The rest of FR-DSP-8. The develop session now carries the space its canvas is encoded into, and `render` composes for it instead of for sRGB — which is the whole of the change to the pixel path, because the output space was always a parameter of composition and always entered the structure hash. A display change is a recomposition. The space is set on the way into every render rather than pushed when the window moves, so a photograph opened while the window already sits on the second monitor is right on its first frame instead of flashing the wrong colour until the next poll. Which display that is comes from sampling the window's position and scale factor twice a second — Slint reports neither a move nor a display change — and re-surveying only when they differ. Settings shows what came back under ABOUT: the display, the space, why, and the other monitors, because the failure FR-DSP-8 names is one that is invisible from the display you are reading the page on. Fractional scaling: the canvas is now rendered at the physical pixel size of the box it occupies rather than the logical one, so the compositor presents it 1:1. At 1.25 it was previously handed 1600 samples to fill 2000 device pixels, and the softness that produces reads like a bad demosaic rather than like a scaling bug.

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.
