A clone gets the texture right and the level wrong. Dust on a gradient sky is copied from a patch a little lighter than the hole it fills, and the repair reads as a disc even though every grain in it is correct — which is why FR-DEV-8 asks for heal and not only for clone. Heal adds the membrane: the difference between the two neighbourhoods, sampled at twenty-four points around the rim and interpolated across the disc by inverse square distance. Solving the Poisson problem properly is tens of Jacobi iterations, and an iteration here is a dispatch — sixty dispatches to remove a dust spot is not a frame budget. The closed form costs one loop over the rim, no state, and no second pass. The spec called for mean-value weights; inverse squares are two transcendentals per sample cheaper and agree wherever the boundary difference varies smoothly, which is every repair anyone makes. What decides whether that trade holds is the measurement, so the measurement is the test: on a ramp steep enough to leave a clone wrong by 38 levels out of 255, the heal is wrong by 0. docs/spot-removal.md §6.1 records what shipped and what it would take to go back.

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.
