A tag was any line containing the string, so the traceability tool scanned tools/ -- its own source -- and its test fixtures became coverage. R1 and NFR-OPS-1 were tagged on nothing but that. Four requirements had sites that were never implementations: the same fixtures also fed FR-CAT-1, FR-CAT-2 and NFR-P1, gestures.rs fed FR-UI-4 from a push_str, and build.rs fed FR-DEV-3a and FR-DEV-3c from the tag it emits into generated code. A tag is now a comment whose first word is TRACES:. Excluding cfg(test) was rejected because tags on tests are this project's recommended practice, and keying on string literals was impossible because schema.rs carries six genuine tags inside Rust strings -- the SQL it embeds is commented with --. Four tags removed as unearned: FR-CAT-13 (no XMP is parsed or written anywhere), FR-PLAT-AND-1 (SourceRef::Document is constructed only in test modules, and the second tag sat on imports_supported, which documents the absence). Two added as earned: NFR-A11Y-3, which was built and untagged, and FR-PLG-8's preservation clause. Four requirements amended rather than built, each with its reasoning: R5's tiling clauses struck, NFR-P11 naming the state that must survive, FR-RAW-2's mechanism reworded to bytes-in, FR-EXP-1's AVIF and JPEG XL stated as post-v1. Coverage falls 122 to 120 of 179, and means more than it did. 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.
