+## Description
 
+<!-- SECTION:DESCRIPTION:BEGIN -->
+IndexedDB persistence is already implemented via @automerge/automerge-repo-storage-indexeddb. The remaining work is:
+
+1. Add real online/offline detection (currently always returns "online")
+2. Create UI indicator showing connection status
+3. Handle Safari's 7-day IndexedDB eviction
+
+Existing code locations:
+- src/automerge/useAutomergeSyncRepo.ts (lines 346, 380-432)
+- src/automerge/useAutomergeStoreV2.ts (connectionStatus property)
+- src/automerge/documentIdMapping.ts (room→document mapping)
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Real WebSocket connection state tracking (not hardcoded 'online')
+- [x] #2 navigator.onLine integration for network detection
+- [x] #3 UI indicator component showing connection status
+- [x] #4 Visual feedback when working offline
+- [x] #5 Auto-reconnect with status updates
+- [ ] #6 Safari 7-day eviction mitigation (service worker or periodic touch)
+<!-- AC:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Implemented connection status tracking:
+- Added ConnectionState type and tracking in CloudflareAdapter
+- Added navigator.onLine integration for network detection
+- Exposed connectionState and isNetworkOnline from useAutomergeSync hook
+- Created ConnectionStatusIndicator component with visual feedback
+- Shows status only when not connected (connecting/reconnecting/disconnected/offline)
+- Auto-hides when connected and online

+Text shapes created with the "T" text tool show up on the creating client but not on other clients viewing the same board.

+- Text shapes ARE being persisted to R2 (confirmed in server logs)

+- Line 1142: 'text' is in invalidTextProps list and gets deleted

+Replace the current "last-write-wins" full document replacement with proper Automerge CRDT sync protocol. This ensures deletions are preserved across offline/reconnect scenarios and concurrent edits merge correctly.
+
+Current problem: Server does `currentDoc.store = { ...newDoc.store }` which is full replacement, not merge. This causes "ghost resurrection" of deleted shapes when offline clients reconnect.
+
+Solution: Use Automerge's native binary sync protocol with proper CRDT merge semantics.
+<!-- SECTION:DESCRIPTION:END -->

+Implement a biologically-inspired signal propagation system for the canvas network, modeling how information, attention, and value flow through the collaborative space like nutrients through mycelium.

+- Nodes: Points of interest, events, people, resources, discoveries
+- Hyphae: Connections/paths between nodes (relationships, routes, attention threads)
+- Signals: Urgency, relevance, trust, novelty gradients
+- Behaviors: Gradient following, path optimization, emergence detection
+
+Features:
+- Signal emission when events/discoveries occur
+- Decay with spatial, relational, and temporal distance
+- Aggregation at nodes (multiple weak signals → strong signal)
+- Spore dispersal pattern for notifications
+- Resonance detection (unconnected focus on same location)

+- Attention: Heatmap of collective focus, nodes sized by current attention
+- Incentive: Value gradients, token flows, MycoFi integration
+- Relational: Social graph topology, force-directed layout
+- Possibility: Branching futures, what-if scenarios, alternate timelines
+
+Features:
+- Smooth transitions between lens types
+- Lens blending (e.g., 50% geographic + 50% attention)
+- Temporal scrubber for historical playback
+- Temporal portals (click location to see across time)
+- Living maps that grow/fade based on attention
+
