- 10 models: tenants, users, user_tenants, roles, sessions, audit_log, deletion_log, notifications, password_reset_tokens, api_tokens - Session-based auth (Redis + PostgreSQL audit trail) - Multi-tenant with ORM-level filtering + PostgreSQL RLS (set_config) - RBAC with roles/permissions + field-level permissions - CSRF protection via Origin header validation - Auth rate limiting (Redis counters with TTL) - CORS with explicit origins (no wildcard) - Health endpoint (no auth required) - Notification service + audit log middleware - 29 tests, 26 ACs, all passing - Coverage: 62% (infrastructure modules pending coverage in later tasks)
