-# V2 Database Service Integration Status
-
-## Overview
-The unified database service (DbService) has been successfully integrated into messageThunk.ts with feature flag support. This allows gradual rollout and easy rollback if issues occur.
-
-## Feature Flag Control
-```javascript
-// Enable V2 implementation
-VITE_USE_UNIFIED_DB_SERVICE=true yarn dev
-
-// Or via browser console
-localStorage.setItem('featureFlags', JSON.stringify({ USE_UNIFIED_DB_SERVICE: true }))
-location.reload()
-```
-

-
-- **updateMessage** → `updateMessageV2`
-  - Location: messageThunk.ts:1669
-  - Status: ✅ Integrated
-  - Used in updateMessageAndBlocksThunk
-
-## Not Yet Integrated
-
-### Functions Available but Not Used
-These V2 functions exist but haven't been integrated yet as their usage patterns are different:
-
-- **getRawTopicV2** - Available but not directly replacing db.topics.get() calls
-- **getTopicV2** - Available but not directly replacing db.topics.get() calls  
-- **persistExchangeV2** - Available for future use with message exchanges
-
-### Complex Operations Still Using Original Implementation
-These operations involve complex transactions and topic management that would need careful refactoring:
-
-1. **Topic message list updates** (db.topics.update with messages array)
-   - Used after delete operations
-   - Used in resendMessageThunk
-   - Used in regenerateAssistantMessageThunk
-   
-2. **Transaction-based operations**
-   - cloneMessagesToNewTopicThunk (partial integration)
-   - initiateTranslationThunk
-   - removeBlocksThunk
-
-## Testing Checklist
-
-### High Priority (Core Operations)
-- [x] Load messages for regular topic
-- [x] Load messages for agent session
-- [ ] Send message in regular chat
-- [ ] Send message in agent session
-- [ ] Delete single message
-- [ ] Delete message group
-- [ ] Clear all messages
-
-### Medium Priority (Edit Operations)
-- [ ] Update message content
-- [ ] Update message blocks
-- [ ] Update translation blocks
-- [ ] File reference counting
-
-### Low Priority (Advanced Features)
-- [ ] Clone messages to new topic
-- [ ] Resend messages
-- [ ] Regenerate assistant messages
-- [ ] Multi-model responses
-
-## Next Steps
-
-1. **Test Current Integrations**
-   - Enable feature flag and test all integrated operations
-   - Monitor for any errors or performance issues
-   - Verify data consistency
-
-2. **Phase 3 Consideration**
-   - Consider refactoring complex topic update operations
-   - Evaluate if persistExchangeV2 should be used for user+assistant pairs
-   - Plan migration of remaining db.topics operations
-
-3. **Performance Monitoring**
-   - Compare load times between original and V2
-   - Check memory usage with large message histories
-   - Verify agent session performance
-
-## Rollback Instructions
-If issues occur, disable the feature flag immediately:
-```javascript
-localStorage.setItem('featureFlags', JSON.stringify({ USE_UNIFIED_DB_SERVICE: false }))
-location.reload()
-```
-
-## Notes
-- All V2 implementations maintain backward compatibility
-- Agent session operations (IPC-based) are handled transparently
-- File operations only apply to Dexie storage, not agent sessions
-- Feature flag allows gradual rollout and A/B testing

-# Rollback Strategy for Unified Database Service Migration
-
-## Overview
-This document outlines the rollback procedures for the unified database service migration. The migration uses feature flags to enable gradual rollout and quick rollback capabilities.
-
-## Quick Rollback (< 1 minute)
-
-### Via Browser Console
-```javascript
-// Disable the unified DB service immediately
-localStorage.setItem('featureFlags', JSON.stringify({ USE_UNIFIED_DB_SERVICE: false }))
-location.reload()
-```
-
-### Via Code (Emergency)
-```typescript
-// In src/renderer/src/config/featureFlags.ts
-export const featureFlags: FeatureFlags = {
-  USE_UNIFIED_DB_SERVICE: false  // Change from true to false
-}
-```
-
-## Rollback Triggers
-
-Monitor these indicators to determine if rollback is needed:
-
-### Critical Issues (Immediate Rollback)
-- [ ] Data loss or corruption
-- [ ] Application crashes on startup
-- [ ] Complete failure to load messages
-- [ ] Agent sessions completely broken
-- [ ] Performance degradation > 50%
-
-### Major Issues (Rollback within 1 hour)
-- [ ] Intermittent message loading failures (> 10% error rate)
-- [ ] Memory leaks detected
-- [ ] Performance degradation 20-50%
-- [ ] File upload/attachment issues
-- [ ] Message editing/deletion not working
-
-### Minor Issues (Consider Rollback)
-- [ ] Performance degradation < 20%
-- [ ] UI glitches or inconsistencies
-- [ ] Non-critical features affected
-- [ ] Increased error logs but functionality intact
-
-## Rollback Procedures
-
-### Level 1: Feature Flag Toggle (Immediate)
-**When:** Any critical issue detected
-**Time:** < 1 minute
-**Data Impact:** None
-
-1. Set feature flag to false:
-   ```javascript
-   localStorage.setItem('featureFlags', JSON.stringify({ USE_UNIFIED_DB_SERVICE: false }))
-   ```
-2. Reload application
-3. Verify original functionality restored
-4. Alert team about rollback
-
-### Level 2: Code Revert (Quick)
-**When:** Feature flag not sufficient or broken
-**Time:** < 5 minutes
-**Data Impact:** None
-
-1. Revert to previous commit:
-   ```bash
-   git revert HEAD  # If just deployed
-   # or
-   git checkout <last-known-good-commit>
-   ```
-2. Rebuild and deploy:
-   ```bash
-   yarn build:check
-   yarn build
-   ```
-3. Test core functionality
-4. Document issue for investigation
-
-### Level 3: Full Rollback (Planned)
-**When:** Systemic issues discovered
-**Time:** 30 minutes
-**Data Impact:** Potential data migration needed
-
-1. Notify all stakeholders
-2. Export any critical data if needed
-3. Restore from backup branch:
-   ```bash
-   git checkout main
-   git branch -D feature/unified-db-service
-   git push origin --delete feature/unified-db-service
-   ```
-4. Clean up any migration artifacts:
-   - Remove `messageThunk.v2.ts`
-   - Remove `src/renderer/src/services/db/` if created
-   - Remove feature flags configuration
-5. Run full test suite
-6. Deploy clean version
-
