- Add LogoutHandler: deletes session row (D-06), clears cookie, redirects to /login
- Protect GET / inside RequireAuth group; remove old top-level registration
- Add POST /logout inside same RequireAuth group (D-22: POST-only logout)
- Update Layout signature to accept *auth.User; render logout form + email when authed
- Update Index template to accept *auth.User and show "Signed in as {email}"
- Update SignupPage/LoginPage to pass nil to Layout (auth pages are unauthed)
- Update IndexHandler to pull user from auth.Authed(ctx) and pass to template
- Update TestIndex_RendersHxGet -> TestIndex_UnauthRedirects (GET / now protected)
- AUTH-04 (logout) and AUTH-05 (protected /) are now closed
- templates/layout.templ: base HTML shell per UI-SPEC §Base Layout Contract
(max-w-5xl container, slate-50 header, slate-200 borders, footer copy,
/static/tailwind.css in <head>, /static/htmx.min.js deferred at body end —
D-10: HTMX never loaded from a CDN)
- templates/index.templ: root page consuming @ui.Card and @ui.Button for the
canonical HTMX demo (UI-SPEC §Component Library Contract canonical block)
- templates/fragments.templ: TimeFragment renders <span> with RFC3339 UTC
timestamp; templ auto-escapes interpolation (T-01-13)
- internal/web/handlers.go: HealthzHandler (200 ok / 503 degraded per D-20,
2s Ping timeout), IndexHandler, DemoTimeHandler with injected clock
- internal/web/router.go: Pinger interface; NewRouter wires
RequestIDMiddleware → RealIP → SlogLoggerMiddleware → Recoverer (D-08
+ Pitfall 6 — chi middleware.Logger deliberately NOT registered) and
routes /, /healthz, /demo/time, /static/* via http.FileServer (T-01-08
path traversal blocked by http.Dir)
All six handler tests + ui package tests are GREEN under default go test.
