The counterpart to the grouping: where the signatures come from, and how a group reaches a cell. Signatures are computed from the 256px thumbnails dr-thumbs already holds -- vastly more resolution than a 9x8 reduction can use -- so a library that has been browsed, or that has synced somebody else's shards, has already paid for them and no RAW is decoded for this. The consequence is stated rather than hidden: an image with no thumbnail gets no signature and never joins a burst. That is self-correcting, and it is why the pass runs when the thumbnail sweep finishes rather than on a timer. Nothing happens at import and nothing happens at query time. The mark is drawn as a child of the cell's TouchArea, for the same reason the star strip is: a click on it must not also reach `cell-clicked` and throw the user into develop, and children are hit-tested before the element they sit in. It is never hidden on hover the way the stars are -- a collapsed burst stands in for frames that are not on screen, and something has to say so whether or not a pointer is nearby. Folding changes what the grid's *query* returns rather than what its cells draw, because the grid is a window over an ordered query and the frames a fold hides are mostly not loaded. So the predicate joins VISIBLE in every query that lists or counts cells -- the window, the header's count, the run a shift-click resolves, and the ordinal a scrub lands on -- under the discipline VISIBLE's own comment sets out: present in four places of five is worse than absent, because the counts disagree with the cells and neither looks wrong on its own. There is a test for exactly that. `the_window_read_walks_the_ordering_index` now includes the burst clause. It asserts on the query plan while holding its own copy of the query, so left alone it would have gone on reporting green against a query the grid no longer runs. If the clause costs `images_grid_order` and puts the sort back, that fails here rather than becoming jitter someone measures in six months. The pass keeps its own drain timer in a thread-local instead of taking fields on the library controller, so everything the feature needs to run lives in one file and the screen that starts it holds nothing.

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.
