dtourolleandClaude Opus 5 1297e3259b Stop claiming the app crates cannot cross-compile
The note above the core-crate check said the UI and app crates would join
"once the Android shell exists". They already had. Building `darkroom-android`
for aarch64 takes 4m23s and produces `libdarkroom.so`, linked for Android 28 —
which is what the step below now checks, and what a device installs.

Rewritten to say what the core check is actually for: a fast, link-free gate
that fails early and names a smaller suspect, ahead of the full build.

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.
