`@tr(` appeared zero times in 14,482 lines of markup. Every string the user
reads was a literal, so NFR-A11Y-1 was not partly done or done badly — there
was nothing to extract and nothing a translator could have been given.
The mechanism turns out to cost almost nothing, and the reason is worth
stating because it decides the order of the work: a string written `@tr("Sign
in")` is already correct in a build with no translation at all. Slint's
`translate()` formats the original and hands it back when neither delivery
path is active, so a converted string and a literal are the same string until
someone writes a `.po`. That means the interface can be converted a screen at
a time rather than in one 14,000-line commit that nobody can review, and every
intermediate state is shippable.
So the delivery half is wired and left inert. `build.rs` asks for bundled
translations only once `lang/<lang>/LC_MESSAGES/dr-ui.po` exists — the first
catalogue anyone commits turns it on with no build-system change, and until
then a checkout with no `lang/` builds exactly as it did. Bundling rather than
the `gettext` feature because of Android: under ARCH §6.9's storage model
there is no path a `.mo` could sit at that the app can reach, and no C library
to link it against. The extraction command and the one flag that must not be
passed to it are recorded in the module docs.
The launch screen is converted whole: 32 calls covering every heading, button,
caption and placeholder. It goes first because it is the screen a user cannot
get past — an unreadable preferences page can be ignored, an unreadable sign-in
cannot. Four kinds of literal are deliberately left alone and the file says
which: the product name, example values whose shape is the message, `..`, and
the path separator.
Two things this leaves open, recorded rather than papered over. The headings
carry their own capitals, because `PanelHeading` draws what it is handed — so
a translator supplies "SERVEUR", not "Serveur", and styling in the string is a
real cost now paid rather than a surprise later. And `@tr()` is markup only:
the operation and parameter labels NFR-A11Y-1 names explicitly resolve in
`labels.rs`, in Rust, because the core may not depend on a localisation
library — those need a second mechanism, and it is not built.

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.
