# Progress Tracker - Challenger 2 (M1 Iteration 3 Gate Verification)

- Last visited: 2026-10-09T05:36:00Z
- Status: Live empirical probes and test suites completed. Drafting handoff report and final verdict.

## Steps
- [x] Step 1: Initialize DISPATCH.md, BRIEFING.md, progress.md
- [x] Step 2: Read ORIGINAL_REQUEST.md, PROJECT.md, and worker_m1_remediation_3/handoff.md
- [x] Step 3: Empirically verify surgical safeguards with live Python probes:
  - [x] Probe Thúy Vân with adversarial Thúy Kiều reference_start_frame -> resolved strictly to thuy_van_maiden_16yo_720p.png
  - [x] Probe compound anchor ep01_scene10_shot07 with adversarial Thúy Kiều reference -> resolved strictly to kim_trong_18yo_720p.png
  - [x] Probe attendant ep01_scene06_shot05 -> resolved strictly to tieu_dong_kim_trong_720p.png (not Kim Trọng)
- [x] Step 4: Run test suites:
  - [x] python -m pytest tests/test_critic_gate.py -v (30 passed)
  - [x] python -m pytest tests/test_m1_challenger2_probe.py -v (41 passed)
  - [x] python -m pytest tests/test_adversarial_deep_probe.py -v (13 passed)
  - [x] python -m pytest tests/test_challenger1_empirical_stress.py -v (15 passed)
  - [x] pytest tests/test_tier1_features.py -k "not test_render" -v (65 passed)
  - [x] python -m pytest tests/test_m2_hygiene.py -v (6 passed)
- [x] Step 5: Conduct additional adversarial stress testing:
  - [x] Uppercase / backslash path tampering resilience
  - [x] Full 192-shot Ep01 audit: 0 cross-contamination anomalies, 0 keyframe tail leakage on Cinematic Cuts
  - [x] Substring shadowing check across attendants (tiểu đồng, quản gia) vs Kim Trọng
- [ ] Step 6: Write handoff.md with challenge verdict (APPROVE)
- [ ] Step 7: Update BRIEFING.md and notify orchestrator
