## Code Quality Section (ln-624)

### Applied Fixes

| ID | File | Line | Category | Finding | Status |
|----|------|------|----------|---------|--------|
| MNT-DC-001 | `src/codomyrmex/audio/mcp_tools.py` | 3 | unsorted-imports (I001) | `mcp_tool` import before `typing.Any` | **FIXED** |
| MNT-DC-002 | `src/codomyrmex/tests/unit/audio/test_mcp_tools.py` | 143 | missing-newline (W292) | No newline at end of file | **FIXED** |
| MNT-DC-003 | `src/codomyrmex/tests/unit/examples/test_fastapi_endpoint_example.py` | 1 | unsorted-imports (I001) | Mixed import block ordering | **FIXED** |

### Skipped Findings

| ID | File | Lines | Category | Reason for Skip |
|----|------|-------|----------|-----------------|
| MNT-DC-004 | `src/codomyrmex/tests/unit/agents/test_react_agent.py` | 76–80 | commented-out-code | 5-line block is explanatory documentation showing impl under test; confidence 75% (<90% threshold) |

### Evaluated — Not Dead Code

| File | Pattern Matched | Reason Not Dead |
|------|----------------|-----------------|
| `model_context_protocol/compat.py` | "compat" in name | Active shim *generator* utility; consumed by MCP layer |
| `api/standardization/api_versioning.py` | `_deprecated_version` attr | Marks API endpoints as deprecated — active feature |
| `api/rate_limiting/distributed.py` | `_clean_old_requests` method | Cleans expired rate-limit buckets — active logic |

---

## Backward-Compat & Legacy Section (ln-626)

No deprecated aliases or backward-compat wrapper functions found in production code.
`model_context_protocol/compat.py` generates shims on-demand but is not itself a legacy shim.
