- Add handlers_tasks.go: TasksDeps, TaskNewFormHandler, TaskCancelNewHandler, TaskCreateHandler, TaskShowHandler, TaskDeleteConfirmHandler, TaskDeleteHandler, plus stub Edit/Update/Reorder handlers
- Add task routes to router.go (static before parametric per Pitfall 1)
- Add TasksDeps param to NewRouter; update main.go and all test callers
- Move TaskColumns/TaskColumnLabels to templates package to avoid import cycle
- auth_login.templ: LoginPage + LoginFormFragment (mirrors signup shape)
- LoginForm + LoginErrors types added to templates/auth_forms.go
- LoginPageHandler + LoginPostHandler in handlers_auth.go
- Rate-limit check before user lookup (D-16, T-2-14)
- Single errInvalidCreds constant for D-20 enumeration defense
- Session rotation via Store.Rotate on success (D-10, T-2-04)
- HTMX-aware redirect and fragment responses (D-19, D-21)
- AuthDeps extended with Limiter *auth.LimiterStore field
- router.go: GET /login in RedirectIfAuthed group (D-23)
- main.go: LimiterStore created with janitor goroutine (D-16)
- Export NewLimiterStoreWithClock + SetLimiterClock for cross-package tests
- 12 TestLogin_* integration tests all pass with real DB
- Opens pgxpool from DATABASE_URL, logs 'worker ready', blocks on
SIGINT/SIGTERM, closes pool, exits 0
- Reuses web.NewSlogHandler — pure helper, no HTTP coupling
- No job queue libraries (river/asynq/pg_notify) — Phase 6 replaces this
file in full
- 48 lines (under 80-line budget signals 'we did not implement Phase 6
by accident')
- Reads DATABASE_URL (required), PORT (default 8080), ENV (default
development) from os.Getenv only — no third-party env loader (D-15:
.env exported by just dev, prod injects real env)
- slog.SetDefault wired before fatal-on-missing-DSN so even startup errors
emit structured output; sanitization per T-01-12 (never log DSN)
- pgxpool opened via db.NewPool; chi router mounted with ./static as the
asset root
- http.Server: ReadTimeout=15s, WriteTimeout=15s, IdleTimeout=60s
(T-01-10 slow-client mitigation)
- signal.NotifyContext (Go 1.21+) traps SIGINT/SIGTERM, propagates through
ctx; on signal: srv.Shutdown with 10s timeout, then explicit pool.Close
(Pitfall 4 — never via defer)
- No /readyz route (Phase 7 scope)
