The claim that hydration-as-a-borrow makes peak disk the working set rather than the library was so far an argument. `--example vfs_cycle` runs it: 100 photographs of 25 MB, 90 dehydrated, a pass over all of them through the real engine. Peak 275 MB — the resting set plus one photograph — against 2,500 MB had the pass simply fetched everything. Back to 250 MB afterwards, and all ten files the user already kept still there, which is the half of the contract that matters more. Recorded in docs/storage.md §6.3 and ARCH §9.0a, because a bound argued from a number nobody measured is one that gets quietly lost.
DarkRoom
A cross-platform, non-destructive RAW photo editor for Linux and Android.
Status: early. v0.1 is a remote library viewer — see docs/milestone-v0.1.md.
Documentation

| requirements.md | What the software must do — 122 numbered requirements |
| architecture.md | How it is built — crates, GPU pipeline, data model, sync |

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.
