`dr-sync` defines `RemoteBackend` and a capability model the engine adapts to, so a second backend can be added without touching the code that uses one. That boundary was documentation. Seven files in `dr-ui` constructed a `NextcloudBackend` directly, ten functions took one by concrete type, and exactly two call sites in the tree — both inside `dr-sync` itself — ever held the trait object. A WebDAV or local-folder backend would have had a well-written trait to implement and nowhere to go afterwards. The change is smaller than the finding suggests, because the trait was already right. Every method the UI has ever called on a backend — `get`, `put`, `list`, `delete`, `create_dir`, `move_to` — was already on it, so nothing had to be added and no behaviour moved. Ten signatures widened to `&dyn RemoteBackend`, sixteen constructions became `remote::connect`, and `remote.rs` is now the only file in the interface that names a connector. `connect` returns `Result<Box<dyn RemoteBackend>, RemoteError>`. The error type is `dr-sync`'s rather than the connector's, which is why every call site kept its shape — the `match`, the `let Ok(..) else`, and `.map_err(ScanFailure::local)?` all still read as they did. One wrinkle worth recording: `&Box<dyn Trait>` does not reach `&dyn Trait` on its own. The compiler reaches for unsizing, which wants `Box<dyn RemoteBackend>: RemoteBackend`, and reports a confusing missing impl rather than suggesting a deref. Twelve call sites therefore say `&*backend`, and two say `let backend: &dyn RemoteBackend = &*backend` where a borrow is shared across lanes. What this does *not* do is abstract credentials. `AppCredentials` is an app password from Login Flow v2 — a Nextcloud protocol, not a general notion of authenticating to a remote — and seven files still name it. An OAuth token, a bucket key pair and an app password have no useful common shape, so deciding what an account is across backends before a second one exists would be a confident guess. code-health.md CH-2 now records that as the remaining half, and it should wait for the backend that forces it. Verified: fmt clean, clippy clean at -D warnings, 2041 tests pass. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Building
Desktop:
cargo run -p darkroom-desktop
Android (containerised toolchain, see docker/android):
./docker/android/build.sh cargo ndk -t arm64-v8a build --release
Current state
Working: workspace, GPU context and compute pass, adaptive Slint shell, Android cross-compilation of the core crates.
Not yet working: the zero-copy display path. The build currently uploads frames through the CPU, which is exactly what ARCH §6.1 forbids — measured at 96% of frame time at 4K. Replacing it is spike S1, the project's highest priority.
cargo run -p dr-gpu --example bench --features readback
reproduces that measurement.
