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.
