dtourolleandClaude Opus 5 954246b969 Register the inference requirements, and format the fill test
Two CI gates have failed on every push since 0.13.4 and both are
fixed here.

The traceability gate rejected `FR-INF-1` as an orphan: settings.slint
and dr-ui tag it, but the four register entries inference.md §12 wrote
were never carried into requirements.md, which is the only file the
extractor reads. §3.12 and §4.10 now hold FR-INF-1..3 and NFR-INF-1
verbatim, with the acceptance milestones pointed back at inference.md.
The matrix is regenerated (188 defined, 155 covered) and the README's
"where it stands" line, which the 0.13.6 release commit skipped, says
0.13.6 and the new figures.

`cargo fmt --check` failed on the `fill_border` call in dr-pano's
padding test, which is the first thing the Desktop job runs after
installing the toolchain and why it failed within a minute.

# DarkRoom
A non-destructive RAW photo editor and library for Linux and Android, with a
GPU develop pipeline, a catalog that syncs between devices, and no account,
no telemetry and no cloud of its own.
[![The library: seventy frames, the timeline beside them, the filter bar above](docs/manual/media/library.png)](docs/manual/README.md)
**[The manual](docs/manual/README.md)** shows every feature, pictured from
the application itself. This page says what it is, how to get it, and what
is still missing.
## What it does
**A library.** Point it at a folder — on this machine, on a network mount,
or one a Nextcloud client keeps in virtual-files mode, where a placeholder
is treated as the photograph rather than as a one-byte file — or at a
Nextcloud account directly. The grid is virtualised, ordered by capture
time with a timeline beside it, and filtered by rating, flag, person and
whether the file is here. Ratings, keywords, collections and a
trash that survives a crash mid-operation. Card ingest. Bursts fold. Face
detection and identity, with the index syncing between devices.
**Developing.** Eighteen declared operations fused into one compute
dispatch, plus the neighbourhood work that cannot be: clarity, texture,
capture sharpening, noise reduction, lens correction, spectral film
simulation. Crop and straighten, spot repair, and local adjustments over
masks the model draws — click a subject or a category, then paint, subtract
a gradient, grow or shrink the edge. Focus peaking and a raw histogram for
judging what is recoverable. Named presets; XMP sidecars other editors read.
[![Segmenting an urban scene and choosing the sky as a mask](docs/manual/media/local-segment.png)](docs/manual/README.md#local-adjustments)
**Panoramas.** Select the frames, align, choose a projection, fill the
ragged border rather than crop it, and the composite lands beside its
sources as a DNG, with a sidecar recording what it was merged from.
[![Twelve hand-held frames aligned on a cylinder](docs/manual/media/panorama-aligned.png)](docs/manual/README.md#merging-a-panorama)
**Export.** JPEG, PNG, AVIF, JPEG XL, 8- and 16-bit TIFF, with resize, output
sharpening, a naming template and a colour space — to a folder here or back
into the library.
**On both platforms.** The same core runs on a desktop and a 12-inch
tablet; the interface is one layout, tuned for a wide viewport with touch
targets throughout. On desktop the develop view draws the compute pass's
texture directly — no readback between the GPU and the screen.
## Getting it
| Platform | How | State |
|---|---|---|
| Arch Linux | [`packaging/PKGBUILD`](packaging/PKGBUILD) — `makepkg -si` | Built from every release |
| Android | The APK from each CI run, or `./docker/android/package.sh --install` | Runs on a tablet; F-Droid not yet submitted |
| Windows | `DarkRoom-<version>-x86_64-setup.exe`, cross-built by CI ([windows.md](docs/windows.md)) | Verified under Wine only; unsigned |
| Flatpak | [`packaging/flatpak/`](packaging/flatpak/) | Manifest in tree; choosing a library does not yet work in the sandbox |
Or build it. Git LFS is required for the model weights, and the toolchain
pins itself to 1.92.0:
```bash
git lfs install && git lfs pull
cargo run --release -p darkroom-desktop
```
Android, through the containerised toolchain ([docker/android](docker/android/README.md)):
```bash
./docker/android/build.sh cargo ndk -t arm64-v8a build --release
```
[CONTRIBUTING.md](CONTRIBUTING.md) has the system packages, the four
commands CI runs against what you send, and the shortest useful
contribution — a develop operation is one YAML file, and it arrives with its
controls, its place in the chain and its tests.
## Where it stands
**0.13.6**, twenty tagged releases in. 188 numbered requirements in
scope, 82% of them claimed by code and [traced to it](docs/traceability.md);
the rest are written down rather than merely absent.
**Not built:** plugins (post-v1, [D12](docs/requirements.md)), compare and
survey culling, AI denoise, tiled and progressive rendering, HDR merge and
focus stacking, most of the Android platform integration beyond running,
and the Flatpak's library chooser. The performance targets are half
verified: the per-commit benchmark suite §8 requires exists for everything
that does not need a frame — the catalog, the scan, the thumbnails — and
not yet for the render path, so a regression there fails nothing.
[outstanding.md](docs/outstanding.md) is the list, with the reasoning for
each.
**The one deliberate compromise worth knowing about before reading
anything else:** the Android develop view reads its 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 — [technical-debt.md TD-1](docs/technical-debt.md)
has the measurements and the three things any one of which would remove it.
## Documentation
For someone using it:
| | |
|---|---|
| [manual](docs/manual/README.md) | Every feature, pictured |
| [gestures.md](docs/gestures.md) | How it is driven — generated from the code, so it cannot describe a gesture that does not exist |
For someone changing it:
| | |
|---|---|
| [CONTRIBUTING.md](CONTRIBUTING.md) | How to land a first change without reading the rest |
| [requirements.md](docs/requirements.md) | What the software must do — the numbered register, and the decisions |
| [architecture.md](docs/architecture.md) | How it is built — crates, the GPU pipeline, the data model, sync |
| [technical-debt.md](docs/technical-debt.md) | Compromises taken deliberately, each with the condition that retires it |
| [outstanding.md](docs/outstanding.md) | What is not built, and whether that is a decision or a gap |
| [code-health.md](docs/code-health.md) | What a contribution costs, per seam, measured |
| [traceability.md](docs/traceability.md) | Generated: which requirement is claimed by which file |
