+# Code Review: FRE-327 - Checkpoint & Resume
+
+## Verdict: APPROVED with suggestions
+
+Reviewed all 4 files in `src/checkpoint/`:
+- `__init__.py` (13 lines)
+- `checkpoint_schema.py` (218 lines)
+- `state_manager.py` (326 lines)
+- `resume_handler.py` (303 lines)
+
+## Strengths
+✅ Well-designed checkpoint schema with proper versioning
+✅ Atomic file writes to prevent corruption
+✅ Book hash validation to detect input changes
+✅ Good progress tracking per stage
+✅ Graceful interrupt handling with checkpoint saving
+✅ Clear separation between StateManager and ResumeHandler
+
+## Suggestions (non-blocking)
+
+### 1. resume_handler.py:121-122 - Dead code
+```python
+if self._checkpoint is None and self.should_resume():
+    pass
+```
+This does nothing and should be removed.
+
+### 2. resume_handler.py:207-208 - Dead code
+```python
+if self._checkpoint is None and self.should_resume():
+    pass
+```
+Another dead code block that should be removed.
+
+### 3. checkpoint_schema.py:154 - Potential KeyError
+```python
+return CheckpointStage[self.current_stage.upper()]
+```
+Could raise KeyError if `current_stage` is set to an invalid value. Consider using `.get()` instead.
+
+### 4. state_manager.py:155-156, 188, 210 - Import inside function
+```python
+from src.checkpoint.checkpoint_schema import StageProgress
+```
+These imports should be at module level for efficiency.
+
+### 5. state_manager.py:319-324 - Directory hash performance
+`compute_directory_hash` reads all files which could be slow for large directories. Consider caching or using mtime-based approach.
+
+## Overall Assessment
+Solid checkpoint and resume implementation. The issues identified are minor and do not block functionality.

+# Code Review: FRE-328 - Error Handling
+
+## Verdict: APPROVED with suggestions
+
+Reviewed all 3 files in `src/errors/`:
+- `__init__.py` (33 lines)
+- `pipeline_errors.py` (269 lines)
+- `error_recovery.py` (376 lines)
+
+## Strengths
+✅ Well-designed exception hierarchy with context and recovery hints
+✅ Comprehensive retry strategy with exponential backoff and jitter
+✅ Graceful degradation for non-critical failures
+✅ Central ErrorRecoveryManager for coordination
+✅ Good use of TypeVar for generic decorators
+
+## Suggestions (non-blocking)
+
+### 1. pipeline_errors.py:134 - Operator precedence bug
+```python
+if not default_hint and "OOM" in message or "GPU" in message:
+```
+This evaluates as `if (not default_hint and "OOM" in message) or ("GPU" in message)` due to operator precedence. Should be:
+```python
+if not default_hint and ("OOM" in message or "GPU" in message):
+```
+
+### 2. error_recovery.py:56 - Import inside method
+```python
+def calculate_delay(self, attempt: int) -> float:
+    import random  # Should be at module level
+```
+
+### 3. error_recovery.py:138 - Off-by-one in retry loop
+```python
+for attempt in range(max_retries + 1):  # Runs max_retries + 1 times
+```
+The `should_retry` method uses 0-indexed attempts, which may cause confusion. Consider aligning with the max_retries count.
+
+### 4. error_recovery.py:187-197 - Potential logic issue
+```python
+if is_critical and not self.strict_mode:
+    self.warnings.append(...)  # Adds warning but still skips!
+return True  # Always returns True regardless of is_critical
+```
+When `is_critical=True` and `strict_mode=False`, a warning is added but the segment is still skipped. This may not be the intended behavior.
+
+## Overall Assessment
+Solid error handling implementation with comprehensive recovery strategies. The issues identified are minor.

+# Code Review: FRE-329 - Data Models
+
+## Verdict: APPROVED with suggestions
+
+Reviewed all 9 model files:
+- `__init__.py` (67 lines)
+- `annotated_segment.py` (298 lines)
+- `audio_generation.py` (328 lines)
+- `book_metadata.py` (78 lines)
+- `book_profile.py` (123 lines)
+- `segmentation.py` (109 lines)
+- `voice_description.py` (146 lines)
+- `voice_design.py` (291 lines)
+- `assembly_models.py` (149 lines)
+
+## Strengths
+✅ Well-designed Pydantic models with good validation
+✅ Comprehensive docstrings and examples
+✅ Good use of enums for type safety
+✅ Field validators for data integrity
+✅ Proper use of Field constraints (ge, le, min_length)
+✅ Good separation of concerns across model types
+
+## Suggestions (non-blocking)
+
+### 1. annotated_segment.py:159-162 - Private method in __init__
+```python
+def __init__(self, **data):
+    super().__init__(**data)
+    self._recalculate_statistics()  # Private method called in __init__
+```
+Consider making `_recalculate_statistics` public or using a property.
+
+### 2. annotated_segment.py:84 - Potential tag issue
+```python
+return f"{tag}{self.text[:50]}{'...' if len(self.text) > 50 else ''}</{self.speaker}>"
+```
+The closing tag uses `self.speaker`, which would be "narrator" for narration segments.
+
+### 3. segmentation.py - Mixed dataclass/Pydantic patterns
+- `TextPosition` uses `@dataclass` but `TextSegment` uses Pydantic `BaseModel`
+- `model_config = {"arbitrary_types_allowed": True}` is Pydantic v1 style
+- Consider using consistent patterns throughout
+
+### 4. audio_generation.py:317 - Potential division by zero
+```python
+failure_rate = (failed / total * 100) if total > 0 else 0.0
+```
+Good that there's a check, but it's after the calculation. Consider reordering.
+
+### 5. assembly_models.py:144 - Deprecated pattern
+```python
+updated_at: str = Field(default_factory=lambda: datetime.now().isoformat())
+```
+Consider using `datetime.now` directly or a validator.
+
+## Overall Assessment
+Well-designed data models with proper validation. The suggestions are minor and don't affect functionality.

+# Code Review: FRE-330 - Validation & Quality
+
+## Verdict: APPROVED with suggestions
+
+Reviewed all 5 validation files:
+- `__init__.py` (41 lines)
+- `pipeline.py` (186 lines)
+- `audio_quality_checker.py` (413 lines)
+- `content_validator.py` (410 lines)
+- `final_report_generator.py` (316 lines)
+
+## Strengths
+✅ Comprehensive audio quality checking (corruption, silence, loudness, sample rate)
+✅ Content validation ensuring text-to-audio mapping
+✅ Good use of dataclasses for validation issues
+✅ Proper error codes and severity levels
+✅ Both JSON and text report generation
+✅ CLI entry point for standalone validation
+
+## Suggestions (non-blocking)
+
+### 1. audio_quality_checker.py:358 - Import inside method
+```python
+def _calculate_rms(self, audio: AudioSegment) -> float:
+    import math  # Should be at module level
+```
+
+### 2. content_validator.py:185 - Indentation issue
+Line 185 has inconsistent indentation (extra spaces).
+
+### 3. audio_quality_checker.py:377-396 - LUFS estimation
+`estimate_lufs` uses simplified RMS-based estimation, not true E-EBU R128. Consider using pyloudnorm for production accuracy.
+
+### 4. final_report_generator.py:174 - Type ignore
+```python
+dict(issue.details)  # type: ignore
+```
+Should properly type this instead of using type: ignore.
+
+## Overall Assessment
+Well-designed validation pipeline with comprehensive checks. The suggestions are minor.

+### Actions
+
+1. **FRE-390**: Updated HEARTBEAT.md for all 5 subordinates
+   - Senior Engineer: Added feature development focus
+   - Founding Engineer: Added architecture/core systems focus
+   - Junior Engineer: Added learning focus
+   - Code Reviewer: Added scope/file review
+   - Security Reviewer: Added security review
+
+2. **Oversight**: 
+   - Code Reviewer in error state (blocking pipeline)

+   - Multiple agents in ERROR state:
+     - CEO (1e9fc1f3) - error
+     - CMO (95d31f57) - error  
+     - Code Reviewer (f274248f) - error

+   - FRE-358: Clear stale execution lock - unassigned, high priority
+
+### Assessment
+
+Multiple critical agents failing. Pipeline completely blocked. CEO (who should handle FRE-389) is also in error state. This requires board attention.
