# BRIEFING — 2026-06-26T22:29:15Z

## Mission
Empirically stress test correctness and exception pathways of the patch explainer tools in `reversecore_mcp/tools/common/patch_explainer.py`.

## 🔒 My Identity

- Milestone: Milestone 6
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code. Report failures as findings rather than fixing them.
- No network access (CODE_ONLY network mode).

## Key Decisions Made
- Added new stress test cases to `tests/unit/tools/common/test_patch_explainer.py` to cover:
  - Unhashable addresses in diff changes list.
  - Non-string `pseudo_c` values returned during decompilation.
  - Empty, whitespace, or invalid function names.
  - Empty, whitespace, or null `diff_binaries` data results.
- Verified all 31 unit and stress tests pass with 100% code coverage.
- Formulated final assessment confirming correct exception propagation and prevention of server crashes.
