# BRIEFING — 2026-06-27T02:20:48+09:00

## Mission
Review the unit tests in `tests/unit/tools/analysis/test_capa_tools.py` for correctness, robustness, proper mocking, assertions, and execution.

## 🔒 My Identity
- Archetype: reviewer & critic
- Roles: reviewer, critic
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/reviewer_m2_1/
- Original parent: 7276f128-dc31-45f6-aa95-9c5a0b37b541
- Milestone: Review of CAPA tool unit tests
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code.
- Report failures as findings — do NOT fix them yourself.
- Run tests and verify they pass.
- Write review report in handoff.md.

## Review Scope
- **Files to review**: `tests/unit/tools/analysis/test_capa_tools.py`
- **Interface contracts**: `AGENTS.md`
- **Review criteria**: correctness, style, robust mocking of the capa library, robust assertions, successful unit test execution.

## Review Checklist
- **Items reviewed**: `tests/unit/tools/analysis/test_capa_tools.py`
- **Verdict**: REQUEST_CHANGES
- **Unverified claims**: none

## Attack Surface
- **Hypotheses tested**: exact-match namespace counting vs hierarchical namespace counting
- **Vulnerabilities found**: major logic bug where hierarchical namespaces (used in production CAPA) are not counted towards `high_risk_count` because of exact dictionary lookups.
- **Untested angles**: none

## Key Decisions Made
- Discovered and documented the discrepancy between mocked exact-match namespaces in unit tests and real-world hierarchical CAPA namespaces, masking a bug in the implementation of `run_capa`'s `high_risk_count`.
- Decided to issue a `REQUEST_CHANGES` verdict due to this major testing gap and implementation bug.
