RUST.md's "Three test layers" section rewritten in place with what was built: the `cargo test -p transcript-fixture` command and the five assertions with the mutation that fails each, the `run-headless.sh --phone [--replay …]` commands and the 15s/18s they take, and a paragraph on what still cannot be answered below layer 3 (anything about pixels, any frame time, anything JNI). Also the two traps that cost time -- `swaymsg seat - cursor` reaching nothing on a compositor with no input devices, and a leftover window tiling beside the new one so a screenshot looks like a duplicated-primitive bug. IRIS.md gains the public surface: `iris::harness`, `TouchScript`, `List::fling_velocity`, the fling's clock, and the desktop backend's move to physical-pixel layout with `content_scale`/`IRIS_SCALE`.
