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.

- 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
