# BRIEFING — 2026-10-09T03:17:30Z

## Mission
Investigate previous M2 integrity violations (residual keyframes, rogue PID 41044 process, attestation discrepancy) and formulate a deterministic remediation plan for Worker 2.

## 🔒 My Identity
- Archetype: explorer
- Roles: investigation, synthesis
- Working directory: c:\Projects\KieuStory\.agents\teamwork\explorer_m2_remediation_1
- Original parent: 97faf5e5-a830-491c-b78c-2af12175badf
- Milestone: M2 Remediation (Archival & Workspace Hygiene)

## 🔒 Key Constraints
- Read-only investigation — do NOT implement fixes directly in source code/workspace (reports & plans in explorer folder only)
- Complete audit of all mandatory evidence files without omission
- Deterministic actionable strategy for Worker 2

## Investigation State
- **Explored paths**:
  - `ORIGINAL_REQUEST.md`, `orchestrator_1/PROJECT.md`
  - `auditor_m2_1/handoff.md`, `reviewer_m2_1/handoff.md`, `reviewer_m2_2/handoff.md`, `challenger_m2_1/handoff.md`, `challenger_m2_2/handoff.md`
  - `worker_m2_hygiene_1/handoff.md`, `DISPATCH.md`, `BRIEFING.md`
  - `04_Assets/archive/ep01_legacy_v1/`, `04_Assets/videos/`, `04_Assets/keyframes/`, `04_Assets/characters/`
  - `05_Production_Pipeline/production_orchestrator.py`, `run_shot.py`, `muse_invpw_driver.py`, `episode_manager.py`
  - `tests/test_m2_hygiene.py`, `tests/test_tier1_features.py`
  - Running system processes (PID 41044, PID 65208)
- **Key findings**:
  - PID 41044 (child of PID 65208) was launched at 10:01:36 AM and is actively running `production_orchestrator.py --batch-scene ep01_scene01`, generating premature files in `videos/` and `keyframes/`.
  - Directory `ep01_scene10_shot14` was created on disk at 09:53:40 AM and left empty, causing `test_keyframes_ep01_purged` to fail.
  - Attestation discrepancy confirmed: Worker 1 tested at 09:52:50 AM, but `ep01_scene10_shot14` was created at 09:53:40 AM and Worker 1 did not re-test before submitting handoff at 09:54:48 AM.
  - Pipeline eager directory creation vulnerability located in `run_shot.py:295` and `muse_invpw_driver.py:88` where `mkdir` is executed before confirming frame extraction.
  - Invariant baseline is 100% intact: 184 archived videos (2.25 GB), 62 character files, 118 non-Ep01 videos, 67 non-Ep01 keyframe dirs, 10 keyframe root files.
- **Unexplored areas**: None for M2.

## Key Decisions Made
- Formulated an exact, deterministic 5-step remediation strategy for Worker 2 covering process termination, asset purging, pipeline hardening, test execution, and verbatim attestation.
- Documented findings in `analysis.md` and complete handoff report in `handoff.md`.
