The second thing standing between `android_main` and the first `poll_events`, and the one that grows with the library rather than with the APK. `library_ui::open` called `show_catalog_now`, which called `Catalog::open_verified`. That runs `PRAGMA quick_check`, which reads every page of the database, and then `Catalog::open`, which takes a full SQLite backup of the file before a migration and rewrites its structure afterwards. On a 50,000-image library that is tens of megabytes of I/O on a tablet's flash, and it happened before the window had painted anything — so on Android it was counted against the five seconds the input dispatcher allows, and on the desktop it was a launch that sat on a blank window. `dr_catalog::recovery`'s own module documentation says the check is affordable "at startup, where a failure has a user in front of it who can answer a question". That was the intent and it was not true: there was no interface yet in which to ask. Now there is, because the open happens on a worker and the answer arrives on a channel drained by a timer — the same shape the scan, the thumbnails and the login already use. The gate the synchronous call provided is kept, and is the reason the scan moved with it. `Catalog::open` succeeds on a damaged file whose header survived, so a scan running beside an unanswered recovery question writes ETags and image rows into damaged pages and turns a catalog that had a backup into one where the backup is the only copy left. So the scan now starts from the drain, on the two answers that permit it, and not at all on `Corrupt`. `library-scanning` stays true throughout, which hides the Rescan button and stops the gate being merely advisory. What the user sees while it runs is a third empty state. The grid already refused to conflate "still scanning" with "scanned, found nothing"; "opening the library" is a third answer and it gets its own sentence, because a grid saying "Scanning…" while nothing is on the network is the same kind of lie the other two were separated to avoid. `show_catalog_now` stays, unchanged and blocking, for `recovery_ui`. That call site has the event loop running, has just replaced the file under a `forget_catalog`, and has `recovery-busy` on screen — the same reasoning `recovery_ui::answer` already gives for doing its file copy in place. The part both paths share is now `adopt_catalog`. One consequence worth naming: the cache-usage figure on the settings page was read at startup from a catalog that is no longer open by then. It moves to the page's `on_open` closure, beside the face coverage, which is read there for exactly the same reason — it is only ever looked at while that page is on screen.

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.
