 - P17: the editor keeps every owner offset on whole characters of its text (checked on intake, carried through edits by `editor::anchors`, cleared when the whole text changes); stale selections and edit batches are dropped; a painted row whose line the text lost takes no click, drag or IME query; the sticky header reads this frame; a glob too big to compile matches nothing; a missing font advance logs. Kept: owner contracts and construction. Review: 5 rounds, passed on the fifth.
 - P18: row paints and the font advance log gpui faults; a pty side caps at what ConPTY and alacritty's pixel sizes hold; a default shell past the list keeps the one before. Kept: constant regexes, captured matches, keyed rows, non-empty shells. Review: 2 rounds.
