A colour square wave built from equal, opposite swings of red and blue is not a pure colour pattern: Rec. 709 weights them 0.2126 and 0.0722, so it carries a luminance square wave of about a seventh of the swing underneath. Correlating the raw red channel therefore reads a constant floor that the chroma filter is not meant to remove, which compressed every ratio towards one - enough that the resolution test could no longer tell a correct kernel from one twice the size. Correlate the colour difference instead, and write the derivation of each expected value into the test.
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.
