NFR-A11Y-3 — no status conveyed by hue alone — read as untagged, and
outstanding.md said "no compliance work found". Both were wrong. Five places
already implement it, and four of them name the requirement in a comment
explaining the design; what none of them had was a TRACES line.
- `histogram.rs::percentage` states clipping as a figure and keeps `<0.1%`
distinct from `0%`, so the text cannot say "none" while the marker beside it
is lit.
- `histogram.slint`'s ClipReadout is the other half: a marker that appears and
disappears rather than changing tint, and the figure next to it. Either alone
reads.
- `library.slint`'s star strip is a solid star against an outline, differing in
shape and luminance, over an achromatic palette.
- `library.slint`'s FlagMark is a tick against a cross, and a reject also dims
its whole cell.
- `peaking.slint`'s colour chips say "Red" and "Cyan". A control for choosing
between hues, presented only as hues, is unusable by exactly the person most
likely to need it.
The tag is honest about being wider than the evidence, and outstanding.md now
records both gaps. Only the clipping clause has a test that would fail if the
behaviour were removed; the three Slint components are argued rather than
asserted. And the requirement's first named example — catalog colour labels —
has no interface at all: `label` is a nullable column nothing writes or shows.
That clause is untestable rather than satisfied, and closes when the label UI
is built with a shape from the start.
