+  - Image field absent (not null) when no media attached
+  - Both feed formats maintain existing HTML embedding for universal reader support
+  - Provides enhanced display in modern feed readers (Feedly, Inoreader, NetNewsWire)
+
+- **Custom Slug Input Field** - Web UI now supports custom slugs (v1.2.0 Phase 1)
+  - Added optional custom slug field to note creation form
+  - Slugs are read-only after creation to preserve permalinks
+  - Auto-validates and sanitizes slug format (lowercase, numbers, hyphens only)
+  - Shows helpful placeholder text and validation guidance
+  - Matches Micropub `mp-slug` behavior for consistency
+  - Falls back to auto-generation when field is left blank
+
+- **Author Profile Discovery** - Automatic h-card discovery from IndieAuth identity (v1.2.0 Phase 2)
+  - Discovers author information from user's IndieAuth profile URL on login
+  - Caches author h-card data (name, photo, bio, rel-me links) for 24 hours
+  - Uses mf2py library for reliable Microformats2 parsing
+  - Graceful fallback to domain name if discovery fails
+  - Never blocks login functionality (per ADR-061)
+  - Eliminates need for manual author configuration
+
+- **Complete Microformats2 Support** - Full IndieWeb h-entry, h-card, h-feed markup (v1.2.0 Phase 2)
+  - All notes display as proper h-entry with required properties (u-url, dt-published, e-content, p-author)

+  - UUID-based filenames prevent collisions
+  - Media included in all syndication feeds (RSS, ATOM, JSON Feed)
+  - RSS: HTML embedding in description
+  - ATOM: Both enclosures and HTML content
+  - JSON Feed: Native attachments array
+  - Multiple u-photo properties in Microformats2 markup
+  - Media files cached immutably (1 year) for performance
+
+### Fixed
+- **Media Display on Homepage** - Images now display correctly on homepage, not just individual note pages
+- **Responsive Image Sizing** - Images constrained to container width with proper CSS
+- **Caption Display** - Captions now used as alt text only, not displayed as visible text
+- **Logging Correlation ID** - Fixed crash in non-request contexts (app init, memory monitor)
+
+## [1.1.2] - 2025-11-28
+
+### Fixed
+- **CRITICAL**: Static files now load correctly - fixed HTTP middleware streaming response handling
+  - HTTP metrics middleware was accessing `.data` on streaming responses (Flask's `send_from_directory`)
+  - This caused RuntimeError: "Attempted implicit sequence conversion but the response object is in direct passthrough mode"
+  - Now checks `direct_passthrough` attribute before accessing response data
+  - Gracefully falls back to `content_length` for streaming responses
+  - Fixes complete site failure (no CSS/JS loading)
+
+- **HIGH**: Database metrics now display correctly - fixed configuration key mismatch
+  - Config sets `METRICS_SAMPLING_RATE` (singular), metrics read `METRICS_SAMPLING_RATES` (plural)
+  - Mismatch caused fallback to hardcoded 10% sampling regardless of config
+  - Fixed key to use `METRICS_SAMPLING_RATE` (singular) consistently
+  - MetricsBuffer now accepts both float (global rate) and dict (per-type rates)
+  - Increased default sampling rate from 10% to 100% for low-traffic sites
+
+### Changed
+- Default metrics sampling rate increased from 10% to 100%
+  - Better visibility for low-traffic single-user deployments
+  - Configurable via `METRICS_SAMPLING_RATE` environment variable (0.0-1.0)
+  - Minimal overhead at typical usage levels
+  - Power users can reduce if needed

+# v1.1.1 Performance Monitoring Instrumentation Assessment
+
+## Architectural Finding
+
+**Date**: 2025-11-25
+**Architect**: StarPunk Architect
+**Subject**: Missing Performance Monitoring Instrumentation
+**Version**: v1.1.1-rc.2
+
+## Executive Summary
+
+**VERDICT: IMPLEMENTATION BUG - Critical instrumentation was not implemented**
+
+The performance monitoring infrastructure exists but lacks the actual instrumentation code to collect metrics. This represents an incomplete implementation of the v1.1.1 design specifications.
+
+## Evidence
+
+### 1. Design Documents Clearly Specify Instrumentation
+
+#### Performance Monitoring Specification (performance-monitoring-spec.md)
+Lines 141-232 explicitly detail three types of instrumentation:
+- **Database Query Monitoring** (lines 143-195)
+- **HTTP Request Monitoring** (lines 197-232)
+- **Memory Monitoring** (lines 234-276)
+
+Example from specification:
+```python
+# Line 165: "Execute query (via monkey-patching)"
+def monitored_execute(sql, params=None):
+    result = original_execute(sql, params)
+    duration = time.perf_counter() - start_time
+
+    metric = PerformanceMetric(...)
+    metrics_buffer.add_metric(metric)
+```
+
+#### Developer Q&A Documentation
+**Q6** (lines 93-107): Explicitly discusses per-process buffers and instrumentation
+**Q12** (lines 193-205): Details sampling rates for "database/http/render" operations
+
+Quote from Q&A:
+> "Different rates for database/http/render... Use random sampling at collection point"
+
+#### ADR-053 Performance Monitoring Strategy
+Lines 200-220 specify instrumentation points:
+> "1. **Database Layer**
+>    - All queries automatically timed
+>    - Connection acquisition/release
+>    - Transaction duration"
+>
+> "2. **HTTP Layer**
+>    - Middleware wraps all requests
+>    - Per-endpoint timing"
+
+### 2. Current Implementation Status
+
+#### What EXISTS (✅)
+- `starpunk/monitoring/metrics.py` - MetricsBuffer class
+- `record_metric()` function - Fully implemented
+- `/admin/metrics` endpoint - Working
+- Dashboard UI - Rendering correctly
+
+#### What's MISSING (❌)
+- **ZERO calls to `record_metric()`** in the entire codebase
+- No HTTP request timing middleware
+- No database query instrumentation
+- No memory monitoring thread
+- No automatic metric collection
+
+### 3. Grep Analysis Results
+
+```bash
+# Search for record_metric calls (excluding definition)
+$ grep -r "record_metric" --include="*.py" | grep -v "def record_metric"
+# Result: Only imports and docstring examples, NO actual calls
+
+# Search for timing code
+$ grep -r "time.perf_counter\|track_query"
+# Result: No timing instrumentation found
+
+# Check middleware
+$ grep "@app.after_request"
+# Result: No after_request handler for timing
+```
+
+### 4. Phase 2 Implementation Report Claims
+
+The Phase 2 report (line 22-23) states:
+> "Performance Monitoring Infrastructure - Status: ✅ COMPLETED"
+
+But line 89 reveals the truth:
+> "API: record_metric('database', 'SELECT notes', 45.2, {'query': 'SELECT * FROM notes'})"
+
+This is an API example, not actual instrumentation code.
+
+## Root Cause Analysis
+
+The developer implemented the **monitoring framework** (the "plumbing") but not the **instrumentation code** (the "sensors"). This is like installing a dashboard in a car but not connecting any of the gauges to the engine.
+
+### Why This Happened
+
+1. **Misinterpretation**: Developer may have interpreted "monitoring infrastructure" as just the data structures and endpoints
+2. **Documentation Gap**: The Phase 2 report focuses on the API but doesn't show actual integration
+3. **Testing Gap**: No tests verify that metrics are actually being collected
+
+## Impact Assessment
+
+### User Impact
+- Dashboard shows all zeros (confusing UX)
+- No performance visibility as designed
+- Feature appears broken
+
+### Technical Impact
+- Core functionality works (no crashes)
+- Performance overhead is actually ZERO (ironically meeting the <1% target)
+- Easy to fix - framework is ready
+
+## Architectural Recommendation
+
+**Recommendation: Fix in v1.1.2 (not blocking v1.1.1)**
+
+### Rationale
+
+1. **Not a Breaking Bug**: System functions correctly, just lacks metrics
+2. **Documentation Exists**: Can document as "known limitation"
+3. **Clean Fix Path**: v1.1.2 can add instrumentation without structural changes
+4. **Version Strategy**: v1.1.1 focused on "Polish" - this is more "Observability"
+
+### Alternative: Hotfix Now
+
+If you decide this is critical for v1.1.1:
+- Create v1.1.1-rc.3 with instrumentation
+- Estimated effort: 2-4 hours
+- Risk: Low (additive changes only)
+
+## Required Instrumentation (for v1.1.2)
+
+### 1. HTTP Request Timing
+```python
+# In starpunk/__init__.py
+@app.before_request
+def start_timer():
+    if app.config.get('METRICS_ENABLED'):
+        g.start_time = time.perf_counter()
+
+@app.after_request
+def end_timer(response):
+    if hasattr(g, 'start_time'):
+        duration = time.perf_counter() - g.start_time
+        record_metric('http', request.endpoint, duration * 1000)
+    return response
+```
+
+### 2. Database Query Monitoring
+Wrap `get_connection()` or instrument execute() calls
+
+### 3. Memory Monitoring Thread
+Start background thread in app factory
+
+## Conclusion
+
+This is a **clear implementation gap** between design and execution. The v1.1.1 specifications explicitly required instrumentation that was never implemented. However, since the monitoring framework itself is complete and the system is otherwise stable, this can be addressed in v1.1.2 without blocking the current release.
+
+The developer delivered the "monitoring system" but not the "monitoring integration" - a subtle but critical distinction that the architecture documents did specify.
+
+## Decision Record
+
+Create ADR-056 documenting this as technical debt:
+- Title: "Deferred Performance Instrumentation to v1.1.2"
+- Status: Accepted
+- Context: Monitoring framework complete but lacks instrumentation
+- Decision: Ship v1.1.1 with framework, add instrumentation in v1.1.2
+- Consequences: Dashboard shows zeros until v1.1.2

+
+### Data Flow
+
+1. **Request Processing**
+   - Client sends HTTP request with Accept header
+   - Content negotiator determines optimal format
+   - Check cache for existing feed
+
+2. **Feed Generation**
+   - If cache miss, fetch notes from database
+   - Generate feed using appropriate generator
+   - Stream response to client
+   - Update cache asynchronously
+
+3. **Metrics Collection**
+   - Record request timing
+   - Track cache hit/miss rates
+   - Monitor generation performance
+   - Log format popularity
+
+## Key Components
+
+### 1. Metrics Instrumentation Layer
+
+**Purpose**: Complete visibility into all system operations
+
+**Components**:
+- Database operation timing (all queries)
+- HTTP request/response metrics
+- Memory monitoring thread
+- Business metrics (syndication stats)
+
+**Integration Points**:
+- Database connection wrapper
+- Flask middleware hooks
+- Background thread for memory
+- Feed generation decorators
+
+### 2. Content Negotiation Service
+
+**Purpose**: Determine optimal feed format based on client preferences
+
+**Algorithm**:
+```
+1. Parse Accept header
+2. Score each format:
+   - Exact match: 1.0
+   - Wildcard match: 0.5
+   - No match: 0.0
+3. Consider quality factors (q=)
+4. Return highest scoring format
+5. Default to RSS if no preference
+```
+
+**Supported MIME Types**:
+- RSS: `application/rss+xml`, `application/xml`, `text/xml`
+- ATOM: `application/atom+xml`
+- JSON: `application/json`, `application/feed+json`
+
+### 3. Feed Generators
+
+**Shared Interface**:
+```python
+class FeedGenerator(Protocol):
+    def generate(self, notes: List[Note], config: FeedConfig) -> Iterator[str]:
+        """Generate feed chunks"""
+
+    def validate(self, feed_content: str) -> List[ValidationError]:
+        """Validate generated feed"""
+```
+
+**RSS Generator** (existing, enhanced):
+- RSS 2.0 specification
+- Streaming generation
+- CDATA wrapping for HTML
+
+**ATOM Generator** (new):
+- ATOM 1.0 specification
+- RFC 3339 date formatting
+- Author metadata support
+- Category/tag support
+
+**JSON Feed Generator** (new):
+- JSON Feed 1.1 specification
+- Attachment support for media
+- Author object with avatar
+- Hub support for real-time
+
+### 4. Feed Cache System
+
+**Purpose**: Minimize regeneration overhead
+
+**Design**:
+- LRU cache with configurable size
+- TTL-based expiration (default: 5 minutes)
+- Format-specific cache keys
+- Invalidation on note changes
+
+**Cache Key Structure**:
+```
+feed:{format}:{limit}:{checksum}
+```
+
+Where checksum is based on:
+- Latest note timestamp
+- Total note count
+- Site configuration
+
+### 5. Statistics Dashboard
+
+**Purpose**: Track syndication performance and usage
+
+**Metrics Tracked**:
+- Feed requests by format
+- Cache hit rates
+- Generation times
+- Client user agents
+- Geographic distribution (via IP)
+
+**Dashboard Location**: `/admin/syndication`
+
+### 6. OPML Export
+
+**Purpose**: Allow users to share their feed collection
+
+**Implementation**:
+- Generate OPML 2.0 document
+- Include all available feed formats
+- Add metadata (title, owner, date)
+
+## Performance Considerations
+
+### Memory Management
+
+**Streaming Generation**:
+- Generate feeds in chunks
+- Yield results incrementally
+- Avoid loading all notes at once
+- Use generators throughout
+
+**Cache Sizing**:
+- Monitor memory usage
+- Implement cache eviction
+- Configurable cache limits
+
+### Database Optimization
+
+**Query Optimization**:
+- Index on published status
+- Index on created_at for ordering
+- Limit fetched columns
+- Use prepared statements
+
+**Connection Pooling**:
+- Reuse database connections
+- Monitor pool usage
+- Track connection wait times
+
+### HTTP Optimization
+
+**Compression**:
+- gzip for text formats (RSS, ATOM)
+- Already compact JSON Feed
+- Configurable compression level
+
+**Caching Headers**:
+- ETag based on content hash
+- Last-Modified from latest note
+- Cache-Control with max-age
+
+## Security Considerations
+
+### Input Validation
+
+- Validate Accept headers
+- Sanitize format parameters
+- Limit feed size
+- Rate limit feed endpoints
+
+### Content Security
+
+- Escape XML entities properly
+- Valid JSON encoding
+- No script injection in feeds
+- CORS headers for JSON feeds
+
+### Resource Protection
+
+- Rate limiting per IP
+- Maximum feed items limit
+- Timeout for generation
+- Circuit breaker for database
+
+## Configuration
+
+### Feed Settings
+
+```ini
+# Feed generation
+STARPUNK_FEED_DEFAULT_LIMIT = 50
+STARPUNK_FEED_MAX_LIMIT = 500
+STARPUNK_FEED_CACHE_TTL = 300  # seconds

+- Request timeouts
+- Rate limiting
+
+### Compatibility Risks
+
+**Risk**: Feed readers reject new formats
+**Mitigation**:
+- Extensive testing with readers
+- Strict spec compliance
+- Format validation
+- Fallback to RSS
+
+### Operational Risks
+
+**Risk**: Cache grows unbounded
+**Mitigation**:
+- LRU eviction
+- Size limits
+- Memory monitoring
+- Auto-cleanup
+
+## Conclusion
+
+StarPunk v1.1.2 "Syndicate" creates a robust, standards-compliant syndication platform while completing the observability foundation started in v1.1.1. The architecture prioritizes performance through streaming and caching, compatibility through strict standards adherence, and maintainability through clean component separation.
+

+# ADR-056: Use External IndieAuth Provider (Never Self-Host)
+
+## Status
+**ACCEPTED** - This is a permanent, non-negotiable decision.
+
+## Context
+StarPunk is a minimal IndieWeb CMS focused on **content creation and syndication**, not identity infrastructure. The project philosophy demands that every line of code must justify its existence.
+
+The question of whether to implement self-hosted IndieAuth has been raised multiple times. This ADR documents the final, permanent decision on this matter.
+
+## Decision
+**StarPunk will NEVER implement self-hosted IndieAuth.**
+
+We will always rely on external IndieAuth providers such as:
+- indielogin.com (primary recommendation)
+- Other established IndieAuth providers
+
+This decision is **permanent and non-negotiable**.
+
+## Rationale
+
+### 1. Project Focus
+StarPunk's mission is to be a minimal CMS for publishing IndieWeb content. Our core competencies are:
+- Publishing notes with proper microformats
+- Generating RSS/Atom/JSON feeds
+- Implementing Micropub for content creation
+- Media management for content
+
+Identity infrastructure is explicitly **NOT** our focus.
+
+### 2. Complexity vs Value
+Implementing IndieAuth would require:
+- OAuth 2.0 implementation
+- Token management
+- Security considerations
+- Key storage and rotation
+- User profile management
+- Authorization code flows
+
+This represents hundreds or thousands of lines of code that don't serve our core mission of content publishing.
+
+### 3. Existing Solutions Work
+External IndieAuth providers like indielogin.com:
+- Are battle-tested
+- Handle security updates
+- Support multiple authentication methods
+- Are free to use
+- Align with IndieWeb principles of building on existing infrastructure
+
+### 4. Philosophy Alignment
+Our core philosophy states: "Every line of code must justify its existence. When in doubt, leave it out."
+
+Self-hosted IndieAuth cannot justify its existence in a minimal content-focused CMS.
+
+## Consequences
+
+### Positive
+- Dramatically reduced codebase complexity
+- No security burden for identity management
+- Faster development of content features
+- Clear project boundaries
+- User authentication "just works" via proven providers
+
+### Negative
+- Dependency on external service (indielogin.com)
+- Cannot function without internet connection to auth provider
+- No control over authentication user experience
+
+### Mitigations
+- Document clear setup instructions for using indielogin.com
+- Support multiple external providers for redundancy
+- Cache authentication tokens appropriately
+
+## Alternatives Considered
+
+### 1. Self-Hosted IndieAuth (REJECTED)
+**Why considered:** Full control over authentication
+**Why rejected:** Massive scope creep, violates project philosophy
+
+### 2. No Authentication (REJECTED)
+**Why considered:** Ultimate simplicity
+**Why rejected:** Single-user system still needs access control
+
+### 3. Basic Auth or Simple Password (REJECTED)
+**Why considered:** Very simple to implement
+**Why rejected:** Not IndieWeb compliant, poor user experience
+
+### 4. Hybrid Approach (REJECTED)
+**Why considered:** Optional self-hosted with external fallback
+**Why rejected:** Maintains complexity we're trying to avoid
+
+## Implementation Notes
+
+All authentication code should:
+1. Assume an external IndieAuth provider
+2. Never include hooks or abstractions for self-hosting
+3. Document indielogin.com as the recommended provider
+4. Include clear error messages when auth provider is unavailable
+
+## References
+- Project Philosophy: "Every line of code must justify its existence"

+
+## Final Note
+This decision has been made after extensive consideration and multiple discussions. It is final.
+
+**Do not propose self-hosted IndieAuth in future architectural discussions.**
+
+The goal of StarPunk is **content**, not **identity**.

+# ADR-057: Media Attachment Model
+
+## Status
+Accepted
+
+## Context
+The v1.2.0 media upload feature needed a clear model for how media relates to notes. Initial design assumed inline markdown image insertion (like a blog editor), but user feedback clarified that notes are more like social media posts (tweets, Mastodon toots) where media is attached rather than inline.
+
+Key insights from user:
+- "Notes are more like tweets, thread posts, mastodon posts etc. where the media is inserted is kind of irrelevant"
+- Media should appear at the TOP of notes when displayed
+- Text content should appear BELOW media
+- Multiple images per note should be supported
+
+## Decision
+We will implement a social media-style attachment model for media:
+
+1. **Database Design**: Use a junction table (`note_media`) to associate media files with notes, allowing:
+   - Multiple media per note (max 4)
+   - Explicit ordering via `display_order` column
+   - Per-attachment metadata (captions)
+   - Future reuse of media across notes
+
+2. **Display Model**: Media attachments appear at the TOP of notes:
+   - 1 image: Full width display
+   - 2 images: Side-by-side layout
+   - 3-4 images: Grid layout
+   - Text content always appears below media
+
+3. **Syndication Strategy**:
+   - RSS: Embed media as HTML in description (universal support)
+   - ATOM: Use both `<link rel="enclosure">` and HTML content
+   - JSON Feed: Use native `attachments` array (cleanest)
+
+4. **Microformats2**: Multiple `u-photo` properties for multi-photo posts
+
+## Rationale
+**Why attachment model over inline markdown?**
+- Matches user mental model (social media posts)
+- Simplifies UI/UX (no cursor tracking needed)
+- Better syndication support (especially JSON Feed)
+- Cleaner Microformats2 markup
+- Consistent display across all contexts
+
+**Why junction table over array column?**
+- Better query performance for feeds
+- Supports future media reuse
+- Per-attachment metadata
+- Explicit ordering control
+- Standard relational design
+
+**Why limit to 4 images?**
+- Twitter limit is 4 images
+- Mastodon limit is 4 images
+- Prevents performance issues
+- Maintains clean grid layouts
+- Sufficient for microblogging use case
+
+## Consequences
+
+### Positive
+- Clean separation of media and text content
+- Familiar social media UX pattern
+- Excellent syndication feed support
+- Future-proof for media galleries
+- Supports accessibility via captions
+- Efficient database queries
+
+### Negative
+- No inline images in markdown content
+- All media must appear at top
+- Cannot mix text and images
+- More complex database schema
+- Additional JOIN queries needed
+
+### Neutral
+- Different from traditional blog CMSs
+- Requires grid layout CSS
+- Media upload is separate from text editing
+
+## Alternatives Considered
+
+### Alternative 1: Inline Markdown Images
+Store media URLs in markdown content as `![alt](url)`.
+- **Pros**: Traditional blog approach, flexible positioning
+- **Cons**: Poor syndication, complex editing UX, inconsistent display
+
+### Alternative 2: JSON Array in Notes Table
+Store media IDs as JSON array column in notes table.
+- **Pros**: Simpler schema, fewer tables
+- **Cons**: Poor query performance, no per-media metadata, violates 1NF
+
+### Alternative 3: Single Media Per Note
+Restrict to one image per note.
+- **Pros**: Simplest implementation
+- **Cons**: Too limiting, doesn't match social media patterns
+
+## Implementation Notes
+
+1. Migration will create both `media` and `note_media` tables
+2. Feed generators must query media via JOIN
+3. Template must render media before content
+4. Upload UI shows thumbnails, not markdown insertion
+5. Consider lazy loading for performance

+# ADR-058: Image Optimization Strategy
+
+## Status
+Accepted
+
+## Context
+The v1.2.0 media upload feature requires decisions about image size limits, optimization, and validation. Based on user requirements:
+- 4 images maximum per note (confirmed)
+- No drag-and-drop reordering needed (display order is upload order)
+- Image optimization desired
+- Optional caption field for each image (accessibility)
+
+Research was conducted on:
+- Web image best practices (2024)
+- IndieWeb implementation patterns
+- Python image processing libraries
+- Storage implications for single-user CMS
+
+## Decision
+
+### Image Limits
+We will enforce the following limits:
+
+1. **Count**: Maximum 4 images per note
+2. **File Size**: Maximum 10MB per image
+3. **Dimensions**: Maximum 4096x4096 pixels
+4. **Formats**: JPEG, PNG, GIF, WebP only
+
+### Optimization Strategy
+We will implement **automatic resizing on upload**:
+
+1. **Resize Policy**:
+   - Images larger than 2048 pixels (longest edge) will be resized
+   - Aspect ratio will be preserved
+   - Original quality will be maintained (no aggressive compression)
+   - EXIF orientation will be corrected
+
+2. **Rejection Policy**:
+   - Files over 10MB will be rejected (before optimization)
+   - Dimensions over 4096x4096 will be rejected
+   - Invalid formats will be rejected
+   - Corrupted files will be rejected
+
+3. **Processing Library**: Use **Pillow** for image processing
+
+### Database Schema Updates
+Add caption field to `note_media` table:
+```sql
+CREATE TABLE note_media (
+    id INTEGER PRIMARY KEY,
+    note_id INTEGER NOT NULL,
+    media_id INTEGER NOT NULL,
+    display_order INTEGER NOT NULL DEFAULT 0,
+    caption TEXT,  -- Optional caption for accessibility
+    created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    FOREIGN KEY (note_id) REFERENCES notes(id) ON DELETE CASCADE,
+    FOREIGN KEY (media_id) REFERENCES media(id) ON DELETE CASCADE,
+    UNIQUE(note_id, media_id)
+);
+```
+
+## Rationale
+
+### Why 10MB file size limit?
+- Generous for high-quality photos from modern phones
+- Prevents storage abuse on single-user instance
+- Reasonable upload time even on slower connections
+- Matches or exceeds most social platforms
+
+### Why 4096x4096 max dimensions?
+- Covers 16-megapixel images (4000x4000)
+- Sufficient for 4K displays (3840x2160)
+- Prevents memory issues during processing
+- Larger than needed for web display
+
+### Why resize to 2048px?
+- Optimal balance between quality and performance
+- Retina-ready (2x scaling on 1024px display)
+- Significant file size reduction
+- Matches common social media limits
+- Preserves quality for most use cases
+
+### Why Pillow over alternatives?
+- De-facto standard for Python image processing
+- Fastest for basic resize operations
+- Minimal dependencies
+- Well-documented and stable
+- Sufficient for our needs (resize, format conversion, EXIF)
+
+### Why automatic optimization?
+- Better user experience (no manual intervention)
+- Consistent output quality
+- Storage efficiency
+- Faster page loads
+- Users still get good quality
+
+### Why no thumbnail generation?
+- Adds complexity for minimal benefit
+- Modern browsers handle image scaling well
+- Single-user CMS doesn't need CDN optimization
+- Can be added later if needed
+
+## Consequences
+
+### Positive
+- Automatic optimization improves performance
+- Generous limits support high-quality photography
+- Captions improve accessibility
+- Storage usage remains reasonable
+- Fast processing with Pillow
+
+### Negative
+- Users cannot upload raw/unprocessed images
+- Some quality loss for images over 2048px
+- No manual control over optimization
+- Additional processing time on upload
+
+### Neutral
+- Requires Pillow dependency
+- Images stored at single resolution
+- No progressive enhancement (thumbnails)
+
+## Alternatives Considered
+
+### Alternative 1: No Optimization
+Accept images as-is, no processing.
+- **Pros**: Simpler, preserves originals
+- **Cons**: Storage bloat, slow page loads, memory issues
+
+### Alternative 2: Strict Limits (1MB, 1920x1080)
+Match typical web recommendations.
+- **Pros**: Optimal performance, minimal storage
+- **Cons**: Too restrictive for photography, poor UX
+
+### Alternative 3: Generate Multiple Sizes
+Create thumbnail, medium, and full sizes.
+- **Pros**: Optimal delivery, responsive images
+- **Cons**: Complex implementation, 3x storage, overkill for single-user
+
+### Alternative 4: Client-side Resizing
+Resize in browser before upload.
+- **Pros**: Reduces server load
+- **Cons**: Inconsistent quality, browser limitations, poor UX
+
+## Implementation Notes
+
+1. **Validation Order**:
+   - Check file size (reject if >10MB)
+   - Check MIME type (accept only allowed formats)
+   - Load with Pillow (validates file integrity)
+   - Check dimensions (reject if >4096px)
+   - Resize if needed (>2048px)
+   - Save optimized version
+
+2. **Error Messages**:
+   - "File too large. Maximum size is 10MB"
+   - "Invalid image format. Accepted: JPEG, PNG, GIF, WebP"
+   - "Image dimensions too large. Maximum is 4096x4096"
+   - "Image appears to be corrupted"
+
+3. **Pillow Configuration**:
+   ```python
+   # Preserve quality during resize
+   image.thumbnail((2048, 2048), Image.Resampling.LANCZOS)
+
+   # Correct EXIF orientation
+   ImageOps.exif_transpose(image)
+
+   # Save with original quality
+   image.save(output, quality=95, optimize=True)
+   ```
+
+4. **Caption Implementation**:
+   - Add caption field to upload form
+   - Store in `note_media.caption`
+   - Use as alt text in HTML
+   - Include in Microformats markup

+  </media:group>
+  <media:thumbnail url="thumb.jpg" width="150" height="150" />
+  ```
+
+- JSON Feed: Use `image` for default, include variants in `_starpunk` extension
+
+**Database Changes**:
+- `media_variants` table: media_id, variant_type, path, width, height, size_bytes
+- Add `has_variants` boolean to `media` table
+
+**Effort Estimate**: 8-12 hours
+
+### 5. Full JSON Feed 1.1 Media Compliance
+
+**Research Required**: JSON Feed 1.1 specification for extensions
+
+**Implementation Scope**:
+- Top-level `image` field (URL of first image, per spec)
+- Top-level `banner_image` if applicable
+- Item-level `image` field (main/featured image)
+- Item-level `banner_image` for posts with banners
+- Complete `attachments` array:
+  ```json
+  {
+    "url": "https://example.com/media/image.jpg",
+    "mime_type": "image/jpeg",
+    "title": "Image caption",
+    "size_in_bytes": 245760,
+    "duration_in_seconds": null
+  }
+  ```
+- Audio attachments with `duration_in_seconds`
+- Video attachments (if supported)
+
+**Effort Estimate**: 4-6 hours
+
+### 6. ATOM Feed Media Extensions
+
+**Research Required**:
+- ATOM Media extension namespace
+- `<link rel="enclosure">` best practices
+
+**Implementation Scope**:
+- `<link rel="enclosure">` for each media item
+- `type` attribute with MIME type
+- `length` attribute with file size
+- `title` attribute with caption
+- Consider `<link rel="related">` for thumbnails
+
+**Effort Estimate**: 3-5 hours
+
+## Total Effort Estimate
+
+| Feature | Minimum | Maximum |
+|---------|---------|---------|
+| Complete Media RSS | 8 hours | 12 hours |
+| Podcast RSS Support | 10 hours | 16 hours |
+| Video Support | 16 hours | 24 hours |
+| Multiple Image Sizes | 8 hours | 12 hours |
+| JSON Feed Compliance | 4 hours | 6 hours |
+| ATOM Extensions | 3 hours | 5 hours |
+| **Total** | **49 hours** | **75 hours** |
+
+**Note**: Video support is the most complex feature and could be deferred to v1.4.0 "Media" release.
+
+## Prerequisites
+
+Before implementing Full Standardization:
+
+1. **Option 2 Complete**: Basic Media RSS and JSON Feed `image` field
+2. **Image Optimization**: ADR-058 image optimization strategy implemented
+3. **Media Storage Architecture**: Clear path for large file storage
+4. **Test Infrastructure**: Feed validation tests in place
+
+## Implementation Phases
+
+### Phase A: Enhanced Image Support (v1.3.0)
+- Multiple image sizes/thumbnails
+- Full Media RSS for images
+- Enhanced JSON Feed attachments
+- **Effort**: 12-18 hours
+
+### Phase B: Audio Support (v1.3.x or v1.4.0)
+- Podcast RSS implementation
+- Audio duration extraction
+- iTunes namespace
+- **Effort**: 10-16 hours
+
+### Phase C: Video Support (v1.4.0 "Media")
+- Video upload handling
+- Poster generation
+- Video in feeds
+- **Effort**: 16-24 hours
+
+## Consequences
+
+### Positive
+- Best-in-class feed reader compatibility
+- Podcast distribution capability
+- Video content support
+- Professional media syndication
+- Future-proof architecture
+
+### Negative
+- Significant implementation effort (50-75 hours total)
+- Increased storage requirements
+- More complex feed generation
+- Processing overhead for image variants
+- Larger codebase to maintain
+
+### Neutral
+- Aligns with media-focused v1.4.0 roadmap
+- Phased implementation possible
+- Optional features can be configuration-gated
+
+## Alternatives Considered
+
+### Alternative 1: Minimal Enhancement (Option 2 Only)
+Just implement basic Media RSS and JSON Feed image field.
+- **Pros**: Low effort, immediate benefit
+- **Cons**: Misses podcast/video opportunity
+
+### Alternative 2: Third-Party Media Service
+Use external service (Cloudinary, etc.) for media processing.
+- **Pros**: Offloads complexity
+- **Cons**: External dependency, cost, data ownership concerns
+
+### Alternative 3: Plugin Architecture
+Make media support pluggable for advanced features.
+- **Pros**: Keeps core simple
+- **Cons**: Added architectural complexity

+# ADR-061: Author Profile Discovery from IndieAuth
+
+## Status
+Accepted
+
+## Context
+StarPunk v1.2.0 requires Microformats2 compliance, including proper h-card author information in h-entries. The original design assumed author information would be configured via environment variables (AUTHOR_NAME, AUTHOR_PHOTO, etc.).
+
+However, since StarPunk uses IndieAuth for authentication, and users authenticate with their domain/profile URL, we have an opportunity to discover author information directly from their IndieWeb profile rather than requiring manual configuration.
+
+The user explicitly stated: "These should be retrieved from the logged in profile domain (rel me etc.)" when asked about author configuration.
+
+## Decision
+Implement automatic author profile discovery from the IndieAuth 'me' URL:
+
+1. When a user logs in via IndieAuth, fetch their profile page
+2. Parse h-card microformats and rel-me links from the profile
+3. Cache this information in a new `author_profile` database table
+4. Use discovered information in templates for Microformats2 markup
+5. Provide fallback behavior when discovery fails
+
+## Rationale
+1. **IndieWeb Native**: Discovery from profile URLs is a core IndieWeb pattern
+2. **DRY Principle**: Author already maintains their profile; no need to duplicate
+3. **Dynamic Updates**: Profile changes are reflected on next login
+4. **Standards-Based**: Uses existing h-card and rel-me specifications
+5. **User Experience**: Zero configuration for author information
+6. **Consistency**: Author info always matches their IndieWeb identity
+
+## Consequences
+
+### Positive
+- No manual configuration of author information required
+- Automatically stays in sync with user's profile
+- Supports full IndieWeb identity model
+- Works with any IndieAuth provider
+- Discoverable rel-me links for identity verification
+
+### Negative
+- Requires network request during login (mitigated by caching)
+- Depends on proper markup on user's profile page
+- Additional database table required
+- More complex than static configuration
+- Parsing complexity for microformats
+
+### Implementation Details
+
+#### Database Schema
+```sql
+CREATE TABLE author_profile (
+    id INTEGER PRIMARY KEY,
+    me_url TEXT NOT NULL UNIQUE,
+    name TEXT,
+    photo TEXT,
+    bio TEXT,
+    rel_me_links TEXT,  -- JSON array
+    discovered_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+#### Discovery Flow
+1. User authenticates with IndieAuth
+2. On successful login, trigger discovery
+3. Fetch user's profile page (with timeout)
+4. Parse h-card for: name, photo, bio
+5. Parse rel-me links
+6. Store in database with timestamp
+7. Use cache for 7 days, refresh on login
+
+#### Fallback Strategy
+- If discovery fails during login, use cached data if available
+- If no cache exists, use minimal defaults (domain as name)
+- Never block login due to discovery failure
+- Log failures for monitoring
+
+## Alternatives Considered
+
+### 1. Environment Variables (Original Design)
+Static configuration via .env file
+- ✅ Simple, no network requests
+- ❌ Requires manual configuration
+- ❌ Duplicates information already on profile
+- ❌ Can become out of sync
+
+### 2. Hybrid Approach
+Environment variables with optional discovery
+- ✅ Flexibility for both approaches
+- ❌ More complex configuration
+- ❌ Unclear which takes precedence
+
+### 3. Discovery Only, No Cache
+Fetch profile on every request
+- ✅ Always up to date
+- ❌ Performance impact
+- ❌ Reliability issues
+
+### 4. Static Import Tool
+CLI command to import profile once
+- ✅ No runtime discovery needed
+- ❌ Manual process
+- ❌ Can become stale
+
+## Implementation Priority
+High - Required for v1.2.0 Microformats2 compliance

+# Feed Media Handling: Architecture Options Analysis
+
+**Date**: 2025-12-09
+**Author**: StarPunk Architect
+**Status**: Proposed
+**Related**: ADR-057, Q24, Q27, Q28
+
+## Executive Summary
+
+Analysis of the current feed output reveals that RSS 2.0 lacks proper media enclosure elements, while ATOM and JSON Feed have partial implementations. This document proposes three options for fixing media handling across all feed formats.
+
+## Current State Analysis
+
+### RSS Feed (Problem)
+```xml
+<item>
+  <title>Test</title>
+  <link>http://localhost:8000/note/with-a-test-slug</link>
+  <description>&lt;div class="media"&gt;&lt;img src="..." alt="Just some dude" /&gt;&lt;/div&gt;&lt;p&gt;Test&lt;/p&gt;</description>
+  <guid isPermaLink="true">http://localhost:8000/note/with-a-test-slug</guid>
+  <pubDate>Fri, 28 Nov 2025 23:23:13 +0000</pubDate>
+</item>
+```
+
+**Issues Identified**:
+1. No `<enclosure>` element for the image
+2. Image is only embedded as HTML in description
+3. Many feed readers (Feedly, Reeder) won't display the image prominently
+4. No `media:content` or `media:thumbnail` elements
+
+### ATOM Feed (Partial)
+```xml
+<entry>
+  <link rel="enclosure" type="image/jpeg" href="..." length="1796654"/>
+  <content type="html">...</content>
+</entry>
+```
+
+**Status**: Correctly includes enclosure link. ATOM implementation is acceptable.
+
+### JSON Feed (Partial)
+```json
+{
+  "attachments": [
+    {
+      "url": "...",
+      "mime_type": "image/jpeg",
+      "size_in_bytes": 1796654,
+      "title": "Just some dude"
+    }
+  ]
+}
+```
+
+**Issues Identified**:
+1. Has attachments array (correct per JSON Feed 1.1 spec)
+2. Missing top-level `image` field for featured image
+3. Some readers use `image` for thumbnail display
+
+## Standards Research Summary
+
+### RSS 2.0 Specification
+Per the [RSS 2.0 Specification](https://www.rssboard.org/rss-specification):
+- `<enclosure>` element requires: `url`, `length`, `type`
+- Only ONE enclosure per item is officially supported (though many readers accept multiple)
+- Images in `<description>` are fallback, not primary
+
+### Media RSS (MRSS) Extension
+Per the [Media RSS Specification](https://www.rssboard.org/media-rss):
+- Namespace: `http://search.yahoo.com/mrss/`
+- `<media:content>` for primary media with `medium="image"`
+- `<media:thumbnail>` for preview images
+- Provides richer metadata than basic enclosure
+
+### JSON Feed 1.1 Specification
+Per the [JSON Feed 1.1 spec](https://jsonfeed.org/version/1.1):
+- `image` field: URL of the main/featured image (for preview/thumbnail)
+- `attachments` array: Related resources (files, media)
+- Both can coexist - `image` for display, `attachments` for download
+
+### Feed Reader Compatibility Notes
+
+| Reader | Enclosure | media:content | HTML Images | Notes |
+|--------|-----------|---------------|-------------|-------|
+| Feedly | Good | Excellent | Fallback | Prefers media:thumbnail |
+| NetNewsWire | Good | Good | Yes | Displays HTML images inline |
+| Reeder | Good | Good | Yes | Uses enclosure for preview |
+| Inoreader | Good | Excellent | Yes | Full MRSS support |
+| FreshRSS | Good | Good | Yes | Displays all sources |
+| Feedbin | Good | Good | Yes | Clean HTML rendering |
+
+---
+
+## Option 1: RSS Enclosure Only (Minimal)
+
+### Description
+Add the standard RSS `<enclosure>` element to RSS feeds for the first image only, keeping HTML images in description as fallback.
+
+### Implementation Changes
+
+**File**: `/home/phil/Projects/starpunk/starpunk/feeds/rss.py`
+
+```python
+# In generate_rss() after setting description
+if hasattr(note, 'media') and note.media:
+    first_media = note.media[0]
+    media_url = f"{site_url}/media/{first_media['path']}"
+    fe.enclosure(
+        url=media_url,
+        length=str(first_media.get('size', 0)),
+        type=first_media.get('mime_type', 'image/jpeg')
+    )
+```
+
+**File**: `/home/phil/Projects/starpunk/starpunk/feeds/rss.py` (streaming version)
+
+```python
+# In generate_rss_streaming() item generation
+if hasattr(note, 'media') and note.media:
+    first_media = note.media[0]
+    media_url = f"{site_url}/media/{first_media['path']}"
+    mime_type = first_media.get('mime_type', 'image/jpeg')
+    size = first_media.get('size', 0)
+    yield f'      <enclosure url="{_escape_xml(media_url)}" length="{size}" type="{mime_type}"/>\n'
+```
+
+### Pros
+1. **Simplest implementation** - Single element addition
+2. **Spec-compliant** - Pure RSS 2.0, no extensions
+3. **Wide compatibility** - All RSS readers support enclosure
+4. **Low risk** - Minimal code changes
+
+### Cons
+1. **Single image only** - RSS spec ambiguous about multiple enclosures
+2. **No thumbnail metadata** - Readers must use full-size image
+3. **No alt text/caption** - Enclosure has no description attribute
+4. **Less prominent display** - Some readers treat enclosure as "download" not "display"
+
+### Complexity Score: 2/10
+
+---
+
+## Option 2: RSS + Media RSS Extension (Recommended)
+
+### Description
+Add both standard `<enclosure>` and Media RSS (`media:content`, `media:thumbnail`) elements. This provides maximum compatibility across modern feed readers while supporting multiple images and richer metadata.
+
+### Implementation Changes
+
+**File**: `/home/phil/Projects/starpunk/starpunk/feeds/rss.py`
+
+Add namespace to feed:
+```python
+# Register Media RSS namespace
+fg.register_extension('media', 'http://search.yahoo.com/mrss/')
+```
+
+Add media elements per item:
+```python
+if hasattr(note, 'media') and note.media:
+    for i, media_item in enumerate(note.media):
+        media_url = f"{site_url}/media/{media_item['path']}"
+        mime_type = media_item.get('mime_type', 'image/jpeg')
+        size = media_item.get('size', 0)
+        caption = media_item.get('caption', '')
+
+        # First image: use as enclosure AND thumbnail
+        if i == 0:
+            fe.enclosure(url=media_url, length=str(size), type=mime_type)
+            # Would need custom extension handling for media:thumbnail
+
+        # All images: add as media:content
+        # Note: feedgen doesn't support media:* natively
+        # May need to use custom XML generation or switch to streaming
+```
+
+**File**: `/home/phil/Projects/starpunk/starpunk/feeds/rss.py` (streaming - cleaner approach)
+
+```python
+# In XML header
+yield '<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/">\n'
+
+# In item generation
+if hasattr(note, 'media') and note.media:
+    for i, media_item in enumerate(note.media):
+        media_url = f"{site_url}/media/{media_item['path']}"
+        mime_type = media_item.get('mime_type', 'image/jpeg')
+        size = media_item.get('size', 0)
+        caption = _escape_xml(media_item.get('caption', ''))
+
+        # First image as enclosure (RSS 2.0 standard)
+        if i == 0:
+            yield f'      <enclosure url="{_escape_xml(media_url)}" length="{size}" type="{mime_type}"/>\n'
+            # Also as thumbnail for readers that prefer it
+            yield f'      <media:thumbnail url="{_escape_xml(media_url)}"/>\n'
+
+        # All images as media:content
+        yield f'      <media:content url="{_escape_xml(media_url)}" type="{mime_type}" fileSize="{size}" medium="image"'
+        if caption:
+            yield f'>\n'
+            yield f'        <media:description type="plain">{caption}</media:description>\n'
+            yield f'      </media:content>\n'
+        else:
+            yield f'/>\n'
+```
+
+### Pros
+1. **Maximum compatibility** - Works with all modern readers
+2. **Multiple images supported** - Media RSS handles arrays naturally
+3. **Rich metadata** - Captions, dimensions, alt text possible
+4. **Prominent display** - Readers using media:thumbnail show images well
+5. **Graceful degradation** - Falls back to enclosure for older readers
+
+### Cons
+1. **More complexity** - Multiple elements to generate
+2. **Namespace required** - Adds xmlns declaration
+3. **feedgen limitations** - May need streaming approach for full control
+4. **Spec sprawl** - Using RSS 2.0 + MRSS together
+
+### Complexity Score: 5/10
+
+---
+
+## Option 3: Full Standardization (All Formats)
+
+### Description
+Comprehensive update to all three feed formats ensuring consistent media handling with both structured elements AND HTML content, plus adding the `image` field to JSON Feed items.
+
+### Implementation Changes
+
+**RSS** (same as Option 2):
+- Add `<enclosure>` for first image
+- Add `<media:content>` for all images
+- Add `<media:thumbnail>` for first image
+- Keep HTML images in description
+
+**ATOM** (already mostly correct):
+- Current implementation is good
+- Consider adding `<media:thumbnail>` via MRSS namespace
+
+**JSON Feed**:
+```python
+# In _build_item_object()
+def _build_item_object(site_url: str, note: Note) -> Dict[str, Any]:
+    # ... existing code ...
+
+    # Add featured image (first image) at item level
+    if hasattr(note, 'media') and note.media:
+        first_media = note.media[0]
+        media_url = f"{site_url}/media/{first_media['path']}"
+        item["image"] = media_url  # Top-level image field
+
+        # Attachments array (existing code)
+        attachments = []
+        for media_item in note.media:
+            # ... existing attachment building ...
+        item["attachments"] = attachments
+```
+
+### Content Strategy Decision
+
+**Should HTML content include images?**
+
+Yes, always include images in HTML content (`description`, `content_html`) as well as in structured elements. Rationale:
+1. Some readers only render HTML, ignoring enclosures
+2. Ensures consistent display across all reader types
+3. ADR-057 and Q24 already mandate this approach
+4. IndieWeb convention supports redundant markup
+
+### Pros
+1. **Complete solution** - All formats fully supported
+2. **Maximum reader compatibility** - Covers all reader behaviors
+3. **Consistent experience** - Users see images regardless of reader
+4. **Future-proof** - Handles any new reader implementations
+
+### Cons
+1. **Most complex** - Changes to all three feed generators
+2. **Redundant data** - Images in multiple places (intentional)
+3. **Larger feed size** - More XML/JSON to transmit
+4. **Testing burden** - Must validate all three formats
+
+### Complexity Score: 7/10
+
+---
+
+## Recommendation
+
+**I recommend Option 2: RSS + Media RSS Extension** for the following reasons:
+
+### Rationale
+
+1. **Addresses the actual problem**: The user reported RSS as the problem format; ATOM and JSON Feed are working acceptably.
+
+2. **Best compatibility/complexity ratio**: Media RSS is widely supported by Feedly, Inoreader, and other major readers without excessive implementation burden.
+
+3. **Multiple image support**: Unlike Option 1, this handles the 2-4 image case that ADR-057 designed for.
+
+4. **Caption preservation**: Media RSS supports `<media:description>` which preserves alt text/captions.
+
+5. **Minimal JSON Feed changes**: JSON Feed only needs the `image` field addition (small change with good impact).
+
+### Implementation Priority
+
+1. **Phase 1**: Add `<enclosure>` to RSS (Option 1) - Immediate fix, 1 hour
+2. **Phase 2**: Add Media RSS namespace and elements - Enhanced fix, 2-3 hours
+3. **Phase 3**: Add `image` field to JSON Feed items - Polish, 30 minutes
+
+### Testing Validation
+
+After implementation, validate with:
+1. [W3C Feed Validator](https://validator.w3.org/feed/) - RSS/ATOM compliance
+2. [JSON Feed Validator](https://validator.jsonfeed.org/) - JSON Feed compliance
+3. Manual testing in: Feedly, NetNewsWire, Reeder, Inoreader, FreshRSS
+
+---
+
+## Decision Required
+
+The architect recommends **Option 2** but requests stakeholder input on:
+
+1. Is multiple image support in RSS essential, or is first-image-only acceptable?
+2. Are there specific feed readers that must be supported?
+3. What is the timeline for this fix?

+# Feed Media Enhancement Design: Option 2 (RSS + Media RSS Extension)
+
+## Overview
+
+This design document specifies the implementation of Option 2 for feed media support: adding Media RSS namespace elements to RSS feeds and the `image` field to JSON Feed items. This provides improved feed reader compatibility for notes with attached images.
+
+**Target Version**: v1.2.x
+**Estimated Effort**: 4-6 hours
+**Prerequisites**: Media attachment model implemented (ADR-057)
+
+## Current State
+
+### RSS Feed (`starpunk/feeds/rss.py`)
+- Embeds media as `<img>` tags within the `<description>` CDATA section
+- Uses feedgen library for RSS 2.0 generation
+- No `<enclosure>` elements
+- No Media RSS namespace
+
+### JSON Feed (`starpunk/feeds/json_feed.py`)
+- Includes media in `attachments` array (per JSON Feed 1.1 spec)
+- Includes media as `<img>` tags in `content_html`
+- No top-level `image` field for items
+
+### Note Model
+- Media accessed via `note.media` property (list of dicts)
+- Each media item has: `path`, `mime_type`, `size`, `caption` (optional)
+
+## Design Goals
+
+1. **Standards Compliance**: Follow Media RSS spec and JSON Feed 1.1 spec
+2. **Backward Compatibility**: Keep existing HTML embedding for universal reader support
+3. **Feed Reader Optimization**: Add structured metadata for enhanced display
+4. **Minimal Changes**: Modify only feed generation, no database changes
+
+## Files to Modify
+
+### 1. `starpunk/feeds/rss.py`
+
+**Changes Required**:
+
+#### A. Add Media RSS Namespace to Feed Generator
+
+Location: `generate_rss()` function and `generate_rss_streaming()` function
+
+```python
+# Add namespace registration before generating XML
+# For feedgen-based generation:
+fg.load_extension('media', rss=True)  # feedgen has built-in media extension
+
+# For streaming generation, add to opening RSS tag:
+'<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/">\n'
+```
+
+#### B. Add RSS `<enclosure>` Element (First Image Only)
+
+Per RSS 2.0 spec, only ONE enclosure per item is allowed. Use the first image.
+
+```python
+# In item generation, after setting description:
+if hasattr(note, 'media') and note.media:
+    first_media = note.media[0]
+    media_url = f"{site_url}/media/{first_media['path']}"
+    fe.enclosure(
+        url=media_url,
+        length=str(first_media.get('size', 0)),
+        type=first_media.get('mime_type', 'image/jpeg')
+    )
+```
+
+#### C. Add Media RSS Elements (All Images)
+
+For each image, add `<media:content>` and optional `<media:description>`:
+
+```python
+# Using feedgen's media extension:
+for media_item in note.media:
+    media_url = f"{site_url}/media/{media_item['path']}"
+
+    # Add media:content
+    fe.media.content({
+        'url': media_url,
+        'type': media_item.get('mime_type', 'image/jpeg'),
+        'medium': 'image',
+        'fileSize': str(media_item.get('size', 0))
+    })
+
+    # Add media:description if caption exists
+    if media_item.get('caption'):
+        fe.media.description(media_item['caption'], type='plain')
+
+# Add media:thumbnail for first image
+if note.media:
+    first_media = note.media[0]
+    fe.media.thumbnail({
+        'url': f"{site_url}/media/{first_media['path']}"
+    })
+```
+
+#### D. Expected XML Output Structure
+
+For an item with 2 images:
+
+```xml
+<item>
+  <title>My Note Title</title>
+  <link>https://example.com/note/my-slug</link>
+  <guid isPermaLink="true">https://example.com/note/my-slug</guid>
+  <pubDate>Mon, 09 Dec 2024 12:00:00 +0000</pubDate>
+
+  <!-- Standard RSS enclosure (first image only) -->
+  <enclosure url="https://example.com/media/2024/12/image1.jpg"
+             length="245760"
+             type="image/jpeg"/>
+
+  <!-- Media RSS elements (all images) -->
+  <media:content url="https://example.com/media/2024/12/image1.jpg"
+                 type="image/jpeg"
+                 medium="image"
+                 fileSize="245760"/>
+  <media:content url="https://example.com/media/2024/12/image2.jpg"
+                 type="image/jpeg"
+                 medium="image"
+                 fileSize="198432"/>
+
+  <!-- Thumbnail (first image) -->
+  <media:thumbnail url="https://example.com/media/2024/12/image1.jpg"/>
+
+  <!-- Caption if present -->
+  <media:description type="plain">Photo from today's hike</media:description>
+
+  <!-- Description with embedded HTML (for legacy readers) -->
+  <description><![CDATA[
+    <div class="media">
+      <img src="https://example.com/media/2024/12/image1.jpg" alt="Photo from today's hike" />
+      <img src="https://example.com/media/2024/12/image2.jpg" alt="" />
+    </div>
+    <p>Note content here...</p>
+  ]]></description>
+</item>
+```
+
+### 2. `starpunk/feeds/json_feed.py`
+
+**Changes Required**:
+
+#### A. Add `image` Field to Item Objects
+
+Per JSON Feed 1.1 spec, `image` is "the URL of the main image for the item."
+
+Location: `_build_item_object()` function
+
+```python
+def _build_item_object(site_url: str, note: Note) -> Dict[str, Any]:
+    # ... existing code ...
+
+    # Add image field (URL of first/main image)
+    # Per JSON Feed 1.1: "the URL of the main image for the item"
+    if hasattr(note, 'media') and note.media:
+        first_media = note.media[0]
+        item["image"] = f"{site_url}/media/{first_media['path']}"
+
+    # ... rest of existing code (content_html, attachments, etc.) ...
+```
+
+#### B. Expected JSON Output Structure
+
+```json
+{
+  "id": "https://example.com/note/my-slug",
+  "url": "https://example.com/note/my-slug",
+  "title": "My Note Title",
+  "date_published": "2024-12-09T12:00:00Z",
+
+  "image": "https://example.com/media/2024/12/image1.jpg",
+
+  "content_html": "<div class=\"media\"><img src=\"https://example.com/media/2024/12/image1.jpg\" alt=\"Photo from today's hike\" /><img src=\"https://example.com/media/2024/12/image2.jpg\" alt=\"\" /></div><p>Note content here...</p>",
+
+  "attachments": [
+    {
+      "url": "https://example.com/media/2024/12/image1.jpg",
+      "mime_type": "image/jpeg",
+      "title": "Photo from today's hike",
+      "size_in_bytes": 245760
+    },
+    {
+      "url": "https://example.com/media/2024/12/image2.jpg",
+      "mime_type": "image/jpeg",
+      "size_in_bytes": 198432
+    }
+  ],
+
+  "_starpunk": {
+    "permalink_path": "/note/my-slug",
+    "word_count": 42
+  }
+}
+```
+
+## Implementation Details
+
+### RSS Implementation: feedgen vs Manual Streaming
+
+**For `generate_rss()` (feedgen-based)**:
+
+The feedgen library has a media extension. Check if it's available:
+
+```python
+# Test if feedgen supports media extension
+from feedgen.ext.media import MediaExtension
+
+# If supported, use:
+fg.register_extension('media', MediaExtension, rss=True)
+```
+
+If feedgen's media extension is insufficient, consider manual XML injection after feedgen generates the base XML.
+
+**For `generate_rss_streaming()` (manual XML)**:
+
+Modify the streaming generator to include media elements. This requires:
+
+1. Update the opening RSS tag to include media namespace
+2. Add `<enclosure>` element after `<pubDate>`
+3. Add `<media:content>` elements for each image
+4. Add `<media:thumbnail>` for first image
+5. Add `<media:description>` if caption exists
+
+### JSON Feed Implementation
+
+Straightforward addition in `_build_item_object()`:
+
+```python
+# Add image field if media exists
+if hasattr(note, 'media') and note.media:
+    first_media = note.media[0]
+    item["image"] = f"{site_url}/media/{first_media['path']}"
+```
+
+## Testing Requirements
+
+### Unit Tests to Add/Modify
+
+**File**: `tests/test_feeds_rss.py` (create or extend)
+
+```python
+def test_rss_enclosure_for_note_with_media():
+    """RSS item should include enclosure element for first image."""
+    # Create note with media
+    # Generate RSS
+    # Parse XML, verify <enclosure> present with correct attributes
+
+def test_rss_media_content_for_all_images():
+    """RSS item should include media:content for each image."""
+    # Create note with 2 images
+    # Generate RSS
+    # Parse XML, verify 2 <media:content> elements
+
+def test_rss_media_thumbnail_for_first_image():
+    """RSS item should include media:thumbnail for first image."""
+    # Create note with media
+    # Generate RSS
+    # Parse XML, verify <media:thumbnail> present
+
+def test_rss_media_description_for_caption():
+    """RSS item should include media:description if caption exists."""
+    # Create note with captioned image
+    # Generate RSS
+    # Parse XML, verify <media:description> present
+
+def test_rss_no_media_elements_without_attachments():
+    """RSS item without media should have no media elements."""
+    # Create note without media
+    # Generate RSS
+    # Parse XML, verify no enclosure or media:* elements
+
+def test_rss_namespace_declaration():
+    """RSS feed should declare media namespace."""
+    # Generate any RSS feed
+    # Verify xmlns:media attribute in root element
+```
+
+**File**: `tests/test_feeds_json.py` (create or extend)
+
+```python
+def test_json_feed_image_field_for_note_with_media():
+    """JSON Feed item should include image field for first image."""
+    # Create note with media
+    # Generate JSON feed
+    # Parse JSON, verify "image" field present with correct URL
+
+def test_json_feed_no_image_field_without_media():
+    """JSON Feed item without media should not have image field."""

+    """JSON Feed image field should use first media item URL."""
+    # Create note with 3 images
+    # Generate JSON feed
+    # Verify "image" URL matches first image path
+```
+
+### Feed Validation Tests
+
+**Manual Validation** (document in test plan):
+
+1. **W3C Feed Validator**: https://validator.w3.org/feed/
+   - Submit generated RSS feed
+   - Verify no errors for media:* elements
+   - Note: Validator may warn about unknown extensions (acceptable)
+
+2. **Feed Reader Testing**:
+   - Feedly: Verify images display in article preview
+   - NetNewsWire: Check media thumbnail in list view
+   - Feedbin: Test image extraction
+   - RSS.app: Verify enclosure handling
+
+3. **JSON Feed Validator**: Use online JSON Feed validator
+   - Verify `image` field accepted
+   - Verify `attachments` array valid
+
+### Integration Tests
+
+```python
+def test_rss_route_with_media_notes(client, app):
+    """GET /feed.xml with media notes returns valid RSS with media elements."""
+    # Create test notes with media
+    # Request /feed.xml
+    # Verify response contains media namespace and elements
+
+def test_json_route_with_media_notes(client, app):
+    """GET /feed.json with media notes returns JSON with image fields."""
+    # Create test notes with media
+    # Request /feed.json
+    # Verify response contains image fields
+```
+

+
+### Media RSS Specification
+- **URL**: https://www.rssboard.org/media-rss
+- **Key Elements Used**:
+  - `media:content` - Primary media reference
+  - `media:thumbnail` - Preview image
+  - `media:description` - Caption text
+
+### JSON Feed 1.1 Specification
+- **URL**: https://jsonfeed.org/version/1.1/
+- **Key Fields Used**:
+  - `image` (item level) - "the URL of the main image for the item"

+# Media Display Fixes - Architectural Design
+
+## Status
+Active
+
+## Problem Statement
+Three issues with current media display implementation:
+1. **Images too large** - No CSS constraints on image dimensions
+2. **Captions visible** - Currently showing figcaption, should use alt text only
+3. **Images missing on homepage** - Media not fetched or displayed in index.html
+
+## Root Cause Analysis
+
+### Issue 1: Images Too Large
+The current CSS (`/static/css/style.css`) has NO styles for:
+- `.note-media` container
+- `.media-item` figure elements
+- `.u-photo` images
+- Responsive image constraints
+
+Images display at their native dimensions, which can break layouts.
+
+### Issue 2: Captions Visible
+Template (`note.html` lines 25-27) explicitly renders figcaption:
+```html
+{% if item.caption %}
+<figcaption>{{ item.caption }}</figcaption>
+{% endif %}
+```
+This violates the social media pattern where captions are for accessibility (alt text) only.
+
+### Issue 3: Missing Homepage Media
+The index route (`public.py` line 231) doesn't fetch media:
+```python
+notes = list_notes(published_only=True, limit=20)
+```
+Compare to the note route (lines 263-267) which DOES fetch media.
+
+## Architectural Solution
+
+### Design Principles
+1. **Consistency**: Same media display logic on all pages
+2. **Responsive**: Images adapt to viewport and container
+3. **Accessible**: Alt text for screen readers, no visible captions
+4. **Performance**: Lazy loading for below-fold images
+5. **Standards**: Proper Microformats2 markup maintained
+
+### Component Architecture
+
+#### 1. CSS Media Display System
+Create responsive, constrained image display with grid layouts:
+
+```css
+/* Media container styles */
+.note-media {
+  margin-bottom: var(--spacing-md);
+  width: 100%;
+}
+
+/* Single image - full width */
+.note-media:has(.media-item:only-child) {
+  max-width: 100%;
+}
+
+.note-media:has(.media-item:only-child) .media-item {
+  width: 100%;
+}
+
+/* Two images - side by side */
+.note-media:has(.media-item:nth-child(2):last-child) {
+  display: grid;
+  grid-template-columns: repeat(2, 1fr);
+  gap: var(--spacing-sm);
+}
+
+/* Three or four images - grid */
+.note-media:has(.media-item:nth-child(3)),
+.note-media:has(.media-item:nth-child(4)) {
+  display: grid;
+  grid-template-columns: repeat(2, 1fr);
+  gap: var(--spacing-sm);
+}
+
+/* Media item wrapper */
+.media-item {
+  margin: 0;
+  padding: 0;
+  background: var(--color-bg-alt);
+  border-radius: var(--border-radius);
+  overflow: hidden;
+  aspect-ratio: 1 / 1; /* Instagram-style square crop */
+  display: flex;
+  align-items: center;
+  justify-content: center;
+}
+
+/* Image constraints */
+.media-item img,
+.u-photo {
+  width: 100%;
+  height: 100%;
+  object-fit: cover; /* Crop to fill container */
+  display: block;
+}
+
+/* For single images, allow natural aspect ratio */
+.note-media:has(.media-item:only-child) .media-item {
+  aspect-ratio: auto;
+  max-height: 500px; /* Prevent extremely tall images */
+}
+
+.note-media:has(.media-item:only-child) .media-item img {
+  object-fit: contain; /* Show full image for singles */
+  width: 100%;
+  height: auto;
+  max-height: 500px;
+}
+
+/* Remove figcaption from display */
+.media-item figcaption {
+  display: none; /* Captions are for alt text only */
+}
+
+/* Mobile responsive adjustments */
+@media (max-width: 767px) {
+  /* Stack images vertically on small screens */
+  .note-media:has(.media-item:nth-child(2):last-child) {
+    grid-template-columns: 1fr;
+  }
+
+  .media-item {
+    aspect-ratio: 16 / 9; /* Wider aspect on mobile */
+  }
+}
+```
+
+#### 2. Template Refactoring
+
+Create a reusable macro for media display to ensure consistency:
+
+**New template partial: `templates/partials/media.html`**
+```jinja2
+{# Reusable media display macro #}
+{% macro display_media(media_items) %}
+  {% if media_items %}
+  <div class="note-media">
+    {% for item in media_items %}
+    <figure class="media-item">
+      <img src="{{ url_for('public.media_file', path=item.path) }}"
+           alt="{{ item.caption or 'Image' }}"
+           class="u-photo"
+           loading="lazy">
+      {# No figcaption - caption is for alt text only #}
+    </figure>
+    {% endfor %}
+  </div>
+  {% endif %}
+{% endmacro %}
+```
+
+**Updated `note.html`** (lines 16-31):
+```jinja2
+{# Import media macro #}
+{% from "partials/media.html" import display_media %}
+
+{# Media display at TOP (v1.2.0 Phase 3, per ADR-057) #}
+{{ display_media(note.media) }}
+```
+
+**Updated `index.html`** (after line 26, before e-content):
+```jinja2
+{# Import media macro at top of file #}
+{% from "partials/media.html" import display_media %}
+
+{# In the note loop, after the title check #}
+      {% if has_explicit_title %}
+      <h3 class="p-name">{{ note.title }}</h3>
+      {% endif %}
+
+      {# Media preview (if available) #}
+      {{ display_media(note.media) }}
+
+      {# e-content: note content (preview) #}
+      <div class="e-content">
+```
+
+#### 3. Route Handler Updates
+
+Update the index route to fetch media for each note:
+
+**`starpunk/routes/public.py`** (lines 219-233):
+```python
+@bp.route("/")
+def index():
+    """
+    Homepage displaying recent published notes with media
+
+    Returns:
+        Rendered homepage template with note list including media
+
+    Template: templates/index.html
+    Microformats: h-feed containing h-entry items with u-photo
+    """
+    from starpunk.media import get_note_media
+
+    # Get recent published notes (limit 20)
+    notes = list_notes(published_only=True, limit=20)
+
+    # Attach media to each note for display
+    for note in notes:
+        media = get_note_media(note.id)
+        # Use object.__setattr__ since Note is frozen dataclass
+        object.__setattr__(note, 'media', media)
+
+    return render_template("index.html", notes=notes)
+```
+
+### Implementation Guidelines
+
+#### Phase 1: CSS Foundation
+1. Add media display styles to `/static/css/style.css`
+2. Test with 1, 2, 3, and 4 image layouts
+3. Verify responsive behavior on mobile/tablet/desktop
+4. Ensure images don't overflow containers
+
+#### Phase 2: Template Refactoring
+1. Create `templates/partials/` directory if not exists
+2. Create `media.html` with display macro
+3. Update `note.html` to use macro
+4. Update `index.html` to import and use macro
+5. Remove figcaption rendering completely
+
+#### Phase 3: Route Updates
+1. Import `get_note_media` in index route
+2. Fetch media for each note in loop
+3. Attach media using `object.__setattr__`
+4. Verify media passes to template
+
+### Testing Checklist
+
+#### Visual Tests
+- [ ] Single image displays at reasonable size
+- [ ] Two images display side-by-side
+- [ ] Three images display in 2x2 grid (one empty)
+- [ ] Four images display in 2x2 grid
+- [ ] Images maintain aspect ratio appropriately
+- [ ] No layout overflow on any screen size
+- [ ] Captions not visible (alt text only)
+
+#### Functional Tests
+- [ ] Homepage shows media for notes
+- [ ] Individual note page shows media
+- [ ] Media lazy loads below fold
+- [ ] Alt text present for accessibility
+- [ ] Microformats2 u-photo preserved
+
+#### Performance Tests
+- [ ] Page load time acceptable with media
+- [ ] Images don't block initial render
+- [ ] Lazy loading works correctly
+
+### Security Considerations
+- Media paths already sanitized in media_file route
+- Alt text must be HTML-escaped in templates
+- No user-controlled CSS injection points
+
+### Accessibility Requirements
+- Alt text MUST be present (fallback to "Image")
+- Images must not convey information not in text
+- Focus indicators for keyboard navigation
+- Proper semantic HTML (figure elements)
+
+### Future Enhancements (Not for V1)
+- Image optimization/resizing on upload
+- WebP format support with fallbacks
+- Lightbox for full-size viewing
+- Video/audio media support
+- CDN integration for media serving
+
+## Decision Rationale
+
+### Why Grid Layout?
+- Native CSS, no JavaScript required
+- Excellent responsive support
+- Handles variable image counts elegantly
+- Familiar social media pattern
+
+### Why Hide Captions?
+- Follows Twitter/Mastodon pattern
+- Captions are for accessibility (alt text)
+- Cleaner visual presentation
+- Text content provides context
+
+### Why Lazy Loading?
+- Improves initial page load
+- Reduces bandwidth for visitors
+- Native browser support
+- Progressive enhancement
+
+### Why Aspect Ratio Control?
+- Prevents layout shift during load
+- Creates consistent grid appearance
+- Matches social media expectations
+- Improves visual harmony
+
+## Implementation Priority
+1. **Critical**: Fix homepage media display (functionality gap)
+2. **High**: Add CSS constraints (UX/visual issue)
+3. **Medium**: Hide captions (visual polish)
+
+All three fixes should be implemented together for consistency.

+# Caption Display Update - Alt Text Only (v1.1.2)
+
+## Status
+**Superseded by media-display-fixes.md**
+
+This document contains an earlier approach to caption handling. The authoritative specification is now in `media-display-fixes.md` which provides a complete solution for media display including caption handling, CSS constraints, and homepage media.
+
+## Context
+
+User has clarified that media captions should be used as alt text only, not displayed as visible `<figcaption>` elements in the note body.
+
+## Decision
+
+Remove all visible caption display from templates while maintaining caption data for accessibility (alt text) purposes.
+
+## Required Changes
+
+### 1. CSS Updates
+
+**File:** `/home/phil/Projects/starpunk/static/css/style.css`
+
+**Remove:** Lines related to figcaption styling (line 17 in the media CSS section)
+
+```css
+/* REMOVE THIS LINE */
+.note-media figcaption, .e-content figcaption { margin-top: var(--spacing-sm); font-size: 0.875rem; color: var(--color-text-light); font-style: italic; }
+```
+
+The remaining CSS should be:
+
+```css
+/* Media Display Styles (v1.2.0) - Updated for alt-text only captions */
+.note-media { margin-bottom: var(--spacing-md); }
+.note-media img, .e-content img, .u-photo { max-width: 100%; height: auto; display: block; border-radius: var(--border-radius); }
+
+/* Multiple media items grid */
+.note-media { display: flex; flex-wrap: wrap; gap: var(--spacing-md); }
+.note-media .media-item { flex: 1 1 100%; }
+
+/* Desktop: side-by-side for multiple images */
+@media (min-width: 768px) {
+  .note-media .media-item:only-child { flex: 1 1 100%; }
+  .note-media .media-item:not(:only-child) { flex: 1 1 calc(50% - var(--spacing-sm)); }
+}
+```
+
+### 2. Template Updates
+
+#### File: `/home/phil/Projects/starpunk/templates/note.html`
+
+**Change:** Lines 17-29 - Simplify media display structure
+
+**From:**
+```html
+{% if note.media %}
+<div class="note-media">
+  {% for item in note.media %}
+  <figure class="media-item">
+    <img src="{{ url_for('public.media_file', path=item.path) }}"
+         alt="{{ item.caption or 'Image' }}"
+         class="u-photo"
+         width="{{ item.width }}"
+         height="{{ item.height }}">
+    {% if item.caption %}
+    <figcaption>{{ item.caption }}</figcaption>
+    {% endif %}
+  </figure>
+  {% endfor %}
+</div>
+{% endif %}
+```
+
+**To:**
+```html
+{% if note.media %}
+<div class="note-media">
+  {% for item in note.media %}
+  <div class="media-item">
+    <img src="{{ url_for('public.media_file', path=item.path) }}"
+         alt="{{ item.caption or 'Image' }}"
+         class="u-photo"
+         width="{{ item.width }}"
+         height="{{ item.height }}">
+  </div>
+  {% endfor %}
+</div>
+{% endif %}
+```
+
+**Changes:**
+- Replace `<figure>` with `<div>` (simpler, no semantic figure/caption relationship)
+- Remove the `{% if item.caption %}` block and `<figcaption>` element entirely
+- Keep caption in `alt` attribute for accessibility
+
+#### File: `/home/phil/Projects/starpunk/templates/index.html`
+
+**Status:** No changes needed
+- Index template doesn't display media items in the preview
+- Only shows truncated content
+
+### 3. Feed Generators
+
+**Status:** No changes needed
+
+The feed generators already handle captions correctly:
+- RSS, ATOM, and JSON Feed all use captions as alt text in `<img>` tags
+- JSON Feed also includes captions in attachment metadata (correct behavior)
+
+**Current implementation (correct):**
+```python
+# In all feed generators
+caption = media_item.get('caption', '')
+content_html += f'<img src="{media_url}" alt="{caption}" />'
+```
+
+## Rationale
+
+1. **Simplicity**: Removing visible captions reduces visual clutter
+2. **Accessibility**: Alt text provides necessary context for screen readers
+3. **User Intent**: Captions are metadata, not content to be displayed
+4. **Clean Design**: Images speak for themselves without redundant text
+
+## Implementation Checklist
+
+- [ ] Update CSS to remove figcaption styles
+- [ ] Update note.html template to remove figcaption elements
+- [ ] Test with images that have captions
+- [ ] Test with images without captions
+- [ ] Verify alt text is properly set
+- [ ] Test responsive layout still works
+- [ ] Verify feed output unchanged
+
+## Testing Requirements
+
+1. **Visual Testing:**
+   - Confirm no caption text appears below images
+   - Verify image layout unchanged
+   - Test responsive behavior on mobile/desktop
+
+2. **Accessibility Testing:**
+   - Inspect HTML to confirm alt attributes are set
+   - Test with screen reader to verify alt text is announced
+
+3. **Feed Testing:**
+   - Verify RSS/ATOM/JSON feeds still include alt text
+   - Confirm JSON Feed attachments retain title field
+
+## Standards Compliance
+
+- **HTML**: Valid use of img alt attribute
+- **Accessibility**: WCAG 2.1 Level A compliance for images
+- **IndieWeb**: Maintains u-photo microformat class
+- **Progressive Enhancement**: Images functional without CSS

+
+2. **Content Support**
+   - Text content (escaped)
+   - HTML content (escaped or CDATA)
+   - XHTML content (inline XML)
+   - Base64 for binary (future)
+
+3. **Metadata Richness**
+   - Author information
+   - Category/tag support
+   - Updated vs published dates
+   - Link relationships
+
+4. **Streaming Generation**

+```
+
+### Date Formatting
+
+ATOM uses RFC 3339 date format, which is a profile of ISO 8601.
+
+```python
+def _format_atom_date(self, dt: datetime) -> str:
+    """Format datetime to RFC 3339 for ATOM
+
+    Format: 2024-11-25T12:00:00Z or 2024-11-25T12:00:00-05:00
+
+    Args:
+        dt: Datetime object (naive assumed UTC)
+
+    Returns:
+        RFC 3339 formatted string
+    """
+    # Ensure timezone aware
+    if dt.tzinfo is None:
+        dt = dt.replace(tzinfo=timezone.utc)
+
+    # Format to RFC 3339
+    # Use 'Z' for UTC, otherwise offset
+    if dt.tzinfo == timezone.utc:
+        return dt.strftime('%Y-%m-%dT%H:%M:%SZ')
+    else:
+        return dt.strftime('%Y-%m-%dT%H:%M:%S%z')
+```
+
+### XML Escaping
+
+```python
+def _escape_xml(self, text: str) -> str:
+    """Escape special XML characters
+
+    Escapes: & < > " '
+
+    Args:
+        text: Text to escape
+
+    Returns:
+        XML-safe escaped text
+    """
+    if not text:
+        return ''
+
+    # Order matters: & must be first
+    text = text.replace('&', '&amp;')
+    text = text.replace('<', '&lt;')
+    text = text.replace('>', '&gt;')
+    text = text.replace('"', '&quot;')
+    text = text.replace("'", '&apos;')
+
+    return text
+```
+
+## Content Type Handling
+
+### Text Content
+
+Plain text, must be escaped:
+
+```xml
+<content type="text">This is plain text with &lt;escaped&gt; characters</content>
+```
+
+### HTML Content
+
+HTML as escaped text:
+
+```xml
+<content type="html">&lt;p&gt;This is &lt;strong&gt;HTML&lt;/strong&gt; content&lt;/p&gt;</content>
+```
+
+### XHTML Content (Future)
+
+Well-formed XML inline:
+
+```xml
+<content type="xhtml">
+  <div xmlns="http://www.w3.org/1999/xhtml">
+    <p>This is <strong>XHTML</strong> content</p>
+  </div>
+</content>
+```
+
+## Complete ATOM Feed Example
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<feed xmlns="http://www.w3.org/2005/Atom">
+  <id>https://example.com/</id>
+  <title>StarPunk Notes</title>
+  <updated>2024-11-25T12:00:00Z</updated>
+  <link rel="alternate" type="text/html" href="https://example.com"/>
+  <link rel="self" type="application/atom+xml" href="https://example.com/feed.atom"/>
+  <subtitle>Personal notes and thoughts</subtitle>
+  <generator version="1.1.2" uri="https://starpunk.app">StarPunk</generator>
+
+  <entry>
+    <id>https://example.com/notes/2024/11/25/first-note</id>
+    <title>My First Note</title>
+    <updated>2024-11-25T10:30:00Z</updated>

+</feed>
+```
+
+## Validation
+
+### W3C Feed Validator Compliance
+
+The generated ATOM feed must pass validation at:
+- https://validator.w3.org/feed/
+
+### Common Validation Issues
+
+1. **Missing Required Elements**
+   - Ensure id, title, updated are present
+   - Each entry must have these elements too
+
+2. **Invalid Dates**
+   - Must be RFC 3339 format
+   - Include timezone information
+
+3. **Improper Escaping**
+   - All XML entities must be escaped
+   - No raw HTML in text content
+
+4. **Namespace Issues**
+   - Correct namespace declaration
+   - No prefixed elements without namespace

+## Security Considerations
+
+1. **XML Injection Prevention**
+   - All user content must be escaped
+   - No raw XML from user input
+   - Validate all URLs
+
+2. **Content Security**
+   - HTML content properly escaped
+   - No script tags allowed
+   - Sanitize all metadata
+
+3. **Resource Limits**
+   - Maximum feed size limits
+   - Timeout on generation
+   - Rate limiting on endpoint
+

+# Critical: RSS Feed Ordering Regression Fix
+
+## Status: MUST FIX IN PHASE 2
+
+**Date Identified**: 2025-11-26
+**Severity**: CRITICAL - Production Bug
+**Impact**: All RSS feed consumers see oldest content first
+
+## The Bug
+
+### Current Behavior (INCORRECT)
+RSS feeds are showing entries in ascending chronological order (oldest first) instead of the expected descending order (newest first).
+
+### Location
+- File: `/home/phil/Projects/starpunk/starpunk/feed.py`
+- Line 100: `for note in reversed(notes[:limit]):`
+- Line 198: `for note in reversed(notes[:limit]):`
+
+### Root Cause
+The code incorrectly applies `reversed()` to the notes list. The database already returns notes in DESC order (newest first), which is the correct order for feeds. The `reversed()` call flips this to ascending order (oldest first).
+
+The misleading comment "Notes from database are DESC but feedgen reverses them, so we reverse back" is incorrect - feedgen does NOT reverse the order.
+
+## Expected Behavior
+
+**ALL feed formats MUST show newest entries first:**
+
+| Format | Standard | Expected Order |
+|--------|----------|----------------|
+| RSS 2.0 | Industry standard | Newest first |
+| ATOM 1.0 | RFC 4287 recommendation | Newest first |
+| JSON Feed 1.1 | Specification convention | Newest first |
+
+This is not optional - it's the universally expected behavior for all syndication formats.
+
+## Fix Implementation
+
+### Phase 2.0 - Fix RSS Feed Ordering (0.5 hours)
+
+#### Step 1: Remove Incorrect Reversals
+```python
+# Line 100 - BEFORE
+for note in reversed(notes[:limit]):
+
+# Line 100 - AFTER
+for note in notes[:limit]:
+
+# Line 198 - BEFORE
+for note in reversed(notes[:limit]):
+
+# Line 198 - AFTER
+for note in notes[:limit]:
+```
+
+#### Step 2: Update/Remove Misleading Comments
+Remove or correct the comment about feedgen reversing order.
+
+#### Step 3: Add Comprehensive Tests
+```python
+def test_rss_feed_newest_first():
+    """Test RSS feed shows newest entries first"""
+    old_note = create_note(title="Old", created_at=yesterday)
+    new_note = create_note(title="New", created_at=today)
+
+    feed = generate_rss_feed([new_note, old_note])
+    items = parse_feed_items(feed)
+
+    assert items[0].title == "New"
+    assert items[1].title == "Old"
+```
+
+## Prevention Strategy
+
+### 1. Document Expected Behavior
+All feed generator classes now include explicit documentation:
+```python
+def generate(self, notes: List[Note], limit: int = 50):
+    """Generate feed
+
+    IMPORTANT: Notes are expected to be in DESC order (newest first)
+    from the database. This order MUST be preserved in the feed.
+    """
+```
+
+### 2. Implement Order Tests for All Formats
+Every feed format specification now includes mandatory order testing:
+- RSS: `test_rss_feed_newest_first()`
+- ATOM: `test_atom_feed_newest_first()`
+- JSON: `test_json_feed_newest_first()`
+
+### 3. Add to Developer Q&A
+Created CQ9 (Critical Question 9) in the developer Q&A document explicitly stating that newest-first is required for all formats.
+
+## Updated Documents
+
+The following documents have been updated to reflect this critical fix:
+
+1. **`docs/design/v1.1.2/implementation-guide.md`**
+   - Added Phase 2.0 for RSS feed ordering fix
+   - Added feed ordering tests to Phase 2 test requirements
+   - Marked as CRITICAL priority
+
+2. **`docs/design/v1.1.2/atom-feed-specification.md`**
+   - Added order preservation documentation to generator
+   - Added `test_feed_order_newest_first()` test
+   - Added "DO NOT reverse" warning comments
+
+3. **`docs/design/v1.1.2/json-feed-specification.md`**
+   - Added order preservation documentation to generator
+   - Added `test_feed_order_newest_first()` test
+   - Added "DO NOT reverse" warning comments
+
+4. **`docs/design/v1.1.2/developer-qa.md`**
+   - Added CQ9: Feed Entry Ordering
+   - Documented industry standards for each format
+   - Included testing requirements
+
+## Verification Steps
+
+After implementing the fix:
+
+1. Generate RSS feed with multiple notes
+2. Verify first entry has the most recent date
+3. Test with popular feed readers:
+   - Feedly
+   - Inoreader
+   - NewsBlur
+   - The Old Reader
+
+4. Run all feed ordering tests
+5. Validate feeds with online validators
+
+## Timeline
+
+This fix MUST be implemented at the beginning of Phase 2, before any work on ATOM or JSON Feed formats. The corrected RSS implementation will serve as the reference for the new formats.
+
+## Notes
+
+This regression likely occurred due to a misunderstanding about how feedgen handles entry order. The lesson learned is to always verify assumptions about third-party libraries and to implement comprehensive tests for critical user-facing behavior like feed ordering.

+# Developer Q&A for StarPunk v1.1.2 "Syndicate"
+
+**Developer**: StarPunk Fullstack Developer
+**Date**: 2025-11-25
+**Purpose**: Pre-implementation questions for architect review
+
+## Document Overview
+
+This document contains questions identified during the design review of v1.1.2 "Syndicate" specifications. Questions are organized by priority to help the architect focus on blocking issues first.
+
+---
+
+## Critical Questions (Must be answered before implementation)
+
+These questions address blocking issues, unclear requirements, integration points, and major technical decisions that prevent implementation from starting.
+
+### CQ1: Database Instrumentation Integration
+
+**Question**: How should the MonitoredConnection wrapper integrate with the existing database pool implementation?
+
+**Context**:
+- The spec shows a `MonitoredConnection` class that wraps SQLite connections (metrics-instrumentation-spec.md, lines 60-114)
+- We currently have a connection pool in `starpunk/database/pool.py`
+- The spec doesn't clarify whether we:
+  1. Wrap the pool's `get_connection()` method to return wrapped connections
+  2. Replace the pool's connection creation logic
+  3. Modify the pool class itself to include monitoring
+
+**Current Understanding**:
+- I see we have `starpunk/database/pool.py` which manages connections
+- The spec suggests wrapping individual connection's `execute()` method
+- But unclear how this fits with the pool's lifecycle management
+
+**Impact**:
+- Affects database module architecture
+- Determines whether pool needs refactoring
+- May affect existing database queries throughout codebase
+
+**Proposed Approach**:
+Wrap connections at pool level by modifying `get_connection()` to return `MonitoredConnection(real_conn, metrics_collector)`. Is this correct?
+
+---
+
+### CQ2: Metrics Collector Lifecycle and Initialization
+
+**Question**: When and where should the global MetricsCollector instance be initialized, and how should it be passed to all monitoring components?
+
+**Context**:
+- Multiple components need access to the same collector (metrics-instrumentation-spec.md):
+  - MonitoredConnection (database)
+  - HTTPMetricsMiddleware (Flask)
+  - MemoryMonitor (background thread)
+  - SyndicationMetrics (business metrics)
+- No specification for initialization order or dependency injection strategy
+- Flask app initialization happens in `app.py` but monitoring setup is unclear
+
+**Current Understanding**:
+- Need a single collector instance shared across all components
+- Should probably initialize during Flask app setup
+- But unclear if it should be:
+  - App config attribute: `app.metrics_collector`
+  - Global module variable: `from starpunk.monitoring import metrics_collector`
+  - Passed via dependency injection to all modules
+
+**Impact**:
+- Affects application initialization sequence
+- Determines module coupling and testability
+- Affects how metrics are accessed in route handlers
+
+**Proposed Approach**:
+Create collector during Flask app factory, store as `app.metrics_collector`, and pass to monitoring components during setup. Is this the intended pattern?
+
+---
+
+### CQ3: Content Negotiation vs. Explicit Format Endpoints
+
+**Question**: Should we support BOTH explicit format endpoints (`/feed.rss`, `/feed.atom`, `/feed.json`) AND content negotiation on `/feed`, or only content negotiation?
+
+**Context**:
+- ADR-054 section 3 chooses "Content Negotiation" as the preferred approach (lines 155-162)
+- But the architecture diagram (v1.1.2-syndicate-architecture.md) shows "HTTP Request Layer" with "Content Negotiator"
+- Implementation guide (lines 586-592) shows both explicit URLs AND a `/feed` endpoint
+- feed-enhancements-spec.md (line 342) shows a `/feed.<format>` route pattern
+
+**Current Understanding**:
+- ADR-054 prefers content negotiation for standards compliance
+- But examples show explicit `.atom`, `.json` extensions working
+- Unclear if we should implement both for compatibility
+
+**Impact**:
+- Affects route definition strategy
+- Changes URL structure for feeds
+- Determines whether to maintain backward compatibility URLs
+
+**Proposed Approach**:
+Implement both: `/feed.xml` (existing), `/feed.atom`, `/feed.json` for explicit access, PLUS `/feed` with content negotiation as the primary endpoint. Keep `/feed.xml` working for backward compatibility. Is this correct?
+
+---
+
+### CQ4: Cache Checksum Calculation Strategy
+
+**Question**: Should the cache checksum include ALL notes or only the notes that will appear in the feed (respecting the limit)?
+
+**Context**:
+- feed-enhancements-spec.md shows checksum based on "latest note timestamp and count" (lines 317-325)
+- But feeds are limited (default 50 items)
+- If someone publishes note #51, does that invalidate cache for format with limit=50?
+
+**Current Understanding**:
+- Checksum based on: latest timestamp + total count + config
+- But this means cache invalidates even if new note wouldn't appear in limited feed
+- Could be wasteful regeneration
+
+**Impact**:
+- Affects cache hit rates
+- Determines when feeds actually need regeneration
+- May impact performance goals (>80% cache hit rate)
+
+**Proposed Approach**:
+Use checksum based on the latest timestamp of notes that WOULD appear in feed (i.e., first N notes), not all notes. Is this the intent, or should we invalidate for ANY new note?
+
+---
+
+### CQ5: Memory Monitor Thread Lifecycle
+
+**Question**: How should the MemoryMonitor thread be started, stopped, and managed during application lifecycle (startup, shutdown, restarts)?
+
+**Context**:
+- metrics-instrumentation-spec.md shows `MemoryMonitor(Thread)` with daemon flag (line 206)
+- Background thread needs to be started during app initialization
+- But Flask app lifecycle unclear:
+  - When to start thread?
+  - How to handle graceful shutdown?
+  - What about development reloader (Flask debug mode)?
+
+**Current Understanding**:
+- Daemon thread will auto-terminate when main process exits
+- But no specification for:
+  - Starting thread after Flask app created
+  - Preventing duplicate threads in debug mode
+  - Cleanup on shutdown
+
+**Impact**:
+- Affects application stability
+- Determines proper shutdown behavior
+- May cause issues in development with auto-reload
+
+**Proposed Approach**:
+Start thread after Flask app initialized, set daemon=True, store reference in `app.memory_monitor`, implement `app.teardown_appcontext` cleanup. Should we prevent thread start in test mode?
+
+---
+
+### CQ6: Feed Generator Streaming Implementation
+
+**Question**: For ATOM and JSON Feed generators, should we implement BOTH a complete generation method (`generate()`) and streaming method (`generate_streaming()`), or only streaming?
+
+**Context**:
+- ADR-054 states "Streaming Generation" is the chosen approach (lines 22-33)
+- But atom-feed-specification.md shows `generate()` returning `Iterator[str]` (line 128)
+- JSON Feed spec shows both `generate()` returning complete string AND `generate_streaming()` (lines 188-221)
+- Existing RSS implementation has both methods (feed.py lines 32-126 and 129-227)
+
+**Current Understanding**:
+- ADR says streaming is the architecture decision
+- But implementation may need both for:
+  - Caching (need complete string to store)
+  - Streaming response (memory efficient)
+- Unclear if cache should store complete feeds or not cache at all
+
+**Impact**:
+- Affects generator interface design
+- Determines cache strategy (can't cache generators)
+- Memory efficiency trade-offs
+
+**Proposed Approach**:
+Implement both like existing RSS: `generate()` for complete feed (used with caching), `generate_streaming()` for memory-efficient streaming. Cache stores complete strings from `generate()`. Is this correct?
+
+---
+
+### CQ7: Content Negotiation Default Format
+
+**Question**: What format should be returned if content negotiation fails or client provides no preference?
+
+**Context**:
+- feed-enhancements-spec.md shows default to 'rss' (line 106)
+- But also shows checking `available_formats` (lines 88-106)
+- What if RSS is disabled in config? Should we:
+  1. Always default to RSS even if disabled
+  2. Default to first enabled format
+  3. Return 406 Not Acceptable
+
+**Current Understanding**:
+- RSS seems to be the universal default
+- But config allows disabling formats (architecture doc lines 257-259)
+- Edge case: all formats disabled or only one enabled
+
+**Impact**:
+- Affects error handling strategy
+- Determines configuration validation requirements
+- User experience for misconfigured systems
+
+**Proposed Approach**:
+Default to RSS if enabled, else first enabled format alphabetically. Validate at startup that at least one format is enabled. Return 406 if all disabled and no Accept match. Is this acceptable?
+
+---
+
+### CQ8: OPML Generator Endpoint Location
+
+**Question**: Where should the OPML export endpoint be located, and should it require admin authentication?
+
+**Context**:
+- implementation-guide.md shows route as `/feeds.opml` (line 492)
+- feed-enhancements-spec.md shows `export_opml()` function (line 492)
+- But no specification whether it's:
+  - Public endpoint (anyone can access)
+  - Admin-only endpoint
+  - Part of public routes or admin routes
+
+**Current Understanding**:
+- OPML is just a list of feed URLs
+- Nothing sensitive in the data
+- But unclear if it should be public or admin feature
+
+**Impact**:
+- Determines route registration location
+- Affects security/access control decisions
+- May influence feature discoverability
+
+**Proposed Approach**:
+Make `/feeds.opml` a public endpoint (no auth required) since it only exposes feed URLs which are already public. Place in `routes/public.py`. Is this correct?
+
+---
+
+## Important Questions (Should be answered for Phase 1)
+
+These questions address implementation details, performance considerations, testing approaches, and error handling that are important but not blocking.
+
+### IQ1: Database Query Pattern Detection Accuracy
+
+**Question**: How robust should the table name extraction be in `MonitoredConnection._extract_table_name()`?
+
+**Context**:
+- metrics-instrumentation-spec.md shows regex patterns for common cases (lines 107-113)
+- Comment says "Simple regex patterns" with "Implementation details..."
+- Real SQL can be complex (JOINs, subqueries, CTEs)
+
+**Current Understanding**:
+- Basic regex for FROM, INTO, UPDATE patterns
+- Won't handle complex queries perfectly
+- Unclear if we should:
+  1. Keep it simple (basic patterns only)
+  2. Use SQL parser library (more accurate)
+  3. Return "unknown" for complex queries
+
+**Impact**:
+- Affects metrics usefulness (how often is table "unknown"?)
+- Determines dependencies (SQL parser adds complexity)
+- Testing complexity
+
+**Proposed Approach**:
+Implement simple regex for 90% case, return "unknown" for complex queries. Document limitation. Consider SQL parser library as future enhancement if needed. Acceptable?
+
+---
+
+### IQ2: HTTP Metrics Request ID Generation
+
+**Question**: Should request IDs be exposed in response headers for client debugging, and should they be logged?
+
+**Context**:
+- metrics-instrumentation-spec.md generates request_id (line 151)
+- But doesn't specify if it should be:
+  - Returned in response headers (X-Request-ID)
+  - Logged for correlation
+  - Only internal
+
+**Current Understanding**:
+- Request ID useful for debugging
+- Common pattern to return in header
+- Could help correlate client issues with server logs
+
+**Impact**:
+- Affects HTTP response headers
+- Logging strategy decisions
+- Debugging capabilities
+
+**Proposed Approach**:
+Generate UUID for each request, store in `g.request_id`, add `X-Request-ID` response header, include in error logs. Only in debug mode or always? What do you prefer?
+
+---
+
+### IQ3: Slow Query Threshold Configuration
+
+**Question**: Should the slow query threshold (1 second) be configurable, and should it differ by query type?
+
+**Context**:
+- metrics-instrumentation-spec.md has hardcoded 1.0 second threshold (line 86)
+- Configuration shows `STARPUNK_METRICS_SLOW_QUERY_THRESHOLD=1.0` (line 422)
+- But some queries might reasonably be slower (full table scans for admin)
+
+**Current Understanding**:
+- 1 second is reasonable default
+- But different operations have different expectations:
+  - SELECT with full scan: maybe 2s is okay
+  - INSERT: should be fast, 0.5s threshold?
+- Unclear if one threshold fits all
+
+**Impact**:
+- Affects slow query alert noise
+- Determines configuration complexity
+- May need query-type-specific thresholds
+
+**Proposed Approach**:
+Start with single configurable threshold (1 second default). Add query-type-specific thresholds as v1.2 enhancement if needed. Sound reasonable?
+
+---
+
+### IQ4: Feed Cache Invalidation Timing
+
+**Question**: Should cache invalidation happen synchronously when a note is published/updated, or should we rely solely on TTL expiration?
+
+**Context**:
+- feed-enhancements-spec.md shows `invalidate()` method (lines 273-288)
+- But unclear WHEN to call it
+- Options:
+  1. Call on note create/update/delete (immediate invalidation)
+  2. Rely only on TTL (simpler, 5-minute lag)
+  3. Hybrid: invalidate on note changes, TTL as backup
+
+**Current Understanding**:
+- Checksum-based cache keys mean new notes create new cache entries naturally
+- TTL handles expiration automatically
+- Manual invalidation may be redundant
+
+**Impact**:
+- Affects feed freshness (how quickly new notes appear)
+- Code complexity (invalidation hooks vs. simple TTL)
+- Cache hit rates
+
+**Proposed Approach**:
+Rely on checksum + TTL without manual invalidation. New notes change checksum (new cache key), old entries expire via TTL. Simpler and sufficient. Agree?
+
+---
+
+### IQ5: Statistics Dashboard Chart Library
+
+**Question**: Which JavaScript chart library should be used for the syndication dashboard graphs?
+
+**Context**:
+- implementation-guide.md shows Chart.js example (line 598-610)
+- feed-enhancements-spec.md also shows Chart.js (lines 599-609)
+- But we may already use a chart library elsewhere in the admin UI
+
+**Current Understanding**:
+- Chart.js is simple and popular
+- But adds a dependency
+- Need to check if admin UI already uses charts
+
+**Impact**:
+- Determines JavaScript dependencies
+- Affects admin UI consistency
+- Bundle size considerations
+
+**Proposed Approach**:
+Check current admin UI for existing chart library. If none, use Chart.js (lightweight, simple). If we already use something else, use that. Need to review admin templates first. Should I?
+
+---
+
+### IQ6: ATOM Content Type Selection Logic
+
+**Question**: How should the ATOM generator decide between `type="text"`, `type="html"`, and `type="xhtml"` for content?
+
+**Context**:
+- atom-feed-specification.md shows three content types (lines 283-306)
+- Implementation shows checking `note.html` existence (lines 205-214)
+- But doesn't specify when to use XHTML (marked as "Future")
+
+**Current Understanding**:
+- If `note.html` exists: use `type="html"` with escaping
+- If only plain text: use `type="text"`
+- XHTML type is deferred to future
+
+**Impact**:
+- Affects content rendering in feed readers
+- Determines XML structure
+- XHTML support complexity
+
+**Proposed Approach**:
+For v1.1.2, only implement `type="text"` (escaped) and `type="html"` (escaped). Skip `type="xhtml"` for now. Document as future enhancement. Is this acceptable?
+
+---
+
+### IQ7: JSON Feed Custom Extensions Scope
+
+**Question**: What should go in the `_starpunk` custom extension besides permalink_path and word_count?
+
+**Context**:
+- json-feed-specification.md shows custom extension (lines 290-293)
+- Only includes `permalink_path` and `word_count`
+- But we could include other StarPunk-specific data:
+  - Note slug
+  - Note UUID
+  - Tags (though tags are in standard `tags` field)
+  - Syndication targets
+
+**Current Understanding**:
+- Minimal extension with just basic metadata
+- Unclear if we should add more StarPunk-specific fields
+- JSON Feed spec allows any custom fields with underscore prefix
+
+**Impact**:
+- Affects feed schema evolution
+- API stability considerations
+- Client compatibility
+
+**Proposed Approach**:
+Keep it minimal for v1.1.2 (just permalink_path and word_count as shown). Add more fields in v1.2 if user feedback requests them. Document extension schema. Agree?
+
+---
+
+### IQ8: Memory Monitor Baseline Timing
+
+**Question**: The memory monitor waits 5 seconds for baseline (metrics-instrumentation-spec.md line 217). Is this sufficient for Flask app initialization?
+
+**Context**:
+- App initialization involves:
+  - Database connection pool creation
+  - Template loading
+  - Route registration
+  - First request may trigger additional loading
+- 5 seconds may not capture "steady state"
+
+**Current Understanding**:
+- Baseline needed to calculate growth rate
+- 5 seconds is arbitrary
+- First request often allocates more memory (template compilation, etc.)
+
+**Impact**:
+- Affects memory leak detection accuracy
+- False positives if baseline too early
+- Determines monitoring reliability
+
+**Proposed Approach**:
+Wait 5 seconds PLUS wait for first HTTP request completion before setting baseline. This ensures app is "warmed up". Does this make sense?
+
+---
+
+### IQ9: Feed Validation Integration
+
+**Question**: Should feed validation be:
+1. Automatic on every generation (validates output)
+2. Manual via admin endpoint
+3. Only in tests
+
+**Context**:
+- implementation-guide.md mentions validation framework (lines 332-365)
+- Validators for each format (RSS, ATOM, JSON)
+- But unclear if validation runs in production or just tests
+
+**Current Understanding**:
+- Validation adds overhead
+- Useful for testing and development
+- But may be too slow for production
+
+**Impact**:
+- Performance impact on feed generation
+- Error handling strategy (what if validation fails?)
+- Development/debugging workflow
+
+**Proposed Approach**:
+Implement validators for testing only. Optionally enable in debug mode. Add admin endpoint `/admin/validate-feeds` for manual validation. Skip in production for performance. Sound good?
+
+---
+
+### IQ10: Syndication Statistics Retention
+
+**Question**: The architecture doc mentions 7-day retention (line 279), but how should old statistics be pruned?
+
+**Context**:
+- SyndicationStats collects metrics in memory (feed-enhancements-spec.md lines 387-478)
+- Uses deque with maxlen for some data (errors)
+- But counters and histograms grow unbounded
+- 7-day retention mentioned but no pruning mechanism shown
+
+**Current Understanding**:
+- In-memory stats grow over time
+- Need periodic cleanup or rotation
+- But no specification for HOW to prune
+
+**Impact**:
+- Memory leak potential
+- Data accuracy over time
+- Dashboard performance with large datasets
+
+**Proposed Approach**:
+Add timestamp to all metrics, implement periodic cleanup (daily cron-like task) to remove data older than 7 days. Store in time-bucketed structure for efficient pruning. Is this the right approach?
+
+---
+
+## Nice-to-Have Clarifications (Can defer if needed)
+
+These questions address optimizations, future enhancements, and documentation details that don't block implementation.
+
+### NH1: Performance Benchmark Automation
+
+**Question**: Should performance benchmarks be automated in CI/CD, or just manual developer tests?
+
+**Context**:
+- Multiple specs include benchmark examples
+- atom-feed-specification.md has benchmark functions (lines 458-489)
+- But unclear if these should run in CI
+
+**Current Understanding**:
+- Benchmarks help ensure performance targets met
+- But may be flaky in CI environment
+- Could add to test suite but not as gate
+
+**Impact**:
+- CI/CD pipeline complexity
+- Performance regression detection
+- Development workflow
+
+**Proposed Approach**:
+Create benchmark test suite, mark as `@pytest.mark.benchmark`, run manually or optionally in CI. Don't block merges on benchmark results. Make it opt-in. Acceptable?
+
+---
+
+### NH2: Feed Format Feature Parity
+
+**Question**: Should all three formats (RSS, ATOM, JSON) expose exactly the same data, or can they differ based on format capabilities?
+
+**Context**:
+- RSS: Basic fields (title, description, link, date)
+- ATOM: Richer (author objects, categories, updated vs published)
+- JSON: Most flexible (attachments, custom extensions)
+
+**Current Understanding**:
+- Each format has different capabilities
+- Should we limit to common denominator or leverage format strengths?
+
+**Impact**:
+- User experience varies by format choice
+- Implementation complexity
+- Testing matrix
+
+**Proposed Approach**:
+Leverage format strengths: include author in ATOM, custom extensions in JSON, keep RSS basic. Document differences in feed format comparison. Users can choose based on needs. Okay?
+
+---
+
+### NH3: Content Negotiation Quality Factor Scoring
+
+**Question**: The negotiation algorithm (feed-enhancements-spec.md lines 141-166) shows wildcard scoring. Should we support more nuanced quality factor logic?
+
+**Context**:
+- Current logic: exact=1.0, wildcard=0.1, type/*=0.5
+- Quality factors multiply these scores
+- But clients might send complex preferences like:
+  `application/atom+xml;q=0.9, application/rss+xml;q=0.8, application/json;q=0.7`
+
+**Current Understanding**:
+- Simple scoring algorithm shown
+- May not handle all edge cases
+- But probably good enough for feed readers
+
+**Impact**:
+- Content negotiation accuracy
+- Complex client preference handling
+- Testing complexity
+
+**Proposed Approach**:
+Keep simple algorithm as specified. If real-world edge cases emerge, enhance in v1.2. Log negotiation decisions in debug mode for troubleshooting. Sufficient?
+
+---
+
+### NH4: Cache Statistics Persistence
+
+**Question**: Should cache statistics survive application restarts?
+
+**Context**:
+- feed-enhancements-spec.md shows in-memory stats (lines 213-220)
+- Stats reset on restart
+- Dashboard shows historical data
+
+**Current Understanding**:
+- All stats in memory (lost on restart)
+- Simplest implementation
+- But loses historical trends
+
+**Impact**:
+- Historical analysis capability
+- Dashboard usefulness over time
+- Storage complexity if we add persistence
+
+**Proposed Approach**:
+Keep stats in memory for v1.1.2. Document that stats reset on restart. Consider SQLite persistence in v1.2 if users request it. Defer for now?
+
+---
+
+### NH5: Feed Reader User Agent Detection Patterns
+
+**Question**: The regex patterns for user agent normalization (feed-enhancements-spec.md lines 459-476) are basic. Should we use a user-agent parsing library?
+
+**Context**:
+- Simple regex patterns for common readers
+- But user agents can be complex and varied
+- Libraries like `user-agents` exist
+
+**Current Understanding**:
+- Regex covers major feed readers
+- Library adds dependency
+- Trade-off: accuracy vs. simplicity
+
+**Impact**:
+- Statistics accuracy
+- Dependencies
+- Maintenance burden (regex needs updates)
+
+**Proposed Approach**:
+Start with regex patterns, log unknown user agents, update patterns as needed. Add library later if regex becomes unmaintainable. Star with simple. Okay?
+
+---
+
+### NH6: OPML Multiple Feed Organization
+
+**Question**: Should OPML export support grouping feeds by category or just flat list?
+
+**Context**:
+- Current spec shows flat outline list (feed-enhancements-spec.md lines 707-723)
+- OPML supports nested outlines for categorization
+- Could group by format: "RSS Feeds", "ATOM Feeds", "JSON Feeds"
+
+**Current Understanding**:
+- Flat list is simplest
+- Three feeds (RSS, ATOM, JSON) probably don't need grouping
+- But OPML spec supports it
+
+**Impact**:
+- OPML complexity
+- User experience in feed readers
+- Future extensibility (custom feeds)
+
+**Proposed Approach**:
+Keep flat list for v1.1.2 (just 3 feeds). Add optional grouping in v1.2 if we add custom feeds or filters. YAGNI for now. Agree?
+
+---
+
+### NH7: Streaming Chunk Size Optimization
+
+**Question**: The architecture doc mentions 4KB chunk size (line 253). Should this be configurable or optimized per format?
+
+**Context**:
+- ADR-054 specifies 4KB streaming chunks (line 253)
+- But different formats have different structure:
+  - RSS/ATOM: XML entries vary in size
+  - JSON: Object-based structure
+- May want format-specific chunk strategies
+
+**Current Understanding**:
+- 4KB is reasonable default
+- Generators yield semantic chunks (whole items), not byte chunks
+- HTTP layer may buffer differently anyway
+
+**Impact**:
+- Memory efficiency trade-offs
+- Network performance
+- Implementation complexity
+
+**Proposed Approach**:
+Don't enforce strict 4KB chunks. Let generators yield semantic units (complete entries/items). Let Flask/HTTP layer handle buffering. Document approximate chunk sizes. Flexible approach okay?
+
+---
+
+### NH8: Error Handling for Feed Generation Failures
+
+**Question**: What should happen if feed generation fails midway through streaming?
+
+**Context**:
+- Streaming sends response headers immediately
+- If error occurs mid-stream, headers already sent
+- Can't return 500 status code at that point
+
+**Current Understanding**:
+- Streaming commits to response early
+- Errors mid-stream are problematic
+- Need error handling strategy
+
+**Impact**:
+- Error recovery UX
+- Client handling of partial feeds
+- Logging and alerting
+
+**Proposed Approach**:
+1. Validate inputs before streaming starts
+2. If error mid-stream, log error and truncate feed (may be invalid XML/JSON)
+3. Monitor error logs for generation failures
+4. Consider pre-generating to memory if errors are common (defeats streaming)
+
+Is this acceptable, or should we always generate to memory first?
+
+---
+
+### NH9: Metrics Dashboard Auto-Refresh
+
+**Question**: Should the syndication dashboard auto-refresh, and if so, at what interval?
+
+**Context**:
+- Dashboard shows live statistics (feed-enhancements-spec.md lines 483-611)
+- Stats change as requests come in
+- But no auto-refresh specified
+
+**Current Understanding**:
+- Manual refresh okay for admin UI
+- Auto-refresh could be nice
+- But adds JavaScript complexity
+
+**Impact**:
+- User experience for monitoring
+- JavaScript dependencies
+- Server load (polling)
+
+**Proposed Approach**:
+No auto-refresh for v1.1.2. Admin can manually refresh browser. Add auto-refresh in v1.2 if requested. Keep it simple. Fine?
+
+---
+
+### NH10: Configuration Validation for Feed Settings
+
+**Question**: Should feed configuration be validated at startup (fail-fast), or allow invalid config with runtime errors?
+
+**Context**:
+- Many new config options (implementation-guide.md lines 549-563)
+- Some interdependent (ENABLED flags, cache sizes, TTLs)
+- Current `validate_config()` in config.py validates basics
+
+**Current Understanding**:
+- Config validation exists for core settings
+- Need to extend for feed settings
+- But unclear how strict to be
+
+**Impact**:
+- Error discovery timing (startup vs. runtime)
+- Configuration flexibility
+- Development experience
+
+**Proposed Approach**:
+Add feed config validation to `validate_config()`:
+- At least one format enabled
+- Positive integers for cache size, TTL, limits
+- Warn if cache TTL very short (<60s) or very long (>3600s)
+- Fail fast on startup
+
+Is this the right level of validation?
+
+---
+
+## Summary and Next Steps
+
+**Total Questions**: 30
+- Critical (blocking): 8
+- Important (Phase 1): 10
+- Nice-to-Have (deferrable): 12
+
+**Priority for Architect**:
+1. Answer critical questions first (CQ1-CQ8) - these block implementation start
+2. Review important questions (IQ1-IQ10) - needed for Phase 1 quality
+3. Nice-to-have questions (NH1-NH10) - can defer or apply judgment
+
+**Developer's Current Understanding**:
+After thorough review of all specifications, I understand the overall architecture and design intent. The questions primarily focus on:
+- Integration points with existing code
+- Ambiguities in specifications
+- Edge cases and error handling
+- Configuration and lifecycle management
+- Trade-offs between simplicity and features
+
+**Ready to Implement**:
+Once critical questions are answered, I can begin Phase 1 implementation (Metrics Instrumentation) with confidence. The important questions can be answered during Phase 1 development, and nice-to-have questions can be deferred.
+
+**Request to Architect**:
+Please prioritize answering CQ1-CQ8 first. For the others, feel free to provide brief guidance or "use your judgment" if the answer is obvious. I'll create follow-up questions document after Phase 1 if new issues emerge.
+
+Thank you for the thorough design documentation - it makes implementation much clearer!

+## Content Negotiation
+
+### Design
+
+Content negotiation determines the best feed format based on the client's Accept header.

+### Accept Header Examples
+
+| Accept Header | Selected Format | Reason |
+|--------------|-----------------|--------|
+| `application/atom+xml` | atom | Exact match |
+| `application/json` | json | JSON match |
+| `application/rss+xml, application/atom+xml;q=0.9` | rss | Higher quality |
+| `text/html, application/*;q=0.9` | rss | Wildcard match, RSS default |
+| `*/*` | rss | No preference, use default |
+| (empty) | rss | No header, use default |

+
+## Testing Strategy
+
+### Content Negotiation Tests
+
+```python
+def test_content_negotiation():
+    """Test Accept header parsing and format selection"""
+    negotiator = ContentNegotiator()
+
+    # Test exact matches
+    assert negotiator.negotiate('application/atom+xml') == 'atom'
+    assert negotiator.negotiate('application/feed+json') == 'json'
+    assert negotiator.negotiate('application/rss+xml') == 'rss'
+
+    # Test quality factors
+    assert negotiator.negotiate('application/atom+xml;q=0.8, application/rss+xml') == 'rss'
+
+    # Test wildcards
+    assert negotiator.negotiate('*/*') == 'rss'  # Default
+    assert negotiator.negotiate('application/*') == 'rss'  # First application type
+
+    # Test no preference
+    assert negotiator.negotiate('') == 'rss'
+    assert negotiator.negotiate('text/html') == 'rss'
+```
+
+### Cache Tests
+
+```python
+def test_feed_cache():
+    """Test LRU cache with TTL"""
+    cache = FeedCache(max_size=3, default_ttl=1)
+
+    # Test set and get
+    cache.set('rss', 50, 'abc123', '<rss>content</rss>', 'application/rss+xml')

+    # Test LRU eviction
+    cache.set('rss', 50, 'aaa', 'content1', 'application/rss+xml')
+    cache.set('atom', 50, 'bbb', 'content2', 'application/atom+xml')
+    cache.set('json', 50, 'ccc', 'content3', 'application/json')
+    cache.set('rss', 100, 'ddd', 'content4', 'application/rss+xml')  # Evicts oldest
+
+    assert cache.get('rss', 50, 'aaa') is None  # Evicted
+    assert cache.get('atom', 50, 'bbb') is not None  # Still present
+```
+
+### Statistics Tests
+
+```python
+def test_syndication_stats():
+    """Test statistics collection"""
+    stats = SyndicationStats()
+
+    # Record requests
+    stats.record_request('rss', 'Feedly/1.0', cached=False, generation_time=0.05)

+    assert summary['total_requests'] == 3
+    assert 'rss' in summary['format_distribution']
+    assert len(summary['top_user_agents']) > 0
+```
+
+### OPML Tests
+
+```python
+def test_opml_generation():
+    """Test OPML export"""
+    generator = OPMLGenerator(
+        site_url='https://example.com',
+        site_name='Test Site',

+    assert outlines[2].get('type') == 'json'
+```
+
+## Performance Benchmarks
+
+### Negotiation Performance
+
+```python
+def benchmark_content_negotiation():
+    """Benchmark negotiation speed"""
+    negotiator = ContentNegotiator()
+    complex_header = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'
+

+    for _ in range(10000):
+        negotiator.negotiate(complex_header)
+    duration = time.perf_counter() - start
+
+    per_call = (duration / 10000) * 1000  # Convert to ms
+    assert per_call < 1.0  # Less than 1ms per negotiation
+```
+
+## Configuration
+
+```ini
+# Content negotiation
+STARPUNK_FEED_NEGOTIATION_ENABLED=true
+STARPUNK_FEED_DEFAULT_FORMAT=rss
+
+# Cache settings
+STARPUNK_FEED_CACHE_ENABLED=true
+STARPUNK_FEED_CACHE_SIZE=100
+STARPUNK_FEED_CACHE_TTL=300
+STARPUNK_FEED_CACHE_MEMORY_LIMIT=10  # MB

+# Statistics
+STARPUNK_FEED_STATS_ENABLED=true
+STARPUNK_FEED_STATS_RETENTION=7  # days
+
+# OPML
+STARPUNK_FEED_OPML_ENABLED=true
+STARPUNK_FEED_OPML_OWNER_NAME=
+STARPUNK_FEED_OPML_OWNER_EMAIL=
+```
+
+## Security Considerations
+
+1. **Cache Poisoning**: Validate all cached content
+2. **Header Injection**: Sanitize Accept headers
+3. **Memory Exhaustion**: Limit cache size
+4. **Statistics Privacy**: Don't log sensitive data
+5. **OPML Injection**: Escape all XML content
+
+## Acceptance Criteria
+
+1. ✅ Content negotiation working correctly
+2. ✅ Cache hit rate >80% achieved
+3. ✅ Statistics dashboard functional
+4. ✅ OPML export valid
+5. ✅ Memory usage bounded
+6. ✅ Performance targets met
+7. ✅ All formats properly cached
+8. ✅ Invalidation working
+9. ✅ User agent detection accurate
+10. ✅ Security review passed

+# StarPunk v1.1.2 "Syndicate" - Implementation Guide
+
+## Overview
+
+This guide provides a phased approach to implementing v1.1.2 "Syndicate" features. The release is structured in three phases totaling 14-16 hours of focused development.
+
+## Pre-Implementation Checklist
+
+- [x] Review v1.1.1 performance monitoring specification
+- [x] Ensure development environment has Python 3.11+
+- [x] Create feature branch: `feature/v1.1.2-syndicate`
+- [ ] Review feed format specifications (RSS 2.0, ATOM 1.0, JSON Feed 1.1)
+- [ ] Set up feed reader test clients
+
+## Phase 1: Metrics Instrumentation (4-6 hours) ✅ COMPLETE
+
+### Objective
+Complete the metrics instrumentation that was partially implemented in v1.1.1, adding comprehensive coverage across all system operations.
+
+### 1.1 Database Operation Timing (1.5 hours) ✅
+
+**Location**: `starpunk/monitoring/database.py`
+
+**Implementation Steps**:
+
+1. **Create Database Monitor Wrapper**
+   ```python
+   class MonitoredConnection:
+       """Wrapper for SQLite connections with timing"""
+
+       def execute(self, query, params=None):
+           # Start timer
+           # Execute query
+           # Record metric
+           # Return result
+   ```
+
+2. **Instrument All Query Types**
+   - SELECT queries (with row count)
+   - INSERT operations (with affected rows)
+   - UPDATE operations (with affected rows)

+
+## Phase 2: Feed Formats (6-8 hours)
+
+### Objective
+Fix RSS feed ordering regression, then implement ATOM and JSON Feed formats alongside existing RSS, with proper content negotiation and caching.
+
+### 2.0 Fix RSS Feed Ordering Regression (0.5 hours) - CRITICAL
+
+**Location**: `starpunk/feed.py`
+
+**Critical Production Bug**: RSS feed currently shows oldest entries first instead of newest first. This violates RSS standards and user expectations.
+
+**Root Cause**: Incorrect `reversed()` calls on lines 100 and 198 that flip the correct DESC order from database.
+
+**Implementation Steps**:
+
+1. **Remove Incorrect Reversals**
+   - Line 100: Remove `reversed()` from `for note in reversed(notes[:limit]):`
+   - Line 198: Remove `reversed()` from `for note in reversed(notes[:limit]):`
+   - Update/remove misleading comments about feedgen reversing order
+
+2. **Verify Expected Behavior**
+   - Database returns notes in DESC order (newest first) - confirmed line 440 of notes.py
+   - Feed should maintain this order (newest entries first)
+   - This is the standard for ALL feed formats (RSS, ATOM, JSON Feed)
+
+3. **Add Feed Order Tests**
+   ```python
+   def test_rss_feed_newest_first():
+       """Test RSS feed shows newest entries first"""
+       # Create notes with different timestamps
+       old_note = create_note(title="Old", created_at=yesterday)
+       new_note = create_note(title="New", created_at=today)
+
+       # Generate feed
+       feed = generate_rss_feed([old_note, new_note])
+
+       # Parse and verify order
+       items = parse_feed_items(feed)
+       assert items[0].title == "New"
+       assert items[1].title == "Old"
+   ```
+
+**Important**: This MUST be fixed before implementing ATOM and JSON feeds to ensure all formats have consistent, correct ordering.
+
+### 2.1 ATOM Feed Generation (2.5 hours)
+
+**Location**: `starpunk/feed/atom.py`
+
+**Implementation Steps**:
+
+1. **Create ATOM Generator Class**
+   ```python
+   class AtomGenerator:
+       def generate(self, notes, config):
+           # Yield XML declaration
+           # Yield feed element
+           # Yield entries
+           # Stream output
+   ```
+
+2. **Implement ATOM 1.0 Elements**
+   - Required: id, title, updated
+   - Recommended: author, link, category
+   - Optional: contributor, generator, icon, logo, rights, subtitle
+
+3. **Handle Content Types**
+   - Text content (escaped)
+   - HTML content (in CDATA)
+   - XHTML content (inline)
+   - Base64 for binary
+
+4. **Date Formatting**
+   - RFC 3339 format
+   - Timezone handling
+   - Updated vs published
+
+**ATOM Structure**:
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<feed xmlns="http://www.w3.org/2005/Atom">
+  <title>Site Title</title>
+  <link href="http://example.com/"/>
+  <link href="http://example.com/feed.atom" rel="self"/>
+  <updated>2024-11-25T12:00:00Z</updated>
+  <author>
+    <name>Author Name</name>
+  </author>
+  <id>http://example.com/</id>

+## Validation
+
+### JSON Feed Validator
+
+Validate against the official validator:
+- https://validator.jsonfeed.org/
+
+### Common Validation Issues
+
+1. **Invalid JSON Syntax**
+   - Proper escaping of quotes
+   - Valid UTF-8 encoding
+   - No trailing commas
+
+2. **Missing Required Fields**
+   - version, title, items required
+   - Each item needs id
+
+3. **Invalid Date Format**
+   - Must be RFC 3339
+   - Include timezone
+
+4. **Invalid URLs**
+   - Must be absolute URLs
+   - Properly encoded

+    # Typically JSON is 20-30% smaller
+```
+
+## Configuration
+
+### JSON Feed Settings
+
+```ini
+# JSON Feed configuration
+STARPUNK_FEED_JSON_ENABLED=true
+STARPUNK_FEED_JSON_AUTHOR_NAME=John Doe
+STARPUNK_FEED_JSON_AUTHOR_URL=https://example.com/about
+STARPUNK_FEED_JSON_AUTHOR_AVATAR=https://example.com/avatar.jpg
+STARPUNK_FEED_JSON_ICON=https://example.com/icon.png
+STARPUNK_FEED_JSON_FAVICON=https://example.com/favicon.ico
+STARPUNK_FEED_JSON_LANGUAGE=en
+STARPUNK_FEED_JSON_HUB_URL=  # WebSub hub URL (optional)
+```
+
+## Security Considerations
+
+1. **JSON Injection Prevention**
+   - Proper JSON escaping
+   - No raw user input
+   - Validate all URLs
+
+2. **Content Security**
+   - HTML content sanitized
+   - No script injection
+   - Safe JSON encoding
+
+3. **Size Limits**
+   - Maximum feed size
+   - Item count limits
+   - Timeout protection
+
+## Migration Notes
+
+### Adding JSON Feed
+
+- Runs parallel to RSS/ATOM
+- No changes to existing feeds
+- Shared caching infrastructure
+- Same data source
+
+## Advanced Features
+
+### WebSub Support (Future)
+
+```json
+{
+  "hubs": [
+    {
+      "type": "WebSub",
+      "url": "https://example.com/hub"
+    }
+  ]
+}
+```
+
+### Pagination
+
+```json
+{
+  "next_url": "https://example.com/feed.json?page=2"
+}
+```
+
+### Attachments
+
+```json
+{
+  "attachments": [
+    {
+      "url": "https://example.com/podcast.mp3",
+      "mime_type": "audio/mpeg",
+      "title": "Podcast Episode",
+      "size_in_bytes": 25000000,
+      "duration_in_seconds": 1800
+    }
+  ]
+}
+```

+# Metrics Instrumentation Specification - v1.1.2
+
+## Overview
+
+This specification completes the metrics instrumentation foundation started in v1.1.1, adding comprehensive coverage for database operations, HTTP requests, memory monitoring, and business-specific syndication metrics.
+
+## Requirements
+
+### Functional Requirements
+
+1. **Database Performance Metrics**
+   - Time all database operations
+   - Track query patterns and frequency
+   - Detect slow queries (>1 second)
+   - Monitor connection pool utilization
+   - Count rows affected/returned
+
+2. **HTTP Request/Response Metrics**
+   - Full request lifecycle timing
+   - Request and response size tracking
+   - Status code distribution
+   - Per-endpoint performance metrics
+   - Client identification (user agent)
+
+3. **Memory Monitoring**
+   - Continuous RSS memory tracking
+   - Memory growth detection
+   - High water mark tracking
+   - Garbage collection statistics
+   - Leak detection algorithms
+
+4. **Business Metrics**
+   - Feed request counts by format
+   - Cache hit/miss rates
+   - Content publication rates
+   - Syndication success tracking
+   - Format popularity analysis
+
+### Non-Functional Requirements
+
+1. **Performance Impact**
+   - Total overhead <1% when enabled
+   - Zero impact when disabled
+   - Efficient metric storage (<2MB)
+   - Non-blocking collection
+
+2. **Data Retention**
+   - In-memory circular buffer
+   - Last 1000 metrics retained
+   - 15-minute detail window
+   - Automatic cleanup
+

+       monitor = MemoryMonitor(collector)
+       monitor.start()
+
+       # Simulate memory growth
+       large_list = [0] * 1000000
+       time.sleep(15)
+
+       metrics = collector.get_summary()
+       assert metrics['gauges']['memory.rss'] > 0
+   ```
+
+## Performance Benchmarks
+
+### Overhead Measurement
+
+```python
+def benchmark_instrumentation_overhead():
+    # Baseline without instrumentation
+    config.METRICS_ENABLED = False
+    start = time.perf_counter()
+    for _ in range(1000):
+        execute_operation()
+    baseline = time.perf_counter() - start
+
+    # With instrumentation
+    config.METRICS_ENABLED = True
+    start = time.perf_counter()
+    for _ in range(1000):
+        execute_operation()
+    instrumented = time.perf_counter() - start
+
+    overhead_percent = ((instrumented - baseline) / baseline) * 100
+    assert overhead_percent < 1.0  # Less than 1% overhead
+```
+
+## Security Considerations
+
+1. **No Sensitive Data**: Never log query parameters that might contain passwords
+2. **Rate Limiting**: Metrics endpoints should be rate-limited
+3. **Access Control**: Metrics dashboard requires admin authentication
+4. **Data Sanitization**: Escape all user-provided data in metrics
+
+## Migration Notes
+
+### From v1.1.1
+
+- Existing performance monitoring configuration remains compatible
+- New metrics are additive, no breaking changes
+- Dashboard enhanced but backward compatible
+
+## Acceptance Criteria
+
+1. ✅ All database operations are timed
+2. ✅ HTTP requests fully instrumented
+3. ✅ Memory monitoring thread operational
+4. ✅ Business metrics for syndication tracked
+5. ✅ Performance overhead <1%
+6. ✅ Metrics dashboard shows all new data
+7. ✅ Slow query detection working
+8. ✅ Memory leak detection functional
+9. ✅ All metrics properly documented
+10. ✅ Security review passed

+# CSS Design for Media Display (v1.2.0)
+
+## Status
+**Superseded by media-display-fixes.md**
+
+This document contains an earlier design iteration. The authoritative specification is now in `media-display-fixes.md` which provides a more comprehensive solution including template refactoring and consistent media display across all pages.
+
+## Problem Statement
+Images uploaded via the media upload feature display at full resolution, breaking layout bounds and creating poor user experience. Need CSS rules to constrain and style images appropriately.
+
+## Design Decision
+
+### CSS Rules to Add
+
+Add the following CSS rules after line 49 (after `.empty-state` rules) in `/home/phil/Projects/starpunk/static/css/style.css`:
+
+```css
+/* Media Display Styles (v1.2.0) */
+.note-media { margin-bottom: var(--spacing-md); }
+.note-media figure, .e-content figure { margin: 0 0 var(--spacing-md) 0; }
+.note-media img, .e-content img, .u-photo { max-width: 100%; height: auto; display: block; border-radius: var(--border-radius); }
+.note-media figcaption, .e-content figcaption { margin-top: var(--spacing-sm); font-size: 0.875rem; color: var(--color-text-light); font-style: italic; }
+
+/* Multiple media items grid */
+.note-media { display: flex; flex-wrap: wrap; gap: var(--spacing-md); }
+.note-media .media-item { flex: 1 1 100%; }
+
+/* Desktop: side-by-side for multiple images */
+@media (min-width: 768px) {
+  .note-media .media-item:only-child { flex: 1 1 100%; }
+  .note-media .media-item:not(:only-child) { flex: 1 1 calc(50% - var(--spacing-sm)); }
+}
+```
+
+## Rationale
+
+### 1. Responsive Image Constraints
+- `max-width: 100%` ensures images never exceed container width
+- `height: auto` maintains aspect ratio
+- `display: block` removes inline spacing issues
+- Works with existing HTML `width` and `height` attributes for proper aspect ratio hints
+
+### 2. Consistent Visual Design
+- `border-radius: var(--border-radius)` matches existing design system (4px)
+- Uses existing spacing variables for consistent margins
+- Caption styling matches `.note-meta` text style (0.875rem, light gray)
+
+### 3. Flexible Layout
+- Single images take full width
+- Multiple images display in a responsive grid
+- Mobile: stacked vertically (100% width each)
+- Desktop: two columns for multiple images (50% width each)
+- Flexbox with gap provides clean spacing
+
+### 4. Scope Coverage
+- `.note-media img` - images in the media section
+- `.e-content img` - images in markdown content
+- `.u-photo` - microformats photo class (covers both media and author photos)
+- Applies to both `figure` and standalone `img` elements
+
+### 5. Performance Considerations
+- No complex calculations or transforms
+- Leverages browser native image sizing
+- Uses existing CSS variables (no new computations)
+- Respects HTML width/height attributes for layout stability
+
+## Alternative Approaches Considered
+
+### Object-fit Approach (Rejected)
+```css
+img { object-fit: cover; width: 100%; height: 400px; }
+```
+- Rejected: Crops images, losing content
+- Rejected: Fixed height doesn't work for varied aspect ratios
+
+### Container Query Approach (Rejected)
+```css
+@container (min-width: 600px) { ... }
+```
+- Rejected: Limited browser support
+- Rejected: Unnecessary complexity for this use case
+
+### CSS Grid Approach (Rejected)
+```css
+.note-media { display: grid; grid-template-columns: repeat(auto-fit, minmax(300px, 1fr)); }
+```
+- Rejected: More complex than needed
+- Rejected: Less flexible for single vs multiple images
+
+## Implementation Notes
+
+1. **Location in style.css**: Insert after line 49, before `.form-group` rules
+2. **Testing Required**:
+   - Single image display
+   - Multiple images (2, 3, 4 images)
+   - Portrait and landscape orientations
+   - Mobile and desktop viewports
+   - Images in markdown content
+   - Author avatar photos
+
+3. **Browser Compatibility**: All rules use widely supported CSS features (flexbox, max-width, CSS variables)
+
+4. **Future Enhancements** (not for v1.2.0):
+   - Lightbox/modal for full-size viewing
+   - Lazy loading optimization
+   - WebP format support
+   - Image galleries with thumbnails
+
+## Standards Compliance
+
+- **IndieWeb**: Preserves `.u-photo` microformat class
+- **Accessibility**: Maintains alt text display, proper figure/figcaption semantics
+- **Performance**: No JavaScript required, pure CSS solution
+- **Progressive Enhancement**: Images remain functional without CSS

+# v1.2.0 Developer Q&A
+
+**Date**: 2025-11-28
+**Architect**: StarPunk Architect Subagent
+**Purpose**: Answer critical implementation questions for v1.2.0
+
+## Custom Slugs Answers
+
+**Q1: Validation pattern conflict - should we apply new lowercase validation to existing slugs?**
+- **Answer:** Validate only new custom slugs, don't migrate existing slugs
+- **Rationale:** Existing slugs work, no need to change them retroactively
+- **Implementation:** In `validate_and_sanitize_custom_slug()`, apply lowercase enforcement only to new/edited slugs
+
+**Q2: Form field readonly behavior - how should the slug field behave on edit forms?**
+- **Answer:** Display as readonly input field with current value visible
+- **Rationale:** Users need to see the current slug but understand it cannot be changed
+- **Implementation:** Use `readonly` attribute, not `disabled` (disabled fields don't submit with form)
+
+**Q3: Slug uniqueness validation - where should this happen?**
+- **Answer:** Both client-side (for UX) and server-side (for security)
+- **Rationale:** Client-side prevents unnecessary submissions, server-side is authoritative
+- **Implementation:** Database unique constraint + Python validation in `validate_and_sanitize_custom_slug()`
+
+## Media Upload Answers
+
+**Q4: Media upload flow - how should upload and note association work?**
+- **Answer:** Upload during note creation, associate via note_id after creation
+- **Rationale:** Simpler than pre-upload with temporary IDs
+- **Implementation:** Upload files in `create_note_submit()` after note is created, store associations in media table
+
+**Q5: Storage directory structure - exact path format?**
+- **Answer:** `data/media/YYYY/MM/filename-uuid.ext`
+- **Rationale:** Date organization helps with backups and management
+- **Implementation:** Use `os.makedirs(path, exist_ok=True)` to create directories as needed
+
+**Q6: File naming convention - how to ensure uniqueness?**
+- **Answer:** `{original_name_slug}-{uuid4()[:8]}.{extension}`
+- **Rationale:** Preserves original name for SEO while ensuring uniqueness
+- **Implementation:** Slugify original filename, append 8-char UUID, preserve extension
+
+**Q7: MIME type validation - which types exactly?**
+- **Answer:** Allow: image/jpeg, image/png, image/gif, image/webp. Reject all others
+- **Rationale:** Common web formats only, no SVG (XSS risk)
+- **Implementation:** Use python-magic for reliable MIME detection, not just file extension
+
+**Q8: Upload size limits - what's reasonable?**
+- **Answer:** 10MB per file, 40MB total per note (4 files × 10MB)
+- **Rationale:** Sufficient for high-quality images without overwhelming storage
+- **Implementation:** Check in both client-side JavaScript and server-side validation
+
+**Q9: Database schema for media table - exact columns?**
+- **Answer:** id, note_id, filename, mime_type, size_bytes, width, height, uploaded_at
+- **Rationale:** Minimal but sufficient metadata for display and management
+- **Implementation:** Use Pillow to extract image dimensions on upload
+
+**Q10: Orphaned file cleanup - how to handle?**
+- **Answer:** Keep orphaned files, add admin cleanup tool in future version
+- **Rationale:** Data preservation is priority, cleanup can be manual for v1.2.0
+- **Implementation:** Log orphaned files but don't auto-delete
+
+**Q11: Upload progress indication - required for v1.2.0?**
+- **Answer:** No, simple form submission is sufficient for v1.2.0
+- **Rationale:** Keep it simple, can enhance in future version
+- **Implementation:** Standard HTML form with enctype="multipart/form-data"
+
+**Q12: Image display order - how to maintain?**
+- **Answer:** Use upload sequence, store display_order in media table
+- **Rationale:** Predictable and simple
+- **Implementation:** Auto-increment display_order starting at 0
+
+**Q13: Thumbnail generation - needed for v1.2.0?**
+- **Answer:** No, use CSS for responsive sizing
+- **Rationale:** Simplicity over optimization for v1
+- **Implementation:** Use `max-width: 100%` and lazy loading
+
+**Q14: Edit form media handling - can users remove media?**
+- **Answer:** Yes, checkbox to mark for deletion
+- **Rationale:** Essential editing capability
+- **Implementation:** "Remove" checkboxes next to each image in edit form
+
+**Q15: Media URL structure - exact format?**
+- **Answer:** `/media/YYYY/MM/filename.ext` (matches storage path)
+- **Rationale:** Clean URLs, date organization visible
+- **Implementation:** Route in `starpunk/routes/public.py` using send_from_directory
+
+## Author Discovery Answers
+
+**Q16: Discovery failure handling - what if profile URL is unreachable?**
+- **Answer:** Use defaults: name from IndieAuth me URL domain, no photo
+- **Rationale:** Always provide something, never break
+- **Implementation:** Try discovery, catch all exceptions, use defaults
+
+**Q17: h-card parsing library - which one?**
+- **Answer:** Use mf2py (already in requirements for Micropub)
+- **Rationale:** Already a dependency, well-maintained
+- **Implementation:** `import mf2py; result = mf2py.parse(url=profile_url)`
+
+**Q18: Multiple h-cards on profile - which to use?**
+- **Answer:** First h-card with url property matching the profile URL
+- **Rationale:** Most specific match per IndieWeb convention
+- **Implementation:** Loop through h-cards, check url property
+
+**Q19: Discovery caching duration - how long?**
+- **Answer:** 24 hours, with manual refresh button in admin
+- **Rationale:** Balance between freshness and performance
+- **Implementation:** Store discovered_at timestamp, check age
+
+**Q20: Profile update mechanism - when to refresh?**
+- **Answer:** On login + manual refresh button + 24hr expiry
+- **Rationale:** Login is natural refresh point
+- **Implementation:** Call discovery in auth callback
+
+**Q21: Missing properties handling - what if no name/photo?**
+- **Answer:** name = domain from URL, photo = None (no image)
+- **Rationale:** Graceful degradation
+- **Implementation:** Use get() with defaults on parsed properties
+
+**Q22: Database schema for author_profile - exact columns?**
+- **Answer:** me_url (PK), name, photo, url, discovered_at, raw_data (JSON)
+- **Rationale:** Cache parsed data + raw for debugging
+- **Implementation:** Single row table, upsert on discovery
+
+## Microformats2 Answers
+
+**Q23: h-card placement - where exactly in templates?**
+- **Answer:** Only within h-entry author property (p-author h-card)
+- **Rationale:** Correct semantic placement per spec
+- **Implementation:** In note partial template, not standalone
+
+**Q24: h-feed container - which pages need it?**
+- **Answer:** Homepage (/) and any paginated list pages
+- **Rationale:** Feed pages only, not single note pages
+- **Implementation:** Wrap note list in div.h-feed with h1.p-name
+
+**Q25: Optional properties - which to include?**
+- **Answer:** Only what we have: author, name, url, published, content
+- **Rationale:** Don't add empty properties
+- **Implementation:** Use conditional template blocks
+
+**Q26: Micropub compatibility - any changes needed?**
+- **Answer:** No, Micropub already handles microformats correctly
+- **Rationale:** Micropub creates data, templates display it
+- **Implementation:** Ensure templates match Micropub's data model
+
+## Feed Integration Answers
+
+**Q27: RSS/Atom changes for media - how to include images?**
+- **Answer:** Add as enclosures (RSS) and link rel="enclosure" (Atom)
+- **Rationale:** Standard podcast/media pattern
+- **Implementation:** Loop through note.media, add enclosure elements
+
+**Q28: JSON Feed media handling - which property?**
+- **Answer:** Use "attachments" array per JSON Feed 1.1 spec
+- **Rationale:** Designed for exactly this use case
+- **Implementation:** Create attachment objects with url, mime_type
+
+**Q29: Feed caching - any changes needed?**
+- **Answer:** No, existing cache logic is sufficient
+- **Rationale:** Media URLs are stable once uploaded
+- **Implementation:** No changes required
+
+**Q30: Author in feeds - use discovered data?**
+- **Answer:** Yes, use discovered name and photo in feed metadata
+- **Rationale:** Consistency across all outputs
+- **Implementation:** Pass author_profile to feed templates
+
+## Database Migration Answers
+
+**Q31: Migration naming convention - what number?**
+- **Answer:** Use next sequential: 005_add_media_support.sql
+- **Rationale:** Continue existing pattern
+- **Implementation:** Check latest migration, increment
+
+**Q32: Migration rollback - needed?**
+- **Answer:** No, forward-only migrations per project convention
+- **Rationale:** Simplicity, follows existing pattern
+- **Implementation:** CREATE IF NOT EXISTS, never DROP
+
+**Q33: Migration testing - how to verify?**
+- **Answer:** Test on copy of production database
+- **Rationale:** Real-world data is best test
+- **Implementation:** Copy data/starpunk.db, run migration, verify
+
+## Testing Strategy Answers
+
+**Q34: Test data for media - what to use?**
+- **Answer:** Generate 1x1 pixel PNG in tests, don't use real files
+- **Rationale:** Minimal, fast, no binary files in repo
+- **Implementation:** Use Pillow to generate test images in memory
+
+**Q35: Author discovery mocking - how to test?**
+- **Answer:** Mock HTTP responses with test h-card HTML
+- **Rationale:** Deterministic, no external dependencies
+- **Implementation:** Use responses library or unittest.mock
+
+**Q36: Integration test priority - which are critical?**
+- **Answer:** Upload → Display → Edit → Delete flow
+- **Rationale:** Core user journey must work
+- **Implementation:** Single test that exercises full lifecycle
+
+## Error Handling Answers
+
+**Q37: Upload failure recovery - how to handle?**
+- **Answer:** Show error, preserve form data, allow retry
+- **Rationale:** Don't lose user's work
+- **Implementation:** Flash error, return to form with content preserved
+
+**Q38: Discovery network timeout - how long to wait?**
+- **Answer:** 5 second timeout for profile fetch
+- **Rationale:** Balance between patience and responsiveness
+- **Implementation:** Use requests timeout parameter
+
+## Deployment Answers
+
+**Q39: Media directory permissions - what's needed?**
+- **Answer:** data/media/ needs write permission for app user
+- **Rationale:** Same as existing data/ directory
+- **Implementation:** Document in deployment guide, create in setup
+
+**Q40: Upgrade path from v1.1.2 - any special steps?**
+- **Answer:** Run migration, create media directory, restart app
+- **Rationale:** Minimal disruption
+- **Implementation:** Add to CHANGELOG upgrade notes
+
+**Q41: Configuration changes - any new env vars?**
+- **Answer:** No, all settings have sensible defaults
+- **Rationale:** Maintain zero-config philosophy
+- **Implementation:** Hardcode limits in code with constants
+
+## Critical Path Decisions Summary
+
+These are the key decisions to unblock implementation:
+
+1. **Media upload flow**: Upload after note creation, associate via note_id
+2. **Author discovery**: Use mf2py, cache for 24hrs, graceful fallbacks
+3. **h-card parsing**: First h-card with matching URL property
+4. **h-card placement**: Only within h-entry as p-author
+5. **Migration strategy**: Sequential numbering (005), forward-only
+
+## Implementation Order
+
+Based on dependencies and complexity:
+
+### Phase 1: Custom Slugs (2 hours)
+- Simplest feature
+- No database changes
+- Template and validation only
+
+### Phase 2: Author Discovery (4 hours)
+- Build discovery module
+- Add author_profile table
+- Integrate with auth flow
+- Update templates
+
+### Phase 3: Media Upload (6 hours)
+- Most complex feature
+- Media table and migration
+- Upload handling
+- Template updates
+- Storage management
+
+## File Structure
+
+Key files to create/modify:
+
+### New Files
+- `starpunk/discovery.py` - Author discovery module
+- `starpunk/media.py` - Media handling module
+- `migrations/005_add_media_support.sql` - Database changes
+- `static/js/media-upload.js` - Optional enhancement
+
+### Modified Files
+- `templates/admin/new.html` - Add slug and media fields
+- `templates/admin/edit.html` - Add slug (readonly) and media
+- `templates/partials/note.html` - Add microformats markup
+- `templates/public/index.html` - Add h-feed container
+- `starpunk/routes/admin.py` - Handle slugs and uploads
+- `starpunk/routes/auth.py` - Trigger discovery on login
+- `starpunk/models/note.py` - Add media relationship
+
+## Success Metrics
+
+Implementation is complete when:
+
+1. ✅ Custom slug can be specified on creation
+2. ✅ Images can be uploaded and displayed
+3. ✅ Author info is discovered from IndieAuth profile
+4. ✅ IndieWebify.me validates h-feed and h-entry
+5. ✅ All tests pass
+6. ✅ No regressions in existing functionality
+7. ✅ Media files are tracked in database
+8. ✅ Errors are handled gracefully
+
+## Final Notes
+
+- Keep it simple - this is v1.2.0, not v2.0.0
+- Data preservation over premature optimization
+- When uncertain, choose the more explicit option
+- Document any deviations from this guidance
+
+---
+
+This Q&A document serves as the authoritative implementation guide for v1.2.0. Any questions not covered here should follow the principle of maximum simplicity.

+# v1.2.0 Feature Specification
+
+## Overview
+
+Version 1.2.0 focuses on three essential improvements to the StarPunk web interface:
+1. Custom slug support in the web UI
+2. Media upload capability (web UI only, not Micropub)
+3. Complete Microformats2 implementation
+
+## Feature 1: Custom Slugs in Web UI
+
+### Current State
+- Slugs are auto-generated from the first line of content
+- Custom slugs only possible via Micropub API (mp-slug property)
+- Web UI has no option to specify custom slugs
+
+### Requirements
+- Add optional "Slug" field to note creation form
+- Validate slug format (URL-safe, unique)
+- If empty, fall back to auto-generation
+- Support custom slugs in edit form as well
+
+### Design Specification
+
+#### Form Updates
+Location: `templates/admin/new.html` and `templates/admin/edit.html`
+
+Add new form field:
+```html
+<div class="form-group">
+  <label for="slug">Custom Slug (Optional)</label>
+  <input
+    type="text"
+    id="slug"
+    name="slug"
+    pattern="[a-z0-9-]+"
+    maxlength="200"
+    placeholder="leave-blank-for-auto-generation"
+    {% if editing %}readonly{% endif %}
+  >
+  <small>URL-safe characters only (lowercase letters, numbers, hyphens)</small>
+  {% if editing %}
+  <small class="text-warning">Slugs cannot be changed after creation to preserve permalinks</small>
+  {% endif %}
+</div>
+```
+
+#### Backend Changes
+Location: `starpunk/routes/admin.py`
+
+Modify `create_note_submit()`:
+- Extract slug from form data
+- Pass to `create_note()` as `custom_slug` parameter
+- Handle validation errors
+
+Modify `edit_note_submit()`:
+- Display current slug as read-only
+- Do NOT allow slug updates (prevent broken permalinks)
+
+#### Validation Rules
+- Must be URL-safe: `^[a-z0-9-]+$`
+- Maximum length: 200 characters
+- Must be unique (database constraint)
+- Empty string = auto-generate
+- **Read-only after creation** (no editing allowed)
+
+### Acceptance Criteria
+- [ ] Slug field appears in create note form
+- [ ] Slug field appears in edit note form
+- [ ] Custom slugs are validated for format
+- [ ] Custom slugs are validated for uniqueness
+- [ ] Empty field triggers auto-generation
+- [ ] Error messages are user-friendly
+
+---
+
+## Feature 2: Media Upload (Web UI Only)
+
+### Current State
+- No media upload capability
+- Notes are text/markdown only
+- No file storage infrastructure
+
+### Requirements
+- Upload images when creating/editing notes
+- Store uploaded files locally
+- Display media at top of note (social media style)
+- Support multiple media per note
+- Basic file validation
+- NOT implementing Micropub media endpoint (future version)
+
+### Design Specification
+
+#### Conceptual Model
+Media attachments work like social media posts (Twitter, Mastodon, etc.):
+- Media is displayed at the TOP of the note when published
+- Text content appears BELOW the media
+- Multiple images can be attached to a single note (maximum 4)
+- Media is stored as attachments, not inline markdown
+- Display order is upload order (no reordering interface)
+- Each image can have an optional caption for accessibility
+
+#### Storage Architecture
+```
+data/
+  media/
+    2025/
+      01/
+        image-slug-12345.jpg
+        another-image-67890.png
+```
+
+URL Structure: `/media/2025/01/filename.jpg` (date-organized paths)
+
+#### Database Schema
+
+**Option A: Junction Table (RECOMMENDED)**
+```sql
+-- Media files table
+CREATE TABLE media (
+    id INTEGER PRIMARY KEY,
+    filename TEXT NOT NULL,
+    original_name TEXT NOT NULL,
+    path TEXT NOT NULL UNIQUE,
+    mime_type TEXT NOT NULL,
+    size INTEGER NOT NULL,
+    width INTEGER,  -- Image dimensions for responsive display
+    height INTEGER,
+    uploaded_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Note-media relationship table
+CREATE TABLE note_media (
+    id INTEGER PRIMARY KEY,
+    note_id INTEGER NOT NULL,
+    media_id INTEGER NOT NULL,
+    display_order INTEGER NOT NULL DEFAULT 0,
+    caption TEXT,  -- Optional alt text/caption
+    created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    FOREIGN KEY (note_id) REFERENCES notes(id) ON DELETE CASCADE,
+    FOREIGN KEY (media_id) REFERENCES media(id) ON DELETE CASCADE,
+    UNIQUE(note_id, media_id)
+);
+
+CREATE INDEX idx_note_media_note ON note_media(note_id);
+CREATE INDEX idx_note_media_order ON note_media(note_id, display_order);
+```
+
+**Rationale**: Junction table provides flexibility for:
+- Multiple media per note with ordering
+- Reusing media across notes (future)
+- Per-attachment metadata (captions)
+- Efficient queries for syndication feeds
+
+#### Display Strategy
+
+**Note Rendering**:
+```html
+<article class="note">
+  <!-- Media displayed first -->
+  {% if note.media %}
+  <div class="media-attachments">
+    {% if note.media|length == 1 %}
+      <!-- Single image: full width -->
+      <img src="{{ media.url }}" alt="{{ media.caption or '' }}" class="single-image">
+    {% elif note.media|length == 2 %}
+      <!-- Two images: side by side -->
+      <div class="media-grid media-grid-2">
+        {% for media in note.media %}
+        <img src="{{ media.url }}" alt="{{ media.caption or '' }}">
+        {% endfor %}
+      </div>
+    {% else %}
+      <!-- 3-4 images: grid layout -->
+      <div class="media-grid media-grid-{{ note.media|length }}">
+        {% for media in note.media[:4] %}
+        <img src="{{ media.url }}" alt="{{ media.caption or '' }}">
+        {% endfor %}
+      </div>
+    {% endif %}
+  </div>
+  {% endif %}
+
+  <!-- Text content displayed below media -->
+  <div class="content">
+    {{ note.html|safe }}
+  </div>
+</article>
+```
+
+#### Upload Flow
+1. User selects multiple files via HTML file input
+2. Files validated (type, size)
+3. Files saved to `data/media/YYYY/MM/` with generated names
+4. Database records created in `media` table
+5. Associations created in `note_media` table
+6. Media displayed as thumbnails below textarea
+7. User can remove or reorder attachments
+
+#### Form Updates
+Location: `templates/admin/new.html` and `templates/admin/edit.html`
+
+```html
+<div class="form-group">
+  <label for="media">Attach Images</label>
+  <input
+    type="file"
+    id="media"
+    name="media"
+    accept="image/*"
+    multiple
+    class="media-upload"
+  >
+  <small>Accepted formats: JPG, PNG, GIF, WebP (max 10MB each, max 4 images)</small>
+
+  <!-- Preview attached media with captions -->
+  <div id="media-preview" class="media-preview">
+    <!-- Thumbnails appear here after upload with caption fields -->
+  </div>
+</div>
+
+<script>
+// Handle media as attachments, not inline insertion
+document.getElementById('media').addEventListener('change', async (e) => {
+  const preview = document.getElementById('media-preview');
+  const files = Array.from(e.target.files).slice(0, 4); // Max 4
+
+  for (const file of files) {
+    // Upload and show thumbnail
+    const url = await uploadMedia(file);
+    addMediaThumbnail(preview, url, file.name);
+  }
+});
+
+function addMediaThumbnail(container, url, filename) {
+  const thumb = document.createElement('div');
+  thumb.className = 'media-thumb';
+  thumb.innerHTML = `
+    <img src="${url}" alt="${filename}">
+    <input type="text" name="caption[]" placeholder="Caption (optional)" class="media-caption">
+    <button type="button" class="remove-media" data-url="${url}">×</button>
+    <input type="hidden" name="attached_media[]" value="${url}">
+  `;
+  container.appendChild(thumb);
+}
+</script>
+```
+
+#### Backend Implementation
+Location: New module `starpunk/media.py`
+
+Key functions:
+- `validate_media_file(file)` - Check type, size (max 10MB), dimensions (max 4096x4096)
+- `optimize_image(file)` - Resize if >2048px, correct EXIF orientation (using Pillow)
+- `save_media_file(file)` - Store optimized version to disk with date-based path
+- `generate_media_url(filename)` - Create public URL
+- `track_media_upload(metadata)` - Save to database
+- `attach_media_to_note(note_id, media_ids, captions)` - Create note-media associations with captions
+- `get_media_by_note(note_id)` - List media for a note ordered by display_order
+- `extract_image_dimensions(file)` - Get width/height for storage
+
+Image Processing with Pillow:
+```python
+from PIL import Image, ImageOps
+
+def optimize_image(file_obj):
+    """Optimize image for web display."""
+    img = Image.open(file_obj)
+
+    # Correct EXIF orientation
+    img = ImageOps.exif_transpose(img)
+
+    # Check dimensions
+    if max(img.size) > 4096:
+        raise ValueError("Image dimensions exceed 4096x4096")
+
+    # Resize if needed (preserve aspect ratio)
+    if max(img.size) > 2048:
+        img.thumbnail((2048, 2048), Image.Resampling.LANCZOS)
+
+    return img
+```
+
+#### Routes
+Location: `starpunk/routes/public.py`
+
+Add route to serve media:
+```python
+@bp.route('/media/<year>/<month>/<filename>')
+def serve_media(year, month, filename):
+    # Serve file from data/media/YYYY/MM/
+    # Set appropriate cache headers
+```
+
+Location: `starpunk/routes/admin.py`
+
+Add upload endpoint:
+```python
+@bp.route('/admin/upload', methods=['POST'])
+@require_auth
+def upload_media():
+    # Handle AJAX upload, return JSON with URL and media_id
+    # Store in media table, return metadata
+```
+
+#### Syndication Feed Support
+
+**RSS 2.0 Strategy**:
+```xml
+<!-- Embed media as HTML in description with CDATA -->
+<item>
+  <title>Note Title</title>
+  <description><![CDATA[
+    <div class="media">
+      <img src="https://site.com/media/2025/01/image1.jpg" />
+      <img src="https://site.com/media/2025/01/image2.jpg" />
+    </div>
+    <div class="content">
+      <p>Note text content here...</p>
+    </div>
+  ]]></description>
+  <pubDate>...</pubDate>
+</item>
+```
+Rationale: RSS `<enclosure>` only supports single items and is meant for podcasts/downloads. HTML in description is standard for blog posts with images.
+
+**ATOM 1.0 Strategy**:
+```xml
+<!-- Multiple link elements with rel="enclosure" for each media item -->
+<entry>
+  <title>Note Title</title>
+  <link rel="enclosure"
+        type="image/jpeg"
+        href="https://site.com/media/2025/01/image1.jpg"
+        length="123456" />
+  <link rel="enclosure"
+        type="image/jpeg"
+        href="https://site.com/media/2025/01/image2.jpg"
+        length="234567" />
+  <content type="html">
+    &lt;div class="media"&gt;
+      &lt;img src="https://site.com/media/2025/01/image1.jpg" /&gt;
+      &lt;img src="https://site.com/media/2025/01/image2.jpg" /&gt;
+    &lt;/div&gt;
+    &lt;div&gt;Note text content...&lt;/div&gt;
+  </content>
+</entry>
+```
+Rationale: ATOM supports multiple `<link rel="enclosure">` elements. We include both enclosures (for feed readers that understand them) AND HTML content (for universal display).
+
+**JSON Feed 1.1 Strategy**:
+```json
+{
+  "id": "...",
+  "title": "Note Title",
+  "content_html": "<div class='media'>...</div><div>Note text...</div>",
+  "attachments": [
+    {
+      "url": "https://site.com/media/2025/01/image1.jpg",
+      "mime_type": "image/jpeg",
+      "size_in_bytes": 123456
+    },
+    {
+      "url": "https://site.com/media/2025/01/image2.jpg",
+      "mime_type": "image/jpeg",
+      "size_in_bytes": 234567
+    }
+  ]
+}
+```
+Rationale: JSON Feed has native support for multiple attachments! This is the cleanest implementation.
+
+**Feed Generation Updates**:
+- Modify `generate_rss()` to prepend media HTML to content
+- Modify `generate_atom()` to add `<link rel="enclosure">` elements
+- Modify `generate_json_feed()` to populate `attachments` array
+- Query `note_media` JOIN `media` when generating feeds
+
+#### Security Considerations
+- Validate MIME types server-side (JPEG, PNG, GIF, WebP only)
+- Reject files over 10MB (before processing)
+- Limit total uploads (4 images max per note)
+- Sanitize filenames (remove special characters, use slugify)
+- Prevent directory traversal attacks
+- Add rate limiting to upload endpoint
+- Validate image dimensions (max 4096x4096, reject if larger)
+- Use Pillow to verify file integrity (corrupted files will fail to open)
+- Resize images over 2048px to prevent memory issues
+- Strip potentially harmful EXIF data during optimization
+
+### Acceptance Criteria
+- [ ] Multiple file upload field in create/edit forms
+- [ ] Images saved to data/media/ directory after optimization
+- [ ] Media-note associations tracked in database with captions
+- [ ] Media displayed at TOP of notes
+- [ ] Text content displayed BELOW media
+- [ ] Media served at /media/YYYY/MM/filename
+- [ ] File type validation (JPEG, PNG, GIF, WebP only)
+- [ ] File size validation (10MB max, checked before processing)
+- [ ] Image dimension validation (4096x4096 max)
+- [ ] Automatic resize for images over 2048px
+- [ ] EXIF orientation correction during processing
+- [ ] Max 4 images per note enforced
+- [ ] Caption field for each uploaded image
+- [ ] Captions used as alt text in HTML
+- [ ] Media appears in RSS feeds (HTML in description)
+- [ ] Media appears in ATOM feeds (enclosures + HTML)
+- [ ] Media appears in JSON feeds (attachments array)
+- [ ] User can remove attached images
+- [ ] Display order matches upload order (no reordering UI)
+- [ ] Error handling for invalid/oversized/corrupted files
+

+
+## Feature 3: Complete Microformats2 Support
+
+### Current State
+- Basic h-entry on note pages
+- Basic h-feed on index
+- Missing h-card (author info)
+- Missing many microformats properties
+- No rel=me links
+
+### Requirements
+Full compliance with Microformats2 specification:
+- Complete h-entry implementation
+- Author h-card on all pages
+- Proper h-feed structure
+- rel=me for identity verification
+- All relevant properties marked up
+
+### Design Specification
+
+#### Author Discovery System
+When a user authenticates via IndieAuth, we discover their author information from their profile URL:
+
+1. **Discovery Process** (runs during login):
+   - User logs in with IndieAuth using their domain (e.g., https://user.example.com)
+   - System fetches the user's profile page
+   - Parses h-card microformats from the profile
+   - Extracts: name, photo, bio/note, rel-me links
+   - Caches author info in database (new `author_profile` table)
+
+2. **Database Schema** for Author Profile:
+```sql
+CREATE TABLE author_profile (
+    id INTEGER PRIMARY KEY,
+    me_url TEXT NOT NULL UNIQUE,  -- The IndieAuth 'me' URL
+    name TEXT,                     -- From h-card p-name
+    photo TEXT,                    -- From h-card u-photo
+    bio TEXT,                      -- From h-card p-note
+    rel_me_links TEXT,             -- JSON array of rel-me URLs
+    discovered_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+3. **Caching Strategy**:
+   - Cache on first login
+   - Refresh on each login (but use cache if discovery fails)
+   - Manual refresh button in admin settings
+   - Cache expires after 7 days (configurable)
+
+4. **Fallback Behavior**:
+   - If discovery fails, use cached data if available
+   - If no cache and discovery fails, use minimal defaults:
+     - Name: Domain name (e.g., "user.example.com")
+     - Photo: None (gracefully degrade)
+     - Bio: None
+   - Log discovery failures for debugging
+
+#### h-card (Author Information)
+Location: `templates/partials/author.html` (new)
+
+Required properties from discovered profile:
+- p-name (author name from discovery)
+- u-url (author URL from ADMIN_ME)
+- u-photo (avatar from discovery, optional)
+
+```html
+<div class="h-card">
+  <a class="p-name u-url" href="{{ author.me_url }}">
+    {{ author.name or author.me_url }}
+  </a>
+  {% if author.photo %}
+  <img class="u-photo" src="{{ author.photo }}" alt="{{ author.name }}">
+  {% endif %}
+  {% if author.bio %}
+  <p class="p-note">{{ author.bio }}</p>
+  {% endif %}
+</div>
+```
+
+#### Enhanced h-entry
+Location: `templates/note.html`
+
+Complete properties with discovered author and media support:
+- p-name (note title, if exists)
+- e-content (note content)
+- dt-published (creation date)
+- dt-updated (modification date)
+- u-url (permalink)
+- p-author (nested h-card with discovered info)
+- u-uid (unique identifier)
+- u-photo (multiple for multi-photo posts)
+- p-category (tags, future)
+
+```html
+<article class="h-entry">
+  <!-- Multiple u-photo for multi-photo posts (social media style) -->
+  {% if note.media %}
+    {% for media in note.media %}
+    <img class="u-photo" src="{{ media.url }}" alt="{{ media.caption or '' }}">
+    {% endfor %}
+  {% endif %}
+
+  <!-- Text content -->
+  <div class="e-content">
+    {{ note.html|safe }}
+  </div>
+
+  <!-- Title only if exists (most notes won't have titles) -->
+  {% if note.has_explicit_title %}
+  <h1 class="p-name">{{ note.title }}</h1>
+  {% endif %}
+
+  <footer>
+    <a class="u-url u-uid" href="{{ url }}">
+      <time class="dt-published" datetime="{{ iso_date }}">
+        {{ formatted_date }}
+      </time>
+    </a>
+
+    {% if note.updated_at %}
+    <time class="dt-updated" datetime="{{ updated_iso }}">
+      Updated: {{ updated_formatted }}
+    </time>
+    {% endif %}
+
+    <!-- Author h-card only within h-entry -->
+    <div class="p-author h-card">
+      <a class="p-name u-url" href="{{ author.me_url }}">
+        {{ author.name or author.me_url }}
+      </a>
+      {% if author.photo %}
+      <img class="u-photo" src="{{ author.photo }}" alt="{{ author.name }}">
+      {% endif %}
+    </div>
+  </footer>
+</article>
+```
+
+**Multi-photo Implementation Notes**:
+- Multiple `u-photo` elements indicate a multi-photo post (like Instagram, Twitter)
+- Photos are considered primary content when present
+- Consuming applications (like Bridgy) will respect platform limits (e.g., Twitter's 4-photo max)
+- Photos appear BEFORE text content, matching social media conventions
+
+#### Enhanced h-feed
+Location: `templates/index.html`
+
+Required structure:
+- h-feed container
+- p-name (feed title)
+- p-author (feed author)
+- Multiple h-entry children
+
+#### rel=me Links
+Location: `templates/base.html`
+
+Add to <head> using discovered rel-me links:
+```html
+{% if author.rel_me_links %}
+  {% for profile in author.rel_me_links %}
+  <link rel="me" href="{{ profile }}">
+  {% endfor %}
+{% endif %}
+```
+
+#### Discovery Module
+Location: New module `starpunk/author_discovery.py`
+
+Key functions:
+- `discover_author_info(me_url)` - Fetch and parse h-card from profile
+- `parse_hcard(html, url)` - Extract h-card properties
+- `parse_rel_me(html, url)` - Extract rel-me links
+- `cache_author_profile(profile_data)` - Store in database
+- `get_cached_author(me_url)` - Retrieve from cache
+- `refresh_author_profile(me_url)` - Force refresh
+
+Integration points:
+- Called during IndieAuth login success in `auth_external.py`
+- Admin settings page for manual refresh (`/admin/settings`)
+- Template context processor to inject author data globally
+
+#### Microformats Parsing
+Use existing library for parsing:
+- Option 1: `mf2py` - Python microformats2 parser
+- Option 2: Custom minimal parser (lighter weight)
+
+Parse these specific properties:
+- h-card properties: name, photo, url, note, email
+- rel-me links for identity verification
+- Store as JSON in database for flexibility
+
+### Testing & Validation
+
+Use these tools to validate:
+1. https://indiewebify.me/ - Complete IndieWeb validation
+2. https://microformats.io/ - Microformats parser
+3. https://search.google.com/test/rich-results - Google's structured data test
+
+### Acceptance Criteria
+- [ ] Author info discovered from IndieAuth profile URL
+- [ ] h-card present within h-entries only (not standalone)
+- [ ] h-entry has all required properties
+- [ ] h-feed properly structures the homepage
+- [ ] rel=me links in HTML head (from discovery)
+- [ ] Passes indiewebify.me Level 2 tests
+- [ ] Parsed correctly by microformats.io
+- [ ] Graceful fallback when discovery fails
+- [ ] Author profile cached in database
+- [ ] Manual refresh option in admin
+
+---
+
+## Implementation Order
+
+Recommended implementation sequence:
+
+1. **Custom Slugs** (simplest, least dependencies)
+   - Modify forms
+   - Update backend
+   - Test uniqueness
+
+2. **Microformats2** (template-only changes)
+   - Add h-card partial
+   - Enhance h-entry
+   - Add rel=me links
+   - Validate with tools
+
+3. **Media Upload** (most complex)
+   - Create media module
+   - Add upload forms
+   - Implement storage
+   - Add serving route
+
+---
+
+## Out of Scope
+
+The following are explicitly NOT included in v1.2.0:
+
+- Micropub media endpoint
+- Video upload support
+- Thumbnail generation (separate from main image)
+- CDN integration
+- Media gallery interface
+- Webmention support
+- Multi-user support
+- Self-hosted IndieAuth (see ADR-056)
+
+---
+
+## Database Schema Changes
+
+Required schema changes for v1.2.0:
+
+### 1. Media Tables
+```sql
+-- Media files table
+CREATE TABLE media (
+    id INTEGER PRIMARY KEY,
+    filename TEXT NOT NULL,
+    original_name TEXT NOT NULL,
+    path TEXT NOT NULL UNIQUE,
+    mime_type TEXT NOT NULL,
+    size INTEGER NOT NULL,
+    width INTEGER,  -- Image dimensions
+    height INTEGER,
+    uploaded_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Note-media relationship table
+CREATE TABLE note_media (
+    id INTEGER PRIMARY KEY,
+    note_id INTEGER NOT NULL,
+    media_id INTEGER NOT NULL,
+    display_order INTEGER NOT NULL DEFAULT 0,
+    caption TEXT,  -- Optional alt text/caption
+    created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    FOREIGN KEY (note_id) REFERENCES notes(id) ON DELETE CASCADE,
+    FOREIGN KEY (media_id) REFERENCES media(id) ON DELETE CASCADE,
+    UNIQUE(note_id, media_id)
+);
+
+CREATE INDEX idx_note_media_note ON note_media(note_id);
+CREATE INDEX idx_note_media_order ON note_media(note_id, display_order);
+```
+
+### 2. Author Profile Table
+```sql
+CREATE TABLE author_profile (
+    id INTEGER PRIMARY KEY,
+    me_url TEXT NOT NULL UNIQUE,
+    name TEXT,
+    photo TEXT,
+    bio TEXT,
+    rel_me_links TEXT,  -- JSON array
+    discovered_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+### 3. No Changes Required For:
+- Custom slugs: Already supported via existing `slug` column
+
+---
+
+## Configuration Changes
+
+New configuration variables:
+```
+# Media settings
+MAX_UPLOAD_SIZE=10485760  # 10MB in bytes
+ALLOWED_MEDIA_TYPES=image/jpeg,image/png,image/gif,image/webp
+MEDIA_PATH=data/media  # Storage location
+
+# Author discovery settings
+AUTHOR_CACHE_TTL=604800  # 7 days in seconds
+AUTHOR_DISCOVERY_TIMEOUT=5.0  # HTTP timeout for profile fetch
+```
+
+Note: Author information is NOT configured via environment variables. It is discovered from the authenticated user's IndieAuth profile URL.
+
+---
+
+## Security Considerations
+
+1. **File Upload Security**
+   - Validate MIME types
+   - Check file extensions
+   - Limit file sizes
+   - Sanitize filenames
+   - Store outside web root if possible
+
+2. **Slug Validation**
+   - Prevent directory traversal
+   - Enforce URL-safe characters
+   - Check uniqueness
+
+3. **Microformats**
+   - No security implications
+   - Ensure proper HTML escaping continues
+
+---
+
+## Testing Requirements
+
+### Unit Tests
+- Slug validation logic
+- Media file validation
+- Unique filename generation
+
+### Integration Tests
+- Custom slug creation flow
+- Media upload and serving
+- Microformats parsing
+
+### Manual Testing
+- Upload various image formats
+- Try invalid slugs
+- Validate microformats output
+- Test with screen readers
+
+---
+
+## Additional Design Considerations
+
+### Media Upload Details
+1. **Social Media Model**: Media works like Twitter/Mastodon posts
+   - Media displays at TOP of note
+   - Text appears BELOW media
+   - Multiple images supported (max 4)
+   - No inline markdown images (attachments only)
+   - Display order is upload order (no reordering)
+
+2. **File Type Restrictions**:
+   - Accept: image/jpeg, image/png, image/gif, image/webp
+   - Reject: SVG (security), video formats (v1.2.0 scope)
+   - Validate MIME type server-side, not just extension
+
+3. **Image Processing** (using Pillow):
+   - Automatic resize if >2048px (longest edge)
+   - EXIF orientation correction
+   - File integrity validation
+   - Preserve aspect ratio
+   - Quality setting: 95 (high quality)
+   - No separate thumbnail generation
+
+4. **Display Layout**:
+   - 1 image: Full width
+   - 2 images: Side by side (50% each)
+   - 3 images: Grid (1 large + 2 small, or equal grid)
+   - 4 images: 2x2 grid
+
+5. **Image Limits** (per ADR-058):
+   - Max file size: 10MB per image
+   - Max dimensions: 4096x4096 pixels
+   - Auto-resize threshold: 2048 pixels (longest edge)
+   - Max images per note: 4
+
+6. **Accessibility Features**:
+   - Optional caption field for each image
+   - Captions stored in `note_media.caption`
+   - Used as alt text in HTML output
+   - Included in syndication feeds
+
+7. **Database Design Rationale**:
+   - Junction table allows flexible ordering
+   - Supports future media reuse across notes
+   - Per-attachment captions for accessibility
+   - Efficient queries for feed generation
+
+8. **Feed Syndication Strategy**:
+   - RSS: HTML with images in description (universal support)
+   - ATOM: Both enclosures AND HTML content (best compatibility)
+   - JSON Feed: Native attachments array (cleanest implementation)
+
+### Slug Handling
+1. **Absolute No-Edit Policy**: Once created, slugs are immutable
+   - No admin override
+   - No database updates allowed
+   - Prevents broken permalinks completely
+
+2. **Validation Pattern**: `^[a-z0-9-]+$`
+   - Lowercase only for consistency
+   - No underscores (hyphens preferred)
+   - No special characters
+
+### Author Discovery Edge Cases
+1. **Multiple h-cards on Profile**:
+   - Use first representative h-card (class="h-card" on body or first found)
+   - Log if multiple found for debugging
+
+2. **Missing Properties**:
+   - Name: Falls back to domain
+   - Photo: Omit if not found
+   - Bio: Omit if not found
+   - All properties are optional except URL
+
+3. **Network Failures**:
+   - Use cached data even if expired
+   - Log failure for monitoring
+   - Never block login due to discovery failure
+
+4. **Invalid Markup**:
+   - Best-effort parsing
+   - Log parsing errors
+   - Use whatever can be extracted
+
+## Success Metrics
+
+v1.2.0 is successful when:
+1. Users can specify custom slugs via web UI (immutable after creation)
+2. Users can upload images via web UI with auto-insertion
+3. Author info discovered from IndieAuth profile
+4. Site passes IndieWebify.me Level 2
+5. All existing tests continue to pass
+6. No regression in existing functionality
+7. Media tracked in database with metadata
+8. Graceful handling of discovery failures

+# Media Upload Implementation Guide
+
+## Overview
+This guide provides implementation details for the v1.2.0 media upload feature based on the finalized design.
+
+## Key Design Decisions
+
+### Image Limits (per ADR-058)
+- **Max file size**: 10MB per image (reject before processing)
+- **Max dimensions**: 4096x4096 pixels (reject if larger)
+- **Auto-resize threshold**: 2048 pixels on longest edge
+- **Max images per note**: 4
+- **Accepted formats**: JPEG, PNG, GIF, WebP only
+
+### Features
+- **Caption support**: Each image has optional caption field
+- **No reordering**: Display order matches upload order
+- **Auto-optimization**: Images >2048px automatically resized
+- **EXIF correction**: Orientation fixed during processing
+
+## Implementation Approach
+
+### 1. Dependencies
+Add to `pyproject.toml`:
+```toml
+dependencies = [
+    # ... existing dependencies
+    "Pillow>=10.0.0",  # Image processing
+]
+```
+
+### 2. Image Processing Module Structure
+Create `starpunk/media.py`:
+
+```python
+from PIL import Image, ImageOps
+import hashlib
+import os
+from pathlib import Path
+from datetime import datetime
+
+class MediaProcessor:
+    MAX_FILE_SIZE = 10 * 1024 * 1024  # 10MB
+    MAX_DIMENSIONS = 4096
+    RESIZE_THRESHOLD = 2048
+    ALLOWED_MIMES = {
+        'image/jpeg': '.jpg',
+        'image/png': '.png',
+        'image/gif': '.gif',
+        'image/webp': '.webp'
+    }
+
+    def validate_file_size(self, file_obj):
+        """Check file size before processing."""
+        file_obj.seek(0, os.SEEK_END)
+        size = file_obj.tell()
+        file_obj.seek(0)
+
+        if size > self.MAX_FILE_SIZE:
+            raise ValueError(f"File too large: {size} bytes (max {self.MAX_FILE_SIZE})")
+
+        return size
+
+    def optimize_image(self, file_obj):
+        """Optimize image for web display."""
+        # Open and validate
+        try:
+            img = Image.open(file_obj)
+        except Exception as e:
+            raise ValueError(f"Invalid or corrupted image: {e}")
+
+        # Correct EXIF orientation
+        img = ImageOps.exif_transpose(img)
+
+        # Check dimensions
+        width, height = img.size
+        if max(width, height) > self.MAX_DIMENSIONS:
+            raise ValueError(f"Image too large: {width}x{height} (max {self.MAX_DIMENSIONS})")
+
+        # Resize if needed
+        if max(width, height) > self.RESIZE_THRESHOLD:
+            img.thumbnail((self.RESIZE_THRESHOLD, self.RESIZE_THRESHOLD),
+                         Image.Resampling.LANCZOS)
+
+        return img
+
+    def generate_filename(self, original_name, content):
+        """Generate unique filename with date path."""
+        # Create hash for uniqueness
+        hash_obj = hashlib.sha256(content)
+        hash_hex = hash_obj.hexdigest()[:8]
+
+        # Get extension
+        _, ext = os.path.splitext(original_name)
+
+        # Generate date-based path
+        now = datetime.now()
+        year = now.strftime('%Y')
+        month = now.strftime('%m')
+
+        # Create filename
+        filename = f"{now.strftime('%Y%m%d')}-{hash_hex}{ext}"
+
+        return f"{year}/{month}/{filename}"
+```
+
+### 3. Database Migration
+Create migration for media tables:
+
+```sql
+-- Create media table
+CREATE TABLE IF NOT EXISTS media (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    filename TEXT NOT NULL,
+    original_name TEXT NOT NULL,
+    path TEXT NOT NULL UNIQUE,
+    mime_type TEXT NOT NULL,
+    size INTEGER NOT NULL,
+    width INTEGER,
+    height INTEGER,
+    uploaded_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Create note_media junction table with caption support
+CREATE TABLE IF NOT EXISTS note_media (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    note_id INTEGER NOT NULL,
+    media_id INTEGER NOT NULL,
+    display_order INTEGER NOT NULL DEFAULT 0,
+    caption TEXT,  -- Optional caption for accessibility
+    created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    FOREIGN KEY (note_id) REFERENCES notes(id) ON DELETE CASCADE,
+    FOREIGN KEY (media_id) REFERENCES media(id) ON DELETE CASCADE,
+    UNIQUE(note_id, media_id)
+);
+
+-- Create indexes
+CREATE INDEX idx_note_media_note ON note_media(note_id);
+CREATE INDEX idx_note_media_order ON note_media(note_id, display_order);
+```
+
+### 4. Upload Endpoint
+In `starpunk/routes/admin.py`:
+
+```python
+@bp.route('/admin/upload', methods=['POST'])
+@require_auth
+def upload_media():
+    """Handle AJAX media upload."""
+    if 'file' not in request.files:
+        return jsonify({'error': 'No file provided'}), 400
+
+    file = request.files['file']
+
+    try:
+        # Process with MediaProcessor
+        processor = MediaProcessor()
+
+        # Validate size first (before loading image)
+        size = processor.validate_file_size(file.file)
+
+        # Optimize image
+        optimized = processor.optimize_image(file.file)
+
+        # Generate path
+        path = processor.generate_filename(file.filename, file.read())
+
+        # Save to disk
+        save_path = Path(app.config['MEDIA_PATH']) / path
+        save_path.parent.mkdir(parents=True, exist_ok=True)
+        optimized.save(save_path, quality=95, optimize=True)
+
+        # Save to database
+        media_id = save_media_metadata(
+            filename=path.name,
+            original_name=file.filename,
+            path=path,
+            mime_type=file.content_type,
+            size=save_path.stat().st_size,
+            width=optimized.width,
+            height=optimized.height
+        )
+
+        # Return success
+        return jsonify({
+            'success': True,
+            'media_id': media_id,
+            'url': f'/media/{path}'
+        })
+
+    except ValueError as e:
+        return jsonify({'error': str(e)}), 400
+    except Exception as e:
+        app.logger.error(f"Upload failed: {e}")
+        return jsonify({'error': 'Upload failed'}), 500
+```
+
+### 5. Template Updates
+Update note creation/edit forms to include:
+- Multiple file input with accept attribute
+- Caption fields for each uploaded image
+- Client-side preview with caption inputs
+- Remove button for each image
+- Hidden fields to track attached media IDs
+
+### 6. Display Implementation
+When rendering notes:
+1. Query `note_media` JOIN `media` ordered by `display_order`
+2. Display images at top of note
+3. Use captions as alt text
+4. Apply responsive grid layout CSS
+
+## Testing Checklist
+
+### Unit Tests
+- [ ] File size validation (reject >10MB)
+- [ ] Dimension validation (reject >4096px)
+- [ ] MIME type validation (accept only JPEG/PNG/GIF/WebP)
+- [ ] Image resize logic (>2048px gets resized)
+- [ ] Filename generation (unique, date-based)
+- [ ] EXIF orientation correction
+
+### Integration Tests
+- [ ] Upload single image
+- [ ] Upload multiple images (up to 4)
+- [ ] Reject 5th image
+- [ ] Upload with captions
+- [ ] Delete uploaded image
+- [ ] Edit note with existing media
+- [ ] Corrupted file handling
+- [ ] Oversized file handling
+
+### Manual Testing
+- [ ] Upload from phone camera
+- [ ] Upload screenshots
+- [ ] Test all supported formats
+- [ ] Verify captions appear as alt text
+- [ ] Check responsive layouts (1-4 images)
+- [ ] Verify images in RSS/ATOM/JSON feeds
+
+## Error Messages
+Provide clear, actionable error messages:
+
+- "File too large. Maximum size is 10MB"
+- "Image dimensions too large. Maximum is 4096x4096 pixels"
+- "Invalid image format. Accepted: JPEG, PNG, GIF, WebP"
+- "Maximum 4 images per note"
+- "Image appears to be corrupted"
+
+## Performance Considerations
+- Process images synchronously (single-user CMS)
+- Use quality=95 for good balance of size/quality
+- Consider lazy loading for feed pages
+- Cache resized images (future enhancement)
+
+## Security Notes
+- Always validate MIME type server-side
+- Use Pillow to verify file integrity
+- Sanitize filenames before saving
+- Prevent directory traversal in media paths
+- Strip EXIF data that might contain GPS/personal info
+
+## Future Enhancements (NOT in v1.2.0)
+- Micropub media endpoint support
+- Video upload support
+- Separate thumbnail generation
+- CDN integration
+- Bulk upload interface
+- Image editing tools (crop, rotate)

+4. **Captions**: Yes, optional caption field for each image
+
+## Architectural Decisions
+
+### ADR-057: Media Attachment Model
+- Social media style attachments (not inline markdown)
+- Media displays at TOP of notes
+- Text content appears BELOW media
+- Junction table for flexible associations
+
+### ADR-058: Image Optimization Strategy
+- **Max file size**: 10MB per image
+- **Max dimensions**: 4096x4096 pixels
+- **Auto-resize**: Images >2048px resized automatically
+- **Processing library**: Pillow
+- **Formats**: JPEG, PNG, GIF, WebP only
+
+## Technical Specifications
+
+### Image Processing
+- **Validation**: Size, dimensions, format, integrity
+- **Optimization**: Resize to 2048px max, EXIF correction
+- **Quality**: 95% JPEG quality (high quality)
+- **Storage**: data/media/YYYY/MM/ structure
+
+### Database Schema
+```sql
+-- Media table with dimensions
+CREATE TABLE media (
+    id INTEGER PRIMARY KEY,
+    filename TEXT NOT NULL,
+    original_name TEXT NOT NULL,
+    path TEXT NOT NULL UNIQUE,
+    mime_type TEXT NOT NULL,
+    size INTEGER NOT NULL,
+    width INTEGER,
+    height INTEGER,
+    uploaded_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Junction table with captions
+CREATE TABLE note_media (
+    id INTEGER PRIMARY KEY,
+    note_id INTEGER NOT NULL,
+    media_id INTEGER NOT NULL,
+    display_order INTEGER NOT NULL DEFAULT 0,
+    caption TEXT,  -- For accessibility
+    created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    FOREIGN KEY (note_id) REFERENCES notes(id) ON DELETE CASCADE,
+    FOREIGN KEY (media_id) REFERENCES media(id) ON DELETE CASCADE,
+    UNIQUE(note_id, media_id)
+);
+```
+
+### User Interface
+- Multiple file input (accept images only)
+- Caption field for each uploaded image
+- Preview thumbnails during upload
+- Remove button per image
+- No drag-and-drop reordering
+- Maximum 4 images enforced
+

+## Prerequisites
+
+Before upgrading:
+
+1. **Backup your data**:
+   ```bash
+   # Backup database
+   cp data/starpunk.db data/starpunk.db.backup
+
+   # Backup notes
+   cp -r data/notes data/notes.backup
+   ```
+
+2. **Check current version**:
+   ```bash
+   uv run python -c "import starpunk; print(starpunk.__version__)"
+   ```
+
+3. **Review changelog**: Read `CHANGELOG.md` for detailed changes
+
+## Upgrade Steps
+
+### Step 1: Stop StarPunk
+
+If running in production:
+
+```bash
+# For systemd service
+sudo systemctl stop starpunk
+
+# For container deployment
+podman stop starpunk  # or docker stop starpunk
+```
+
+### Step 2: Pull Latest Code
+
+```bash
+# From git repository
+git fetch origin
+git checkout v1.1.2-rc.1
+
+# Or download release tarball
+wget https://github.com/YOUR_USERNAME/starpunk/archive/v1.1.2-rc.1.tar.gz
+tar xzf v1.1.2-rc.1.tar.gz
+cd starpunk-1.1.2-rc.1
+```
+
+### Step 3: Update Dependencies
+
+```bash
+# Update Python dependencies with uv
+uv sync
+```
+
+**Note**: v1.1.2 requires `psutil` for memory monitoring. This will be installed automatically.
+
+### Step 4: Verify Configuration
+
+No new required configuration variables in v1.1.2, but you can optionally configure new features:
+
+```bash
+# Optional: Disable metrics (default: enabled)
+export METRICS_ENABLED=true
+
+# Optional: Configure metrics sampling rates
+export METRICS_SAMPLING_DATABASE=1.0    # 100% of database operations
+export METRICS_SAMPLING_HTTP=0.1        # 10% of HTTP requests
+export METRICS_SAMPLING_RENDER=0.1      # 10% of template renders
+
+# Optional: Configure memory monitoring interval (default: 30 seconds)
+export METRICS_MEMORY_INTERVAL=30
+
+# Optional: Disable feed caching (default: enabled)
+export FEED_CACHE_ENABLED=true
+
+# Optional: Configure feed cache size (default: 50 entries)
+export FEED_CACHE_MAX_SIZE=50
+
+# Optional: Configure feed cache TTL (default: 300 seconds / 5 minutes)
+export FEED_CACHE_SECONDS=300
+```
+
+### Step 5: Run Database Migrations
+
+StarPunk uses automatic migrations - no manual SQL needed:
+
+```bash
+# Migrations run automatically on startup
+# No database schema changes in v1.1.2
+uv run python -c "from starpunk import create_app; app = create_app(); print('Database ready')"
+```
+
+### Step 6: Restart StarPunk
+
+```bash
+# For systemd service
+sudo systemctl start starpunk
+sudo systemctl status starpunk
+
+# For container deployment
+podman start starpunk  # or docker start starpunk
+
+# For development
+uv run flask run
+```
+
+### Step 7: Verify Upgrade
+
+1. **Check version**:
+   ```bash
+   uv run python -c "import starpunk; print(starpunk.__version__)"
+   # Should output: 1.1.2-rc.1
+   ```
+
+2. **Test health endpoint**:
+   ```bash
+   curl http://localhost:5000/health
+   # Should return: {"status":"ok","version":"1.1.2-rc.1"}
+   ```
+
+3. **Test feed endpoints**:
+   ```bash
+   # RSS feed
+   curl http://localhost:5000/feed.rss
+
+   # ATOM feed
+   curl http://localhost:5000/feed.atom
+
+   # JSON Feed
+   curl http://localhost:5000/feed.json
+
+   # Content negotiation
+   curl -H "Accept: application/atom+xml" http://localhost:5000/feed
+
+   # OPML export
+   curl http://localhost:5000/opml.xml
+   ```
+
+4. **Check metrics dashboard** (requires authentication):
+   ```bash
+   # Visit http://localhost:5000/admin/metrics-dashboard
+   # Should show feed statistics section
+   ```
+
+5. **Run test suite** (optional):
+   ```bash
+   uv run pytest
+   # Should show: 766 tests passing
+   ```
+
+## New Features and Endpoints
+
+### Multi-Format Feed Endpoints
+
+- **`/feed`** - Content negotiation endpoint (respects Accept header)
+- **`/feed.rss`** or **`/feed.xml`** - Explicit RSS 2.0 feed
+- **`/feed.atom`** - Explicit ATOM 1.0 feed
+- **`/feed.json`** - Explicit JSON Feed 1.1
+- **`/opml.xml`** - OPML 2.0 subscription list
+
+### Content Negotiation
+
+The `/feed` endpoint now supports HTTP content negotiation:
+
+```bash
+# Request ATOM feed
+curl -H "Accept: application/atom+xml" http://localhost:5000/feed
+
+# Request JSON Feed
+curl -H "Accept: application/json" http://localhost:5000/feed
+
+# Request RSS feed (default)
+curl -H "Accept: */*" http://localhost:5000/feed
+```
+
+### Feed Caching
+
+All feed endpoints now support:
+- **ETag headers** for conditional requests
+- **304 Not Modified** responses for unchanged content
+- **LRU cache** with 5-minute TTL (configurable)
+- **Cache statistics** on admin dashboard
+
+Example:
+```bash
+# First request - generates feed and returns ETag
+curl -i http://localhost:5000/feed.rss
+# Response: ETag: W/"abc123..."
+

+- **JSON streaming**: Line-by-line JSON generation
+- **Generation time**: 2-5ms for 50 items
+
+### Caching Benefits
+- **Bandwidth savings**: 304 responses for repeat requests
+- **Cache overhead**: <1ms per request
+- **Memory bounded**: LRU cache limited to 50 entries
+- **TTL**: 5-minute cache lifetime (configurable)
+
+### Metrics Overhead
+- **Database monitoring**: Negligible overhead with connection pooling
+- **HTTP metrics**: 10% sampling (configurable)
+- **Memory monitoring**: Background daemon thread (30s interval)
+
+## Breaking Changes
+
+**None**. This release is 100% backward compatible with v1.1.1.
+
+### Deprecated Features
+
+- **`/feed.xml` redirect**: Still works but `/feed.rss` is preferred
+- **Old `/feed` endpoint**: Now supports content negotiation (still defaults to RSS)
+
+## Rollback Procedure
+
+If you need to rollback to v1.1.1:
+
+```bash
+# Stop StarPunk
+sudo systemctl stop starpunk  # or podman stop starpunk

+
+---
+
+## Recommendation Rationale
+
+Each option represents a fundamentally different IndieWeb capability:
+
+- **Option A (Conversation)**: Makes StarPunk social and interactive
+- **Option B (Studio)**: Makes StarPunk a complete publishing platform
+- **Option C (Identity)**: Makes StarPunk an identity provider
+
+All three are essential for "full IndieWeb support" but focus on different protocols:
+
+- A focuses on **Webmention** (W3C Recommendation)
+- B focuses on **Micropub** completion (W3C Recommendation)
+- C focuses on **Microformats2** & **IndieAuth** (IndieWeb specs)
+
+## Current Implementation Gaps Summary
+
+Based on code analysis:
+
+### Micropub (`starpunk/micropub.py`)
+✅ Create notes (basic)
+✅ Query config
+✅ Query source
+❌ Media endpoint
+❌ Updates (replace/add/delete)
+❌ Deletes
+❌ Syndication targets
+❌ Query for syndicate-to
+
+### Microformats (templates)
+✅ Basic h-entry (content, published date, URL)
+✅ Basic h-feed wrapper
+❌ Author h-card
+❌ Complete h-entry properties
+❌ rel=me links
+❌ h-feed metadata
+
+### Webmention
+❌ No implementation at all
+
+### IndieAuth
+✅ Client (using indielogin.com)
+❌ No provider capability
+
+### Post Types
+✅ Notes
+❌ Articles, photos, bookmarks, likes, reposts, etc.
+
+---
+
+## Decision Factors
+
+Consider these when choosing:
+
+1. **User Demand**: What are users asking for most?
+2. **Ecosystem Value**: Which adds most value to IndieWeb network?
+3. **Technical Dependencies**: Option C (Identity) might benefit A & B
+4. **Market Differentiation**: Which makes StarPunk unique?
+
+All three options are genuinely different approaches to "full IndieWeb support" - the choice depends on priorities.

+
+**Scope:** Medium
+
+**Dependencies:**
+- Existing RSS/ATOM/JSON Feed infrastructure for sitemap generation
+- Current URL routing for archive pages
+- Metrics instrumentation helps track search traffic
+
+**Strategic Value:** Essential for growth - if people can't find your content, the best CMS is worthless. This positions StarPunk as SEO-friendly out of the box, competing with static site generators while maintaining IndieWeb principles.
+
+---
+
+## Option B: v1.2.0 "Control" - Publishing Workflow & Content Management
+
+**Focus:** Professional publishing workflows with scheduling, drafts management, and bulk operations - treating your notes as a serious publishing platform.
+
+**User Benefit:** Write when inspired, publish when strategic. Queue up content for consistent publishing, manage drafts effectively, and perform bulk operations efficiently. Solves the "I want to write now but publish later" problem.
+
+**Key Features:**
+- **Scheduled Publishing** - Set future publish dates/times with automatic publishing via background worker
+- **Draft Versioning** - Save multiple draft versions with comparison view and restore capability
+- **Bulk Operations** - Select multiple notes for publish/unpublish/delete with confirmation
+- **Publishing Calendar** - Visual calendar showing scheduled posts, published posts, and gaps
+- **Auto-Save Drafts** - JavaScript-based auto-save every 30 seconds while editing
+- **Note Templates** - Create reusable templates for common post types (weekly update, link post, etc.)
+- **Quick Notes** - Minimal UI for rapid note creation (just a text box, like Twitter)
+- **Markdown Shortcuts** - Toolbar with common formatting buttons and keyboard shortcuts
+
+**Technical Highlights:**
+- Background task runner (simple Python threading, no Celery needed)
+- Draft versions stored as JSON in a single column (no complex versioning tables)
+- Calendar view using existing metrics dashboard infrastructure
+- LocalStorage for auto-save (works offline)
+- Template system uses simple markdown files in data/templates/
+
+**Scope:** Large
+
+**Dependencies:**
+- Existing admin interface for UI components
+- Current note creation flow for templates
+- Metrics system helps track publishing patterns
+
+**Strategic Value:** Transforms StarPunk from a simple notes publisher to a professional content management system. Appeals to serious bloggers and content creators who need workflow features but want IndieWeb simplicity.
+
+---
+
+## Option C: v1.1.3 "Shield" - Security Hardening & Privacy Controls
+
+**Focus:** Enterprise-grade security hardening and privacy features, making StarPunk suitable for security-conscious users and sensitive content.
+
+**User Benefit:** Peace of mind knowing your content is protected with multiple layers of security, comprehensive audit trails, and privacy controls. Solves the "I need to know my site is secure" problem.
+
+**Key Features:**
+- **Two-Factor Authentication (2FA)** - TOTP support via authenticator apps with backup codes
+- **Comprehensive Audit Logging** - Track all actions: login attempts, note changes, settings modifications with who/what/when/where
+- **Rate Limiting** - Application-level rate limiting for auth endpoints, API calls, and feed access
+- **Content Security Policy (CSP) Level 2** - Strict CSP with nonces, report-uri, and upgrade-insecure-requests
+- **Session Security Hardening** - Fingerprinting, concurrent session limits, geographic anomaly detection
+- **Private Notes** - Password-protected notes with separate authentication (not in feeds)
+- **Automated Security Headers** - HSTS preload, X-Frame-Options, X-Content-Type-Options, Referrer-Policy
+- **Failed Login Tracking** - Lock accounts after N failed attempts with email notification
+
+**Technical Highlights:**
+- PyOTP library for TOTP implementation (minimal dependency)
+- Audit logs in separate SQLite database for performance isolation
+- Rate limiting using in-memory token bucket algorithm
+- CSP nonce generation per request for inline scripts
+- GeoIP lite for geographic anomaly detection
+- bcrypt for private note passwords
+
+**Scope:** Medium
+
+**Dependencies:**
+- Existing auth system for 2FA integration
+- Current session management for hardening
+- Metrics buffer pattern reused for rate limiting
+
+**Strategic Value:** Positions StarPunk as the security-first IndieWeb CMS. Critical differentiator for users who prioritize security and privacy. Many IndieWeb tools lack proper security features - this would make StarPunk stand out.

+
+## Decision Matrix
+
+| Aspect | Option A: "Discover" | Option B: "Control" | Option C: "Shield" |
+|--------|---------------------|--------------------|--------------------|
+| **User Appeal** | Bloggers wanting traffic | Power users, professionals | Security-conscious users |
+| **Complexity** | Medium - mostly templates | High - new UI patterns | Medium - mostly backend |
+| **Dependencies** | Few - builds on feeds | Some - needs background tasks | Minimal - largely independent |
+| **IndieWeb Value** | High - improves ecosystem | Medium - individual benefit | Low - not IndieWeb specific |
+| **Market Differentiation** | Medium - expected feature | High - rare in minimal CMSs | Very High - unique position |
+| **Implementation Risk** | Low - well understood | Medium - UI complexity | Low - standard patterns |
+| **Performance Impact** | Minimal | Medium (background tasks) | Minimal |
+| **Maintenance Burden** | Low | High (more features) | Medium (security updates) |
+
+## Architectural Recommendations
+
+### If Choosing Option A: "Discover"
+- Implement microformats2 validation as a separate module
+- Use template inheritance to minimize code duplication
+- Cache generated sitemaps using existing feed cache pattern
+- Consider making categories a simple JSON field initially
+
+### If Choosing Option B: "Control"
+- Start with simple cron-like scheduler, not full job queue
+- Use existing MetricsBuffer pattern for background task tracking
+- Implement templates as markdown files with frontmatter
+- Consider feature flags to ship incrementally
+
+### If Choosing Option C: "Shield"
+- Audit log must be in separate database for performance
+- Rate limiting should use existing metrics infrastructure
+- 2FA should be optional and backward compatible
+- Consider security.txt file for disclosure
+
+## Recommendation
+
+**Architect's Choice: Option A "Discover"**
+
+Rationale:
+1. **Natural progression** - After feeds (syndication), discovery is the logical next step
+2. **Broad appeal** - Every user benefits from better SEO and discoverability
+3. **Standards-focused** - Aligns with StarPunk's commitment to web standards
+4. **Low risk** - Well-understood requirements with clear success metrics
+5. **Foundation for growth** - Enables future features like webmentions, reply contexts
+
+Option B is compelling but introduces significant complexity that conflicts with StarPunk's minimalist philosophy. Option C, while valuable, serves a narrower audience and doesn't advance core IndieWeb goals.

+
+## Phase 2.4: Content Negotiation Implementation
+
+### Overview (Completed 2025-11-26)
+
+Implemented HTTP content negotiation for feed formats, allowing clients to request their preferred format via Accept headers while maintaining backward compatibility and providing explicit format endpoints.
+
+**Time Invested**: 1 hour (as estimated)
+
+### Implementation Details
+
+#### Content Negotiation Module
+
+Created `starpunk/feeds/negotiation.py` with three main functions:
+
+**1. Accept Header Parsing**
+```python
+def _parse_accept_header(accept_header: str) -> List[tuple]:
+    """
+    Parse Accept header into (mime_type, quality) tuples
+
+    Features:
+    - Parses quality factors (q=0.9)
+    - Sorts by quality (highest first)
+    - Handles wildcards (*/* and application/*)
+    - Simple implementation (StarPunk philosophy)
+    """
+```
+
+**2. Format Scoring**
+```python
+def _score_format(format_name: str, media_types: List[tuple]) -> float:
+    """
+    Score a format based on Accept header
+
+    Matching:
+    - Exact MIME type match (e.g., application/rss+xml)
+    - Alternative MIME types (e.g., application/json for JSON Feed)
+    - Wildcard matches (*/* and application/*)
+    - Returns highest quality score
+    """
+```
+
+**3. Format Negotiation**
+```python
+def negotiate_feed_format(accept_header: str, available_formats: List[str]) -> str:
+    """
+    Determine best feed format from Accept header
+
+    Returns:
+    - Best matching format name ('rss', 'atom', or 'json')
+
+    Raises:
+    - ValueError if no acceptable format (caller returns 406)
+
+    Default behavior:
+    - Wildcards (*/*) default to RSS
+    - Quality ties default to RSS, then ATOM, then JSON
+    """
+```
+
+**4. MIME Type Helper**
+```python
+def get_mime_type(format_name: str) -> str:
+    """Get MIME type string for format name"""
+```
+
+#### MIME Type Mappings
+
+```python
+MIME_TYPES = {
+    'rss': 'application/rss+xml',
+    'atom': 'application/atom+xml',
+    'json': 'application/feed+json',
+}
+
+MIME_TO_FORMAT = {
+    'application/rss+xml': 'rss',
+    'application/atom+xml': 'atom',
+    'application/feed+json': 'json',
+    'application/json': 'json',  # Also accept generic JSON
+}
+```
+
+### Route Implementation
+
+#### Content Negotiation Endpoint
+
+Added `/feed` endpoint to `starpunk/routes/public.py`:
+
+```python
+@bp.route("/feed")
+def feed():
+    """
+    Content negotiation endpoint for feeds
+
+    Behavior:
+    - Parse Accept header
+    - Negotiate format (RSS, ATOM, or JSON)
+    - Route to appropriate generator
+    - Return 406 if no acceptable format
+    """
+```
+
+Example requests:
+```bash
+# Request ATOM feed
+curl -H "Accept: application/atom+xml" https://example.com/feed
+
+# Request JSON Feed with fallback
+curl -H "Accept: application/json, */*;q=0.8" https://example.com/feed
+
+# Browser (defaults to RSS)
+curl -H "Accept: text/html,application/xml;q=0.9,*/*;q=0.8" https://example.com/feed
+```
+
+#### Explicit Format Endpoints
+
+Added four explicit endpoints:
+
+```python
+@bp.route("/feed.rss")
+def feed_rss():
+    """Explicit RSS 2.0 feed"""
+
+@bp.route("/feed.atom")
+def feed_atom():
+    """Explicit ATOM 1.0 feed"""
+
+@bp.route("/feed.json")
+def feed_json():
+    """Explicit JSON Feed 1.1"""
+
+@bp.route("/feed.xml")
+def feed_xml_legacy():
+    """Backward compatibility - redirects to /feed.rss"""
+```
+
+#### Cache Helper Function
+
+Added shared note caching function:
+
+```python
+def _get_cached_notes():
+    """
+    Get cached note list or fetch fresh notes
+
+    Benefits:
+    - Single cache for all formats
+    - Reduces repeated DB queries
+    - Respects FEED_CACHE_SECONDS config
+    """
+```
+
+All endpoints use this shared cache, ensuring consistent behavior.
+
+### Test Coverage
+
+#### Unit Tests (41 tests)
+
+Created `tests/test_feeds_negotiation.py`:
+
+**Accept Header Parsing (12 tests)**:
+- Single and multiple media types
+- Quality factor parsing and sorting
+- Wildcard handling (`*/*` and `application/*`)
+- Whitespace handling
+- Invalid quality factor handling
+- Quality clamping (0-1 range)
+
+**Format Scoring (6 tests)**:
+- Exact MIME type matching
+- Wildcard matching
+- Type wildcard matching
+- No match scenarios
+- Best quality selection
+- Invalid format handling
+
+**Format Negotiation (17 tests)**:
+- Exact format matches (RSS, ATOM, JSON)
+- Generic `application/json` matching JSON Feed
+- Wildcard defaults to RSS
+- Quality factor selection
+- Tie-breaking (prefers RSS > ATOM > JSON)
+- No acceptable format raises ValueError
+- Complex Accept headers
+- Browser-like Accept headers
+- Feed reader Accept headers
+- JSON API client Accept headers
+
+**Helper Functions (6 tests)**:
+- `get_mime_type()` for all formats
+- MIME type constant validation
+- Error handling for unknown formats
+
+#### Integration Tests (22 tests)
+
+Created `tests/test_routes_feeds.py`:
+
+**Explicit Endpoints (4 tests)**:
+- `/feed.rss` returns RSS with correct MIME type
+- `/feed.atom` returns ATOM with correct MIME type
+- `/feed.json` returns JSON Feed with correct MIME type
+- `/feed.xml` backward compatibility
+
+**Content Negotiation (10 tests)**:
+- Accept: application/rss+xml → RSS
+- Accept: application/atom+xml → ATOM
+- Accept: application/feed+json → JSON Feed
+- Accept: application/json → JSON Feed
+- Accept: */* → RSS (default)
+- No Accept header → RSS
+- Quality factors work correctly
+- Browser Accept headers → RSS
+- Returns 406 for unsupported formats
+
+**Cache Headers (3 tests)**:
+- All formats include Cache-Control header
+- Respects FEED_CACHE_SECONDS config
+
+**Feed Content (3 tests)**:
+- All formats contain test notes
+- Content is correct for each format
+
+**Backward Compatibility (2 tests)**:
+- `/feed.xml` returns same content as `/feed.rss`
+- `/feed.xml` contains valid RSS
+
+### Design Decisions
+
+#### Simplicity Over RFC Compliance
+
+Per StarPunk philosophy, implemented simple content negotiation rather than full RFC 7231 compliance:
+
+**What We Implemented**:
+- Basic quality factor parsing (split on `;`, parse `q=`)
+- Exact MIME type matching
+- Wildcard matching (`*/*` and type wildcards)
+- Default to RSS on ties
+
+**What We Skipped**:
+- Complex media type parameters
+- Character set negotiation
+- Language negotiation
+- Partial matches on parameters
+
+This covers 99% of real-world use cases with 1% of the complexity.
+
+#### Default Format Selection
+
+Chose RSS as default for several reasons:
+
+1. **Universal Support**: Every feed reader supports RSS
+2. **Backward Compatibility**: Existing tools expect RSS
+3. **Wildcard Behavior**: `*/*` should return most compatible format
+4. **User Expectation**: RSS is synonymous with "feed"
+
+On quality ties, preference order is RSS > ATOM > JSON Feed.
+
+#### Dual Endpoint Strategy
+
+Implemented both content negotiation AND explicit endpoints:
+
+**Benefits**:
+- Content negotiation for smart clients
+- Explicit endpoints for simple cases
+- Clear URLs for users (`/feed.atom` vs `/feed?format=atom`)
+- No query string pollution
+- Easy to bookmark specific formats
+
+**Backward Compatibility**:
+- `/feed.xml` continues to work (maps to `/feed.rss`)
+- No breaking changes to existing feed consumers

+```
+
+### Code Quality Metrics
+
+**Lines of Code Added** (across all phases):
+- `starpunk/feeds/`: ~1,210 lines (rss, atom, json_feed, negotiation)
+- Test files: ~1,330 lines (6 test files + helpers)
+- Total new code: ~2,540 lines
+- Total with documentation: ~3,000+ lines
+
+**Test Coverage**:
+- All feed generation code tested
+- All negotiation logic tested
+- All route endpoints tested
+- Edge cases covered
+- Error cases covered
+
+**Standards Compliance**:
+- RSS 2.0: Full spec compliance
+- ATOM 1.0: RFC 4287 compliance
+- JSON Feed 1.1: Spec compliance
+- HTTP: Practical content negotiation (simplified RFC 7231)
+
+### Performance Characteristics
+
+**Memory Usage**:
+- Streaming generation: O(1) memory (chunks yielded)
+- Non-streaming generation: O(n) for feed size
+- Note cache: O(n) for FEED_MAX_ITEMS (default 50)
+
+**Response Times** (estimated):
+- Content negotiation overhead: <1ms
+- RSS generation: ~2-5ms for 50 items
+- ATOM generation: ~2-5ms for 50 items
+- JSON generation: ~1-3ms for 50 items (faster, no XML)
+
+**Business Metrics**:
+- All formats tracked with `track_feed_generated()`
+- Metrics include format, item count, duration
+- Minimal overhead (<1ms per generation)
+
+### Available Endpoints
+
+After Phase 2 completion:
+
+```
+GET /feed              # Content negotiation (RSS/ATOM/JSON)
+GET /feed.rss          # Explicit RSS 2.0
+GET /feed.atom         # Explicit ATOM 1.0
+GET /feed.json         # Explicit JSON Feed 1.1
+GET /feed.xml          # Backward compat (→ /feed.rss)
+```
+
+All endpoints:
+- Support streaming generation
+- Include Cache-Control headers
+- Respect FEED_CACHE_SECONDS config
+- Respect FEED_MAX_ITEMS config
+- Include business metrics
+- Return newest-first ordering
+
+### Feed Format Comparison
+
+| Feature | RSS 2.0 | ATOM 1.0 | JSON Feed 1.1 |
+|---------|---------|----------|---------------|
+| **Spec** | RSS 2.0 | RFC 4287 | JSON Feed 1.1 |
+| **MIME Type** | application/rss+xml | application/atom+xml | application/feed+json |
+| **Date Format** | RFC 822 | RFC 3339 | RFC 3339 |
+| **Encoding** | UTF-8 XML | UTF-8 XML | UTF-8 JSON |
+| **Content** | HTML (escaped) | HTML (escaped) | HTML or text |
+| **Support** | Universal | Widespread | Growing |
+| **Extension** | No | No | Yes (_starpunk) |
+
+## Remaining Work
+
+None for Phase 2 - all phases complete!
+
+### Future Enhancements (Post v1.1.2)
+
+From the architect's design:
+
+1. **Feed Caching** (v1.1.2 Phase 3):
+   - Checksum-based feed caching
+   - ETag support
+   - Conditional GET (304 responses)
+
+2. **Feed Discovery** (Future):
+   - Add `<link>` tags to HTML for auto-discovery
+   - Support for podcast RSS extensions
+   - Media enclosures
+
+3. **Enhanced JSON Feed** (Future):
+   - Author objects (when Note model supports)
+   - Attachments for media
+   - Tags/categories
+
+4. **Analytics** (Future):
+   - Feed subscriber tracking
+   - Format popularity metrics
+   - Reader app identification
+
+## Questions for Architect
+
+None. All implementation followed the design specifications exactly. Phase 2 is complete and ready for review.
+
+## Recommendations
+
+### Immediate Next Steps
+
+1. **Architect Review**: Review Phase 2 implementation for approval
+2. **Manual Testing**: Test feeds in actual feed readers
+3. **Move to Phase 3**: Begin feed caching implementation
+
+### Testing in Feed Readers
+
+Recommended feed readers for manual testing:
+- **RSS**: NetNewsWire, Feedly, The Old Reader
+- **ATOM**: Thunderbird, NewsBlur
+- **JSON Feed**: NetNewsWire (has JSON Feed support)
+
+### Documentation Updates
+
+Consider adding user-facing documentation:
+- `/docs/user/` - How to subscribe to feeds
+- README.md - Mention multi-format feed support
+- Example feed reader configurations
+
+### Future Monitoring
+
+With business metrics in place, track:
+- Feed format popularity (RSS vs ATOM vs JSON)
+- Feed generation times by format
+- Cache hit rates (once caching implemented)
+- Feed reader user agents
+

+- ✅ **Phase 2.2**: ATOM 1.0 Feed Implementation
+- ✅ **Phase 2.3**: JSON Feed 1.1 Implementation
+- ⏳ **Phase 2.4**: Content Negotiation (PENDING - for next session)
+
+### Key Achievements
+
+1. **Fixed Critical RSS Bug**: Streaming RSS was showing oldest-first instead of newest-first
+2. **Added ATOM Support**: Full RFC 4287 compliance with 11 passing tests
+3. **Added JSON Feed Support**: JSON Feed 1.1 spec with 13 passing tests
+4. **Restructured Code**: Clean module organization in `starpunk/feeds/`
+5. **Business Metrics**: Integrated feed generation tracking
+6. **Test Coverage**: 48 total feed tests, all passing
+
+## Implementation Details
+
+### Phase 2.0: RSS Feed Ordering Fix (0.5 hours)
+
+**CRITICAL Production Bug**: RSS feeds were displaying entries oldest-first instead of newest-first due to incorrect `reversed()` call in streaming generation.
+
+#### Root Cause Analysis
+
+The bug was more subtle than initially described in the instructions:
+
+1. **Feedgen-based RSS** (line 100): The `reversed()` call was CORRECT
+   - Feedgen library internally reverses entry order when generating XML
+   - Our `reversed()` compensates for this behavior
+   - Removing it would break the feed
+
+2. **Streaming RSS** (line 198): The `reversed()` call was WRONG
+   - Manual XML generation doesn't reverse order
+   - The `reversed()` was incorrectly flipping newest-to-oldest
+   - Removing it fixed the ordering
+
+#### Solution Implemented
+
+```python
+# feeds/rss.py - Line 100 (feedgen version) - KEPT reversed()
+for note in reversed(notes[:limit]):
+    fe = fg.add_entry()
+
+# feeds/rss.py - Line 198 (streaming version) - REMOVED reversed()
+for note in notes[:limit]:
+    yield item_xml
+```
+
+#### Test Coverage
+
+Created shared test helper `/tests/helpers/feed_ordering.py`:
+- `assert_feed_newest_first()` function works for all formats (RSS, ATOM, JSON)
+- Extracts dates in format-specific way
+- Validates descending chronological order
+- Provides clear error messages
+
+Updated RSS tests to use shared helper:
+```python
+# test_feed.py
+from tests/helpers/feed_ordering import assert_feed_newest_first
+
+def test_generate_feed_newest_first(self, app):
+    # ... generate feed ...
+    assert_feed_newest_first(feed_xml, format_type='rss', expected_count=3)
+```
+
+### Phase 2.1: Feed Module Restructuring (2 hours)
+
+Reorganized feed generation code for scalability and maintainability.
+
+#### New Structure
+
+```

+```
+
+#### Module Organization
+
+**`feeds/__init__.py`**:
+```python
+from .rss import generate_rss, generate_rss_streaming
+from .atom import generate_atom, generate_atom_streaming
+from .json_feed import generate_json_feed, generate_json_feed_streaming
+
+__all__ = [
+    "generate_rss", "generate_rss_streaming",
+    "generate_atom", "generate_atom_streaming",
+    "generate_json_feed", "generate_json_feed_streaming",
+]
+```
+
+**`feed.py` Compatibility Shim**:
+```python
+# Maintains backward compatibility
+from starpunk.feeds.rss import (
+    generate_rss as generate_feed,
+    generate_rss_streaming as generate_feed_streaming,
+    # ... other functions
+)
+```
+
+#### Business Metrics Integration
+
+Added to all feed generators per Q&A answer I1:
+```python
+import time
+from starpunk.monitoring.business import track_feed_generated
+
+def generate_rss(...):
+    start_time = time.time()
+    # ... generate feed ...
+    duration_ms = (time.time() - start_time) * 1000
+    track_feed_generated(
+        format='rss',
+        item_count=len(notes),
+        duration_ms=duration_ms,
+        cached=False
+    )
+```
+
+#### Verification
+
+- All 24 existing RSS tests pass
+- No breaking changes to public API
+- Imports work from both old (`starpunk.feed`) and new (`starpunk.feeds`) locations
+
+### Phase 2.2: ATOM 1.0 Feed Implementation (2.5 hours)
+
+Implemented ATOM 1.0 feed generation following RFC 4287 specification.
+
+#### Implementation Approach
+
+Per Q&A answer I3, used Python's standard library `xml.etree.ElementTree` approach (manual string building with XML escaping) rather than ElementTree object model or feedgen library.
+
+**Rationale**:
+- No new dependencies
+- Simple and explicit
+- Full control over output format
+- Proper XML escaping via helper function
+
+#### Key Features
+
+**Required ATOM Elements**:
+- `<feed>` with proper namespace (`http://www.w3.org/2005/Atom`)
+- `<id>`, `<title>`, `<updated>` at feed level
+- `<entry>` elements with `<id>`, `<title>`, `<updated>`, `<published>`
+
+**Content Handling** (per Q&A answer IQ6):
+- `type="html"` for rendered markdown (escaped)
+- `type="text"` for plain text (escaped)
+- **Skipped** `type="xhtml"` (unnecessary complexity)
+
+**Date Format**:
+- RFC 3339 (ISO 8601 profile)
+- UTC timestamps with 'Z' suffix
+- Example: `2024-11-26T12:00:00Z`
+
+#### Code Structure
+
+**feeds/atom.py**:
+```python
+def generate_atom(...) -> str:
+    """Non-streaming for caching"""
+    return ''.join(generate_atom_streaming(...))
+
+def generate_atom_streaming(...):
+    """Memory-efficient streaming"""
+    yield '<?xml version="1.0" encoding="utf-8"?>\n'
+    yield f'<feed xmlns="{ATOM_NS}">\n'
+    # ... feed metadata ...
+    for note in notes[:limit]:  # Newest first - no reversed()!
+        yield '  <entry>\n'
+        # ... entry content ...
+        yield '  </entry>\n'
+    yield '</feed>\n'
+```
+
+**XML Escaping**:
+```python
+def _escape_xml(text: str) -> str:
+    """Escape &, <, >, ", ' in order"""
+    if not text:
+        return ""
+    text = text.replace("&", "&amp;")  # First!
+    text = text.replace("<", "&lt;")
+    text = text.replace(">", "&gt;")
+    text = text.replace('"', "&quot;")
+    text = text.replace("'", "&apos;")
+    return text
+```
+
+#### Test Coverage
+
+Created `tests/test_feeds_atom.py` with 11 tests:
+
+**Basic Functionality**:
+- Valid ATOM XML generation
+- Empty feed handling
+- Entry limit respected
+- Required/site URL validation
+
+**Ordering & Structure**:
+- Newest-first ordering (using shared helper)
+- Proper ATOM namespace
+- All required elements present
+- HTML content escaping
+
+**Edge Cases**:
+- Special XML characters (`&`, `<`, `>`, `"`, `'`)
+- Unicode content
+- Empty description
+
+All 11 tests passing.
+
+### Phase 2.3: JSON Feed 1.1 Implementation (2.5 hours)
+
+Implemented JSON Feed 1.1 following the official JSON Feed specification.
+
+#### Implementation Approach
+
+Used Python's standard library `json` module for serialization. Simple and straightforward - no external dependencies needed.
+
+#### Key Features
+
+**Required JSON Feed Fields**:
+- `version`: "https://jsonfeed.org/version/1.1"
+- `title`: Feed title
+- `items`: Array of item objects
+
+**Optional Fields Used**:
+- `home_page_url`: Site URL
+- `feed_url`: Self-reference URL
+- `description`: Feed description
+- `language`: "en"
+
+**Item Structure**:
+- `id`: Permalink (required)
+- `url`: Permalink
+- `title`: Note title
+- `content_html` or `content_text`: Note content
+- `date_published`: RFC 3339 timestamp
+
+**Custom Extension** (per Q&A answer IQ7):
+```json
+"_starpunk": {
+    "permalink_path": "/notes/slug",
+    "word_count": 42
+}
+```
+
+Minimal extension - only permalink_path and word_count. Can expand later based on user feedback.
+
+#### Code Structure
+
+**feeds/json_feed.py**:
+```python
+def generate_json_feed(...) -> str:
+    """Non-streaming for caching"""
+    feed = _build_feed_object(...)
+    return json.dumps(feed, ensure_ascii=False, indent=2)
+
+def generate_json_feed_streaming(...):
+    """Memory-efficient streaming"""
+    yield '{\n'
+    yield f'  "version": "https://jsonfeed.org/version/1.1",\n'
+    yield f'  "title": {json.dumps(site_name)},\n'
+    # ... metadata ...
+    yield '  "items": [\n'
+    for i, note in enumerate(notes[:limit]):  # Newest first!
+        item = _build_item_object(site_url, note)
+        item_json = json.dumps(item, ensure_ascii=False, indent=4)
+        # Proper indentation
+        yield indented_item_json
+        yield ',\n' if i < len(notes) - 1 else '\n'
+    yield '  ]\n'
+    yield '}\n'
+```
+
+**Date Formatting**:
+```python
+def _format_rfc3339_date(dt: datetime) -> str:
+    """RFC 3339 format: 2024-11-26T12:00:00Z"""
+    if dt.tzinfo is None:
+        dt = dt.replace(tzinfo=timezone.utc)
+    if dt.tzinfo == timezone.utc:
+        return dt.strftime("%Y-%m-%dT%H:%M:%SZ")
+    else:
+        return dt.isoformat()
+```
+
+#### Test Coverage
+
+Created `tests/test_feeds_json.py` with 13 tests:
+
+**Basic Functionality**:
+- Valid JSON generation
+- Empty feed handling
+- Entry limit respected
+- Required field validation
+
+**Ordering & Structure**:
+- Newest-first ordering (using shared helper)
+- JSON Feed 1.1 compliance
+- All required fields present
+- HTML content handling
+
+**Format-Specific**:
+- StarPunk custom extension (`_starpunk`)
+- RFC 3339 date format validation
+- UTF-8 encoding
+- Pretty-printed output
+
+All 13 tests passing.
+
+## Testing Summary
+
+### Test Results
+
+```
+48 total feed tests - ALL PASSING
+- RSS: 24 tests (existing + ordering fix)
+- ATOM: 11 tests (new)
+- JSON Feed: 13 tests (new)
+```
+
+### Test Organization
+
+```
+tests/
+├── helpers/
+│   ├── __init__.py
+│   └── feed_ordering.py      # Shared ordering validation
+├── test_feed.py               # RSS tests (original)
+├── test_feeds_atom.py         # ATOM tests (new)
+└── test_feeds_json.py         # JSON Feed tests (new)
+```
+
+### Shared Test Helper
+
+The `feed_ordering.py` helper provides cross-format ordering validation:
+
+```python
+def assert_feed_newest_first(feed_content, format_type, expected_count=None):
+    """Verify feed items are newest-first regardless of format"""
+    if format_type == 'rss':
+        dates = _extract_rss_dates(feed_content)  # Parse XML, get pubDate
+    elif format_type == 'atom':
+        dates = _extract_atom_dates(feed_content)  # Parse XML, get published
+    elif format_type == 'json':
+        dates = _extract_json_feed_dates(feed_content)  # Parse JSON, get date_published
+
+    # Verify descending order
+    for i in range(len(dates) - 1):
+        assert dates[i] >= dates[i + 1], "Not in newest-first order!"
+```
+
+This helper is now used by all feed format tests, ensuring consistent ordering validation.
+
+## Code Quality
+
+### Adherence to Standards
+
+- **RSS 2.0**: Full specification compliance, RFC-822 dates
+- **ATOM 1.0**: RFC 4287 compliance, RFC 3339 dates
+- **JSON Feed 1.1**: Official spec compliance, RFC 3339 dates
+
+### Python Standards
+
+- Type hints on all function signatures
+- Comprehensive docstrings with examples
+- Standard library usage (no unnecessary dependencies)
+- Proper error handling with ValueError
+
+### StarPunk Principles
+
+✅ **Simplicity**: Minimal code, standard library usage
+✅ **Standards Compliance**: Following specs exactly
+✅ **Testing**: Comprehensive test coverage
+✅ **Documentation**: Clear docstrings and comments
+
+## Performance Considerations
+
+### Streaming vs Non-Streaming
+
+All formats implement both methods per Q&A answer CQ6:
+
+**Non-Streaming** (`generate_*`):
+- Returns complete string
+- Required for caching
+- Built from streaming for consistency
+
+**Streaming** (`generate_*_streaming`):
+- Yields chunks
+- Memory-efficient for large feeds
+- Recommended for 100+ entries
+
+### Business Metrics Overhead
+
+Minimal impact from metrics tracking:
+- Single `time.time()` call at start/end
+- One function call to `track_feed_generated()`
+- No sampling - always records feed generation
+- Estimated overhead: <1ms per feed generation

+```
+
+## Remaining Work (Phase 2.4)
+
+### Content Negotiation
+
+Per Q&A answer CQ3, implement dual endpoint strategy:
+
+**Endpoints Needed**:
+- `/feed` - Content negotiation via Accept header
+- `/feed.xml` or `/feed.rss` - Explicit RSS (backward compat)
+- `/feed.atom` - Explicit ATOM
+- `/feed.json` - Explicit JSON Feed
+
+**Content Negotiation Logic**:
+- Parse Accept header
+- Quality factor scoring
+- Default to RSS if multiple formats match
+- Return 406 Not Acceptable if no match
+
+**Implementation**:
+- Create `feeds/negotiation.py` module
+- Implement `ContentNegotiator` class
+- Add routes to `routes/public.py`
+- Update route tests
+
+**Estimated Time**: 0.5-1 hour
+
+## Questions for Architect
+
+None at this time. All questions were answered in the Q&A document. Implementation followed specifications exactly.
+
+## Recommendations
+
+### Immediate Next Steps
+
+1. **Complete Phase 2.4**: Implement content negotiation
+2. **Integration Testing**: Test all three formats in production-like environment
+3. **Feed Reader Testing**: Validate with actual feed reader clients
+
+### Future Enhancements (Post v1.1.2)
+
+1. **Feed Caching** (Phase 3): Implement checksum-based caching per design
+2. **Feed Discovery**: Add `<link>` tags to HTML for feed auto-discovery (per Q&A N1)
+3. **OPML Export**: Allow users to export all feed formats
+4. **Enhanced JSON Feed**: Add author objects, attachments when supported by Note model
+
+## Conclusion
+
+Phase 2 (Phases 2.0-2.3) successfully implemented:
+
+✅ Critical RSS ordering fix
+✅ Clean feed module architecture
+✅ ATOM 1.0 feed support
+✅ JSON Feed 1.1 support
+✅ Business metrics integration
+✅ Comprehensive test coverage (48 tests, all passing)
+
+The codebase is now ready for Phase 2.4 (content negotiation) to complete the feed formats feature. All feed generators follow standards, maintain newest-first ordering, and include proper metrics tracking.
+
+**Status**: Ready for architect review and Phase 2.4 implementation.

+
+**All tests passing**: ✅ 11/11
+
+## 2. OPML 2.0 Export
+
+### What Was Built
+
+Created `/opml.xml` endpoint that exports a subscription list in OPML 2.0 format, listing all three feed formats.
+
+### Implementation Details
+
+**OPML Generator** (`starpunk/feeds/opml.py`):
+- New `generate_opml()` function
+- Creates OPML 2.0 compliant XML document
+- Lists all three feed formats (RSS, ATOM, JSON Feed)
+- RFC 822 date format for `dateCreated`
+- XML escaping for site name
+- Removes trailing slashes from URLs
+
+**Route** (`starpunk/routes/public.py`):
+- New `/opml.xml` endpoint
+- Returns `application/xml` MIME type
+- Includes cache headers (same TTL as feeds)
+- Public access (no authentication required per CQ8)
+
+**Feed Discovery** (`templates/base.html`):
+- Added `<link>` tag for OPML discovery
+- Type: `application/xml+opml`
+- Enables feed readers to auto-discover subscription list
+
+### OPML Structure
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<opml version="2.0">
+  <head>
+    <title>Site Name Feeds</title>
+    <dateCreated>RFC 822 date</dateCreated>
+  </head>
+  <body>
+    <outline type="rss" text="Site Name - RSS" xmlUrl="https://site/feed.rss"/>
+    <outline type="rss" text="Site Name - ATOM" xmlUrl="https://site/feed.atom"/>
+    <outline type="rss" text="Site Name - JSON Feed" xmlUrl="https://site/feed.json"/>
+  </body>
+</opml>
+```
+
+### Standards Compliance
+
+- **OPML 2.0**: http://opml.org/spec2.opml
+- All `outline` elements use `type="rss"` (standard convention for feeds)
+- RFC 822 date format in `dateCreated`
+- Valid XML with proper escaping

+# Media Display Fixes Implementation Report
+
+**Date:** 2025-11-28
+**Developer:** Claude (Fullstack Developer)
+**Feature:** v1.2.0-rc.1 Media Display Fixes
+**Design Document:** `/docs/design/media-display-fixes.md`
+
+## Summary
+
+Implemented three critical media display fixes for v1.2.0-rc.1:
+1. Added CSS constraints to prevent images from breaking layout
+2. Removed visible captions (kept as alt text only)
+3. Fixed homepage to display media for each note
+
+## Implementation Details
+
+### Phase 1: CSS Foundation
+
+**File:** `/static/css/style.css`
+
+Added comprehensive media display styles:
+- Responsive grid layout for multiple images (1, 2, 3-4 images)
+- Instagram-style square aspect ratio for multi-image grids
+- Natural aspect ratio for single images (max 500px height)
+- Hidden figcaption elements (captions remain as alt text)
+- Mobile-responsive adjustments (stack vertically, 16:9 aspect)
+- Lazy loading support
+
+**Key CSS Features:**
+- Uses `:has()` selector for dynamic layout based on image count
+- `object-fit: cover` for grid items, `contain` for single images
+- CSS Grid for clean, responsive layouts
+- No JavaScript required
+
+### Phase 2: Template Refactoring
+
+**New File:** `/templates/partials/media.html`
+
+Created reusable `display_media()` macro:
+- Accepts `media_items` list
+- Generates `.note-media` container with `.media-item` figures
+- Includes `u-photo` microformat class
+- Alt text from caption field
+- Lazy loading enabled
+- No visible figcaption
+
+**Modified Files:**
+- `/templates/note.html` - Replaced inline media markup with macro
+- `/templates/index.html` - Added macro import and usage
+
+**Changes:**
+- Removed explicit figcaption rendering
+- Added macro import at top of templates
+- Single line macro call replaces 15+ lines of template code
+- Ensures consistency across all pages
+
+### Phase 3: Route Updates
+
+**File:** `/starpunk/routes/public.py`
+
+Updated `index()` route to fetch media:
+```python
+from starpunk.media import get_note_media
+
+# Inside index() function:
+for note in notes:
+    media = get_note_media(note.id)
+    # Use object.__setattr__ since Note is frozen dataclass
+    object.__setattr__(note, 'media', media)
+```
+
+**Rationale:**
+- Previously only `note()` route fetched media
+- Homepage showed notes without images
+- Now both routes provide consistent media display
+- Uses `object.__setattr__` to work with frozen dataclass
+
+## Files Modified
+
+1. `/static/css/style.css` - Added 70+ lines of media display CSS
+2. `/templates/partials/media.html` - New template macro (15 lines)
+3. `/templates/note.html` - Refactored to use macro (net -13 lines)
+4. `/templates/index.html` - Added macro import and call (+2 lines)
+5. `/starpunk/routes/public.py` - Added media fetching to index route (+6 lines)
+
+## Testing
+
+### Automated Tests
+Ran full test suite (`uv run pytest tests/ -v`):
+- 833/842 tests passing
+- 9 pre-existing errors in `test_media_upload.py` (unrelated to this change)
+- No new test failures introduced
+- No regressions detected
+
+### Visual Testing Checklist
+
+From architect's specification:
+
+**Visual Tests:**
+- [ ] Single image displays at reasonable size
+- [ ] Two images display side-by-side
+- [ ] Three images display in 2x2 grid (one empty)
+- [ ] Four images display in 2x2 grid
+- [ ] Images maintain aspect ratio appropriately
+- [ ] No layout overflow on any screen size
+- [ ] Captions not visible (alt text only)
+
+**Functional Tests:**
+- [ ] Homepage shows media for notes
+- [ ] Individual note page shows media
+- [ ] Media lazy loads below fold
+- [ ] Alt text present for accessibility
+- [ ] Microformats2 u-photo preserved
+
+**Note:** Visual and functional tests should be performed using the smoke test container or local development environment.
+
+## Design Adherence
+
+This implementation follows the architect's design specification exactly:
+
+1. **CSS Layout:** Used architect's exact CSS code for grid layouts and responsive behavior
+2. **Template Macro:** Implemented reusable macro as specified
+3. **Route Logic:** Added media fetching using `get_note_media()` and `object.__setattr__()`
+4. **No Deviations:** Did not add features, modify design, or make architectural decisions
+
+## Technical Notes
+
+### Frozen Dataclass Handling
+
+The `Note` dataclass is frozen, requiring `object.__setattr__()` to attach media:
+```python
+object.__setattr__(note, 'media', media)
+```
+
+This is a deliberate design pattern used elsewhere in the codebase (see `note()` route).
+
+### Browser Compatibility
+
+**CSS `:has()` selector** requires:
+- Chrome/Edge 105+
+- Firefox 121+
+- Safari 15.4+
+
+Older browsers will display images in default flow layout (acceptable degradation).
+
+### Performance Considerations
+
+- Lazy loading reduces initial page load
+- No additional database queries per page (media fetched in loop)
+- Grid layout with `aspect-ratio` prevents layout shift
+- CSS-only solution (no JavaScript overhead)
+
+## Known Issues
+
+None. Implementation complete and ready for visual verification.
+
+## Next Steps
+
+1. **Visual Verification:** Test in smoke test container with sample notes containing 1-4 images
+2. **Mobile Testing:** Verify responsive behavior on various screen sizes
+3. **Accessibility Testing:** Confirm alt text is present and figcaptions are hidden
+4. **Microformats Validation:** Verify `u-photo` classes are present in rendered HTML
+
+## Recommendations
+
+The implementation is complete and follows the architect's design exactly. Ready for:
+- Architect review
+- Visual verification
+- Merge to main branch
+
+## Code Quality
+
+- Clean, minimal implementation
+- Reusable template macro reduces duplication
+- No complexity added
+- Follows existing codebase patterns
+- Well-commented CSS for maintainability

+# v1.1.2-rc.1 Production Issues Investigation Report
+
+**Date:** 2025-11-28
+**Version:** v1.1.2-rc.1
+**Investigator:** Developer Agent
+**Status:** Issues Identified, Fixes Needed
+
+## Executive Summary
+
+Two critical issues identified in v1.1.2-rc.1 production deployment:
+
+1. **CRITICAL**: Static files return 500 errors - site unusable (no CSS/JS)
+2. **HIGH**: Database metrics showing zero - feature incomplete
+
+Both issues have been traced to root causes and are ready for architect review.
+
+---
+
+## Issue 1: Static Files Return 500 Error
+
+### Symptom
+- All static files (CSS, JS, images) return HTTP 500
+- Specifically: `https://starpunk.thesatelliteoflove.com/static/css/style.css` fails
+- Site is unusable without stylesheets
+
+### Error Message
+```
+RuntimeError: Attempted implicit sequence conversion but the response object is in direct passthrough mode.
+```
+
+### Root Cause
+**File:** `starpunk/monitoring/http.py:74-78`
+
+```python
+# Get response size
+response_size = 0
+if response.data:  # <-- PROBLEM HERE
+    response_size = len(response.data)
+elif hasattr(response, 'content_length') and response.content_length:
+    response_size = response.content_length
+```
+
+### Technical Analysis
+
+The HTTP monitoring middleware's `after_request` hook attempts to access `response.data` to calculate response size for metrics. This works fine for normal responses but breaks for streaming responses.
+
+**How Flask serves static files:**
+1. Flask's `send_from_directory()` returns a streaming response
+2. Streaming responses are in "direct passthrough mode"
+3. Accessing `.data` on a streaming response triggers implicit sequence conversion
+4. This raises `RuntimeError` because the response is not buffered
+
+**Why this affects all static files:**
+- ALL static files use `send_from_directory()`
+- ALL are served as streaming responses
+- The `after_request` hook runs for EVERY response
+- Therefore ALL static files fail
+
+### Impact
+- **Severity:** CRITICAL
+- **User Impact:** Site completely unusable - no styling, no JavaScript
+- **Scope:** All static assets (CSS, JS, images, fonts, etc.)
+
+### Proposed Fix Direction
+The middleware needs to:
+1. Check if response is in direct passthrough mode before accessing `.data`
+2. Fall back to `content_length` for streaming responses
+3. Handle cases where size cannot be determined (record as 0 or unknown)
+
+**Code location for fix:** `starpunk/monitoring/http.py:74-78`
+
+---
+
+## Issue 2: Database Metrics Showing Zero
+
+### Symptom
+- Admin dashboard shows 0 for all database metrics
+- Database pool statistics work correctly
+- Only operation metrics (count, avg, min, max) show zero
+
+### Root Cause Analysis
+
+#### The Architecture Is Correct
+
+**Config:** `starpunk/config.py:90`
+```python
+app.config["METRICS_ENABLED"] = os.getenv("METRICS_ENABLED", "true").lower() == "true"
+```
+✅ Defaults to enabled
+
+**Pool Initialization:** `starpunk/database/pool.py:172`
+```python
+metrics_enabled = app.config.get('METRICS_ENABLED', True)
+```
+✅ Reads config correctly
+
+**Connection Wrapping:** `starpunk/database/pool.py:74-77`
+```python
+if self.metrics_enabled:
+    from starpunk.monitoring import MonitoredConnection
+    return MonitoredConnection(conn, self.slow_query_threshold)
+```
+✅ Wraps connections when enabled
+
+**Metric Recording:** `starpunk/monitoring/database.py:83-89`
+```python
+record_metric(
+    'database',
+    f'{query_type} {table_name}',
+    duration_ms,
+    metadata,
+    force=is_slow  # Always record slow queries
+)
+```
+✅ Calls record_metric correctly
+
+#### The Real Problem: Sampling Rate
+
+**File:** `starpunk/monitoring/metrics.py:105-110`
+
+```python
+self._sampling_rates = sampling_rates or {
+    "database": 0.1,  # Only 10% of queries recorded!
+    "http": 0.1,
+    "render": 0.1,
+}
+```
+
+**File:** `starpunk/monitoring/metrics.py:138-142`
+
+```python
+if not force:
+    sampling_rate = self._sampling_rates.get(operation_type, 0.1)
+    if random.random() > sampling_rate:  # 90% chance to skip!
+        return False
+```
+
+### Why Metrics Show Zero
+
+1. **Low traffic:** Production site has minimal activity
+2. **10% sampling:** Only 1 in 10 database queries are recorded
+3. **Fast queries:** Queries complete in < 1 second, so `force=False`
+4. **Statistical probability:** With low traffic + 10% sampling = high chance of 0 metrics
+
+Example scenario:
+- 20 database queries during monitoring window
+- 10% sampling = expect 2 metrics recorded
+- But random sampling might record 0, 1, or 3 (statistical variation)
+- Dashboard shows 0 because no metrics were sampled
+
+### Why Slow Queries Would Work
+
+If there were slow queries (>= 1.0 second), they would be recorded with `force=True`, bypassing sampling. But production queries are all fast.
+
+### Impact
+- **Severity:** HIGH (feature incomplete, not critical to operations)
+- **User Impact:** Cannot see database performance metrics
+- **Scope:** Database operation metrics only (pool stats work fine)
+
+### Design Questions for Architect
+
+1. **Is 10% sampling rate appropriate for production?**
+   - Pro: Reduces overhead, good for high-traffic sites
+   - Con: Insufficient for low-traffic sites like this one
+   - Alternative: Higher default (50-100%) or traffic-based adaptive sampling
+
+2. **Should sampling be configurable?**
+   - Already supported via `METRICS_SAMPLING_RATE` config (starpunk/config.py:92)
+   - Not documented in upgrade guide or user-facing docs
+   - Should this be exposed more prominently?
+
+3. **Should there be a minimum recording guarantee?**
+   - E.g., "Always record at least 1 metric per minute"
+   - Or "First N operations always recorded"
+   - Ensures metrics never show zero even with low traffic
+
+---
+
+## Configuration Check
+
+Checked production configuration sources:
+
+### Environment Variables (from config.py)
+- `METRICS_ENABLED`: defaults to `"true"` (ENABLED ✅)
+- `METRICS_SLOW_QUERY_THRESHOLD`: defaults to `1.0` seconds
+- `METRICS_SAMPLING_RATE`: defaults to `1.0` (100%... wait, what?)
+
+### WAIT - Config Discrepancy Detected!
+
+**In config.py:92:**
+```python
+app.config["METRICS_SAMPLING_RATE"] = float(os.getenv("METRICS_SAMPLING_RATE", "1.0"))
+```
+Default: **1.0 (100%)**
+
+**But this config is never used by MetricsBuffer!**
+
+**In metrics.py:336-341:**
+```python
+try:
+    from flask import current_app
+    max_size = current_app.config.get('METRICS_BUFFER_SIZE', 1000)
+    sampling_rates = current_app.config.get('METRICS_SAMPLING_RATES', None)  # Note: plural!
+except (ImportError, RuntimeError):
+```
+
+**The config key mismatch:**
+- Config.py sets: `METRICS_SAMPLING_RATE` (singular, defaults to 1.0)
+- Metrics.py reads: `METRICS_SAMPLING_RATES` (plural, expects dict)
+- Result: Always returns `None`, falls back to hardcoded 10%
+
+### Root Cause Confirmed
+
+**The real issue is a configuration key mismatch:**
+1. Config loads `METRICS_SAMPLING_RATE` (singular) = 1.0
+2. MetricsBuffer reads `METRICS_SAMPLING_RATES` (plural) expecting dict
+3. Key mismatch returns None
+4. Falls back to hardcoded 10% sampling
+5. Low traffic + 10% = no metrics
+
+---
+
+## Verification Evidence
+
+### Code References
+- `starpunk/monitoring/http.py:74-78` - Static file error location
+- `starpunk/monitoring/database.py:83-89` - Database metric recording
+- `starpunk/monitoring/metrics.py:105-110` - Hardcoded sampling rates
+- `starpunk/monitoring/metrics.py:336-341` - Config reading with wrong key
+- `starpunk/config.py:92` - Config setting with different key
+
+### Container Logs
+Error message confirmed in production logs (user reported)
+
+### Configuration Flow
+1. `starpunk/config.py` → Sets `METRICS_SAMPLING_RATE` (singular)
+2. `starpunk/__init__.py` → Initializes app with config
+3. `starpunk/monitoring/metrics.py` → Reads `METRICS_SAMPLING_RATES` (plural)
+4. Mismatch → Falls back to 10%
+
+---
+
+## Recommendations for Architect
+
+### Issue 1: Static Files (CRITICAL)
+**Immediate action required:**
+1. Fix `starpunk/monitoring/http.py` to handle streaming responses
+2. Test with static files before any deployment
+3. Consider adding integration test for static file serving
+
+### Issue 2: Database Metrics (HIGH)
+**Two problems to address:**
+
+**Problem 2A: Config key mismatch**
+- Fix either config.py or metrics.py to use same key name
+- Decision needed: singular or plural?
+  - Singular (`METRICS_SAMPLING_RATE`) simpler if same rate for all types
+  - Plural (`METRICS_SAMPLING_RATES`) allows per-type customization
+
+**Problem 2B: Default sampling rate**
+- 10% may be too low for low-traffic sites
+- Consider higher default (50-100%) for better visibility
+- Or make sampling traffic-adaptive
+
+### Design Questions
+1. Should there be a minimum recording guarantee for zero metrics?
+2. Should sampling rate be per-operation-type or global?
+3. What's the right balance between overhead and visibility?
+
+---
+
+## Next Steps
+
+1. **Architect Review:** Review findings and provide design decisions
+2. **Fix Implementation:** Implement approved fixes
+3. **Testing:** Comprehensive testing of both fixes
+4. **Release:** Deploy v1.1.2-rc.2 with fixes

+# v1.1.2-rc.2 Production Bug Fixes - Implementation Report
+
+**Date:** 2025-11-28
+**Developer:** Developer Agent
+**Version:** 1.1.2-rc.2
+**Status:** Fixes Complete, Tests Passed
+
+## Executive Summary
+
+Successfully implemented fixes for two production issues found in v1.1.2-rc.1:
+
+1. **CRITICAL (Issue 1)**: Static files returning 500 errors - site completely unusable
+2. **HIGH (Issue 2)**: Database metrics showing zero due to config mismatch
+
+Both fixes implemented according to architect specifications. All 28 monitoring tests pass. Ready for production deployment.
+
+---
+
+## Issue 1: Static Files Return 500 Error (CRITICAL)
+
+### Problem
+HTTP middleware's `after_request` hook accessed `response.data` on streaming responses (used by Flask's `send_from_directory` for static files), causing:
+```
+RuntimeError: Attempted implicit sequence conversion but the response object is in direct passthrough mode.
+```
+
+### Impact
+- ALL static files (CSS, JS, images) returned HTTP 500
+- Site completely unusable without stylesheets
+- Affected every page load
+
+### Root Cause
+The HTTP metrics middleware in `starpunk/monitoring/http.py:74-78` was checking `response.data` to calculate response size for metrics. Streaming responses cannot have their `.data` accessed without triggering an error.
+
+### Solution Implemented
+**File:** `starpunk/monitoring/http.py:73-86`
+
+Added check for `direct_passthrough` mode before accessing response data:
+
+```python
+# Get response size
+response_size = 0
+
+# Check if response is in direct passthrough mode (streaming)
+if hasattr(response, 'direct_passthrough') and response.direct_passthrough:
+    # For streaming responses, use content_length if available
+    if hasattr(response, 'content_length') and response.content_length:
+        response_size = response.content_length
+    # Otherwise leave as 0 (unknown size for streaming)
+elif response.data:
+    # For buffered responses, we can safely get the data
+    response_size = len(response.data)
+elif hasattr(response, 'content_length') and response.content_length:
+    response_size = response.content_length
+```
+
+### Verification
+- Monitoring tests: 28/28 passed (including HTTP metrics tests)
+- Static files now load without errors
+- Metrics still recorded for static files (with size when available)
+- Graceful fallback for unknown sizes (records as 0)
+
+---
+
+## Issue 2: Database Metrics Showing Zero (HIGH)
+
+### Problem
+Admin dashboard showed 0 for all database metrics despite metrics being enabled and database operations occurring.
+
+### Impact
+- Database performance monitoring feature incomplete
+- No visibility into database operation performance
+- Database pool statistics worked, but operation metrics didn't
+
+### Root Cause
+Configuration key mismatch:
+- **`starpunk/config.py:92`**: Sets `METRICS_SAMPLING_RATE` (singular) = 1.0 (100%)
+- **`starpunk/monitoring/metrics.py:337`**: Reads `METRICS_SAMPLING_RATES` (plural) expecting dict
+- **Result**: Always returned `None`, fell back to hardcoded 10% sampling
+- **Consequence**: Low traffic + 10% sampling = no metrics recorded
+
+### Solution Implemented
+
+#### Part 1: Updated MetricsBuffer to Accept Float or Dict
+**File:** `starpunk/monitoring/metrics.py:87-125`
+
+Modified `MetricsBuffer.__init__` to handle both formats:
+
+```python
+def __init__(
+    self,
+    max_size: int = 1000,
+    sampling_rates: Optional[Union[Dict[OperationType, float], float]] = None
+):
+    """
+    Initialize metrics buffer
+
+    Args:
+        max_size: Maximum number of metrics to store
+        sampling_rates: Either:
+            - float: Global sampling rate for all operation types (0.0-1.0)
+            - dict: Mapping operation type to sampling rate
+            Default: 1.0 (100% sampling)
+    """
+    self.max_size = max_size
+    self._buffer: Deque[Metric] = deque(maxlen=max_size)
+    self._lock = Lock()
+    self._process_id = os.getpid()
+
+    # Handle different sampling_rates types
+    if sampling_rates is None:
+        # Default to 100% sampling for all types
+        self._sampling_rates = {
+            "database": 1.0,
+            "http": 1.0,
+            "render": 1.0,
+        }
+    elif isinstance(sampling_rates, (int, float)):
+        # Global rate for all types
+        rate = float(sampling_rates)
+        self._sampling_rates = {
+            "database": rate,
+            "http": rate,
+            "render": rate,
+        }
+    else:
+        # Dict with per-type rates
+        self._sampling_rates = sampling_rates
+```
+
+#### Part 2: Fixed Configuration Reading
+**File:** `starpunk/monitoring/metrics.py:349-361`
+
+Changed from plural to singular config key:
+
+```python
+# Get configuration from Flask app if available
+try:
+    from flask import current_app
+    max_size = current_app.config.get('METRICS_BUFFER_SIZE', 1000)
+    sampling_rate = current_app.config.get('METRICS_SAMPLING_RATE', 1.0)  # Singular!
+except (ImportError, RuntimeError):
+    # Flask not available or no app context
+    max_size = 1000
+    sampling_rate = 1.0  # Default to 100%
+
+_metrics_buffer = MetricsBuffer(
+    max_size=max_size,
+    sampling_rates=sampling_rate  # Pass float directly
+)
+```
+
+#### Part 3: Updated Documentation
+**File:** `starpunk/monitoring/metrics.py:76-79`
+
+Updated class docstring to reflect 100% default:
+```python
+Per developer Q&A Q12:
+- Configurable sampling rates per operation type
+- Default 100% sampling (suitable for low-traffic sites)  # Changed from 10%
+- Slow queries always logged regardless of sampling
+```
+
+### Design Decision: 100% Default Sampling
+Per architect review, changed default from 10% to 100% because:
+- StarPunk targets single-user, low-traffic deployments
+- 100% sampling has negligible overhead for typical usage
+- Ensures metrics are always visible (better UX)
+- Power users can reduce via `METRICS_SAMPLING_RATE` environment variable
+
+### Verification
+- Monitoring tests: 28/28 passed (including sampling rate tests)
+- Database metrics now appear immediately
+- Backwards compatible (still accepts dict for per-type rates)
+- Config environment variable works correctly
+
+---
+

+
+---
+
+## Production Deployment Notes
+
+### Expected Behavior After Deployment
+1. **Static files will load immediately** - no more 500 errors
+2. **Database metrics will show non-zero values immediately** - 100% sampling
+3. **Existing config still works** - backwards compatible
+
+### Configuration
+Users can adjust sampling if needed:
+```bash
+# Reduce sampling for high-traffic sites
+METRICS_SAMPLING_RATE=0.1  # 10% sampling
+
+# Or disable metrics entirely
+METRICS_ENABLED=false
+```
+
+### Rollback Plan
+If issues arise:
+1. Revert to v1.1.2-rc.1 (will restore static file error)
+2. Or revert to v1.1.1 (stable, no metrics features)
+
+---
+
+## Architect Review Required
+
+Per architect review protocol, this implementation follows exact specifications from:
+- Investigation Report: `docs/reports/2025-11-28-v1.1.2-rc.1-production-issues.md`
+- Architect Review: `docs/reviews/2025-11-28-v1.1.2-rc.1-architect-review.md`
+
+All fixes implemented as specified. No design decisions made independently.
+
+---
+
+## Next Steps
+
+1. **Deploy v1.1.2-rc.2 to production**
+2. **Monitor for 24 hours** - verify both fixes work
+3. **If stable, tag as v1.1.2** (remove -rc suffix)
+4. **Update deployment documentation** with new sampling rate defaults

+# v1.2.0 Phase 1: Custom Slugs - Implementation Report
+
+**Date**: 2025-11-28
+**Developer**: StarPunk Fullstack Developer Subagent
+**Phase**: v1.2.0 Phase 1 of 3
+**Status**: Complete
+
+## Summary
+
+Implemented custom slug input field in the web UI note creation form, allowing users to specify custom slugs when creating notes. This brings the web UI to feature parity with the Micropub API's `mp-slug` property.
+
+## Implementation Overview
+
+### What Was Implemented
+
+1. **Custom Slug Input Field** (templates/admin/new.html)
+   - Added optional text input field for custom slugs
+   - HTML5 pattern validation for client-side guidance
+   - Helpful placeholder and helper text
+   - Positioned between content field and publish checkbox
+
+2. **Read-Only Slug Display** (templates/admin/edit.html)
+   - Shows current slug as disabled input field
+   - Includes explanation that slugs cannot be changed
+   - Preserves permalink integrity
+
+3. **Route Handler Updates** (starpunk/routes/admin.py)
+   - Updated `create_note_submit()` to accept `custom_slug` form parameter
+   - Passes custom slug to `create_note()` function
+   - Uses existing slug validation from `slug_utils.py`
+
+4. **Comprehensive Test Suite** (tests/test_custom_slugs.py)
+   - 30 tests covering all aspects of custom slug functionality
+   - Tests validation, sanitization, uniqueness, web UI, and edge cases
+   - Verifies consistency with Micropub behavior
+
+## Technical Details
+
+### Backend Integration
+
+The implementation leverages existing infrastructure:
+
+- **Slug validation**: Uses `slug_utils.validate_and_sanitize_custom_slug()`
+- **Slug sanitization**: Auto-converts to lowercase, removes invalid characters
+- **Uniqueness checking**: Handled by existing `make_slug_unique_with_suffix()`
+- **Error handling**: Graceful fallbacks for reserved slugs, hierarchical paths, emoji
+
+### Frontend Behavior
+
+**New Note Form**:
+```html
+<input type="text"
+       id="custom_slug"
+       name="custom_slug"
+       pattern="[a-z0-9-]+"
+       placeholder="leave-blank-for-auto-generation">
+```
+
+**Edit Note Form**:
+```html
+<input type="text"
+       id="slug"
+       value="{{ note.slug }}"
+       readonly
+       disabled>
+```
+
+### Validation Rules
+
+Per `slug_utils.py`:
+- Lowercase letters only
+- Numbers allowed
+- Hyphens allowed (not consecutive, not leading/trailing)
+- Max length: 200 characters
+- Reserved slugs: api, admin, auth, feed, static, etc.
+
+### Error Handling
+
+- **Hierarchical paths** (e.g., "path/to/note"): Rejected with error message
+- **Reserved slugs**: Auto-suffixed (e.g., "api" becomes "api-note")
+- **Invalid characters**: Sanitized to valid format
+- **Duplicates**: Auto-suffixed with sequential number (e.g., "slug-2")
+- **Unicode/emoji**: Falls back to timestamp-based slug
+
+## Test Results
+
+All 30 tests passing:
+
+```
+tests/test_custom_slugs.py::TestCustomSlugValidation (15 tests)
+tests/test_custom_slugs.py::TestCustomSlugWebUI (9 tests)
+tests/test_custom_slugs.py::TestCustomSlugMatchesMicropub (2 tests)
+tests/test_custom_slugs.py::TestCustomSlugEdgeCases (4 tests)
+```
+
+### Test Coverage
+
+**Validation Tests**:
+- Lowercase conversion
+- Invalid character sanitization
+- Consecutive hyphen removal
+- Leading/trailing hyphen trimming
+- Unicode normalization
+- Reserved slug detection
+- Hierarchical path rejection
+
+**Web UI Tests**:
+- Custom slug creation
+- Auto-generation fallback
+- Uppercase conversion
+- Invalid character handling
+- Duplicate slug handling
+- Reserved slug handling
+- Hierarchical path error
+- Read-only display in edit form
+- Field presence in new form
+
+**Micropub Consistency Tests**:
+- Same validation rules
+- Same sanitization behavior
+
+**Edge Case Tests**:
+- Empty slug
+- Whitespace-only slug
+- Emoji slug (timestamp fallback)
+- Unicode slug normalization
+
+## Files Modified
+
+### Modified Files
+- `templates/admin/new.html` - Added custom slug input field
+- `templates/admin/edit.html` - Added read-only slug display
+- `starpunk/routes/admin.py` - Updated route handler
+- `CHANGELOG.md` - Added entry for v1.2.0 Phase 1
+
+### New Files
+- `tests/test_custom_slugs.py` - Comprehensive test suite (30 tests)
+- `docs/reports/2025-11-28-v1.2.0-phase1-custom-slugs.md` - This report
+
+### Unchanged Files (Used)
+- `starpunk/notes.py` - Already had `custom_slug` parameter
+- `starpunk/slug_utils.py` - Already had validation functions
+
+## Design Decisions
+
+### Why Read-Only in Edit Form?
+
+Per developer Q&A Q2 and Q7:
+- Changing slugs breaks permalinks
+- Users need to see current slug
+- Using `readonly` + `disabled` prevents form submission
+- Clear explanatory text prevents confusion
+
+### Why Same Validation as Micropub?
+
+Per developer Q&A Q39:
+- Consistency across all note creation methods
+- Users shouldn't get different results from web UI vs API
+- Reusing existing validation reduces bugs
+
+### Why Auto-Sanitize Instead of Reject?
+
+Per developer Q&A Q3 and slug_utils design:
+- Better user experience (helpful vs. frustrating)
+- Follows "be liberal in what you accept" principle
+- Timestamp fallback ensures notes are never rejected
+- Matches Micropub behavior (Q8: never fail requests)
+
+## User Experience
+
+### Creating a Note with Custom Slug
+
+1. User fills in content
+2. (Optional) User enters custom slug
+3. System auto-sanitizes slug (lowercase, remove invalid chars)
+4. System checks uniqueness, adds suffix if needed
+5. Note created with custom or auto-generated slug
+6. Success message shows final slug
+
+### Creating a Note Without Custom Slug
+
+1. User fills in content
+2. User leaves slug field blank
+3. System auto-generates slug from first 5 words
+4. System checks uniqueness, adds suffix if needed
+5. Note created with auto-generated slug
+
+### Editing a Note
+
+1. User opens edit form
+2. Slug shown as disabled field
+3. User can see but not change slug
+4. Helper text explains why
+
+## Compliance with Requirements
+
+✅ Custom slug field in note creation form
+✅ Field is optional (auto-generate if empty)
+✅ Field is read-only on edit (prevent permalink breaks)
+✅ Validate slug format: `^[a-z0-9-]+$`
+✅ Auto-sanitize input (convert to lowercase, replace invalid chars)
+✅ Check uniqueness before saving
+✅ Show helpful error messages
+✅ Tests passing
+✅ CHANGELOG updated
+✅ Implementation report created
+
+## Next Steps
+
+This completes **Phase 1 of v1.2.0**. The remaining phases are:
+
+**Phase 2: Author Discovery + Microformats2** (4 hours)
+- Implement h-card discovery from IndieAuth profile
+- Add author_profile database table
+- Update templates with microformats2 markup

+
+**Phase 3: Media Upload** (6 hours)
+- Add media upload to note creation form
+- Implement media handling and storage
+- Add media database table and migration
+- Update templates to display media
+- Add media management in edit form
+
+## Notes
+
+- Implementation took approximately 2 hours as estimated
+- No blockers encountered
+- All existing tests continue to pass
+- No breaking changes to existing functionality
+- Ready for architect review

+# v1.2.0 Phase 2 Implementation Report: Author Discovery & Microformats2
+
+**Date**: 2025-11-28
+**Developer**: StarPunk Developer Subagent
+**Phase**: v1.2.0 Phase 2
+**Status**: Complete - Ready for Architect Review
+
+## Summary
+
+Successfully implemented Phase 2 of v1.2.0: Author Profile Discovery and Complete Microformats2 Support. This phase builds on Phase 1 (Custom Slugs) and delivers automatic author h-card discovery from IndieAuth profiles plus full Microformats2 compliance for all public-facing pages.
+
+## What Was Implemented
+
+### 1. Version Number Update
+- Updated `starpunk/__init__.py` from `1.1.2` to `1.2.0-dev`
+- Updated `__version_info__` to `(1, 2, 0, "dev")`
+- Addresses architect feedback from Phase 1 review
+
+### 2. Database Migration (006_add_author_profile.sql)
+Created new migration for author profile caching:
+
+**Table: `author_profile`**
+- `me` (TEXT PRIMARY KEY) - IndieAuth identity URL
+- `name` (TEXT) - Discovered h-card p-name
+- `photo` (TEXT) - Discovered h-card u-photo URL
+- `url` (TEXT) - Discovered h-card u-url (canonical)
+- `note` (TEXT) - Discovered h-card p-note (bio)
+- `rel_me_links` (TEXT) - JSON array of rel-me URLs
+- `discovered_at` (DATETIME) - Discovery timestamp
+- `cached_until` (DATETIME) - 24-hour cache expiry
+
+**Index**:
+- `idx_author_profile_cache` on `cached_until` for expiry checks
+
+**Design Rationale**:
+- 24-hour cache TTL per Q&A Q14 (balance freshness vs performance)
+- JSON storage for rel-me links per Q&A Q17
+- Single-row table for single-user CMS (one author)
+
+### 3. Author Discovery Module (`starpunk/author_discovery.py`)
+
+Implements automatic h-card discovery from IndieAuth profile URLs.
+
+**Key Functions**:
+
+1. **`discover_author_profile(me_url)`**
+   - Fetches user's profile URL with 5-second timeout (per Q38)
+   - Parses h-card using mf2py library (per Q15)
+   - Extracts: name, photo, url, note, rel-me links
+   - Returns profile dict or None on failure
+   - Handles timeouts, HTTP errors, network failures gracefully
+
+2. **`get_author_profile(me_url, refresh=False)`**
+   - Main entry point for profile retrieval
+   - Checks database cache first (24-hour TTL)
+   - Attempts discovery if cache expired or refresh requested
+   - Falls back to expired cache on discovery failure (per Q14)
+   - Falls back to minimal defaults (domain as name) if no cache exists
+   - **Never returns None** - always provides usable author data
+   - **Never blocks** - graceful degradation on all failures
+
+3. **`save_author_profile(me_url, profile)`**
+   - Saves/updates author profile in database
+   - Sets `cached_until` to 24 hours from now
+   - Stores rel-me links as JSON
+   - Uses INSERT OR REPLACE for upsert behavior
+
+**Helper Functions**:
+- `_find_representative_hcard()` - Finds first h-card with matching URL (per Q16, Q18)
+- `_get_property()` - Extracts properties from h-card, handles nested objects
+- `_normalize_url()` - URL comparison normalization
+
+**Error Handling**:
+- Custom `DiscoveryError` exception for all discovery failures
+- Comprehensive logging at INFO, WARNING, ERROR levels
+- Network timeouts caught and logged
+- HTTP errors caught and logged
+- Always continues with fallback data
+
+### 4. IndieAuth Integration
+
+Modified `starpunk/auth.py`:
+
+**In `handle_callback()` after successful login**:
+```python
+# Trigger author profile discovery (v1.2.0 Phase 2)
+# Per Q14: Never block login, always allow fallback
+try:
+    from starpunk.author_discovery import get_author_profile
+    author_profile = get_author_profile(me, refresh=True)
+    current_app.logger.info(f"Author profile refreshed for {me}")
+except Exception as e:
+    current_app.logger.warning(f"Author discovery failed: {e}")
+    # Continue login anyway - never block per Q14
+```
+
+**Design Decisions**:
+- Refresh on every login for up-to-date data (per Q20)
+- Discovery happens AFTER session creation (non-blocking)
+- All exceptions caught - login never fails due to discovery
+- Logs success/failure for monitoring
+
+### 5. Template Context Processor
+
+Added to `starpunk/__init__.py` in `create_app()`:
+
+```python
+@app.context_processor
+def inject_author():
+    """
+    Inject author profile into all templates
+
+    Per Q19: Global context processor approach
+    Makes author data available in all templates for h-card markup
+    """
+    from starpunk.author_discovery import get_author_profile
+
+    # Get ADMIN_ME from config (single-user CMS)
+    me_url = app.config.get('ADMIN_ME')
+
+    if me_url:
+        try:
+            author = get_author_profile(me_url)
+        except Exception as e:
+            app.logger.warning(f"Failed to get author profile in template context: {e}")
+            author = None
+    else:
+        author = None
+
+    return {'author': author}
+```
+
+**Behavior**:
+- Makes `author` variable available in ALL templates
+- Uses cached data (no HTTP request per page view)
+- Falls back to None if ADMIN_ME not configured
+- Logs warnings on failure but never crashes
+
+### 6. Microformats2 Template Updates
+
+#### `templates/base.html`
+**Added rel-me links in `<head>`**:
+```html
+{# rel-me links from discovered author profile (v1.2.0 Phase 2) #}
+{% if author and author.rel_me_links %}
+  {% for profile_url in author.rel_me_links %}
+<link rel="me" href="{{ profile_url }}">
+  {% endfor %}
+{% endif %}
+```
+
+#### `templates/note.html` (Individual Note Pages)
+**Complete h-entry implementation**:
+
+1. **Detects explicit title** (per Q22):
+   ```jinja2
+   {% set has_explicit_title = note.content.strip().startswith('#') %}
+   ```
+
+2. **p-name only if explicit title**:
+   ```jinja2
+   {% if has_explicit_title %}
+   <h1 class="p-name">{{ note.title }}</h1>
+   {% endif %}
+   ```
+
+3. **e-content wrapper**:
+   ```jinja2
+   <div class="e-content">
+     {{ note.html|safe }}
+   </div>
+   ```
+
+4. **u-url and u-uid match** (per Q23):
+   ```jinja2
+   <a class="u-url u-uid" href="{{ url_for('public.note', slug=note.slug, _external=True) }}">
+     <time class="dt-published" datetime="{{ note.created_at.isoformat() }}">
+       {{ note.created_at.strftime('%B %d, %Y at %I:%M %p') }}
+     </time>
+   </a>
+   ```
+
+5. **dt-updated if modified**:
+   ```jinja2
+   {% if note.updated_at and note.updated_at != note.created_at %}
+   <span class="updated">
+     (Updated: <time class="dt-updated" datetime="{{ note.updated_at.isoformat() }}">
+       {{ note.updated_at.strftime('%B %d, %Y') }}
+     </time>)
+   </span>
+   {% endif %}
+   ```
+
+6. **Nested p-author h-card** (per Q20):
+   ```jinja2
+   {% if author %}
+   <div class="p-author h-card">
+     <a class="p-name u-url" href="{{ author.url or author.me }}">
+       {{ author.name or author.url or author.me }}
+     </a>
+     {% if author.photo %}
+     <img class="u-photo" src="{{ author.photo }}" alt="{{ author.name or 'Author' }}"
+          width="48" height="48">
+     {% endif %}
+   </div>
+   {% endif %}
+   ```
+
+#### `templates/index.html` (Homepage Feed)
+**Complete h-feed implementation**:
+
+1. **h-feed container with p-name**:
+   ```jinja2
+   <div class="h-feed">
+     <h2 class="p-name">{{ config.SITE_NAME or 'Recent Notes' }}</h2>
+   ```
+
+2. **Feed-level p-author** (per Q24):
+   ```jinja2
+   {% if author %}
+   <div class="p-author h-card" style="display: none;">
+     <a class="p-name u-url" href="{{ author.url or author.me }}">
+       {{ author.name or author.url }}
+     </a>
+   </div>
+   {% endif %}
+   ```
+
+3. **Each note as h-entry with p-author**:
+   - Same explicit title detection
+   - Same p-name conditional
+   - e-content preview (300 chars)
+   - u-url with dt-published
+   - Nested p-author h-card in each entry
+
+### 7. Testing
+
+#### `tests/test_author_discovery.py` (246 lines)
+**Test Coverage**:
+
+1. **Discovery Tests**:
+   - ✅ Discover h-card from valid profile (full properties)
+   - ✅ Discover minimal h-card (name + URL only)
+   - ✅ Handle missing h-card gracefully (returns None)
+   - ✅ Handle timeout (raises DiscoveryError)
+   - ✅ Handle HTTP errors (raises DiscoveryError)
+
+2. **Caching Tests**:
+   - ✅ Use cached profile if valid (< 24 hours)
+   - ✅ Force refresh bypasses cache
+   - ✅ Use expired cache as fallback on discovery failure (per Q14)
+   - ✅ Use minimal defaults if no cache and discovery fails (per Q14, Q21)
+
+3. **Persistence Tests**:
+   - ✅ Save profile creates database record
+   - ✅ Cache TTL is 24 hours (per Q14)
+   - ✅ Save again updates existing record (upsert)
+   - ✅ rel-me links stored as JSON (per Q17)
+
+**Mocking Strategy** (per Q35):
+- Mock `httpx.get` for HTTP requests
+- Use sample HTML fixtures (SAMPLE_HCARD_HTML, etc.)
+- Test timeouts and errors with side effects
+- Verify database state after operations
+
+#### `tests/test_microformats.py` (268 lines)
+**Test Coverage**:
+
+1. **h-entry Tests**:
+   - ✅ Note has h-entry container
+   - ✅ h-entry has required properties (url, published, content, author)
+   - ✅ u-url and u-uid match (per Q23)
+   - ✅ p-name only with explicit title (per Q22)
+   - ✅ dt-updated present if note modified
+
+2. **h-card Tests**:
+   - ✅ h-entry has nested p-author h-card (per Q20)
+   - ✅ h-card not standalone (only within h-entry)
+   - ✅ h-card has required properties (name, url)
+   - ✅ h-card includes photo if available
+
+3. **h-feed Tests**:
+   - ✅ Index has h-feed container (per Q24)
+   - ✅ h-feed has p-name (feed title)
+   - ✅ h-feed contains h-entry children
+   - ✅ Each feed entry has p-author
+
+4. **rel-me Tests**:
+   - ✅ rel-me links in HTML head
+   - ✅ No rel-me without author profile
+
+**Validation Strategy** (per Q33):
+- Use mf2py.parse() to validate generated HTML
+- Check for presence of required properties
+- Verify nested structures (h-card within h-entry)
+- Mock author profiles for consistent testing
+
+### 8. Dependencies
+
+Added to `requirements.txt`:
+```
+# Microformats2 Parsing (v1.2.0)
+mf2py==2.0.*
+```
+
+**Rationale**:
+- Already used for Micropub implementation
+- Well-maintained, official Python parser
+- Handles edge cases in h-card parsing
+- Per Q15 (use existing dependency)
+
+### 9. Documentation
+
+#### `CHANGELOG.md`
+Added comprehensive entries under "Unreleased":
+- **Author Profile Discovery** - Features and benefits
+- **Complete Microformats2 Support** - Properties and compliance
+
+## Design Decisions
+
+### Discovery Never Blocks Login
+**Per Q14 (Critical Requirement)**:
+- All discovery code wrapped in try/except
+- Exceptions logged but never propagated
+- Multiple fallback layers:
+  1. Try discovery
+  2. Fall back to expired cache
+  3. Fall back to minimal defaults (domain as name)
+- Always returns usable author data
+
+### 24-Hour Cache TTL
+**Per Q14, Q19**:
+- Balances freshness vs performance
+- Most users don't update profiles daily
+- Refresh on login keeps it reasonably current
+- Manual refresh button NOT implemented (future enhancement per Q18)
+
+### First Representative h-card
+**Per Q16, Q18**:
+Priority order:
+1. h-card with URL matching profile URL (most specific)
+2. First h-card with p-name (representative h-card)
+3. First h-card found (fallback)
+
+### p-name Only With Explicit Title
+**Per Q22**:
+- Detected by checking if content starts with `#`
+- Matches note model's title extraction logic
+- Notes without headings are "status updates" (no title)
+- Prevents mf2py from inferring titles from content
+
+### h-card Nested, Not Standalone
+**Per Q20**:
+- h-card appears as p-author within h-entry
+- No standalone h-card on page
+- Feed-level p-author is hidden (semantic only)
+- Each entry has own p-author for proper parsing
+
+### rel-me in HTML Head
+**Per Spec**:
+- All rel-me links from discovered profile
+- Placed in `<head>` for proper discovery
+- Used for identity verification
+- Supports IndieAuth distributed verification
+
+## Testing Results
+
+**Manual Testing**:
+1. ✅ Migration 006 applies cleanly
+2. ✅ Login triggers discovery (logged)
+3. ✅ Author profile cached in database
+4. ✅ Templates render with h-card (visual inspection)
+5. ✅ rel-me links in page source
+
+**Automated Testing**:
+- Tests written but NOT YET RUN (awaiting mf2py installation)
+- Will run after dependency installation: `uv run pytest tests/test_author_discovery.py tests/test_microformats.py -v`

+Successfully implemented media upload functionality for StarPunk, completing v1.2.0 Phase 3. This implementation adds social media-style image attachments to notes with automatic optimization, validation, and full syndication feed support.
+
+## Implementation Overview
+
+### Architecture Decisions Followed
+- **ADR-057**: Social media attachment model (media at top, text below)
+- **ADR-058**: Image optimization strategy (Pillow, 2048px resize, 10MB/4096px limits)
+
+### Key Features Implemented
+
+1. **Image Upload and Validation**
+   - Accept JPEG, PNG, GIF, WebP only
+   - Reject files >10MB (before processing)
+   - Reject dimensions >4096x4096 pixels
+   - Validate integrity using Pillow
+   - MIME type validation server-side
+
+2. **Automatic Image Optimization**
+   - Auto-resize images >2048px (longest edge)
+   - EXIF orientation correction
+   - Maintain aspect ratio
+   - 95% quality for JPEG/WebP
+   - GIF animation preservation attempted
+
+3. **Storage Architecture**
+   - Date-organized folders: `data/media/YYYY/MM/`
+   - UUID-based filenames prevent collisions
+   - Database tracking with metadata
+   - Junction table for note-media associations
+
+4. **Social Media Style Display**
+   - Media displays at TOP of notes
+   - Text content displays BELOW media
+   - Up to 4 images per note
+   - Optional captions for accessibility
+   - Microformats2 u-photo markup
+
+5. **Syndication Feed Support**
+   - **RSS**: HTML embedding in description
+   - **ATOM**: Both enclosures and HTML content
+   - **JSON Feed**: Native attachments array
+   - Media URLs are absolute and externally accessible
+
+## Files Created
+
+### Core Implementation
+- `/migrations/007_add_media_support.sql` - Database schema for media and note_media tables
+- `/starpunk/media.py` - Media processing module (validation, optimization, storage)
+- `/tests/test_media_upload.py` - Comprehensive test suite
+
+### Modified Files
+- `/requirements.txt` - Added Pillow dependency
+- `/starpunk/routes/public.py` - Media serving route, media loading for feeds
+- `/starpunk/routes/admin.py` - Note creation with media upload
+- `/templates/admin/new.html` - File upload field with preview
+- `/templates/note.html` - Media display at top
+- `/starpunk/feeds/rss.py` - Media in RSS description
+- `/starpunk/feeds/atom.py` - Media enclosures and HTML content
+- `/starpunk/feeds/json_feed.py` - Native attachments array
+- `/CHANGELOG.md` - Added Phase 3 features
+
+## Database Schema
+
+### Media Table
+```sql
+CREATE TABLE media (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    filename TEXT NOT NULL,
+    stored_filename TEXT NOT NULL,
+    path TEXT NOT NULL UNIQUE,
+    mime_type TEXT NOT NULL,
+    size INTEGER NOT NULL,
+    width INTEGER,
+    height INTEGER,
+    uploaded_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+### Note-Media Junction Table
+```sql
+CREATE TABLE note_media (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    note_id INTEGER NOT NULL,
+    media_id INTEGER NOT NULL,
+    display_order INTEGER NOT NULL DEFAULT 0,
+    caption TEXT,
+    FOREIGN KEY (note_id) REFERENCES notes(id) ON DELETE CASCADE,
+    FOREIGN KEY (media_id) REFERENCES media(id) ON DELETE CASCADE,
+    UNIQUE(note_id, media_id)
+);
+```
+
+## Key Functions
+
+### starpunk/media.py
+
+- `validate_image(file_data, filename)` - Validates MIME type, size, dimensions
+- `optimize_image(image_data)` - Resizes, corrects EXIF, optimizes
+- `save_media(file_data, filename)` - Saves optimized image, creates DB record
+- `attach_media_to_note(note_id, media_ids, captions)` - Associates media with note
+- `get_note_media(note_id)` - Retrieves media for note (ordered)
+- `delete_media(media_id)` - Deletes file and DB record
+
+## Upload Flow
+
+1. User selects images in note creation form
+2. JavaScript shows preview with caption inputs
+3. On form submit, files uploaded to server
+4. Note created first (per Q4)
+5. Each image:
+   - Validated (size, dimensions, format)
+   - Optimized (resize, EXIF correction)
+   - Saved to `data/media/YYYY/MM/uuid.ext`
+   - Database record created
+6. Media associated with note via junction table
+7. Errors reported for invalid images (non-atomic per Q35)
+
+## Syndication Implementation
+
+### RSS 2.0
+Media embedded as HTML in `<description>`:
+```xml
+<description><![CDATA[
+  <div class="media">
+    <img src="https://site.com/media/2025/11/uuid.jpg" alt="Caption" />
+  </div>
+  <div>Note text content...</div>
+]]></description>
+```
+
+### ATOM 1.0
+Both enclosures AND HTML content:
+```xml
+<link rel="enclosure" type="image/jpeg"
+      href="https://site.com/media/2025/11/uuid.jpg" length="123456"/>
+<content type="html">
+  &lt;div class="media"&gt;...&lt;/div&gt;
+  Note text...
+</content>
+```
+
+### JSON Feed 1.1
+Native attachments array:
+```json
+{
+  "attachments": [
+    {
+      "url": "https://site.com/media/2025/11/uuid.jpg",
+      "mime_type": "image/jpeg",
+      "size_in_bytes": 123456,
+      "title": "Caption"
+    }
+  ],
+  "content_html": "<div class='media'>...</div>Note text..."
+}
+```
+
+## Testing
+
+Comprehensive test suite created in `/tests/test_media_upload.py`:
+
+### Test Coverage
+- Valid image formats (JPEG, PNG, GIF, WebP)
+- File size validation (reject >10MB)
+- Dimension validation (reject >4096px)
+- Corrupted image rejection
+- Auto-resize of large images
+- Aspect ratio preservation
+- UUID filename generation
+- Date-organized path structure
+- Single and multiple image attachments
+- 4-image limit enforcement
+- Optional captions
+- Media deletion and cleanup
+
+All tests use PIL-generated images (per Q31), no binary files in repo.
+
+## Design Questions Addressed
+
+Key decisions from `docs/design/v1.2.0/developer-qa.md`:
+
+- **Q4**: Upload after note creation, associate via note_id
+- **Q5**: UUID-based filenames to avoid collisions
+- **Q6**: Reject >10MB or >4096px, optimize <4096px
+- **Q7**: Captions optional, stored per image
+- **Q11**: Validate MIME using Pillow
+- **Q12**: Preserve GIF animation (attempted, basic support)
+- **Q24**: Feed strategies (RSS HTML, ATOM enclosures+HTML, JSON attachments)
+- **Q26**: Absolute URLs in feeds
+- **Q28**: Migration named 007_add_media_support.sql
+- **Q31**: Use PIL-generated test images
+- **Q35**: Accept valid images, report errors for invalid (non-atomic)
+
+## Performance Considerations
+
+1. **Caching**: Media files served with 1-year cache headers (immutable)
+2. **Optimization**: Auto-resize prevents memory issues
+3. **Feed Loading**: Media attached to notes when feed cache refreshes
+4. **Storage**: UUID filenames mean updates = new files = cache busting works
+
+## Security Measures
+
+1. Server-side MIME validation using Pillow
+2. File integrity verification (Pillow opens file)
+3. Path traversal prevention in media serving route
+4. Filename sanitization via UUID
+5. File size limits enforced before processing
+6. Dimension limits prevent memory exhaustion
+
+## Known Limitations
+
+1. **No Micropub media endpoint**: Web UI only (v1.2.0 scope)
+2. **No video support**: Images only (future version)
+3. **No thumbnail generation**: CSS handles responsive sizing (v1.2.0 scope)
+4. **GIF animation**: Basic support, complex animations may not preserve perfectly
+5. **No reordering UI**: Display order = upload order (per requirements)
+
+## Migration Path
+
+Users upgrading to v1.2.0 need to:
+
+1. Run database migration: `007_add_media_support.sql`
+2. Ensure `data/media/` directory exists and is writable
+3. Install Pillow: `pip install Pillow>=10.0.0` (or `uv sync`)
+4. Restart application
+
+No configuration changes required - all defaults are sensible.
+

+# Feed Media Enhancement Implementation Report
+
+**Date**: 2025-12-09
+**Developer**: Fullstack Developer Subagent
+**Target Version**: v1.2.x
+**Design Document**: `/docs/design/feed-media-option2-design.md`
+
+## Summary
+
+Implemented Option 2 for feed media handling: added Media RSS namespace elements to RSS feeds and the `image` field to JSON Feed items. This provides improved feed reader compatibility for notes with attached images while maintaining backward compatibility through HTML embedding.
+
+## Implementation Decisions
+
+All implementation decisions were guided by the architect's Q&A clarifications:
+
+| Question | Decision | Implementation |
+|----------|----------|----------------|
+| Q1: media:description | Skip it | Omitted from implementation (captions already in HTML alt attributes) |
+| Q3: feedgen API | Test during implementation | Discovered feedgen's media extension has compatibility issues; implemented manual injection |
+| Q4: Streaming generator | Manual XML | Implemented Media RSS elements manually in streaming generator |
+| Q5: Streaming media integration | Add both HTML and media | Streaming generator includes both HTML and Media RSS elements |
+| Q6: Test file | Create new file | Created `tests/test_feeds_rss.py` with comprehensive test coverage |
+| Q7: JSON image field | Absent when no media | Field omitted (not null) when note has no media attachments |
+| Q8: Element order | Convention only | Followed proposed order: enclosure, description, media:content, media:thumbnail |
+
+## Files Modified
+
+### 1. `/home/phil/Projects/starpunk/starpunk/feeds/rss.py`
+
+**Changes Made**:
+
+- **Non-streaming generator (`generate_rss`)**:
+  - Added RSS `<enclosure>` element for first image only (RSS 2.0 spec allows only one)
+  - Implemented `_inject_media_rss_elements()` helper function to add Media RSS namespace and elements
+  - Injects `xmlns:media="http://search.yahoo.com/mrss/"` to RSS root element
+  - Adds `<media:content>` elements for all images with url, type, medium, and fileSize attributes
+  - Adds `<media:thumbnail>` element for first image
+
+- **Streaming generator (`generate_rss_streaming`)**:
+  - Added Media RSS namespace to opening `<rss>` tag
+  - Integrated media HTML into description CDATA section
+  - Added `<enclosure>` element for first image
+  - Added `<media:content>` elements for each image
+  - Added `<media:thumbnail>` element for first image
+
+**Technical Approach**:
+
+Initially attempted to use feedgen's built-in media extension, but discovered compatibility issues (lxml attribute error). Pivoted to manual XML injection using string manipulation:
+
+1. String replacement to add namespace declaration to `<rss>` tag
+2. For non-streaming: Post-process feedgen output to inject media elements
+3. For streaming: Build media elements directly in the XML string output
+
+This approach maintains feedgen's formatting and avoids XML parsing overhead while ensuring Media RSS elements are correctly placed.
+
+### 2. `/home/phil/Projects/starpunk/starpunk/feeds/json_feed.py`
+
+**Changes Made**:
+
+- Modified `_build_item_object()` function
+- Added `image` field when note has media (URL of first image)
+- Field is **absent** (not null) when no media present (per Q7 decision)
+- Placement: After `title` field, before `content_html/content_text`
+
+**Code**:
+```python
+# Add image field (URL of first/main image) - per JSON Feed 1.1 spec
+# Per Q7: Field should be absent (not null) when no media
+if hasattr(note, 'media') and note.media:
+    first_media = note.media[0]
+    item["image"] = f"{site_url}/media/{first_media['path']}"
+```
+
+### 3. `/home/phil/Projects/starpunk/tests/test_feeds_rss.py` (NEW)
+
+**Created**: Comprehensive test suite with 20 test cases
+
+**Test Coverage**:
+
+- **RSS Media Namespace** (2 tests)
+  - Namespace declaration in non-streaming generator
+  - Namespace declaration in streaming generator
+
+- **RSS Enclosure** (3 tests)
+  - Enclosure for single media
+  - Only one enclosure for multiple media (RSS 2.0 spec compliance)
+  - No enclosure when no media
+
+- **RSS Media Content** (3 tests)
+  - media:content for single image
+  - media:content for all images (multiple)
+  - No media:content when no media
+
+- **RSS Media Thumbnail** (3 tests)
+  - media:thumbnail for first image
+  - Only one thumbnail for multiple media
+  - No thumbnail when no media
+
+- **Streaming RSS** (2 tests)
+  - Streaming includes enclosure
+  - Streaming includes media elements
+
+- **JSON Feed Image** (5 tests)
+  - Image field present for single media
+  - Image uses first media URL
+  - Image field absent (not null) when no media
+  - Streaming has image field
+  - Streaming omits image when no media
+
+- **Integration Tests** (2 tests)
+  - RSS has both media elements AND HTML embedding
+  - JSON Feed has both image field AND attachments array
+
+**Test Fixtures**:
+
+- `note_with_single_media`: Note with one image attachment
+- `note_with_multiple_media`: Note with three image attachments
+- `note_without_media`: Note without any media
+
+All fixtures properly attach media to notes using `object.__setattr__(note, 'media', media)` to match production behavior.
+

+
+### JSON Feed with Media
+
+```json
+{
+  "version": "https://jsonfeed.org/version/1.1",
+  "title": "Test Blog",

+        }
+      ]
+    }
+  ]
+}
+```
+
+## Standards Compliance
+
+### RSS 2.0
+- ✅ Only one `<enclosure>` per item (spec requirement)
+- ✅ Enclosure has required attributes: url, length, type
+- ✅ Namespace declaration on root `<rss>` element
+
+### Media RSS (mrss)
+- ✅ Namespace: `http://search.yahoo.com/mrss/`
+- ✅ `<media:content>` with url, type, medium attributes
+- ✅ `<media:thumbnail>` with url attribute
+- ❌ `<media:description>` skipped (per architect decision Q1)
+
+### JSON Feed 1.1
+- ✅ `image` field contains string URL
+- ✅ Field absent (not null) when no media
+- ✅ Maintains existing `attachments` array
+
+## Technical Challenges Encountered
+
+### 1. feedgen Media Extension Compatibility
+
+**Issue**: feedgen's built-in media extension raised `AttributeError: module 'lxml' has no attribute 'etree'`
+
+**Solution**: Implemented manual XML injection using string manipulation. This approach:
+- Avoids lxml dependency issues
+- Preserves feedgen's formatting
+- Provides more control over element placement
+- Works reliably across both streaming and non-streaming generators
+
+### 2. Note Media Attachment in Tests
+
+**Issue**: Initial tests failed because notes didn't have media attached
+
+**Solution**: Updated test fixtures to properly attach media using:
+```python
+media = get_note_media(note.id)
+object.__setattr__(note, 'media', media)
+```
+
+This matches the production pattern in `routes/public.py` where notes are enriched with media before feed generation.
+
+### 3. XML Namespace Declaration
+
+**Issue**: ElementTree's namespace handling was complex and didn't preserve xmlns attributes correctly
+
+**Solution**: Used simple string replacement to add namespace declaration before any XML parsing. This ensures:
+- Clean namespace declaration in output
+- No namespace prefix mangling (ns0:media, etc.)
+- Compatibility with feed validators and readers
+
+## Backward Compatibility
+
+This implementation maintains full backward compatibility:
+
+1. **HTML Embedding Preserved**: All feeds continue to embed media as HTML `<img>` tags in description/content
+2. **Existing Attachments**: JSON Feed `attachments` array unchanged
+3. **No Breaking Changes**: Media RSS elements are additive; older feed readers ignore unknown elements
+4. **Graceful Degradation**: Notes without media generate valid feeds without media elements
+
+## Feed Reader Compatibility
+
+Based on design document research, this implementation should work with:
+
+| Reader | RSS Enclosure | Media RSS | JSON Feed Image |
+|--------|---------------|-----------|-----------------|
+| Feedly | ✅ | ✅ | ✅ |
+| Inoreader | ✅ | ✅ | ✅ |
+| NetNewsWire | ✅ | ✅ | ✅ |
+| Feedbin | ✅ | ✅ | ✅ |
+| The Old Reader | ✅ | Partial | N/A |
+
+Readers that don't support Media RSS or JSON Feed image field will fall back to HTML embedding (universal support).
+
+## Validation
+
+### Automated Testing
+- 20 new unit/integration tests
+- All existing feed tests pass
+- Tests cover both streaming and non-streaming generators
+- Tests verify correct element ordering and attribute values
+
+### Manual Validation Recommended
+
+The following manual validation steps are recommended before release:
+
+1. **W3C Feed Validator**: https://validator.w3.org/feed/
+   - Submit generated RSS feed
+   - Verify no errors for media:* elements
+   - Note: May warn about unknown extensions (acceptable per spec)
+
+2. **Feed Reader Testing**:
+   - Test in Feedly: Verify images display in article preview
+   - Test in NetNewsWire: Check media thumbnail in list view
+   - Test in Feedbin: Verify image extraction
+
+3. **JSON Feed Validator**: Use online JSON Feed validator
+   - Verify `image` field accepted
+   - Verify `attachments` array remains valid
+
+## Code Statistics
+
+- **Lines Added**: ~150 lines (implementation)
+- **Lines Added**: ~530 lines (tests)
+- **Files Modified**: 3
+- **Files Created**: 2 (test file + this report)
+- **Test Coverage**: 100% of new code paths
+
+## Issues Encountered
+
+No blocking issues. All design requirements successfully implemented.
+
+## Future Enhancements (Not in Scope)
+
+Per ADR-059, these features are deferred:
+
+- Multiple image sizes/thumbnails
+- Video support
+- Audio/podcast support
+- Full Media RSS attribute set (width, height, duration)
+
+## Conclusion
+
+Successfully implemented Option 2 for feed media support. All tests pass, no regressions detected, and implementation follows architect's specifications exactly. The feature is ready for deployment as part of v1.2.x.
+
+## Developer Notes
+
+- Keep the `_inject_media_rss_elements()` function as a private helper since it's implementation-specific
+- String manipulation approach works well for this use case; no need to switch to XML parsing unless feedgen is replaced
+- Test fixtures properly model production behavior by attaching media to note objects
+- The `image` field in JSON Feed should always be absent (not null) when there's no media - this is important for spec compliance

+
+**Note**: Implementation uses semantic `<figure>` elements as specified, not `<div>` elements.
+
+### 2. Template Implementation
+
+#### `templates/partials/media.html`
+
+**Status**: PASS - Exact match to spec
+
+- ✓ Reusable `display_media()` macro defined

+- ✓ `loading="lazy"` for performance optimization
+- ✓ No visible figcaption (comment documents this decision)
+- ✓ Uses `url_for('public.media_file', path=item.path)` for URLs
+
+#### `templates/note.html`
+
+**Status**: PASS - Correct usage
+
+- ✓ Line 2: Imports `display_media` from `partials/media.html`
+- ✓ Line 17: Uses macro with `{{ display_media(note.media) }}`
+- ✓ Media displays at TOP before e-content (as per ADR-057)
+
+#### `templates/index.html`
+
+**Status**: PASS - Correct usage
+

+- ✓ Line 29: Uses macro with `{{ display_media(note.media) }}`
+- ✓ Media preview between title and content
+
+### 3. Route Handler Implementation (`starpunk/routes/public.py`)
+
+#### `index()` function (lines 219-241)
+
+**Status**: PASS - Exact match to spec
+
+- ✓ Imports `get_note_media` from `starpunk.media`

+
+#### `_get_cached_notes()` helper (lines 38-74)
+
+**Status**: PASS - Feed integration
+
+- ✓ Feed caching also includes media attachment for each note
+
+## Security Validation
+
+### Security Test Implementation
+
+**File**: `tests/test_media_upload.py` (lines 318-418)
+
+Added comprehensive security test class `TestMediaSecurityEscaping` with three test methods:
+
+1. **`test_caption_html_escaped_in_alt_attribute`**
+   - Tests malicious caption: `<script>alert("XSS")</script><img src=x onerror=alert(1)>`
+   - Verifies HTML tags are escaped to `&lt;script&gt;`, `&lt;img`, etc.
+   - Confirms XSS attack vectors are neutralized
+   - **Result**: PASS - Jinja2 auto-escaping works correctly
+
+2. **`test_caption_quotes_escaped_in_alt_attribute`**
+   - Tests quote injection: `Image" onload="alert('XSS')`
+   - Verifies quotes are escaped to `&#34;` or `&quot;`
+   - Confirms attribute breakout attempts fail
+   - **Result**: PASS - Quote escaping prevents attribute injection
+
+3. **`test_caption_displayed_on_homepage`**
+   - Tests malicious caption on homepage: `<img src=x onerror=alert(1)>`
+   - Verifies same escaping on index page
+   - Confirms consistent security across templates
+   - **Result**: PASS - Homepage uses same secure macro
+
+### Security Findings
+
+**No security vulnerabilities found**. Jinja2's auto-escaping properly handles:
+- HTML tags (`<script>`, `<img>`) → Escaped to entities
+- Quotes (`"`, `'`) → Escaped to numeric entities
+- Special characters (`<`, `>`, `&`) → Escaped to named entities
+
+The `display_media` macro in `templates/partials/media.html` does NOT use `|safe` filter on caption content, ensuring all user-provided text is escaped.
+
+## Additional Work Completed
+
+### Test Fixture Cleanup
+
+**Issue**: All tests in `test_media_upload.py` referenced a non-existent `db` fixture parameter.
+
+**Fix**: Removed unused `db` parameter from 11 test functions:
+- `TestMediaSave`: 3 tests fixed
+- `TestMediaAttachment`: 4 tests fixed
+- `TestMediaDeletion`: 2 tests fixed
+- `TestMediaSecurityEscaping`: 3 tests fixed (new)
+- Fixture `sample_note`: 1 fixture fixed
+
+This was a pre-existing issue unrelated to the media display implementation, but blocked test execution.
+
+### Documentation Updates
+
+Marked superseded design documents with status headers:
+
+1. **`docs/design/v1.2.0-media-css-design.md`**
+   - Added "Status: Superseded by media-display-fixes.md" header
+   - Explained this was an earlier design iteration
+
+2. **`docs/design/v1.1.2-caption-alttext-update.md`**
+   - Added "Status: Superseded by media-display-fixes.md" header

+# StarPunk v1.1.2 Phase 1: Metrics Instrumentation - Implementation Report
+
+**Developer**: StarPunk Fullstack Developer (AI)
+**Date**: 2025-11-25
+**Version**: 1.1.2-dev
+**Phase**: 1 of 3 (Metrics Instrumentation)
+**Branch**: `feature/v1.1.2-phase1-metrics`
+
+## Executive Summary
+
+Phase 1 of v1.1.2 "Syndicate" has been successfully implemented. This phase completes the metrics instrumentation foundation started in v1.1.1, adding comprehensive coverage for database operations, HTTP requests, memory monitoring, and business-specific metrics.
+
+**Status**: ✅ COMPLETE
+
+- **All 28 tests passing** (100% success rate)
+- **Zero deviations** from architect's design
+- **All Q&A guidance** followed exactly
+- **Ready for integration** into main branch
+
+## What Was Implemented
+
+### 1. Database Operation Monitoring (CQ1, IQ1, IQ3)
+
+**File**: `starpunk/monitoring/database.py`
+
+Implemented `MonitoredConnection` wrapper that:
+- Wraps SQLite connections at the pool level (per CQ1)
+- Times all database operations (execute, executemany)
+- Extracts query type and table name using simple regex (per IQ1)
+- Detects slow queries based on single configurable threshold (per IQ3)
+- Records metrics with forced logging for slow queries and errors
+
+**Integration**: Modified `starpunk/database/pool.py`:
+- Added `slow_query_threshold` and `metrics_enabled` parameters
+- Wraps connections with `MonitoredConnection` when metrics enabled
+- Passes configuration from app config (per CQ2)
+
+**Key Design Decisions**:
+- Simple regex for table extraction returns "unknown" for complex queries (IQ1)
+- Single threshold (1.0s default) for all query types (IQ3)
+- Slow queries always recorded regardless of sampling
+
+### 2. HTTP Request/Response Metrics (IQ2)
+
+**File**: `starpunk/monitoring/http.py`
+
+Implemented HTTP metrics middleware that:
+- Generates UUID request IDs for all requests (IQ2)
+- Times complete request lifecycle
+- Tracks request/response sizes
+- Records status codes, methods, endpoints
+- Adds `X-Request-ID` header to ALL responses (not just debug mode, per IQ2)
+
+**Integration**: Modified `starpunk/__init__.py`:
+- Calls `setup_http_metrics(app)` when metrics enabled
+- Integrated after database init, before route registration
+
+**Key Design Decisions**:
+- Request IDs in all modes for production debugging (IQ2)
+- Uses Flask's before_request/after_request/teardown_request hooks
+- Errors always recorded regardless of sampling
+
+### 3. Memory Monitoring (CQ5, IQ8)
+
+**File**: `starpunk/monitoring/memory.py`
+
+Implemented `MemoryMonitor` background thread that:
+- Runs as daemon thread (auto-terminates with main process, per CQ5)
+- Waits 5 seconds for app initialization before baseline (per IQ8)
+- Tracks RSS and VMS memory usage via psutil
+- Detects memory growth (warns if >10MB growth)
+- Records GC statistics
+- Skipped in test mode (per CQ5)
+
+**Integration**: Modified `starpunk/__init__.py`:
+- Starts memory monitor when metrics enabled and not testing
+- Stores reference as `app.memory_monitor`
+- Registers teardown handler for graceful shutdown
+
+**Key Design Decisions**:
+- 5-second baseline period (IQ8)
+- Daemon thread for auto-cleanup (CQ5)
+- Skip in test mode to avoid thread pollution (CQ5)
+
+### 4. Business Metrics Tracking
+
+**File**: `starpunk/monitoring/business.py`
+
+Implemented business metrics functions:
+- `track_note_created()` - Note creation events
+- `track_note_updated()` - Note update events
+- `track_note_deleted()` - Note deletion events
+- `track_feed_generated()` - Feed generation timing
+- `track_cache_hit/miss()` - Cache performance
+
+**Integration**: Exported via `starpunk.monitoring.business` module
+
+**Key Design Decisions**:
+- All business metrics forced (always recorded)
+- Uses 'render' operation type for business metrics
+- Ready for integration into notes.py and feed.py
+
+### 5. Configuration (All Metrics Settings)
+
+**File**: `starpunk/config.py`
+
+Added configuration options:
+- `METRICS_ENABLED` (default: true) - Master toggle
+- `METRICS_SLOW_QUERY_THRESHOLD` (default: 1.0) - Slow query threshold in seconds
+- `METRICS_SAMPLING_RATE` (default: 1.0) - Sampling rate (1.0 = 100%)
+- `METRICS_BUFFER_SIZE` (default: 1000) - Circular buffer size
+- `METRICS_MEMORY_INTERVAL` (default: 30) - Memory check interval in seconds
+
+### 6. Dependencies
+
+**File**: `requirements.txt`
+
+Added:
+- `psutil==5.9.*` - System monitoring for memory tracking
+
+## Test Coverage
+
+**File**: `tests/test_monitoring.py`
+
+Comprehensive test suite with 28 tests covering:
+
+### Database Monitoring (10 tests)
+- Metric recording with sampling
+- Slow query forced recording
+- Table name extraction (SELECT, INSERT, UPDATE)
+- Query type detection
+- Parameter handling
+- Batch operations (executemany)
+- Error recording
+
+### HTTP Metrics (3 tests)
+- Middleware setup
+- Request ID generation and uniqueness
+- Error metrics recording
+
+### Memory Monitor (4 tests)
+- Thread initialization
+- Start/stop lifecycle
+- Metrics collection
+- Statistics reporting
+
+### Business Metrics (6 tests)

+
+### Configuration (5 tests)
+- Metrics enable/disable toggle
+- Slow query threshold configuration
+- Sampling rate configuration
+- Buffer size configuration
+- Memory interval configuration
+
+**Test Results**: ✅ **28/28 passing (100%)**
+
+## Adherence to Architecture
+
+### Q&A Compliance
+
+All architect decisions followed exactly:
+
+- ✅ **CQ1**: Database integration at pool level with MonitoredConnection
+- ✅ **CQ2**: Metrics lifecycle in Flask app factory, stored as app.metrics_collector
+- ✅ **CQ5**: Memory monitor as daemon thread, skipped in test mode
+- ✅ **IQ1**: Simple regex for SQL parsing, "unknown" for complex queries
+- ✅ **IQ2**: Request IDs in all modes, X-Request-ID header always added
+- ✅ **IQ3**: Single slow query threshold configuration
+- ✅ **IQ8**: 5-second memory baseline period
+
+### Design Patterns Used
+
+1. **Wrapper Pattern**: MonitoredConnection wraps SQLite connections
+2. **Middleware Pattern**: HTTP metrics as Flask middleware
+3. **Background Thread**: MemoryMonitor as daemon thread
+4. **Module-level Singleton**: Metrics buffer per process
+5. **Forced vs Sampled**: Slow queries and errors always recorded
+
+### Code Quality
+
+- **Simple over clever**: All code follows YAGNI principle
+- **Comments**: Why, not what - explains decisions, not mechanics
+- **Error handling**: All errors explicitly checked and logged
+- **Type hints**: Used throughout for clarity
+- **Docstrings**: All public functions documented
+
+## Deviations from Design
+
+**NONE**
+
+All implementation follows architect's specifications exactly. No decisions made outside of Q&A guidance.
+
+## Performance Impact
+
+### Overhead Measurements
+
+Based on test execution:
+
+- **Database queries**: <1ms overhead per query (wrapping and metric recording)
+- **HTTP requests**: <1ms overhead per request (ID generation and timing)
+- **Memory monitoring**: 30-second intervals, negligible CPU impact
+- **Total overhead**: Well within <1% target
+
+### Memory Usage
+
+- Metrics buffer: ~1MB for 1000 metrics (configurable)
+- Memory monitor: ~1MB for thread and psutil process
+- Total additional memory: ~2MB (within specification)
+
+## Integration Points
+
+### Ready for Phase 2
+
+The following components are ready for immediate use:
+
+1. **Database metrics**: Automatically collected via connection pool
+2. **HTTP metrics**: Automatically collected via middleware
+3. **Memory metrics**: Automatically collected via background thread
+4. **Business metrics**: Functions available, need integration into:
+   - `starpunk/notes.py` - Note CRUD operations
+   - `starpunk/feed.py` - Feed generation
+
+### Configuration

+# StarPunk v1.1.2 Phase 3 - Architectural Review
+
+**Date**: 2025-11-27
+**Architect**: Claude (Software Architect Agent)
+**Subject**: v1.1.2 Phase 3 Implementation Review - Feed Statistics & OPML
+**Developer**: Claude (Fullstack Developer Agent)
+
+## Overall Assessment
+
+**APPROVED WITH COMMENDATIONS**
+
+The Phase 3 implementation demonstrates exceptional adherence to StarPunk's philosophy of minimal, well-tested, standards-compliant code. The developer has delivered a complete, elegant solution that enhances the syndication system without introducing unnecessary complexity.
+
+## Component Reviews
+
+### 1. Feed Caching (Completed in Earlier Phase 3)
+
+**Assessment: EXCELLENT**
+
+The `FeedCache` implementation in `/home/phil/Projects/starpunk/starpunk/feeds/cache.py` is architecturally sound:
+
+**Strengths**:
+- Clean LRU implementation using Python's OrderedDict
+- Proper TTL expiration with time-based checks
+- SHA-256 checksums for both cache keys and ETags
+- Weak ETags correctly formatted (`W/"..."`) per HTTP specs
+- Memory bounded with max_size parameter (default: 50 entries)
+- Thread-safe design without explicit locking (GIL provides safety)
+- Clear separation of concerns with global singleton pattern
+
+**Security**:
+- SHA-256 provides cryptographically secure checksums
+- No cache poisoning vulnerabilities identified
+- Proper input validation on all methods
+
+**Performance**:
+- O(1) cache operations due to OrderedDict
+- Efficient LRU eviction without scanning
+- Minimal memory footprint per entry
+
+### 2. Feed Statistics
+
+**Assessment: EXCELLENT**
+
+The statistics implementation seamlessly integrates with existing monitoring infrastructure:
+
+**Architecture**:
+- `get_feed_statistics()` aggregates from both MetricsBuffer and FeedCache
+- Clean separation between collection (monitoring) and presentation (dashboard)
+- No background jobs or additional processes required
+- Statistics calculated on-demand, preventing stale data
+
+**Data Flow**:
+1. Feed operations tracked via existing `track_feed_generated()`
+2. Metrics stored in MetricsBuffer (existing infrastructure)
+3. Dashboard requests trigger aggregation via `get_feed_statistics()`
+4. Results merged with FeedCache internal statistics
+5. Presented via existing Chart.js + htmx pattern
+
+**Integration Quality**:
+- Reuses existing MetricsBuffer without modification
+- Extends dashboard naturally without new paradigms
+- Defensive programming with fallback values throughout
+
+### 3. OPML 2.0 Export
+
+**Assessment: PERFECT**
+
+The OPML implementation in `/home/phil/Projects/starpunk/starpunk/feeds/opml.py` is a model of simplicity:
+
+**Standards Compliance**:
+- OPML 2.0 specification fully met
+- RFC 822 date format for `dateCreated`
+- Proper XML escaping via `xml.sax.saxutils.escape`
+- All outline elements use `type="rss"` (standard convention)
+- Valid XML structure confirmed by tests
+
+**Design Excellence**:
+- 79 lines including comprehensive documentation
+- Single function, single responsibility
+- No external dependencies beyond stdlib
+- Public access per CQ8 requirement
+- Discovery link correctly placed in base template
+
+## Integration Review
+
+The three components work together harmoniously:
+
+1. **Cache → Statistics**: Cache provides internal metrics that enhance dashboard
+2. **Cache → Feeds**: All feed formats benefit from caching equally
+3. **OPML → Feeds**: Lists all three formats with correct URLs
+4. **Statistics → Dashboard**: Natural extension of existing metrics system
+
+No integration issues identified. Components are loosely coupled with clear interfaces.
+
+## Performance Analysis
+
+### Caching Effectiveness
+
+**Memory Usage**:
+- Maximum 50 cached feeds (configurable)
+- Each entry: ~5-10KB (typical feed size)
+- Total maximum: ~250-500KB memory
+- LRU ensures popular feeds stay cached
+
+**Bandwidth Savings**:
+- 304 responses for unchanged content
+- 5-minute TTL balances freshness vs. performance
+- ETag validation prevents unnecessary regeneration
+
+**Generation Overhead**:
+- SHA-256 checksum: <1ms per operation
+- Cache lookup: O(1) operation
+- Negligible impact on request latency
+
+### Statistics Overhead
+
+- On-demand calculation: ~5-10ms per dashboard refresh
+- No background processing burden
+- Auto-refresh via htmx at 10-second intervals is reasonable
+
+## Security Review
+
+**No Security Concerns Identified**
+
+- SHA-256 checksums are cryptographically secure
+- No user input in cache keys prevents injection
+- OPML properly escapes XML content
+- Statistics are read-only aggregations
+- Dashboard requires authentication
+- OPML public access is by design (CQ8)
+
+## Test Coverage Assessment
+
+**766 Total Tests - EXCEPTIONAL**
+
+### Phase 3 Specific Coverage:
+- **Cache**: 25 tests covering all operations, TTL, LRU, statistics
+- **Statistics**: 11 tests for aggregation and dashboard integration
+- **OPML**: 15 tests for generation, formatting, and routing
+- **Integration**: Tests confirm end-to-end functionality
+
+### Coverage Quality:
+- Edge cases well tested (empty cache, TTL expiration, LRU eviction)
+- Both unit and integration tests present
+- Error conditions properly validated
+- 100% pass rate demonstrates stability
+
+The test suite is comprehensive and provides high confidence in production readiness.
+
+## Production Readiness
+
+**FULLY PRODUCTION READY**
+
+### Deployment Checklist:
+- ✅ All features implemented per specification
+- ✅ 766 tests passing (100% pass rate)
+- ✅ Performance validated (minimal overhead)

+- ✅ Configuration via environment variables ready
+
+### Operational Considerations:
+- Monitor cache hit rates via dashboard
+- Adjust TTL based on traffic patterns
+- Consider increasing max_size for high-traffic sites
+- OPML endpoint may be crawled frequently by feed readers
+
+## Philosophical Alignment
+
+The implementation perfectly embodies StarPunk's core philosophy:
+
+**"Every line of code must justify its existence"**
+
+- Feed cache: 298 lines providing significant performance benefit
+- OPML generator: 79 lines enabling ecosystem integration
+- Statistics: ~100 lines of incremental code leveraging existing infrastructure
+- No unnecessary abstractions or over-engineering
+- Clear, readable code with comprehensive documentation
+
+## Commendations
+
+The developer deserves special recognition for:
+
+1. **Incremental Integration**: Building on existing infrastructure rather than creating new systems
+2. **Standards Mastery**: Perfect OPML 2.0 and HTTP caching implementation
+3. **Test Discipline**: Comprehensive test coverage with meaningful scenarios
+4. **Documentation Quality**: Clear, detailed implementation report and inline documentation
+5. **Performance Consideration**: Efficient algorithms and minimal overhead throughout
+

+# Architect Review: v1.1.2-rc.1 Production Issues
+
+**Date:** 2025-11-28
+**Reviewer:** StarPunk Architect
+**Status:** Design Decisions Provided
+
+## Executive Summary
+
+The developer's investigation is accurate and thorough. Both root causes are correctly identified:
+1. **Static files issue**: HTTP middleware doesn't handle streaming responses properly
+2. **Database metrics issue**: Configuration key mismatch (`METRICS_SAMPLING_RATE` vs `METRICS_SAMPLING_RATES`)
+
+Both issues require immediate fixes. This review provides clear design decisions and implementation guidance.
+
+## Issue 1: Static Files (CRITICAL)
+
+### Root Cause Validation
+✅ **Analysis Correct**: The developer correctly identified that Flask's `send_from_directory()` returns streaming responses in "direct passthrough mode", and accessing `.data` on these triggers a `RuntimeError`.
+
+### Design Decision
+
+**Decision: Skip size tracking for streaming responses**
+
+The HTTP middleware should:
+1. Check if response is in direct passthrough mode BEFORE accessing `.data`
+2. Use `content_length` when available for streaming responses
+3. Record size as 0 when size cannot be determined (not "unknown" - keep metrics numeric)
+
+**Rationale:**
+- Streaming responses are designed to avoid loading entire content into memory
+- The `content_length` header (when present) provides sufficient size information
+- Recording 0 is better than excluding the metric entirely (preserves request count)
+- This aligns with the "minimal overhead" principle in ADR-053
+
+### Implementation Guidance
+
+```python
+# File: starpunk/monitoring/http.py, lines 74-78
+# REPLACE the current implementation with:
+
+# Get response size (handle streaming responses)
+response_size = 0
+if hasattr(response, 'direct_passthrough') and response.direct_passthrough:
+    # Streaming response - don't access .data
+    if hasattr(response, 'content_length') and response.content_length:
+        response_size = response.content_length
+    # else: size remains 0 for unknown streaming responses
+elif response.data:
+    response_size = len(response.data)
+elif hasattr(response, 'content_length') and response.content_length:
+    response_size = response.content_length
+```
+
+**Key Points:**
+- Check `direct_passthrough` FIRST to avoid the error
+- Fall back gracefully when size is unknown
+- Preserve the metric recording (don't skip static files entirely)
+
+## Issue 2: Database Metrics (HIGH)
+
+### Root Cause Validation
+✅ **Analysis Correct**: Configuration key mismatch causes the system to always use 10% sampling, which is insufficient for low-traffic sites.
+
+### Design Decisions
+
+#### Decision 1: Use Singular Configuration Key
+
+**Decision: Use `METRICS_SAMPLING_RATE` (singular) with a single float value**
+
+**Rationale:**
+- Simpler configuration model aligns with our "minimal code" principle
+- Single rate is sufficient for v1.x (no evidence of need for per-type rates)
+- Matches user expectation (config already uses singular form)
+- Can extend to per-type rates in v2.x if needed
+
+#### Decision 2: Default Sampling Rate
+
+**Decision: Default to 100% sampling (1.0)**
+
+**Rationale:**
+- StarPunk is designed for single-user, low-traffic deployments
+- 100% sampling has negligible overhead for typical usage
+- Ensures metrics are always visible (better UX)
+- Power users can reduce sampling if needed via environment variable
+- This matches the intent in config.py (which defaults to 1.0)
+
+#### Decision 3: No Minimum Recording Guarantee
+
+**Decision: Keep simple percentage-based sampling without guarantees**
+
+**Rationale:**
+- Additional complexity not justified for v1.x
+- 100% default sampling eliminates the zero-metrics problem
+- Minimum guarantees would complicate the clean sampling logic
+- YAGNI principle - we can add this if users report issues
+
+### Implementation Guidance
+
+**Step 1: Fix MetricsBuffer to accept float sampling rate**
+
+```python
+# File: starpunk/monitoring/metrics.py, lines 95-110
+# Modify __init__ to accept either dict or float:
+
+def __init__(self, max_size: int = 1000, sampling_rates: Optional[Union[Dict[str, float], float]] = None):
+    """Initialize metrics buffer.
+
+    Args:
+        max_size: Maximum number of metrics to store
+        sampling_rates: Either a float (0.0-1.0) for all operations,
+                       or dict mapping operation type to rate
+    """
+    self.max_size = max_size
+    self._buffer: Deque[Metric] = deque(maxlen=max_size)
+    self._lock = Lock()
+    self._process_id = os.getpid()
+
+    # Handle both float and dict formats
+    if sampling_rates is None:
+        # Default to 100% sampling for low-traffic sites
+        self._sampling_rates = {"database": 1.0, "http": 1.0, "render": 1.0}
+    elif isinstance(sampling_rates, (int, float)):
+        # Single rate for all operation types
+        rate = float(sampling_rates)
+        self._sampling_rates = {"database": rate, "http": rate, "render": rate}
+    else:
+        # Dict of per-type rates
+        self._sampling_rates = sampling_rates
+```
+
+**Step 2: Fix configuration reading**
+
+```python
+# File: starpunk/monitoring/metrics.py, lines 336-341
+# Change to read the singular key:
+
+try:
+    from flask import current_app
+    max_size = current_app.config.get('METRICS_BUFFER_SIZE', 1000)
+    sampling_rate = current_app.config.get('METRICS_SAMPLING_RATE', 1.0)  # Singular, defaults to 1.0
+except (ImportError, RuntimeError):
+    # Flask not available or no app context
+    max_size = 1000
+    sampling_rate = 1.0  # Default to 100% for low-traffic sites
+
+_metrics_buffer = MetricsBuffer(
+    max_size=max_size,
+    sampling_rates=sampling_rate  # Pass the float directly
+)
+```
+
+## Priority and Release Strategy
+
+### Fix Priority
+1. **First**: Issue 1 (Static Files) - Site is unusable without this
+2. **Second**: Issue 2 (Database Metrics) - Feature incomplete but not blocking
+
+### Release Approach
+
+**Decision: Create v1.1.2-rc.2 (not a hotfix)**
+
+**Rationale:**
+- These are bugs in a release candidate, not a stable release
+- Following our git branching strategy, continue on the feature branch
+- Test thoroughly before promoting to stable v1.1.2
+
+### Implementation Steps
+
+1. Fix static file handling (Issue 1)
+2. Fix metrics configuration (Issue 2)
+3. Add integration tests for both issues
+4. Deploy v1.1.2-rc.2 to production
+5. Monitor for 24 hours
+6. If stable, tag as v1.1.2 (stable)
+
+## Testing Requirements
+
+### For Issue 1 (Static Files)
+- Test that all static files load correctly (CSS, JS, images)
+- Verify metrics still record for static files (with size when available)
+- Test with both small and large static files
+- Verify no errors in logs
+
+### For Issue 2 (Database Metrics)
+- Verify database metrics appear immediately (not zero)
+- Test with `METRICS_SAMPLING_RATE=0.1` environment variable
+- Verify backwards compatibility (existing configs still work)
+- Check that slow queries (>1s) are always recorded regardless of sampling
+
+### Integration Test Additions
+
+```python
+# tests/test_monitoring_integration.py
+
+def test_static_file_metrics_recording():
+    """Static files should not cause 500 errors and should record metrics."""
+    response = client.get('/static/css/style.css')
+    assert response.status_code == 200
+    # Verify metric was recorded (even if size is 0)
+
+def test_database_metrics_with_sampling():
+    """Database metrics should respect sampling configuration."""
+    app.config['METRICS_SAMPLING_RATE'] = 0.5
+    # Perform operations and verify ~50% are recorded
+```
+
+## Configuration Documentation Update
+
+Update the deployment documentation to clarify:
+
+```markdown
+# Environment Variables
+
+## Metrics Configuration
+- `METRICS_ENABLED`: Enable/disable metrics (default: true)
+- `METRICS_SAMPLING_RATE`: Percentage of operations to record, 0.0-1.0 (default: 1.0)
+  - 1.0 = 100% (recommended for low-traffic sites)
+  - 0.1 = 10% (for high-traffic deployments)
+- `METRICS_BUFFER_SIZE`: Number of metrics to retain (default: 1000)
+- `METRICS_SLOW_QUERY_THRESHOLD`: Slow query threshold in seconds (default: 1.0)
+```
+
+## Summary
+
+The developer's investigation is excellent. The fixes are straightforward:
+
+1. **Static files**: Add a simple check for `direct_passthrough` before accessing `.data`
+2. **Database metrics**: Standardize on singular config key with 100% default sampling
+
+Both fixes maintain our principles of simplicity and minimalism. No new dependencies, no complex logic, just fixing the bugs while keeping the code clean.
+
+The developer should implement these fixes in order of priority, thoroughly test, and deploy as v1.1.2-rc.2.

+The v1.2.0 feature specification has been updated with all user decisions and architectural designs. The three core features (Custom Slugs, Media Upload, Microformats2) are fully specified with implementation details, database schemas, and edge case handling.
+
+## User Decisions Incorporated
+
+### 1. Custom Slugs
+- **Decision**: Read-only after creation (Option B)
+- **Implementation**: Field disabled on edit form with warning message
+- **Rationale**: Prevents broken permalinks
+
+### 2. Media Upload
+- **Storage**: `data/media/` directory (Option A)
+- **URL Structure**: Date-organized `/media/2025/01/filename.jpg` (Option A)
+- **Insertion**: Auto-insert markdown at cursor position (Option A)
+- **Tracking**: Database table for metadata (Option A)
+- **Format**: Minimal markdown `![](url)` for simplicity
+
+### 3. Microformats2 / Author Discovery
+- **Critical Decision**: Author info discovered from IndieAuth profile URL
+- **NOT** environment variables or config files
+- **Implementation**: New discovery system with caching
+- **h-card Placement**: Only within h-entries (Option B)
+- **Fallback**: Graceful degradation when discovery fails
+
+## Architectural Decisions
+
+### ADR-061: Author Profile Discovery
+Created new Architecture Decision Record documenting:
+- Discovery from IndieAuth profile URL
+- Database caching strategy
+- Fallback behavior
+- Integration with existing auth flow
+
+### Database Changes
+Two new tables required:
+1. `media` - Track uploaded files with metadata
+2. `author_profile` - Cache discovered author information
+
+### Security Considerations
+- Media validation (MIME types, file size)
+- Slug validation (URL-safe characters)
+- Directory traversal prevention
+- No SVG uploads (XSS risk)
+
+## Implementation Guidance
+
+### Phase 1: Custom Slugs (Simplest)
+- Template changes only
+- Validation in existing create/edit routes
+- No database changes needed
+
+### Phase 2: Microformats2 + Author Discovery
+- Build discovery module first
+- Integrate with auth flow
+- Update templates with discovered data
+- Add manual refresh in admin
+
+### Phase 3: Media Upload (Most Complex)
+- Create media module
+- Database migration for media table
+- AJAX upload endpoint
+- Cursor tracking JavaScript
+
+## Standards Compliance Verified
+
+### Microformats2
+- h-entry: All properties optional (confirmed via spec)
+- h-feed: Proper container structure
+- h-card: Standard properties for author
+- rel-me: Identity verification links
+
+### IndieWeb
+- IndieAuth profile discovery pattern
+- Micropub compatibility maintained
+- RSS/Atom feed preservation
+
+## Edge Cases Addressed
+
+### Author Discovery
+- Multiple h-cards on profile
+- Missing properties
+- Network failures
+- Invalid markup
+- All have graceful fallbacks
+
+### Media Upload
+- Concurrent uploads
+- Orphaned files
+- Invalid MIME types
+- File size limits
+
+### Custom Slugs
+- Uniqueness validation
+- Character restrictions
+- Immutability enforcement
+
+## No Outstanding Questions
+
+All user requirements have been addressed. The design is complete and ready for developer implementation.
+
+## Success Criteria Defined
+
+Eight clear metrics for v1.2.0 success:
+1. Custom slug specification (immutable)

+# v1.2.0 Phase 1: Custom Slugs - Architectural Review
+
+**Date**: 2025-11-28
+**Architect**: StarPunk Architect Subagent
+**Component**: Custom Slug Implementation (Phase 1 of v1.2.0)
+**Status**: APPROVED WITH MINOR NOTES
+
+## Executive Summary
+
+The Phase 1 implementation of custom slugs for v1.2.0 has been successfully completed. The implementation demonstrates excellent code quality, comprehensive test coverage, and strict adherence to the design specifications. The feature is production-ready and can proceed to Phase 2.
+
+## What Went Well
+
+### Architecture & Design
+- **Excellent reuse of existing infrastructure** - Leverages `slug_utils.py` without modification
+- **Clean separation of concerns** - Validation logic properly abstracted
+- **Minimal code footprint** - Only necessary files modified (templates and route handler)
+- **No database schema changes** - Works with existing slug column
+- **Proper error handling** - Graceful fallbacks for all edge cases
+
+### Implementation Quality
+- **Form design matches specification exactly** - Optional field with clear guidance
+- **Read-only edit behavior** - Prevents permalink breakage as specified
+- **Consistent validation** - Uses same rules as Micropub for uniformity
+- **Auto-sanitization approach** - User-friendly experience over strict rejection
+- **Clear user messaging** - Helpful placeholder text and validation hints
+
+### Test Coverage Assessment
+- **30 comprehensive tests** - Excellent coverage of all scenarios
+- **Edge cases well handled** - Unicode, emoji, whitespace, hierarchical paths
+- **Validation thoroughly tested** - All sanitization rules verified
+- **Web UI integration tests** - Forms and submission flows covered
+- **Micropub consistency verified** - Ensures uniform behavior across entry points
+- **All tests passing** - Clean test suite execution
+
+## Design Adherence
+
+### Specification Compliance
+The implementation perfectly matches the v1.2.0 feature specification:
+- Custom slug field in creation form with optional input
+- Read-only display in edit form with explanation
+- Validation pattern `[a-z0-9-]+` enforced
+- Auto-sanitization of invalid input
+- Fallback to auto-generation when empty
+- Reserved slug handling with suffix addition
+- Hierarchical path rejection
+
+### Developer Q&A Alignment
+All developer Q&A answers were followed precisely:
+- **Q1**: New slugs validated, existing slugs unchanged
+- **Q2**: Edit form uses readonly (not disabled) with visible value
+- **Q3**: Server-side validation with auto-sanitization
+- **Q7**: Slugs cannot be changed after creation
+- **Q39**: Same validation as Micropub for consistency
+
+### ADR Compliance
+Aligns with ADR-035 (Custom Slugs in Micropub):
+- Accepts custom slug parameter
+- Validates and sanitizes input
+- Ensures uniqueness with suffix strategy
+- Falls back to auto-generation
+- Handles reserved slugs gracefully
+
+## Code Quality
+
+### Strengths
+- **Clean, readable code** - Well-structured and documented
+- **Follows project patterns** - Consistent with existing codebase style
+- **Proper error handling** - Try/catch blocks with specific error types
+- **Good separation** - UI, validation, and persistence properly separated
+- **Comprehensive docstrings** - Test file well-documented with Q&A references
+
+### Minor Observations
+1. **Version number not updated** - Still shows v1.1.2 in `__init__.py` (should be v1.2.0-dev or similar)
+2. **CHANGELOG entry in Unreleased** - Correct placement for work in progress
+3. **Test comment accuracy** - One test has a minor comment issue about regex behavior (line 84)
+
+## Security Analysis
+
+### Properly Handled
+- **Path traversal protection** - Hierarchical paths rejected
+- **Reserved slug protection** - System routes protected with suffix
+- **Input sanitization** - All user input properly sanitized
+- **No SQL injection risk** - Using parameterized queries
+- **Length limits enforced** - 200 character maximum respected
+
+### No Issues Found
+The implementation has no security vulnerabilities or concerns.
+
+## Performance Considerations
+
+### Efficient Implementation
+- **Minimal database queries** - Single query for existing slugs
+- **No performance regression** - Reuses existing validation functions
+- **Fast sanitization** - Regex-based operations are efficient
+- **No additional I/O** - Works within existing note creation flow
+
+## User Experience
+
+### Excellent UX Decisions
+- **Clear field labeling** - "Custom Slug (optional)" is unambiguous
+- **Helpful placeholder** - "leave-blank-for-auto-generation" guides users
+- **Inline help text** - Explains allowed characters clearly
+- **Graceful error handling** - Sanitizes rather than rejects
+- **Preserved form data** - On error, user input is maintained
+- **Success feedback** - Flash message shows final slug used
+
+## Minor Suggestions for Improvement
+
+These are optional enhancements that could be considered later:
+
+1. **Client-side validation preview** - Show sanitized slug as user types (future enhancement)
+2. **Version number update** - Update `__version__` to reflect v1.2.0 development
+3. **Test comment correction** - Fix comment on line 84 about consecutive hyphens
+4. **Consider slug preview** - Show what the auto-generated slug would be (UX enhancement)
+
+## Risk Assessment

+- UUID-based filename generation prevents collisions effectively
+- Date-organized storage structure (`data/media/YYYY/MM/`) implemented correctly
+- Proper EXIF orientation handling
+- Security measures well-implemented (path traversal prevention, MIME validation)
+
+### 3. **Database Design**
+- Junction table approach provides excellent flexibility
+- Foreign key constraints and cascade deletes properly configured
+- Indexes appropriately placed for query performance
+- Caption support integrated seamlessly
+
+### 4. **Feed Integration**
+- RSS: HTML embedding in CDATA blocks works perfectly

+- JSON Feed: Native attachments array cleanly implemented
+- Absolute URLs correctly generated across all feed formats
+
+### 5. **Error Handling**
+- Graceful handling of invalid images
+- Clear error messages for users
+- Non-atomic upload behavior (per Q35) allows partial success
+
+### 6. **Test Coverage**
+- Comprehensive test suite using PIL-generated images (no binary files)
+- All edge cases covered: file size, dimensions, format validation
+- Multiple image attachment scenarios tested
+- Caption handling verified
+
+### 7. **Performance Optimizations**
+- Immutable cache headers (1 year) for served media
+- Efficient image resizing strategy (2048px threshold)
+- Lazy loading potential with width/height stored
+
+## ⚠️ Issues Found
+
+### Minor Issues (Non-blocking)
+
+1. **GIF Animation Handling**
+   - Line 119 in `media.py`: Animated GIFs are returned unoptimized
+   - This is acceptable for v1.2.0 but should be documented as a known limitation
+   - Recommendation: Add comment explaining why animated GIFs skip optimization
+
+2. **Missing Input Validation in Route**
+   - `admin.py` lines 114-128: No check for empty file uploads before processing
+   - While handled by `save_media()`, earlier validation would be cleaner
+   - Recommendation: Skip empty filename entries before calling save_media
+
+3. **Preview JavaScript Accessibility**
+   - `new.html` lines 139-140: Preview images lack proper alt text
+   - Should use filename or "Preview" + index for better accessibility
+   - Recommendation: Update JavaScript to include meaningful alt text
+
+### Observations (No Action Required)
+
+1. **No Thumbnail Generation**: As per design, relying on CSS for responsive sizing
