## Completed Steps
- Initialized briefing and original request tracker files.
- Investigated `reversecore_mcp/tools/analysis/lief_tools.py` and existing tests.
- Replaced context manager `with` for `ProcessPoolExecutor` with manual lifecycle management in `parse_binary_with_lief`.
- Terminated and joined all executor subprocesses explicitly on `TimeoutError`.
- Called `.shutdown()` with appropriate arguments depending on exit conditions (success, timeout, BrokenProcessPool, and other exceptions).
- Added comprehensive unit tests in `tests/unit/tools/analysis/test_lief_tools.py` to cover:
  - Mock process termination verification on timeout.
  - Shutdown calls with correct options for success, broken pool, and other exceptions.
- Ran tests and confirmed 100% success (34 tests passed) and 98% coverage on `lief_tools.py`.
- Verified formatting and linting (ruff, black) on the affected files.

## Next Steps
- Review unit tests execution results for all unit tests.
- Write handoff report `handoff.md`.
