AUTH-004 — Implementation Report
1. Updated Implementation Summary
AuthMiddleware enforces authentication presence and two-tier session timeouts (inactivity + absolute) on every portal request. RoleMiddleware guards portal paths by comparing the session's role_snapshot against the URL prefix. Session timeout helpers were added to Session.php. AuthService.php was extended with canonical timeout property accessors.

4. Conflict Resolution Verification
Check	Result
MiddlewarePipeline.php unchanged	✅
Router.php unchanged	✅
No colon-suffix parsing introduced	✅
No constructor injection added	✅
No CoupleRoleMiddleware / CrewRoleMiddleware / AdminRoleMiddleware created	✅

5. Acceptance Criteria Verification
Criterion	Status
Anonymous access blocked by AuthMiddleware → 302 /login	✅
Unauthorized roles blocked by RoleMiddleware → 403 Forbidden	✅
Inactivity timeout triggers redirect (manipulated last_active_at)	✅
Absolute timeout triggers redirect (manipulated login_at)	✅
Logger::warning() on timeout and role mismatch events	✅
No SQL in middleware	✅
6. Security Checklist Verification
Item	Status
AuthMiddleware blocks unauthenticated requests	✅
RoleMiddleware validates role_snapshot	✅
Timeout destruction: Session::destroy() → session_start() → Session::regenerate(false)	✅
Flash message written after session destruction (new anonymous session)	✅
No credentials logged	✅
Logger::warning() on auth failure and role mismatch	✅
ErrorHandler::renderForbidden() on role mismatch	✅
7. Definition of Done
 AuthMiddleware.php created — implements MiddlewareInterface, zero constructor args
 RoleMiddleware.php created — implements MiddlewareInterface, zero constructor args
 Session.php extended — 3 timeout helpers, frozen kernel exemption applied
 AuthService.php extended — timeout properties integrated
 php -l passes on all 4 files — No syntax errors detected
 No kernel files modified outside the approved exception (Session.php)

8. Proposed Git Commit Message
feat(auth): implement AUTH-004 middleware and session timeouts
- Add AuthMiddleware: authentication presence check, inactivity timeout
  (2h universal), absolute timeout (8h/12h/24h per role). Expired sessions
  are destroyed and redirected to /login with a flash error message.
- Add RoleMiddleware: infers required role from URL path prefix
  (/app/couple→couple, /app/crew→crew, /app/admin→super_admin).
  Role mismatch renders 403 via ErrorHandler::renderForbidden().
- Extend Session.php: isInactivityExpired(), isAbsoluteExpired(), touch()
  helpers consumed by AuthMiddleware on every authenticated request.
- Extend AuthService.php: getAbsoluteTimeout() and getInactivityTimeout()
  make AuthService the canonical source for timeout config in Auth module.
Conflict: Router docblock showed 'RoleMiddleware:couple' colon-suffix
notation (non-normative). MiddlewarePipeline frozen. Role inference
from path prefix approved as resolution. Documented in RoleMiddleware
docblock and docs/ai/memory/33_AUTH004_conflict.md. DRP required for
parameterized middleware support.
Closes AUTH-004 | Sprint 2
(Do NOT execute — for Human Approver review only)

9. Documentation Deviations
Deviation	Impact
RoleMiddleware uses path-prefix role inference instead of constructor-injected role parameter	Functional equivalent for all current portal paths. No runtime difference. Parameterized middleware requires a future DRP.
10. Dependency Verification
Dependency	Status
AUTH-001 committed	✅ commit 50e9b19
AUTH-002 committed	✅ commit 499f8c2
Working tree clean (pre-implementation)	✅ verified
Sprint 0 kernel unchanged	✅ only Session.php modified (approved exemption)
Sprint 1 utilities unchanged	✅
MiddlewarePipeline.php frozen	✅ untouched
Router.php frozen	✅ untouched
AUTH-004 implementation is complete. Awaiting Human Approver review and commit authorization. Do NOT proceed to AUTH-003.
