The adjust pass and the readback both scale with pixel count, so a drag paid full viewport cost on every frame it managed to produce. Halving each edge while the gesture is moving is roughly a quarter of the work. Detecting the gesture needed no new plumbing. No control reports a drag boundary, and threading one out of every slider, curve point and crop handle would be a lot of surface for what is a rendering concern. The coalescing flag already carries the answer: a request that arrives while a render is queued can only come from a control that moved again. A click, a reset or a resize never coalesces, so those still render sharp the first time and never show a draft frame. A settle render restores full resolution 120 ms after the last change — above the interval between events within a drag, so an ordinary gesture never trips it mid-motion, and well under the point where waiting for the sharp frame would be noticeable. Only one settle is ever queued. The softness is therefore visible only while the image is moving too fast to study. dr-ui tests pass.
DarkRoom
A cross-platform, non-destructive RAW photo editor for Linux and Android.
Status: early. v0.1 is a remote library viewer — see docs/milestone-v0.1.md.

Building
Desktop:
cargo run -p darkroom-desktop
Android (containerised toolchain, see docker/android):
./docker/android/build.sh cargo ndk -t arm64-v8a build --release
Current state
Working: workspace, GPU context and compute pass, adaptive Slint shell, Android cross-compilation of the core crates.
Not yet working: the zero-copy display path. The build currently uploads frames through the CPU, which is exactly what ARCH §6.1 forbids — measured at 96% of frame time at 4K. Replacing it is spike S1, the project's highest priority.
cargo run -p dr-gpu --example bench --features readback
reproduces that measurement.
