The bottom row of the grid was often blank, at a scroll position the user could sit at indefinitely. Two numbers decided when the loaded window follows the view, they lived in different languages, and they disagreed. The grid loaded three screenfuls and Rust held the window still until the first visible cell was three quarters of the way through them. Three quarters of three screenfuls is 2.25, and the view itself is one screenful tall — so the bottom of the screen had already travelled a quarter of a screenful past the last loaded cell before anything moved. Those rows are not in the model, so nothing is drawn for them. The same margin was wrong upward, and exactly so. The window is placed a quarter of itself behind the view, and the margin then declared the view too close to the top at precisely that distance: every single row scrolled upward re-read the catalog, rebuilt all 360 cells and re-queried their badges and ratings, and so did the row after it. So the grid now reports what it shows — a screenful, counting the row the scroll position has cut in half, which `visible-rows` alone undercounts and which is exactly the row reported missing — and Rust owns the rest: four screenfuls loaded, placed a quarter back, and moved once the view comes within half a screenful of an edge of them. One decision in one place, and the test now walks the view the length of the library and asserts the window covers it at every step. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

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.
