The timeline's bars, the filter chips' counts, the "on this device" count and whether the scoped collection is pinned all describe the *library*. None of them can change because the view scrolled. `load_window` recomputed all four every time the window moved, which is several times per screenful. Together that is a `MIN`/`MAX`, a `GROUP BY`, two counts, and under a collection three more queries — about 8 ms of SQLite on the thread that is trying to draw the frame, for four answers that were already on screen and already right. They are now keyed on what they actually depend on: the scope, the filter, whether this is the trash, and the total. The total earns its place as the change detector as much as for the scrollbar — a scan landing, a delete or a restore all move it, and it was already read on every load. What a total cannot see is a rating edited under an unchanged count. That is covered, and deliberately not by widening the key: `apply_judgement` already refreshes the chips itself, because it has to report what actually landed rather than what was asked for. Same for the axis — a zoom, a pan, a scrub and dates arriving from the thumbnail worker each call `refresh_timeline` directly. Skipping the recompute here cannot leave anything stale on screen.

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.
