Scroll::content_len was 0.0 both for 'nothing here' and for 'not drawn yet', so the first frame's clamp found a scroll range of zero, read amt == len as 'sitting at the end' and set snap_end -- and the next frame, now knowing the real length, jumped to it. On a phone that put a code fence at the end of its longest line, mid-word, before anybody touched it. It is an Option now, and the clamp does not answer a question it cannot yet answer. Which edge an area opens at is also a caller's decision rather than a default: scrollable_on starts at the beginning (what is read), scrollable_to_end pins to the end while content grows (what is typed -- the composer), both through one Scroll::new(inner, axis, at_end). And tool.rs's raw_block pans sideways again: the 2026-09-06 'a scrollable_on(Axis::X) around a non-editable Text draws nothing' defect does not reproduce, most likely fixed by the shaped-mask work, so a long command is readable rather than clipped.
