### 2. `compiler_activation_jobs.go` - Score: 78/100 ✅

**Rating**: Good | **Size**: 799 lines | **Test Coverage**: 0.58 ratio

#### Scores Breakdown

| Dimension | Score | Rating |
|-----------|-------|--------|
| Structure & Organization | 18/25 | Good |
| Readability | 15/20 | Good |
| Error Handling | 19/20 | Excellent |
| Testing & Maintainability | 15/20 | Good |
| Patterns & Best Practices | 11/15 | Good |
| **Total** | **78/100** | **Good** |

#### ✅ Strengths

1. **Excellent Error Handling**
   - Consistent use of `fmt.Errorf` with `%w` wrapper
   - Detailed validation error messages
   - Clear error context in all returns

2. **Clear Job Generation Logic**
   - Separate functions for each job type
   - Well-structured step generation
   - Good use of helper functions

3. **Comprehensive Documentation**
   - 162 comment lines (20% comment density)

#### ⚠️ Issues Identified

1. **File Size** (Medium Priority)
   - **Current**: 799 lines (approaching ideal limit)
   - **Recommendation**: Consider splitting into 3 focused files:
     - `compiler_pre_activation_job.go`
     - `compiler_activation_job.go`
     - `compiler_main_job.go`
   - **Estimated effort**: 2-3 hours

2. **Function Complexity** (Low Priority)
   - `buildPreActivationJob()` handles multiple concerns
   - Some conditional logic is deeply nested
   - Consider extracting helper functions for step generation

#### 💡 Recommendations

1. Split file into smaller, focused modules
2. Extract step generation logic into helper functions
3. Reduce nesting in conditional logic

### 3. `compiler_orchestrator.go` - Score: 95/100 ✅

**Rating**: Excellent | **Size**: 8 lines | **Purpose**: Shared logger

#### Scores Breakdown

| Dimension | Score | Rating |
|-----------|-------|--------|
| Structure & Organization | 25/25 | Excellent |
| Readability | 20/20 | Excellent |
| Testing & Maintainability | 20/20 | Excellent |
| Patterns & Best Practices | 15/15 | Excellent |
| **Total** | **95/100** | **Excellent** |

#### ✅ Strengths

1. **Perfect Design Pattern**
   - Single responsibility: Shared logger declaration
   - Minimal code for maximum clarity
   - Follows Go conventions for package-level loggers

2. **Clear Documentation**
   - Comment explains purpose clearly
   - Package imports are clean

3. **Best Practice**
   - Uses structured logger with namespace: `workflow:detection`
   - Allows orchestrator modules to share logger instance
   - Zero complexity, zero maintenance burden

#### 💡 Observations

This is an **example of excellent code organization**. Rather than duplicating logger declarations across multiple orchestrator files, it provides a single shared instance.

**Why This Works:**
- Single responsibility
- Clear purpose
- No business logic
- Zero maintenance burden
