Two halves of the same complaint: a preset sheet that opens on "No presets yet" is homework, and a photographer with ten years of presets in Lightroom has no way to bring them. `dr-preset-xmp` reads Camera Raw `.xmp`. The mapping turned out to be mostly a rename rather than a conversion, because Adobe and this pipeline already agree: exposure is in stops in both, and contrast, the four recovery controls, clarity, texture, vibrance and saturation are all ±100 in both. That is not imitation, it is the convention raw developers converged on — `highlights_shadows.yaml` cites it in as many words. Only sharpening needed arithmetic, Adobe's 0…150 against our 0…100. The white balance does not come across, and says so rather than guessing. Adobe writes absolute Kelvin for a raw file where ours is a relative nudge from what the camera recorded, so converting needs the *target image's* as-shot white balance — exactly what a preset cannot carry, since the same preset lands on a frame shot at 3200K and one shot at 7000K. A guess would be wrong on most images and invisibly so. A folder is read as readily as a file, nested, because that is the shape an exported preset folder is in and importing ninety files one at a time is asking someone not to bother. `dr_pipeline::starter` is six presets a first run begins with, written against this pipeline in its units and deliberately mild — a starting point, not a caricature. They are seeded when the library *file* does not exist rather than when the library is empty, so deleting all six does not hand them back on the next launch. Both of these name operations, and `ui_names_no_operation` was right to stop them living in `ui/`. That test exists because the failure is silent and cumulative, and it caught exactly what it was written for: a preset called "Punch" is a statement about contrast, clarity and vibrance, and a table mapping Adobe's vocabulary to ours is a statement about the pipeline. Neither is a fact about an interface. So the starter set went into `dr-pipeline`, and the importer into its own crate — between two walls, since `dr-pipeline` depends on nothing on purpose and XMP is real XML not worth hand-rolling.

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.
