## Mission
Review the LIEF tool bug fix and compatibility mappings to ensure correctness, robustness, and that unit tests pass successfully.

## Review Scope
- **Files to review**: `reversecore_mcp/tools/analysis/lief_tools.py`, `tests/unit/tools/analysis/test_lief_tools.py`
- **Interface contracts**: `PROJECT.md` or `AGENTS.md`
- **Review criteria**: Correctness of `BrokenProcessPool` exception typo (ProcessBrokenExecutor?), compatibility mapping for LIEF properties, and robustness of unit tests.

## Key Decisions Made
- Determined that the ProcessBrokenExecutor fix is correct.
- Verified that LIEF compatibility mappings are correct and necessary for LIEF 0.14+.
- Discovered a critical timeout hang vulnerability in the ProcessPoolExecutor context manager pattern and proposed a mitigation.

## Review Checklist
- **Items reviewed**: `reversecore_mcp/tools/analysis/lief_tools.py`, `tests/unit/tools/analysis/test_lief_tools.py`
- **Verdict**: REQUEST_CHANGES (due to the critical timeout hang vulnerability)
- **Unverified claims**: None. All claims verified.

## Attack Surface
- **Hypotheses tested**:
  - Does the ProcessPoolExecutor context manager block on exit if a task hangs and times out? (Result: YES, hangs indefinitely).
  - Can we import `BrokenProcessPool` from `concurrent.futures.process`? (Result: YES).
  - Can we write to `lief.ELF` attributes? (Result: YES).
- **Vulnerabilities found**:
  - Timeout hang vulnerability: ProcessPoolExecutor `with` statement blocks indefinitely on exit when waiting for a hung worker thread/process.
- **Untested angles**: None.
