+- Month 3–4: Milestone 4
+- Month 5: Milestone 5
+- Month 6: Milestone 6
+- Months 7+: Milestone 7 and polish
+
+Risks & mitigations:
+- Third-party API rate limits — use queued workers and backoff.
+- OAuth complexity on mobile — use PKCE and server-side token exchange patterns.
+- Privacy/regulatory requirements — provide E2EE option and clear privacy policy.
+
+Deliverables created so far (as of 2025-08-29):
+- FastAPI backend with JWT auth, OIDC login with PKCE (multi-provider), RP-initiated logout, RBAC helpers, audit logging, and encrypted OAuth tokens
+- SQLAlchemy models and Alembic baseline; Makefile targets and scripts for migrations
+- CI: migration matrix (sqlite/postgres, Python 3.10–3.12), drift checks, and API smoke tests
+- Dockerfiles and docker-compose for local dev (backend + Postgres)
+- Tests (pytest) with green suite; this roadmap and basic README/CI badges
+- Integrations: Todoist and GitHub adapters with idempotent upserts, deletion/archive policy, and per-integration mapping table
+- Notifications & hooks: Notifier service (Slack, webhook, email transport: smtp/console/disabled) with health/test endpoints; hooks docs + schema/examples + server-side validation; pre/post sync hooks wired into worker lifecycle; frontend hooks editor
+- Background processing: Redis + RQ worker with retries/backoff, enqueue guard, provider-level concurrency caps, and periodic scheduler
+- Observability: Prometheus metrics, Grafana dashboard (including per-integration syncs, enqueue skips, queue depth, in-flight), structured logs; Promtail config for Loki; RQ queue length gauge (multi-queue)
+- Middleware: Redis-backed rate limiting; CSRF; security headers; request size limit
+- Migrations: Alembic revisions for IntegrationItemMap and richer Habit fields; CI drift guard
+- Admin endpoints: provider caps get/set (persisted), hooks schema and validate, orchestration summary, email health/test
+- Frontend: Integrations page with hooks editor (prefill + validation), provider caps editor, orchestration summary (manual refresh, auto-refresh timer, sorting)
+- Auth hardening: TOTP 2FA with recovery codes; session_alt cookie for admin-assisted 2FA; logout clears both primary and alt sessions
+- Public access: Public tokens for read-only widgets with hashing/verification and last-used tracking
+- DB migrations: Alembic revisions for public tokens, OIDC login state, and TOTP fields; helper scripts `scripts/db-upgrade.sh`, `scripts/db-stamp-head.sh`, and `scripts/alembic_check.py`
+- Frontend 2FA: minimal setup screen (QR + recovery codes + enable), route wiring and nav entry
+- Reliability: queue ping check and inline fallback when Redis is unavailable (tests updated accordingly)
+- Ops: Prometheus alerts pack and Promtail configuration checked in under `modern/ops/`
+ - Mobile: `modern/mobile/` Complete React Native app with Expo SDK 53; comprehensive UI with tab navigation; full habit management (create, edit, delete, complete); analytics dashboard with charts and metrics; achievement system with badges and progression; offline-first sync engine with change queue and conflict resolution; background sync with auto-retry; onboarding flow; OAuth authentication with secure token storage; comprehensive documentation and production-ready architecture
