## 🎯 Design Principles Met

### From CLAUDE.md
- ✅ **Conciseness**: Functions 5-40 lines, single responsibility
- ✅ **No Hacks**: Explicit `NotImplementedError` for TODOs
- ✅ **Separation of Concerns**: Clear module boundaries
- ✅ **Modularity**: Small, focused files (< 200 lines each)
- ✅ **Type Hints**: 100% coverage with Pydantic models
- ✅ **Error Handling**: Explicit errors, no silent failures

### From Percolate Philosophy
- ✅ **Privacy-First**: Tenant scoping throughout
- ✅ **Mobile-First**: Device flow with Ed25519 keys
- ✅ **Portable Intelligence**: Agent-lets as JSON schemas
- ✅ **Offline-Capable**: JWT verification with local keys
- ✅ **Rust/Python Boundary**: Clear separation maintained

## 🚀 Next Steps

### High Priority
1. **Settings Module** - Create `src/percolate/settings.py`
   - Base URLs (auth, API)
   - TTL values (access token, refresh token, device code)
   - Issuer/audience for JWT
   - OpenTelemetry configuration

2. **Storage Layer** - RocksDB integration
   - Device storage
   - Token storage
   - Pending authorization (KV with TTL)

3. **Example Agent-let** - Create `schema/agentlets/researcher.json`
   - Test schema structure
   - Validate registry loading

4. **MCP Client** - Implement tool attachment
   - Connect to MCP servers
   - Dynamic tool registration
   - Test with Pydantic AI

### Medium Priority
5. **FastAPI Application** - Create `src/percolate/api/main.py`
   - OAuth router
   - MCP router
   - Agent execution router
   - Health/status endpoints

6. **REM Memory Integration**
   - Implement MCP tools (search, entity, parse)
   - Connect to Rust memory engine

7. **OpenTelemetry Setup** - Create `src/percolate/otel/`
   - Tracer initialization
   - FastAPI instrumentation
   - Loguru bridge

### Low Priority
8. **CLI Commands** - Expand `src/percolate/cli/`
   - Agent management commands
   - Auth/device commands
   - Status/health commands

9. **Documentation**
   - API documentation
   - Authentication flow diagrams
   - Deployment guides

# Run tests
uv run pytest tests/test_imports.py -v

# Check types
uv run mypy src/percolate --ignore-missing-imports

# Format code
uv run black src/percolate tests

# Lint code
uv run ruff check src/percolate tests

# Start Python REPL with imports
uv run ipython
>>> from percolate.agents.context import AgentContext
>>> from percolate.auth.jwt_manager import JWTKeyManager
>>> from percolate.mcp.server import create_mcp_server
```

## 📝 Notes

### Pattern Adaptations
- **From Carrier**: Agent schema structure, Pydantic AI factory, MCP tool registration
- **From P8FS**: Device trust levels, ES256 JWT, device flow, FastAPI middleware

### Intentional Exclusions
- ❌ OIDC/Google auth (not needed for self-hosted)
- ❌ TiKV-specific storage (using RocksDB instead)
- ❌ Email verification flows (simplified for mobile-first)
- ❌ python-jose (redundant with PyJWT)

### Key Design Decisions
1. **Tenant-first**: All operations require `tenant_id`
2. **ES256 over RS256**: Smaller JWT signatures
3. **Device flow**: QR codes for mobile-first auth
4. **Explicit stubs**: `NotImplementedError` with TODOs
5. **Timezone-aware**: Modern `datetime.now(timezone.utc)`

1. Settings configuration
2. Storage layer integration
3. FastAPI application setup
4. REM memory integration

**Status**: 🟢 READY TO BUILD
