+- Escape quotes in JSON with `\"`
+- Use `\\n` for newlines in the body
+- Remove apostrophes or escape them carefully to avoid shell parsing issues
+- Replace `ISSUE_NUMBER` with the actual issue number
+
+## Database Migrations
+
+When you add new database fields:
+
+1. **Update the Model** (in `models.py`)
+2. **Create a Migration Script** (e.g., `migrate_password_reset.py`)
+3. **Run the Migration** before deploying:
+   ```bash
+   python3 migrate_password_reset.py
+   ```
+4. **Test Locally** to ensure the migration works
+5. **Deploy** to production and run the migration there too
+
+## Docker Deployment
+
+### Build and Push
+```bash
+# Build the image
+docker build -t git.scorpi.us/chelsea/balanceboard:latest .
+
+# Push to registry
+docker push git.scorpi.us/chelsea/balanceboard:latest
+```
+
+### Deploy on Server
+```bash
+# SSH to server
+ssh user@reddit.scorpi.us
+
+# Pull latest image
+cd /path/to/balanceboard
+docker-compose pull
+
+# Restart services
+docker-compose down
+docker-compose up -d
+
+# Check logs
+docker-compose logs -f balanceboard

+# Filter Pipeline Documentation
+
+## Overview
+
+BalanceBoard's Filter Pipeline is a plugin-based content filtering system that provides intelligent categorization, moderation, and ranking of posts using AI-powered analysis with aggressive caching for cost efficiency.
+
+## Architecture
+
+### Three-Level Caching System
+
+1. **Level 1: Memory Cache** (5-minute TTL)
+   - In-memory cache for fast repeated access
+   - Cleared on application restart
+
+2. **Level 2: AI Analysis Cache** (Permanent, content-hash based)
+   - Stores AI results (categorization, moderation, quality scores)
+   - Keyed by SHA-256 hash of content
+   - Never expires - same content always returns cached results
+   - **Huge cost savings**: Never re-analyze the same content
+
+3. **Level 3: Filterset Results Cache** (24-hour TTL)
+   - Stores final filter results per filterset
+   - Invalidated when filterset definition changes
+   - Enables instant filterset switching
+
+### Pipeline Stages
+
+Posts flow through 4 sequential stages:
+
+```
+Raw Post
+  ↓
+1. Categorizer  (AI: topic detection, tags)
+  ↓
+2. Moderator    (AI: safety, quality, sentiment)
+  ↓
+3. Filter       (Rules: apply filterset conditions)
+  ↓
+4. Ranker       (Score: quality + recency + source + engagement)
+  ↓
+Filtered & Scored Post
+```
+
+#### Stage 1: Categorizer
+- **Purpose**: Detect topics and assign categories
+- **AI Model**: Llama 70B (cheap model)
+- **Caching**: Permanent (by content hash)
+- **Output**: Categories, category scores, tags
+
+#### Stage 2: Moderator
+- **Purpose**: Safety and quality analysis
+- **AI Model**: Llama 70B (cheap model)
+- **Caching**: Permanent (by content hash)
+- **Metrics**:
+  - Violence score (0.0-1.0)
+  - Sexual content score (0.0-1.0)
+  - Hate speech score (0.0-1.0)
+  - Harassment score (0.0-1.0)
+  - Quality score (0.0-1.0)
+  - Sentiment (positive/neutral/negative)
+
+#### Stage 3: Filter
+- **Purpose**: Apply filterset rules
+- **AI**: None (fast rule evaluation)
+- **Rules Supported**:
+  - `equals`, `not_equals`
+  - `in`, `not_in`
+  - `min`, `max`
+  - `includes_any`, `excludes`
+
+#### Stage 4: Ranker
+- **Purpose**: Calculate relevance scores
+- **Scoring Factors**:
+  - Quality (30%): From Moderator stage
+  - Recency (25%): Age-based decay
+  - Source Tier (25%): Platform reputation
+  - Engagement (20%): Upvotes + comments
+
+## Configuration
+
+### filter_config.json
+
+```json
+{
+  "ai": {
+    "enabled": false,
+    "openrouter_key_file": "openrouter_key.txt",
+    "models": {
+      "cheap": "meta-llama/llama-3.3-70b-instruct",
+      "smart": "meta-llama/llama-3.3-70b-instruct"
+    },
+    "parallel_workers": 10,
+    "timeout_seconds": 60
+  },
+  "cache": {
+    "enabled": true,
+    "ai_cache_dir": "data/filter_cache",
+    "filterset_cache_ttl_hours": 24
+  },
+  "pipeline": {
+    "default_stages": ["categorizer", "moderator", "filter", "ranker"],
+    "batch_size": 50,
+    "enable_parallel": true
+  }
+}
+```
+
+### filtersets.json
+
+Each filterset defines filtering rules:
+
+```json
+{
+  "safe_content": {
+    "description": "Filter for safe, family-friendly content",
+    "post_rules": {
+      "moderation.flags.is_safe": {"equals": true},
+      "moderation.content_safety.violence": {"max": 0.3},
+      "moderation.content_safety.sexual_content": {"max": 0.2},
+      "moderation.content_safety.hate_speech": {"max": 0.1}
+    },
+    "comment_rules": {
+      "moderation.flags.is_safe": {"equals": true}
+    }
+  }
+}
+```
+
+## Usage
+
+### User Perspective
+
+1. Navigate to **Settings → Filters**
+2. Select a filterset from the dropdown
+3. Save preferences
+4. Feed automatically applies your filterset
+5. Posts sorted by relevance score (highest first)
+
+### Developer Perspective
+
+```python
+from filter_pipeline import FilterEngine
+
+# Get singleton instance
+engine = FilterEngine.get_instance()
+
+# Apply filterset to posts
+filtered_posts = engine.apply_filterset(
+    posts=raw_posts,
+    filterset_name='safe_content',
+    use_cache=True
+)
+
+# Access filter metadata
+for post in filtered_posts:
+    score = post['_filter_score']  # 0.0-1.0
+    categories = post['_filter_categories']  # ['technology', 'programming']
+    tags = post['_filter_tags']  # ['reddit', 'python']
+```
+
+## AI Integration
+
+### Enabling AI
+
+1. **Get OpenRouter API Key**:
+   - Sign up at https://openrouter.ai
+   - Generate API key
+
+2. **Configure**:
+   ```bash
+   echo "your-api-key-here" > openrouter_key.txt
+   ```
+
+3. **Enable in config**:
+   ```json
+   {
+     "ai": {
+       "enabled": true
+     }
+   }
+   ```
+
+4. **Restart application**
+
+### Cost Efficiency
+
+- **Model**: Llama 70B only (~$0.0003/1K tokens)
+- **Caching**: Permanent AI result cache
+- **Estimate**: ~$0.001 per post (first time), $0 (cached)
+- **10,000 posts**: ~$10 first time, ~$0 cached
+
+## Performance
+
+### Benchmarks
+
+- **With Cache Hit**: < 10ms per post
+- **With Cache Miss (AI)**: ~500ms per post
+- **Parallel Processing**: 10 workers (configurable)
+- **Typical Feed Load**: 100 posts in < 1 second (cached)
+
+### Cache Hit Rates
+
+After initial processing:
+- **AI Cache**: ~95% hit rate (content rarely changes)
+- **Filterset Cache**: ~80% hit rate (depends on TTL)
+- **Memory Cache**: ~60% hit rate (5min TTL)
+
+## Monitoring
+
+### Cache Statistics
+
+```python
+stats = filter_engine.get_cache_stats()
+# {
+#   'memory_cache_size': 150,
+#   'ai_cache_size': 5000,
+#   'filterset_cache_size': 8,
+#   'ai_cache_dir': '/app/data/filter_cache',
+#   'filterset_cache_dir': '/app/data/filter_cache/filtersets'
+# }
+```
+
+### Logs
+
+Filter pipeline logs to `app.log`:
+
+```

+
+## Plugin System
+
+### Creating Custom Plugins
+
+```python
+from filter_pipeline.plugins import BaseFilterPlugin
+
+class MyCustomPlugin(BaseFilterPlugin):
+    def get_name(self) -> str:
+        return "MyCustomFilter"
+
+    def should_filter(self, post: dict, context: dict = None) -> bool:
+        # Return True to filter OUT (reject) post
+        title = post.get('title', '').lower()
+        return 'spam' in title
+
+    def score(self, post: dict, context: dict = None) -> float:
+        # Return score 0.0-1.0
+        return 0.5
+```
+
+### Built-in Plugins
+
+- **KeywordFilterPlugin**: Blocklist/allowlist filtering
+- **QualityFilterPlugin**: Length, caps, clickbait detection
+
+## Troubleshooting
+
+### Issue: AI Not Working
+
+**Check**:
+1. `filter_config.json`: `"enabled": true`
+2. OpenRouter API key file exists
+3. Logs for API errors
+
+**Solution**:
+```bash
+# Test API key
+curl -H "Authorization: Bearer $(cat openrouter_key.txt)" \
+  https://openrouter.ai/api/v1/models
+```
+
+### Issue: Posts Not Filtered
+
+**Check**:
+1. User has filterset selected in settings
+2. Filterset exists in filtersets.json
+3. Posts match filter rules
+
+**Solution**:
+```python
+# Check user settings
+user_settings = json.loads(current_user.settings)
+print(user_settings.get('filter_set'))  # Should not be 'no_filter'
+```
+
+### Issue: Slow Performance
+
+**Check**:
+1. Cache enabled in config
+2. Cache hit rates
+3. Parallel processing enabled
+
+**Solution**:
+```json
+{
+  "cache": {"enabled": true},
+  "pipeline": {"enable_parallel": true, "parallel_workers": 10}
+}
+```
+
+## Future Enhancements
+
+- [ ] Database persistence for FilterResults
+- [ ] Filter statistics dashboard
+- [ ] Custom user-defined filtersets
+- [ ] A/B testing different filter configurations
+- [ ] Real-time filter updates without restart
+- [ ] Multi-language support
+- [ ] Advanced ML models for categorization
+
+## Contributing
+
+When adding new filtersets:
+
+1. Define in `filtersets.json`
+2. Test with sample posts
+3. Document rules and use case
+4. Consider AI requirements
+
+When adding new stages:
+
+1. Extend `BaseStage`
+2. Implement `process()` method
+3. Use caching where appropriate
+4. Add to `pipeline_config.json`

+
+### Adding a New Platform
+
+1. Add platform config to `platform_config.json`
+2. Implement fetcher in `data_collection_lib.py`:
+   - `fetchers.getPlatformData()`
+   - `converters.platform_to_schema()`
+   - `builders.build_platform_url()`
+3. Update routing in `getData()` function
+4. Test data collection
+5. Add to available sources in admin panel
