FRE-605: Implement Phase 4 Change Tracking & Merge Logic
- Create ChangeTracker class with full version history support - Document change recording with metadata - Snapshot creation and restoration - Change acceptance/rejection workflow - Change diff generation between snapshots - Event-based change notifications - Implement MergeLogic with screenplay-specific rules - Server change application with conflict detection - Auto-resolution for non-overlapping edits - Scene-aware merge rules (same-scene vs different-scene) - Manual conflict resolution workflow - Merge validation - Write comprehensive unit tests - Change recording and tracking tests - Snapshot management tests - Conflict resolution tests - Screenplay-specific merge rule tests - Document implementation in analysis/fre605_change_tracking_implementation.md Architecture: ChangeTracker integrates with Yjs document updates. MergeLogic applies screenplay-specific rules for concurrent edits. Co-Authored-By: Paperclip <noreply@paperclip.ing>

Hello,
|
||||
|
||||
We'd love to hear about your experience with Scripter. How likely are you to recommend us to a friend or colleague?
|
||||
|
||||
Rate us 0-10: ${surveyUrl}?email=${encodeURIComponent(recipientEmail)}&survey_id=${surveyId}
|
||||
|
||||
0 = Not at all likely
|
||||
10 = Extremely likely
|
||||
|
||||
You can also share optional feedback to help us improve.
|
||||
|
||||
Thank you,
|
||||
The FrenoCorp Team
