A spot is a disc, a source offset and four numbers, and it lives beside `ops` for the reason `masks` and `film` do: the operation trait is ParamId -> f32, and a list of repairs is neither scalar nor fixed. Two decisions here are not obvious. The id is derived from the position rather than counted, because two devices editing offline would each mint `spot3` for different marks and the sidecar merge would then treat two repairs as one — from the position, two devices that removed the same piece of dust agree, and two that removed different ones do not. And every length is in the frame's isotropic units, not a mixture of those and shorter-edge fractions: one unit for the radius, the feather and the offset agrees on a landscape frame and on a portrait one, where a mixture only agrees on the first. `rounds` is the arithmetic that keeps a source from reading a destination. Every spot in one pass reads the photograph as it stood before that pass, so a spot sourcing from an earlier spot's destination would copy the mark that spot was removing. Grouping is not a pass per spot — that is sixty-four dispatches for a case that almost never arises — it is a new round only when the sources actually collide.

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.
