F5's artwork half rests on 5 frames. This run presses A at the sweep's gate instead of 40 frames later, giving ~40 frames of still-animating artwork, and states the prediction for both outcomes before the log is opened.

Pre-registration — widening F5's 5-frame artwork window
Committed before the capture is read. F5 concluded Ⓐ forces the plate and
leaves the artwork's timeline alone, but the artwork half rested on 5 frames
(446–450 in f5): the only stretch where the press had landed and something was
still animating. Everything else was at α255 and could not discriminate.
This run presses Ⓐ at the sweep's gate instead — PRESS2_FRAMES=3 rather
than 40 — so the press lands at title t≈70 with ~40 frames of artwork
animation still ahead of it, an 8× wider window.
The prediction
Comparing f5-early against the no-press control f6b, aligned by the sweep's
position, over the four quads that are still ramping:
8ECA:-1.00, 8ECA:-0.90, EAC3:-0.82, 8154:-0.74.
| if Ⓐ … | those four |
|---|---|
| only forces the plate (F5's claim) | continue identically to the control for the full ~40 frames |
| advances a shared clock | terminate early, jump, or change step |
A pass is the boring outcome and I have said so first. The failure mode this guards against is that F5's artwork claim was read off a window too short to show a divergence that a longer one would reveal.
What it still will not cover
The plate's identity, the 1.7× clock conflict, and whether Ⓐ drives some third clock — a cut is consistent with several mechanisms.
