- Add new modules: doantu, semantle, twentyq, ai (Gemini integration)
- Update module registry with new command registration
- Update tests and documentation for module system
- Update README with new module references
Phase 11 partial of the go-port-cloud-run plan. Code-side
observability hooks ready ahead of Phase 01 GCP rollout.
- internal/server/log_middleware.go: HTTP middleware that wraps the
router and emits {msg:"req", method, path, status, ms} per
request. statusRecorder defaults to 200 when the inner handler
doesn't call WriteHeader (Go writes 200 implicitly on first body
write). Wired into server.New so /, /webhook, /cron/* all log.
- internal/metrics/counters.go: in-memory Registry with
IncCommand/IncError/IncAI. Atomic Int64 per name + RWMutex on the
map; steady-state increments are mutex-free. Periodic Run flushes
via the project logger every 60s and one final flush on ctx done.
Empty flush is silent (no-noise default).
- Dispatcher instrumented: every command invocation calls
metrics.IncCommand; every handler error calls
metrics.IncError("handler-error"). Logger keeps the full error
detail; counters keep the rate.
- cmd/server/main.go: go metrics.Run(rootCtx) so the flush loop
cancels with SIGTERM and emits the trailing window before exit.
Test coverage: 12 new tests (7 metrics, 3 middleware, 2 default-
registry round-trip). go test -race -count=1 ./... clean
(20 packages); golangci-lint clean.
Soak / cold-start measurement / log-based metrics setup deferred to
post-deployment (Phase 01 prerequisite).
Implements Phases 02 (partial) and 03 of the go-port-cloud-run plan.
Introduces module framework with per-module KV prefix isolation,
health check endpoint, request timeout protection, and comprehensive
test coverage. Cloud Run deployment deferred to Phase 01.
Security hardening: constant-time secret comparison, cron auth bridge,
and secrets stripped from dependency environment exports. Includes
Dockerfile, GitHub CI workflow (vet + race + build), and integration
tests for module lifecycle.
