A pinch is not one zoom step, it is a stream of them, and every step changes both the column count and the capacity — two reports. Each report re-queried the catalog, rebuilt all 360 rows of the model, re-read the badges and ratings for every one of them and spawned a thumbnail batch, synchronously, on the thread trying to draw the frame. Twice per step. That is why zooming juddered while scrolling the same grid is smooth: a scroll reloads a few times per screenful, a zoom reloaded twice a frame. None of that work is urgent, because none of it is about which photographs are on screen. The window holds the same images however they are laid out — the model already has them, and the cells re-flow from `columns` and `cell-size` with Rust not involved at all. What the reload actually recomputes is which cells begin a row, so the month headings land correctly, and which thumbnail size class to ask for now. Both can wait for the gesture to finish, so both are now coalesced behind a single settle timer: replacing the timer drops the previous one, and only the last report of a run lives long enough to fire. The anchor is captured on the first report of a run rather than read when the timer fires. As the grid re-flows the viewport keeps its pixel offset while the rows move underneath it, so the view drifts and reports the drift; reading the anchor at the end would faithfully return to wherever it had wandered. Taking it at the start returns to the photograph the user was looking at when they started the gesture.
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.
