-## 🚀 Quick Start (One Command)
+## 🚀 Complete Deployment Workflow
 
+### **1️⃣ Clone & Setup**
 ```bash
-cd /srv/digiserver-v2
-bash deploy.sh
+# Copy the app folder from repository
+git clone <repository>
+cd digiserver-v2
+
+# Copy environment file and modify as needed
+cp .env.example .env
+
+# Edit .env with your configuration:
+nano .env
 ```
 
-This will:
-1. ✅ Start Docker containers
-2. ✅ Initialize database
-3. ✅ Run migrations
-4. ✅ Configure HTTPS
-5. ✅ Display access information
+**Configure in .env:**
+```env
+SECRET_KEY=your-secret-key-change-this
+ADMIN_USERNAME=admin
+ADMIN_PASSWORD=your-secure-password
+DOMAIN=your-domain.com
+EMAIL=admin@your-domain.com
+IP_ADDRESS=192.168.0.111
+```
+
+---
+
+### **2️⃣ Deploy via Script**
+```bash
+# Run the deployment script
+./deploy.sh
+```
+
+This automatically:
+1. ✅ Creates `data/` directories (instance, uploads, nginx-ssl, etc.)
+2. ✅ Copies nginx configs from repo root to `data/`
+3. ✅ Starts Docker containers
+4. ✅ Initializes database
+5. ✅ Runs all migrations
+6. ✅ Configures HTTPS with SSL certificates
+7. ✅ Displays access information
+
+**Output shows:**
+- Access URLs (HTTP/HTTPS)
+- Default credentials
+- Next steps for configuration
+
+---
+
+### **3️⃣ Network Migration (When Network Changes)**
+
+When moving the server to a different network with a new IP:
+
+```bash
+# Migrate to the new network IP
+./migrate_network.sh 10.55.150.160
+
+# Optional: with custom hostname
+./migrate_network.sh 10.55.150.160 digiserver-secured
+```
+
+This automatically:
+1. ✅ Regenerates SSL certificates for new IP
+2. ✅ Updates database HTTPS configuration
+3. ✅ Restarts nginx and app containers
+4. ✅ Verifies HTTPS connectivity
+
+---
+
+### **4️⃣ Normal Operations**
+
+**Restart containers:**
+```bash
+docker compose restart
+```
+
+**Stop containers:**
+```bash
+docker compose down
+```
+
+**View logs:**
+```bash
+docker compose logs -f
+```
+
+**View container status:**
+```bash
+docker compose ps
+```

+# Dockerfile vs init-data.sh Analysis
+
+**Date:** January 17, 2026
+
+## Current Architecture
+
+### Current Workflow
+```
+1. Run init-data.sh (on host)
+   ↓
+2. Copies app code → data/app/
+3. Docker build creates image
+4. Docker run mounts ./data:/app
+5. Container runs with host's data/ folder
+```
+
+### Current Docker Setup
+- **Dockerfile**: Copies code from build context to `/app` inside image
+- **docker-compose**: Mounts `./data:/app` **OVERRIDING** the Dockerfile copy
+- **Result**: Code in image is replaced by volume mount to host's `./data` folder
+
+---
+
+## Problem with Current Approach
+
+1. **Code Duplication**
+   - Code exists in: Host `./app/` folder
+   - Code copied to: Host `./data/app/` folder  
+   - Code in Docker image: Ignored/overridden
+
+2. **Extra Deployment Step**
+   - Must run `init-data.sh` before deployment
+   - Manual file copying required
+   - Room for sync errors
+
+3. **No Dockerfile Optimization**
+   - Dockerfile copies code but it's never used
+   - Volume mount replaces everything
+   - Wastes build time and image space
+
+---
+
+## Proposed Solution: Two Options
+
+### **Option 1: Use Dockerfile Copy (Recommended)** ✅
+
+**Change Dockerfile:**
+```dockerfile
+# Copy everything to /app inside image
+COPY . /app/
+
+# No need for volume mount - image contains all code
+```
+
+**Change docker-compose.yml:**
+```yaml
+volumes:
+  # REMOVE the ./data:/app volume mount
+  # Keep only data-specific mounts:
+  - ./data/instance:/app/instance      # Database
+  - ./data/uploads:/app/app/static/uploads  # User uploads
+```
+
+**Benefits:**
+- ✅ Single source of truth (Dockerfile)
+- ✅ Code is immutable in image
+- ✅ No init-data.sh needed
+- ✅ Faster deployment (no file copying)
+- ✅ Cleaner architecture
+- ✅ Can upgrade code by rebuilding image
+
+**Drawbacks:**
+- Code changes require docker-compose rebuild
+- Can't edit code in container (which is good for production)
+
+---
+
+### **Option 2: Keep Current (With Improvements)**
+
+**Keep:**
+- init-data.sh for copying code to data/
+- Volume mount at ./data:/app
+
+**Improve:**
+- Add validation that init-data.sh ran successfully
+- Check file sync status before starting app
+- Add automated sync on container restart
+
+**Benefits:**
+- ✅ Dev-friendly (can edit code, restart container)
+- ✅ Faster iteration during development
+
+**Drawbacks:**
+- ❌ Production anti-pattern (code changes without rebuild)
+- ❌ Extra deployment complexity
+- ❌ Manual init-data.sh step required
+
+---
+
+## Current Production Setup Evaluation
+
+**Current System:** Option 2 (with volume mount override)
+
+### Why This Setup Exists
+
+The current architecture with `./data:/app` volume mount suggests:
+1. **Development-focused** - Allows code editing and hot-reload
+2. **Host-based persistence** - All data on host machine
+3. **Easy backup** - Just backup the `./data/` folder
+
+### Is This Actually Used?
+
+- ✅ Code updates via `git pull` in `/app/` folder
+- ✅ Then `cp -r app/* data/app/` copies to running container
+- ✅ Allows live code updates without container rebuild
+
+---
+
+## Recommendation
+
+### For Production
+**Use Option 1 (Dockerfile-based):**
+- Build immutable images
+- No init-data.sh needed
+- Cleaner deployment pipeline
+- Better for CI/CD
+
+### For Development
+**Keep Option 2 (current approach):**
+- Code editing and hot-reload
+- Faster iteration
+
+---
+
+## Implementation Steps for Option 1
+
+### 1. **Update Dockerfile**
+```dockerfile
+# Instead of: COPY . .
+# Change docker-compose volume mount pattern
+```
+
+### 2. **Update docker-compose.yml**
+```yaml
+volumes:
+  # Remove: ./data:/app
+  # Keep only:
+  - ./data/instance:/app/instance
+  - ./data/uploads:/app/app/static/uploads
+```
+
+### 3. **Update deploy.sh**
+```bash
+# Remove: bash init-data.sh
+# Just build and run:
+docker-compose build
+docker-compose up -d
+```
+
+### 4. **Add Migration Path**
+```bash
+# For existing deployments:
+# Copy any instance/database data from data/instance to new location
+```
+
+---
+
+## Data Persistence Strategy (Post-Migration)
+
+```
+Current:                          After Option 1:
+./data/app/          (code)  →   /app/ (in image)
+./data/instance/     (db)    →   ./data/instance/ (volume mount)
+./data/uploads/      (files) →   ./data/uploads/ (volume mount)
+```
+
+---
+
+## Risk Assessment
+
+### Option 1 (Dockerfile-only)
+- **Risk Level:** LOW ✅
+- **Data Loss Risk:** NONE (instance & uploads still mounted)
+- **Rollback:** Can use old image tag
+
+### Option 2 (Current)
+- **Risk Level:** MEDIUM
+- **Data Loss Risk:** Manual copying errors
+- **Rollback:** Manual file restore
+
+---
+
+## Conclusion
+
+**Recommendation: Option 1 (Dockerfile-based)** for production deployment
+- Simpler architecture
+- Better practices
+- Faster deployment
+- Cleaner code management

+# Groups Feature - Archived
+
+**Status: ARCHIVED AND REMOVED ✅**
+
+**Archive Date:** January 17, 2026
+
+## What Was Done
+
+### 1. **Files Archived**
+- `/app/templates/groups/` → `/old_code_documentation/templates_groups/`
+- `/app/blueprints/groups.py` → `/old_code_documentation/blueprint_groups.py`
+
+### 2. **Code Removed**
+- Removed groups blueprint import from `app/app.py`
+- Removed groups blueprint registration from `register_blueprints()` function
+- Removed Group import from `app/blueprints/admin.py` (unused)
+- Removed Group import from `app/blueprints/api.py` (unused)
+- Commented out `/api/groups` endpoint in API
+
+### 3. **What Remained in Code**
+- **NOT removed:** Group model in `app/models/group.py`
+  - Kept for database backward compatibility
+  - No imports or references to it now
+  - Database table is orphaned but safe to keep
+  
+- **NOT removed:** `app/utils/group_player_management.py`
+  - Contains utility functions that may be referenced
+  - Can be archived later if confirmed unused
+
+## Summary
+
+✅ Groups feature is now completely **unavailable in the UI and app logic**
+✅ No routes, blueprints, or navigation links to groups
+✅ Application loads cleanly without groups
+✅ Database tables preserved for backward compatibility
+
+## Why Groups Was Removed
+
+1. **Functionality replaced by Playlists**
+   - Groups: "Organize content into categories"
+   - Playlists: "Organize content into collections assigned to players"
+
+2. **Never used in the current workflow**
+   - Dashboard: Players → Playlists → Content
+   - No mention of groups in any UI navigation
+   - Players have NO relationship to groups
+
+3. **Redundant architecture**
+   - Playlists provide superior functionality
+   - Players directly assign to playlists
+   - No need for intermediate grouping layer
+
+## Original Purpose (Deprecated)
+
+- Groups were designed to organize content
+- Could contain multiple content items
+- Players could be assigned to groups
+- **BUT:** Player model never implemented group relationship
+- **Result:** Feature was incomplete and unused
+
+## Current Workflow (Active) ✅
+
+```
+1. Create Playlist (organize content)
+2. Upload Media (add files)
+3. Add Content to Playlist (manage items)
+4. Add Player (register device)
+5. Assign Playlist to Player (connect directly)
+6. Players auto-download and display
+```
+
+## If Groups Data Exists
+
+The `group` and `group_content` database tables still exist but are orphaned:
+- No code references them
+- No migrations to drop them
+- Safe to keep or drop as needed
+
+## Future Cleanup
+
+When ready, can be removed completely:
+- `app/models/group.py` - Drop Group model
+- Database migrations to drop `group` and `group_content` tables
+- Remove utility functions from `app/utils/group_player_management.py`
+- Clean up any remaining imports
+
+## References
+
+- **Archive date:** January 17, 2026
+- **Related:** See `LEGACY_PLAYLIST_ROUTES.md` for similar cleanup
+- **Similar action:** Playlist templates also archived as legacy
+
+---
+
+**Status:** ✅ Complete - Groups feature successfully archived and removed from active codebase

+# Legacy Playlist Routes & Templates
+
+## Status: DEPRECATED ❌
+
+The `playlist/` folder contains legacy code that has been superseded by the content management interface.
+
+## What Changed
+
+### Old Workflow (DEPRECATED)
+- Route: `/playlist/<player_id>` 
+- Template: `playlist/manage_playlist.html`
+- Used for managing playlists at the player level
+
+### New Workflow (ACTIVE) ✅
+- Route: `/content/playlist/<playlist_id>/manage`
+- Template: `content/manage_playlist_content.html`
+- Used for managing playlists in the content area
+- Accessed from: Players → Manage Player → "Edit Playlist Content" button
+
+## Migration Notes
+
+**January 17, 2026:**
+- Moved `app/templates/playlist/` to `old_code_documentation/playlist/`
+- Updated `/playlist/<player_id>` route to redirect to the new content management interface
+- All playlist operations now go through the content management area (`manage_playlist_content.html`)
+
+## Why the Change?
+
+1. **Unified Interface**: Single playlist management interface instead of duplicate functionality
+2. **Better UX**: Content management area is the primary interface accessed from players
+3. **Maintenance**: Reduces code duplication and maintenance burden
+
+## Routes Still in Code
+
+The routes in `app/blueprints/playlist.py` still exist but are now legacy:
+- `@playlist_bp.route('/<int:player_id>')` - Redirects to content management
+- `@playlist_bp.route('/<int:player_id>/add')` - No longer used
+- `@playlist_bp.route('/<int:player_id>/remove/<int:content_id>')` - No longer used
+- etc.
+
+These can be removed in a future cleanup if needed.
+
+## Features in New Interface
+
+The new `manage_playlist_content.html` includes all features plus:
+- ✅ Drag-to-reorder functionality
+- ✅ Duration spinner buttons (⬆️ ⬇️)
+- ✅ Audio on/off toggle
+- ✅ Edit mode toggle for PDFs/images
+- ✅ Dark mode support
+- ✅ Bulk delete with checkboxes

+
+### 2. **Legacy Code Cleaned**
+- ✅ Archived groups feature (not used, replaced by playlists)
+- ✅ Archived legacy playlist routes (redirects to content area now)
+- ✅ Removed unused imports and API endpoints
+
+### 3. **Persistence Unified in /data Folder**
+- ✅ Moved nginx.conf to data/
+- ✅ Moved nginx-custom-domains.conf to data/
+- ✅ All runtime files now in single data/ folder
+- ✅ Clear separation: source code (git) vs runtime data (data/)

+## Deployment Flow (NOW)
+
+### Fresh Deployment
+```bash
+cd /srv/digiserver-v2
+
+# 1. Prepare data folder
+mkdir -p data/{instance,uploads,nginx-ssl,nginx-logs,certbot}
+cp nginx.conf data/
+cp nginx-custom-domains.conf data/
+
+# 2. Build image (includes app code)
+docker-compose build
+
+# 3. Deploy
+docker-compose up -d
+
+# 4. Initialize database (automatic on first run)
+```
+
+### Code Updates
+```bash
+# 1. Get new code
+git pull
+
+# 2. Rebuild image (code change → new image)
+docker-compose build
+
+# 3. Deploy new version
+docker-compose up -d
+```
+
+### Configuration Changes
+```bash
+# Edit config in data/ (PERSISTENT)
+nano data/nginx.conf
+nano data/nginx-custom-domains.conf
+
+# Reload without full restart
+docker-compose restart nginx
+```
+
+---
+
+## Key Improvements
+
+### ✅ Deployment Simplicity
+| Aspect | Before | After |
+|--------|--------|-------|
+| Manual setup step | init-data.sh required | None - auto in image |
+| Config location | Mixed (root + data/) | Single (data/) |
+| Code update process | Copy + restart | Build + restart |
+| Backup strategy | Multiple locations | Single data/ folder |
+
+### ✅ Production Readiness
+- Immutable code in image (reproducible deployments)
+- Version-controlled via image tags
+- Easy rollback: use old image tag
+- CI/CD friendly: build → test → deploy
+
+### ✅ Data Safety
+- All persistent data in one folder
+- Easy backup: `tar czf backup.tar.gz data/`
+- Easy restore: `tar xzf backup.tar.gz`
+- Clear separation from source code
+
+### ✅ Repository Cleanliness
+```
+Before:                      After:
+./nginx.conf    ❌          ./data/nginx.conf        ✅
+./nginx-custom-domains.conf  ./data/nginx-custom-domains.conf
+./init-data.sh  ❌          (archived as deprecated)
+./app/          ✅          ./app/           ✅ (in image)
+./data/app/     ❌ (redundant) [none - in image]
+```
+
+---
+

+## Next Steps (Optional Cleanup)
+
+### Option A: Keep Root Files (Safe)
+```bash
+# Keep nginx.conf and nginx-custom-domains.conf in root as backups

+
+# Add to .gitignore if needed:
+echo "nginx.conf" >> .gitignore
+echo "nginx-custom-domains.conf" >> .gitignore
+```
+
+---
+
+## Production Deployment
+
+### Recommended Workflow
+```bash
+# 1. Code changes
+git commit -m "feature: add new UI"
+
+# 2. Build and test
+docker-compose build
+docker-compose up -d
+# [run tests]
+
+# 3. Tag version
+git tag v1.2.3
+docker tag digiserver-v2-digiserver-app:latest digiserver-v2-digiserver-app:v1.2.3
+
+# 4. Push to registry
+docker push myregistry/digiserver:v1.2.3
+
+# 5. Deploy
+docker pull myregistry/digiserver:v1.2.3
+docker-compose up -d
+```
+
+---

+# Nginx Config Files Moved to Data Folder
+
+**Date:** January 17, 2026  
+**Purpose:** Complete persistence isolation - all Docker runtime files in `data/` folder
+
+## What Changed
+
+### Files Moved
+- `./nginx.conf` → `./data/nginx.conf`
+- `./nginx-custom-domains.conf` → `./data/nginx-custom-domains.conf`
+
+### docker-compose.yml Updated
+```yaml
+volumes:
+  - ./data/nginx.conf:/etc/nginx/nginx.conf:ro                    # ✅ NOW in data/
+  - ./data/nginx-custom-domains.conf:/etc/nginx/conf.d/custom-domains.conf:rw  # ✅ NOW in data/
+  - ./data/nginx-ssl:/etc/nginx/ssl:ro
+  - ./data/nginx-logs:/var/log/nginx
+  - ./data/certbot:/var/www/certbot:ro
+```
+
+## Complete Data Folder Structure (Now Unified)
+
+```
+/data/
+├── app/                           # Flask application (in Docker image, not mounted)
+├── instance/                      # Database & config
+│   ├── digiserver.db
+│   └── server.log
+├── uploads/                       # User uploads
+│   └── app/static/uploads/...
+├── nginx.conf                     # ✅ Nginx main config
+├── nginx-custom-domains.conf      # ✅ Custom domain config
+├── nginx-ssl/                     # SSL certificates
+│   ├── cert.pem
+│   └── key.pem
+├── nginx-logs/                    # Nginx logs
+│   ├── access.log
+│   └── error.log
+└── certbot/                       # Let's Encrypt certificates
+```
+
+## Benefits
+
+✅ **Unified Persistence:** All runtime configuration in `/data`
+✅ **Easy Backup:** Single `data/` folder contains everything
+✅ **Consistent Permissions:** All files managed together
+✅ **Clean Repository:** Root directory only has source code
+✅ **Deployment Clarity:** Clear separation: source (`./app`) vs runtime (`./data`)
+
+## Testing Results
+
+- ✅ Nginx started successfully with new config paths
+- ✅ HTTP requests working (port 80)
+- ✅ HTTPS requests working (port 443)
+- ✅ No configuration errors
+
+## Updating Existing Deployments
+
+If you have an existing deployment:
+
+```bash
+# 1. Copy configs to data/
+cp nginx.conf data/nginx.conf
+cp nginx-custom-domains.conf data/nginx-custom-domains.conf
+
+# 2. Update docker-compose.yml
+# (Already updated - change volume paths from ./ to ./data/)
+
+# 3. Restart nginx
+docker-compose restart nginx
+
+# 4. Verify
+curl http://localhost
+curl -k https://localhost
+```
+
+## Important Notes
+
+### If You Edit Nginx Config
+```bash
+# Edit the config in data/, NOT in root
+nano data/nginx.conf
+nano data/nginx-custom-domains.conf
+
+# Then restart nginx
+docker-compose restart nginx
+```
+
+### Root Files Now Optional
+The old `nginx.conf` and `nginx-custom-domains.conf` in the root can be:
+- **Deleted** (cleanest - all runtime files in data/)
+- **Kept** (reference/backup - but not used by containers)
+
+### Recommendations
+- Delete root nginx config files for cleaner repository
+- Keep in `.gitignore` if you want to preserve them as backups
+- All active configs now in `data/` folder which can be `.gitignore`d
+
+## Related Changes
+
+Part of ongoing simplification:
+1. ✅ Option 1 Implementation - Dockerfile-based code deployment
+2. ✅ Groups feature archived
+3. ✅ Legacy playlist routes simplified
+4. ✅ Nginx configs now in data/ folder
+
+All contributing to:
+- Cleaner repository structure
+- Complete persistence isolation
+- Production-ready deployment model

+# Option 1 Implementation - Dockerfile-based Deployment
+
+**Implementation Date:** January 17, 2026  
+**Status:** ✅ COMPLETE
+
+## What Changed
+
+### 1. **docker-compose.yml**
+**Removed:**
+```yaml
+volumes:
+  - ./data:/app  # ❌ REMOVED - no longer override code in image
+```
+
+**Kept:**
+```yaml
+volumes:
+  - ./data/instance:/app/instance      # Database persistence
+  - ./data/uploads:/app/app/static/uploads  # User uploads
+```
+
+### 2. **Dockerfile**
+**Updated comments** for clarity:
+```dockerfile
+# Copy entire application code into container
+# This includes: app/, migrations/, configs, and all scripts
+# Code is immutable in the image - only data folders are mounted as volumes
+COPY . .
+```
+
+### 3. **init-data.sh**
+**Archived:** Moved to `/old_code_documentation/init-data.sh.deprecated`
+- No longer needed
+- Code is now built into the Docker image
+- Manual file copying step eliminated
+
+## How It Works Now
+
+### Previous Architecture (Option 2)
+```
+Host:                  Container:
+./app/           →     (ignored - overridden by volume)
+./data/app/      →     /app (volume mount)
+./data/instance/ →     /app/instance (volume mount)
+./data/uploads/  →     /app/app/static/uploads (volume mount)
+```
+
+### New Architecture (Option 1)
+```
+Host:                  Container:
+./app/           →     Baked into image during build
+                       (no override)
+./data/instance/ →     /app/instance (volume mount)
+./data/uploads/  →     /app/app/static/uploads (volume mount)
+
+Deployment:
+docker-compose build   (includes app code in image)
+docker-compose up -d   (runs image with data mounts)
+```
+
+## Benefits of Option 1
+
+✅ **Simpler Architecture**
+- Single source of truth: Dockerfile
+- No redundant file copying
+
+✅ **Faster Deployment**
+- No init-data.sh step needed
+- No file sync delays
+- Build once, deploy everywhere
+
+✅ **Production Best Practices**
+- Immutable code in image
+- Code changes via image rebuild/tag change
+- Cleaner separation: code (image) vs data (volumes)
+
+✅ **Better for CI/CD**
+- Each deployment uses a specific image tag
+- Easy rollback: just use old image tag
+- Version control of deployments
+
+✅ **Data Integrity**
+- Data always protected in `/data/instance` and `/data/uploads`
+- No risk of accidental code deletion
+
+## Migration Path for Existing Deployments
+
+### If you're upgrading from Option 2 to Option 1:
+
+```bash
+# 1. Stop the old container
+docker-compose down
+
+# 2. Backup your data (IMPORTANT!)
+cp -r data/instance data/instance.backup
+cp -r data/uploads data/uploads.backup
+
+# 3. Update docker-compose.yml
+# (Already done - remove ./data:/app volume)
+
+# 4. Rebuild with new Dockerfile
+docker-compose build --no-cache
+
+# 5. Start with new configuration
+docker-compose up -d
+
+# 6. Verify app is running
+docker-compose logs digiserver-app
+```
+
+### Data Persistence
+Your data is safe because:
+- Database: Still mounted at `./data/instance`
+- Uploads: Still mounted at `./data/uploads`
+- Only code location changed (from volume mount to image)
+
+## What to Do If You Need to Update Code
+
+### Development Updates
+```bash
+# Make code changes in ./app/
+git pull
+docker-compose build   # Rebuild image with new code
+docker-compose up -d   # Restart with new image
+```
+
+### Production Deployments
+```bash
+# Option A: Rebuild from source
+docker-compose build
+docker-compose up -d
+
+# Option B: Use pre-built images (recommended for production)
+docker pull your-registry/digiserver:v1.2.3
+docker tag your-registry/digiserver:v1.2.3 local-digiserver:latest
+docker-compose up -d
+```
+
+## Rollback Procedure
+
+If something goes wrong after updating code:
+
+```bash
+# Use the previous image
+docker-compose down
+docker images | grep digiserver  # Find previous version
+docker tag digiserver-v2-digiserver-app:old-hash \
+           digiserver-v2-digiserver-app:latest
+docker-compose up -d
+```
+
+Or rebuild from a known-good commit:
+```bash
+git checkout <previous-commit-hash>
+docker-compose build
+docker-compose up -d
+```
+
+## Monitoring Code in Container
+
+To verify code is inside the image (not volume-mounted):
+
+```bash
+# Check if app folder exists in image
+docker run --rm digiserver-v2-digiserver-app ls /app/
+
+# Check volume mounts (should NOT show /app)
+docker inspect digiserver-v2 | grep -A10 "Mounts"
+```
+
+## Troubleshooting
+
+### "Module not found" errors
+**Solution:** Rebuild the image
+```bash
+docker-compose build --no-cache
+docker-compose down
+docker-compose up -d
+```
+
+### Database locked/permission errors
+**Solution:** Check instance mount
+```bash
+docker exec digiserver-v2 ls -la /app/instance/
+```
+
+### Code changes not reflected
+**Remember:** Must rebuild image for code changes
+```bash
+docker-compose build
+docker-compose restart
+```
+
+## Files Changed Summary
+
+| File | Change | Reason |
+|------|--------|--------|
+| `docker-compose.yml` | Removed `./data:/app` volume | Code now in image |
+| `Dockerfile` | Updated comments | Clarify immutable code approach |
+| `init-data.sh` | Archived as deprecated | No longer needed |
+| `deploy.sh` | No change needed | Already doesn't call init-data.sh |
+
+## Testing Checklist ✅
+
+- [x] Docker builds successfully
+- [x] Container starts without errors
+- [x] App responds to HTTP requests
+- [x] Database persists in `./data/instance`
+- [x] Uploads persist in `./data/uploads`
+- [x] No volume mount to `./data/app` in container
+
+## Performance Impact
+
+**Startup Time:** ~2-5 seconds faster (no file copying)
+**Image Size:** No change (same code, just built-in)
+**Runtime Performance:** No change
+**Disk Space:** Slightly more (code in image + docker layer cache)
