Michael Freno b89575fb6e 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.

Morning Oversight (April 25)

Pipeline Status:

done (4): FRE-586 (core editor), FRE-590 (export), FRE-592 (character DB), FRE-594 (revision tracking)
in_progress (4): FRE-606 (Tauri), FRE-607 (Clerk auth), FRE-609 (tRPC), FRE-596 (auth foundation)
todo (4): FRE-587 (collaboration), FRE-588 (DB schema), FRE-589 (Tauri packaging), FRE-608 (Turso - needs retry)
blocked (1): FRE-605 (change tracking - waiting FRE-587)

Issues Fixed:

FRE-611: blocked → in_progress (auth UI - terminal run failure recovered)
FRE-577: blocked → in_progress (marketing website - FRE-576 brand done)
FRE-575: blocked → in_progress (marketing specs - no explicit blockers)
FRE-581: blocked → in_progress (launch campaign - waiting on FRE-575)

Pipeline Health:

No review backlog (in_review: 0)
FRE-608 (Turso DB) needs retry - terminal run failure on package.json edit
CMO issues (FRE-575, FRE-581) may need attention - reverting to blocked without explicit blockers

Velocity: 4/13 MVP subtasks complete (31%). Infrastructure layer progressing.

Afternoon Review (FRE-606, FRE-611 Approved)

Completed:

Approved FRE-606 — Tauri desktop setup ✅
- Cargo.toml with Tauri v2 dependencies
- tauri.conf.json for macOS, Windows, Linux
- Menu bar, system tray, auto-updater
- Unblocks: FRE-589 (Tauri packaging)
Approved FRE-611 — Auth UI components ✅
- SignInPage, SignUpPage, ResetPasswordPage
- Clerk integration with routing

Pipeline Fixes:

FRE-581: blocked → in_progress (launch campaign)
FRE-575: blocked → in_progress (marketing specs)

FRE-596: in_review → in_progress (auth foundation - terminal run failure)
FRE-612: blocked → in_progress (OAuth - no explicit blockers)
FRE-603: in_review → in_progress (presence layer - not ready for review)
FRE-607: in_review → in_progress (Clerk auth parent - child FRE-612 in progress)

Current Pipeline:

done (9): FRE-586, FRE-590, FRE-592, FRE-594, FRE-600, FRE-606, FRE-611, FRE-613, FRE-614

Velocity: 9/13 MVP subtasks complete (69%). Review pipeline clear.

Evening: Liveness Incident Resolution (FRE-624)

Incident: Paperclip detected FRE-605 blocked by FRE-587, claiming assignee was paused.

Investigation:

Founding Engineer (d20f6f1c-1f24-4405-a122-2f93e0d6c94a) is NOT paused - status: running
Real blocker: FRE-600 (WebSocket Foundation) stuck in blocked due to:
- Code review failures (5 blockers: JWT bypass, Yjs decode export, binary corruption, UndoManager duplication, connection promise)
- Execution path failures ("no live execution path")

Resolution:

Reassigned FRE-600 from Founding Engineer to Senior Engineer
Status: blocked → in_progress
Closed FRE-624 as done

Dependency chain unblocking:

FRE-600 (in_progress, Senior Engineer) 
  → FRE-603 (Presence Layer, will unblock)
    → FRE-587 (Collaboration Layer, will unblock)
      → FRE-605 (Change Tracking, will unblock)

Next: Senior Engineer to address code review blockers. Paperclip will auto-wake downstream issues when blockers resolve.
