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.

Crop, Local and Repair were chips at the head of the develop column, sharing a
row with the adjustment groups and told apart from them by the shape of their
highlight. Three things followed from that, and only the last is cosmetic: the
column closes, so the way out of a mode went away with the way in — hence the
duplicate "Done Cropping" over the canvas; the chips are generated from the
operation set, so the widest thing in the sidebar was a row nobody had chosen
the contents of; and a mode and a filter are different kinds of state wearing
one control.
They are a fixed 60px rail down the left now, generated from a single table in
toolrail.slint. A tool is one row of it plus a drawing plus a ViewMode variant;
nothing in app.slint is touched to add one. What is left of the strip is the
group filters, so it is GroupStrip.
The column stops measuring itself. Every panel published a content-width and
declared it as min-width, and the column took the largest — which spent the
photograph's pixels on whatever happened to be widest, and moved the image
sideways when switching tools swapped one set of panels for another. It is
panel-width now, one number in style.yaml.
That number is 360 and it is measured, not picked: the contents report a
minimum of 344 in every mode, and they do not compress below it because a Text
that does not elide reports the same minimum as preferred. 320 was tried and
sliced Paste down the middle. The Flickable's viewport is floored at the
layout's minimum rather than its preferred width for the same reason — content
that is never told how much room it has cannot adapt to having less.
Removing the eight content-width declarations repairs three comments an
earlier edit had spliced sentences into. The raw histogram's note on keeping
its hint short is rewritten rather than dropped: an over-long hint no longer
widens the column, it pushes the column's minimum past the width it has and
clips the panel, which makes that constraint sharper rather than obsolete.

FR-CULL-3's focus peaking. One compute dispatch measures local contrast
in WGSL and writes an overlay texture; on desktop it reaches Slint
through the same zero-copy wgpu import the canvas uses, so nothing
per-pixel touches the CPU on the frame path.
With peaking off the cost is zero and structurally so: focus_overlay
opens with `let settings = self.peaking?;` before the frame is touched,
and clearing drops both overlay textures, so no VRAM is held either.
NFR-P14 is met by construction rather than by measurement -- one
dispatch, no second render, no pipeline compile after session open, and
a test asserting allocations stay at 2 over eight frames. The budget
test asserts 50ms at 4K rather than a tight bound, deliberately: a tight
bound fails on a loaded machine and gets deleted, which is worse than a
loose one that still catches the regression that matters.
TD-1 is amended rather than joined by a TD-6: on Android the overlay
rides the readback that already exists there, roughly doubling that
transfer while peaking is on, and TD-1's own "Done when" removes both
because both are the same missing capability.
Verified: cargo fmt clean; clippy --workspace --all-targets -D warnings
green, which also compiles peaking.slint through dr-ui's build.rs; 11
focus GPU tests and 79 baseline dr-gpu tests pass; 511 dr-ui tests pass.
Not verified: the cfg(target_os = "android") arm, which the host-target
clippy never compiled.
