An edit used to be a bag of scalars. That stopped being true when the mask stack and the film stock arrived, both deliberately held apart from `ops` because a layer is not a scalar and a stock is not a scalar — and nothing announced the change. What happened instead is that three routines each captured "the edit" and each captured a different subset of it. `EditState` is all of it: the parameter map, the masks, the stock. What keeps it complete is not a comment. `EditGraph::state` destructures the graph exhaustively, `EditGraph::set_state` destructures the state exhaustively, and the fields are public so every construction site is a struct literal naming all of them. Adding a fifth kind of graph state — FR-DEV-8's spot removal is the one already asked for — fails to compile until somebody has decided whether an undo has to put it back. Verified both ways round by adding a field to each type and watching five call sites refuse to build. A compiler error rather than a runtime check, because the failure being prevented is silence: the missing halves produced no panic, no warning and no failing test. The stack is now shared rather than owned, and that is about the drag path rather than memory: `state` runs on every parameter change, which during a drag is once a frame, and deep-copying a painted brush sixty times a second to record an exposure move would be a cost paid for nothing. `masks_mut` is the one door a stack is modified through, so it clones on write. `FilmRebake` is the one thing a caller is still owed. Restoring a stock always needed the profile database this crate does not link (ARCH §6.5a); it was a comment before, and it is a `#[must_use]` return value now.

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.
