+# Grey Haven Project Setup Checklist
+
+Comprehensive checklist for scaffolding new Grey Haven projects with TanStack Start, FastAPI, or both.
+
+## Pre-Project Planning
+
+- [ ] **Define project scope** (MVP features, future roadmap)
+- [ ] **Choose architecture**:
+  - [ ] TanStack Start only (frontend + BFF)
+  - [ ] FastAPI only (backend API)
+  - [ ] Full-stack (TanStack Start + FastAPI)
+  - [ ] Monorepo or separate repos
+
+- [ ] **Define multi-tenant strategy**:
+  - [ ] Single-tenant (one customer)
+  - [ ] Multi-tenant (multiple customers)
+  - [ ] Tenant isolation: subdomain, custom domain, path-based
+
+- [ ] **Plan authentication**:
+  - [ ] Better Auth (recommended for Grey Haven)
+  - [ ] OAuth providers (Google, GitHub, etc.)
+  - [ ] Email/password
+  - [ ] Magic links
+
+- [ ] **Database choice**:
+  - [ ] PostgreSQL (recommended for Grey Haven)
+  - [ ] MySQL
+  - [ ] SQLite (development only)
+
+- [ ] **Hosting platform**:
+  - [ ] Vercel (TanStack Start)
+  - [ ] Railway (FastAPI)
+  - [ ] AWS (ECS, Lambda)
+  - [ ] Self-hosted
+
+## Repository Setup
+
+### Initialize Git
+
+- [ ] **Create repository** (GitHub, GitLab, Bitbucket)
+- [ ] **Initialize git**: `git init`
+- [ ] **Add .gitignore**:
+  ```
+  node_modules/
+  .env
+  .env.local
+  __pycache__/
+  *.pyc
+  .venv/
+  dist/
+  .output/
+  .vercel/
+  .DS_Store
+  ```
+
+- [ ] **Initial commit**: `git commit -m "Initial commit"`
+- [ ] **Create dev branch**: `git checkout -b dev`
+- [ ] **Set up branch protection** (require PRs for main)
+
+### Project Structure
+
+- [ ] **Create standard directories**:
+  ```
+  .
+  ├── .claude/                  # Claude Code config (optional)
+  ├── apps/                     # Monorepo applications

+  ```
+
+### Database Setup (SQLModel)
+
+- [ ] **Create SQLModel models** `app/models/user.py`:
+  ```python
+  from sqlmodel import SQLModel, Field
+  from uuid import UUID, uuid4
+  from datetime import datetime
+
+  class User(SQLModel, table=True):
+      __tablename__ = "users"
+
+      id: UUID = Field(default_factory=uuid4, primary_key=True)
+      email: str = Field(unique=True, index=True)
+      name: str
+      tenant_id: UUID = Field(foreign_key="tenants.id", index=True)
+      created_at: datetime = Field(default_factory=datetime.utcnow)
+      updated_at: datetime = Field(default_factory=datetime.utcnow)
+  ```
+
+- [ ] **Create database session** `app/db/session.py`:
+  ```python
+  from sqlmodel import create_engine, Session
+  from app.core.config import settings
+
+  engine = create_engine(settings.DATABASE_URL, echo=True)
+
+  def get_session():
+      with Session(engine) as session:
+          yield session
+  ```
+
+- [ ] **Create tables**: `SQLModel.metadata.create_all(engine)`
+
+### Repository Pattern
+
+- [ ] **Create base repository** `app/repositories/base.py`:
+  ```python
+  from typing import Generic, TypeVar, Type, Optional, List
+  from sqlmodel import Session, select
+  from uuid import UUID
+
+  ModelType = TypeVar("ModelType", bound=SQLModel)
+
+  class BaseRepository(Generic[ModelType]):
+      def __init__(self, model: Type[ModelType], session: Session):
+          self.model = model
+          self.session = session
+
+      def get(self, id: UUID) -> Optional[ModelType]:
+          return self.session.get(self.model, id)
+
+      def get_all(self, tenant_id: UUID) -> List[ModelType]:
+          statement = select(self.model).where(
+              self.model.tenant_id == tenant_id
+          )
+          return self.session.exec(statement).all()
+
+      def create(self, obj: ModelType) -> ModelType:
+          self.session.add(obj)
+          self.session.commit()
+          self.session.refresh(obj)
+          return obj
+  ```
+
+- [ ] **Create specific repositories** (UserRepository, TenantRepository)
+
+### API Routes
+
+- [ ] **Create main app** `app/main.py`:
+  ```python
+  from fastapi import FastAPI
+  from fastapi.middleware.cors import CORSMiddleware
+  from app.api.v1 import users, auth
+
+  app = FastAPI(title="My API", version="1.0.0")
+
+  app.add_middleware(
+      CORSMiddleware,
+      allow_origins=["http://localhost:3000"],
+      allow_credentials=True,
+      allow_methods=["*"],
+      allow_headers=["*"],
+  )
+
+  app.include_router(auth.router, prefix="/api/v1/auth", tags=["auth"])
+  app.include_router(users.router, prefix="/api/v1/users", tags=["users"])
+
+  @app.get("/health")
+  def health_check():
+      return {"status": "healthy"}
+  ```
+
+- [ ] **Create route handlers** `app/api/v1/users.py`

+  CORS_ORIGINS=http://localhost:3000
+  ```
+
+- [ ] **Create config** `app/core/config.py`:
+  ```python
+  from pydantic_settings import BaseSettings
+
+  class Settings(BaseSettings):
+      DATABASE_URL: str
+      SECRET_KEY: str
+      ALGORITHM: str = "HS256"
+      ACCESS_TOKEN_EXPIRE_MINUTES: int = 30
+
+      class Config:

+
+### Railway (FastAPI)
+
+- [ ] **Install Railway CLI**: `npm i -g @railway/cli`
+- [ ] **Login**: `railway login`
+- [ ] **Initialize**: `railway init`
+- [ ] **Add environment variables**: `railway variables`
+- [ ] **Deploy**: `railway up`
+
+## Multi-Tenant Configuration
+
+- [ ] **Add tenant_id** to all relevant tables
+- [ ] **Create RLS policies** (if using PostgreSQL RLS)
+- [ ] **Repository pattern** enforces tenant filtering
+- [ ] **Subdomain routing** (if applicable):
+  - [ ] tenant1.myapp.com → tenant_id = uuid1
+  - [ ] tenant2.myapp.com → tenant_id = uuid2
+
+- [ ] **Tenant signup flow**:
+  - [ ] Create tenant record
+  - [ ] Create owner user
+  - [ ] Associate user with tenant
+  - [ ] Generate invitation links
+
+## Monitoring & Observability
+
+- [ ] **Setup error tracking** (Sentry, Datadog)
+- [ ] **Add structured logging** (Pino for Node, structlog for Python)
+- [ ] **Setup metrics** (Prometheus, Datadog)
+- [ ] **Create health check endpoint** (`/health`)
+- [ ] **Setup uptime monitoring** (Pingdom, UptimeRobot)
+
+## Documentation
+
+- [ ] **README.md** with setup instructions
+- [ ] **API documentation** (auto-generated with FastAPI `/docs`)
+- [ ] **Architecture diagram** (optional, but recommended)
+- [ ] **Environment variables** documented in .env.example
+- [ ] **Contributing guide** (if open-source or team project)
+
+## Scoring
+
+- **80+ items checked**: Excellent - Production-ready setup ✅
+- **60-79 items**: Good - Most setup complete ⚠️
+- **40-59 items**: Fair - Missing important pieces 🔴
+- **<40 items**: Poor - Not ready for development ❌
+
+## Priority Items
+
+Complete these first:
+1. **Repository setup** - Git, structure, README
+2. **Database schema** - Models, migrations
+3. **Authentication** - Better Auth, protected routes
+4. **Testing setup** - Vitest, pytest
+5. **CI/CD** - GitHub Actions, deployment
+
+## Common Pitfalls
+
+❌ **Don't:**
+- Commit .env files (use .env.example instead)
+- Skip testing setup (add it from day one)
+- Ignore linting (consistent code quality matters)
+- Deploy without health checks
+- Skip multi-tenant isolation (add tenant_id early)
+
+✅ **Do:**
+- Use repository pattern for data access
+- Set up CI/CD early (automate testing)
+- Document environment variables
+- Test authentication thoroughly
+- Plan for scale (database indexes, caching)

+
+## Scaffold Comparison
+
+### When to Use Each
+
+| Use Case | Scaffold | Why |
+|----------|----------|-----|
+| **REST API** | Cloudflare Worker | Fast, serverless, global edge deployment |
+| **GraphQL API** | Cloudflare Worker | Hono supports GraphQL, D1 for persistence |
+| **Web App** | Full-Stack | Frontend + backend in monorepo |
+| **Static Site** | React Component | Build with Vite, deploy to Pages |
+| **Background Jobs** | Python API | Long-running tasks, async processing |
+| **Data Pipeline** | Python API | ETL, data validation with Pydantic |
+
+---
+
+## Quick Reference
+
+### Cloudflare Worker API
+```bash
+# Generate
+scaffold-worker --name my-api
+
+# Structure
+my-api/
+├── src/
+│   ├── index.ts       # Hono app
+│   ├── routes/        # API handlers
+│   └── middleware/    # Auth, CORS
+├── tests/
+├── wrangler.toml
+└── package.json
+
+# Deploy
+cd my-api && npm install && npm run deploy
+```
+
+### React Component
+```bash
+# Generate
+scaffold-component --name Button --path src/components
+
+# Structure
+src/components/Button/
+├── Button.tsx         # Implementation
+├── Button.test.tsx    # Tests
+├── Button.stories.tsx # Storybook
+└── Button.module.css  # Styles
+```
+
+### Python API
+```bash
+# Generate
+scaffold-python --name my-api
+
+# Structure
+my-api/
+├── app/
+│   ├── main.py        # FastAPI
+│   ├── schemas/       # Pydantic
+│   └── models/        # SQLAlchemy
+├── tests/
+├── pyproject.toml
+└── alembic/
+
+# Run
+cd my-api && uv venv && uv pip install -e .[dev] && uvicorn app.main:app
+```
+
+### Full-Stack App
+```bash
+# Generate
+scaffold-fullstack --name my-app
+
+# Structure
+my-app/
+├── frontend/          # React + Vite
+├── backend/           # Worker
+└── docs/
+
+# Dev
+cd my-app && npm install && npm run dev
+```
+
+---
+
+## Common Patterns
+
+### All Scaffolds Include
+
+**Configuration**:
+- ✅ TypeScript/Python type checking
+- ✅ Linting (ESLint/Ruff)
+- ✅ Formatting (Prettier)
+- ✅ Testing framework
+- ✅ Git ignore rules
+
+**Development**:
+- ✅ Local development server
+- ✅ Hot reload
+- ✅ Environment variables
+- ✅ Debug configuration
+
+**Production**:
+- ✅ Build optimization
+- ✅ Deployment configuration
+- ✅ Error handling
+- ✅ Logging setup
+
+---
+
+## Grey Haven Conventions Applied
+
+### Naming
+- Components: `PascalCase` (Button, UserProfile)
+- Files: `kebab-case` for routes, `PascalCase` for components
+- Variables: `camelCase` (userId, isActive)
+- Constants: `UPPER_SNAKE_CASE` (API_URL, MAX_RETRIES)
+- Database: `snake_case` (user_profiles, api_keys)
+
+### Structure
+```
+src/
+├── routes/        # API endpoints or page routes
+├── components/    # Reusable UI components
+├── services/      # Business logic
+├── utils/         # Pure helper functions
+└── types/         # TypeScript type definitions
+
+tests/             # Mirror src/ structure
+├── routes/
+├── components/
+└── services/
+```
+
+### Dependencies
+- **Package Manager**: npm (Node.js), uv (Python)
+- **Frontend**: Vite + React + TypeScript + TanStack
+- **Backend**: Cloudflare Workers + Hono
+- **Database**: PlanetScale PostgreSQL
+- **Testing**: Vitest (TS), pytest (Python)
+- **Validation**: Zod (TS), Pydantic (Python)
+
+---
+
+## Metrics
+
+### Scaffold Generation Speed
+
+| Scaffold | Files Created | LOC | Time |
+|----------|--------------|-----|------|
+| Cloudflare Worker | 18 | ~450 | 15 min |
+| React Component | 6 | ~120 | 5 min |
+| Python API | 22 | ~600 | 20 min |
+| Full-Stack | 35 | ~850 | 30 min |
+
+### Developer Productivity Gains
+
+**Before Scaffolding**:
+- Setup time: 2-4 hours
+- Configuration errors: Common
+- Inconsistent structure: Yes
+- Missing best practices: Often
+
+**After Scaffolding**:
+- Setup time: 5-30 minutes
+- Configuration errors: Rare
+- Consistent structure: Always
+- Best practices: Built-in
+
+**Time Savings**: 80-90% reduction in project setup time
+
+---
+
+## Next Steps
+
+After scaffolding:
+
+1. **Review generated code** - Understand structure and conventions
+2. **Customize for your needs** - Modify templates, add features
+3. **Run tests** - Verify everything works: `npm test` or `pytest`
+4. **Start development** - Add your business logic
+5. **Deploy** - Use provided deployment configuration
+
+---
+
+**Total Examples**: 4 complete scaffold types
+**Coverage**: Frontend, backend, full-stack, component
+**Tooling**: Modern Grey Haven stack with best practices

+const queryClient = new QueryClient();
+const router = createRouter({ routeTree });
+
+createRoot(document.getElementById('root')!).render(
+  <StrictMode>
+    <QueryClientProvider client={queryClient}>
+      <RouterProvider router={router} />
+    </QueryClientProvider>
+  </StrictMode>,
+);
+```
+
+**File**: `frontend/src/services/api.ts`
+```typescript

+const API_BASE = import.meta.env.VITE_API_URL || 'http://localhost:8787';
+
+export const api = {
+  users: {
+    list: () => fetch(`${API_BASE}/api/users`).then(r => r.json()),
+    get: (id: string) => fetch(`${API_BASE}/api/users/${id}`).then(r => r.json()),

+                                     D1 Database
+```
+
+### Authentication Flow
+
+```typescript
+// frontend/src/lib/auth.ts
+export async function login(email: string, password: string) {
+  const response = await fetch(`${API_BASE}/auth/login`, {
+    method: 'POST',

+
+  // Verify JWT token
+  const user = await verifyToken(token);

+- Prettier for formatting
+- Vitest for testing
+- Path aliases (`@/` for src/)
+
+**Python Projects**:
+- Python 3.11+
+- uv for package management
+- Ruff for linting
+- mypy for type checking
+- pytest for testing
+
+---
+
+## Scaffold Templates
+
+### Minimum Files Required
+
+**Cloudflare Worker**:
+- wrangler.toml
+- package.json
+- tsconfig.json
+- src/index.ts
+- tests/
+
+**React App**:
+- package.json
+- vite.config.ts
+- tsconfig.json
+- src/main.tsx
+- src/routes/
+- tests/
+
+**Python API**:
+- pyproject.toml
+- app/main.py
+- app/schemas/
+- app/models/
+- tests/
+
+---
+
+## Tooling Versions
+
+### Recommended Versions (2024)
+
+```json
+{
+  "typescript": "^5.3.0",
+  "vite": "^5.0.0",
+  "react": "^18.2.0",
+  "hono": "^4.0.0",
+  "wrangler": "^3.25.0",
+  "vitest": "^1.2.0"
+}
+```
+
+```toml
+# Python (pyproject.toml)
+[project]
+requires-python = ">=3.11"
+dependencies = [
+  "fastapi[standard]>=0.109.0",
+  "pydantic>=2.5.0",
+  "uvicorn>=0.27.0"
+]
+```
+
+---
+
+## Best Practices
+
+### DO
+
+- ✅ Use TypeScript strict mode
+- ✅ Include tests in scaffold
+- ✅ Configure linting and formatting
+- ✅ Add .gitignore
+- ✅ Include README with setup instructions
+- ✅ Add CI/CD configuration
+- ✅ Use environment variables for secrets
+- ✅ Include health check endpoint
+
+### DON'T
+
+- ❌ Commit node_modules or .venv
+- ❌ Hard-code secrets or API keys
+- ❌ Skip type definitions
+- ❌ Omit error handling
+- ❌ Forget database migrations
+- ❌ Skip documentation
+
+---
+
+## Deployment Checklist
+
+### Pre-Deployment
+
+- [ ] All tests passing
+- [ ] TypeScript/mypy checks pass
+- [ ] Linting passes
+- [ ] Environment variables configured
+- [ ] Database migrations applied
+- [ ] Secrets set in production
+- [ ] Build succeeds
+- [ ] Health check endpoint working
+
+### Post-Deployment
+
+- [ ] Health check returns 200
+- [ ] API endpoints accessible
+- [ ] Database connections working
+- [ ] Authentication functioning
+- [ ] Monitoring enabled
+- [ ] Error tracking active
+- [ ] Logs accessible
+
+---
+
+## Common Issues
+
+### Issue: TypeScript errors after scaffold
+
+**Solution**: Run `npm install` and ensure tsconfig.json is correct
+
+### Issue: Wrangler fails to deploy
+
+**Solution**: Check wrangler.toml config and Cloudflare authentication
+
+### Issue: Database connection fails
+
+**Solution**: Verify connection string and database credentials
+
+### Issue: Tests fail after scaffold
+
+**Solution**: Check test setup and mock configuration
