FR-CULL-3's focus peaking. One compute dispatch measures local contrast in WGSL and writes an overlay texture; on desktop it reaches Slint through the same zero-copy wgpu import the canvas uses, so nothing per-pixel touches the CPU on the frame path. With peaking off the cost is zero and structurally so: focus_overlay opens with `let settings = self.peaking?;` before the frame is touched, and clearing drops both overlay textures, so no VRAM is held either. NFR-P14 is met by construction rather than by measurement -- one dispatch, no second render, no pipeline compile after session open, and a test asserting allocations stay at 2 over eight frames. The budget test asserts 50ms at 4K rather than a tight bound, deliberately: a tight bound fails on a loaded machine and gets deleted, which is worse than a loose one that still catches the regression that matters. TD-1 is amended rather than joined by a TD-6: on Android the overlay rides the readback that already exists there, roughly doubling that transfer while peaking is on, and TD-1's own "Done when" removes both because both are the same missing capability. Verified: cargo fmt clean; clippy --workspace --all-targets -D warnings green, which also compiles peaking.slint through dr-ui's build.rs; 11 focus GPU tests and 79 baseline dr-gpu tests pass; 511 dr-ui tests pass. Not verified: the cfg(target_os = "android") arm, which the host-target clippy never compiled. 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.
