# BRIEFING — 2026-06-27T03:23:00Z

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

## 🔒 My Identity
- Archetype: Teamwork explorer
- Roles: Read-only investigator, analyzer
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/explorer_m7_1_3/
- Original parent: 13d87357-cec0-4f29-9fd1-e0754da4e380
- Milestone: Coverage analysis of assembler.py

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- CODE_ONLY network mode: no external HTTP/HTTPS requests
- Follow handoff protocols and write outputs to explorer_m7_1_3/ folder

## Investigation State
- **Explored paths**:
  - `reversecore_mcp/tools/common/assembler.py` (read & analyzed)
  - `tests/unit/tools/common/test_assembler.py` (read & run via pytest)
- **Key findings**:
  - `assembler.py` coverage is currently at 57% (197 statements, 85 missed).
  - Uncovered areas include fallback import blocks, unsupported/alternative architectures (MIPS, PPC, SPARC, SystemZ, ARM mode v8, Big Endian modes), Capstone warning/error paths, and specific exception handling paths in assembly compilation.
- **Unexplored areas**: None. Complete coverage gap analysis achieved.

## Key Decisions Made
- Use static analysis of target code and test files along with terminal-based coverage reports to pin down every uncovered block.
- Draft concrete test cases and Python test mocks for 100% coverage.
