Radicle Network Integration

[ProjectLiminality]

Description

Parent Specification: #270 - Radicle Integration Specification
Parent Epic: #258 - Coherence Beacon System

Implement complete Radicle CLI integration to enable peer-to-peer DreamNode collaboration on macOS/Linux. This establishes the primary network layer for InterBrain's decentralized collective cognition system.

Enhanced Acceptance Criteria

Radicle Integration

• DreamNode creation automatically runs rad init after git init SUPERSEDED: Implemented superior lazy initialization pattern
• Graceful handling if Radicle unavailable (creation continues)
• "Share DreamNode" command checks for new commits to share
• Share command disabled/returns message if nothing new
• rad push executes in background with status indicator
• Success notification after successful share
• Clone command accepts Radicle ID input
• Clone auto-derives DreamNode name from Radicle metadata
• Clone command runs rad clone and integrates into vault

Metadata & Contact Info

• radicleId field added to DreamNode metadata structure
• Radicle ID saved alongside email/phone contact fields
• Metadata persists correctly in .udd file (single JSON file)

Platform Compatibility

• Platform detection prevents Radicle on Windows
• Placeholder code structure for future GitHub implementation
• Windows limitation documented in README

Error Handling

• Radicle errors logged and reported to user
• Core DreamNode operations continue despite Radicle failures
• Clear error messages for missing Radicle installation

Documentation

• Platform compatibility notes (macOS/Linux only)
• Windows limitation and future GitHub solution noted
• Radicle CLI installation guide in README (deferred - can be added incrementally)
• Radicle identity setup instructions (rad auth) (deferred - can be added incrementally)

Implementation Summary

✅ Core Features Implemented

1. Lazy Radicle Initialization (Superior to Original Plan)

• DreamNodes created local-first (no automatic init on creation)
• Intelligent initialization triggered on first network use (video call email export)
• RadicleBatchInitService handles batch rad init with race condition prevention
• Graceful degradation if Radicle unavailable

2. Clone Workflow with Deep Links

• Obsidian URI protocol: obsidian://interbrain-clone?id=rad:...
• Auto-derive DreamNode name from Radicle metadata
• Duplicate detection with performance optimization
• Auto-refresh after clone (vault scan + relationship scan + constellation layout)
• Auto-focus on cloned/existing nodes
• Batch clone support for multiple nodes

3. Share Command

• Manual "Share DreamNode" command
• Background rad push operation
• Status notifications
• Error handling and graceful degradation

4. Performance Optimizations

• Constellation repositioning: 100x faster (10s → 100ms)
• Radicle duplicate detection: ~10x faster (parallel I/O + early exit)
• Parallel DreamSong relationship scanning

5. Metadata & Storage

• radicleId field in UDD schema and runtime types
• Auto-save Radicle ID to .udd file after clone
• Contact field integration (email, phone, radicleId)

User Testing Results

✅ User testing completed successfully
✅ Clone workflow validated with real Radicle network
✅ Duplicate detection works instantly
✅ Auto-focus and auto-refresh working perfectly
✅ Performance optimizations confirmed (~100ms repositioning)
✅ No outstanding issues identified

Technical Achievements

Key Implementation Decisions:

1. Lazy initialization (better than automatic init-on-creation)
2. Single .udd file (not directory structure)
3. Parallel I/O for relationship scanning
4. Batch position updates for instant repositioning
5. Early exit patterns for duplicate detection

Architecture Patterns:

• Dependency injection for service composition
• Graceful error handling throughout
• Platform detection for cross-platform compatibility
• Intelligent caching with .udd file storage

Definition of Done

• Implementation complete and tested on macOS
• Platform detection working correctly
• All enhanced acceptance criteria met (see above)
• User testing validated core functionality
• Performance optimizations implemented
• Comprehensive documentation (deferred to incremental updates)

Next Steps

Feature Complete - Ready for epic integration

Documentation enhancements (can be separate PRs):

• Detailed Radicle setup section in README
• rad auth configuration guide
• Troubleshooting section
