 # Changelog
 
-## Unreleased
+## Upcoming - 1.3.2
 
-### 1.3
+### New Features
 
-- Add individual pagination control system per entity type
-  - `BK_SETS_SERVER_SIDE_PAGINATION`: Enable/disable pagination for sets
-  - `BK_PARTS_SERVER_SIDE_PAGINATION`: Enable/disable pagination for parts
-  - `BK_MINIFIGURES_SERVER_SIDE_PAGINATION`: Enable/disable pagination for minifigures
-  - Device-specific pagination sizes (desktop/mobile) for each entity type
-  - Supports search, filtering, and sorting in both server-side and client-side modes
-  - Consolidated duplicate code across parts.js, problems.js, and minifigures.js
-  - Created shared functions in collapsible-state.js for common operations
+- **Database Integrity Check and Cleanup**
+  - Added database integrity scanner to detect orphaned records and foreign key violations
+  - New "Check Database Integrity" button in admin panel scans for issues
+  - Detects orphaned sets, parts, and parts with missing set references
+  - Two-step cleanup process with Bootstrap modal confirmation
+  - Warning prompts users to backup database before cleanup
+  - Automatic cleanup removes all orphaned records in one operation
+  - Detailed scan results show affected records with counts and descriptions
+- **Database Optimization**
+  - Added "Optimize Database" button to re-create performance indexes
+  - Safe to run after database imports or restores
+  - Re-creates all indexes from migration #19 using `CREATE INDEX IF NOT EXISTS`
+  - Runs `ANALYZE` to rebuild query statistics
+  - Runs `PRAGMA optimize` for additional query plan optimization
+  - Helpful after importing backup databases that may lack performance optimizations
+
+## 1.3.1
+
+### Bug Fixes
+
+- **Fixed foreign key constraint errors during set imports**: Resolved `FOREIGN KEY constraint failed` errors when importing sets with parts and minifigures
+  - Fixed insertion order in `bricktracker/part.py`: Parent records (`rebrickable_parts`) now inserted before child records (`bricktracker_parts`)
+  - Fixed insertion order in `bricktracker/minifigure.py`: Parent records (`rebrickable_minifigures`) now inserted before child records (`bricktracker_minifigures`)
+  - Ensures foreign key references are valid when SQLite checks constraints
+- **Fixed set metadata updates**: Owner, status, and tag checkboxes now properly persist changes on set details page
+  - Fixed `update_set_state()` method to commit database transactions (was using deferred execution without commit)
+  - All metadata updates (owner, status, tags, storage, purchase info) now work consistently
+- **Fixed nil image downloads**: Placeholder images for parts and minifigures without images now download correctly
+  - Removed early returns that prevented nil image downloads
+  - Nil images now properly saved to configured folders (e.g., `/app/data/parts/nil.jpg`)
+- **Fixed error logging for missing files**: File not found errors now show actual configured folder paths instead of just URL paths
+  - Added detailed logging showing both file path and configured folder for easier debugging
+- **Fixed minifigure filters in client-side pagination mode**: Owner and other filters now work correctly when server-side pagination is disabled
+  - Aligned filter behavior with parts page (applies filters server-side, then loads filtered data for client-side search)
+
+## 1.3
+
+### Breaking Changes 
+
+#### Data Folder Consolidation
+
+> **Warning** 
+> **BREAKING CHANGE**: Version 1.3 consolidates all user data into a single `data/` folder for easier backup and volume mapping.
+
+- **Path handling**: All relative paths are now resolved relative to the application root (`/app` in Docker)
+  - Example: `data/app.db` → `/app/data/app.db`
+
+- **New default paths** (automatically used for new installations):
+  - Database: `data/app.db` (was: `app.db` in root)
+  - Configuration: `data/.env` (was: `.env` in root) - *optional, backward compatible*
+  - CSV files: `data/*.csv` (was: `*.csv` in root)
+  - Images/PDFs: `data/{sets,parts,minifigures,instructions}/` (was: `static/*`)
+
+- **Configuration file (.env) location**:
+  - New recommended location: `data/.env` (included in data volume, settings persist)
+  - Backward compatible: `.env` in root still works (requires volume mount for admin panel persistence)
+  - Priority: `data/.env` > `.env` (automatic detection, no migration required)
+
+- **Migration options**:
+  1. **Migrate to new structure** (recommended - single volume for all data including .env)
+  2. **Keep current setup** (backward compatible - old paths continue to work)
+
+See [Migration Guide](docs/migration_guide.md) for detailed instructions
+
+#### Default Minifigures Folder Change
+
+> **Warning**
+> **BREAKING CHANGE**: Default minifigures folder path changed from `minifigs` to `minifigures`
+
+- **Impact**: Users who relied on the default `BK_MINIFIGURES_FOLDER` value (without explicitly setting it) will need to either:
+  1. Set `BK_MINIFIGURES_FOLDER=minifigs` in their environment to maintain existing behavior, or
+  2. Rename their existing `minifigs` folder to `minifigures`
+- **No impact**: Users who already have `BK_MINIFIGURES_FOLDER` explicitly configured
+- Improved consistency across documentation and Docker configurations
+
+### New Features
+
+- **Live Settings changes**
+  - Added live environment variable configuration management system
+    - Configuration Management interface in admin panel with live preview and badge system
+    - **Live settings**: Can be changed without application restart (menu visibility, table display, pagination, features)
+    - **Static settings**: Require restart but can be edited and saved to .env file (authentication, server, database, API keys)
+    - Advanced badge system showing value status: True/False for booleans, Set/Default/Unset for other values, Changed indicator
+    - Live API endpoints: `/admin/api/config/update` for immediate changes, `/admin/api/config/update-static` for .env updates
+    - Form pre-population with current values and automatic page reload after successful live updates
+  - Fixed environment variable lock detection in admin configuration panel
+    - Resolved bug where all variables appeared "locked" after saving live settings
+    - Lock detection now correctly identifies only Docker environment variables set before .env loading
+    - Variables set via Docker's `environment:` directive remain properly locked
+    - Variables from data/.env or root .env are correctly shown as editable
+  - Added configuration persistence warning in admin panel
+    - Warning banner shows when using .env in root (non-persistent)
+    - Success banner shows when using data/.env (persistent)
+    - Provides migration instructions directly in the UI
+- **Spare Parts**
+  - Added spare parts control options
+    - `BK_SKIP_SPARE_PARTS`: Skip importing spare parts when downloading sets from Rebrickable (parts not saved to database)
+    - `BK_HIDE_SPARE_PARTS`: Hide spare parts from all parts lists (parts must still be in database)
+    - Both options are live-changeable in admin configuration panel
+    - Options can be used independently or together for flexible spare parts management
+    - Affects all parts displays: /parts page, set details accordion, minifigure parts, and problem parts
+- **Pagination**
+  - Added individual pagination control system per entity type
+    - `BK_SETS_SERVER_SIDE_PAGINATION`: Enable/disable pagination for sets
+    - `BK_PARTS_SERVER_SIDE_PAGINATION`: Enable/disable pagination for parts
+    - `BK_MINIFIGURES_SERVER_SIDE_PAGINATION`: Enable/disable pagination for minifigures
+    - Device-specific pagination sizes (desktop/mobile) for each entity type
+    - Supports search, filtering, and sorting in both server-side and client-side modes
+- **Peeron Instructions**
+  - Added Peeron instructions integration
+    - Full image caching system with automatic thumbnail generation
+    - Optimized HTTP calls by downloading full images once and generating thumbnails locally
+    - Automatic cache cleanup after PDF generation to save disk space
+- **Parts checkmark**
+  - Added parts checking/inventory system
+    - New "Checked" column in parts tables for tracking inventory progress
+    - Checkboxes to mark parts as verified during set walkthrough
+    - `BK_HIDE_TABLE_CHECKED_PARTS`: Environment variable to hide checked column
+- **Set Consolidation**
+  - Added set consolidation/grouping functionality
+    - Automatic grouping of duplicate sets on main sets page
+    - Shows instance count with stack icon badge (e.g., "3 copies")
+    - Expandable drawer interface to view all set copies individually
+    - Full set cards for each instance with all badges, statuses, and functionality
+    - `BK_SETS_CONSOLIDATION`: Environment variable to enable/disable consolidation (default: false)
+    - Backwards compatible - when disabled, behaves exactly like original individual view
+    - Improved theme filtering: handles duplicate theme names correctly
+    - Fixed set number sorting: proper numeric sorting in both ascending and descending order
+    - Mixed status indicators for consolidated sets: three-state checkboxes (unchecked/partial/checked) with count badges
+      - Template logic handles three states: none (0/2), all (2/2), partial (1/2) with visual indicators
+      - Purple overlay styling for partial states, disabled checkboxes for read-only consolidated status display
+      - Individual sets maintain full interactive checkbox functionality
+- **Statistics**
+  - Added comprehensive statistics system (#91)
+    - New Statistics page with collection analytics
+    - Financial overview: total cost, average price, price range, investment tracking
+    - Collection metrics: total sets, unique sets, parts count, minifigures count
+    - Theme distribution statistics with clickable drill-down to filtered sets
+    - Storage location statistics showing sets per location with value calculations
+    - Purchase location analytics with spending patterns and date ranges

+      - Purchases by Year: Tracks spending patterns and acquisition timeline
+      - Year summary with peak collection/spending years and timeline insights
+    - Enhanced statistics interface and functionality
+      - Collapsible sections: All statistics sections have clickable headers to expand/collapse
+      - Collection growth charts: Line charts showing sets, parts, and minifigures over time
+      - Configuration options: `BK_STATISTICS_SHOW_CHARTS` and `BK_STATISTICS_DEFAULT_EXPANDED` environment variables
+- **Admin Page Section Expansion**
+  - Added configurable admin page section expansion
+    - `BK_ADMIN_DEFAULT_EXPANDED_SECTIONS`: Environment variable to specify which sections expand by default
+    - Accepts comma-separated list of section names (e.g., "database,theme,instructions")
+    - Valid sections: authentication, instructions, image, theme, retired, metadata, owner, purchase_location, status, storage, tag, database
+    - URL parameters take priority over configuration (e.g., `?open_database=1`)
+    - Database section expanded by default to maintain original behavior
+    - Smart metadata handling: sub-section expansion automatically expands parent metadata section
+- **Duplicate Sets filter**
+  - Added duplicate sets filter functionality
+    - New filter button on Sets page to show only duplicate/consolidated sets
+    - `BK_SHOW_SETS_DUPLICATE_FILTER`: Environment variable to show/hide the filter button (default: true)
+    - Works with both server-side and client-side pagination modes
+    - Consolidated mode: Shows sets that have multiple instances
+    - Non-consolidated mode: Shows sets that appear multiple times in collection
+- **Bricklink Links**
+  - Added BrickLink links for sets
+    - BrickLink badge links now appear on set cards and set details pages alongside Rebrickable links
+    - `BK_BRICKLINK_LINK_SET_PATTERN`: New environment variable for BrickLink set URL pattern (default: https://www.bricklink.com/v2/catalog/catalogitem.page?S={set_num})
+    - Controlled by existing `BK_BRICKLINK_LINKS` environment variable
+- **Dark Mode** 
+  - Added dark mode support
+    - `BK_DARK_MODE`: Environment variable to enable dark mode theme (default: false)
+    - Uses Bootstrap 5.3's native dark mode with `data-bs-theme` attribute
+    - Live-changeable via Admin > Live Settings
+    - Setting persists across sessions via .env file
+- **Alphanumetic Set Number**
+  - Added alphanumeric set number support
+    - Database schema change: Set number column changed from INTEGER to TEXT
+    - Supports LEGO promotional and special edition sets with letters in their numbers
+    - Examples: "McDR6US-1", "COMCON035-1", "EG00021-1"
+    
+### Improvements 
+
+- Improved WebSocket/Socket.IO reliability for mobile devices
+  - Changed connection strategy to polling-first with automatic WebSocket upgrade
+  - Increased connection timeout to 30 seconds for slow mobile networks
+  - Added ping/pong keepalive settings (30s timeout, 25s interval)
+  - Improved server-side connection logging with user agent and transport details
 - Fixed dynamic sort icons across all pages
   - Sort icons now properly toggle between ascending/descending states
 - Improved DataTable integration
@@ -23,30 +205,45 @@
   - Preserves selection state during dropdown consolidation
   - Consistent search behavior (instant for client-side, Enter key for server-side)
   - Mobile-friendly pagination navigation
-- Add Peeron instructions integration
-  - Full image caching system with automatic thumbnail generation
-  - Optimized HTTP calls by downloading full images once and generating thumbnails locally
-  - Automatic cache cleanup after PDF generation to save disk space
-- Add parts checking/inventory system
-  - New "Checked" column in parts tables for tracking inventory progress
-  - Checkboxes to mark parts as verified during set walkthrough
-  - `BK_HIDE_TABLE_CHECKED_PARTS`: Environment variable to hide checked column
-- Add set consolidation/grouping functionality
-  - Automatic grouping of duplicate sets on main sets page
-  - Shows instance count with stack icon badge (e.g., "3 copies")
-  - Expandable drawer interface to view all set copies individually
-  - Full set cards for each instance with all badges, statuses, and functionality
-  - `BK_SETS_CONSOLIDATION`: Environment variable to enable/disable consolidation (default: false)
-  - Backwards compatible - when disabled, behaves exactly like original individual view
-  - Improved theme filtering: handles duplicate theme names correctly
-  - Fixed set number sorting: proper numeric sorting in both ascending and descending order
-  - Mixed status indicators for consolidated sets: three-state checkboxes (unchecked/partial/checked) with count badges
-    - Enhanced SQL aggregation with `IFNULL(SUM())` for accurate count statistics
-    - Template logic handles three states: none (0/2), all (2/2), partial (1/2) with visual indicators
-    - Purple overlay styling for partial states, disabled checkboxes for read-only consolidated status display
-    - Individual sets maintain full interactive checkbox functionality
-  
-### 1.2.4
+- Added performance optimization
+  - SQLite WAL Mode:
+    - Increased cache size to 10,000 pages (~40MB) for faster query execution
+    - Set temp_store to memory for accelerated temporary operations
+    - Enabled foreign key constraints and optimized synchronous mode
+    - Added ANALYZE for improved query planning and statistics
+  - Database Indexes (Migration 0019):
+    - High-impact composite index for problem parts aggregation (`idx_bricktracker_parts_id_missing_damaged`)
+    - Parts lookup optimization (`idx_bricktracker_parts_part_color_spare`)
+    - Set storage filtering (`idx_bricktracker_sets_set_storage`)
+    - Search optimization with case-insensitive indexes (`idx_rebrickable_sets_name_lower`, `idx_rebrickable_parts_name_lower`)
+    - Year and theme filtering optimization (`idx_rebrickable_sets_year`, `idx_rebrickable_sets_theme_id`)
+    - Additional indexes for purchase dates, quantities, sorting, and minifigures aggregation
+  - Statistics Query Optimization:
+    - Replaced separate subqueries with efficient CTEs (Common Table Expressions)
+    - Consolidated aggregations for set, part, minifigure, and financial statistics
+  - Added default image handling for sets without images
+    - Sets with null/missing images from Rebrickable API now display placeholder image
+    - Automatic fallback to nil.png from parts folder for set previews
+    - Copy of nil placeholder saved as set image for consistent display across all routes
+    - Prevents errors when downloading sets that have no set_img_url in API response
+  - Fixed instructions download from Rebrickable
+    - Replaced cloudscraper with standard requests library
+    - Resolves 403 Forbidden errors when downloading instruction PDFs
+  - Fixed instructions display and URL generation

+    - Fixed Peeron PDF creation to use correct data folder path
+  - Fixed foreign key constraint error when adding sets
+    - Rebrickable set is now inserted before BrickTracker set to satisfy FK constraints
+    - Resolves "FOREIGN KEY constraint failed" error when adding sets
+  - Fixed atomic transaction handling for set downloads
+    - All database operations during set addition now use deferred execution
+    - Ensures all-or-nothing behavior: if any part fails (set info, parts, minifigs), nothing is committed
+    - Prevents partial set additions that would leave the database in an inconsistent state
+    - Metadata updates (owners, tags) now defer until final commit

+# Data Folder Migration Guide (Docker Compose)
+
+## Overview
+
+Starting with version 1.3, BrickTracker consolidates all user data into a single `data/` folder for easier backup, persistence, and volume mapping.
+
+**This guide assumes you are running BrickTracker using Docker Compose with bind mounts.**
+
+> **Note:** If you're using Docker named volumes instead of bind mounts, you'll need to manually copy data between volumes. The commands below are specific to bind mount setups.
+
+**Backup your data before to making any changes!**
+
+## What Changed?
+
+### New Default Structure (v1.3+)
+
+**All relative paths are resolved relative to `/app` inside the container.** Previously all paths were relative to `/app/static`. 
+
+For example: `data/app.db` → `/app/data/app.db`
+
+```
+Container (/app/):
+├── data/                   # NEW: Single volume mount for all user data
+│   ├── .env                # Configuration (recommended location)
+│   ├── app.db              # Database
+│   ├── retired_sets.csv    # Downloaded CSV files
+│   ├── themes.csv
+│   ├── sets/               # Set images
+│   ├── parts/              # Part images
+│   ├── minifigures/        # Minifigure images
+│   └── instructions/       # PDF instructions
+└── static/                 # App assets
+    ├── brick.png
+    ├── styles.css
+    └── scripts/
+```
+
+**Docker Compose volume:** Single mount `./data:/app/data/`
+
+### Previous Structure (v1.2 and earlier)
+
+```
+Container (/app/):
+├── app.db                   # Mounted from ./data/ on host
+├── retired_sets.csv         # Mounted from ./data/ on host
+├── themes.csv
+└── static/
+    ├── instructions/       # Separate bind mount
+    ├── minifigs/           # Separate bind mount
+    ├── parts/              # Separate bind mount
+    ├── sets/               # Separate bind mount
+```
+
+**Docker Compose bind mounts:** 5 separate mounts
+```yaml
+volumes:
+  - ./data:/app/
+  - ./instructions:/app/static/instructions/
+  - ./minifigs:/app/static/minifigs/
+  - ./parts:/app/static/parts/
+  - ./sets:/app/static/sets/
+```
+
+## Migration Options
+
+> **Warning**
+> Backup your data before making any changes! 
+
+### Option 1: Migrate to New Data Folder Structure (Recommended)
+
+This is the recommended approach for cleaner backups and simpler bind mount management.
+
+1. **Stop the container:**
+   ```bash
+   docker compose down
+   ```
+
+2. **Create new consolidated data directory on host:**
+   ```bash
+   mkdir -p ./bricktracker-data/{sets,parts,minifigures,instructions}
+   ```
+
+3. **Move data from old bind mount locations to new structure:**
+
+   Assuming your old `compose.yaml` had:
+   - `./data:/app/` (contains app.db, retired_sets.csv, themes.csv)
+   - `./instructions:/app/static/instructions/`
+   - `./minifigs:/app/static/minifigs/`
+   - `./parts:/app/static/parts/`
+   - `./sets:/app/static/sets/`
+
+   > Default location for minifigures changed from `minifigs` to `minifigures` 
+
+   Run:
+   ```bash
+   # Move configuration file (optional but recommended)
+   mv .env ./bricktracker-data/.env
+
+   # Move database and CSV files
+   mv ./data/app.db ./bricktracker-data/
+   mv ./data/retired_sets.csv ./bricktracker-data/
+   mv ./data/themes.csv ./bricktracker-data/
+
+   # Move image and instruction folders
+   mv ./instructions/* ./bricktracker-data/instructions/
+   mv ./minifigs/* ./bricktracker-data/minifigures/
+   mv ./parts/* ./bricktracker-data/parts/
+   mv ./sets/* ./bricktracker-data/sets/
+   ```
+
+4. **Update `compose.yaml` to use single bind mount:**
+   ```yaml
+   services:
+     bricktracker:
+       volumes:
+         - ./bricktracker-data:/app/data/
+
+   # Remove old volume mounts and env_file (if .env was moved to data/)
+   ```
+
+5. **Remove old path overrides from `.env` (if present):**
+   Delete any lines starting with:
+   - `BK_DATABASE_PATH=`
+   - `BK_INSTRUCTIONS_FOLDER=`
+   - `BK_MINIFIGURES_FOLDER=`
+   - `BK_PARTS_FOLDER=`
+   - `BK_SETS_FOLDER=`
+   - `BK_RETIRED_SETS_PATH=`
+   - `BK_THEMES_PATH=`
+
+6. **Start the container:**
+   ```bash
+   docker compose up -d
+   ```
+
+7. **Verify everything works:**
+   ```bash
+   docker compose logs -f bricktracker
+   # Check the web interface to ensure images/data are loading
+   ```
+
+8. **Clean up old directories (after verification):**
+   ```bash
+   rm -r ./data ./instructions ./minifigs ./parts ./sets
+   ```
+
+### Option 2: Keep Current Setup (No Data Migration)
+
+If you want to keep your current volume structure without moving any files:
+
+1. **Add these environment variables to your `.env` file:**
+
+   ```env
+   # Keep database and CSV files in /data volume (old location)
+   BK_DATABASE_PATH=app.db
+   BK_RETIRED_SETS_PATH=retired_sets.csv
+   BK_THEMES_PATH=themes.csv
+
+   # Keep image/instruction folders in static/ (old location)
+   BK_INSTRUCTIONS_FOLDER=static/instructions
+   BK_MINIFIGURES_FOLDER=static/minifigures
+   BK_PARTS_FOLDER=static/parts
+   BK_SETS_FOLDER=static/sets
+   ```
+
+2. **Keep your existing volume mounts in `compose.yaml`:**
+
+   ```yaml
+   volumes:
+     - ./data:/app/
+     - ./instructions:/app/static/instructions/
+     - ./minifigures:/app/static/minifigures/
+     - ./parts:/app/static/parts/
+     - ./sets:/app/static/sets/
+   ```
+
+3. **Update to v1.3 and restart:**
+   ```bash
+   docker compose pull
+   docker compose up -d
+   ```
+
+That's it! Your existing setup will continue to work.
+
+## Configuration File (.env) Location
+
+### New Behavior (v1.3+)
+
+BrickTracker now supports `.env` in two locations with automatic detection:
+
+1. **data/.env** (recommended - new location)
+   - Included in data volume backup
+   - Settings persist when changed via admin panel
+   - Priority location (checked first)
+   - **No `env_file` needed** - app reads it directly from `/app/data/.env`
+
+2. **.env** (backward compatibility - root)
+   - Continues to work for existing installations
+   - Requires `env_file: .env` in compose.yaml for Docker to load it at startup
+   - Not included in data volume (unless you add `.env` to `data/`)
+
+### Migration Steps for .env
+
+**Option A: Move to data folder (recommended)**
+
+```bash
+# Move .env to data folder
+mv .env data/.env
+
+# Update compose.yaml - remove or comment out env_file
+# The app will automatically find and use /app/data/.env
+```
+
+**Option B: Keep in root (backward compatible)**
+
+```bash
+# No changes needed
+# Keep env_file: .env in compose.yaml
+# App will use .env from root as fallback
+```
+
+**Note:** The application automatically detects which location has the .env file at runtime. No Docker Compose `env_file` directive is needed for `data/.env` because the app reads it directly from the mounted volume.
+
+## Configuration Reference
+
+### New Default Paths (v1.3+)
+
+All paths are relative to `/app` inside the container.
+
+| Config Variable | Default Value | Resolves To (Container) | Description |
+|----------------|---------------|------------------------|-------------|
+| `BK_DATABASE_PATH` | `data/app.db` | `/app/data/app.db` | Database file |
+| `BK_RETIRED_SETS_PATH` | `data/retired_sets.csv` | `/app/data/retired_sets.csv` | Retired sets CSV |
+| `BK_THEMES_PATH` | `data/themes.csv` | `/app/data/themes.csv` | Themes CSV |
+| `BK_INSTRUCTIONS_FOLDER` | `data/instructions` | `/app/data/instructions` | PDF instructions |
+| `BK_MINIFIGURES_FOLDER` | `data/minifigures` | `/app/data/minifigures` | Minifigure images |
+| `BK_PARTS_FOLDER` | `data/parts` | `/app/data/parts` | Part images |
+| `BK_SETS_FOLDER` | `data/sets` | `/app/data/sets` | Set images |
+
+**Docker Compose bind mount:** `./bricktracker-data:/app/data/` (single mount)
+
+### Old Paths (v1.2 and earlier)
+
+To preserve old volume structure without migration, add to `.env`:
+
+| Config Variable | Value to Preserve Old Behavior | Resolves To (Container) |
+|----------------|-------------------------------|------------------------|
+| `BK_DATABASE_PATH` | `app.db` | `/app/app.db` |
+| `BK_RETIRED_SETS_PATH` | `retired_sets.csv` | `/app/retired_sets.csv` |
+| `BK_THEMES_PATH` | `themes.csv` | `/app/themes.csv` |
+| `BK_INSTRUCTIONS_FOLDER` | `static/instructions` | `/app/static/instructions` |
+| `BK_MINIFIGURES_FOLDER` | `static/minifigs` | `/app/static/minifigs` |
+| `BK_PARTS_FOLDER` | `static/parts` | `/app/static/parts` |
+| `BK_SETS_FOLDER` | `static/sets` | `/app/static/sets` |
+
+## Benefits of New Structure
+
+1. **Single Bind Mount**: One `./bricktracker-data:/app/data/` mount instead of five separate mounts
+2. **Easier Backups**: All user data in one location - just backup the `bricktracker-data` directory
+3. **Cleaner Separation**: User data separated from application assets
+4. **Better Portability**: Migrate between systems by copying/moving single directory
+
+## Troubleshooting
+
+### Images/Instructions Not Loading After Migration
+
+1. **Check if data was copied correctly:**
+   ```bash
+   docker compose exec bricktracker ls -la /app/data/
+   docker compose exec bricktracker ls -la /app/data/sets/
+   docker compose exec bricktracker ls -la /app/data/instructions/
+   ```
+
+2. **Verify bind mount:**
+   ```bash
+   docker compose config
+   # Should show: volumes: - ./bricktracker-data:/app/data/
+   ```
+
+3. **Check logs for path errors:**
+   ```bash
+   docker compose logs -f
+   ```
+
+4. **Verify no old environment overrides:**
+   ```bash
+   cat .env | grep BK_
+   ```
+
+### Database Not Found
+
+1. **Check database file location in container:**
+   ```bash
+   docker compose exec bricktracker ls -la /app/data/app.db
+   ```
+
+2. **If using old setup, verify environment variables:**
+   ```bash
+   docker compose exec bricktracker env | grep BK_DATABASE_PATH
+   ```
+
+3. **Check host directory contains database:**
+   ```bash
+   ls -la ./bricktracker-data/
+   # Should show: app.db, retired_sets.csv, themes.csv, and subdirectories
+   ```
+
+### Settings Don't Persist After Restart
+
+**Error:** Admin panel changes revert after `docker compose restart`
+
+**Solution:**
+
+This happens when `.env` is not in a volume. Choose one:
+
+**Option A: Move .env to data folder**
+```bash
+mv .env data/.env
+# Update compose.yaml - remove or comment out env_file
+# The app will automatically find and use /app/data/.env
+```
+
+**Option B: Mount .env as volume**
+```yaml
+volumes:
+  - ./.env:/app/.env
+```
+
+### Permission Errors
+
+If you see permission errors after migration:
+
+```bash
+# Fix permissions on bind-mounted directory
+sudo chown -R $(id -u):$(id -g) ./bricktracker-data
+```
+
+**Permission denied writing .env:**
+
+If the admin panel shows an error when saving settings:
+
+1. Ensure .env file is writable by container user
+2. If using volume mount, check host file permissions
+3. In container: `docker exec BrickTracker ls -la /app/.env` or `/app/data/.env`
+
+### Reverting Migration
+
+If you need to revert to the old structure:
+
+1. Stop the container: `docker compose down`
+2. Restore old `compose.yaml` with 5 volume mounts
+3. Add old path environment variables to `.env` (see Option 1)
+4. Start: `docker compose up -d`
