# Explorer Task: Milestone 6 (patch_explainer.py coverage) Explorer 2

## Goal
Analyze edge cases, exception paths, and heuristics in `reversecore_mcp/tools/common/patch_explainer.py` to design comprehensive tests.

## Context & Inputs
- Target source file: `reversecore_mcp/tools/common/patch_explainer.py`
- Test file: `tests/unit/tools/common/test_patch_explainer.py`

## Instructions
1. Identify all branches and logic splits within `patch_explainer.py`.
2. Detail exactly how to mock `diff_binaries` and `r2_decompile` to reach untested branches.
3. Design specific assertions for the heuristics inside `_generate_explanation` (e.g. gets -> fgets, sprintf -> snprintf, integer overflow MAX logic, logic removal).
4. Document findings and proposed test code in `analysis.md` and `handoff.md` inside your working directory `.agents/explorer_m6_2/`.
