# BRIEFING — 2026-10-01T02:24:00Z

## Mission
Investigate failure of `python tools/lint/check_code_and_doc_hygiene.py --strict`, focusing on `.agents` scanning and rogue files in `.agents/teamwork/`.

## 🔒 My Identity
- Archetype: explorer
- Roles: investigation, synthesis
- Working directory: c:\Projects\FreeExile\.agents\teamwork\explorer_orch7_1
- Original parent: d9c449d5-0493-487f-993e-5eb085ae9740
- Milestone: Investigation of hygiene audit failure and `.agents` exclusion

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Write only to .agents/teamwork/explorer_orch7_1/
- No source code or tests in .agents/teamwork/
- Never name a file AGENTS.md or GEMINI.md

## Investigation State
- **Explored paths**:
  - `tools/lint/check_code_and_doc_hygiene.py` (lines 1-373)
  - `.agents/teamwork/reviewer_m1_2/adversarial_tests.py` (594 lines)
  - `.agents/teamwork/reviewer_m1_2/handoff.md`
  - `.agents/teamwork/orchestrator_6/GATE_STATUS.md`
  - `.agents/teamwork/ORIGINAL_REQUEST.md` (`## 2026-10-01T00:46:52Z`)
  - `tests/security_fuzzing/test_chat_concurrency_and_routing_adversarial.py`
  - `tests/security_fuzzing/test_chat_moderation_adversarial.py`
  - Inventory of all 553 files in `.agents/teamwork/`
- **Key findings**:
  - `check_code_and_doc_hygiene.py` scans root recursively; without `.agents` in `EXCLUDE_DIRS`, it traverses 539 agent files (total scanned 1053 vs 514).
  - In git commit `3be7f31`, `EXCLUDE_DIRS` had `.antigravity`, `.git`, `.venv`, etc., but omitted `.agents`.
  - `.agents/teamwork/reviewer_m1_2/adversarial_tests.py` (594 lines) exceeded `CODE_HARD_CAP` (500 lines), causing `check_code_and_doc_hygiene.py --strict` to fail with exit code 1.
  - The working directory currently contains an unstaged edit in `tools/lint/check_code_and_doc_hygiene.py` adding `".agents"` to `EXCLUDE_DIRS` (mtime 2026-10-01 09:15:50), making current runs return exit code 0.
  - 46 non-metadata code/test files exist across `.agents/teamwork/`, including proposed replacement files, agent scratch scripts, and 4 `__pycache__` directories.
  - All 14 tests in `adversarial_tests.py` pass (0.34s) and provide unique coverage for chat policies and 64-shard routing.
- **Unexplored areas**: None. Problem space and fix strategy fully mapped.

## Key Decisions Made
- Confirmed root cause as dual vulnerability: missing `.agents` in `EXCLUDE_DIRS` combined with layout convention breach (594-line test file in subagent workspace).
- Formulated definitive two-pronged fix strategy:
  1. Commit `".agents"` in `EXCLUDE_DIRS` of `tools/lint/check_code_and_doc_hygiene.py`.
  2. Clean up rogue `.agents/teamwork/` test/code files, migrating valuable tests to `tests/security_fuzzing/` after modular splitting (< 500 lines).
