From 42f64acc274406fae5bbed8ef6021121dbfb8610 Mon Sep 17 00:00:00 2001 From: sylph-decoder Date: Wed, 2 Sep 2026 20:09:04 +0000 Subject: [PATCH] re: pre-register the widened F5 artwork test before reading the capture 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.
