luulam e438a03f96 feat(open-sse): early-peek stream error detection + fix UTF-8 loss in CommandCode peek
- new open-sse/utils/streamErrorPeek.js: bounded peek of the first bytes of a
  200 stream; configured pattern match → 502 so account/combo fallback can run
  before any byte reaches the client (streaming included). Re-emits RAW bytes
  so split multi-byte UTF-8 sequences survive the peek (never re-encode
  decoded text — TextDecoder flush corrupts a lone leading byte to U+FFFD).
- chatCore: run the peek after executor.execute when the provider has
  streamErrorPatterns configured; chat.js passes the settings through.
- commandcode executor: same raw-bytes fix in peekForUpstreamError + regression
  test that fails against the old flush-based re-encode.

9Router Embeddings Tests

Unit tests for the /v1/embeddings endpoint implementation.

Setup

Vitest must be installed globally or in /tmp/node_modules (due to npm workspace hoisting from the root Next.js project):

cd /tmp && npm install vitest

Running Tests

cd tests/
NODE_PATH=/tmp/node_modules /tmp/node_modules/.bin/vitest run --reporter=verbose --config ./vitest.config.js

Or using the package script (from the tests/ directory):

npm test

Test Files

File What it tests
unit/embeddingsCore.test.js open-sse/handlers/embeddingsCore.js — core logic: body builder, URL router, headers, handler flow
unit/embeddings.cloud.test.js cloud/src/handlers/embeddings.js — cloud worker handler: auth, validation, rate limits, CORS

Coverage Summary (59 tests)

embeddingsCore.test.js (36 tests)

  • buildEmbeddingsBody: single string, array, encoding_format, default float
  • buildEmbeddingsUrl: openai, openrouter, openai-compatible-*, unsupported providers
  • buildEmbeddingsHeaders: per-provider header sets, fallback to accessToken
  • handleEmbeddingsCore input validation: missing, wrong type, null, empty
  • handleEmbeddingsCore success: response format, CORS, Content-Type, callbacks
  • handleEmbeddingsCore errors: 400/429/500, network error, invalid JSON
  • handleEmbeddingsCore token refresh: 401 retry, graceful fallback

embeddings.cloud.test.js (23 tests)

  • CORS OPTIONS: 200 response, empty body, correct headers
  • Authentication: missing key, bad format, old-format key, wrong key value, valid key
  • Body validation: invalid JSON, missing model, missing input, bad model
  • Happy path: single string, array, correct delegation, CORS header, machineId override
  • Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
  • Error propagation: non-fallback errors passed through, 429 exhausts accounts
  • machineId override: validates key, rejects wrong key
