From 093cd1930a30b7fc551dc3d52e65796757acd78f Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 28 Oct 2025 09:17:55 +0000 Subject: [PATCH 1/5] feat: implement Garden Sync - local-first P2P sync with Yjs and WebRTC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add "garden pattern" synchronization where a primary device (desktop) acts as a "garden" hub and portals (laptop/phone) sync via WebRTC P2P when on same network. Key Features: - Yjs CRDT-based sync for conflict-free replication - WebRTC P2P connection with BroadcastChannel fallback - Legend State <-> Yjs bidirectional sync adapter - Zero-server architecture (uses public signaling servers) - Optional encryption with shared password - Real-time connection status and peer count indicators Architecture: - YjsGardenSync adapter bridges Legend State observables with Yjs shared types - Automatic lifecycle management based on settings - All 7 entity collections synced: moments, areas, habits, cycles, phase configs, crystallized routines, and metric logs UI Integration: - Garden Sync settings section in SettingsDrawer - Enable/disable toggle with device role selector (Garden/Portal) - Room name generator and input (6-char code: ABC123) - Optional password for encrypted sync - Connection status indicator with peer count - Debug mode toggle for development Commands: - :garden - Open garden sync settings via Vim command mode - Cmd+K -> "Garden Sync Settings" in command palette Technical Details: - Dependencies: yjs@13.6.27, y-webrtc@10.3.0, y-protocols@1.0.6 - Sync managed in StoreInitializer with useEffect lifecycle - Settings persisted to localStorage via Legend State - Status and peer count exposed as observables for UI reactivity 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- package.json |
