Black-and-white silent-film pastiche: two readable intertitle cards, a flour-cloud gag and a dog, closing on an iris to black; background shopfront text is garbled.

Task: Silent-film market chase in ten pieces: eight photographed shots and two intertitle cards, with a cart, a ladder, a barrow, a constable and a terrier.

Outcome: succeeded

0.63 s: Intertitle card reads 'THE PIE PINCHER STRIKES AT NOON.' in period lettering.
1.88 s: Iris-in on a man in a bowler beside a flour barrow.
4.39 s: Close on a bearded constable; shop sign behind is garbled text.
8.15 s: Flour bursts from a bag at the cart; a figure on the ladder.
9.40 s: Frame filled with flour cloud.
10.66 s: Second card reads 'STOP! IN THE NAME OF LUNCHEON!'.
14.42 s: Narrow alley: a man lifts a pie triumphantly.
18.18 s: Terrier eats from a bowl in the alley.
19.44 s: Iris closes on the dog; frame is black by 19.75 s.

Intent vs result: Observed two intertitle cards, matching the requested count; detector counts six cuts at threshold 0.30, fewer than the ten pieces requested because dissolves and cloud wipes are soft. The black tail (19.75-20.0 s) is an iris closing, not a failure.

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.

Evidence claims:
- [sourced_fact] Timestamped observations above come from viewing 19 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] Readable period intertitles and a coherent gag structure came from text alone; shopfront and background signage still came out as garbled glyphs, so keep legible text only in the intertitle cards.
