WARELIKandCursor 9ab14e7714 fix(combo/fusion): flatten tool history in panel calls to prevent 503
Panel models in the fusion strategy must answer in prose. When the request
carried tools or prior tool_calls/tool messages, agentic panel models kept
emitting tool_calls instead of prose, so extractPanelText() returned empty
and the engine fell into the 503 "All fusion panel models failed" branch.

Panel fan-out now strips tools/tool_choice and flattens tool turns into
assistant prose (instead of dropping them), so panels keep the context but
cannot loop on tools. The judge still receives the unmodified history.

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
