Rating and flagging in develop (FR-UI-5, amended 2026-09-19) landed with
the keyboard audit: 0-5, P, X and U in develop's key scope, stars and
Pick/Reject in its top bar, and flag and stars on the roll's cells. Two
of the amendment's rules were held by nothing. The keys must judge the
photograph on screen and never a selection left behind in the grid, and
judging must not move on to the next frame, which is culling's
auto-advance and not develop's.
The rating, flag and label callbacks that take a row each spelled the
row-to-image lookup themselves. It is now one function, `image_at_row`,
which answers None for a negative row as well as one past the end: the
roll passes -1 when the open photograph is outside the loaded window,
and the right answer then is to judge nothing. A test says so. The key
bindings live in Slint, where no test can press them, so a second test
reads develop's handler as the gestures gate and the canvas-order test
do, and checks that each judgement key calls the row callback on
`library-roll-current` and that none of them steps the roll or the
cursor.
The writes themselves go through `apply_judgement`, the grid's own path:
one catalog statement, then the sidecar and XMP writes behind it.
