RUST.md gains the pass's findings with their commits and the numbers: the block model held under a per-character prefix property, the size-independent hit-box defect and its fix, the tail-rebuild selection gap, why the three new debug_asserts are whole-set, the text-shape counter that turns "a delta costs one block" into a measurement, and the verification bench run. IRIS_TODO.md's "the bar's own grey background is not drawn" is withdrawn: decoding the screencap puts it at rgb(41,40,49), full width, y2245..y2365 -- drawn, and dark on black, which is most likely what the earlier reading was.
