The APK carried no Java of its own -- the only dex in it was Slint's -- which blocked FR-PLAT-AND-4's foreground service and FR-PLAT-AND-6's outbound half alike. assemble-apk.sh now compiles everything under android/java against android.jar and has d8 merge it with Slint's dex into one classes.dex. With no .java in the tree the step is skipped and the APK is byte-for-byte what it was. -source 8 -target 8 -bootclasspath android.jar is load-bearing: from -target 9 javac rejects -bootclasspath, platform classes then come from the JDK instead of android.jar, and the build stays green while the device raises NoClassDefFoundError. FR-PLAT-AND-6 with it: VIEW, SEND and SEND_MULTIPLE filters, the launch Intent read over JNI before Slint is given the app, and a hand-written ExportProvider rooted at getFilesDir() rather than AndroidX FileProvider, which would have meant Gradle. singleTask, because the new filters let another app launch the activity while it runs and the default mode would start a second android_main, Slint backend and wgpu device in one process. Classes load through the activity's loader; FindClass on android_main's thread sees only the system loader. The share half has no caller yet and is deliberately untagged. The five tests read the manifest and the Java through include_str!, so they fail if a filter goes, if the activity stops being singleTask, if the provider becomes exported, or if the authority and the class drift apart. Verified: javac, d8 and a real dex merge run against the host SDK; aapt2 link over the manifest; clippy -D warnings clean; 5 tests pass. Not verified: anything needing a device.

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.
