Splits each frame sample at queue.submit into redraw-to-submit (iris's own CPU work) and submit-to-after-present (driver/GPU wait), so RUST.md's I5 "where does iris's frame time go" question can be answered with a number per half instead of a single total. Adds a force-gles Cargo feature that switches the Android wgpu::Instance from Backends::PRIMARY to Backends::GL at compile time (no runtime env-var path exists into an already-launched Android process on this machine), for isolating SwiftShader-Vulkan vs. GLES/virgl as the software-mode gap's cause. app/iris-scroll.sh extracts transcript-bench.sh's exact 24-swipe/6-cycle gesture loop for iris's own demo app, which transcript-bench.sh cannot drive directly since it opens a session through the Compose app's own UI. Verification (this pass, on a disk-pressure-limited host running low on space): cargo fmt --all clean, no diff. cargo clippy --workspace --all-targets: no warnings from this diff (pre-existing future-incompat notices from wgpu/winit/naga only). cargo test --workspace and cargo ndk for iris-android-app --features transcript-screen were verified clean by the previous pass on this identical diff (fmt/clippy/test/ndk all clean, per that pass's own report); not re-run here because the host's disk was 93% full and a concurrent ai-server rebuild (stable toolchain moved to 1.98.1, rebuilding aws-lc-sys from scratch) had driven I/O pressure to ~60%, so a repeat cargo test --workspace sat 50+ minutes doing no useful work and was stopped rather than left to make the disk situation worse.

# RUST.md's I5 "Where iris's frame time goes" pass (2026-09-05). The same

# 24-swipe/6-cycle loop as transcript-bench.sh's, extracted for iris's own
|
|
# demo app -- transcript-bench.sh itself is Compose-specific (opens by
|
|
# session title through the Compose app's own UI) and cannot be called
|
|
# directly against dev.iris.android.demo.

# MUST be run from inside this checkout (not /tmp): ui-trace/adb pick which

# emulator to target from the current directory's basename (the
|
|
# per-checkout-AVD rule), and a previous pass lost two attempts to a `cd`
|
|
# into /tmp that made this resolve to a nonexistent "tmp" checkout.
