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.

- OpenAI /v1/chat/completions stream=true (server-sent events,
  data: {chunk} per delta, terminator data: [DONE])

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) c175e8994c feat(phase-1): land Anthropic provider plugin (D4)
Phase 1 Day 2. Anthropic provider plugin code lands, plus contractVersion
field added across base.mjs and validated strictly. Anthropic stays
CANDIDATE per ALIGNMENT.md Provider Inventory — D5 flips to Enabled after
the real spawn E2E audit passes. POST /v1/chat/completions claude-* still
returns 503 until then.

Files:
  NEW:  lib/providers/anthropic.mjs (445 lines)
  MOD:  lib/providers/base.mjs (+8 lines — contractVersion enforcement)
  MOD:  lib/providers/index.mjs (+37 lines — STATIC_REGISTRY adds anthropic
        + getProviderByName helper)
  MOD:  models-registry.json — populates providers.anthropic with 3 models
        opus-4-7 / sonnet-4-6 / haiku-4-5, alias map, candidate marker
  MOD:  test-features.mjs (+481 lines — Suite 6: 37 new tests covering
        contract conformance, contractVersion enforcement, IR translation,
        mock-spawn behaviour, healthCheck, estimateCost)

Authority citations (all verified by independent reviewer against actual
OCP byte offsets):
  Spawn pattern: OCP server.mjs:542 stdio shape, port verbatim.
  CLI args: OCP server.mjs:384-414 buildCliArgs pattern — -p, --model X,
    --output-format text, --no-session-persistence (session-resume and
    permissions branches stripped per OLP no-state architecture).
  stdin write: OCP server.mjs:586-587 verbatim.
  Stdout text handling: OCP server.mjs:735-748 raw d.toString per chunk
    no JSON envelope, matches --output-format text.
  Auth chain: OCP server.mjs:864-888 (env CLAUDE_CODE_OAUTH_TOKEN ->
    ~/.claude/.credentials.json -> macOS keychain with both label formats
    "claude-code-credentials" and "Claude Code-credentials") ported in
    same priority order. One delta vs OCP: OLP guards keychain branch on
    process.platform === darwin, OCP relies on try/catch on Linux. Both
    behave identically; OLP avoids an unnecessary shell-out.
  Env cleanup: OCP server.mjs:530-534 — delete CLAUDECODE, ANTHROPIC_
    API_KEY, ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN. CLAUDECODE
    clobbering pitfall inherited per memory.

Architectural decisions:
  1. Anthropic stays Candidate at D4. STATIC_REGISTRY.length === 1 but
     loadProviders({}) returns empty Map. Suite 7 HTTP integration tests
     continue to verify 503 with no_enabled_provider for any claude-*
     model. D5 changes the config default to enable: { anthropic: true }
     and adds the real E2E spawn test.
  2. contractVersion === 1.0 strictly enforced (F3 fold-in from D3
     review). validateProvider in base.mjs rejects providers missing or
     having any other version string. Suite 6 includes 4 tests covering
     missing / 0.9 / 1.0 / undefined cases.
  3. quotaStatus returns null at D4 with a TODO comment pointing at the
     ALIGNMENT.md 2026-06-16 one-shot audit. Anthropic Agent SDK Credit
     pool balance API has not been pinned; verification scheduled for
     2026-06-16 per OLP one-shot audits.
  4. estimateCost returns shape but usd: null. Per-million-token rates
     not pinned at D4. Lands when models-registry.json gains a pricing
     field in a later phase.
  5. Lossy translations explicitly documented in anthropic.mjs file
     header per ADR 0003 § Lossy-translation documentation requirement.
     Includes response_format json_object (system-prompt augmented),
     top_p (no --top-p flag), tool_choice required (no flag), and
     request-level tools[] + assistant tool_calls + tool_call_id
     (text-in/text-out CLI cannot consume structured tool wire format).
     The tools[] documentation gap was a reviewer non-blocking finding;
     folded in this commit.

Mocking discipline: no real claude -p spawn in any D4 test. spawn-path
coverage uses __setSpawnImpl injection of fake child_process. No real
OAuth tokens or API keys in fixtures — all use placeholder strings
fake-oauth-token / fake-token. Auth path computed via
path.join(homedir(), .claude, .credentials.json), no hardcoded
/Users/<name> literal.

Reviewer chain (Iron Rule 10):
  Implementer: sonnet (general-purpose).
  Fresh-context reviewer: opus (ecc:code-reviewer). Verdict
    APPROVE_WITH_MINOR.
  Reviewer ran npm test (98/98 pass) and verified all five OCP citations
    at the actual byte offsets in /Users/taodeng/ocp/server.mjs. All
    citations confirmed accurate.

Reviewer non-blocking findings:
  1. tools[] and tool_calls lossy-translation undocumented — FOLDED IN
     this commit (anthropic.mjs header rewritten with full lossy list).
  2. with type json import attribute Node 20 compat — DEFERRED to CI
     verification. The syntax is stable on Node 20.10+ and the CI
     setup-node@v4 with node-version 20 resolves to latest 20.x. If
     CI Node 20 leg fails, mitigation is bump engines.node to >=20.10
     or swap both import-attribute lines for readFileSync + JSON.parse.
  3. CLI_NOT_FOUND error code declared but never thrown — DEFERRED to
     a future commit. Pure cosmetic; could distinguish ENOENT from
     generic spawn errors but no functional impact.

Test count: 61 -> 98 (+37 D4 tests).

Verification:
  node --check on all touched files: clean.
  npm test on Node 25.8.0: 98/98 pass in 209ms.
  Reviewer-run npm test independently: 98/98 pass.
  loadProviders({}) returns empty Map (verified by orchestrator and
    reviewer): Anthropic Candidate gate holds.
  hygiene grep: no personal names, no /Users/<name>/ literals, no real
    OAuth tokens or API keys.
