Phase 12C: Core Blocks and Gutenberg Parity - Complete

[pipewrk]

Summary

Phase 12C - Core Blocks and Gutenberg Parity is now COMPLETE! 🎉

✅ All Tasks Completed: 74/74 (100%)

This phase delivered full WordPress Gutenberg block parity with deterministic releases, enabling seamless migration from WordPress to EdgePress.

Key Achievements

1. Editor DevTools (Slice 0)

• ✅ BlockTreeInspector for visualizing canonical block trees
• ✅ DiagnosticsInspector for transform/renderer diagnostics
• ✅ ThemeTokenInspector for token inspection
• ✅ TransformTracer for operation tracing
• ✅ DevToolsPanel for unified devtools interface
• ✅ useDevToolsState hook for state management

2. Block Hardening (Slice 1)

• ✅ Canonical block schema invariants validation
• ✅ Block lossiness categorization (none/partial/unsupported)
• ✅ Fallback mechanism for partial transforms
• ✅ Sanitize utility for XSS protection
• ✅ Embed policy for iframe restrictions

3. Featured Image/Media Parity (Slice 2)

• ✅ MediaPicker component replaces raw ID input
• ✅ Integration with document settings panel
• ✅ Thumbnail preview for selected images
• ✅ Clear/remove button for featured images
• ✅ Admin shell acceptance tests
• ✅ API flow acceptance tests

4. Navigation Block Parity (Slice 3)

• ✅ coreNavigation.js mapping: import transform + renderer
• ✅ Menu resolution in preview context (frozen revision set)
• ✅ Menu snapshotting in release workflow (deterministic releases)
• ✅ sourceRevisionSet menu schema with versioning
• ✅ Golden tests for import/render transforms
• ✅ Acceptance test for end-to-end navigation flow
• ✅ Deterministic releases: menu changes trigger new releaseId

5. Templates/Patterns Lifecycle (Slice 4)

• ✅ Pattern/template types added to VALID_DOCUMENT_TYPES
• ✅ Patterns CRUD controller with full endpoints
• ✅ Patterns domain logic in patterns.js
• ✅ WP facade wired to real pattern queries
• ✅ Pattern/test suite with CRUD and facade tests
• ✅ WP compatibility profile documented

6. Theme Parity Completion (Slice 5)

• ✅ renderShell.js: unified HTML wrapper factory
• ✅ tokenExport.js: theme token → CSS variable converter
• ✅ Preview uses renderShell with theme vars
• ✅ Publish uses renderShell with site tokens
• ✅ Editor canvas injected with site tokens (isolated from admin)
• ✅ Theme shell parity contract test suite

7. Parity Gap Closeout (Slice 6)

• ✅ parity-audit.js CLI tool for diagnostics
• ✅ Block traversal to identify navigation blocks
• ✅ Transform coverage analysis
• ✅ Missing mapping detection
• ✅ Partial/fallback lossiness documentation
• ✅ Actionable recommendations
• ✅ WP compatibility profile updated with audit findings

Architecture Decisions

1. Document-Backed Registry: Patterns and templates are `Document.type = '''pattern'` or `'template'`, not separate entities. This enables full revision history and deterministic releases.

2. Deterministic Releases: sourceRevisionSet now includes menu snapshots. Every render-time resolution uses frozen state. Menu changes trigger new `releaseId`.

3. Theme Token Isolation: Implemented CSS variable prefixes (`--ep-admin-` for UI, `--ep-site-` for content) to prevent theme leakage between admin and site rendering.
