MCP server (5 fixes):
- Move semaphore acquisition inside goroutine so main loop stays
responsive when all slots are taken
- Add 10s write timeout to sendResponse to prevent pipe deadlock
when Claude Code pauses reading stdout
- Send fallback JSON-RPC error when json.Marshal fails instead of
silently swallowing the error and leaving caller waiting forever
- Silence unknown notification methods (req.ID == nil) instead of
sending unsolicited error responses that may desync the host
- Return MCP isError content for tool failures instead of top-level
JSON-RPC error, matching the MCP specification
Vector/embedding (3 fixes):
- Move EmbedBatchWithContext call before writeMu.Lock in AddDocuments
so ONNX inference runs outside the write lock
- Replace singleflight.Do with DoChan + ctx select in both
getOrComputeEmbedding and UnifiedSearch so callers can bail out
independently when their context expires
- Add activeQueries atomic counter; skip cache warming when user
queries are in-flight; reduce warming timeout from 5s to 2s
Hooks (4 fixes):
- Cap EnsureWorkerRunning to 15s hard deadline with context; reduce
StartupTimeout from 30s to 10s; reduce port-in-use retries
- Fix nil dereference panic in user-prompt hook when initResult is
nil (non-JSON worker response); use comma-ok assertions
- Use package-level hookClient/healthClient with DisableKeepAlives
to prevent FD leaks in short-lived hook processes
- Set SysProcAttr{Setpgid: true} to detach worker from hook process
group, preventing kill-cascade from Claude Code
Worker/DB (3 fixes):
- Replace os.Exit(0) in MCP config watcher with context cancellation
for clean protocol shutdown
- Add 60s context.WithTimeout around ProcessObservation calls in
processAllSessions to prevent hung CLI subprocesses from blocking
the queue processor forever
- Set explicit PRAGMA wal_autocheckpoint=1000 and add PASSIVE WAL
checkpoint to Optimize() to prevent checkpoint stalls
Adds 20+ regression tests across all fix areas.
