fix(codex): durable OAuth refresh lifecycle
...
Add shared OAuth credential lifecycle manager with provider-aware refresh
decisions. Implement CodexExecutor.refreshCredentials so 401/403 retry
refresh works for Codex, track lastRefreshAt and refresh before the
upstream stale-token window, preserve omitted idToken, and add
per-connection single-flight refresh to avoid refresh-token rotation races.
Merged from PR #1664 .

feat: add /v1/embeddings endpoint (OpenAI-compatible) ( #146 )
...
* feat: implement /v1/embeddings endpoint (#117 )
Add OpenAI-compatible POST /v1/embeddings endpoint that routes through
the existing provider credential + fallback infrastructure.
Changes:
- open-sse/handlers/embeddingsCore.js: core handler (handleEmbeddingsCore)
* Validates input (string or array), encoding_format
* Builds provider-specific URL and headers for openai, openrouter,
and openai-compatible providers
* Handles 401/403 token refresh via executor.refreshCredentials
* Returns normalized OpenAI-format response { object: 'list', data, model, usage }
- cloud/src/handlers/embeddings.js: cloud Worker handler (handleEmbeddings)
* Auth + machineId resolution identical to handleChat
* Provider credential fallback loop with rate-limit tracking
- cloud/src/index.js: wire new routes
* POST /v1/embeddings (new format — machineId from API key)
* POST /{machineId}/v1/embeddings (old format — machineId from URL)
* test: add unit tests for /v1/embeddings endpoint
- Setup vitest as test framework (tests/ directory)
- embeddingsCore.test.js (36 tests):
- buildEmbeddingsBody: single string, array, encoding_format, default float
- buildEmbeddingsUrl: openai, openrouter, openai-compatible-*, unsupported
- buildEmbeddingsHeaders: per-provider headers, accessToken fallback
- handleEmbeddingsCore: input validation, success path, provider errors,
network errors, invalid JSON, token refresh 401 handling
- embeddings.cloud.test.js (23 tests):
- CORS OPTIONS preflight
- Auth: missing/invalid/old-format/wrong key → 401/400
- Body validation: bad JSON, missing model, missing input, bad model → 400
- Happy path: single string, array, delegation, CORS header, machineId override
- Rate limiting: all-rate-limited → 429 + Retry-After, no credentials → 400
- Error propagation: non-fallback errors, 429 exhausts accounts
Total: 59/59 tests passing
Framework: vitest v4.0.18, Node v22.22.0
* feat: add Next.js API route for /v1/embeddings endpoint
Wire the embeddings handler into Next.js App Router.
- src/app/api/v1/embeddings/route.js: Next.js API route (POST + OPTIONS)
- src/sse/handlers/embeddings.js: SSE-layer handler mirroring chat.js pattern
Uses handleEmbeddingsCore from open-sse/handlers/embeddingsCore.js with
the same auth, credential fallback, and token refresh logic as the chat
handler. Supports REQUIRE_API_KEY env var, provider fallback loop, and
consistent logging.
