Two faults left over from making the gesture reach the grid at all. **It still opened photographs.** Checking the finger id stops the synthetic release Slint emits when the *second* finger lands, but not the other end of the gesture: lifting one finger of two leaves the other one down, and Slint replays that survivor as a fresh `Pressed` on whatever is under it — which is how it hands the pointer back to ordinary handling. Under it is a cell. So the cell was selected, and lifting that last finger was a complete, well-formed click on the same finger that pressed. No part of the event stream distinguishes it from a real tap, so the grid now remembers that a pinch just happened: a latch raised when the gesture starts and lowered a beat after it ends, during which cells take neither presses nor clicks. The press that *opens* a pinch is undone rather than suppressed — it has already happened by the time a second finger makes it a pinch. Undoing it has to be exact, or a cancel that restored the selection but left the anchor moved would make the next shift-click select a run from a cell nobody pointed at, so capture and restore are a tested pair. **And it was not smooth.** Two reasons. The pinch was thresholded into ±1 steps of 25%, so the grid lurched and then sat still; it now takes the ratio since the last update and tracks the fingers, with the drawn cell still landing on whole column counts because the columns divide the width. And `zoom-cells` was the one geometry change still reloading inline — a full catalog re-read, 360-row model rebuild and thumbnail batch per step, on the thread drawing the frame. It goes through the same settle timer as the rest now.

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.
