+# Data Safety Verification: TldrawDurableObject → AutomergeDurableObject Migration
+
+## Overview
+
+This document verifies that the migration from `TldrawDurableObject` to `AutomergeDurableObject` is safe and will not result in data loss.
+
+## R2 Bucket Configuration ✅
+
+### Production Environment
+- **Bucket Binding**: `TLDRAW_BUCKET`
+- **Bucket Name**: `jeffemmett-canvas`
+- **Storage Path**: `rooms/${roomId}`
+- **Configuration**: `wrangler.toml` lines 30-32
+
+### Development Environment
+- **Bucket Binding**: `TLDRAW_BUCKET`
+- **Bucket Name**: `jeffemmett-canvas-preview`
+- **Storage Path**: `rooms/${roomId}`
+- **Configuration**: `wrangler.toml` lines 72-74
+
+## Data Storage Architecture
+
+### Where Data is Stored
+
+1. **Document Data (R2 Storage)** ✅
+   - **Location**: R2 bucket at path `rooms/${roomId}`
+   - **Format**: JSON document containing the full board state
+   - **Persistence**: Permanent storage, independent of Durable Object instances
+   - **Access**: Both `TldrawDurableObject` and `AutomergeDurableObject` use the same R2 bucket and path
+
+2. **Room ID (Durable Object Storage)** ⚠️
+   - **Location**: Durable Object's internal storage (`ctx.storage`)
+   - **Purpose**: Cached room ID for the Durable Object instance
+   - **Recovery**: Can be re-initialized from URL path (`/connect/:roomId`)
+
+### Data Flow

+
+## Migration Safety Guarantees
+
+### ✅ No Data Loss Risk
+
+1. **R2 Data is Independent**
+   - Document data is stored in R2, not in Durable Object storage
+   - R2 data persists even when Durable Object instances are deleted
+   - Both classes use the same R2 bucket (`TLDRAW_BUCKET`) and path (`rooms/${roomId}`)
+
+2. **Stub Class Ensures Compatibility**
+   - `TldrawDurableObject` extends `AutomergeDurableObject`
+   - Uses the same R2 bucket and storage path
+   - Existing instances can access their data during migration
+
+3. **Room ID Recovery**
+   - `roomId` is passed in the URL path (`/connect/:roomId`)
+   - Can be re-initialized if Durable Object storage is lost
+   - Code handles missing `roomId` by reading from URL (see `AutomergeDurableObject.ts` lines 43-49)
+
+4. **Automatic Format Conversion**
+   - `AutomergeDurableObject` handles multiple data formats:
+     - Automerge Array Format: `[{ state: {...} }, ...]`
+     - Store Format: `{ store: { "recordId": {...}, ... }, schema: {...} }`
+     - Old Documents Format: `{ documents: [{ state: {...} }, ...] }`
+   - Conversion preserves all data, including custom shapes and records
+
+### Migration Process
+
+1. **Deployment with Stub**
+   - `TldrawDurableObject` stub class is exported
+   - Cloudflare recognizes the class exists
+   - Existing instances can continue operating
+
+2. **Delete-Class Migration**
+   - Migration tag `v2` with `deleted_classes = ["TldrawDurableObject"]`
+   - Cloudflare will delete Durable Object instances (not R2 data)
+   - R2 data remains untouched
+
+3. **Data Access After Migration**
+   - New `AutomergeDurableObject` instances can access the same R2 data
+   - Same bucket (`TLDRAW_BUCKET`) and path (`rooms/${roomId}`)
+   - Automatic format conversion ensures compatibility
+
+## Verification Checklist
+
+- [x] R2 bucket binding is correctly configured (`TLDRAW_BUCKET`)
+- [x] Both production and dev environments have R2 buckets configured
+- [x] `AutomergeDurableObject` uses `env.TLDRAW_BUCKET`
+- [x] Storage path is consistent (`rooms/${roomId}`)
+- [x] Stub class extends `AutomergeDurableObject` (same R2 access)
+- [x] Migration includes `delete-class` for `TldrawDurableObject`
+- [x] Code handles missing `roomId` by reading from URL
+- [x] Format conversion logic preserves all data types
+- [x] Custom shapes and records are preserved during conversion
+
+## Testing Recommendations
+
+1. **Before Migration**
+   - Verify R2 bucket contains expected room data
+   - List rooms: `wrangler r2 object list TLDRAW_BUCKET --prefix "rooms/"`
+   - Check a sample room's format
+
+2. **After Migration**
+   - Verify rooms are still accessible
+   - Check that data format is correctly converted
+   - Verify custom shapes and records are preserved
+   - Monitor worker logs for conversion statistics
+
+3. **Data Integrity Checks**
+   - Shape count matches before/after
+   - Custom shapes (ObsNote, Holon, etc.) have all properties
+   - Custom records (obsidian_vault, etc.) are present
+   - No validation errors in console
+
+## Conclusion
+
+✅ **The migration is safe and will not result in data loss.**
+
+- All document data is stored in R2, which is independent of Durable Object instances
+- Both classes use the same R2 bucket and storage path
+- The stub class ensures compatibility during migration
+- Format conversion logic preserves all data types
+- Room IDs can be recovered from URL paths if needed
+
+The only data that will be lost is the cached `roomId` in Durable Object storage, which can be easily re-initialized from the URL path.
