Ten-second shot through a fence with a large foreground arm and shoulder; the runner crosses, stops, swings and exits at frame edge, consistent identity throughout.

Task: One take through a chain-link fence: a runner crosses a lawn, a foreground figure's raised arm dominates frame right, the runner reacts and exits.

Outcome: succeeded

0.63 s: Runner in grey tee crosses the lawn left to right behind the fence wire; brick building behind.
1.88 s: A large raised arm and shoulder of a figure in a black tank top enters frame right and stays in the foreground.
3.14 s: Runner has stopped and stands square to camera; fence mesh crosses the frame.
5.65 s: Face details change slightly (glasses-like shapes at this size); uncertain at 320 px.
6.90 s: Runner swings an arm toward the foreground figure.
8.16 s: Runner turns away and bends; the foreground arm has left frame.
9.41 s: Runner exits at the left screen edge; hedge and tree remain.

Intent vs result: The peg video (9.0 s vs 10.04 s output) shows a grey runner at the left crossing the lawn and a large grey foreground mass on the right from about 2 s; the output keeps that geography and replaces the mass with a person's arm and shoulder, retimed slightly longer.

Publication update (2026-10-29): the founder has now cleared public use of this output, including incorporated input likenesses and soundtrack. Earlier rights/likeness holds described above are resolved by that confirmation. Reference-input files remain private. Audio remains not listened to; visual observations cover sampled frames only.

Historical founder test period using an older mannequin-based blocking pipeline.

Evidence claims:
- [sourced_fact] Timestamped observations above come from viewing 8 sampled frames of the output (sampled visual inspection, not full playback).
- [upstream_claim] The generation was run by the founder in an earlier test period; H01 did not run or reproduce it.
- [inference] Foreground occluders defined in the peg video survive as real people; lawn, fence and exit direction track the pre-visualisation.
