Nested combos (comboA lists comboB, comboC, …) now stay one slot each: the inner combo always runs as fallback to produce a single answer. Failed hops are no longer written to Details/usage, and streaming no longer inserts a 0-token placeholder row. - chat.js: comboStack cycle detection; nested combos forced to fallback; persistUsage="success-only" for combo hops - combo.js: discardResponse() cancels unused bodies (fusion timeout / fallback) so dropped streams fire onStreamComplete; getComboModelsFromData keeps nested names and honors enabled=false - requestDetail.js: tokensForDetail() canonicalizes Claude/Gemini usage; shouldPersistRequestDetail() skips streaming-start and non-success hops - streamingHandler.js: drop the 0-token streaming placeholder write - RequestDetailsTab.js: read Gemini/Claude token names; show "streaming" status in amber - tests: add combo-nested.test.js (13 cases) - gitignore: ignore local .vitest/ artifacts Co-authored-by: CommandCodeBot <noreply@commandcode.ai>
9Router Embeddings Tests
Unit tests for the /v1/embeddings endpoint implementation.
Setup
Install test dependencies from the tests/ directory:
cd tests/ && npm install
Running Tests
From the tests/ directory:

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
