Remote browsing must not transfer whole RAW files. The obvious shortcut — fetch a fixed prefix and hope the preview is inside — does not work: an embedded JPEG typically starts a few hundred KB in and runs for one to three MB, so a truncated fetch yields a JPEG whose scanlines stop partway down. Decoders render what they have rather than erroring, so the failure looks like a corrupt image rather than a short read. This reads the TIFF-structured containers — CR2, NEF, ARW, DNG, ORF — and returns an exact byte range for a Range: request. CR3 is ISO-BMFF and declines to the caller's whole-file path, which is correct if slower; a locator returning a wrong range would be far worse than one that declines. Every offset read from the file is bounds-checked against the real file length rather than trusted (NFR-SEC-1). Assisted-by: LLM
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.
