Add reverse-IPC protocol support: Rust runtime can send intercept_llm
requests to cowork-service, which routes them through @bytelyst/llm-router.
Changes:
- ipc-bridge.ts: handleLine now detects incoming requests (has 'method' field)
vs normal responses. New handleIncoming() + sendResponse() for reverse IPC.
New onIncomingRequest() to register the handler.
- server.ts: Wires intercept_llm handler — validates messages, calls
getLlmRouter().chat(), records spend for budget tracking, logs provider/model.
- ipc-bridge.test.ts: 5 new tests for reverse IPC (handler registration,
routing, error handling, request vs response disambiguation).
- server.test.ts: Updated IPC bridge mock with onIncomingRequest.
Test count: 85 (was 80)
Add usage query routes to cowork-service that proxy to platform-service:
- GET /api/usage/summary — user's aggregated usage with days filter
- POST /api/usage/check-limits — check if user is within plan limits
- modules/usage/types.ts — UsageSummaryQuerySchema, CheckLimitsSchema (Zod)
- modules/usage/routes.ts — proxy routes with error handling
- server.ts — register usageRoutes (5 route modules total)
- server.test.ts — add usage routes mock, update register count to 5
57 tests passing, 9 test files, typecheck clean
Bug fixes from systematic review of H.7 LLM router wiring:
- lib/llm-router.ts: remove RUST_RUNTIME_TIMEOUT_MS (300s IPC timeout) override
— let LlmRouter use its built-in 30s default, appropriate for cloud API calls
- server.test.ts: add debug/error to appMock.log — prevents fragile failures
if any startup path hits those log levels
- server.test.ts: add OLLAMA_URL + OLLAMA_MODELS to config mock
New feature:
- config.ts: add OLLAMA_URL + OLLAMA_MODELS env vars for local Ollama support
- server.ts: wire Ollama env vars into initLlmRouter() — set
OLLAMA_MODELS=model1,model2 to auto-add local Ollama as a provider
57 tests passing, 9 test files, typecheck clean
Added LLM routing module to cowork-service:
- lib/llm-router.ts — singleton LlmRouter with cloud + local Ollama support
- modules/llm/types.ts — Zod request schemas
- modules/llm/routes.ts — POST /api/llm/chat, GET /api/llm/providers, GET /api/llm/health
- All endpoints gated by llm_multi_model_enabled feature flag
- Best-effort init: service works without API keys (router stays uninitialized)
- 8 new tests (routes), server test updated for 3 route modules
- 57 total tests passing, typecheck clean
