# Progress — Challenger 1 (Milestone M3 Iteration 2 Gate Verification)

Last visited: 2026-10-09T07:06:00Z

## Status
Empirical probing and stress-testing complete. Formulating REQUEST_CHANGES verdict due to latent cross-character tail frame chaining defect in `classify_shot_take` and unapplied `gemini_banana_prompts.json` updates.

## Steps
- [x] Received dispatch and recorded in DISPATCH.md
- [x] Initialized BRIEFING.md and progress.md
- [x] Read ORIGINAL_REQUEST.md
- [x] Read orchestrator_1/PROJECT.md
- [x] Read worker_m3_remediation_2/handoff.md
- [x] Read challenger_m3_1/handoff.md for historical context
- [x] Execute `pytest tests/test_m3_challenger1_probe.py -v` (10/10 PASS, un-xfailed)
- [x] Execute Cross-Character Safeguard Probe across all 140 shots of Scenes 01 to 10 (Static resolution: 0 leaks)
- [x] Execute `pytest tests/test_production_pipeline_m3.py -v` (16/16 PASS)
- [x] Execute full regression test suites (168 tests total across all suites pass)
- [x] Stress-test dynamic shot transitions: DISCOVERED LATENT DEFECT in `classify_shot_take` and `gemini_banana_prompts.json` causing actor switch shots to be classified as `CONTINUOUS_TAKE` and chaining cross-character tail frames
- [ ] Synthesize findings into handoff.md and send verdict to parent orchestrator
