# BRIEFING — 2026-06-27T12:18:37Z

## Mission
Analyze test coverage gaps for reversecore_mcp/tools/common/assembler.py and recommend a strategy/test cases for 100% coverage.

- Milestone: m7_1_2

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Analyze test coverage gaps for reversecore_mcp/tools/common/assembler.py. Identify lines/branches not covered. Recommend strategy/test cases. Do not implement changes or write to source code directly.

## Investigation State
- **Explored paths**: `reversecore_mcp/tools/common/assembler.py`, `tests/unit/tools/common/test_assembler.py`
- **Key findings**: Identified all 81 missing statements/branches (e.g. module imports reload, parameter mapping for non-x86 architectures, Keystone execution exceptions, Capstone warning blocks). Created a comprehensive testing strategy.
- **Unexplored areas**: None.

## Key Decisions Made
- Chose to use `importlib.reload` with mocked `sys.modules` to cover module import-time `ImportError` exceptions.
- Formulated parameterized tests for `get_keystone_params` and `get_capstone_params` to test all architecture-mode pairs.
