# EMPIRICAL CHALLENGE REPORT: MILESTONE M2 ITERATION 2 GATE VERIFICATION > **Agent**: Challenger 1 (`challenger_m2_iter2_1`) > **Roles**: critic, specialist > **Parent Orchestrator**: `97faf5e5-a830-491c-b78c-2af12175badf` > **Working Directory**: `c:\Projects\KieuStory\.agents\teamwork\challenger_m2_iter2_1` > **Milestone**: Milestone M2 - Archival & Workspace Hygiene (Iteration 2 Gate Verification) > **Timestamp**: 2026-10-09T03:37:30Z > **Handoff Type**: Hard > **CHALLENGE VERDICT**: **REQUEST_CHANGES** --- ## 1. OBSERVATION I independently executed all verification commands, direct filesystem probes, PIL decoding harnesses, and test runners on the live workspace. Here are the exact verbatim observations: ### 1.1. Rogue Process Termination Check (PIDs 41044 / 65208) - **Execution Command**: ```python import psutil, os print("41044 exists:", psutil.pid_exists(41044)) print("65208 exists:", psutil.pid_exists(65208)) ``` - **Verbatim Result**: ``` Checking PIDs 41044 and 65208: 41044 exists: False 65208 exists: False ``` - **Rogue Process Scan**: Iterating over all running processes with `psutil.process_iter(['pid', 'name', 'cmdline'])` revealed zero background processes executing `production_orchestrator.py`, `run_shot.py`, or `multi_worker_orchestrator.py`. The only python processes active are system bridges (`mem0_service.py`, `mcp_server_git`, `smart_sqlite.py`, `markitdown_mcp.py`, `uvicorn`). - **Status**: PASSED. PIDs 41044 and 65208 are confirmed terminated. --- ### 1.2. Keyframe Directory Purge Verification (`04_Assets/keyframes/`) - **Execution Command**: ```python import os ep01_dirs = [d for d in os.listdir("04_Assets/keyframes") if d.lower().startswith("ep01")] root_ep01_file = os.path.exists("04_Assets/keyframes/ep01_scene03_start_720p.png") print("Ep01 keyframe dirs:", ep01_dirs) print("Root ep01 keyframe exists:", root_ep01_file) ``` - **Verbatim Result**: ``` Ep01 keyframe dirs: [] Root ep01 keyframe exists: False ``` - **Non-Ep01 Keyframe Invariants**: - Non-Ep01 keyframe directories: Exactly 67 directories intact. - Non-Ep01 keyframe root files: Exactly 10 files intact. - **Status**: PASSED. 0 Ep01 keyframe directories and files exist in `04_Assets/keyframes/`. --- ### 1.3. Character Portrait Integrity & PIL Pixel Decoding (`04_Assets/characters/`) - **Execution Command**: Evaluated all 14 core character portraits with PIL `img.verify()` and `img.load()` (full pixel buffer decoding): ```python from PIL import Image from pathlib import Path root = Path('04_Assets/characters') core = [ ('01_Main_Protagonists/thuy_kieu_maiden_16yo_720p.png', (1280, 720)), ('01_Main_Protagonists/thuy_kieu_maiden_16yo_master.png', (1376, 768)), ('01_Main_Protagonists/thuy_van_maiden_16yo_720p.png', (1280, 720)), ('01_Main_Protagonists/thuy_van_maiden_16yo_master.png', (1376, 768)), ('01_Main_Protagonists/kim_trong_18yo_720p.png', (1280, 720)), ('01_Main_Protagonists/kim_trong_18yo_master.png', (1376, 768)), ('02_Vuong_Family_And_Fate/vuong_quan_16yo_720p.png', (1280, 720)), ('02_Vuong_Family_And_Fate/vuong_quan_16yo_master.png', (1376, 768)), ('02_Vuong_Family_And_Fate/vuong_ong_55yo_720p.png', (1280, 720)), ('02_Vuong_Family_And_Fate/vuong_ong_55yo_master.png', (1376, 768)), ('02_Vuong_Family_And_Fate/vuong_ba_50yo_720p.png', (1280, 720)), ('02_Vuong_Family_And_Fate/vuong_ba_50yo_master.png', (1376, 768)), ('02_Vuong_Family_And_Fate/dam_tien_720p.png', (1280, 720)), ('02_Vuong_Family_And_Fate/dam_tien_master.png', (1376, 768)) ] ``` - **Verbatim Result**: ``` Testing 14 core character portraits: OK: 01_Main_Protagonists/thuy_kieu_maiden_16yo_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 01_Main_Protagonists/thuy_kieu_maiden_16yo_master.png -> size=(1376, 768), mode=RGB, format=PNG OK: 01_Main_Protagonists/thuy_van_maiden_16yo_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 01_Main_Protagonists/thuy_van_maiden_16yo_master.png -> size=(1376, 768), mode=RGB, format=PNG OK: 01_Main_Protagonists/kim_trong_18yo_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 01_Main_Protagonists/kim_trong_18yo_master.png -> size=(1376, 768), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/vuong_quan_16yo_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/vuong_quan_16yo_master.png -> size=(1376, 768), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/vuong_ong_55yo_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/vuong_ong_55yo_master.png -> size=(1376, 768), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/vuong_ba_50yo_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/vuong_ba_50yo_master.png -> size=(1376, 768), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/dam_tien_720p.png -> size=(1280, 720), mode=RGB, format=PNG OK: 02_Vuong_Family_And_Fate/dam_tien_master.png -> size=(1376, 768), mode=RGB, format=PNG Testing all 62 character files for PIL decodability: Total character files found: 62 All character files successfully verified and decoded without corruption! ``` - **Status**: PASSED. All 14 core portraits and all 62 character assets are 100% valid, uncorrupted, and conformant. --- ### 1.4. Legacy Archive Verification (`04_Assets/archive/ep01_legacy_v1/`) - Exactly 184 `.mp4` files present directly in `04_Assets/archive/ep01_legacy_v1/`. - Total size: 2,249,030,734 bytes (2.095 GB > 2.0 GB). - Binary probing: 184 / 184 files contain valid `ftyp` box in their first 32 bytes. - `04_Assets/archive/ep01_legacy_v1/README.md`: 9,931 bytes, fully documented with Vietnamese IP citations (Articles 4(8), 14, 20, 43 of Law on Intellectual Property), creator identification (Nguyễn Sĩ Sơn, CCCD 031090010018), and creative defense. - `04_Assets/archive/ep01_legacy_v1/exports/`: 17 legacy scene masters preserved. - **Status**: PASSED. --- ### 1.5. Workspace Hygiene Test Suite Failure & Premature Video Discovery - **Execution Command**: ```powershell python -m pytest tests/test_m2_hygiene.py -v ``` - **Exit Code**: 1 (FAILURE) - **Verbatim Error**: ``` ============================= test session starts ============================= platform win32 -- Python 3.11.9, pytest-9.1.1, pluggy-1.6.0 -- C:\Users\Admin\AppData\Local\Programs\Python\Python311\python.exe cachedir: .pytest_cache rootdir: C:\Projects\KieuStory plugins: anyio-4.15.1, platformdirs-4.12.4, asyncio-1.4.0 asyncio: mode=Mode.STRICT, debug=False, asyncio_default_fixture_loop_scope=None, asyncio_default_test_loop_scope=function collecting ... collected 6 items tests/test_m2_hygiene.py::test_archive_ep01_video_count PASSED [ 16%] tests/test_m2_hygiene.py::test_videos_ep01_purged FAILED [ 33%] tests/test_m2_hygiene.py::test_keyframes_ep01_purged PASSED [ 50%] tests/test_m2_hygiene.py::test_archive_readme_legal_documentation PASSED [ 66%] tests/test_m2_hygiene.py::test_character_portraits_unharmed PASSED [ 83%] tests/test_m2_hygiene.py::test_non_ep01_assets_unharmed PASSED [100%] ================================== FAILURES =================================== ___________________________ test_videos_ep01_purged ___________________________ def test_videos_ep01_purged(): """Assert 0 files with 'ep01' remain in 04_Assets/videos/.""" assert VIDEOS_DIR.exists(), f"Videos directory does not exist: {VIDEOS_DIR}" ep01_remaining = [f for f in os.listdir(VIDEOS_DIR) if "ep01" in f.lower()] > assert len(ep01_remaining) == 0, ( f"Expected 0 Ep01 files remaining in {VIDEOS_DIR}, but found {len(ep01_remaining)}: {ep01_remaining}" ) E AssertionError: Expected 0 Ep01 files remaining in C:\Projects\KieuStory\04_Assets\videos, but found 1: ['ep01_scene01_shot01_10s_v1.mp4'] E assert 1 == 0 E + where 1 = len(['ep01_scene01_shot01_10s_v1.mp4']) tests\test_m2_hygiene.py:69: AssertionError =========================== short test summary info =========================== FAILED tests/test_m2_hygiene.py::test_videos_ep01_purged - AssertionError: Ex... ========================= 1 failed, 5 passed in 0.30s ========================= ``` ### 1.6. Forensic Root Cause of Failure - **File Detected**: `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4` - File size: 357,801 bytes. - Creation timestamp: `2026-10-09 10:32:41.065001` (+07:00). - **Origin**: At `10:32:13` (+07:00), script `scratch/download_shot01_blob.py` was created and executed. Lines 44-46 of `scratch/download_shot01_blob.py`: ```python raw_bytes = base64.b64decode(b64_data) out_path = Path('04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4') out_path.parent.mkdir(parents=True, exist_ok=True) out_path.write_bytes(raw_bytes) ``` This script actively downloaded a video from Muse.ai thread and wrote it into `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4`. - **Impact**: The presence of this premature/experimental video file violates the clean-slate condition for Milestone M2 and causes `test_m2_hygiene.py::test_videos_ep01_purged` to fail. --- ## 2. LOGIC CHAIN 1. **Gate Condition 2**: - The milestone directive states: *"Empirically verify that 0 Ep01 video files exist in 04_Assets/videos/ and 0 Ep01 keyframe directories exist in 04_Assets/keyframes/."* - Observation 1.5 and 1.6 confirm that `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4` currently exists on disk. - Therefore, Gate Condition 2 is violated (`len(ep01_videos) == 1 != 0`). 2. **Gate Condition 4**: - The milestone directive states: *"Run python -m pytest tests/test_m2_hygiene.py -v"*. - Observation 1.5 confirms that running this command produces Exit Code 1 with `AssertionError: Expected 0 Ep01 files remaining in C:\Projects\KieuStory\04_Assets\videos, but found 1: ['ep01_scene01_shot01_10s_v1.mp4']`. - Therefore, Gate Condition 4 has failed. 3. **Inadmissibility of Premature Production Artifacts**: - Milestone M2's objective is to establish an authentic, pristine clean slate prior to Milestone M3 production. - Any video generated or downloaded ahead of the formal M3 batch pipeline contaminates the workspace baseline and breaks reproducible gate verification. 4. **Empirical Challenger Mandate**: - Under the Empirical Challenger contract: *"If you cannot reproduce a bug empirically, it does not count. Run verification code yourself. Do NOT trust the worker's claims or logs."* - Because the test failure is 100% reproducible on the physical disk, the gate verdict must be `REQUEST_CHANGES`. --- ## 3. CAVEATS - **No Caveats on Verification Scope**: All PIDs, video directories, keyframe directories, character files, archive files, and test suites were tested directly on the live Windows filesystem with zero mocks. - **Timing Context**: Peer reviewers and the auditor completed their checks prior to `10:32:41` (+07:00), which explains why earlier checks observed 0 video files. The appearance of `ep01_scene01_shot01_10s_v1.mp4` at `10:32:41` demonstrates why active continuous testing is vital. --- ## 4. CONCLUSION & VERDICT **VERDICT**: **REQUEST_CHANGES** Milestone M2 cannot pass gate verification in its current state because: 1. `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4` is present in `04_Assets/videos/`. 2. `python -m pytest tests/test_m2_hygiene.py -v` fails on `test_videos_ep01_purged`. ### Required Remediation Actions: 1. Remove `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4` from `04_Assets/videos/` (or move it to `scratch/` or an appropriate test directory). 2. Ensure no interactive or scratch scripts (such as `scratch/download_shot01_blob.py`) write premature files into production `04_Assets/videos/` outside the formal M3 production pipeline. 3. Re-run `python -m pytest tests/test_m2_hygiene.py -v` to achieve 6/6 PASS before issuing M2 approval. --- ## 5. VERIFICATION METHOD To independently verify this finding: 1. **Check Presence of Contaminating File**: ```powershell python -c "import os; print([f for f in os.listdir('04_Assets/videos') if 'ep01' in f.lower()])" ``` *Current output*: `['ep01_scene01_shot01_10s_v1.mp4']` (Expected clean slate: `[]`). 2. **Run Authoritative Test Suite**: ```powershell python -m pytest tests/test_m2_hygiene.py -v ``` *Current output*: Fails at `test_videos_ep01_purged` with `AssertionError: assert 1 == 0`. 3. **Verify Remediation**: Once `04_Assets/videos/ep01_scene01_shot01_10s_v1.mp4` is removed, re-running `python -m pytest tests/test_m2_hygiene.py -v` will produce `6 passed in <0.3s`, Exit Code 0.
