IRIS_TODO's 2026-09-07 top-edge entry closed with the root cause of each, the six layer-1 test names, and what was suspected and turned out not to be it -- no culling test compared a row's top against the viewport's, and 03c6be8's header duplicate is untouched and still open. The later report's "you shouldn't be able to scroll below the bottom (or above top)" is ticked with why the clamp is a correction measured from the layout walk rather than a clamp inside the scroll setter: nothing at the moment of a scroll knows where the content ends. RUST.md gains the same account in "Where things stand", plus the three things this said about the new test rig -- layer 1 found all of it in seconds and the emulator was not used; layer 2 is where the missing clip is visible, with the command; and an assertion that reads the wrong thing hides the bug it is for, which is how a list resting 1398px past its own first row passed a test about stopping at that row. Also the last of the six tests, the bottom end of the clamp (`scrolling_past_the_last_row_settles_on_it`) -- the same rule at the edge the top-edge work had no reason to touch.
