## Technical Pattern Applied

All 4 phases followed the same rigorous 5-step pattern:

### Step 1: Interface Creation
```cpp
// Pattern: src/modules/Playerbot/Core/DI/Interfaces/I{ServiceName}.h
class TC_GAME_API I{ServiceName}
{
public:
    virtual ~I{ServiceName}() = default;

    // All public methods as pure virtual
    virtual ReturnType MethodName(params) = 0;
};
```

### Step 2: Implementation Modification
```cpp
// Add interface include
#include "../Core/DI/Interfaces/I{ServiceName}.h"

// Inherit from interface
class TC_GAME_API {ServiceName} final : public I{ServiceName}
{
public:
    static {ServiceName}* instance();

    // Add override keywords to all interface methods
    ReturnType MethodName(params) override;
};
```

### Step 3: ServiceRegistration.h Update
```cpp
// Add interface include
#include "Interfaces/I{ServiceName}.h"

// Add implementation include
#include "{Path}/{ServiceName}.h"

// In RegisterPlayerbotServices():
container.RegisterInstance<I{ServiceName}>(
    std::shared_ptr<I{ServiceName}>(
        Playerbot::{ServiceName}::instance(),
        [](I{ServiceName}*) {} // No-op deleter (singleton)
    )
);
TC_LOG_INFO("playerbot.di", "  - Registered I{ServiceName}");
```

### Step 4: MIGRATION_GUIDE.md Update
- Increment version (4.1 → 4.2 → 4.3 → 4.4)
- Add service to migration table
- Update progress count (47 → 48 → 49 → 50)
- Update percentage (28.0% → 28.6% → 29.2% → 29.8%)

### Step 5: Commit and Push
```bash
git add -A
git commit -m "feat(playerbot): Implement Dependency Injection Phase {N} ({ServiceName})"
git push -u origin claude/playerbot-improvements-011CUpjXEHZWruuK7aDwNxnB
```

## Continuation Checklist for Next Session

### ✅ Verify Environment
```bash
cd /home/user/TrinityCore
git status  # Should be clean
git log --oneline -5  # Verify Phase 35 pushed
```

### ✅ Continue Migration Pattern
1. Select next singleton from recommendations or search:
   ```bash
   grep -r "static.*instance()" src/modules/Playerbot --include="*.h" | grep -v "Interfaces/"
   ```

2. Read candidate file:
   - Count public methods
   - Check for complex structures (atomics, mutexes)
   - Estimate interface complexity

3. Follow 5-step pattern for each phase
4. Commit and push after each phase
5. Update this handover document

### ✅ Quality Standards
- Zero compilation errors
- All override keywords applied
- Thread-safe mutex patterns preserved
- Backward compatibility maintained
- Clear commit messages with comprehensive details

### ✅ Token Budget Management
- Monitor token usage (aim for <190k)
- Create handover document before 190k
- Larger singletons (50+ methods) use more tokens
- Plan phases to maximize progress within budget

---

## Session Context Preserved

**User Directive**: "Continue implementation without any stop"

The user explicitly requested continuous implementation until token budget approaches 190k, then prepare handover document. This session followed that directive, completing 4 phases efficiently within token budget.

**Branch Requirements**:
- Branch must start with `claude/` and end with session ID
- Push using: `git push -u origin <branch-name>`
- Retry on network errors with exponential backoff

**No Breaking Changes**: All migration work maintains 100% backward compatibility through dual-access pattern (singleton + DI access both work).

## Quick Reference: Migration Commands

```bash
# Create interface
# File: src/modules/Playerbot/Core/DI/Interfaces/I{Name}.h

head -100 src/modules/Playerbot/{Path}/{Name}.h

# Edit implementation
# 1. Add interface include
# 2. Inherit from interface: final : public I{Name}
# 3. Add override keywords to all methods

# Update ServiceRegistration.h
# 1. Add interface include at top
# 2. Add implementation include
# 3. Add registration in RegisterPlayerbotServices()

# Update MIGRATION_GUIDE.md
# 1. Increment version
# 2. Add to table
# 3. Update progress count and percentage

# Commit
git add -A && git commit -m "feat(playerbot): Implement Dependency Injection Phase {N} ({Name})"

# Push with retry
git push -u origin claude/playerbot-improvements-011CUpjXEHZWruuK7aDwNxnB
```
