The other half of the blank bottom row, on a library still filling its thumbnail store: the cells were in the model, and nobody had asked the server for them yet. A batch is fetched one image at a time, two round trips each, and it is abandoned wholesale the moment the window moves. Issued in model order, the front of that queue was the quarter-window of cells sitting *above* the view — which nobody is looking at — and the back of it was the bottom of the screen and the screenfuls below. So the last rows of the grid waited behind three quarters of a window's worth of fetches for photographs off screen, and every scroll threw the queue away and started over from above the view again. For as long as the scrolling continued, the bottom of the grid could be starved. The rows still address the model they were built against; only the order they are asked for in changes. On screen first, in reading order, then the rows below the view, then the rows above it. Below before above because that is where the view is going — scrolling back over cells already fetched is served from the store, and from `requested` without a fetch at all.

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.
