taodengandClaude Opus 4.7 a281d3e424 fix: D26 — round-3 small batch (F16+F17+F18+F19)
cold-audit catch from 2026-05-24 (round 3)

4 small fixes batched per Iron Rule 11 IDR cleanup-batch convention.
None exceeds ~15 lines; mixed surfaces (server.mjs / 2 plugins /
plugin header / tests) but all P3-class and related by being honesty
fixes to claims the ADR/spec made but code didn't honor.

Changes (5 files, +546 / -13):

1. server.mjs — TWO changes:
   - **F16 (startup warning)**: `logEvent` function moved earlier in
     the file (was at line ~124, now at line ~56) so it's defined
     before `_startupConfig` is loaded. After loading, check
     `_startupConfig.soft_triggers` — if non-empty, emit
     `logEvent('warn', 'soft_triggers_deferred_v1x', ...)` with the
     configured provider names + a descriptive message citing ADR
     0004 Amendment 2. Wires the mitigation that ADR 0004 § Mitigations
     (original pre-Amendment-2 text) requires: "Soft triggers configured
     against such providers issue a startup warning so the user knows
     the trigger will never fire." D22 deferred soft triggers but
     didn't re-implement this mitigation.
   - **F19 (streaming truncation marker)**: in the stop-less exhaustion
     branch of the real-streaming code path (post-D25 F9 — the no-cache
     fix), write a synthetic `{type:'stop', finish_reason:'length'}`
     SSE chunk via `irChunkToOpenAISSE(...)` BEFORE `res.write(SSE_DONE)`.
     Guarded on `streamedChunks.length > 0` (emitting truncation on
     a zero-content response would mislead the client). Mirrors the
     buffered D16 path which already synthesizes the same marker.
     The synthetic marker is `res.write`-only — NEVER pushed to
     `streamedChunks` — so the D25 F9 no-cache invariant
     (cache decision sees the original chunks array unchanged) is
     structurally preserved.

2. lib/providers/codex.mjs + mistral.mjs — F17 stderr propagation:
   the SPAWN_FAILED throw from the error-chunk-in-NDJSON path now
   includes `accumulatedStderr.slice(0, 200)` suffix when non-empty.
   Comment cites ADR 0004 § Chain advancement step 4 ("preserve the
   client's ability to debug — the first failure is the load-bearing
   signal").

   **anthropic.mjs intentionally NOT modified**. Re-analysis confirmed
   Anthropic's SPAWN_FAILED throws are from (a) process.on('error')
   for binary-not-found (already includes OS-level err.message),
   (b) SPAWN_TIMEOUT (separate code, D24 race fix), and (c) post-loop
   exit-code (already includes `accumulatedStderr.slice(0, 300)`).
   Anthropic uses `--output-format text`, so it has no NDJSON
   error-chunk parsing path. The cold-audit was correct that the
   error-chunk class only affects codex + mistral.

3. lib/providers/anthropic.mjs — F18 plugin header self-contained
   D4 observation note. Pre-D26: ALIGNMENT.md anthropic Authority pin
   row cited the plugin header for the OLP-side observation, and the
   plugin header cited ALIGNMENT.md back — circular citation, no
   party documented a fresh observation. Fix: plugin header now
   carries the actual observation ("@anthropic-ai/claude-code v2.1.89
   confirmed present at D4 implementation per ALIGNMENT.md Rule 5").
   ALIGNMENT.md side unchanged (still points to plugin header — but
   now points to a real artifact, not back to itself).

4. test-features.mjs — 9 new tests in 3 describe blocks:
   - F16 ×3: soft_triggers non-empty → warn fires; empty → no warn;
     undefined → no warn. Test uses inline simulation of the startup
     code path (ESM module-eval can't be re-triggered per test process
     without isolation gymnastics; inline simulation exercises the
     same `Object.keys + length > 0 + logEvent('warn', ...)` shape).
   - F17 ×3: codex with stderr → stderr appears in throw message;
     codex without stderr → no suffix; mistral with stderr → suffix
   - F19 ×3: partial-content + stop-less exhaustion → finish_reason='length'
     marker before [DONE]; zero-content + stop-less exhaustion →
     no marker (just [DONE]); D25 F9 invariant preserved (second
     identical request triggers fresh spawn, X-OLP-Cache: miss)

Tests: 349 → 358 (+9). All pass on Node 20.

Authority:
- F16 → ADR 0004 § Mitigations (original) + ADR 0004 Amendment 2 (D22)
- F17 → ADR 0004 § Chain advancement step 4
- F18 → ALIGNMENT.md Rule 1 (Cite First) + Rule 5 (Cite in Commits)
- F19 → OpenAI Chat Completions streaming spec finish_reason enum
  https://platform.openai.com/docs/api-reference/chat/streaming
- CC 开发铁律 v1.6 § 10.x — Round-3 Cold Audit caught all 4

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): APPROVE. Verified critical concerns: (a) logEvent move is
net-zero (1 removed + 1 added; no duplicate); (b) F17 anthropic
non-application is justified by code-reading 3 SPAWN_FAILED sites in
anthropic.mjs (none is the NDJSON-error-chunk class); (c) F18 citation
chain no longer circular (verified BOTH endpoints); (d) F19 critical
no-cache invariant preserved (truncMarker is res.write-only, never
enters streamedChunks; verified both by code-path analysis and by F19
test 3 behavioral assertion).

3 non-blocking suggestions noted (F18 copy redundancy; F16 test linking
comment; F17 stderr slice-depth alignment) — all cosmetic, not folded.

taodengandClaude Opus 4.7 7ef5510837 feat(cache): D23 — implement hints.cacheable + 10MB size cap (round-2 F3)
cold-audit catch from 2026-05-24

Round-2 cold-audit Finding 3 (P2 cache correctness). ADR 0005 § "Cache
write conditions" items 3 and 4 were documented but never wired in
code:
- Item 3: "The provider's hints.cacheable flag is not false"
- Item 4: "The response is below a size cap (default 10 MB; configurable)"

Grep verified zero matches for `cacheable` / `10485760` / size-cap
patterns in lib/ or server.mjs pre-D23.

Changes (9 files, +391 / -12):

1. docs/adr/0002-plugin-architecture.md — Amendment 3 adds `cacheable`
   to the Provider contract hints list (after D11's Amendment 1 added
   maxSpawnTimeMs). Authority chain cites ADR 0005 § Cache write
   conditions item 3 as the field's origin.

2. docs/adr/0005-cache-cross-provider.md — Amendment 3 documents the
   D23 implementation of items 3 + 4 + the D16-interaction edge case
   (truncated > 10MB → no-op eviction, structurally bounded since
   responses > 10MB are anomalous by ADR's own rationale).

3. lib/providers/base.mjs — ProviderHints typedef gains
   `[cacheable]` (optional boolean); validateProvider rejects non-
   boolean non-undefined values. Omission accepted (default = true).

4. 3 plugins (anthropic / codex / mistral) each declare
   `cacheable: true` explicitly with citation comment.

5. lib/cache/store.mjs — CacheStore constructor accepts
   `maxEntryBytes` (default 10 * 1024 * 1024 = 10_485_760) +
   injectable `_warnFn`. `set()` computes
   `Buffer.byteLength(JSON.stringify(value))`; if exceeded, warns via
   `_warnFn` and returns undefined (no persistence). `getOrCompute`
   still returns the computed value to caller — cache write skipped
   but caller gets data; subsequent identical requests re-spawn.

6. server.mjs — 4 sites coordinated for cacheable opt-out:
   - `executeHopFn`: cacheable check before D13 shouldBypassCacheForHop
     (permanent provider policy precedes per-request bypass condition)
   - `cacheStore.peek` gate at line ~504: `cacheableForFirstHop`
     short-circuit
   - Real-streaming branch entry condition at line ~522:
     `cacheableForFirstHop` added (so cacheable: false + stream falls
     through to buffered path which honors the opt-out via executeHopFn)
   - Both `cacheStore.set` sites in streaming branch wrapped in
     `if (cacheableForFirstHop)` defensive guards (post-D23
     restructure these are unreachable for cacheable: false, but the
     guards make intent explicit and survive future refactors)

7. test-features.mjs — 13 new tests:
   - 5 validator tests (Suite 4): explicit true/false, omitted, string
     rejected, number rejected
   - 5 size-cap unit tests (Suite 9): default 10MB, custom override,
     oversize skip + warn capture, within-limit normal persistence,
     getOrCompute oversize returns-but-doesn't-cache + re-spawn
   - 3 cacheable integration tests (Suite 9e): non-streaming opt-out,
     streaming opt-out (the regression case that pre-fold-in failed),
     X-OLP-Cache header consistency on both paths

Tests: 335 → 348 (+13). All pass on Node 20.

Pre-commit fold-in (per evidence-first checkpoint #4):

- **D23 reviewer flagged 2 blocking issues**: (1) the cacheable opt-out
  in initial implementation was only in `executeHopFn` (buffered path);
  the D10 real-streaming branch in server.mjs bypassed the check
  entirely — calling streamPlugin.spawn() directly and writing to
  cacheStore.set() at 2 sites without consulting cacheable. (2) Suite
  9e integration tests didn't cover stream: true so the leak wasn't
  caught.

  Both diff-review and the implementer focused on `executeHopFn`
  because that's where the cold-audit reviewer pointed for Finding 3.
  Same class of "narrow attention" miss as several earlier D-days.

  Fold-in: compute `cacheableForFirstHop` once at request entry; add
  `!cacheableForFirstHop` short-circuit to peek gate; add
  `cacheableForFirstHop` to streaming-branch entry condition (forces
  fall-through to buffered path which has the opt-out); add defensive
  guards on both `cacheStore.set` call sites. Added a 3rd Suite 9e
  test covering stream: true + cacheable: false (which pre-fold-in
  would have failed by serving the second request from cache).

  This is now the FOURTH D-day where a doc-vs-code or path-coverage
  gap was caught by the reviewer rather than the implementer. The
  v1.6 § 10.x diff-review discipline continues to pay off.

Default behavior unchanged for 3 shipped plugins (all explicitly
`cacheable: true` → cache path identical to pre-D23).

Authority:
- ADR 0002 Amendment 3 (in-place) — establishes cacheable in contract
- ADR 0005 Amendment 3 (in-place) — documents implementation of items
  3 + 4
- ADR 0005 § Cache write conditions items 3 + 4 — the original
  authority for both rules
- CC 开发铁律 v1.6 § 10.x — Round-2 Cold Audit caught the missing
  implementation; diff-review Mode A caught the streaming-path gap

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): REQUEST_CHANGES on initial, APPROVE after fold-in (implicit
— fold-in followed the exact recommendation). Verified:
- ADR amendment placement + structure
- Validator typedef + checks
- Size cap implementation in CacheStore + inflight slot release on
  oversize-skip
- All 4 interaction cases (cacheable × cache_control × D16
  × ordering) coherent post-fold-in
- 13 new tests including the regression test that would have failed
  on pre-fold-in code

Follow-up items (reviewer's non-blocking notes, NOT in this PR):
- ADR 0005 Amendment 3 could add one sentence on the prior-write-also-
  oversize case (file as docs polish)
- Consider extracting `shouldUseCacheForHop(hopProvider, ir)` helper
  combining D13 + D23 logic — reduces miss-risk for next reviewer
- Test 30 could add `assert.equal(store._inflight.size, 0)` as
  inflight-slot leak regression guard

taodengandClaude Opus 4.7 f8348adb3b fix(providers): D24 — close spawn-timeout race when timer fires during yield-suspension (round-2 F4)
cold-audit catch from 2026-05-24

Round-2 cold-audit Finding 4 (P2 concurrency bug). All 3 provider plugins
(anthropic / codex / mistral) had a race in spawn-timeout enforcement:

The timer's rejection branch is `if (rejectNext) { rejectNext(SPAWN_TIMEOUT) }`.
`rejectNext` is only set while the drain loop is AWAITING an empty-queue
promise. If the timer fires while the generator is suspended at a `yield`
(rejectNext === null because we're not currently awaiting), the rejection
is silently skipped. The loop then drains queued items, sees `close`
(from the SIGTERM), breaks normally. Post-loop guards on `!spawnTimedOut`
both skip: SPAWN_FAILED throw + yield-stop emit. Generator returns
normally with N partial chunks. Consumer (collectAllChunks) sees a
"successful" return. Fallback never advances. Truncated response gets
cached.

This violates BOTH:
- ADR 0004 § Trigger taxonomy bullet 4 (hard trigger never fires)
- ADR 0005 § Cache write conditions item 1 (truncated response cached)

The bug escaped FOUR reviewers: D10 diff-review, round-1 cold-audit, D11
reviewer, D14 reviewer. Round-2 cold-audit caught it because it was
unprimed and walked the timer/drain-loop race manually.

Fix (3 plugins, parallel race):

Each plugin gains an unconditional post-loop check, placed AFTER the
existing `try { drain loop } finally { clearTimeout(timer) }` block,
but BEFORE the existing `!spawnTimedOut`-gated guards:

```js
if (spawnTimedOut) {
  throw new ProviderError(
    `<cli-name> spawn timed out after ${maxSpawnTimeMs}ms`,
    'SPAWN_TIMEOUT',
  );
}
```

This closes the race surface: the inner-loop guard (unchanged, lines
~319/461/583) handles the rejectNext-set path; the new post-loop guard
handles the rejectNext-null path. Together they cover both halves —
SPAWN_TIMEOUT now reliably surfaces as a hard trigger regardless of
which path the timer fire took.

Changes (4 files, +154 / -0):
- lib/providers/anthropic.mjs: post-loop guard at lines 360-365 (after
  clearTimeout at line 348-350, before existing SPAWN_FAILED guard at 368)
- lib/providers/codex.mjs: post-loop guard at lines 521-526 (parallel)
- lib/providers/mistral.mjs: post-loop guard at lines 643-648 (parallel)
- test-features.mjs: new Suite 16 test 16e — race reproduction (109 lines)

Test 16e race reproduction (deterministic):

Exploits Node event-loop ordering. Mock spawn schedules data1 + data2 +
close via a single setImmediate. setImmediate runs before timers in the
same tick, so all 3 events queue before the timer can fire. Generator
yields data1 then suspends at yield with rejectNext null. Consumer
pauses 25ms (> 10ms timer). Timer fires during yield-suspension:
spawnTimedOut=true, rejectNext null → branch skipped, SIGTERM sent.
Consumer resumes, drain processes data2 + close, breaks normally.
Post-loop: D24 guard catches spawnTimedOut → throws SPAWN_TIMEOUT.

Pre-D24 behavior: generator returns normally (truncated, silently
cacheable). Test would FAIL.
Post-D24: SPAWN_TIMEOUT throws → test PASSES.

Reviewer empirically validated the test's diagnostic power by stripping
D24 from anthropic.mjs and observing exactly 16e fail (only 16e — 16a
through 16d still pass on the orthogonal rejectNext-set path), then
restored.

Timing flake risk: very low. Race depends only on relative ordering of
two setTimeout callbacks (10ms vs 25ms) which Node guarantees regardless
of absolute drift. Reviewer ran 7 npm test passes; 16e timing spread
26.43-27.70ms (1.3ms variance).

Tests: 334 → 335 (+1). 335/335 pass on Node 20.

Out of scope (filed in issue #3):
- SPAWN_TIMEOUT salvage parity: this fix discards partial chunks (matches
  current SPAWN_TIMEOUT semantics, doesn't introduce asymmetry vs
  SPAWN_FAILED-no-chunks). Whether to add SPAWN_TIMEOUT-with-usable-chunks
  salvage (analogous to D16's SPAWN_FAILED salvage) is a separate design
  decision tracked in issue #3.

  spawn timeout (configurable per-provider via hints.maxSpawnTimeMs)"
  https://github.com/dtzp555-max/olp/blob/main/docs/adr/0004-fallback-engine.md

- engine.mjs HARD_TRIGGER_CODES['SPAWN_TIMEOUT'] = true (D10 P1.3,
  unchanged)
- CC 开发铁律 v1.6 § 10.x — Round-2 Cold Audit caught this

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): APPROVE. Verified guard position in all 3 plugins; read
push() to confirm rejectNext-null mechanism; empirically validated test
16e's diagnostic specificity (strip-revert-restore); 7 test runs
confirmed timing stability. No blocking issues.

taodengandClaude Opus 4.7 ed82e65859 chore: D19 — cleanup batch (Findings 8 + 14 + 15 + D17 dead import)
cold-audit catch from 2026-05-23

Batched 4 small P3 mechanical cleanups per Iron Rule 11 IDR cleanup-batch
convention (all P3, all small, no semantic feature changes beyond defensive
validation).

Changes (7 files):

1. lib/ir/ir-to-openai.mjs (+30 / -3) — Finding 8 defensive validator:
   - Added OPENAI_FINISH_REASON_ENUM Set with the 6 spec-allowed values
     (stop / length / tool_calls / content_filter / function_call / null)
   - Added normalizeFinishReason(value) helper that returns value unchanged
     if in enum, else 'stop'
   - Routed both irChunkToOpenAISSE (streaming path) and
     irResponseToOpenAINonStream (non-stream path) through the helper
   - Bonus tightening (in-scope, same finish_reason concept):
     irResponseToOpenAINonStream's gate changed from `if (chunk.finish_reason)`
     (truthy check) to `if (chunk.finish_reason !== undefined)` so an
     explicit null (valid spec value meaning "still in progress") is no
     longer silently dropped by the truthy guard
   - Note: undefined → null collapse via `?? null` is unreachable in the
     current codebase (all provider plugins explicitly set finish_reason
     on stop chunks); defensive only against a future plugin that omits
     the field — documented inline

2. .github/workflows/alignment.yml (-16) — Finding 14 dead CI cleanup:
   - Removed `setup.mjs` from path triggers (push + pull_request) — the
     file does not exist in the repo
   - Removed the dead `KNOWN_PROVIDERS=(...)` bash array from job 1 and
     its comment block — no later step iterated over it, so the array
     was abandoned
   - LEFT untouched: the Node.js inline KNOWN_PROVIDERS array in the
     models-registry validation job — that one is actively consumed by
     the schema validation script

3. lib/providers/anthropic.mjs / codex.mjs / mistral.mjs (3 × 1 line) —
   Finding 15: removed unused `PROVIDER_ERROR_CODES` from import lines.
   Each line went from `import { ProviderError, PROVIDER_ERROR_CODES } from
   './base.mjs';` to `import { ProviderError } from './base.mjs';`. The
   constant remains exported from base.mjs (its declaration site, where
   it IS used for validation).

4. server.mjs (1 line) — D17 reviewer's observation: removed unused
   `getProviderForModel` from the import line. The function is only
   called by lib/fallback/engine.mjs which imports it directly from
   lib/providers/index.mjs. server.mjs's import was dead (the routing
   SPOT lives in engine.mjs after D17 — server.mjs uses buildDefaultChain
   exclusively).

5. test-features.mjs (+44) — Suite 3 (irChunkToOpenAISSE format) extended
   with 4 new finish_reason normalization tests:
   - Test 1: non-spec streaming finish_reason ('timeout', 'overloaded',
     'cancelled') → mapped to 'stop'
   - Test 2: spec-enum streaming finish_reason (all 6 incl. null) preserved
   - Test 3: non-spec non-stream finish_reason → mapped to 'stop'
   - Test 4: spec-enum non-stream finish_reason preserved (null
     intentionally omitted — documented inline)

Tests: 324 → 328 (+4). All pass on Node 20.

Pre-commit fold-ins (per evidence-first checkpoint #4):

- **D19 reviewer suggestion #1**: added inline comment to
  normalizeFinishReason explaining the unreachable `undefined → null`
  branch (defensive only, no current plugin omits the field). Cheap
  future-reader clarity.
- **D19 reviewer suggestion #2**: added inline comment to Test 4
  explaining why null is intentionally omitted from the spec-enum list
  (non-stream `!== undefined` gate enters with null and overwrites
  default 'stop' to null — semantically odd but spec-valid).

Reviewer suggestion #3 (consider stricter `undefined → 'stop'` on
streaming-stop path vs `null → null` on delta path) explicitly marked
out of scope by reviewer — would require call-site context awareness;
filed mentally as potential future work, not tracked as an issue
since no current path triggers it.

Authority:
- ALIGNMENT.md Rule 2(b) — only spec-defined fields in OpenAI responses
- OpenAI Chat Completions spec finish_reason enum
  https://platform.openai.com/docs/api-reference/chat/object#finish_reason
- CC 开发铁律 v1.6 § 10.x — Cold Audit Findings 8 / 14 / 15

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): APPROVE. Verified the unreachable `undefined → null` branch
claim by grep-checking all 3 provider plugins (none emit undefined);
verified the two KNOWN_PROVIDERS arrays were correctly distinguished
(only the dead bash one removed); ran npm test independently to confirm
328/328.

taodengandClaude Opus 4.7 cb86807009 refactor(routing): D17 — alias-aware getProviderForModel as routing SPOT (Findings 12 + 13)
cold-audit catch from 2026-05-23

Cold-audit Findings 12 + 13 (both P3, both routing layer). F12: mistral
plugin's models[] included canonical IDs + aliases while anthropic/codex
were canonical-only — inconsistent routing surface (request "sonnet"
returned 503 from anthropic but request "devstral" worked for mistral).
F13: getProviderForModel imported but never called; buildDefaultChain
duplicated the lookup loop — two SPOT-candidate code paths.

Per cold-audit reviewer's option (a): standardize models[] on canonical-
only across all 3 plugins; getProviderForModel becomes alias-aware via
models-registry.json; buildDefaultChain uses getProviderForModel as SPOT.

Changes (4 files, +242 / -50):

1. lib/providers/index.mjs:
   - At module load, builds `_aliasMap: Map<aliasString, {providerName,
     canonicalModel}>` by walking models-registry.json's providers[*].aliases
   - getProviderForModel signature extended: returns `{provider, name,
     canonicalModel}` (was `{provider, name}`). The canonicalModel field is
     the resolved canonical ID for callers that need to use it downstream
     (cache key, observability headers, log events)
   - 3-step resolution order: (1) alias map lookup → if hit AND provider
     loaded → return with canonicalModel; (2) direct canonical scan → return
     with canonicalModel = modelString; (3) null
   - "Alias known but provider not loaded" case correctly falls through
     to step 2 (which will also miss for an alias string) → returns null

2. lib/providers/mistral.mjs:
   - _registryModels stripped to canonical-only: removed the
     `...Object.keys(_registryEntry.aliases ?? {})` spread
   - mistral.models[] now matches anthropic/codex shape (canonical IDs only)
   - Comment block updated to point future readers at getProviderForModel
     as the SPOT

3. lib/fallback/engine.mjs:
   - buildDefaultChain's inline `for ([name, provider] of loadedProviders)`
     scan loop replaced with a single getProviderForModel() call
   - Chain hop's `model` field is now `match.canonicalModel` (was `modelString`)
     — so downstream consumers receive canonical
   - Explicit-chain config path unchanged (kept its pre-existing behavior;
     alias resolution in routing.chains config is a known limitation, tracked
     as a future improvement)

4. test-features.mjs:
   - 17 new tests in `D17 — alias-aware getProviderForModel` describe block:
     anthropic alias coverage (sonnet/opus/haiku/claude), openai aliases
     (codex/codex-spark/gpt5/gpt5-mini), mistral aliases (devstral/
     devstral-2/devstral-small/devstral-small-2), canonical pass-through,
     unknown model → null, alias-to-disabled-provider → null,
     buildDefaultChain integration with alias resolution
   - 3 existing mistral tests rewritten — they were asserting the pre-D17
     inconsistent shape (aliases in mistral.models[]). Now assert the
     post-D17 invariant (aliases NOT in models[]; routing via
     getProviderForModel instead)

Tests: 300 → 317 (+17 new). All pass on Node 20.

Pre-commit fold-in (per evidence-first checkpoint #4 — fold-ins themselves
need second-pass review):

- **D17 reviewer flagged C10**: original engine.mjs comment said
  "downstream (cache key, X-OLP-Model-Used, provider.spawn) receives the
  canonical ID rather than the alias string". The provider.spawn portion
  is incorrect — spawn reads `irRequest.model` (the user's original input),
  which is NEVER rewritten to canonical. Each provider CLI accepts its own
  aliases natively (claude accepts sonnet/opus/haiku; vibe accepts
  devstral/devstral-2; codex accepts its model IDs), so runtime behavior
  is fine, but the comment overstated what D17 actually changes.
  Folded in: corrected comment to honestly describe the canonical flow
  (cache key + X-OLP-Model-Used + logs receive canonical; spawn continues
  to receive irRequest.model). Same class of doc-code drift fix as D11's
  B1 (false maxConcurrent enforcement claim) and D16's "bypasses
  getOrCompute" drift — the discipline is maturing across D-days.

  only place to add/edit (provider, model) metadata"
- CC 开发铁律 v1.6 § 10.x — Cold Audit Findings 12 + 13

Reviewer (Iron Rule v1.6 § 10.x Mode A, fresh-context opus, independent
of drafter): APPROVE_WITH_MINOR. Highest-value verification: walked
chain[0].model from buildDefaultChain through all downstream consumers
(computeCacheKey, X-OLP-Model-Used, log events) to confirm canonical
flow; then verified provider.spawn paths in anthropic.mjs:231 and
codex.mjs:248 read irRequest.model (user input), confirming the comment
overstatement (now fixed). Verified no alias-canonical collision exists
in current registry (12 aliases vs 10 canonical IDs, zero intersection).
Verified empty-registry edge case + provider-with-model-not-in-registry
edge case.

Follow-up items (reviewer's non-blocking observations, NOT in this PR):
- server.mjs:32 dead import of getProviderForModel — defer to D19 cleanup
- explicit-chain config path doesn't run alias resolution (routing.chains
  in ~/.olp/config.json) — pre-existing limitation, file as future issue

taodengandClaude Opus 4.7 2cfd0b194e feat(phase-1): D10 P1 hardening — providers.enabled wiring + real streaming + spawn timeout
Folds in three production-blocking defects from external Codex review
round-3 of Phase 1 (D5+D6+D8+D9 already merged). Without these, OLP
returns 503 on every request even when `npm start` succeeds, streams
arrive as a single buffered burst after the spawn completes, and hung
CLIs block the engine forever despite ADR 0004 declaring spawn-timeout
a hard trigger.

P1.1 providers.enabled config wiring (ADR 0002 § Disable model):
- loadFallbackConfigSync() returns tri-field {chains, soft_triggers,
  providersEnabled}; server.mjs reads _startupConfig.providersEnabled
  and passes to loadProviders() at startup
- Empty / missing config → 0 enabled providers → 503 no_enabled_provider
  (matches v0.1 0-Enabled posture per ALIGNMENT.md § Provider Inventory)
- __setProvidersEnabled / __resetProvidersEnabled test seams; in-place
  Map mutation preserves existing direct-mutation patterns in Suite 13

P1.2 Real SSE streaming on single-hop cache-miss (ADR 0003 entry adapter
pattern, OpenAI /v1/chat/completions stream=true contract):
- New handleChatCompletions branch when ir.stream === true && chain.length
  === 1 && !bypassCache && !preCheckHit
- for await (const irChunk of provider.spawn(...)) writes SSE per chunk
  via res.write(irChunkToOpenAISSE(...)); accumulates streamedChunks for
  cacheStore.set on stop
- First-chunk rule preserved: error-before-first-chunk → sendError(502);
  error-after-first-chunk → truncated res.end(), no fallback
- Multi-hop chains (chain.length > 1) continue to use buffered
  executeWithFallback to keep fallback safety semantics

P1.3 Spawn timeout hard trigger (ADR 0004 § Trigger taxonomy bullet 4):
- SPAWN_TIMEOUT added to PROVIDER_ERROR_CODES (lib/providers/base.mjs)
  and HARD_TRIGGER_CODES (lib/fallback/engine.mjs)
- All three plugins (anthropic.mjs / codex.mjs / mistral.mjs) wrap drain
  loop with setTimeout (default 600_000ms, configurable via
  hints.maxSpawnTimeMs); on fire: proc.kill('SIGTERM') + reject pending
  drain promise with ProviderError(..., 'SPAWN_TIMEOUT')
- Timer cleared in finally; resolveNext/rejectNext atomically nulled in
  push() + timer-fire path to prevent late-fire double-settle

Tests 277 → 288 (+11). Suite 14 (4 providers.enabled), Suite 15
(3 streaming cache-miss real-time, including arrival-count >= 2
assertion that architecturally proves real streaming), Suite 16
(4 spawn timeout, including 2-hop chain advancement from timed-out
primary). 288/288 pass on Node 20.20.2 + Node 25.8.0.

Reviewer (Iron Rule 10): fresh-context opus, independent of drafter.
Verdict: APPROVE_WITH_MINOR. Folded the one cheap minor before commit
(Suite 15a arrival-count assertion strengthened from chunks.length > 0
to arrivalTimestamps.length >= 2 — the prior assertion would have
admitted a buffered impl). Two remaining non-blocking notes deferred:
optional writeHead deferral (low value; single-hop guard makes pre-
content 200 + empty body safe), and version bump (Phase 1 ships as
v0.1.0 aggregate when D11–D16 land).

taodengandClaude Opus 4.7 (noreply@anthropic.com) 95dc072245 feat(phase-1): land Mistral Vibe provider plugin (D8)
Phase 1 Day 5. Mistral Vibe provider plugin lands as Candidate. STATIC_
REGISTRY now length 3 (anthropic + openai + mistral). vibe CLI not
installed on the orchestrator machine and owner has no Le Chat Pro
subscription, so D8 follows the D6 docs-only authority pattern. D-later
verification (once a tester with a vibe install and subscription is
available) will resolve UNPINNED assumptions A4, A6, A7, A8.

Files:
  NEW:  lib/providers/mistral.mjs (~720 lines) — Mistral Vibe provider.
        Spawns `vibe --prompt PROMPT --output streaming` per docs.
        Reads MISTRAL_API_KEY env var with ~/.vibe/.env fallback.
        Supports VIBE_HOME env override per docs. Mirrors D4/D6 plugin
        structure incl. __setSpawnImpl/__resetSpawnImpl for tests.
  MOD:  lib/providers/index.mjs (+12/-1) — STATIC_REGISTRY now length 3.
        listAllProviderNames returns [anthropic, openai, mistral].
  MOD:  models-registry.json (+26 lines) — providers.mistral with 2
        canonical date-stamped IDs (devstral-2-25-12, devstral-small-2-
        25-12) and 4 short-form aliases for user convenience.
  MOD:  test-features.mjs — Suite 12 with 48 tests covering contract
        conformance, IR translation, mock-spawn behaviour, healthCheck,
        estimateCost, auth-artifact reading.

Authority citations (all WebFetched and verified during reviewer pass):
  DOCS-1: docs.mistral.ai/mistral-vibe/terminal/quickstart — `vibe
    --prompt PROMPT --max-turns 5 --max-price 1.0 --output json` example
    + Output Format Options enumeration: text default, json single blob,
    streaming NDJSON.
  DOCS-2: docs.mistral.ai/mistral-vibe/terminal/configuration — pin
    `~/.vibe/.env`, MISTRAL_API_KEY env var, VIBE_HOME override.
  DOCS-3: docs.mistral.ai/mistral-vibe/introduction/configuration —
    second confirmation of MISTRAL_API_KEY + ~/.vibe/.env (model
    selection via config.toml `/config` slash command, NOT --model
    flag).
  DOCS-4: deepwiki.com/mistralai/mistral-vibe/9.3-cli-commands-reference
    — full flag enumeration confirms no --model flag exists. Programmatic
    mode trigger is --prompt; flags are: --continue, --max-price,
    --max-turns, --output, --prompt, --resume, --setup, --trust,
    --upgrade, --version, --workdir, --no-autofill, --no-header,
    --no-dev, --enabled-tools, --help.
  DOCS-5: mistral.ai/news/devstral-2-vibe-cli — launch announcement,
    names Devstral 2 (123B) and Devstral Small 2 (24B), 256K context,
    pricing $0.40/$2.00 and $0.10/$0.30 per MTok.
  DOCS-6: help.mistral.ai/en/articles/347532 — Vibe included in Le Chat
    Pro.
  DOCS-7: legal.mistral.ai/terms/usage-policy — no anti-third-party
    clauses; ADR 0006 Tier D classification holds.
  DOCS-MAIN: docs.mistral.ai/mistral-vibe/overview — main Vibe overview.
  DOCS-8: docs.mistral.ai/getting-started/models/models_overview —
    canonical Mistral models registry. Pin for date-stamped IDs
    devstral-2-25-12 / devstral-small-2-25-12. Caught by D8 review-2.

Architectural decisions:
  1. `--output streaming` (NOT `json`). Per DOCS-1 verbatim: streaming
     emits NDJSON per message; json emits a single blob at the end.
     Original D8 draft used `json` which is incompatible with the
     plugin's line-buffered stdout parser. Review-2 caught this; fixed
     before commit.
  2. No --model flag. Per DOCS-4 full flag enumeration there is no
     --model flag in programmatic mode. Model selection happens via
     ~/.vibe/config.toml. The IR's `model` field is used by OLP for
     routing only; Vibe uses whatever model is in user-level config.
     Documented in lossy translations + as A5 CONFIRMED-NOT-APPLICABLE.
  3. Canonical IDs primary, short forms as aliases. models-registry.json
     uses devstral-2-25-12 / devstral-small-2-25-12 as primary `id`s
     matching the canonical Mistral models registry; user-facing short
     forms (devstral-2, devstral-small-2, devstral, devstral-small) are
     aliases. Plugin's models[] array includes both canonical IDs AND
     alias keys so getProviderForModel routes either form. Same pattern
     codified for Codex aliases in D6.
  4. Auth precedence: MISTRAL_API_KEY env > ~/.vibe/.env > null.
     Documented in DOCS-2. readAuthArtifact supports
     MISTRAL_VIBE_AUTH_PATH env override for testing.
  5. Mistral stays Candidate. STATIC_REGISTRY.length === 3 but
     loadProviders({}) returns empty Map; only loadProviders({
     enabled: { mistral: true }}) loads it. POST /v1/chat/completions
     devstral-* still returns 503 until config flag is set and E2E
     audit passes.

Reviewer chain (Iron Rule 10):
  Implementer: sonnet (general-purpose).
  Fresh-context reviewer: opus (ecc:code-reviewer). Verdict round-1:
    REQUEST_CHANGES (2 blockers caught).
  Reviewer ran npm test (222/222 pass), WebFetched all 8 canonical
    Mistral docs URLs, discovered DOCS-8 (models registry) which
    sonnet missed — exactly the D6 failure pattern, repeated. Reviewer
    independently verified `--output streaming` vs `json` semantics
    against the live docs page text, not paraphrases.

Reviewer blocking findings folded in this commit:
  B-1 (--output json wrong): Plugin now passes `--output streaming` per
    docs verbatim. Test "irToMistral: user message → args with --prompt
    and --output streaming" updated to assert the new arg and reject
    the old one.
  B-2 (canonical models page missed): models-registry.json refactored
    to use date-stamped canonical IDs as primary; short forms as
    aliases. mistral.mjs header adds DOCS-8 as the new canonical
    authority pin for model IDs. Plugin's models[] array merges
    canonical + alias keys so existing routing tests pass with either
    form.
  B-3 (404 claim incorrect): mistral.mjs header DOCS-MAIN updated.
    docs.mistral.ai/mistral-vibe/overview is 200 OK; sonnet's 404
    claim was a path-normalization mismatch.

Reviewer non-blocking suggestions (deferred to D-later / not D8 scope):
  - VIBE_HOME env override has no Suite 12 test (implementation
    present at mistral.mjs:262). Parallel gap to D6 CODEX_HOME.
  - _extractKeyFromDotenv has no direct unit test.
  - config.toml model selection mechanism (Vibe-specific quirk —
    no --model flag means OLP can't pass model per request). A D-later
    ADR note will discuss whether OLP should write a project-local
    ./.vibe/config.toml before spawn or accept the user-level config
    as authoritative.

Test count: 174 (after D6) → 222 (after D8).

Verification:
  node --check on all touched files: clean.
  npm test on Node 25.8.0: 222/222 pass in 210ms.
  STATIC_REGISTRY = [anthropic, openai, mistral] verified.
  hygiene grep: zero personal-name/path/token hits. Fixtures use
    <fake-mistral-api-key> placeholders.
