On real sessions the button showed up two or three turns from the bottom, over a screen and a half of transcript that had barely painted anything. The budget now spends paint weight, which is what the DOM actually mounts, and 600 units of it — 10-20 agentic turns measured, where a tool-heavy turn prices at 30-90 and a plain exchange at 5-10. A floor of 8 turns covers the session of enormous turns that a weight-only cut still truncates hard; it applies to a real page only, so the small first-paint commit stays small and the backfill a frame later fills the rest. Measured on four stored sessions at the same budget: one went from 3 turns visible to 12, another from 3 to 4, two unchanged. The store window still caps what the DOM can reach at all.
