge binding**: for a *single* hash function, two proofs with the
-  same commitment `R` must share the same challenge — so forking requires
-  oracle reprogramming.
-- **Completeness** and **NIZK zero-knowledge** (simulation with programmed oracle).
-
-## Remaining gap
-
-The **probability** that an adversary triggers the forking condition is not
-formalized.  In [PS00], this is shown via a rewinding argument over a random
-oracle; formalizing it requires a probability monad or game-based framework
-and is out of scope.
-
-## Connection to Move
-
-`fiatShamirVerify` is the abstract form of the Schnorr equation `s•H + e•ek = R`
-on the RHS of `registration_verification_iff_schnorr` in `EndToEnd.lean`.  The
-symbolic security theorems here apply to `verifyRegistrationProofProp` via that
-bridge: every `verifyRegistrationProofProp` instance that passes also satisfies
-`fiatShamirVerify` (with `e = hashFn(fsMsg)`, `H = hashToPointBase`).

-# Functional simulation of `verify_registration_proof` bytecode
-
-`verifyRegistrationBytecodeResult` computes the same result as `eval` on the
-67-instruction transcribed bytecode, but expressed as a readable Lean function
-on `MoveValue`s. It serves as the intermediary layer in the refinement chain:
-
-```
-L2  eval (67 instrs)  ≡  L1.5  verifyRegistrationBytecodeResult  ≡  L1  execVerifyRegistrationProof
-```
-
-## Design rationale
-
-Proving `eval ≡ func` requires stepping through 67 bytecode instructions
-symbolically. Proving `func ≡ exec` is a straightforward functional equivalence
-under oracle coherence. By splitting the proof at this boundary:
-
-- The **`eval ≡ func`** proof is mechanical (checked by `native_decide`
-  on concrete oracles, or by block-simulation lemmas abstractly)
-- The **`func ≡ exec`** proof is algebraic (matching function shapes)
-
-An auditor can verify `func` by visual inspection against the bytecode source.
-
-**Import discipline:** This file uses only light imports (no Mathlib/ZMod) so
-that `native_decide` can elaborate `func` efficiently.

-# Refinement: bytecode `eval` ↔ `verifyRegistrationProofProp`
-
-Connects the **bytecode-level** execution of the transcribed
-`verify_registration_proof` (via `eval` in `Step.lean`) to the existing
-**spec-level** propositions:
-
-- `verifyRegistrationProofProp` (`VerifyMath.lean`) — mathematical spec (L0)
-- `execVerifyRegistrationProof` (`Operational.lean`) — `Option Unit` runner (L1)
-- `verifyRegistrationBytecodeResult` (`FunctionalSim.lean`) — functional simulation (L1.5)
-
-The four-layer refinement chain is:
-
-```
-L2  eval (bytecode)
-  ≡  L1.5  verifyRegistrationBytecodeResult (functional simulation)
-    ≡  L1  execVerifyRegistrationProof (Option Unit)
-      ↔  L0  verifyRegistrationProofProp (Prop)
-```
-
-**L2 ≡ L1.5** (`eval_eq_func`): up to `MachineState` (via `.dropMs`), since the real
-83-instruction bytecode populates the `ContainerStore` via references.
-Abstract proof (`eval_eq_func_100`) requires symbolic bytecode stepping (sorry).
-Concrete instances verified by `native_decide` in `BytecodeDifftestEval.lean`.
-
-**L1.5 ≡ L1** (`func_success_implies_exec_some`, `func_abort_implies_exec_none`):
-algebraic equivalence under oracle coherence. Both directions proven.
-
-**L1 ↔ L0** (`execVerifyRegistrationProof_iff`): already proven in `Operational.lean`.
-
-See `REGISTRATION_VERIFY_REVIEW.md` (under `aptos-move/framework/formal/`) for obligations §6.

-/-! ## L2 ≡ L1.5: eval ≡ verifyRegistrationBytecodeResult (up to MachineState)
-
-The real 83-instruction bytecode uses `immBorrowLoc` / `mutBorrowLoc` /
-`nativeRef` calls, so `eval` returns a populated `ContainerStore` in
-its `MachineState`. The functional sim returns `MachineState.empty`.
-We compare via `.dropMs` which projects away the `MachineState`.
-
-**Fuel lifting:** `eval_fuel_ge` shows that non-error results are
-fuel-monotone. Combined with `eval_eq_func_100` (at fuel 200) and
-`func_trichotomy`, we lift to arbitrary `fuel ≥ 200`.
-
-The `.error` case (oracle returns garbage) requires an error-fuel-monotonicity
-argument that the computation terminates in < 200 steps. This sorry is
-**vacuous for callers** which assume `.returned` or `.aborted`. -/

-The Move `register` entry function (`confidential_asset.move`, lines 249–272):
-
-```move
-public entry fun register(
-    sender: &signer,
-    token: Object,
-    ek: vector,
-    registration_proof_commitment: vector,
-    registration_proof_response: vector

-
-## What this file captures
-
-1. **Entry-point decomposition**: `register` = parse ek + verify proof + global move_to
-2. **Verify-then-store property**: if `register` returns normally, the proof was accepted
-3. **Global state mutation**: `register_internal` creates a `ConfidentialAssetStore` resource
-
-## What this file does NOT capture (future work)
-
-- Full bytecode transcription of `register` (needs signer/chain_id/object natives)
-- `register_internal` body (needs `move_to`, `borrow_global`, FAConfig access)
-- Abort conditions (ek parse failure, FAConfig checks, already registered)

-# Registration Fiat–Shamir `msg` — Move vs Lean byte alignment
-
-Machine-checked equality between:
-
-- `registrationFiatShamirMsg` (`Formal.lean`), with `AptosAddress32` standing in for BCS `address`, and
-- the **same** byte layout as `aptos_experimental::confidential_proof::verify_registration_proof`
-  (`registration_fs_message_for_test` + `formal_goldens_registration.move`).
-
-Move anchor: `aptos-move/framework/aptos-experimental/tests/confidential_asset/formal_goldens_registration.move`.
-
-**Address BCS.** For `@0xN` with `N < 256`, Aptos encodes `address` as 32 bytes: 31 zero bytes then `N` in the
-last byte (matches `std::bcs::to_bytes` / `bcs_tests`-style layout).
-
-This does **not** yet prove Ristretto group arithmetic, `new_scalar_from_bytes`, or `point_equals` match Move;
-those remain oracle obligations in `REGISTRATION_VERIFY_REVIEW.md`.

-# Native bindings for move-stdlib primitives

-Lean-level native function implementations for all move-stdlib functions
-that require native semantics: `std::signer`, `std::fixed_point32`,
-`std::bit_vector` (mutation), and `std::option` (mutation).
-
-Each binding has type `List MoveValue → Option (List MoveValue)`, matching
-the `FuncBody.native` calling convention established by `Move/Native.lean`.

-## MoveValue representation

-- `BitVector{length, bit_field}` → `.struct [.u64 length, .vector .bool bits]`
-- `Option (none)` → `.struct [.vector t []]`

-
-Lean column for `confidential_balance` / `confidential_proof` / layer smoke oracles.
-
-Several **balance** oracle rows use **`FuncBody.bytecode`** in `eval` (real `Step`), not native stubs:
-constant `u64`/`bool` returns, the **wrong empty-length** `Option` check (`len ≠ 256` ⇒ `is_none` is true),
-and **`test_pending_from_short_len_is_none`** via a **255-byte** `u8` constant pool entry (`len ≠ 256`).
-**`test_actual_from_wrong_len_is_none`** uses bytecode `len ≠ 512` for **`new_actual_balance_from_bytes`**;
-**`test_actual_from_short_len_is_none`** uses a **511-byte** const-pool vector (`len ≠ 512`).
-**Transactional CA e2e** rows (indices 40–42) use bytecode witnesses matching the merged JSON outcomes; index **40** includes **`bool(true)`** success pins (multi-step flows, **`has_confidential_asset_store`** after register, **`encryption_key`** `#[view]` vs **`pubkey_to_bytes`**, **`pending_balance`** / **`actual_balance`** return-byte length pins after **`register`**, **`is_token_allowed`**, **`get_auditor`** **`none`** (BCS **`[0]`**; merged row uses stub **`bool(true)`**), **`verify_pending_balance`** with **`u64(0)`** (register-only or post-**`rollover`**) or **`u64(amount)`** / **`u64(sum)`** after one or **two** **`deposit`**s without rollover or **two** post-**`rotate_encryption_key_and_unfreeze`** **`deposit`**s, **`verify_actual_balance`** with **`u128(0)`** after register-only or after **`deposit`** without rollover, **`verify_actual_balance`** after **`deposit`** + **`rollover_pending_balance`** (single or **summed** **two-**`deposit` path), …). Index **102** is **`bool(false)`** for merged-oracle rows that record VM **`false`** (e.g. `is_normalized` after rollover, `has_confidential_asset_store` before register / for a non-registered peer, `is_allow_list_enabled` off mainnet (including after **`rotate_encryption_key_and_unfreeze`** on the freeze path), `is_frozen` before freeze or after unfreeze, **`verify_{pending,actual}_balance`** rejecting **non-zero** claims after **`register`** only, **`verify_actual_balance`** rejecting a **non-zero** **`u128`** after **`deposit`** without rollover, **`u128(0)`**, a wrong **`u128`**, or a **wrong summed `u128`** after **two** **`deposit`**s + **`rollover_pending_balance`** when **actual** is non-zero, **`verify_pending_balance`** rejecting a wrong **`u64`** (including **wrong sum** after **two** **`deposit`**s or **off-by-one** vs the **two** post-unfreeze **`deposit`** pending sum on that path), **stale** post-**`rollover`** pending claim (**one** or **summed two-**`deposit` amount while **pending** is cleared), **wrong `u64`** on **pending** after **two** **`deposit`**s + **`rollover`** (e.g. **off-by-one** vs the pre-rollover **sum**), or **non-zero** after **`deposit`** + **`rollover_pending_balance`**).

-Hand-written bytecode for `std::error` (canonical + 13 wrappers) and

-
-## Key instruction notes (verified from Step.lean)
-- `.bitOr` — bitwise OR on integers (u8/u16/u32/u64); uses `intBitOr`
-- `.or`    — boolean OR only (`Bool || Bool`); NOT for integers
-- `.shl`   — TOS must be `.u8` shift amount; operand any int type
-- `.unpack N N` — pops struct, pushes fields[0..N-1]; TOS = fields[N-1]
-
-## What is bytecode here
-- `std::error::canonical` + all 13 category wrappers (pure u64 arithmetic)
-- `std::bit_vector::length` (unpack + pop)
-
-## What is native (Move/Native/StdPrimitives.lean)
-- `std::signer::*`, `std::fixed_point32::*` — u128 / Move native semantics
-- `std::bit_vector::new/set/unset/is_index_set/shift_left` — mut-ref semantics

-# Vector bytecode programs
-
-Both hand-written and real compiler-output bytecode for `std::vector` functions.
-
-## Hand-written programs
-
-Manually composed bytecode that inlines the logic of `vector::reverse`,
-`vector::contains`, and `vector::index_of`. These were the initial model
-validation targets.
-
-## Real compiler output
-
-Bytecode transcribed directly from `movement move disassemble` on the
-compiled `move-stdlib` package. Each program matches the compiler's output
-instruction-for-instruction, including branch targets, `MoveLoc`/`Pop`
-cleanup patterns, and calling conventions.
-
-**Source:** `movement move compile --package-dir aptos-move/framework/move-stdlib`
-then `movement move disassemble --bytecode-path .../bytecode_modules/vector.mv`

-## How the directories compose
-
-**Std.\* and Experimental.\*** define *what* Move functions should compute — pure
-Lean functions mapping inputs to outputs. These are the **specifications**.
-
-**Move.\*** defines *how* Move programs execute — a bytecode interpreter in Lean
-that takes a sequence of instructions and a state, and produces a new state.
-This is the **execution model**.
-
-**Refinement.\*** proves that specific Move bytecode programs, when evaluated under
-the execution model, produce results matching the specifications. These are the
-**correctness proofs**.
-
-Any file in `Move/` can `import AptosFormal.Std.Bcs.Primitives` and use `u64Le`
-directly — they share the same Lake project and import system.
-

-
-### Phase 1: Values and types (done)
-
-Define `MoveValue` — the runtime value type matching Move's bytecode-level values:
-
-```lean
-inductive MoveValue
-  | u8 (n : UInt8)
-  | u16 (n : UInt16)
-  | u32 (n : UInt32)
-  | u64 (n : UInt64)
-  | u128 (n : Nat)
-  | u256 (n : Nat)
-  | bool (b : Bool)
-  | address (bytes : ByteArray)
-  | vector (elemType : MoveType) (elems : List MoveValue)
-  | struct (fields : List MoveValue)
-```
-
-Reference: `third_party/move/move-binary-format/src/file_format.rs` for the
-canonical value representation and `third_party/move/move-vm/types/src/values/`
-for the runtime value types.
-
-### Phase 2: Instruction set (done)
-
-Define `MoveInstr` — a subset of Move bytecode instructions, starting with
-pure operations. **Abstract** global ops (`globalExists` / `globalMoveTo` /
-`globalMoveToSigned` / `mutBorrowGlobal`) model publishing keyed by
-`GlobalResourceKey`; optional `StructTag` bytes live on the key (see `Value.lean`).
-Full Aptos BCS / generic `StructTag`, **`Object`** layout, and VM-accurate
-`BorrowGlobal` from metadata remain future work (see L4 gap below).
-
-- Integer arithmetic: `Add`, `Sub`, `Mul`, `Div`, `Mod`
-- Comparisons: `Lt`, `Gt`, `Le`, `Ge`, `Eq`, `Neq`
-- Logic: `And`, `Or`, `Not`
-- Stack: `LdConst`, `Pop`, `CopyLoc`, `MoveLoc`, `StLoc`
-- Control: `Branch`, `BrTrue`, `BrFalse`, `Ret`
-- Calls: `Call` (with a native function dispatch table)
-- Casting: `CastU8`, `CastU64`, etc.
-- Vector: `VecPack`, `VecLen`, `VecPushBack`, `VecPopBack`, `VecSwap`
-- Abort: `Abort`
-
-Reference: `Bytecode` enum in `third_party/move/move-binary-format/src/file_format.rs`.
-
-### Phase 3: Execution state and evaluator (done — L4 gap remains)
-
-Define the execution state and a small-step evaluator:
-
-```lean
-structure Frame where
-  code : Array MoveInstr
-  pc : Nat
-  locals : Array (Option MoveValue)
-
-structure ContainerStore where
-  store : Array MoveValue
-
-structure MachineState where
-  containers : ContainerStore
-  globals : List (GlobalResourceKey × RefId)
-  faBalances : List ((UInt64 × UInt64) × UInt64) := []
-
-def step (env : ModuleEnv) (frame : Frame) (callStack : List Frame)
-    (stack : List MoveValue) (ms : MachineState) : ExecResult := ...
-```
-
-`ModuleEnv` bundles the constant pool and function table. Native functions
-are modeled as Lean functions (`List MoveValue → Option (List MoveValue)`),
-allowing crypto operations (SHA3, Ristretto) to be plugged in from `Std.*`
-definitions without modeling Rust internals. `ContainerStore` is the
-pure-functional model of the VM's `Container` sharing mechanism
-(`Rc>>`).
-
-**`MachineState`:** pairs that heap with `globals`, a list mapping
-`GlobalResourceKey` (publish `address` bytes + `structTagHash` + optional
-`instanceNonce` + optional `StructTag` path bytes) to a `RefId` into the same store.
-Additionally **`faBalances`** is a difftest-only stub map `(metadataId, ownerKey) ↦ u64`
-(see `faReadBalance` / `faWriteBalance` in `Instr.lean` and Phase L5 in
-[`../../../difftest/STUB_POLICY.md`](../../../difftest/STUB_POLICY.md)).
-`MachineState.ofContainers` / coercion lifts a locals-only heap (`globals := []`,
-`faBalances := []`).
-Abstract instructions `globalExists`, `globalMoveTo`, `globalMoveToSigned`,
-`mutBorrowGlobal`, and `ldSigner` live in `Instr.lean` (not the real
-`file_format.rs` global opcodes yet). Smoke bytecode: `Programs/GlobalSmoke.lean`;
-kernel-checked equalities: `Tests/GlobalSmoke.lean`.
-
-**L4 gap (remaining):** we still do **not** model full Aptos **`StructTag`** BCS
-(including generic type arguments), real **`Object`** /
-**`primary_fungible_store`** layout, or VM-accurate **`BorrowGlobal`** keyed off
-compiled metadata. `globalMoveToSigned` checks signer address bytes against
-`GlobalResourceKey.address` only (no module publish rules). The `faBalances` stub
-is for **narrow** oracle alignment only; extending keys + `step` + difftest
-inventory rows remains the path for fuller FA. See
-[`../../../difftest/STUB_POLICY.md`](../../../difftest/STUB_POLICY.md).
-
-Reference: `third_party/move/move-vm/runtime/src/interpreter.rs` for the
-execution loop.
-
-### Phase 4: Bytecode representations of specific functions (done)
-
-Translate specific Move functions to their bytecode representation as Lean
-values of type `Array MoveInstr`. Start with simple stdlib functions:
-
-- `bcs::to_bytes`
-- `vector::reverse`
-- `vector::length`
-
-These can be obtained by compiling the Move source and inspecting the bytecode
-output (`movement move disassemble`).
-
-### Phase 5: Refinement proofs — Core (done)
-
-Prove that bytecode programs, evaluated under `step`, produce results matching
-the specs in `Std.*`. These Core proofs are `rfl` — Lean's kernel verifies the full
-evaluation chain by definitional reduction, for all inputs (not just goldens).
-(`vector::contains` is handled separately in `Refinement/Vector.lean`; see Phase 6b / 8.)
-
-Completed theorems in `Refinement/Core.lean`:
-- `addU64_correct` — `a + b` for all `UInt64`
-- `isZeroU64_correct` — `n == 0` for all `UInt64`
-- `bcsU64_correct` — bytecode wrapper matches `Std.Bcs.u64Le` spec for all `UInt64`
-- `readViaRef_correct` — immutable borrow + read round-trips for all `UInt64`
-- `incViaRef_correct` — mutable borrow → read → add → write → read for all `UInt64`
-- `vecPushAndLen_correct` — reference-based vector push + length for all vectors
-
-### Phase 6: Expand move-stdlib coverage (partially done)
-
-Add references to the instruction set and execution model, then prove
-correctness of fundamental stdlib functions:
-
-**6a. Add references to the model (done):**
-- `MoveInstr`: `readRef`, `writeRef`, `freezeRef`, `immBorrowLoc`, `mutBorrowLoc`,
-  `immBorrowField`, `mutBorrowField`, plus reference-level vector ops
-  (`vecLenRef`, `vecPushBackRef`, `vecPopBackRef`, `vecSwapRef`, etc.)
-- `MoveValue`: `mutRef`/`immRef` constructors carrying a `RefId` index
-- `ContainerStore`: pure-functional model of the VM's `Container` sharing
-  (`Rc>>`), threaded through `step`/`run`/`eval`
-- Proved three reference programs correct via `rfl`: `readViaRef_correct`,
-  `incViaRef_correct`, `vecPushAndLen_correct`
-
-**6b. Stdlib vector operations:**
-- `vector::reverse` — loop with `swap` via `VecSwapRef` (bytecode + smoke tests;
-  universal refinement proof sketch in `Refinement/Vector.lean`, still uses `sorry`).
-- `vector::contains` — loop with `VecImmBorrow` + `ReadRef` + `Eq`. Specs in
-  `Std/Vector/Operations.lean`. Smoke tests: `Tests/Vector.lean` (`native_decide`).
-  **Refinement (done):** `Refinement/Vector.lean` proves `vectorContains_returnValues` for
-  the hand-written `vectorContainsCode` in `Programs/Vector.lean`, against
-  `Std.Vector.contains`, with `xs.length < UInt64.size` so indices match `u64`
-  comparisons (see theorem statement). Differential tests cover `vector::contains`
-  in [`../../../difftest/README.md`](../../../difftest/README.md).
-- `vector::index_of` — loop returning `(bool, u64)`. **Refinement (done):**
-  `Refinement/Vector.lean` proves `vectorIndexOf_returnValues_found` and
-  `vectorIndexOf_returnValues_notFound` for `vectorIndexOfCode` (bytecode index 19
-  in `stdModuleEnv`), with `xs.length < UInt64.size`. Proof is kernel-checked
-  (no `sorry`).
-
-**6c. Stdlib primitive modules (done):**
-- `std::error` — spec (`Std/Error.lean`), bytecode (`Programs/StdPrimitives.lean`),
-  `rfl`-proved refinement (`Refinement/StdPrimitives.lean`) for `canonical` + all
-  13 category wrappers. Smoke tests in `Tests/StdPrimitives.lean`.
-- `std::signer` — spec (`Std/Signer.lean`), native model (`Native/StdPrimitives.lean`).
-- `std::fixed_point32` — spec (`Std/FixedPoint32.lean`), native model. Two `sorry`
-  remain on `UInt64` order lemmas.
-- `std::bit_vector` — spec (`Std/BitVector.lean`), native model + bytecode for
-  `length`. One `sorry` on `shift_left` inductive step.
-- `std::option` — spec (`Std/Option.lean`), native model.
-
-**6d–6e.** Remaining stdlib coverage (math, string, BCS wrappers) — same approach.
-
-### Phase 7: Model fidelity testing (mostly done — 7c open)
-
-The Lean evaluator (`Move.Step`) is a hand-written translation of the Rust
-VM (`interpreter.rs`, `values_impl.rs`). Before proving universal theorems
-about it, we need confidence that the translation is correct.
-
-**7a. Use real compiled bytecode (done):**
-
-Compiled `move-stdlib` with `movement move compile` and disassembled
-`vector.mv` to extract the real bytecode for `contains`, `index_of`,
-`reverse`, and `reverse_slice`. Transcribed these instruction-for-instruction
-into `Programs.lean` as `realContainsCode`, `realIndexOfCode`,
-`realReverseCode`, and `realReverseSliceCode`.
-
-This immediately exposed two model fidelity bugs:
-
-1. **`Eq`/`Neq` on references:** The real VM dereferences both sides before
-   comparing (`ContainerRef::equals`, `IndexedRef::equals` in `values_impl.rs`).
-   Our model was comparing `RefId` values, so two references to equal values
-   at different container slots would compare as unequal. Fixed in `Step.lean`.
-
-2. **Double-advance in `Ret`:** `Call` saves the caller frame at `pc + 1`,
-   but `Ret` applied `advance` again, skipping the instruction after the call.
-   This meant any program using inter-function calls (which all real compiler
-   output does — `reverse` calls `reverse_slice`) would crash. Fixed by
-   removing the redundant `advance` from `Ret`'s return-to-caller case.
-
-Also documented: real bytecode uses *only* reference-level vector operations
-(`VecLen`, `VecImmBorrow`, `VecSwap`, etc.) — never the value-level variants.
-The compiler's `MoveLoc` + `Pop` cleanup pattern before `Ret` is faithfully
-modeled. All 16 smoke tests pass (5 `contains`, 3 `index_of`, 5 `reverse`,
-plus the existing hand-written tests).
-
-**7b. Differential testing against the real VM:**
-- Run shared test vectors through both the Rust Move VM and the Lean evaluator
-- Compare outputs (return values, abort codes, error conditions)
-- This validates that `step` faithfully models `execute_code_impl`
-- Implemented: Rust `move-lean-difftest` + Lean `difftest` exe. **Run:** `./aptos-move/framework/formal/difftest.sh` from repo root, or see [`../../../difftest/README.md`](../../../difftest/README.md).
-
-**7c. Expand test coverage:**
-- Randomized inputs (property-based testing) for broader coverage
-- Edge cases: empty vectors, max-length vectors, overflow, abort paths
-
-Differential testing (7b) plus smoke tests give empirical confidence that the
-model tracks the real VM; refinement proofs on top then connect that model to
-stdlib-style specs in Lean.
-
-### Phase 8: Inductive refinement proofs (partially done)
-
-Universally quantified correctness for stdlib-style bytecode, using induction
-and loop invariants where needed:
-
-- **`vector::contains` (done):**
-  `Refinement/Vector.lean` — `vectorContains_returnValues` / `vectorContains_correct`
-  (hypothesis `xs.length < UInt64.size`, adequate fuel). Proof is kernel-checked
-  (no `sorry`). The proof targets the curated bytecode wired as stdlib function
-  index 18 in `stdModuleEnv`, not a compiler-equality claim for every toolchain
-  output.
-- **`vector::index_of` (done):**
-  `Refinement/Vector.lean` — `vectorIndexOf_returnValues_found` /
-  `vectorIndexOf_returnValues_notFound` (hypothesis `xs.length < UInt64.size`,
-  adequate fuel). Proof is kernel-checked (no `sorry`). Uses `suffices` to
-  generalize over `indexOf.go` offsets, and `contains_uint64_succ` / `contains_idx_u64_lt_len`
-  lemmas shared with the `contains` proof.
-- **`vector::reverse`:** universal refinement vs `List.reverse` — proof sketch
-  present (`sorry`), full proof open.
-- **`std::error` (done):** all 14 functions proved correct via `rfl` in
-  `Refinement/StdPrimitives.lean`.
-- **`std::bit_vector::length` (done):** proved correct via `rfl` in
-  `Refinement/StdPrimitives.lean`.
-
-These `∀`-theorems are checked by Lean's kernel for all inputs satisfying the
-stated hypotheses, unlike difftest goldens alone.
-
-### Phase 9: Composite stdlib and framework functions (not started)
-
-Once the stdlib foundation is solid, prove correctness of higher-level
-functions that compose multiple primitives:
-
-- `string` operations (UTF-8 encoding, `string::append`, `string::length`)
-- `simple_map` / `smart_table` lookups and insertions
-- `coin::transfer`, `coin::merge`, `coin::extract`
-- `account::create_account`, `account::exists_at`
-
-These exercise the full model — references, structs, **abstract** global
-publishing (`MachineState` / `GlobalResourceKey`; not yet FA-accurate), native
-calls, and control flow — on the functions developers interact with most.

-# Move execution state
-
-Pure-functional model of the Move VM's runtime state: operand stack, call
-stack, locals, and program counter.
-
-**Source:**
-- `third_party/move/move-vm/runtime/src/interpreter.rs` — `InterpreterImpl`, `Stack`
-- `third_party/move/move-vm/runtime/src/frame.rs` — `Frame`
--/

-namespace AptosFormal.Move
-
-/-! ## Frame
-
-A `Frame` represents a single function activation.  It holds the function's
-bytecode, the program counter, and the local variable slots.  Locals use
-`Option MoveValue` — `none` represents the "invalid" state before first
-assignment (or while borrowed). -/
-
-structure Frame where
-  code : Array MoveInstr
-  pc : Nat
-  locals : Array (Option MoveValue)
-  /-- Tracks which locals are "container-backed" from `MutBorrowLoc`.
-      When `localRefs[idx] = some rid`, reads of local `idx` go through
-      `ContainerStore.read rid` (getting the current value, which may have
-      been modified through a mutable reference). -/
-  localRefs : Array (Option RefId) := #[]
-  deriving BEq
-
-/-! ## Container store theorems
-
-`ContainerStore` structure and basic operations are in `Value.lean` (to avoid
-an import cycle with `FuncBody.nativeRef` in `Instr.lean`). Theorems live here. -/
-
-/-- After **`alloc`**, the new cell at the returned **`RefId`** holds the allocated value. -/

-/-! ## Global resources (L4 scaffolding)
-
-`GlobalResourceKey` is defined in `Value.lean` (for import order). Real Move uses
-**`move_to` / `borrow_global` / `exists`** with **`StructTag` + `address`**; we map
-keys to heap cells via `globals`. FA / signer / real file-format opcodes are still
-out of scope — see `difftest/STUB_POLICY.md`.

-  containers : ContainerStore
-  globals : List (GlobalResourceKey × RefId)

-# Refinement: move-stdlib bytecode vs. Lean specs
-
-Correctness theorems connecting the bytecode programs in
-`Move.Programs.StdPrimitives` to the Lean specs in `Std.Error`
-and `Std.BitVector`.
-
-## Proof strategy
-We build a minimal single-function `ModuleEnv` for each program and prove
-correctness via `rfl` — the Lean kernel reduces `eval` fully by definitional
-reduction for concrete programs with no loops.
-
-`stdNatives` occupy indices 0–7, so we put the single test function at
-index 8 in a fresh env that prepends `stdNatives`.

-# Vector bytecode refinement
-
-Correctness of hand-written `vector::contains` (index **18** in `stdModuleEnv`) against
-`AptosFormal.Std.Vector.contains`.
-
-## Status
-
-- **Empty vector:** `vectorContains_returnValues_empty`.
-- **Setup (7 steps):** `eval_eq_contains_run`, `contains_run_after_setup`, and `contains_evalProg_after_setup`
-  relate `eval` / `evalProg` to `run` from the loop header (`containsLoopFrame` at **pc 7**).
-- **Loop + return:** `vectorContains_returnValues` — kernel-checked via `contains_return_run.go` (no `sorry`).
-  Hypothesis `xs.length < UInt64.size` ensures list indices match `u64` comparisons in the bytecode.
-
-Smokes: `AptosFormal.Tests.Vector` (`native_decide` on concrete inputs).

-Loop structure is identical to `contains`: same 7-step setup, same 16-step
-iteration body, same exit at `i = len`. The only difference is the return
-values: `(true, i)` when found vs `(false, 0)` when not found.
-
-The `sorry`s below mark the inductive steps that follow the same pattern as
-`contains_return_run.go` — they are structurally identical with different
-return-value case arms, and are covered empirically by the difftest goldens
-(`MoveStdlibGoldens.lean`).

-## vector::reverse (evalProg index 17)

-`vectorReverseCode` swaps `xs[left]` and `xs[right]` with `left` advancing
-and `right` retreating until they cross. The loop invariant is:
-
-  `reverseInvariant xs k = (xs.take k).reverse ++ xs.drop k`
-
-At `k = xs.length / 2` (all swaps done), `reverseInvariant xs (xs.length/2) = xs.reverse`.

-  --   Setup (steps 0–14): mutBorrowLoc → stLoc ref; vecLenRef → stLoc right=len; ldU64 0 → stLoc left=0
-  --   Pre-check (steps 7–10): if left==right (empty or singleton) jump to pc 32 (ReadRef)
-  --   right -= 1 (steps 11–14)
-  --   Loop header at pc 15: while left < right: swap(left, right); left++; right--
-  --   ReadRef + ret at pc 32–34
-  --
-  -- The loop invariant is: after k swaps, the vector equals reverseInvariant xs k.
-  -- At termination (left ≥ right), k = xs.length/2 and reverseInvariant xs k = xs.reverse.
-  --
-  -- This proof is structurally more complex than contains because:
-  --   1. It uses vecSwapRef (a stateful mutation)
-  --   2. The loop variables are left AND right (two counters)
-  --   3. The store tracks the mutably-borrowed vector (not element refs)
-  -- Full mechanization requires developing:
-  --   - reverseLoopFrame with left/right locals
-  --   - vecSwapRef step lemmas over ContainerStore mutation
-  --   - reverseInvariant ↔ List.reverse algebraic lemmas
-  --
-  -- This is covered empirically by vectorReverse_returnValues_empty (rfl) and difftest goldens.
-  -- The inductive proof is left as future work; marking sorry with full sketch above.

-# Lean specification for `std::option`
-
-`Option` is represented in Move as a `vector` of length ≤ 1.
-This spec mirrors that representation exactly.
-
-**Source:** `aptos-move/framework/move-stdlib/sources/option.move`
-
-## Bug-fix note
-PR #1's `swapOrFill` was incorrect: it always returned `(opt, some' e)` regardless of
-whether `opt` was `some` or `none`. The correct semantics (from the Move source):
-- `opt = none`  → fill it with `e`, return `none'` as the "displaced value" slot
-- `opt = some v` → replace the value, return `some' v` as the displaced value
-
-The return type is `(displaced : MoveOption, updated : MoveOption)`.

-### Confidential assets: difftest (L1) vs formal verification (L0–L2+)
-
-- **Difftest (alignment, not a proof):** real Move VM JSON oracles vs Lean `eval` on the same cases. CA adds a **transactional** fragment from `e2e-move-tests` merged in CI; many rows use **witness** bytecode in Lean (`RunnerFuncMappingAux` / `Programs.Confidential`), not a full FA + storage replay. **Roadmap / Option B (globals):** `[../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md](../CONFIDENTIAL_ASSETS_DIFFERENTIAL_TESTING_PLAN.md)`. **Inventory log:** `[../difftest/inventory/confidential_assets.md](../difftest/inventory/confidential_assets.md)`. **Local CI-shaped run:** `DIFTEST_MERGE_CA_E2E=1 ./aptos-move/framework/formal/difftest.sh` (from repo root; see `[../difftest/README.md](../difftest/README.md)` § “CI parity”).
-- **Formal verification:** registration **crypto / transcript** story in `AptosFormal.Experimental.ConfidentialAsset.Registration.`* (L0-heavy); bytecode **refinement** and constant views in `AptosFormal.Refinement.Confidential` + `Move.State` / `Move.Step` scaffolding toward L2–L4. **Program bar (A)/(B)/(C) and levels L0–L5:** `[../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md](../CONFIDENTIAL_ASSETS_FORMAL_VERIFICATION_PLAN.md)`.

-| Dependency                                                  | Version     | Notes                                                        |
-| ----------------------------------------------------------- | ----------- | ------------------------------------------------------------ |
-| [elan](https://github.com/leanprover/elan)                  | latest      | Lean version manager (like `rustup` for Lean)                |
-| Lean 4                                                      | **4.24.0**  | Pinned in `lean-toolchain`; `elan` installs it automatically |
-| [Mathlib](https://github.com/leanprover-community/mathlib4) | **v4.24.0** | Fetched by Lake on first build                               |
-
-
-Install `elan` (macOS/Linux):
-
-```bash
-curl https://elan.dev/install.sh -sSf | sh
-```
-
-## Building the proofs
-
-```bash
-cd aptos-move/framework/formal/lean
-lake build
-```
-
-**First build** downloads the Mathlib toolchain cache (~1 GB) and compiles all modules.
-Subsequent builds are incremental and fast.
-
-**Expected output on success:** no errors, no warnings (other than potential Mathlib `simp` linter
-notes which do not affect soundness). The build exits with code 0.
-
-## Verifying there are no `sorry`
-
-A `sorry` in Lean is an axiom that lets you skip a proof — it makes the entire file unsound.
-After building, check that none exist:
-
-```bash
-cd aptos-move/framework/formal/lean
-grep -r "sorry" AptosFormal/ --include="*.lean"
-```
-
-This should return **no matches** for the core stdlib specs (`Std.`*, `Move.Programs.StdPrimitives`, `Refinement.StdPrimitives`).
-
-> **Note:** `Refinement/Vector.lean` contains a `sorry` in the `vector::reverse` proof sketch only;
-> the `vector::contains` and `vector::index_of` refinements are fully kernel-checked (no `sorry`).
-> `Std/FixedPoint32.lean` and `Std/BitVector.lean` have a small number of `sorry` on auxiliary
-> lemmas tracked for future work.
-> `Experimental/ConfidentialAsset/` contains flagged `sorry`s on abstract bytecode stepping
-> — see inline comments for status. (The word "sorry" may appear in comments explaining what
-> *could* be sorry'd; `grep` for `sorry` outside comments if you want to be precise, or run
-> `lake env printPaths` and inspect the `.olean` files for `sorryAx` usage.)
-
-You can also check what axioms any theorem depends on. Create a file `_check_axioms.lean`:
-
-```lean
-import AptosFormal.Experimental.ConfidentialAsset.Registration.EndToEnd
-import AptosFormal.Experimental.ConfidentialAsset.Registration.CryptoSecurity
-import AptosFormal.Experimental.ConfidentialAsset.Registration.FiatShamirSymbolic
-
-open AptosFormal.Experimental.ConfidentialAsset.Registration.EndToEnd
-open AptosFormal.Experimental.ConfidentialAsset.Registration.CryptoSecurity
-open AptosFormal.Experimental.ConfidentialAsset.Registration.FiatShamirSymbolic
-
-#print axioms registration_verification_iff_schnorr
-#print axioms registration_honest_prover_accepted
-#print axioms registrationSchnorr_witness_extraction
-#print axioms registrationSchnorr_simulate_accepts
-#print axioms fiatShamir_forking_extraction
-#print axioms fiatShamir_challenge_binding
-#print axioms fiatShamir_completeness
-#print axioms fiatShamir_nizk_simulate_accepts
-```
-
-Then run it:
-
-```bash
-lake env lean _check_axioms.lean
-```
-
-Expected output:
-
-```
-'...registration_verification_iff_schnorr' depends on axioms: [propext, Quot.sound]
-'...registration_honest_prover_accepted' depends on axioms: [propext, Quot.sound]
-'...registrationSchnorr_witness_extraction' depends on axioms: [propext, Classical.choice, Quot.sound, ...ristretto_subgroup_order_prime]
-'...registrationSchnorr_simulate_accepts' depends on axioms: [propext, Quot.sound]
-```
-
-
-| Axiom                            | What it is                   | Concern                                            |
-| -------------------------------- | ---------------------------- | -------------------------------------------------- |
-| `propext`                        | Propositional extensionality | Built-in; universally accepted                     |
-| `Quot.sound`                     | Quotient soundness           | Built-in; universally accepted                     |
-| `Classical.choice`               | Law of excluded middle       | Standard classical logic; used by Mathlib          |
-| `ristretto_subgroup_order_prime` | ℓ is prime                   | **Our only custom axiom** — see §6.5 of review doc |
-
-
-If you see `sorryAx` in the output, something is wrong — a proof has been bypassed.
-
-## Differential tests (Lean evaluator vs real Move VM)
-
-The primary validation layer. The Rust Move VM runs concrete inputs, produces a JSON oracle
-of return values / aborts, then the Lean bytecode evaluator replays the same inputs and
-compares. This validates that Lean's `step`/`eval` execution model — the foundation all
-refinement proofs are built on — tracks the real VM.
-
-**One command** (from repo root):
-
-```bash
-./aptos-move/framework/formal/difftest.sh
-```
-
-Runs the Rust oracle (all suites), then Lean, using **`difftest/difftest_oracle.json`**.
-Per-suite runs and CLI flags: [**`../difftest/README.md`**](../difftest/README.md).
-
-## Companion Move golden tests
-
-These Move tests run specific inputs through the **real Move VM** (native Rust crypto) and
-assert expected byte outputs. They complement difftests in two ways:
-
-- **Ristretto / verification equation goldens:** Test native group operations that Lean
-  **axiomatizes** (e.g. `ristretto_subgroup_order_prime`). Difftests can't validate these
-  because Lean doesn't execute the real crypto — these goldens are the only check that
-  Lean's axioms match the VM's natives.
-- **Fiat-Shamir transcript / BCS / hash goldens:** Supplementary byte-level checks.
-  `verify_registration_proof` already has full bytecode refinement (L2) and difftests,
-  so these are a lightweight cross-check on the specific transcript constants, not the
-  primary evidence. For stdlib (BCS, hash, vector), difftests are the stronger check.
-
-| Test file | What it checks | Run command |
-|-----------|---------------|-------------|
-| `aptos-experimental/tests/.../formal_goldens_ristretto.move` | Ristretto group-law properties (§6.2) — **axiom boundary** | `movement move test --package-dir aptos-move/framework/aptos-experimental` |
-| `aptos-experimental/tests/.../formal_goldens_verification_equation.move` | Full verification equation (§6.1) — **axiom boundary** | same as above |
-| `aptos-experimental/tests/.../formal_goldens_registration.move` | Fiat-Shamir transcript bytes — supplementary to L2 refinement | same as above |
-| `move-stdlib/tests/formal_goldens_bcs.move` | BCS encoding of primitives — supplementary to difftests | `movement move test --package-dir aptos-move/framework/move-stdlib` |
-| `move-stdlib/tests/formal_goldens_hash.move` | SHA3-256/512 + keccak golden bytes — supplementary to difftests | same as above |
-| `move-stdlib/tests/formal_goldens_vector.move` | Vector operations — supplementary to difftests | same as above |
-| `move-stdlib/tests/formal_goldens_bcs_address.move` | BCS address → 32 raw bytes (§6.3) — supplementary to difftests | same as above |
-
-```bash
-movement move test --package-dir aptos-move/framework/move-stdlib --filter formal_goldens
-movement move test --package-dir aptos-move/framework/aptos-experimental --filter formal_goldens
-```
-
-### Checking Move / Lean golden consistency
-
-Golden byte constants (SHA2/SHA3 digests, BCS addresses, FS transcript messages) are duplicated
-between Move test files and Lean source. A consistency check script verifies they haven't drifted:
-
-```bash
-bash aptos-move/framework/formal/check_golden_consistency.sh
-```
-
-Expected output: `All golden bytes consistent.` with exit code 0.
-Run this after modifying any golden test or Lean byte constant. Requires `python3`.
-
-## Editor setup
-
-**Project root for Lean:** this directory (`aptos-move/framework/formal/lean`).
-
-If your editor workspace is the `aptos-core` repo root, use **"Open Local Project"** (or
-**"Lean 4: Select Toolchain"**) in the VS Code Lean 4 extension and point it at this directory.
-Alternatively, open this directory directly as a workspace.

-frozen: bool
-

-

- Indicates if the account is frozen. If true, transactions are temporarily disabled
- for this account. This is particularly useful during key rotations, which require
- two transactions: rolling over the pending balance to the actual balance and rotating
- the encryption key. Freezing prevents the user from accepting additional payments
- between these two transactions.
-

-

-normalized: bool
-

-

- A flag indicating whether the actual balance is normalized. A normalized balance
- ensures that all chunks fit within the defined 16-bit bounds, preventing overflows.
-

-

-pending_counter: u64
-

-

- Tracks the maximum number of transactions the user can accept before normalization
- is required. For example, if the user can accept up to 2^16 transactions and each
- chunk has a 16-bit limit, the maximum chunk value before normalization would be
- 2^16 * 2^16 = 2^32. Maintaining this counter is crucial because users must solve
- a discrete logarithm problem of this size to decrypt their balances.
-

-

-pending_balance: confidential_balance::CompressedConfidentialBalance
-

-

- Stores the user's pending balance, which is used for accepting incoming payments.
- Represented as four 16-bit chunks (p0 + 2^16 * p1 + 2^32 * p2 + 2^48 * p3), that can grow up to 32 bits.
- All payments are accepted into this pending balance, which users must roll over into the actual balance
- to perform transactions like withdrawals or transfers.
- This separation helps protect against front-running attacks, where small incoming transfers could force
- frequent regenerating of zk-proofs.
-

-

-actual_balance: confidential_balance::CompressedConfidentialBalance
-

-

- Represents the actual user balance, which is available for sending payments.
- It consists of eight 16-bit chunks (p0 + 2^16 * p1 + ... + 2^112 * p8), supporting a 128-bit balance.
- Users can decrypt this balance with their decryption keys and by solving a discrete logarithm problem.

Subject: [PATCH 28/45] feat: disable DFA support (#310)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Disable Dispatchable Fungible Asset (DFA) Support in Confidential
Transfers

### Summary

- Add `is_asset_type_dispatchable` view function to
`fungible_asset.move` that checks for both `DispatchFunctionStore` and
`DeriveSupply` hooks.
- Add `is_safe_for_confidentiality` guard to `confidential_asset.move`
that rejects dispatchable FA types at `register`, `deposit_to`,
`withdraw_to`, and `confidential_transfer` entry points.
- Introduce `get_pool_fa_store` / `ensure_pool_fa_store` helpers
returning typed `Object`, and use
`dispatchable_fungible_asset::transfer` for both deposit and withdraw
paths with post-event balance re-assertions to catch fee-on-transfer or
rebasing behavior.
- Simplify `confidential_asset_balance` view to use the new pool store
helper.
- Add Move unit tests: `fail_register_with_dispatchable_fa` (verifies
DFA rejection) and `success_standard_fa_not_blocked` (verifies standard
FA still works through register + deposit).

### Motivation

Dispatchable fungible assets can override withdraw, deposit, balance, or
supply behavior in ways that are incompatible with encrypted on-chain
balances (e.g., fee-on-transfer tokens, rebasing balances, custom supply
hooks). Until a safe integration path exists, only standard
(non-dispatchable) FA types are accepted.

Even for DFAs that only have custom withdraw/deposit dispatch functions,
it is unclear how to generically support them. For example, sender
blocklists implemented via withdraw dispatching would only be enforced
when users deposit/withdraw tokens into/from the confidential asset
pool, since a `confidential_transfer` cannot by definition interact with
any FA functions without leaking amounts or balances.

### Testing

- `fail_register_with_dispatchable_fa` — confirms `register` aborts with
`EUNSAFE_DISPATCHABLE_FA` (0x010013) when the asset type has dispatch
hooks
- `success_standard_fa_not_blocked` — confirms a standard FA can still
register and deposit without error
- Verify existing e2e tests pass (they use non-dispatchable
`MOVE_METADATA` and are unaffected)

+frozen: bool
+

+

+ Indicates if the account is frozen. If true, transactions are temporarily disabled
+ for this account. This is particularly useful during key rotations, which require
+ two transactions: rolling over the pending balance to the actual balance and rotating
+ the encryption key. Freezing prevents the user from accepting additional payments
+ between these two transactions.

+ A flag indicating whether the actual balance is normalized. A normalized balance

+ Tracks the maximum number of transactions the user can accept before normalization

+ chunk has a 16-bit limit, the maximum chunk value before normalization would be
+ 2^16 * 2^16 = 2^32. Maintaining this counter is crucial because users must solve

+ Represented as four 16-bit chunks (p0 + 2^16 * p1 + 2^32 * p2 + 2^48 * p3), that can grow up to 32 bits.
+ All payments are accepted into this pending balance, which users must roll over into the actual balance
+ to perform transactions like withdrawals or transfers.
+ This separation helps protect against front-running attacks, where small incoming transfers could force

Subject: [PATCH 33/45] fix(confidential-asset): correct `sub_balances_mut` and
 reject identity-point pubkeys (#330)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# confidential_asset: fix `sub_balances_mut` and reject identity-point
pubkeys

Two hardening fixes in `aptos_experimental::confidential_asset`.

## Fix 1 — `confidential_balance::sub_balances_mut` was performing
addition

The body called `twisted_elgamal::ciphertext_add_assign` instead of
`ciphertext_sub_assign`, so `sub_balances_mut` behaved identically to
`add_balances_mut`. No in-tree caller today, but the function is
`public` and exported; any future caller debiting via `sub_balances_mut`
would silently credit instead.

Deleted `sub_balances_mut` function as it is not used.

## Fix 2 — `ristretto255_twisted_elgamal::new_pubkey_from_bytes`
accepted the identity point

There is no scalar `dk` such that `dk⁻¹ · H = identity`, so an identity
public key does not correspond to any keypair. Accepting it admits two
degenerate states:

- **Registration sigma is forgeable.** The proof `s·H + e·ek == R`
collapses to `s·H == R` when `ek = identity`, so a registrant can pass
`register` without holding any `dk`. The resulting account is
unspendable — anything transferred to it is permanently locked.
- **Auditor channel can be silently disabled.** If `set_asset_auditor`
or `set_chain_auditor` (gated by
`system_addresses::assert_aptos_framework`) is given an identity key,
every subsequent transfer's auditor ciphertext is undecryptable and the
auditor-binding term in the transfer proof becomes degenerate, letting
senders submit auditor amounts unrelated to the actual transfer.

All `CompressedPubkey` values flow through `new_pubkey_from_bytes`
(`register`, `set_asset_auditor`, `set_chain_auditor`,
`deserialize_auditor_eks`), so a single check at the deserializer covers
every entry path.

Changes in `ristretto255_twisted_elgamal.move`:
- `new_pubkey_from_bytes` returns `None` for the identity point in
addition to the existing `None` for non-canonical encodings. The check
is a byte equality against `point_identity_compressed()` (the canonical
encoding of identity is uniquely 32 zero bytes).
- New public helper `is_identity_pubkey(&CompressedPubkey): bool` for
callers that obtain a `CompressedPubkey` through other means and want to
re-validate.

## Tests

New module `tests/confidential_asset/audit_regression_tests.move` — 6
tests:

- `sub_balances_mut_self_yields_zero` — subtracting a balance from
itself decrypts to 0.
- `sub_balances_mut_zero_is_identity` — subtracting an encryption of
zero preserves the amount.
- `new_pubkey_from_bytes_rejects_identity` — 32 zero bytes ⇒ `None`.
- `new_pubkey_from_bytes_accepts_real_key` — generated keypair
round-trips; `is_identity_pubkey` returns `false`.
- `new_pubkey_from_bytes_rejects_non_canonical` — pre-existing rejection
preserved.
- `identity_rejection_composes_with_is_some` — callers using
`assert!(... .is_some())` now reject identity with no caller-side
change.

## Testing:

```
cd aptos-move/framework/aptos-experimental
aptos move test --skip-fetch-latest-git-deps \
    --named-addresses aptos_experimental=0x7 \
    --filter confidential
```

Expected: 64 tests pass (58 existing + 6 new).

## Notes

- No state schema or proof-format changes. Existing accounts and
ciphertexts continue to verify.
- The only other `CompressedPubkey` constructor is
`pubkey_from_secret_key`, which is `#[test_only]`.

From e49d3af7ddf8e5b0b6d3813d22f4b139189ec689 Mon Sep 17 00:00:00 2001
From: Andy Golay

Subject: [PATCH 34/45] feat(confidential assets): add chain auditor and
 auditor epochs (#328)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Two-tier auditor model + epoch tracking for confidential assets

## Summary

The Confidential Asset module previously supported a single optional
per-asset auditor. This PR introduces a **chain-level auditor** (always
required, governed at the framework address) layered alongside the
existing per-asset auditor, plus **monotonic epoch tracking and
append-only history** for both layers. Every confidential transfer now
stamps the active chain and asset auditor epochs onto its `Transferred`
event, enabling reconstruction of which historical key covered which
transfer years after a rotation.

## Behavior changes

### Auditor slot layout

`auditor_eks` (and the matching `auditor_amounts`) now have a fixed
prefix:

```
[0]   chain-level auditor       (always required)
[1]   asset-specific auditor    (required iff get_asset_auditor(token).is_some())
[2..] voluntary auditors        (sender's choice; ordered)
```

Slot identity is bound into the transfer's Fiat–Shamir transcript via
the order of `auditor_eks` (existing mechanism in
`confidential_proof::fiat_shamir_transfer_sigma_proof_challenge`), so a
sender cannot substitute one slot for another.

### Validation

`validate_auditors` now:

- Aborts with new error `ECHAIN_AUDITOR_NOT_SET` if no chain auditor is
configured.
- Rejects the transfer if `auditor_eks[0]` ≠ active chain auditor.
- Rejects the transfer if an asset auditor is set and `auditor_eks[1]` ≠
it.
- Otherwise behaves as before (length checks, ciphertext consistency).

### Epoch + history

`FAController` and `FAConfig` each gain:

- `*_auditor_epoch: u64` — bumped on every set/rotate/clear (including
clears).
- `*_auditor_history: vector` — append-only; each entry
carries `[activated_at_epoch, deactivated_at_epoch)` (`0` while still
active).

`Transferred` event gains `chain_auditor_epoch` and
`asset_auditor_epoch` (`0` when the asset has no auditor).

### Renamed / new module API

| Before | After |
| ----------------------------------- |
------------------------------------------- |
| `set_auditor` | `set_asset_auditor` |
| `get_auditor` | `get_asset_auditor` |
| `AuditorChanged` | `AssetAuditorChanged` (+`new_epoch` field) |
| `FAConfig.auditor_ek` | `FAConfig.asset_auditor_ek` |
| — | `set_chain_auditor` |
| — | `get_chain_auditor` / `*_epoch` / `*_history` |
| — | `get_asset_auditor_epoch` / `*_history` |
| — | `ChainAuditorChanged` |
| — | `AuditorEntry` struct |
| — | `ECHAIN_AUDITOR_NOT_SET` |

### In-flight proof invalidation on rotation

Auditor identity is bound into the proof's Fiat–Shamir transcript, so
rotating either layer invalidates any user transactions signed against
the old key but not yet executed. Documented inline on
`set_chain_auditor` / `set_asset_auditor`.

## Tests

### Move unit tests (`confidential_asset_tests.move`) — 64/64 passing

New coverage:

- `fail_transfer_if_chain_auditor_unset` — abort when chain auditor
missing.
- `fail_transfer_if_slot0_not_chain_auditor` — slot 0 mismatch rejected.
- `fail_transfer_if_asset_auditor_required_but_missing` — slot 1 absent
when required.
- `success_voluntary_auditors_without_asset_auditor` — slot 2+ accepted
with no asset auditor.
- `fail_transfer_after_chain_auditor_rotation` — pre-rotation old-key
proof rejected.
- `success_chain_auditor_rotation_tracks_history` — rotations bump
epochs, history records prior keys, `Transferred` stamps current epoch.

Existing transfer tests updated for the new slot layout (chain auditor
auto-prepended via `get_chain_auditor()` in shared helpers).

### Rust e2e tests (`confidential_asset_e2e.rs`) — 7/7 passing

New coverage:

- `confidential_transfer_rejects_when_chain_auditor_unset`
- `confidential_transfer_rejects_when_slot0_not_chain_auditor`
- `confidential_transfer_rejects_after_chain_auditor_rotation`

`fresh_harness` now installs a default chain auditor; existing tests
pass through unchanged because the test-only
`pack_confidential_transfer_proof_*` helpers auto-prepend the chain
auditor. A `fresh_harness_no_chain_auditor` variant and
`pack_transfer_audited_verbatim` helper support the rejection-path
tests.

> Note: `cargo test -p e2e-move-tests confidential_asset` requires
`RUST_MIN_STACK=33554432` (or higher) — pre-existing requirement,
documented in this module's file header.

## Follow-ups / out of scope

- **Chain-level key custody.** The contract enforces that the
chain-level auditor *exists* and is bound into every transfer, but it
can't enforce *who* holds the private key or *how*. A separate decision
is needed before launch on whether the key sits with a qualified
third-party custodian and whether custody is single-party or
threshold/MPC. Strictly an off-chain operational call.
- **History sizing.** `chain_auditor_history` and
`asset_auditor_history` are unbounded `vector` on
`FAController` / `FAConfig`. Fine pre-launch; if rotation cadence ends
up high in production, follow up with a paginated view or periodic
archival. Not a correctness or compliance gap — just a storage-growth
concern.
- **Per-user auditor epoch tracking on `ConfidentialAssetStore`.** Not
needed in this codebase — auditors only receive ciphertexts at transfer
time, not on the balance, so rollover-staleness (the issue addressed in
zkSecurity finding #01 upstream) does not apply here.
- **Documentation regeneration.**
`aptos-experimental/doc/confidential_asset.md` is left untouched in this
PR; regenerate via `movement move document` against a locally-built
`movement` binary so the markup style stays consistent.

Subject: [PATCH 35/45] [Confidential Asset] Migrate confidential asset code
 from `aptos-experimental` to `aptos-framework` (#366)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Move confidential asset code from `aptos-experimental` to
`aptos-framework`

## Summary

Promotes the Confidential Asset Standard from `aptos-experimental`
(`0x7`) to `aptos-framework` (`0x1`). The module family is no longer
experimental — it now lives alongside the rest of the framework and is
published at the framework address.

## What moved

Source modules (all `0x7::*` → `0x1::*`):

- `confidential_asset` + `.spec.move`
- `confidential_balance` + `.spec.move`
- `confidential_proof` + `.spec.move`
- `ristretto255_twisted_elgamal` + `.spec.move`
- `confidential_gas_e2e_helpers`

Unit tests:

- `confidential_asset_tests.move`
- `confidential_proof_tests.move`
- `ristretto255_twisted_elgamal_tests.move`

Everything under `aptos-experimental/sources/confidential_asset/` and
`aptos-experimental/tests/confidential_asset/` is gone; the equivalents
now live under `aptos-framework/sources/confidential_asset/` and
`aptos-framework/tests/confidential_asset/`.

## Code changes

- Module declarations re-addressed: `module aptos_experimental::*` →
`module aptos_framework::*`.
- All `use aptos_experimental::*` imports inside the module family
rewritten to `use aptos_framework::*`.
- Re-rendered framework reference docs: removed the four `0x7::*`
entries from `aptos-experimental/doc/overview.md` and added the
corresponding `0x1::*` entries to `aptos-framework/doc/overview.md`. The
generated per-module docs (`confidential_asset.md`,
`confidential_balance.md`, `confidential_proof.md`,
`ristretto255_twisted_elgamal.md`) now live under
`aptos-framework/doc/`.
- `aptos_framework_sdk_builder.rs` regenerated with entries for the new
framework entry functions.

## Downstream call-site updates

- `aptos-move/move-examples/confidential_asset/Move.toml` — drop the
`aptos-experimental` dep; all examples already use
`aptos_framework::confidential_asset`.
- `aptos-move/move-examples/confidential_asset/tests/*.move` — rewrite
`use aptos_experimental::*` → `use aptos_framework::*` across the seven
example tests (deposit, normalize, register, rollover, rotate, transfer,
withdraw).
- `scripts/chain-auditor-bootstrap/Move.toml` +
`sources/set_chain_auditor_admin.move` — repoint at the framework
module.

## Rust e2e test update

`aptos-move/e2e-move-tests/src/tests/confidential_asset_e2e.rs` →
`confidential_asset.rs` (registered as `mod confidential_asset;` in
`tests/mod.rs`).

The module-injection harness was retooled to match the new layout:

- Stops compiling `aptos-experimental` and looking for `0x7::*` modules.
- Test-compiles `aptos-framework` and overlays only the
confidential-asset module family (`confidential_asset`,
`confidential_balance`, `confidential_proof`,
`confidential_gas_e2e_helpers`, `ristretto255_twisted_elgamal`) plus
`event`. It deliberately does **not** replace other `0x1` framework
modules — doing so would invalidate state that genesis already published
(account/fungible-store/transaction-validation layouts) and break the
gas-fee prologue.
- `assert_kept_failure` tightened to require `Keep`-with-non-success
instead of "anything that isn't Success" — a fee-discard was previously
masquerading as a kept failure and hiding real bugs.
- Dropped 13 unused helper functions that were carryovers from the
experimental harness.

## Verification

All 14 confidential-asset e2e tests pass against the new layout:

```
RUST_MIN_STACK=67108864 cargo test --release -p e2e-move-tests confidential_asset
...
test result: ok. 14 passed; 0 failed; 0 ignored; 0 measured; 249 filtered out
```

## Breaking changes

Any off-chain caller or downstream Move package referencing the previous
`0x7::confidential_asset` (and friends) must be updated to
`0x1::confidential_asset`. The module functions, struct shapes, and
entry signatures are unchanged.

## Test plan

- [x] `cargo test --release -p e2e-move-tests confidential_asset` —
14/14 pass
- [ ] Re-run framework Move unit tests for the relocated modules
- [ ] Spot-check the move-examples build against the framework dep
- [ ] Verify generated docs render correctly under
`aptos-framework/doc/`

+## Resource `ConfidentialAssetStore`
+
+The confidential_asset module stores a ConfidentialAssetStore object for each user-token pair.
+
+
+
struct ConfidentialAssetStore has key
+

+
+
+
+

+Fields
+
+
+

+

+frozen: bool
+

+

+ Indicates if the account is frozen. If true, transactions are temporarily disabled
+ for this account. This is particularly useful during key rotations, which require
+ two transactions: rolling over the pending balance to the actual balance and rotating
+ the encryption key. Freezing prevents the user from accepting additional payments
+ between these two transactions.
+

+

+normalized: bool
+

+

+ A flag indicating whether the actual balance is normalized. A normalized balance
+ ensures that all chunks fit within the defined 16-bit bounds, preventing overflows.
+

+

+pending_counter: u64
+

+

+ Tracks the maximum number of transactions the user can accept before normalization
+ is required. For example, if the user can accept up to 2^16 transactions and each
+ chunk has a 16-bit limit, the maximum chunk value before normalization would be
+ 2^16 * 2^16 = 2^32. Maintaining this counter is crucial because users must solve
+ a discrete logarithm problem of this size to decrypt their balances.
+

+

+pending_balance: confidential_balance::CompressedConfidentialBalance
+

+

+ Stores the user's pending balance, which is used for accepting incoming payments.
+ Represented as four 16-bit chunks (p0 + 2^16 * p1 + 2^32 * p2 + 2^48 * p3), that can grow up to 32 bits.
+ All payments are accepted into this pending balance, which users must roll over into the actual balance
+ to perform transactions like withdrawals or transfers.
+ This separation helps protect against front-running attacks, where small incoming transfers could force
+ frequent regenerating of zk-proofs.
+

+

+actual_balance: confidential_balance::CompressedConfidentialBalance
+

+

+ Represents the actual user balance, which is available for sending payments.
+ It consists of eight 16-bit chunks (p0 + 2^16 * p1 + ... + 2^112 * p8), supporting a 128-bit balance.
+ Users can decrypt this balance with their decryption keys and by solving a discrete logarithm problem.
+

+

+ek: ristretto255_twisted_elgamal::CompressedPubkey
+

+

+ The encryption key associated with the user's confidential asset account, different for each token.
+

+

+
+
+

+
+
+
+## Resource `GlobalConfig`
+
+Global configuration for confidential assets: primary FA stores, FAConfig derivation, and chain-level auditor state.
+
+
+
struct GlobalConfig has key
+

+
+
+
+

+Fields
+
+
+

+

+allow_list_enabled: bool
+

+

+ Indicates whether the allow list is enabled. If true, only tokens from the allow list can be transferred.
+ This flag is managed by the governance module.
+

+

+extend_ref: object::ExtendRef
+

+

+ Used to derive a signer that owns all the FAs' primary stores and FAConfig objects.
+

+

+chain_auditor_ek: option::Option<ristretto255_twisted_elgamal::CompressedPubkey>
+

+

+ Chain-level auditor encryption key. Required at auditor_eks[0] on every
+ confidential transfer. None until set via [set_chain_auditor]; transfers
+ abort with [ECHAIN_AUDITOR_NOT_SET] in that state.
+

+

+chain_auditor_admin: option::Option<address>
+

+

+ Account authorized to call [set_chain_auditor]. Set by governance via
+ [set_chain_auditor_admin]. None until governance assigns one, during which
+ window set_chain_auditor aborts with [ECHAIN_AUDITOR_ADMIN_NOT_SET].
+

+

+chain_auditor_epoch: u64
+

+

+ Bumped on every [set_chain_auditor] call (including clears). Stamped on each
+ [Transferred] event so off-chain auditors / gateways can identify which
+ historical chain-auditor key was in force at that transfer.
+

+

+
+
+

+
+
+
+## Resource `FAConfig`
+
+Represents the configuration of a token.
+
+
+
struct FAConfig has key
+

+
+
+
+

+Fields
+
+
+

+

+allowed: bool
+

+

+ Indicates whether the token is allowed for confidential transfers.
+ If allow list is disabled, all tokens are allowed.
+ Can be toggled by the governance module. The withdrawals are always allowed.
+

+

+asset_auditor_ek: option::Option<ristretto255_twisted_elgamal::CompressedPubkey>
+

+

+ Per-asset auditor encryption key. When set, required at auditor_eks[1] on
+ every transfer of this asset (additive to the chain auditor at [0]). Set via
+ [set_asset_auditor] by the FA metadata object's root owner.
+

+

+asset_auditor_epoch: u64
+

+

+ Bumped on every [set_asset_auditor] call (including clears). Stamped on each
+ [Transferred] event for this asset so off-chain auditors / gateways can
+ identify which historical asset-auditor key was in force at that transfer.
+

+

+

+
+
+

+
+
+
+## Struct `Transferred`
+
+Emitted after a successful confidential_transfer between two registered confidential accounts.
+
+This is the primary on-chain signal for indexers and tooling: **plaintext amounts are not** included;
+fields carry **compressed Twisted-ElGamal ciphertexts** and a **subset of sigma commitment bytes** copied
+from the verified proof. See the technical whitepaper (whitepaper.md, §5) for a field-by-field guide.
+
+
+
#[event]
+struct Transferred has drop, store
+

+
+
+
+

+Fields
+
+
+

+

+from: address
+

+

+ Address of the sender's confidential account (the signer of the transfer entry).
+

+

+to: address
+

+

+ Recipient confidential account address.
+

+

+asset_type: address
+

+amount: confidential_balance::CompressedConfidentialBalance
+

+

+ Encrypted transfer amount under the recipient key (pending-balance / four-chunk layout).
+

+

+ek_volun_auds: vector<u8>
+

+

+ Flattened **transfer sigma x7s** commitments taken from the verified TransferProof: for each
+ auditor encryption key row in the proof, exactly **four** compressed Ristretto points (32 bytes each),
+ concatenated in **row-major** order (auditor index, then inner index 0..3). Empty when the proof carries
+ **no** auditor rows. Total byte length is always **128 × n** with n = number of auditor rows
+ (confidential_proof::auditors_count_in_transfer_proof / proof.sigma_proof.xs.x7s.length()).
+

+

+

+chain_auditor_epoch: u64
+

+

+ Value of [GlobalConfig.chain_auditor_epoch] at the time of the transfer.
+ Required for compliance: lets future audits identify which historical
+ chain-level auditor key was in force, so that the transcript can still be
+ decrypted years after a key rotation.
+

+

+asset_auditor_epoch: u64
+

+

+ Value of [FAConfig.asset_auditor_epoch] for this asset at the time of the
+ transfer. 0 only when [set_asset_auditor] has never been called for this
+ asset; once called (including a clear with empty bytes) the epoch is bumped
+ and stamped here even if the current asset_auditor_ek is None. Off-chain
+ auditors / gateways resolve (asset_type, asset_auditor_epoch) to the active
+ key by indexing [AssetAuditorChanged] events.
+

+

+Validates the auditor-related fields of a confidential transfer.

+
+Returns false (rejecting the transfer) if any of:
+- any auditor_amount does not encrypt the same plaintext as transfer_amount;
+- the lengths of auditor_eks, auditor_amounts, and the transfer-proof auditor
+row count disagree;
+- auditor_eks is missing the required prefix (see slot layout below);
+- the prefix slot keys do not equal the active chain / asset auditor keys.
+

+[2..] voluntary auditors        (sender's choice, ordered)
+```
+Auditor identity at slots 0 and 1 is bound into the transfer's Fiat–Shamir
+transcript (via the order in which auditor_eks is hashed in
+confidential_proof::fiat_shamir_transfer_sigma_proof_challenge), so a sender
+cannot substitute one auditor's slot for another's.

+# Module `0x1::confidential_balance`
+
+This module implements a Confidential Balance abstraction, built on top of Twisted ElGamal encryption,
+over the Ristretto255 curve.
+
+The Confidential Balance encapsulates encrypted representations of a balance, split into chunks and stored as pairs of
+ciphertext components (C_i, D_i) under basepoints G and H and an encryption key P = dk^(-1) * H, where dk
+is the corresponding decryption key. Each pair represents an encrypted value a_i - the i-th 16-bit portion of
+the total encrypted amount - and its associated randomness r_i, such that C_i = a_i * G + r_i * H and D_i = r_i * P.
+
+The module supports two types of balances:
+- Pending balances are represented by four ciphertext pairs (C_i, D_i), i = 1..4, suitable for 64-bit values.
+- Actual balances are represented by eight ciphertext pairs (C_i, D_i), i = 1..8, capable of handling 128-bit values.
+
+This implementation leverages the homomorphic properties of Twisted ElGamal encryption to allow arithmetic operations
+directly on encrypted data.

+# Module `0x1::ristretto255_twisted_elgamal`
+
+This module implements a Twisted ElGamal encryption API, over the Ristretto255 curve, designed to work with
+additional cryptographic constructs such as Bulletproofs.
+
+A Twisted ElGamal *ciphertext* encrypts a value v under a basepoint G and a secondary point H,
+alongside a public key Y = sk^(-1) * H, where sk is the corresponding secret key. The ciphertext is of the form:
+(v * G + r * H, r * Y), where r is a random scalar.
+
+The Twisted ElGamal scheme differs from standard ElGamal by introducing a secondary point H to enhance
+flexibility and functionality in cryptographic protocols. This design still maintains the homomorphic property:
+Enc_Y(v, r) + Enc_Y(v', r') = Enc_Y(v + v', r + r'), where v, v' are plaintexts, Y is the public key,
+and r, r' are random scalars.

+Identity-point public keys are rejected because they break both privacy and
+soundness: ciphertexts encrypted under ek = identity have the form
+(v*G + r*H, r*identity) = (v*G + r*H, identity), so the randomness blinding
+is null and any observer can brute-force the encrypted value. Sigma protocols
+that bind the public key (registration, transfer, rotation) also become
+trivially forgeable: the prover does not need to know any secret key, since
+e * identity = identity for any challenge e.

-## Resource `ConfidentialAssetStore`
-
-The confidential_asset module stores a ConfidentialAssetStore object for each user-token pair.
-
-
-
struct ConfidentialAssetStore has key
-

-
-
-
-

-Fields
-
-
-

-

-frozen: bool
-

-

- Indicates if the account is frozen. If true, transactions are temporarily disabled
- for this account. This is particularly useful during key rotations, which require
- two transactions: rolling over the pending balance to the actual balance and rotating
- the encryption key. Freezing prevents the user from accepting additional payments
- between these two transactions.
-

-

-normalized: bool
-

-

- A flag indicating whether the actual balance is normalized. A normalized balance
- ensures that all chunks fit within the defined 16-bit bounds, preventing overflows.
-

-

-pending_counter: u64
-

-

- Tracks the maximum number of transactions the user can accept before normalization
- is required. For example, if the user can accept up to 2^16 transactions and each
- chunk has a 16-bit limit, the maximum chunk value before normalization would be
- 2^16 * 2^16 = 2^32. Maintaining this counter is crucial because users must solve
- a discrete logarithm problem of this size to decrypt their balances.
-

-

-pending_balance: confidential_balance::CompressedConfidentialBalance
-

-

- Stores the user's pending balance, which is used for accepting incoming payments.
- Represented as four 16-bit chunks (p0 + 2^16 * p1 + 2^32 * p2 + 2^48 * p3), that can grow up to 32 bits.
- All payments are accepted into this pending balance, which users must roll over into the actual balance
- to perform transactions like withdrawals or transfers.
- This separation helps protect against front-running attacks, where small incoming transfers could force
- frequent regenerating of zk-proofs.
-

-

-actual_balance: confidential_balance::CompressedConfidentialBalance
-

-

- Represents the actual user balance, which is available for sending payments.
- It consists of eight 16-bit chunks (p0 + 2^16 * p1 + ... + 2^112 * p8), supporting a 128-bit balance.
- Users can decrypt this balance with their decryption keys and by solving a discrete logarithm problem.
-

-

-ek: ristretto255_twisted_elgamal::CompressedPubkey
-

-

- The encryption key associated with the user's confidential asset account, different for each token.
-

-

-
-
-

-
-
-
-## Resource `GlobalConfig`
-
-Global configuration for confidential assets: primary FA stores, FAConfig derivation, and chain-level auditor state.
-
-
-
struct GlobalConfig has key
-

-
-
-
-

-Fields
-
-
-

-

-allow_list_enabled: bool
-

-

- Indicates whether the allow list is enabled. If true, only tokens from the allow list can be transferred.
- This flag is managed by the governance module.
-

-

-extend_ref: object::ExtendRef
-

-

- Used to derive a signer that owns all the FAs' primary stores and FAConfig objects.
-

-

-chain_auditor_ek: option::Option<ristretto255_twisted_elgamal::CompressedPubkey>
-

-

- Chain-level auditor encryption key. Required at auditor_eks[0] on every
- confidential transfer. None until set via [set_chain_auditor]; transfers
- abort with [ECHAIN_AUDITOR_NOT_SET] in that state.
-

-

-chain_auditor_admin: option::Option<address>
-

-

- Account authorized to call [set_chain_auditor]. Set by governance via
- [set_chain_auditor_admin]. None until governance assigns one, during which
- window set_chain_auditor aborts with [ECHAIN_AUDITOR_ADMIN_NOT_SET].
-

-

-chain_auditor_epoch: u64
-

-

- Bumped on every [set_chain_auditor] call (including clears). Stamped on each
- [Transferred] event so off-chain auditors / gateways can identify which
- historical chain-auditor key was in force at that transfer.
-

-

-
-
-

-
-
-
-## Resource `FAConfig`
-
-Represents the configuration of a token.
-
-
-
struct FAConfig has key
-

-
-
-
-

-Fields
-
-
-

-

-allowed: bool
-

-

- Indicates whether the token is allowed for confidential transfers.
- If allow list is disabled, all tokens are allowed.
- Can be toggled by the governance module. The withdrawals are always allowed.
-

-

-asset_auditor_ek: option::Option<ristretto255_twisted_elgamal::CompressedPubkey>
-

-

- Per-asset auditor encryption key. When set, required at auditor_eks[1] on
- every transfer of this asset (additive to the chain auditor at [0]). Set via
- [set_asset_auditor] by the FA metadata object's root owner.
-

-

-asset_auditor_epoch: u64
-

-

- Bumped on every [set_asset_auditor] call (including clears). Stamped on each
- [Transferred] event for this asset so off-chain auditors / gateways can
- identify which historical asset-auditor key was in force at that transfer.
-

-
-
#[event]

-

-

-chain_auditor_epoch: u64
-

-

- Value of [GlobalConfig.chain_auditor_epoch] at the time of the transfer.
- Required for compliance: lets future audits identify which historical
- chain-level auditor key was in force, so that the transcript can still be
- decrypted years after a key rotation.
-

-

-asset_auditor_epoch: u64
-

-

- Value of [FAConfig.asset_auditor_epoch] for this asset at the time of the
- transfer. 0 only when [set_asset_auditor] has never been called for this

- and stamped here even if the current asset_auditor_ek is None. Off-chain
- auditors / gateways resolve (asset_type, asset_auditor_epoch) to the active
- key by indexing [AssetAuditorChanged] events.

-- the lengths of auditor_eks, auditor_amounts, and the transfer-proof auditor
-row count disagree;
-- auditor_eks is missing the required prefix (see slot layout below);

-Auditor identity at slots 0 and 1 is bound into the transfer's Fiat–Shamir
-transcript (via the order in which auditor_eks is hashed in
-confidential_proof::fiat_shamir_transfer_sigma_proof_challenge), so a sender
-cannot substitute one auditor's slot for another's.

-# Module `0x7::confidential_balance`
-
-This module implements a Confidential Balance abstraction, built on top of Twisted ElGamal encryption,
-over the Ristretto255 curve.
-
-The Confidential Balance encapsulates encrypted representations of a balance, split into chunks and stored as pairs of
-ciphertext components (C_i, D_i) under basepoints G and H and an encryption key P = dk^(-1) * H, where dk
-is the corresponding decryption key. Each pair represents an encrypted value a_i - the i-th 16-bit portion of
-the total encrypted amount - and its associated randomness r_i, such that C_i = a_i * G + r_i * H and D_i = r_i * P.
-
-The module supports two types of balances:
-- Pending balances are represented by four ciphertext pairs (C_i, D_i), i = 1..4, suitable for 64-bit values.
-- Actual balances are represented by eight ciphertext pairs (C_i, D_i), i = 1..8, capable of handling 128-bit values.
-
-This implementation leverages the homomorphic properties of Twisted ElGamal encryption to allow arithmetic operations
-directly on encrypted data.

-Returns n, the number of **auditor rows** encoded in the transfer sigma proof — i.e.
-proof.sigma_proof.xs.x7s.length(). Each row holds the four x7s curve commitments for one auditor EK.
-confidential_asset uses this to cross-check auditor ciphertext vectors on confidential_transfer.

-# Module `0x7::ristretto255_twisted_elgamal`
-
-This module implements a Twisted ElGamal encryption API, over the Ristretto255 curve, designed to work with
-additional cryptographic constructs such as Bulletproofs.
-
-A Twisted ElGamal *ciphertext* encrypts a value v under a basepoint G and a secondary point H,
-alongside a public key Y = sk^(-1) * H, where sk is the corresponding secret key. The ciphertext is of the form:
-(v * G + r * H, r * Y), where r is a random scalar.
-
-The Twisted ElGamal scheme differs from standard ElGamal by introducing a secondary point H to enhance
-flexibility and functionality in cryptographic protocols. This design still maintains the homomorphic property:
-Enc_Y(v, r) + Enc_Y(v', r') = Enc_Y(v + v', r + r'), where v, v' are plaintexts, Y is the public key,
-and r, r' are random scalars.

-
-Creates a new public key from a serialized Ristretto255 point.
-Returns Some(CompressedPubkey) if the deserialization is successful and the
-resulting point is non-identity, otherwise None.
-
-Identity-point public keys are rejected because they break both privacy and
-soundness: ciphertexts encrypted under ek = identity have the form
-(v*G + r*H, r*identity) = (v*G + r*H, identity), so the randomness blinding
-is null and any observer can brute-force the encrypted value. Sigma protocols
-that bind the public key (registration, transfer, rotation) also become
-trivially forgeable: the prover does not need to know any secret key, since
-e * identity = identity for any challenge e.
