dtourolleandClaude Opus 5 94a2686dcb Fit the interface to the system bars, the finger and the back key

Four faults that only show on a device, and one that was hiding on the
desktop too.

The system bars. Target SDK 36 forces edge-to-edge, so the window spans
the display and the develop status strip was drawn underneath the clock
and the wifi icons. Slint already computes the inset from Android's
OnApplyWindowInsetsListener and exposes it as Window.safe-area-insets;
nothing read it. The four views now sit inside a shell placed within the
safe area. Every inset is zero on the desktop, so that layout does not
move.

Sliders under a finger. A Flickable steals any gesture that drifts more
than 8 logical pixels along its scrolling axis within half a second of
the press, and it steals it by cancelling the child. ParamSlider's axis
test correctly declined to claim vertical drags, but nothing told the
Flickable to stand down once a drag was claimed — so an adjustment would
start moving and then be taken away mid-motion. A mouse holds a
horizontal line closely enough to stay under 8px; a finger does not,
which is why these worked on the desktop and not on the tablet. The
claim now sets `interactive: false` for the rest of the gesture.

The tone curve had the same fault and worse: its points are dragged
vertically, which is the Flickable's own axis, so every drag was stolen
— on the desktop as well.

The back gesture. Nothing handled it, so back closed the application
from anywhere in it. Android delivers it as Key.Back to the focused item
and bubbles it up the ancestors, which is the second reason the shell
wraps the views rather than sitting beside them. The order is innermost
first: settings, then crop, then zoom, then develop to the grid, then a
collection scope. Answering false at the top of the stack leaves Android
to close the activity, as it does for every other application there.
Escape does the same on a keyboard.

back_step is a pure function over a flat NavState so the ordering can be
tested without a backend: which of two states is left first is the whole
of the feature, and it is the part that is easy to get subtly wrong when
spelled out in nested ifs over live properties.

Develop's canvas now takes focus on show. Without it the arrow keys did
nothing until the canvas was clicked, and Key.Back had no focus item to
bubble from.

Panels that close. The collections sidebar and the develop column are
collapsible from the grid header and the status strip. The layout class
now supplies only the default: a panel closed to see more of a
photograph stays closed while the window keeps its shape, and the choice
is dropped when the class changes, because rotating a tablet asks a
different question from the one answered in landscape. IMAGE became a
Section, being the only group in the column that could not be put away
and the one whose content is read first and needed least.

Pinch to zoom on the develop canvas, anchored on the midpoint between
the fingers (FR-UI-4). The wheel is the desktop's answer and there is no
wheel on a tablet.

The develop status strip was 28px against the 44px headers on the
library and settings pages either side of it — the one screen where a
way out has to be found was the one drawn smallest. All three now agree.

Verified with cargo test -p dr-ui (192 passing, 6 new), clippy at
-D warnings, and an arm64-v8a release build packaged to an APK.

Raw Blame History

Requirements traceability matrix

Denominators are parsed from requirements.md at run time, never hardcoded. Coverage is the intersection of tagged and defined IDs over defined IDs, so it cannot exceed 100%.

Summary

Metric	Value
Source files scanned	93
TRACES tags found	137
Requirements defined	149
Requirements covered	70
Coverage	47.0% (70/149)

Orphan tags

A tag naming an ID requirements.md does not define — what renumbering produces, and what a typo produces.
