A history state was a Preset — a map of scalars — which was right while every edit in the graph was a parameter. A spot is not one, and undo is the first thing anyone does with a repair: place it, dislike it, take it back. Left as it was, that press would have stepped some unrelated slider and left the spot on the photograph, which reads as undo being broken rather than as undo being absent. So a state is now the pair, params and spot set. The same door is the one the mask stack will come through: mask edits are outside undo today for exactly this reason, and FR-DEV-5 is not finished until they are not.

Status: early. v0.1 is a remote library viewer — see docs/milestone-v0.1.md.
Documentation
| Document | Contents |

| requirements.md | What the software must do — 122 numbered requirements |
| architecture.md | How it is built — crates, GPU pipeline, data model, sync |
| milestone-v0.1.md | The first buildable milestone |
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.
