Status: COMPLETED (Review & Adversarial Audit Complete)

- [x] Initial setup and reading mandatory docs (ORIGINAL_REQUEST, PROJECT, worker handoff, challenger handoff).
- [x] Evaluated dynamic synthetic video in `run_shot.py`: `testsrc` replacement verified, empirical inter-frame delta measured at `max_diff = 1.8612 >= 0.8`, critic gate freeze check passed with score 1.00.
- [x] Evaluated async coroutine handling in `antigravity_critic_gate.py`: `_run_coroutine_safely` verified across sync and running event loop contexts, 0 `RuntimeWarning` emitted.
- [x] Verified hygiene and character asset invariants: `04_Assets/characters/` has 62 intact files including 14 core Ep01 portraits; `test_m2_hygiene.py` 6/6 PASS.
- [x] Executed critic gate suite: `test_critic_gate.py` 30/30 PASS.
- [x] Executed tier 1 features suite: `test_tier1_features.py -k "not test_render"` 65/65 PASS.
- [x] Executed challenger 1 and production pipeline regression suites: 10/10 PASS on `test_m3_challenger1_probe.py`, 16/16 PASS on `test_production_pipeline_m3.py`.
- [x] Adversarially probed Scene Gate concat bypass rejection: unapproved scenes (`score < 0.8`, `APPLY_COLOR_MATCH`) return `None`.
- [x] Adversarially probed Thúy Vân resolution in Scene 03: verified `shot03` and `shot05` resolve to Thúy Vân portrait.
- [x] Formulating final handoff report with verdict: APPROVE.
