alvis 65218762be feat: Phase 0 walking skeleton — monorepo, API, web, ML stub
Sets up the full Phase 0 foundation:

- pnpm workspaces + turbo build graph; native module build approval
- packages/shared-types: HTTP contracts (Tip, Auth, Integrations, User)
- services/api: Express modular monolith with better-sqlite3/drizzle
  - auth: Google OAuth2 + PKCE via openid-client v6, cookie sessions
  - integrations: Todoist OAuth2 connect/disconnect, token vault
  - recommender: RandomPolicy over Todoist tasks, feedback sink
  - user: profile, consent capture, full account deletion (GDPR)
- apps/web: Next.js 15, three pages (sign-in → connect → tip)
  - tip page: black canvas, hold-to-act gesture, action sheet
  - PWA manifest + theme
- ml/serving: FastAPI stub implementing the POST /score contract
- infra: docker-compose (core/full profiles), Dockerfiles, CI skeleton
- .env.example with all required vars documented

ml/

Python. Owns models, features, training, online scoring.

Dir Role Phase
serving/ FastAPI online scorer (/score), called by recommender 1
features/ feature definitions + store adapter (Feast later) 1
pipelines/ batch feature + training DAGs (Prefect/Airflow) 4
registry/ MLflow-backed model registry integration 4
experiments/ A/B assignment + multi-armed bandit policies 4
notebooks/ research; never imported by production code

Principles

  • Every model has a model card in registry/ describing inputs, offline metrics, fairness checks, and rollout history.
  • Online inference must be stateless and < 50ms p99.
  • Training reads from the offline feature store; serving reads from the online feature store; definitions are shared (no train/serve skew).
  • Shadow deploys before any policy change that affects real users.
