# Forensic Audit & Handoff Report

## Forensic Audit Report

**Work Product**: `reversecore_mcp/tools/analysis/lief_tools.py` and `tests/unit/tools/analysis/test_lief_tools.py`
**Profile**: General Project
**Verdict**: CLEAN

### Phase Results
- **Hardcoded output detection**: PASS — Checked source code, verified no hardcoded outputs, test result formats, or shortcut strings.
- **Facade detection**: PASS — Verified functions contain genuine logic (LIEF alias compatibility, ProcessPoolExecutor handling, limit validation, and metadata extraction).
- **Pre-populated artifact detection**: PASS — No pre-populated logs or artifacts are used by or required for the target lief_tools execution.
- **Behavioral Verification**: PASS — Unit test suite executes and passes successfully, achieving 98% coverage for `lief_tools.py`.
- **Dependency Audit**: PASS — Uses expected `lief` library for LIEF-based binary analysis wrapper.
- **Layout Compliance**: PASS — All agent files are restricted to metadata, and target source/test files are in their correct locations.

## 5-Component Handoff Report

### 1. Observation
- **Target Files**:
  - Implementation: `reversecore_mcp/tools/analysis/lief_tools.py`
  - Tests: `tests/unit/tools/analysis/test_lief_tools.py`
- **Git Diffs**:
  - `reversecore_mcp/tools/analysis/lief_tools.py` had compatibility aliases added at lines 48-73 for newer LIEF versions (e.g. `lief.ELF.DYNAMIC_TAGS`, `lief.PE.DLL_CHARACTERISTICS`).
  - Corrected `ProcessBrokenExecutor` (which is non-existent in Python) to `BrokenProcessPool` at line 358.
  - Robust worker process termination added on timeout inside `ProcessPoolExecutor`:
    ```python
    except concurrent.futures.TimeoutError:
        try:
            for p in list(executor._processes.values()):
                p.terminate()
                p.join(timeout=1.0)
        except Exception:
            pass
        executor.shutdown(wait=False, cancel_futures=True)
    ```
- **Test Executions**:
  - Running command: `pytest tests/unit/ -v`
  - Results verbatim: `1569 passed, 8 skipped in 23.64s`.
  - Coverage for `reversecore_mcp/tools/analysis/lief_tools.py` is `98%` (219 statements, 4 missed).

### 2. Logic Chain
- **Step 1**: The git diffs show that changes were made specifically to fix robust exception handling (fixing class name `ProcessBrokenExecutor` to `BrokenProcessPool` and ensuring subprocess cleanup on timeout) and adding aliases for newer LIEF library versions. This is genuine robustness logic.
- **Step 2**: Running the unit tests verified that `lief_tools.py` tests pass and cover 98% of the source statements. This is far above the target coverage requirement of 75%.
- **Step 3**: Examining the source code confirms there is no bypass condition or hardcoded expected result that intercepts calls. All functions execute standard python/LIEF API calls.
- **Conclusion**: The implementation is authentic, correct, and robust.

### 3. Caveats
- The unit test suite mock-tests LIEF objects using `unittest.mock.MagicMock` to bypass the need for a compiled C++ LIEF installation in standard CI/CD environments. While this fulfills the user requirement for isolated unit testing, behavior on real malformed binaries was not dynamically tested with lief, though the code's crash-handling wrapper ensures that any C++ crashes or hangs will be caught as `CRASH_DETECTED` or `TIMEOUT`.

### 4. Conclusion
- The target implementation in `reversecore_mcp/tools/analysis/lief_tools.py` is authentic, clean, and correctly tested. The coverage meets the criteria at 98%, and no cheat codes exist.

### 5. Verification Method
- **Command**:
  ```bash
  pytest tests/unit/tools/analysis/test_lief_tools.py --cov=reversecore_mcp/tools/analysis/lief_tools.py --cov-report=term-missing
  ```
- **Files to Inspect**:
  - `reversecore_mcp/tools/analysis/lief_tools.py`
  - `tests/unit/tools/analysis/test_lief_tools.py`
