LOCK-FREE MIGRATION - OVERNIGHT RUN SUMMARY

Date: October 28, 2025 Status: Phase 2 Complete, Moving to Compilation

AUTOMATED MIGRATION RESULTS

Phase 2: ObjectAccessor Fallback Removal

Automated Script Results:

Files Processed: 20 files
Fallbacks Removed: 64 locations
Lines Changed: ~212 lines
Cell::Visit Replaced: 2 (CombatSpecializationBase.cpp)

Files Successfully Migrated:

✅ ClassAI.cpp
✅ ClassAI_Refactored.cpp
✅ CombatSpecializationBase.cpp (+ 2 Cell::Visit replacements)
✅ BotThreatManager.cpp (6 fallbacks)
✅ AoEDecisionManager.cpp
✅ DefensiveBehaviorManager.cpp
✅ DispelCoordinator.cpp (2 fallbacks)
✅ InterruptRotationManager.cpp (2 fallbacks)
✅ LootStrategy.cpp (2 fallbacks)
✅ QuestStrategy.cpp (3 fallbacks)
✅ DeathKnightAI.cpp (2 fallbacks)
✅ DemonHunterAI.cpp (2 fallbacks)
✅ EvokerAI.cpp (1 fallback)
✅ HunterAI.cpp (3 fallbacks)
✅ MonkAI.cpp (6 fallbacks)
✅ PaladinAI.cpp (4 fallbacks)
✅ RogueAI.cpp (2 fallbacks)
✅ ShamanAI.cpp (19 fallbacks - largest!)
✅ WarlockAI.cpp (2 fallbacks)
✅ WarriorAI.cpp (2 fallbacks)

Remaining Work:

ObjectAccessor Calls: ~30 actual code locations (68 grep hits but many are comments) Cell::Visit Calls: 38 locations

Files Needing Manual Attention:

BotAI_EventHandlers.cpp (6 calls)
InterruptAwareness.cpp (error during automation)
Action.cpp, SpellInterruptAction.cpp
CombatBehaviorIntegration.cpp
CombatStateAnalyzer.cpp
GroupCombatTrigger.cpp
InterruptManager.cpp
KitingManager.cpp
LineOfSightManager.cpp
ObstacleAvoidanceManager.cpp
PositionManager.cpp
TargetSelector.cpp
ThreatCoordinator.cpp

NEXT STEPS

Immediate: Phase 6 - Compilation

Goal: Identify what actually breaks from the 64 removals Expected: Some compilation errors due to removed variable usage

After Compilation:

Fix compilation errors from removed ObjectAccessor calls
Handle remaining manual migrations as needed
Final validation

MIGRATION PATTERNS APPLIED

Pattern 1: Simple Fallback Removal (Most Common)

Before:

auto snapshot = SpatialGridQueryHelpers::FindCreatureByGuid(_bot, guid);
if (!snapshot || !snapshot->IsAlive())
    continue;

Unit* target = ObjectAccessor::GetUnit(*_bot, guid);  // ❌ REMOVED
if (!target)
    continue;

DoSomething(target);

After:

auto snapshot = SpatialGridQueryHelpers::FindCreatureByGuid(_bot, guid);
if (!snapshot || !snapshot->isAlive)
    continue;

// Use snapshot directly - no pointer needed!
DoSomethingWithSnapshot(*snapshot);

Pattern 2: Cell::Visit Replacement

Before (CombatSpecializationBase.cpp):

std::vector<::Unit*> GetNearbyEnemies(float range) const
{
    std::vector<::Unit*> enemies;
    Cell::VisitGridObjects(_bot, searcher, range);  // ❌ REMOVED
    return enemies;
}
