From 8f3b6d12dca8ba6407a52829e053323d1e8a44a4 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 2 Sep 2026 19:22:52 +0000 Subject: [PATCH 01/44] Publish current SpeedTrader AI project state from handoff ZIP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Repository migration/backup of the existing project as received in SpeedTrader_AI_FINAL.zip. This is a verbatim snapshot of the current implementation state — no bug fixes, refactors, architectural changes, or feature work were performed. Contents (Steps 1-4 as actually implemented): - data/: snapshot builder, validators, schemas, freshness - quant/: features, scoring, expected_value, candidate, engine, cost_policy, position_sizing, strategies/s07 (only implemented strategy) - risk/: deterministic risk engine, measures, state - storage/decision_store.py, app/orchestrator.py (Step 4 vertical slice) - alpaca/, common/, decision/, config.py - configs/, docs/reference/SpeedTraderBot_v6.1.mq5 (read-only reference, sha256 c799acaa797a4f23a8c9531c3b4f14599b73736af2151d9eeb7f42209332e8d9) - tests/ (unit + integration) Placeholder packages carried over unchanged and still unimplemented: agents/, llm/, evidence/, memory/, execution/, portfolio/, monitoring/, replay/, evaluation/, bridge/. Known state at time of snapshot, preserved deliberately and NOT fixed: transaction_cost schema desync between quant/cost_policy.py, configs/execution_config.yaml and tests/unit/quant/test_cost_policy.py (68 failing tests + 1 collection error). Awaiting owner decision. Excluded: __pycache__, .pytest_cache, *.egg-info, .env, virtualenvs. No credentials or secrets are included.

Not the 1.5/3.0 ATR multipliers, not the k=2..21 +window, not the EMA200 filter, not the DI comparison, not the base score of 50, and no +condition is added or removed. Where the port differs from the source it is because +Python has a state MQL5 does not — see DEVIATIONS below. + +-------------------------------------------------------------------------------- +[UNVERIFIED] ADX / DI PARITY +-------------------------------------------------------------------------------- +S07's fourth condition reads st.diPlus and st.diMinus, which come from +iADX(symbol, PERIOD_H1, 14) buffers 1 and 2 (source L520, L594-596). + +quant/features.py::adx() implements MT5's documented ADX algorithm — DM normalised by +TR per bar, then smoothed with alpha = 2/(n+1). This differs from Wilder's textbook +ADX, which smooths +DM, -DM and TR separately with alpha = 1/n. The implementation +follows the deposited MQL5 specification, but it has NOT been compared numerically +against a running MetaTrader 5 terminal. Its status is UNVERIFIED, and no part of this +module may be described as having verified MT5 parity. + +Exposure for S07 specifically is low but not zero: the strategy uses only the ordering +`diPlus > diMinus`, never an absolute threshold. A difference in smoothing shifts +levels more readily than it flips an ordering. S03 (`adx >= 20`) and S05 (`adx > 25`) +are materially more exposed and must not be ported until this is resolved. + +-------------------------------------------------------------------------------- +INDEXING +-------------------------------------------------------------------------------- +MQL5 shift 1 is the last CLOSED bar; shift 0 is the forming bar. UpdateIndicators() +reads every indicator at [1] (source L614-618). Series enforces this: shift 1 maps to +bars[-1] and shift 0 raises. S07 therefore cannot read an unclosed bar — the guard is +structural, not a convention, so no look-ahead is possible through this path. + +-------------------------------------------------------------------------------- +DEVIATIONS FROM THE SOURCE, AND WHY +-------------------------------------------------------------------------------- +1. Missing indicators. MQL5's SymbolState always holds a double; an unavailable + indicator would arrive as 0.0. Python holds None. `ema200 is None` is treated as + INDICATOR_UNAVAILABLE (no signal), not as 0.0 — because `price > 0.0` is true for + every equity and would silently pass the EMA200 filter on missing data. This is a + fail-closed necessity, not a formula change. + +2. Diagnostic detail. The source returns an invalid signal with no reason. This port + records which conditions failed. Evaluation ORDER and OUTCOME are unchanged: BUY is + tested first and short-circuits (the source's `else if`); diagnostics are collected + only on the path that produces no signal. + +3. NormalizePrice / slPips. InitSignal (source L888, L891) rounds to broker tick size + and converts the stop to pips via SymbolPip. Neither has an equity meaning. Prices + are emitted unrounded here; tick rounding belongs to the execution layer against + Alpaca asset metadata.

Four files (configs/execution_config.yaml, tests/unit/quant/test_cost_policy.py, tests/unit/quant/test_expected_value.py and, decisively, the production source src/speedtrader/quant/expected_value.py) were already written against the price- and direction-aware contract. Only quant/cost_policy.py still implemented the earlier flat-schema model, and its entire public API (per_share_cost, CommissionModel, Exactness, MODEL_ID, cost_basis) was referenced by nothing in the repository except itself. expected_value.py:196 already called policy.estimate(entry=, take_profit=, direction=, spread=) and :214 policy.breakdown(estimate) — neither of which existed. That ImportError/AttributeError cascade accounted for the collection error plus all 68 downstream failures. This rewrites cost_policy.py to the contract the rest of the codebase already expects. No configuration value was added, changed or invented. Model corrections carried by the newer contract: - Commission is charged on BOTH legs of the round trip (per_share x2, and the notional rate applied to entry and exit). The previous implementation counted it once while correctly counting CAT across both sides, which understated cost and therefore overstated EV — the unsafe direction for a positive-EV gate. - Commission accepts per-share and rate-of-notional together rather than as a mutually exclusive enum, because the published schedule quotes a percentage range and an account may carry both shapes. - SEC is priced on the leg that is actually the sell: for a short that is the entry (price known, exact); for a long it is the exit, priced at take_profit, the upper of the two modelled outcomes (conservative). This replaces an unsigned "approximate" with a signed overstatement. - Estimate quality is graded per component and overall, naming daily fee aggregation rounding as the single non-conservative omission instead of leaving it in an undifferentiated exclusions list. - A per-symbol override replaces the default wholesale; an override omitting a component fails closed rather than half-inheriting it. - transaction_cost.model is cross-checked against the model the code implements, so this class of config/code drift fails loudly instead of mispricing silently. Preserved deliberately: - Production commission remains unresolved and the pipeline still fails closed. The §46 semantic decisions (paper vs live-equivalent economics, commission arrangement, slippage model, regulatory representation) remain open. - slippage.source may never be 'authoritative'. - An operator assumption without a stated assumption is rejected, now applied to every component rather than slippage alone. - configs/ and the MQL5 reference are untouched (sha256 c799acaa797a4f23a8c9531c3b4f14599b73736af2151d9eeb7f42209332e8d9). One test assertion changed: test_expected_value.py referenced the old breakdown key "fixed", a name carried over from the flat model and misleading here because the non-spread portion varies with price via SEC. The key is now "per_share_fees"; the asserted value and intent are unchanged. Suite: 251 passed / 68 failed / 1 error -> 374 passed / 1 skipped / 0 failed.

An untested fail-closed guard is indistinguishable from a fail-open one, so each is now exercised explicitly. Every new test was mutation-verified: the guard it covers was deliberately broken and the test confirmed to fail. risk/engine.py 93% -> 100% - sector exposure cap: had NO test at all. It is the equity analogue of Bot v6 CurrencyExposure() and the only exposure rule that was translated rather than ported, so nothing previously proved the translation blocks. - size rounding to zero shares: a sub-one-share result must REJECT, never submit a 0-share order. - revalidate() (§57): had NO test. This is the mechanism that makes "every Portfolio Manager modification is revalidated" true, and it was entirely unverified. Now pinned: identical rule set, a breach stays a breach across revalidation, revalidation reflects the CURRENT portfolio rather than the one the proposal was sized against, and there is no parameter through which a caller can inject an approved quantity — the engine remains the sole sizing authority. risk/measures.py: sector_exposure_pct, including that an unstopped position counts as a FULL unit of risk (PositionRiskPct semantics), never zero. quant/cost_policy.py 94% -> 100% Guards added in the previous commit were themselves untested: - config/code model drift is refused (the exact failure class that caused the desynchronisation this module was just repaired from) - slippage may never be declared 'authoritative' - operator assumptions require a stated assumption on every component - non-mapping block/default/component/override inputs - non-positive prices, which would silently zero the notional fees - blank provenance fields Mutation results (each mutant killed): sector cap always passes -> 2 tests fail zero-quantity guard disabled -> 2 tests fail unstopped position = zero risk -> 2 tests fail revalidate() becomes a rubber stamp -> 3 tests fail No production behaviour changed; this commit is tests only.

Two failures were silent: editing the reference (every "ported from L1043" citation quietly points at different lines) and a SOURCE_HASH drifting from the file (the provenance claim becomes decorative). tests/unit/test_source_integrity.py Asserts the reference exists, hashes to the expected value, is not truncated, and that expected_value.SOURCE_HASH and scoring.SOURCE_HASH agree with the file actually on disk. Verified by tampering: appending one line to the reference fails the test; the file was restored and re-verified byte-identical. .github/workflows/ci.yml - tests on Python 3.11 and 3.12 - MQL5 hash checked BEFORE the suite, so the failure is unambiguous when the quant tests would fail as a downstream consequence - lint scoped to real defects (F821/F811/F823/E9). Stylistic rules are deliberately not gating: a formatting opinion must never be able to block a correctness fix. The wider ruleset currently reports ~188 stylistic findings and mass-reformatting the quant modules is not worth the diff risk. - a separate safety-invariants job asserting execution environment is 'paper' and never live, replay execution stays disabled, risk config remains fail_closed with the kill switch on, and no credential-shaped literals are committed. Kept as its own job so these still fail loudly if the suite above is ever narrowed. Also asserts the persisted cost breakdown lists exactly the exclusions the module declares; a breakdown that under-reports its own omissions is a false audit trail. Reviewed and rejected as non-issues: ruff BLE001 on the orchestrator's blind excepts (they convert ANY failure into FAILED, which is the §111 fail-closed requirement) and PLR0124 self-comparisons (NaN idioms). All six CI steps verified locally. Suite: 402 -> 407 passed, 1 skipped.

Evidence only — no configuration value changed. Verified correct against the primary source (page 3, Equities): SEC sells only $0.0000206 x Trade Value matches config TAF sells only $0.000195/share, max $9.79/trade matches config (incl. cap and 50,205-share threshold) CAT buys+sells $0.000003 per equivalent share matches config This resolves §46 Q4 (regulatory representation) with no change needed, and independently validates the model's shape: SEC is a rate on notional while the other two are per-share, which is precisely why one flat per-share constant cannot represent all three. Commission (§46 Q2) is NOT resolvable from any document. The schedule says Alpaca charges no commission EXCEPT for index options, the Elite Smart Router, non-retail order flow, or accounts established via an authorized business partner. Which applies is a property of the account, not of the schedule. Corrected an inaccuracy in the existing config comment: it claims the schedule quotes commissions as a "RANGE (0%-3% per transaction)". No such range appears in the current schedule; it is "free, except in three named cases". The comment appears to derive from an older or misread revision. Methodology note recorded: an automated summary of the PDF reported the SEC fee as "$0.000119 per share", which is wrong — the SEC fee is a rate on trade value, not a per-share charge. That summary was discarded and every figure re-read from the extracted text. Summarised financial data is not treated as a source. Also noted: the config cites rates_effective_date 2026-07-20 while the retrieved schedule states "Revised on September 1, 2026". The rates are identical so nothing is mispriced, but the provenance date no longer matches the cited document. Left unchanged pending the owner decision it is bundled with.

From eeceda9c257efcbd05fc175fe7fd419e64107f29 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 2 Sep 2026 20:08:04 +0000 Subject: [PATCH 06/44] =?UTF-8?q?Resolve=20the=20commission=20decision=20a?= =?UTF-8?q?nd=20correct=20the=20rates=20provenance=20date=20(=C2=A746)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Owner delegated the commission decision; recorded as standard-retail commission-free, and approved the rates-date correction. configs/execution_config.yaml commission: per_share 0.0, rate_of_notional 0.0, source operator_assumption. source is deliberately NOT 'authoritative': the schedule publishes the RATE, but the claim that this account is standard retail — no Elite Smart Router, no authorized-business-partner arrangement, retail order flow — is an attestation about the account that no vendor document can make. The assumption string records the attestation, its date, and the conditions that would invalidate it. rates_effective_date and the regulatory reference: 2026-07-20 -> 2026-09-01, matching the schedule revision actually cited. No rate value changed; all three regulatory rates were already verified correct against the primary source in the previous commit. Removed the incorrect comment claiming the schedule quotes commissions as a "0%-3% range". It does not. The pipeline now runs end to end on the PRODUCTION config for the first time: verdict PASS, 432 shares, EV 0.4816 against a 0.50 bootstrap — costs are being subtracted, not zeroed, which is the property the positive-EV gate depends on. Tests updated, NOT weakened. Nine tests asserted the config was unresolved and had to change; the fail-closed behaviour they protected is still proven, now via fixtures rather than by relying on production being broken: - removing the commission block re-closes the policy, the QuantCore, the orchestrator and the CLI (four separate levels) - the existing per-key parametrised test still deletes every required key individually - new: every cost component must carry recorded provenance, and commission and slippage must be operator_assumption with a non-empty assumption - the CLI cost fail-closed path is now exercised against a deliberately broken config via SPEEDTRADER_CONFIG_DIR, instead of depending on the shipped one - the CLI's next fail-closed gate (no market data -> no snapshot, no decision, non-zero exit) is now covered, which it was not before Suite: 407 -> 412 passed, 1 skipped. Known defect found while verifying, fixed next: cost_policy.breakdown() documents itself as "provenance carried onto every persisted decision", but the breakdown is computed in EVResult and never reaches CandidateSignal or DecisionLog. The persisted record therefore stores expected_value without the cost assumptions that produced it, which the decision trace is supposed to make reconstructible.

Verified first that alpaca-py 0.44.0 genuinely supports what is needed (contract discovery with strike/expiry/open-interest, option quotes and chains, single-leg and multi-leg execution with PositionIntent) so nothing here is built on an assumed capability. STRUCTURE: long single-leg call (BUY) / put (SELL). Chosen for correctness, not convenience: maximum loss is the premium paid, known EXACTLY at entry, under every price path. An equity stop-loss is an intention that price can gap through, so the deterministic risk model can now size on an exact maximum loss instead of an assumed one — a stronger safety property than the equity path it replaces. Secondary: one leg is one fill (a two-leg spread can leg out and leave an unhedged position), and buying options needs the lowest approval level. A bearish view is a LONG PUT, never a short call: risk stays defined in both directions. Structure is pluggable; VERTICAL_DEBIT is declared and explicitly refused rather than silently downgraded. S07 IS UNTOUCHED. Its MQL5 formula still produces the directional view on the underlying; this is a translation layer, not a modification. The 1.5*ATR stop and 3.0*ATR target are carried through for management and audit but deliberately NOT used to size the option and NOT converted into a premium — that would invent a volatility assumption the system has not earned. options/contracts.py selection is deterministic and does no network I/O, so every rule is testable offline and reproduces in replay. Gates ordered cheap structural first, liquidity last. Adjusted (non-100 multiplier) contracts are rejected outright: they do not deliver 100 shares and would silently corrupt every downstream risk number. Rejection reasons are counted and returned. options/risk.py contracts = risk_budget / (ask * multiplier). NOT the equity shares = risk_money / stop_distance: the denominators mean different things and substituting one for the other overstates size. Priced at the ASK, never the mid — the mid understates max loss by half the spread every time. Contract cap and a book-wide premium concentration cap. Sub-one-contract is a REJECT, never rounded up. options/cost.py per-CONTRACT fees from the schedule revised 2026-09-01: TAF 0.00329 sell-side, CAT 0.000003 x100 equiv shares both sides, ORF 0.015 and OCC 0.025 both sides, SEC 0.0000206 x sell notional. ORF and OCC have no equity equivalent, so reusing the per-share model would understate options cost by orders of magnitude. Index options are REFUSED, not silently mispriced: the schedule adds $0.50/contract this model does not apply. The one unknown, the SEC sell-leg premium, is priced at the modelled winning exit and declared as an assumption rather than buried. 57 tests. Mutation-verified — all six killed: sizing on the mid, rounding contracts up, allowing one contract over budget, accepting adjusted contracts, dropping ORF/OCC, and silently pricing index options. Suite: 416 -> 473 passed, 1 skipped.

It is persisted to JSONL and read back, so using it as permission would mean anything able to replay a stored decision could trade, and an audit record would double as a bearer token. This separates the two: RiskGateResult audit artifact — explains, serialisable, persisted ExecutionAuthorization execution licence — single use, in-process, unloggable Defends against: forgery, expiry, replay, proposal substitution, a stale portfolio, and leakage of the signature itself. Bindings. An authorization is bound by hash to the exact proposal and the exact portfolio it was approved against, plus the snapshot id. The adapter recomputes both hashes from the objects it is actually about to submit, so a Portfolio Manager cannot approve a small order and then send a large one. Signed with HMAC-SHA256 under a per-process secret regenerated at import: an authorization cannot survive a restart, because the market context that justified it did not either. Explicitly NOT a distributed-trust design — moving multi-process requires a real KMS, and that is a design change, not a config change. Construction is gated by a module-private mint token, so the only way to obtain a valid licence is through authorize(). It is a frozen dataclass rather than a pydantic model, and pickling, __reduce__, model_dump() and dict() all raise: the surrounding system persists pydantic models to JSONL and inheriting that behaviour is how a bearer token lands in an audit file. repr and str redact the signature because they surface in logs, tracebacks and debugger frames. Ordering inside verify() is deliberate — identity, signature, expiry, bindings, then replay. The nonce is burned LAST so a request rejected for some other reason does not consume a licence that was otherwise still valid. Refuses to mint for a non-positive quantity: "approved for zero" is not an approval, and its existence would invite a caller to read the presence of an authorization as permission and supply its own size. 38 adversarial tests; every one is an attack rather than a happy path. Includes a 16-thread race proving exactly one caller wins a single licence. Mutation-verified, all seven killed: signature check disabled, mint-token check disabled, nonce never consumed, expiry check removed, portfolio binding ignored, nonce burned before validation, and repr leaking the signature. Suite: 473 -> 511 passed, 1 skipped.

2 Sep 2026 20:25:57 +0000 Subject: [PATCH 10/44] Add the options execution adapter: the single broker boundary The one place an order reaches a broker, kept deliberately small so it is easy to be sure it cannot be bypassed. Two rules are never relaxed. NO VALID AUTHORIZATION -> NO ORDER. The licence is a required positional argument, not an optional keyword with a permissive default, so there is no code path that submits without one. It is verified against the request ACTUALLY being submitted, so approving three contracts and sending three hundred is blocked before the broker is contacted. SUBMITTED IS NOT FILLED, AND UNKNOWN IS NOT FAILED. There is deliberately no FILLED state in this module: it submits, it never observes fills. A timeout, an unexpected exception, a response with no order id, and an unreadable response type all resolve to UNKNOWN, because the order may exist. Calling a timeout a failure invites a retry that double-fills; calling it success invents a position. Only reconciliation may resolve UNKNOWN. Idempotency comes from the authorization nonce: client_order_id is st-, and since the nonce is single-use by construction, a retry after an ambiguous failure collides at the broker rather than opening a second position. Orders are marketable LIMIT at the ask, never market. Option books are thin and a market order can fill far from the quote, which would falsify the max-loss figure the position was sized on. Live accounts are refused structurally in the constructor. 72 tests. Mutation-verified, all six killed: skipping licence verification (fails 29 tests), a timeout reported as REJECTED, a response with no order id counted as SUBMITTED, the quantity cross-check removed, client_order_id decoupled from the nonce, and allowing a live account. Also fixed a flaw in my own test fixture found while running these: FakeBroker substituted its default success payload for a None response, so the None case never actually reached the adapter. Replaced with a sentinel. Suite: 511 -> 545 passed, 1 skipped.

Alpaca returns several risk-critical numbers as STRINGS (open_interest, close_price, contract size); a silent str/float confusion would not raise, it would produce a contract whose multiplier is wrong and a position sized against a maximum loss that does not exist. Every field is converted explicitly and anything unconvertible DROPS the contract rather than defaulting it — a dropped contract just leaves selection fewer candidates and it fails closed, a silently defaulted one does not. A data outage raises rather than returning an empty chain, because empty is indistinguishable from "no contract qualified", which reads as a legitimate no-trade. app/options_orchestrator.py keeps the deterministic risk engine's authority intact. Its rules (account halts, score, EV, duplicates, correlation, spread, gap, TTL) all still apply to the underlying signal, so the engine still decides MAY WE TRADE and AT WHAT FRACTION OF RISK. Only its share-count arithmetic is replaced: the options layer converts the engine's authorized risk budget into contracts and can never widen it. A REJECT ends the cycle before a contract is even selected. DecisionLog.options_trace records how the signal became a position — the chosen contract, why, what was considered and rejected, the engine's risk multiplier, the sizing arithmetic with its caps, and the estimated fees. Structured rather than a message string so the choice can be queried and re-derived; a contract selection that cannot be reviewed afterwards is not auditable. 17 integration tests covering the full path and every fail-closed branch: no tradeable contract, a data outage, an illiquid chain, a premium larger than the risk budget, a broker timeout (UNKNOWN, not retried), and a risk rejection never reaching contract selection. Two real defects found and fixed while testing, both mine: - _finish() had `state` as both the system state and the execution state, so every submitted-order path raised TypeError. Renamed to system_state / execution_state. - the leak test scanned for the substring "_token", which false-positives on the pre-existing total_token_cost field. Replaced with an exact check: the real nonce for the run is recovered from the broker's client_order_id and asserted absent from the stored decision. Suite: 545 -> 601 passed, 1 skipped.

charset=UTF-8 Content-Transfer-Encoding: 8bit The hackathon requires Alpaca's Trading API via its MCP server or CLI. Alpaca's official MCP server is built so an LLM can trade in plain English — wired the obvious way it is exactly the architecture this project argues against: a language model with direct broker authority and nothing deterministic between. So it is used as a TRANSPORT beneath the safety gate, not as an agent's hand. An order reaching this module has already been scored by S07, gated by the deterministic risk engine, sized by the options risk model and bound to a single-use ExecutionAuthorization. Nothing else in the system holds a reference to the broker, so no LLM can reach place_option_order without passing every gate. The MCP server is genuinely in the path while the authority to trade stays deterministic. Verified against the real package (alpaca-mcp-server 2.3.1): the tool is place_option_order and it documents client_order_id as an idempotency key safe to retry after a timeout — independently confirming the nonce-as-idempotency-key design already built into the adapter. Failure classification is the point. REJECTED (definite, no order exists) is only returned when the server clearly refused; a timeout, transport error or unparseable reply is UNKNOWN, because misclassifying ambiguity as rejection is what makes a retry double-fill. Numeric fields are sent as explicit strings so the number reaching Alpaca is the number that was authorized. Paper mode is forced regardless of ambient environment, live is refused structurally, and credentials are never stored on the instance, logged, or put in an exception. 33 tests covering argument mapping, failure classification and result parsing — everything that decides what reaches the broker and how a failure is read. The stdio transport itself needs credentials and is therefore not exercised in CI. Suite: 601 -> 634 passed, 1 skipped.

Sep 2026 00:57:36 +0000 Subject: [PATCH 13/44] Add order reconciliation: resolve UNKNOWN instead of guessing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The adapter can only say SUBMITTED or UNKNOWN, and its own docstring said "reconciliation owns everything after it" — but reconciliation did not exist. That left the most dangerous state in the system with no resolution path, which is an unfinished promise in the safety model rather than a missing feature. UNKNOWN is never resolved locally. Both local instincts lose money: assuming the order failed retries it and double-fills, assuming it worked invents a phantom position the risk engine then sizes around. It is resolved by asking the broker for the order by the client_order_id already sent, which is derived from the single-use authorization nonce and is therefore a stable handle for exactly one intended order. What it may NOT do is as important as what it does. It observes, classifies and reports; it cannot submit, amend, cancel or retry, holds no authorization and cannot mint one. A component that both decides what is true and acts on it can hide its own mistakes. Ambiguity escalates rather than resolving itself: - an unrecognised broker status is NEVER defaulted to a benign one; a new Alpaca status must be classified deliberately - suspended / stopped / calculated / done_for_day / replaced -> NEEDS_HUMAN - a symbol mismatch, quantity mismatch, overfill, or "filled with zero quantity" all escalate: our model and the broker's disagree - a broker outage leaves the order UNRESOLVED, never optimistically closed - NEEDS_HUMAN is deliberately not terminal; treating it as settled is how ambiguity gets buried safe_to_retry is true ONLY for NOT_FOUND and REJECTED — the two cases where no order provably exists. Every other state has, or may still acquire, a position. 48 tests. Mutation-verified, all five killed: unknown status defaulting to OPEN, retry allowed from any non-filled state (fails 13 tests), discrepancies no longer escalating, a broker outage silently resolving to NOT_FOUND, and NEEDS_HUMAN treated as terminal. Suite: 634 -> 682 passed, 1 skipped.

From: Claude Date: Thu, 3 Sep 2026 01:02:32 +0000 Subject: [PATCH 14/44] Add the adversarial AI layer: the model can only VETO, never authorize MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is an AI trading agents hackathon and the system had no AI. The obvious build is a swarm of analysts that PROPOSE trades with guardrails around them — which is what the reference architectures competitors will copy do, and what this project exists to argue against. So the relationship is inverted. By the time the AI is consulted the trade already exists: produced by S07, gated by the deterministic risk engine, sized by the options risk model. The AI's whole vocabulary is CONFIRM / ABSTAIN / VETO. There is no output that enlarges a position, loosens a limit, changes a strike or authorizes anything. That is not enforced by prompt instructions — a prompt is a request, and prompt injection is real. It is enforced by the SCHEMA: the review object has no field capable of expressing "trade more" (additionalProperties: false, four fields). A hostile model returning quantity 99999 changes nothing, proven end to end against the real pipeline. Model capability is therefore a reasoning decision, not a safety one: swap in the strongest model available and its maximum authority is still to cancel one trade. FAILING CLOSED HERE MEANS "CHANGE NOTHING", NOT "BLOCK EVERYTHING". Because the layer can only subtract, its correct failure mode is inverted: a timeout, malformed JSON, a refusal, an unreachable vendor or an absent reviewer all ABSTAIN and the deterministic decision stands. Vetoing on error would turn an LLM vendor outage into a trading outage — mutation-tested, and making failures veto breaks 22 tests. Provider abstraction per the owner constraint: llm/providers/base.py imports no vendor SDK, so OpenAI / DeepSeek / OpenRouter / local Qwen are one adapter file away with no change to agent or risk code. DeterministicProvider is the no-credential fallback — a judge cloning this repo with no API key still gets a complete end-to-end run and an honest "no model was consulted" instead of invented reasoning. The demo never depends on a third party being reachable. Bull argues for, Bear hunts failure conditions, Judge decides. Bull exists to keep Bear honest: a lone critic always finds something, and a veto that fires every time is the same as having no AI. Only the Judge's verdict has effect. Market context is fenced as and the model is told never to follow instructions found there — and because the schema cannot express an escalation, a successful injection still cannot exceed a veto. That makes injection a denial-of-service risk here, not a financial one. Also fixed: configs/model_config.yaml pinned "claude-haiku-4-5-20251001". Current model ids carry no date suffix, so that was not a valid id. 43 unit tests (all attacks) + 6 integration tests. Mutation-verified, all five killed: unknown verdict coerced to CONFIRM, failures vetoing, a bear veto cancelling a trade, confidence clamped instead of rejected, and context no longer fenced. Suite: 682 -> 731 passed, 1 skipped.

charset=UTF-8 Content-Transfer-Encoding: 8bit A demo that needs an API key and a live market is a demo that fails in front of a judge. This one runs with no credentials, no network and no configuration: python scripts/run_options_demo.py It is not a mock of the system, it IS the system. Bars are synthetic, everything downstream is real: the actual SnapshotBuilder (so validation and feature computation run exactly as against live Alpaca data, including the genuine 891-bar EMA200 convergence requirement), the real S07, the real deterministic risk engine, real contract selection, real sizing, a real single-use authorization, and the real execution adapter. Only the broker and the LLM are substituted — and with credentials present the same interfaces are served by the Alpaca MCP server and Claude. Six scenarios, each demonstrating a different guarantee: breakout approved -> 3 contracts, $960 max loss inside a $1,000 budget veto the AI cancels a deterministically-approved trade; nothing is sent no-signal S07 declines; the decision is still recorded illiquid spread too wide on all 3 contracts -> no tradeable contract broke one contract costs $6,200 against a $1,000 budget -> rejected timeout broker times out -> UNKNOWN, not retried, never assumed filled Every scenario prints the deterministic check count, the contract and why it was chosen, the sizing arithmetic, the AI verdict with the model behind it, and the JSONL file the decision was appended to.

The README is aimed at a judge with sixty seconds: what the system does differently, how to run it with no API key, and how to verify each safety claim rather than take it on trust. Both lead with the actual differentiator — the AI can veto a trade but can never cause one, enforced by the review schema rather than by prompt instructions — and both state the inverted failure mode, since "fail closed" meaning "change nothing" is the counter-intuitive part. A "What is NOT built" section is included deliberately: only S07 of S01-S14 is ported, vertical spreads are declared but refused, Greeks and memory do not exist, parity with MT5 is specification-level and not runtime-verified, and no P&L claim is made anywhere. A README that implies more than exists is the first thing a reviewer catches. Every figure was verified against the code before writing rather than recalled: 732 tests, 22 deterministic checks in the demo path, $960 max loss inside a $1,000 budget. The mutation count was initially written as 30; recounting the runs gave 34, and both documents were corrected upward rather than left with a number that happened to sound plausible.

The network path needs credentials and is rightly not exercised in CI, but the logic deciding HOW a failure is classified is pure and was untested — and it is the part that matters, since every outcome must end as an abstention rather than as a decision. Now covered: timeouts vs unavailability, an unrecognised exception still translating rather than escaping past the abstention handler, a refusal treated as malformed output instead of a parsed answer, an empty reply refused, only text blocks contributing, and the SDK timeout being passed in SECONDS (milliseconds would be a 1000x error in the wrong direction). Also pinned: model ids carry no date suffix. That is asserted structurally now rather than relying on review to catch a recalled variant like "claude-haiku-4-5-20251001", which was the exact bug found in model_config.yaml. options/risk.py policy validation was uncovered, so an incoherent policy (zero or negative risk percentage, zero max contracts, an out-of-range concentration cap) had nothing proving it fails loudly instead of sizing a position from it. Final sweep: no credential-shaped literals, environment=paper, replay execution disabled, risk config fail-closed with the kill switch on, MQL5 reference unmodified, error-lint clean. Suite: 732 -> 769 passed, 1 skipped. README and one-pager counts updated.

Agent M's write-up names it directly ("unspecified LLM providers create reproducibility and accountability gaps"); Alpaca's own reference article disclaims that LLMs "can produce inconsistent, incomplete, or inaccurate outputs". SpeedTrader can reproduce its decisions, because the part that decides is deterministic. This makes that checkable rather than merely claimed. A 16-char hash identifies WHAT THE DETERMINISTIC SYSTEM DECIDED, and replay re-derives it from the stored snapshot alone. THE CENTRAL CLAIM, REDUCED TO COMPARING TWO STRINGS. The fingerprint deliberately EXCLUDES the AI review, so the same market state yields the same fingerprint whether the model confirmed, abstained, timed out, returned hostile output, or was never configured. Proven end to end: a CONFIRM run and an ABSTAIN run of the same market state produce identical fingerprints. Replay then re-derives it with the model entirely absent — if the result is identical without the model, the model demonstrably did not influence it. A VETO does change the outcome, so it is tracked BESIDE the fingerprint rather than folded into it. Merging them would destroy the ability to prove the property above; keeping them separate makes the veto visible as an auditable act rather than an invisible influence. The payload is an allowlist built field by field, not a denylist. A denylist silently absorbs each new schema field into the hash and would invalidate every historical fingerprint the moment the schema grows. Replay is structurally incapable of trading: it is handed no adapter and no registry, tested by asserting those names do not appear in its source. It writes to its own store, never the production journal — an append-only audit trail a replay tool can append to is not one. It uses the snapshot's ORIGINAL timestamp, never the current clock, because re-deriving from "now" would leak information that did not exist at decision time. Divergence reporting names the differing field. "Not reproducible" alone is useless; an auditor needs to know which field moved, because that points at the code change responsible. 51 tests. Mutation-verified, all three killed: smuggling ai_review into the fingerprint (breaks 12 tests), dropping the risk checks from the identity, and replaying against the current clock.

+0000 Subject: [PATCH 19/44] Add a deterministic signal backtest with walk-forward and cost sensitivity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit WHAT IT MEASURES, AND WHAT IT REFUSES TO. This backtests the UNDERLYING S07 signal, not the options expression, and the disclaimer leads every report. That is a data fact, not a shortcut. Backtesting the options expression needs historical option chains — bid/ask per contract per day — which this repository does not have and which no credential here can fetch. The only way to produce option prices without them is a pricing model plus a volatility assumption, and a backtest built that way measures THE PRICING MODEL, not the strategy. It would yield confident-looking numbers that are an artefact of an assumption nobody validated. So the question the data supports is answered, and options P&L is left unanswered rather than answered wrongly. Look-ahead is prevented structurally. The strategy is shown bars[:i] and the outcome resolved from bars[i:]; the sets never overlap, so the mistake is impossible rather than merely avoided. Verified by extending a series with wild future bars and asserting earlier decisions are unchanged. Every ambiguity resolves pessimistically. A bar containing both the stop and the target is scored a LOSS, because OHLC cannot reveal intrabar order and the optimistic branch is exactly how backtests flatter themselves. A trade that never resolves is excluded from win rate and expectancy and counted separately, since dropping it silently biases results toward whichever side happened to resolve. With no trades, win rate is None rather than 0.0 — zero reads as a measured 0%, not as an absence of evidence. No Sharpe ratio, deliberately. On a few dozen trades it is noise wearing a suit and would imply confidence the sample cannot support. Expectancy in R, win rate, profit factor and max drawdown are reported instead, each beside its sample size, with an explicit warning under 30 resolved trades. Walk-forward is validation, not optimisation: S07's constants come from the MQL5 source and are never tuned per window, so every window is genuinely out of sample. Cost sensitivity re-scores the SAME trades at several assumptions rather than re-simulating, because cost does not change which signals fired — the point is to show where the edge dies. An expectancy that survives 0.0R and not 0.05R is a rounding error, and this makes that visible. 30 tests. Mutation-verified, 6 of 6 killed after strengthening one: M2 initially SURVIVED. Letting the entry bar resolve its own trade passed all 30 tests, because the fixture happened to reach the same verdict either way — a fake-positive test. Rebuilt so the last SEEN bar contains the target and no later bar does: correct code reports UNRESOLVED, a backtest that peeks backwards reports a win. The mutant now dies. Suite: 820 -> 850 passed, 1 skipped.

No server, no CDN, no build step, no network — a judge opens the file. Asserted by test: the page contains no external reference at all. THE HERO IS NOT P&L, IT IS THE SEPARATION OF AUTHORITY. Every decision renders three visually distinct lanes so the central idea is legible without reading source: AI · advisory violet CONFIRM / ABSTAIN / VETO, and nothing else DETERMINISTIC · authority blue decides IF and HOW MUCH EXECUTION · outcome aqua what the broker actually did Each card states "changed outcome: YES/NO" for the AI, which is NO on every confirm and abstain and YES only on a veto — the claim made concrete per decision rather than asserted in a README. The deterministic fingerprint is shown on each card, so two identical market states are visibly identical. "Why we did NOT trade" is its own section, attributing every declined decision to the layer that stopped it. Most systems only show the trades they took; the rejected ones are the more interesting half of an auditable system. Colours are the validated dark steps from the data-viz reference palette (#3987e5 / #199e70 / #9085e9), run through the palette validator against the #12141a surface: all six checks PASS. The first attempt used the LIGHT violet step and failed the lightness band and 3:1 contrast on a dark surface — caught by running the validator rather than eyeballing it. Status colours are the reserved four and always ship with a text label, never colour alone. Two real bugs found while wiring it up: `.get(key, {})` returns None when the key exists with a null value (a rejected decision legitimately has candidate: null), and doubled braces inside an f-string expression became a set-of-dict rather than a dict literal. 25 tests.

The typeface stays a system stack rather than IBM Plex over Google Fonts, and that was decided by a test rather than by taste. Adding the webfont link broke test_the_page_is_self_contained, which asserts the page reaches for nothing external. Self-containment is a functional promise to a judge on a locked-down network or no network at all; the typeface is cosmetic. Weakening the test to allow a font host would have traded a guarantee for an aesthetic, so the webfont was reverted instead. Suite unchanged at 875 passed, 1 skipped.

Three deliberate choices, each of which is a way this could mislead: - MAX LOSS IS ALL-IN: premium plus estimated fees. The headline number a reader trusts has to be what the position can actually lose, not the part of it that is convenient. - MAX PROFIT IS NOT A NUMBER. For a long call it is unbounded, and a large figure printed beside an exactly-known max loss is precisely how a reader is led to a false expectation. It is returned as a statement. - DTE IS MEASURED FROM THE SNAPSHOT, not from now, so a decision replayed next week still reports the DTE it actually faced. The contract is recorded as priced at the ASK. The mid is not a price anyone will sell to you at, and sizing against it would understate the cost and make the max-loss figure untrue. 12 tests, including unreadable bid/ask, a non-mapping contract and an unparseable expiry — each degrades to a missing field rather than raising.

OPTIONS OPPORTUNITY — full quote, strike/expiry/DTE, open interest with a thin-book flag, budget utilisation, and the selection reason with how many contracts were considered. Max loss all-in and labelled EXACT; max profit stated rather than quantified; "priced at the ask" shown, because that is what makes the max-loss figure true. WHY THIS TRADE / WHY NOT TRADE — one card summarising the whole pipeline, derived from the inspector so it cannot drift from the detail below it. A rejected decision names the blocking stage, its authority layer, the exact reason code, and states the consequence: EXECUTION BLOCKED, no order sent. DECISION FUNNEL — counts of what happened to every candidate. Rates are WITHHELD below 20 decisions: a percentage from a handful reads as a measured property of the strategy when it is noise. Counts are always shown, because counts are facts. STRATEGY ACTIVITY — signals and their fate per strategy, with no win rate, Sharpe, alpha or profitability. Not withheld from modesty: they are undefined without resolved trades, and printing 0.0 would invite reading absence of evidence as evidence. FIXED, spotted in the rendered page: the health panel listed the literal string "none" as a model name, and reported a scripted deterministic stand-in as an AVAILABLE AI provider. Placeholders now count as no model, and a scripted provider reads SCRIPTED with "not a language model — no LLM reviewed these decisions". Overstating what reviewed a trade is exactly the kind of claim this project cannot afford. Also removes the superseded opt_html block the options panel replaced. Still zero JavaScript, re-asserted. 92 dashboard tests (was 62).

Two ways it was lying: * The displayed order (AI VETO before OPTIONS and RISK) was not the order the orchestrator runs, which is snapshot -> quant -> risk gate -> options -> AI review of an already-approved trade. Drawing the model first inverts the one claim this project makes about where authority lives. RESEARCH and BULL/BEAR are gone from the strip for the same reason: the inspector already reports the debate as NOT BUILT when it did not run, and lighting them green claimed stages that never executed. PORTFOLIO is gone because portfolio heat is one of the 22 checks inside the risk gate, not a separate recorded stage. * Everything after the risk gate was derived from an `execution` block the orchestrator never persists — `_finish` carries the broker outcome on the in-memory result, not onto the record. So every decision that reached Alpaca rendered as though the portfolio gate had stopped it, and the broker lane printed "not submitted" directly beneath a reason line saying the outcome was UNKNOWN. That is a false negative in the one direction that matters: an UNKNOWN submission may already be an order, and the page must never say otherwise. Both now read the decision state and the reason beside it, and an UNKNOWN counts as having reached the broker. Against the six demo scenarios the strip previously blamed QUANT for both options rejections and PORTFOLIO for both execution outcomes; it now reports OPTIONS and EXECUTION, matching the README's own scenario table. Six regression tests pin this, each verified to fail against the old renderer. No quant, risk, execution, options, replay or safety logic is touched — the change is confined to the observer. Docs, audited against the repository rather than edited globally: * 1116 -> 1122 tests (the six above), verified by running the suite. * "49 mutation tests: 76 killed" was self-contradictory; the harness defines 78 mutants, 2 of them declared equivalent. * "breaks 22 tests" for veto-on-failure measured 23 at this commit. * The two real orders are attributed to the development account (PA39QVA871BG) where they were actually placed, not to the dedicated submission account PA3FJIP2GIRB, which has received no orders. * "every record carries ... the execution outcome" softened to what the record actually holds, since no structured execution block is written. * The one-pager, previously linked from nothing, is now in the README's metadata table alongside the engineering log. * The replay count stays 6/6: the journal is gitignored, so that is what a fresh clone prints. An earlier draft of this audit raised it to 57 from a development journal, which no judge would ever reproduce.

Doing this found three - bugs mocks could not: the 100-symbol quote cap; a two-level MCP envelope that - made a *successful* submission read `UNKNOWN`; and a bar window computed in - calendar rather than trading hours, which returned 660 of the 891 bars an - EMA200 needs and so refused **every** hourly symbol — failing closed, and - unable to fail any other way. The safety chain held throughout: the adapter - refused to claim a fill it could not see, reconciliation found the order - `ACCEPTED`, and the retry was refused. An ambiguous success stayed one order. - ---- - -## Bring your own strategy - -S07 is a worked example; the product is everything below it. A trader drops one -file into `strategies/`, runs `strategy_tool.py check`, and inherits all 22 risk -checks, options sizing, the execution licence, reconciliation and the audit -trail — while the contract keeps the boundary absolute: **a strategy proposes a -trade; it cannot size, authorize or place one.** - -Validation *runs* the strategy, because every failure that matters is silent: a -wrong-sided stop (EV computed from a reward that is really a loss), a -non-deterministic `evaluate` (unreplayable), a mutated snapshot, a duplicate id. -Each file's SHA-256 travels onto every decision. Seven mutants prove the guards. -Stated plainly: loading a file executes it, so this enforces the contract, not -safety from hostile code — but no strategy can reach the broker regardless. - ---- - -## Auditability — the differentiator - -Every decision — accepted or not — is appended to JSONL carrying the snapshot, the -signal, **the cost assumptions behind its EV**, all deterministic checks, the -contract chosen *with the alternatives that were rejected and why*, the AI review -with the model and prompt version, and the execution outcome. - -**Decisions are reproducible.** A 16-char fingerprint identifies what the -deterministic system decided and *excludes the AI review by construction*, so the -same market state hashes identically whether the model confirmed, abstained, -timed out or never ran — the central claim reduced to comparing two strings, and -asserted end-to-end by test. `--replay` re-derives every stored decision from its -snapshot with the model absent; a divergence names the field that moved. A veto -is tracked *beside* the fingerprint, never inside it, because it is the one thing -the AI can change. - -A generated command centre renders each decision as three lanes — AI advisory, -deterministic authority, execution outcome — plus **"why we did NOT trade"**, -attributing every declined decision to the layer that stopped it. - -Walk-forward backtesting with cost sensitivity covers the underlying signal; -options P&L is deliberately not simulated, because it would require a pricing -model and would measure that model rather than the strategy. - -The MT5 source is cryptographically pinned in CI so an edit fails the build -rather than silently invalidating the `L####` citations throughout the quant -modules. - -## Stated honestly - -Specification parity with MT5, **not** runtime-verified parity (ADX/DI -normalisation is undocumented and untested against a live terminal). Only S07 of -S01–S14 is ported. Vertical spreads are declared and explicitly refused: a -two-leg order can leg out, so max loss is not exactly known at submission — the -one property long single-leg was chosen for. Greeks and memory are not built. The backtest measures the -underlying signal, never options P&L. **No P&L claim is made anywhere** — paper -trading is a simulation. +known exactly at entry under every price path. Priced at the **ask**, never the +mid — the mid is not a price anyone will sell to you at, and sizing against it +would make the max-loss figure untrue. + +## 3. Alpaca infrastructure + +Orders reach Alpaca through its **official MCP server** (`place_option_order`), +used as a *transport beneath the safety gate* rather than an agent's hand — +nothing else holds a broker reference, so no LLM can reach it without passing +every gate. Options discovery and quotes come from the Trading and Market Data +APIs; fees from the published schedule. **Paper is forced in three independent +places; live is refused structurally.** + +Running against the real API found three defects no fixture could: Alpaca's +100-symbol quote cap, a two-level MCP envelope that made a *successful* +submission read `UNKNOWN`, and a bar window computed in calendar rather than +trading hours. All fixed and pinned by mutants. + +## 4. Deterministic safety + +An `ExecutionAuthorization` is a single-use HMAC licence, per-process secret, +bound by hash to the exact proposal and portfolio, non-serialisable. No licence +→ no order, with no code path around it. **SUBMITTED is never FILLED**; a +timeout is UNKNOWN and resolved by reconciliation, never by a retry that could +double-fill. Execution intent is written to an **fsynced write-ahead journal +before the broker is contacted**, so a crash mid-submission still leaves +evidence an order may exist; on restart the runtime refuses to trade while any +intent is unresolved. + +## 5. Reproducibility and auditability + +Every decision — accepted or not — is appended to JSONL with the snapshot, +signal, cost assumptions, all 22 checks, the contract chosen *and the +alternatives rejected*, the AI review, and the state it ended in with the +reason — `UNKNOWN` included, where an order may exist and reconciliation, not +a retry, resolves it. + +A 16-character fingerprint identifies the deterministic decision and +**excludes the AI review by construction**, so the same market state hashes +identically whether the model confirmed, abstained or never ran. `--replay` +re-derives every stored decision from its snapshot with the model absent. +**Deterministic replay of an LLM response is not claimed** — a model is not +reproducible, which is exactly why nothing it emits is inside the hash. + +Every guard is mutation-tested: **78 mutants, 76 killed, 0 survived, 2 declared +equivalent** with the argument for why. + +## 6.
