BREAKING CHANGE: the Go module path is now github.com/tiennm99/tiennm99bot,
the default sticker pack is stickers_by_<bot username>, and the health body,
deploy DM, User-Agents and image names say tiennm99bot.
Rename:
- Go module github.com/tiennm99/miti99bot-go → github.com/tiennm99/miti99bot
- CloudFormation stack miti99bot-aws-port → miti99bot
- Drop "port", "Cloud Run", "GCP", "cutover", "Phase NN" framing from
active code and docs — project reads as canonical AWS-Lambda from now on.
AWS deploy guide + flow fix:
- New docs/deploy-aws-free-tier-guide.md — Ubuntu 24.04 ARM64 onboarding
with project-local venv (pip awscli + sam-cli), SSM secrets via read -s,
idempotent OIDC provider + role creation, $1 budget alarm.
- Drop sam build from the pipeline — provided.al2023 + makefile builder
expects a Makefile in CodeUri (build/lambda/, the output dir), so the
step always fails. sam deploy --template-file template.yaml now reads
the raw template and zips build/lambda/ directly.
- Rollback section rewritten — use continue-update-rollback /
cancel-update-stack / git-SHA redeploy. Drop the broken
--use-previous-template recipe.
- DynamoDB free-tier row corrected (on-demand is 2.5M read / 1M write
request units, not 25 RCU/WCU).
Updated:
- README.md fully rewritten (drops port/legacy framing, lists modules,
points new users at the free-tier guide).
- aws/README.md retitled "AWS account setup", phase numbers stripped.
- Makefile / .github/workflows/deploy.yml — sam deploy flow.
- samconfig.toml — stack_name = "miti99bot".
- Go comments — Cloud Run → Lambda, Cloud Scheduler → EventBridge
Scheduler, Cloud Logging → CloudWatch Logs.
- Struct field GCPProject → FirestoreProject (env GOOGLE_CLOUD_PROJECT
unchanged).
Plus advisory reports under plans/reports/ from the code-reviewer +
researcher passes that informed the fixes.
Verified: go vet ./..., go build ./..., go test ./... all green.
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).
