Zooming the develop view changed the exported file. `Framing::view` is kept out of the sidecar, out of `is_active` and out of `output_size` precisely so that it cannot — but those exclusions keep it out of the *edit*, and an export is a *render*. `visible_rect` deliberately folds the view into the single rect the fused shader's prologue samples, so `render_for_export` inherited it: at 4:1 it wrote the middle of the frame, magnified to fill the file at the full output size, with the detail kernels scaled four times over because `render_scale` folds the view in as well. `render_thumbnail` did the same to the grid. `render_uncropped` already suspends the view for this exact reason, so the fix is its pattern: one `render_the_file` that both file-producing paths go through, composing inside the suspension since the view reaches the shader as a uniform baked at composition time. Restored whatever happens — leaving the graph un-zoomed after a failed export would throw away where the photographer was looking. Nothing caught it because the guard checked the wrong things. `zooming_does_not_change_the_exported_image` asserted the output size and the crop; both held perfectly throughout. Renamed to `zooming_does_not_change_the_size_or_the_crop`, which is what it tests, and the pixels are now guarded where pixels exist. The new test uses a ramp rather than quadrants deliberately: a four-quadrant frame is self-similar under a centred zoom, and the first version of this test passed against the bug because of it. Traces FR-EXP-9, which asks for the full-quality pipeline "regardless of what the display was showing". Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
DarkRoom
A cross-platform, non-destructive RAW photo editor for Linux and Android.
Status: 0.9.0, and no longer a spike. A library opens, culls, develops and exports on both platforms, across eight tagged releases. What is not built is written down rather than merely absent — see docs/outstanding.md for the requirements that have no implementation and why, and docs/technical-debt.md for the compromises that were chosen.

Building
Desktop:
cargo run -p darkroom-desktop
Android (containerised toolchain, see docker/android):
./docker/android/build.sh cargo ndk -t arm64-v8a build --release
Git LFS is required for the model weights, and the toolchain pins itself. CONTRIBUTING.md has the details and the four commands CI will run against what you send.
Current state
Working. A catalog over a local folder, a Nextcloud account, or a folder a
sync client keeps in virtual-files mode — where a placeholder is treated as the
photograph rather than as a one-byte file. A virtualised library grid with a
capture-time timeline, ratings, labels, keywords, collections and a trash that
survives a crash mid-operation. Card ingest. Face detection and identity, with
the index syncing between devices. A develop pipeline of fifteen declared
operations fused into a single compute dispatch, plus the neighbourhood
operations that cannot be — clarity, texture, capture sharpening, noise
reduction, lens correction, spectral film simulation. Crop, straighten, spot
removal, gradient and subject-segmentation masks, named presets, and a
generated panel that no operation in ui/ is allowed to name. Export to JPEG,
PNG and 8- or 16-bit TIFF with resize and output sharpening.
The zero-copy display path works on desktop. The compute pass writes a texture that Slint composites directly, which is what ARCH §6.1 requires; the readback it forbids costs 96% of frame time at 4K, and
cargo run -p dr-gpu --example bench --features readback
still reproduces that measurement. The one exception is the Android develop view, which reads the frame back through the CPU because zero-copy there needs wgpu's Vulkan swapchain, and that tears a portrait window on a tablet whose panel is mounted landscape. It is debt, not a revision of the rule: the reasoning, the on-device measurements that forced it, and the three separate things any one of which would remove it are in technical-debt.md TD-1.
Not built. Plugins, compare and survey culling, focus peaking, burst grouping, AI denoise, tiled and progressive rendering, and most of the Android platform integration beyond running. The performance targets in §4.1 are unverified rather than unmet — the per-commit benchmark suite §8 requires does not exist, so nothing fails a build on a regression. docs/outstanding.md is the list, with the reasoning.
