The grid now zooms, which needs thumbnails at two resolutions rather than one, and exposed a scrub that landed in the wrong place. **Two thumbnail size classes.** `ThumbSize::Grid` (256px, ~10 KB) and `Large` (1024px, ~45 KB), with the class part of the store key so both coexist. Storing everything large would take the reference library from ~200 MB to ~860 MB, and shards sync, so that is transfer cost on every device rather than only disk. A store written before the class existed migrates in place: its entries are all grid-sized, which is what the column defaults to, so nothing already fetched is discarded. `forget` now drops every size for an image. Reading a single row left the other class's bytes on the shard's tally for good, sealing it early on space nothing occupied. **Grid zoom.** Ctrl+wheel and pinch resize cells between 90px and 420px in geometric steps, so the gesture feels the same at either end where a fixed pixel step would be imperceptible at 400px and violent at 90px. Crossing 256px switches to the large class, so a zoomed cell is sharp rather than upscaled. Columns and window capacity already derived from cell size, so the grid reflows for free. **The scrub landed about half a library too high.** It counted only dated images while the grid shows all of them — 10,733 dated against 19,841 rows — and ignored `shadowed_by`. Verified against the live catalog: the old formula gave 10,887, the new one 10,732, the true grid position 10,732. The scrub's count and the grid's window must use identical predicates and ordering; a test now fails if they diverge. **Timeline gestures are continuous.** Scrub and pan were quantised to whole buckets, so a slow drag did nothing until it crossed a boundary and then jumped a month. Both work in fractions of the visible span now, and pinch-to-zoom arrives for tablet, where there is no wheel to reach the axis with. The pinch accumulator was wrong on first writing: it took at most one step per update, so an 8x spread — three doublings — yielded one zoom level. `log2().trunc()` now extracts every whole doubling and carries the remainder. The original test asserted the wrong number and defended it in a comment, which is worth remembering: a test can entrench a bug as readily as catch one.

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.
