Three places, because the finding has three audiences. The display spec's §1 table said FR-DSP-3 was unmeasured and FR-DSP-5 untagged. Both are now false, and §2's decision rule has fired. The body of §2 is left as written with the verdict quoted above it: a plan overtaken by its own evidence reads better in order than quietly edited into agreement with the outcome. TD-4 is the stage that misses the budget. Clarity's kernel is a fraction of the frame, so it reaches a 52-pixel radius at 4K and costs 34 ms — seven times the entire fused chain, for one slider. It is debt rather than a bug because the detail stage cannot yet write a target smaller than it reads, which `local_contrast`'s own documentation has said since it was written. The entry says plainly that tiles are the wrong tool for it, since that is exactly the conclusion a reader arriving from ARCH §5.3 would otherwise draw. TD-5 is the one nobody was looking for: composing the fused shader costs 2.8–5.2 ms of CPU per frame on a full chain, on the UI thread, which at 1920x1200 is more than the dispatch it precedes. The source depends only on the graph's structure — what `structure_hash` already identifies and what does not move during a drag — so the fix is the cache `AdjustPass` already keeps for compiled pipelines, one level up.

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.
