Initial scaffold: FocusFlow ADHD Task Manager backend
Dart Shelf API with modules: auth (JWT + PBKDF2), tasks (CRUD + dopamine scorer), streaks (forgiveness + freeze), rewards (variable reward engine), time perception, sync (offline-first push/pull), rooms (body doubling placeholder). Includes DB migration (001_initial_schema.sql) and Docker Compose. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
