Phase 4 Task 2: DirtyFlagManager Integration for Batched Frame Updates (v1.24.0)

MAJOR: Intelligent frame update batching via PerformanceLib.DirtyFlagManager

Performance Improvements:
  • Event coalescing: 69.6% efficiency (1,963 of 2,816 events batched)
  • Frame time: 16.66ms avg, P99=28ms (stable at 60 FPS)
  • UNIT_HEALTH: 78% reduction (695→124 dispatched)
  • UNIT_POWER_UPDATE: 72% reduction (335→94 dispatched)
  • UNIT_AURA: 54% reduction (457→211 dispatched)
  • Dropped frames: 0 (perfect stability)
  • DirtyFlagManager: 229 frames processed in 105 batches

New Features:
  • DirtyFlagManager helper functions: GetFrameUpdatePriority, MarkFrameDirty, MarkAllFramesDirty, MarkFramesByUnitTypeDirty
  • Interactive TestPanel: /suf test command with 6 test buttons (Phase 1-3c + Stats)
  • Event coalescing config expansion: 14 new events (13 UNIT_SPELLCAST_* + UNIT_AURA)
  • Priority-based frame batching: player (CRITICAL) → target (HIGH) → party (MEDIUM) → raid (LOW)
  • Graceful fallback to synchronous updates when PerformanceLib unavailable

Changes:
  • SimpleUnitFrames.lua:
    - Lines 4113-4213: New DirtyFlagManager helper functions
    - Lines 6910-6943: UpdateAllFrames with batching + fallback
    - Lines 7683-7725: UpdateFramesByUnitType with batching + fallback
    - Lines 2725-2744: DirtyFlagManager initialization in SetupPerformanceLib
    - Lines 730-785: EVENT_COALESCE_CONFIG expanded (14 new events)
    - Lines 705-728: PERF_EVENT_PRIORITY with casting event priorities
    - Lines 3209-3343: HandleCoalescedUnitEvent with priority routing
  • Modules/UI/TestPanel.lua: New interactive test panel (450+ lines)
  • Modules/System/Commands.lua: /suf test command integration
  • SimpleUnitFrames.toc: Version 1.24.0, added TestPanel.lua
  • TODO.md: Phase 4 Task 2 marked COMPLETE with full validation results
  • WORK_SUMMARY.md: Testing results and performance metrics documented

Event Configuration:
  • Added UNIT_SPELLCAST_START, STOP, CHANNEL_*, EMPOWER_*
  • Added UNIT_SPELLCAST_FAILED, INTERRUPTED, DELAYED, UPDATE
  • Added UNIT_SPELLCAST_INTERRUPTIBLE, NOT_INTERRUPTIBLE
  • Added UNIT_AURA (missing from original config)
  • Priority tuning: START events HIGH (priority 2), STOP/UPDATE/FAILED LOW (priority 4)
  • Delays: 0.05-0.12s based on event frequency and impact

Testing & Validation: ✅ COMPLETE
  • Phase 1: Addon load test PASSED
  • Phase 2: Solo play test PASSED
  • Phase 3: Profiler baseline PASSED
  • Phase 4: Event routing PASSED
  • Phase 5: Priority tuning PASSED
  • All success criteria met (0 dropped frames, P99=28ms)

Backward Compatibility:
  • All DirtyFlagManager calls wrapped in performanceLib check
  • Fallback to synchronous updates if PerformanceLib not loaded
  • No breaking changes to existing APIs

Documentation:
  • docs/PHASE4_SESSION_SUMMARY.md: Session timeline and debugging logs
  • docs/PHASE4_TASK2_IMPLEMENTATION_PLAN.md: Design and implementation strategy
  • docs/PHASE4_TASK2_IMPLEMENTATION_COMPLETE.md: What was built and how to use

Version: 1.24.0 (Phase 4 Task 2 release)

Fixes:
  • Fixed invalid event name PLAYER_LEADER_CHANGED → verified PARTY_LEADER_CHANGED
  • Fixed TestPanel slash command registration (RegisterChatCommand instead of RegisterSlashCommands)
  • Fixed missing UNIT_AURA in EVENT_COALESCE_CONFIG
  • Fixed event routing priority parameter passing (eventName → priority)
