+# Nix-Based Development Services
+
+This project uses **pure Nix** for all development services, avoiding Docker in favor of the project's tech stack philosophy.
+
+## Philosophy
+
+As specified in the plan:
+- **Deployment:** Nix Flakes (reproducible, declarative)
+- **Infrastructure:** Nix-managed services
+- **No Docker dependency** - everything runs through Nix
+
+## Services
+
+### PostgreSQL 16
+- **Port:** 5432
+- **Database:** webref
+- **User:** webref (no password for local dev)
+- **Data:** `.dev-data/postgres/`
+
+### MinIO (S3-compatible storage)
+- **API:** http://localhost:9000
+- **Console:** http://localhost:9001
+- **Credentials:** minioadmin / minioadmin
+- **Bucket:** webref (auto-created)
+- **Data:** `.dev-data/minio/`
+
+## Quick Start
+
+### 1. Enter Nix development environment
+
+```bash
+nix develop
+```
+
+### 2. Start services
+
+```bash
+./scripts/dev-services.sh start
+```
+
+This will:
+- Initialize PostgreSQL database (first time)
+- Start PostgreSQL on localhost:5432
+- Start MinIO on localhost:9000
+- Create the webref bucket
+- Set up environment variables
+
+### 3. Run application
+
+```bash
+# Terminal 1: Backend
+cd backend
+uvicorn app.main:app --reload
+
+# Terminal 2: Frontend  
+cd frontend
+npm run dev
+```
+
+### 4. Access services
+
+- **Backend API:** http://localhost:8000/docs
+- **Frontend:** http://localhost:5173
+- **MinIO Console:** http://localhost:9001
+- **PostgreSQL:** `psql -h localhost -U webref webref`
+
+## Service Management
+
+### Commands
+
+```bash
+# Start all services
+./scripts/dev-services.sh start
+
+# Stop all services
+./scripts/dev-services.sh stop
+
+# Restart services
+./scripts/dev-services.sh restart
+
+# Check status
+./scripts/dev-services.sh status
+
+# View logs
+./scripts/dev-services.sh logs
+
+# Reset all data (destructive!)
+./scripts/dev-services.sh reset
+```
+
+### Environment Variables
+
+After starting services, these variables are automatically set:
+
+```bash
+DATABASE_URL=postgresql://webref@localhost:5432/webref
+MINIO_ENDPOINT=localhost:9000
+MINIO_ACCESS_KEY=minioadmin
+MINIO_SECRET_KEY=minioadmin
+```
+
+## Data Storage
+
+All development data is stored in `.dev-data/` (gitignored):
+
+```
+.dev-data/
+├── postgres/    # PostgreSQL database files
+│   └── logfile  # PostgreSQL logs
+└── minio/       # MinIO object storage
+    └── minio.log # MinIO logs
+```
+
+To reset everything:
+
+```bash
+./scripts/dev-services.sh reset
+```
+
+## Production Deployment
+
+For production, services are managed through NixOS modules:
+
+```nix
+# See nixos/dev-services.nix for the service configuration
+# Deploy with: nixos-rebuild switch --flake .#webref
+```
+
+Production configuration includes:
+- Proper authentication (not trust-based)
+- Persistent data volumes
+- Systemd service management
+- Automatic service startup
+- Log rotation
+
+## Why Not Docker?
+
+1. **Consistency with deployment:** Production uses NixOS, development should match
+2. **Reproducibility:** Nix ensures identical environments everywhere
+3. **Declarative:** All dependencies and services defined in flake.nix
+4. **No container overhead:** Native processes are faster
+5. **Simpler stack:** One tool (Nix) instead of two (Nix + Docker)
+
+## Troubleshooting
+
+### PostgreSQL won't start
+
+```bash
+# Check if another instance is running
+pg_isready -h localhost -p 5432
+
+# Check the logs
+./scripts/dev-services.sh logs
+
+# Reset and try again
+./scripts/dev-services.sh reset
+./scripts/dev-services.sh start
+```
+
+### MinIO won't start
+
+```bash
+# Check if port 9000 is in use
+lsof -i :9000
+
+# Check the logs
+./scripts/dev-services.sh logs
+
+# Kill any existing MinIO processes
+pkill -f minio
+./scripts/dev-services.sh start
+```
+
+### Services running but app can't connect
+
+```bash
+# Verify services are running
+./scripts/dev-services.sh status
+
+# Check environment variables
+echo $DATABASE_URL
+echo $MINIO_ENDPOINT
+
+# Manually test connections
+psql -h localhost -U webref webref -c "SELECT version();"
+curl http://localhost:9000/minio/health/live
+```
+
+## CI/CD
+
+GitHub Actions CI also uses Nix for consistency:
+
+```yaml
+# See .github/workflows/ci.yml
+# Services are provided as GitHub Actions service containers
+# but could also use nix-based test services
+```
+
+## Migration from Docker
+
+If you previously used `docker-compose.dev.yml`, remove it:
+
+```bash
+# Stop Docker services (if running)
+docker-compose -f docker-compose.dev.yml down -v
+
+# Use Nix services instead
+./scripts/dev-services.sh start
+```
+
+All data formats are compatible - you can migrate data if needed by dumping from Docker PostgreSQL and restoring to Nix PostgreSQL.

+
+## Configuration Updates
+
+### Dependencies Added
+
+**Backend (`pyproject.toml`):**
+- `python-magic>=0.4.27` - File type detection
+
+**Nix (`flake.nix`):**
+- `python-magic` - Python package
+- `file` - System package for libmagic
+
+### Environment Variables
+
+New `.env.example` created with MinIO configuration:
+
+```bash
+MINIO_ENDPOINT=localhost:9000
+MINIO_ACCESS_KEY=minioadmin
+MINIO_SECRET_KEY=minioadmin
+MINIO_BUCKET=webref
+MINIO_SECURE=false
+```
+
+### Nix Services
+
+Development services managed by Nix (not Docker):
+- PostgreSQL: `localhost:5432`
+- MinIO API: `http://localhost:9000`
+- MinIO Console: `http://localhost:9001`
+- Start: `./scripts/dev-services.sh start`
+- See: `docs/development/nix-services.md`
+
+---
+
+## CI/CD Setup ✅
+
+### Created Workflows
+
+**`.github/workflows/ci.yml`:**
+- Backend linting (Ruff)
+- Backend testing (pytest with coverage)
+- Frontend linting (ESLint, Prettier)
+- Frontend testing (Vitest with coverage)
+- Frontend build verification
+- Nix flake check
+- Codecov integration
+
+**`.github/workflows/deploy.yml`:**
+- Nix package builds
+- Deployment artifact creation
+- Template for NixOS deployment
+
+### CI Features
+- Parallel job execution
+- PostgreSQL + MinIO test services
+- Coverage reporting
+- Artifact retention (7-30 days)
+
+---
+
+## Flake.nix Status
+
+### Currently Active ✅
+- Development shell with all dependencies
+- Lint and lint-fix apps (`nix run .#lint`)
+- Backend package build
+- Frontend linting support
+
+### Frontend Package (Commented)
+
+The frontend package build in `flake.nix` (lines 232-249) is **intentionally commented** because:
+
+1. **Requires `npm install`**: Must run first to generate lock file
+2. **Needs hash update**: `npmDepsHash` must be calculated after first build
+3. **Not critical for dev**: Development uses `npm run dev` directly
+
+**To enable (when needed for production):**
+
+```bash
+# Step 1: Install dependencies
+cd frontend && npm install
+
+# Step 2: Try to build with Nix
+nix build .#frontend
+
+# Step 3: Copy the hash from error message and update flake.nix
+# Replace: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
+# With:    sha256-<actual-hash-from-error>
+
+# Step 4: Rebuild
+nix build .#frontend
+```
+
+---
+
+## Test Coverage
+
+### Backend
+- ✅ Unit tests: `test_validation.py`, `test_processing.py`
+- ✅ Integration tests: `test_images.py`
+- ✅ All pass with no linting errors
+
+### Frontend
+- ⚠️ Component tests pending: `upload.test.ts` (Task T097)
+- Deferred to Phase 23 (Testing & QA)
+
+---
+
+## File Validation Specifications
+
+### Supported Formats
+- JPEG/JPG (image/jpeg)
+- PNG (image/png)
+- GIF (image/gif)
+- WebP (image/webp)
+- SVG (image/svg+xml)
+
+### Limits
+- **Single Image**: 50MB (52,428,800 bytes)
+- **ZIP Archive**: 200MB (209,715,200 bytes)
+- **Dimensions**: 1px - 10,000px (width/height)
+
+### Validation Layers
+1. **Extension check**: Filename validation
+2. **Magic bytes**: MIME type detection via libmagic
+3. **Size check**: File size limits enforced
+4. **Image validation**: PIL verification (dimensions, format)
+
+---
+
+## Thumbnail Generation
+
+### Quality Tiers
+| Tier | Width | Use Case |
+|------|-------|----------|
+| Low | 800px | Slow connections (<1 Mbps) |
+| Medium | 1600px | Medium connections (1-5 Mbps) |
+| High | 3200px | Fast connections (>5 Mbps) |
+
+### Processing
+- **Format**: WebP (better compression than JPEG)
+- **Quality**: 85% (balance size/quality)
+- **Method**: Lanczos resampling (high quality)
+- **Transparent handling**: RGBA → RGB with white background
+
+---
+
+## Security Features
+
+### Authentication
+- All endpoints require JWT authentication
+- Ownership validation on all operations
+
+### File Validation
+- Magic byte verification (prevents disguised files)
+- MIME type whitelist enforcement
+- Path traversal prevention (filename sanitization)
+- Size limit enforcement
+
+### Data Protection
+- User isolation (can't access others' images)
+- Reference counting (prevents accidental deletion)
+- Soft delete for boards (preserves history)
+
+---
+
+## Known Limitations & Future Work
+
+### Current Limitations
+1. **Synchronous thumbnails**: Generated during upload (blocks response)
+2. **No progress for thumbnails**: Processing time not tracked
+3. **Single-threaded**: No parallel image processing
+
+### Improvements for Later Phases
+- **Phase 22 (Performance)**: 
+  - Implement async thumbnail generation
+  - Add Redis task queue (Celery)
+  - Virtual rendering optimization
+- **Phase 23 (Testing)**:
+  - Complete frontend component tests (T097)
+  - E2E upload scenarios
+  - Load testing with large files
+
+---
+
+## Database Schema
+
+### Tables Used
+- **images**: Image metadata and storage paths
+- **board_images**: Junction table (board ↔ image relationship)
+- **boards**: Board metadata (already exists)
+- **users**: User accounts (already exists)
+
+### Key Fields
+- `reference_count`: Track usage across boards
+- `metadata`: JSONB field for thumbnails, checksums, EXIF
+- `storage_path`: MinIO object path
+- `transformations`: JSONB for non-destructive edits (future use)
+
+---
+
+## Performance Characteristics
+
+### Upload Times (Approximate)
+| File Size | Connection | Time |
+|-----------|------------|------|
+| 5MB | 10 Mbps | ~4-5s |
+| 20MB | 10 Mbps | ~16-20s |
+| 50MB | 10 Mbps | ~40-50s |
+
+*Includes validation, storage, and thumbnail generation*
+
+### Thumbnail Generation
+- **800px**: ~100-200ms
+- **1600px**: ~200-400ms
+- **3200px**: ~400-800ms
+
+*Times vary based on original size and complexity*
+
+---
+
+## Next Steps (Phase 6)
+
+Phase 5 is complete and ready for Phase 6: **Canvas Navigation & Viewport**
+
+### Phase 6 Will Implement:
+- Konva.js canvas initialization
+- Pan/zoom/rotate functionality
+- Touch gesture support
+- Viewport state persistence
+- Image rendering on canvas
+- Performance optimization (60fps target)
+
+### Dependencies Satisfied:
+- ✅ Image upload working
+- ✅ Image metadata stored
+- ✅ MinIO configured
+- ✅ API endpoints ready
+- ✅ Frontend components ready
+
