DemosaicedImage gains a second producer, from_rgba8, alongside the CFA path. Nothing about the type is CFA-specific — it is "an image on the GPU, ready to adjust" — which is what lets develop mode work on a JPEG without the edit graph or any operation knowing the source was not a RAW file. The one real difference is the transfer function: sensor data is linear, a JPEG is gamma-encoded. Every operation assumes linear scene-referred colour (exposure is a multiply, and doubling a gamma-encoded value is not a stop), so the shader prologue linearises once, at the only point where the two source kinds still differ. The flag rides in as_shot_wb.w, which was padding. For a JPEG the white balance uniform is neutral and the colour matrix is identity, so both stay unconditional multiplies rather than becoming branches. max_dimension is exposed because it is a hardware limit the caller must plan around, not a failure to report afterwards: a 13728x8928 film scan exceeds the common 8192 texture limit, and fitting it first is the only way to develop it at all.

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.
