Iris: "the organization of the rust rewrite is a mess right now... there shouldn't be anything related to the app inside of iris. Iris is supposed to be the UI framework alone." And, on the crate count: "I'm confused why the app only code needs more than one crate though." Nine cargo workspaces become three, and the port's project code -- which sat in five places, four of them inside the framework -- becomes one crate, `ai-app`, in `app-rust/`: client-core -> app-rust/src/client iris/transcript-ui -> app-rust/src/ui iris/transcript-fixture -> app-rust/src/ui/fixture.rs + tests/ + touch/ iris/desktop-app -> app-rust/src/desktop + src/bin_desktop.rs iris/android-app -> app-rust/src/android + android-project/ android-shell -> app-rust/src/shell iris/ keeps core, macro, the iris crate, tabs-ui and rig-input, and now mentions no session, transcript, setup or server anywhere. Only two of the old splits had a reason that survived reading. event-model stays a crate at the repo root because server/ depends on it too, so a crate is what makes the backend and the app agree by construction. The two Android .so names looked like a hard constraint -- a package produces one library artifact -- until P2 turned out to already plan merging those two Android apps into one; both faces now come out of libai_app.so, picked apart by features so `--no-default-features --features shell` keeps wgpu, parley and iris out of the Compose app's APK. docs/RUST.md's "One app crate" has the rest, including what each remaining feature is for. DECISIONS.md and SUBAGENTS.md move into docs/ with everything else. Verified: ./run-tests.sh and `cd iris && cargo test` green, clippy and fmt clean in all five workspaces, `cargo ndk -t x86_64` links libai_app.so, build-apk.sh produces an APK that installs and launches on this checkout's emulator (Gl ... virgl, as expected), and the phone-sized headless screenshot renders the transcript unchanged.

iris
My experimental attempt at a rust ui library (also my first ui library).
It's currently designed around using retained data structures (widgets), rather than diffing generated trees from data like xilem or iced. This is an experiment and I'm not sure if it's a good idea or not.
Examples are in examples, eg. cargo run --example tabs.
Goals, in general order:
- does what I want it to (text, images, video, animations)
- very easy to use ignoring ergonomic ref counting
- reasonably fast / efficient (a lot faster than electron, save battery life, try to beat iced and xilem)
dev details
not targeting web rn cause wanna use actual nice gpu features & entire point of this is to make desktop apps / not need a web browser
general ideas trynna use rn / experiment with:
- retained mode
- specifically designed around wgpu so there's no translation
- postfix functions for most things to prevent unreadable indentation (going very well)
- events can be done directly where you draw the widgets
- almost no macros in user code & actual LSP typechecking (variadic generics if you can hear me please save us)
- relative anchor + absolute offset coord system (+ "rest" / leftover during widget layout)
- single threaded ui & pass context around to make non async usage straightforward (pretty unsure about this)
- widgets store outside of the actual rendering so they can be moved around and swapped easily (unsure about this but seems to work good for now)
under heavy initial development so not gonna try to explain status, maybe check TODO for that; sizable chance it gets a rewrite once I know everything I need and what seems to work best
it's called iris because it's the structure around what you actually want to display and colorful
