the minimum required access, preferably contents: read for checkout (or
permissions: {} if checkout is tokenless). Keep the existing cargo test command
unchanged.
In `@ios/Cove/Flows/TapSignerFlow/TapSignerImportRetryView.swift`:
- Around line 50-55: Update the retry failure handling in
TapSignerImportRetryView so it checks error.isAuthError() first and presents the
wrong-PIN alert for authentication errors, matching TapSignerEnterPinView;
retain .tapSignerDeriveFailed with the existing generic message for all other

In `@ios/Cove/Flows/TapSignerFlow/TapSignerSetupRetryView.swift`:
- Around line 47-58: Update the incomplete-response branch in
TapSignerSetupRetryView to use the same “TapSigner setup failed. Please try
again.” message as the existing failure branch, while preserving the current
alert and sheet-state handling.
In `@rust/src/backup/import.rs`:
- Around line 356-374: Make the wallet metadata rollback in the surrounding
import/rollback method atomic for each (Network, WalletMode) pair: serialize the
get_all and save_all_wallets operations using the existing scope lock, or
replace them with a transactional read-modify-write API. Ensure concurrent
restores cannot commit changes between the read and save, while preserving the
current removal of self.metadata.id and failure reporting.
In `@rust/src/database/wallet_data.rs`:
- Around line 395-401: Update wallet_data_artifacts_exist to treat read_dir
failures as occupied unless the error is specifically NotFound; only return
false for a confirmed empty or absent wallet-data directory, while preserving
the existing true result for files and non-empty directories.
In `@rust/src/fee_client.rs`:
- Around line 35-36: Update ValidatedFeeResponse::try_from and the fee-tier
handling around FeeRateOptions so remote rates above MAX_REMOTE_FEE_RATE are
clamped to the ceiling instead of causing validation to fail. Preserve rejection
for invalid or absurd values outside the intended validation rules, and ensure
fees() and get_and_update_base_fee_rate_options still produce fee options during
high-fee spikes.
- Around line 471-482: Update
persisted_snapshot_keeps_wall_clock_age_for_refresh_limits to account for hosts
whose monotonic uptime is under 120 seconds: assert either that
last_fetched.elapsed() is at least 30 seconds or that
Instant::now().checked_sub(...) was unavailable, rather than requiring the
elapsed-time assertion unconditionally. Preserve validation of the fallback
behavior in CachedFeeResponse::from_persisted_snapshot.
In `@rust/src/manager/wallet_manager.rs`:
- Around line 1296-1303: Update the expect message on WalletActor::new_with_db
in the preview-wallet setup to describe actor construction failure rather than
in-memory wallet data database opening; leave the earlier database-opening error
message unchanged.
In `@rust/src/seed_qr.rs`:
- Around line 118-120: Update the validation around qr in the seed QR parsing
flow to avoid usize::is_multiple_of, or declare Rust 1.87.0 as the workspace’s
minimum supported version and pin CI/toolchain configuration accordingly.
Preserve the existing InvalidLength error behavior for lengths not divisible by
four.
In `@rust/src/wallet/addressing.rs`:
- Around line 37-42: Replace the standalone map_err closures around
BdkStore::delete_sqlite_store in rust/src/wallet/addressing.rs lines 37-42 and
79-84 with map_err_prefix("failed to delete wallet filestore",
WalletError::PersistError), using cove_util::ResultExt. Apply the same change at
both sites.

- Around line 257-259: Update the transactions() mapping flow to batch-load
labels using shared redb read transactions before constructing the transaction
list. Reuse the batched label data when creating each Transaction, replacing
per-item Transaction::new_with_labels calls; leave transaction_for_tx_id
unchanged.
In `@rust/src/manager/wallet_manager/actor/transactions.rs`:
- Around line 72-75: Compute automatic_spend_policy once in
fee_rate_options_with_total_fee before constructing the fast, medium, and slow
options, then pass a reference to that policy into each
fee_option_with_total_fee call. Update fee_option_with_total_fee to accept and
use the provided policy instead of invoking self.automatic_spend_policy
internally, preserving the existing transaction-building behavior.

runCatchingCancellablelogs the full throwable and stack trace (Log.kt:51). TapSigner exceptions can carry low-level transport/FFI payloads, so this newly reintroduces the diagnostic logging that the surrounding changes remove. Use a cancellation-preserving result helper that logs only the fixed operation message, without attaching the throwable.

- A bad PIN is now treated as a generic import failure. This screen retries with
manager.enteredPin, so dismissing the alert only lets the user submit the same wrong PIN again; unlike the iOS path, there is no route to re-enter it. Preserve the auth-error branch and open the existing wrong-PIN flow.

- This read/modify/write can lose a concurrent metadata update. While
mark_wallet_as_verifiedperforms database I/O, another operation can update the cached name/type; line 127 then replaces that newer value with this stale clone. After persistence succeeds, mutate onlyverifiedunder the write lock and clone the latest metadata for reconciliation.

- Around line 140-151: Move the NFC cleanup assignments after the
runCatchingCancellable call into a finally block surrounding the
nfc.continueSetup(response) operation, so cancellation also resets
manager.isScanning, manager.isTagDetected, and both nfcManager callbacks.

Use reviewed revisions for git dependencies and OpenSSL 3.6.3. Require the lockfile in CI, local checks, and mobile binding builds so dependency resolution cannot move without review.
Reserve wallet identifiers before restore writes and remove only artifacts created by a failed attempt. Keep preview wallets in memory so test keys cannot enter production storage.
Reject HTTP errors and invalid or excessive fee rates before they reach transaction builders. Persist fetch times so offline fallback data expires after one hour across restarts.
Apply one spend policy to automatic transaction and fee builders. Keep unconfirmed external outputs and locked outputs out of automatic selection while allowing unconfirmed internal change.
Require exact four-digit ASCII groups before parsing word indexes. Reject truncated and Unicode input as typed errors instead of allowing a panic.
Store validated PINs in zeroizing typed values and redact their debug output. Remove PIN, command, APDU, and raw error details from mobile logs and alerts.
Sync the Android and iOS bindings with the restore, preview wallet, SeedQR, and TapSigner error API changes.
Serialize wallet metadata updates in one redb transaction so a failed restore cannot remove a wallet that another operation added. Keep the restore reservation alive through cleanup, preserve existing artifacts, and treat unreadable wallet data paths as occupied.
Read preview transaction labels from the actor-owned in-memory database instead of opening persistent wallet storage. Batch label reads for transaction lists and calculate the spend policy once per fee-options request to avoid repeated database work.
Accept plausible remote fee responses and cap automatic transaction fees at 500 sat/vB so the send flow stays available during fee spikes. Track persisted cache age with wall-clock time, normalize cached values, and log invalid fee responses instead of silently dropping them.
Show the wrong-PIN recovery path after an iOS import retry and use consistent setup failure copy. Use cancellation-safe Android retry handling and remove redundant broad exception wrappers so detekt can verify the NFC flow.
Grant the workflow token read-only repository content access so jobs do not inherit broader default permissions.
Build wallet storage errors with the shared result helper to keep context handling consistent and preserve the original failure text.
