Track A (Infrastructure & Data Layer): - docker-compose.yml with all 7 services (nginx, frontend, api, mcp, renderer, worker, postgres, redis) - docker-compose.override.yml for local dev (hot reload, port exposure) - PostgreSQL init.sql with full schema (15 tables, pgvector indexes, creator economy stubs) - .env.example with all required environment variables Track A+B (API Layer): - FastAPI app with 10 routers (auth, shaders, feed, votes, generate, desires, users, payments, mcp_keys, health) - SQLAlchemy ORM models for all 15 tables - Pydantic schemas for all request/response types - JWT auth middleware (access + refresh tokens, Redis blocklist) - Redis rate limiting middleware - Celery worker config with job stubs (render, embed, generate, feed cache, expire bounties) - Alembic migration framework Service stubs: - MCP server (health endpoint, 501 for all tools) - Renderer service (Express + Puppeteer scaffold, 501 for /render) - Frontend (package.json with React/Vite/Three.js/TanStack/Tailwind deps) - Nginx reverse proxy config (/, /api, /mcp, /renders) Project: - DECISIONS.md with 11 recorded architectural decisions - README.md with architecture overview - Sample shader seed data (plasma, fractal noise, raymarched sphere)
