• Add full multi-table schema for collections with normalized design (collections, collection_templates, collection_items, collection_item_versions)
• Implement collection detection and processing in enhancement pipeline for .insertr-add elements
• Add template extraction and storage from existing HTML children with multi-variant support
• Enable collection reconstruction from database on server restart with proper DOM rebuilding
• Extend ContentClient interface with collection operations and full database integration
• Update enhance command to use engine.DatabaseClient for collection persistence support
Major architectural simplification removing content type complexity:
Database Schema:
- Remove 'type' field from content and content_versions tables
- Simplify to pure HTML storage with html_content + original_template
- Regenerate all sqlc models for SQLite and PostgreSQL
API Simplification:
- Remove content type routing and validation
- Eliminate type-specific handlers (text/markdown/structured)
- Unified HTML-first approach for all content operations
- Simplify CreateContent and UpdateContent to HTML-only
Backend Enhancements:
- Update enhancer to only generate data-content-id (no data-content-type)
- Improve container expansion utilities with comprehensive block/inline rules
- Add Phase 3 preparation with boundary-respecting traversal logic
- Strengthen element classification for viable children detection
Documentation:
- Update TODO.md to reflect Phase 1-3 completion status
- Add WORKING_ON.md documenting the architectural transformation
- Mark container expansion and HTML-first architecture as complete
This completes the transition to a unified HTML-first content management system
with automatic style detection and element-based behavior, eliminating the
complex multi-type system in favor of semantic HTML-driven editing.
- Add backend container transformation in engine.go following syntactic sugar specification
- Containers with .insertr get class removed and viable children get .insertr added
- Remove incorrect frontend container expansion - frontend only finds enhanced elements
- Fix StyleAwareEditor hasMultiPropertyElements runtime error
- Add addClass/removeClass methods to ContentEngine for class manipulation
- Update frontend to match HTML-first approach with no runtime container logic
- Test verified: container <section class='insertr'> transforms to individual h1.insertr, p.insertr, button.insertr
This completes the container expansion functionality per CLASSES.md:
Developer convenience (one .insertr enables section editing) + granular control (individual element editing)
- Add sibling context detection to identify unique heading content
- Include parent container context with enhanced class filtering
- Look for heading siblings (h1-h6) that provide unique container context
- Extract up to 12 chars of sibling heading text for differentiation
Results:
✅ Collision Elimination: From 8 collisions to 0 collisions
✅ Unique Base IDs: Each element gets distinct ID (no -1, -2, -3 suffixes)
✅ Better Context: 'Example 1', 'Example 2' headings provide unique signatures
✅ Maintained Stability: Same elements still get same IDs across runs
Before: index-p-cad2a8, index-p-cad2a8-1, index-p-cad2a8-2... (8 collisions)
After: index-p-1198e8, index-p-215de9, index-p-604e11... (0 collisions)
- Remove content preview from ID generation for stable structural IDs
- Implement database-first approach to check content existence before creation
- Add enhanced DOM path, semantic context, and precise sibling indexing
- Replace HTML attribute checking with reliable database lookups
- Add collision handling with increment counters for similar elements
Fixes:
✅ UNIQUE constraint errors eliminated (multiple enhancement runs work)
✅ Structural stability (same element keeps same ID regardless of content changes)
✅ Database-driven workflow (single source of truth for content existence)
✅ Enhanced collision resistance with detailed structural differentiation
Results: No more 'Failed to store content' errors, stable enhance workflow.
- Replace random UUID with 6-component deterministic signature
- Use filePath|domPath|tag|classes|contentPreview|siblingIndex for uniqueness
- Enhance sibling positioning with insertr-aware index calculation
- Improve DOM path generation with meaningful class inclusion
- Restore ID consistency across enhancement runs for reliable content injection
Results:
✅ ID Consistency: Same elements always get same IDs (index-p-639460)
✅ Collision Resistance: Different elements get different IDs (4c7206, 23df20, 5a975d)
✅ File Scoping: Same structure in different files gets different IDs
✅ Enhanced Workflow: API edit → enhance button → content injected successfully
Fixes enhance button by ensuring API content IDs match enhancement-generated IDs.
- Replace random UUID suffix with deterministic hash-based signature
- Use element DOM path, sibling position, and content preview for uniqueness
- Ensure same elements always get the same content ID across enhancements
- Fix critical bug where content updates weren't being injected into static files
This resolves the enhance button workflow: API content updates → enhance trigger → static file injection.
- Replace value field with html_content for direct HTML storage
- Add original_template field for style detection preservation
- Remove all markdown processing from injector (delete markdown.go)
- Fix critical content extraction/injection bugs in engine
- Add missing UpdateContent PUT handler for content persistence
- Fix API client field names and add updateContent() method
- Resolve content type validation (only allow text/link types)
- Add UUID-based ID generation to prevent collisions
- Complete first-pass processing workflow for unprocessed elements
- Verify end-to-end: Enhancement → Database → API → Editor → Persistence
All 37 files updated for HTML-first content management system.
Phase 3a implementation complete and production ready.
- Remove complex style preservation system from editor
- Simplify markdown conversion back to straightforward approach
- Remove StyleContext class and style-aware conversion methods
- Switch content type from 'html' back to 'markdown' for consistency
- Clean up editor workflow to focus on core markdown editing
- Remove ~500 lines of unnecessary style complexity
This completes the UI unification cleanup by removing the overly complex
style preservation system that was making the editor harder to maintain.
- Add StyleContext class for extracting and applying HTML attributes/styles
- Enhance MarkdownConverter with style-aware conversion methods
- Switch backend storage from markdown to HTML with 'html' content type
- Update editor workflow to preserve CSS classes, IDs, and attributes

- Remove obsolete cmd/auto_enhance.go command (replaced by unified enhance)
- Implement EnhanceInPlace method using unified pipeline
- Remove generated demo files from git tracking
- Verify all functionality works after cleanup:
* go build successful
* enhance command working correctly
* unified pipeline (discovery → ID generation → content injection) verified
* clean command structure (only enhance, serve, restore commands)
The codebase is now clean with no legacy auto-enhance references or stub implementations. All functionality consolidated into the unified Discoverer + Enhancer architecture.
- Move all ContentItem, ContentClient, ContentResponse types to engine/types.go as single source of truth
