**Files Reviewed**: 3 orchestration files
**Scope**: WorkflowOrchestrator, ServiceWatchdog, lifecycle management

______________________________________________________________________

## Executive Summary

**Overall Status**: ✅ **EXCELLENT** (98/100) - Production-ready

**Compliance Scores**:

- Architecture: 100% ✅ (Perfect)
- Code Quality: 98/100 ✅ (Excellent)
- Security: 100% ✅ (Perfect)
- Documentation: 80/100 ⚠️ (Some gaps)

## Architecture Compliance (Score: 100%)

### ✅ PERFECT Framework Design

**Oneiric Workflow Builder** (`oneiric_workflow.py`, lines 184-279):

```python
def _build_workflow_dag(
    self,
    options: OptionsProtocol,
    job_id: str,
) -> dict[str, Task]:
    """Build workflow DAG with optional parallel phase execution."""
    tasks = {
        "config_load": Task(
            name="Configuration Loading",
            fn=self._load_configuration,
            depends_on=[],
        ),
        # ... proper DAG construction
    }
```

**Key Strengths**:

- Framework-agnostic design
- Clean task dependencies
- Proper parallel phase support
- No direct crackerjack imports

**Health Snapshot** (`health_snapshot.py`, lines 11-68):

- Simple dataclass with JSON serialization
- 69 lines total (minimal, focused)
- Proper type safety

## Code Quality (Score: 98/100)

### ✅ EXCELLENT DAG Construction

**Parallel Phase Support** (lines 242-279):

```python
if options.enable_parallel_phases:
    # Tests and comprehensive hooks run in parallel
    tasks["tests"].depends_on = ["fast_hooks"]
    tasks["comprehensive_hooks"].depends_on = ["fast_hooks"]
    # NOT: ["tests"] - enables parallel execution
```

**Quality**: Clean dependency graph manipulation

### ⚠️ ONE MINOR ISSUE

**Disabled Feature** (line 289):

```python
# TODO: Should we run config cleanup in comprehensive phase?
def _should_run_config_cleanup(self, options: OptionsProtocol) -> bool:
    return False  # Currently disabled
```

**Recommendation**: Document why disabled or file tracking issue

______________________________________________________________________

## Security (Score: 100%)

### ✅ PERFECT Security

- **No subprocess usage**
- **No credential handling**
- **Safe JSON parsing** with exception handling
- **No hardcoded paths**

______________________________________________________________________

## Priority Recommendations

### 🟢 LOW (Documentation)

**1. Document Disabled Feature**

- **File**: `oneiric_workflow.py:289`
- **Action**: Add comment explaining why config cleanup is disabled
- **Effort**: 15 minutes

**2. Add Runtime Health Validation**

- **Action**: Check if snapshot data is consistent
- **Effort**: 2 hours

**3. Add Integration Tests**

- **Focus**: Parallel phase DAG construction
- **Effort**: 3 hours
