# BRIEFING — 2026-06-26T22:22:15Z

## Mission
Audit integrity and test coverage of reversecore_mcp/tools/common/memory_tools.py to detect any integrity violations, hardcoding, or bypasses.

## 🔒 My Identity
- Archetype: forensic_auditor
- Roles: [critic, specialist, auditor]
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/auditor_m5_1/
- Original parent: 0c44a811-b4db-47e1-891b-60482d466a84
- Target: Milestone 5 (memory_tools.py coverage)

## 🔒 Key Constraints
- Audit-only — do NOT modify implementation code
- Trust NOTHING — verify everything independently
- CODE_ONLY network mode — no external network access
- Run every check from the Integrity Forensics section

## Current Parent

## Audit Scope
- **Work product**: `reversecore_mcp/tools/common/memory_tools.py` and `tests/unit/tools/common/test_memory_tools.py`
- **Profile loaded**: General Project (Development Mode)
- **Audit type**: forensic integrity check

## Audit Progress
- **Phase**: reporting
- **Checks completed**:
  - Phase 1: Source code analysis (hardcoded output detection, facade detection, pre-populated artifact detection) - PASS
  - Phase 2: Behavioral verification (build and test execution, output verification, dependency check) - PASS
  - Phase 3: Adversarial stress testing (edge cases, boundary limits, assumptions check) - PASS
- **Findings so far**: CLEAN. The implementation is authentic, matches constraints, achieves 100% target coverage, and passes all tests.

## Key Decisions Made
- Checked all source files (`memory_tools.py` and `core/memory.py`).
- Ran all unit and core tests, verifying 100% coverage on memory tools and 87.33% total repository coverage.
- Prepared Adversarial Challenge analysis.

## Attack Surface
- **Hypotheses tested**:
  - FTS5 syntax errors trigger fallback: Confirmed fallback to SQL LIKE search handles FTS5 syntax exceptions.
  - Large binary hashing: Whole-file read could cause OOM.
  - SQLite concurrent writes: Locked database errors under load.
- **Vulnerabilities found**: No logical vulnerability in unit tests, but potential production scaling limitations on large binaries or highly concurrent DB access.
- **Untested angles**: None.

## Loaded Skills
- None loaded.
