adapter.request_device asked for Limits::default(), which requests
desktop-tier compute-shader limits unconditionally even though nothing in
iris/iris-core creates a ComputePipeline or writes a @compute stage. That
crashed device creation outright on a downlevel GL adapter reporting
OpenGL ES 3.0 (no compute at all) -- the Android emulator's
EMU_GPU=software/force-gles path, and any real GLES-3.0-only device.
New iris_core::device_limits(), shared by both platform backends, zeros
exactly the six max_compute_* fields rather than switching to a downlevel
Limits preset -- downlevel_webgl2_defaults() also zeros
max_storage_buffers_per_shader_stage, which shader.wgsl's vertex stage
needs. rigs/gpu-probe's own mirrored limits were updated to match.
Not verified against the actual SwiftShader-ES-3.0 crash on-device this
pass: the cold boot needed would have force-restarted this checkout's
emulator while another session had its own app running on it.

Root-caused via temporary logcat tracing (touch events, DragArbiter state,
Selection::drag dispatch), reproduced against a real sandbox session: a
gesture's ACTION_DOWN can land on a row's own padding/gap or its header,
which CursorSense has no sensor over, so the widget that ends up handling
the gesture only ever sees Pressing frames and DragArbiter never gets
press_start -- leaving it stuck in Idle (answers Undecided forever) for the
rest of that gesture. Not the previously-suspected coalesced first
ACTION_MOVE, which is now ruled out.
DragArbiter::is_idle() lets Selection::drag notice a Pressing frame with
no matching press_start and recover the press there instead. Four new unit
tests, one of which fails on the pre-fix code.

Adds "The port, in order (decided 2026-09-05)" to RUST.md: seven ordered
steps building the app on iris now that the framework is decided, each
naming the Kotlin files it replaces, the client-core pieces it needs
(and which are not yet covered and must be ported first), the missing
iris widgets it needs (recorded in IRIS_TODO.md's new "Build (for the
port)" section), and a pass condition a later agent can run. Ordered by
risk to the daily-use path: session screen parity, then the shell merge
and a real phone install, then root tabs, the file explorer,
settings/enrolment, desktop parity, and the cutover itself.
Crate-shape decision recorded in DECISIONS.md: one UI crate, app-ui,
grown out of transcript-ui rather than started beside it, with
desktop-app/android-app as thin entry points over it and platform-only
code staying in the E3/E5 Java shell.
Updates RUST.md's "Where things stand" and "For the next agent" to point
at P1 rather than the now-closed framework decision.

FrameReport gave a real, measured on-device number (frames=34,
janky%=61.76, p50=26.5ms p90=48.0ms p99=98.1ms worst=98.1ms) and
long-press-then-drag-to-select is now confirmed on-device (logcat plus a
screenshot of the highlighted selection). Neither closes I5's box to [x]
yet: the frame number is real but not the clean single 24-swipe loop
comparable to Compose's, because gestures against this checkout's
EMU_GPU=software emulator intermittently delivered zero touch input this
session -- a new, separately named finding (candidate cause: the
emulator's own software rasterisation measured at ~78% of a CPU core
continuously), not yet root-caused. DECISIONS.md's DEFERRED item is
updated with these numbers rather than a decision made here.

I5's transcript screen now runs on-device against a real ai-server on
iris-android-app's new transcript-screen feature (extends I2's shell
rather than a third one), with real scrolling, real touch-drag panning
and tap-by-name accessibility all confirmed by screenshot/log evidence.
I4's own emulator-side check (tap-by-name on the tabs demo) closed the
same session, so its box ticks [x] now.
Still [~], not [x]: the render-time number RUST.md's recommendation
wants for iris couldn't be produced this pass, for a precise and
recorded reason rather than a vague one -- dumpsys gfxinfo cannot see a
SurfaceView's own GPU-drawn frames at all (0 frames reported across a
gesture loop that visibly scrolled), and a SurfaceFlinger --latency
fallback gave no per-frame history either on this Android version. The
Compose side of the same loop did produce a real number under identical
conditions (8.96% janky, 99th percentile 150ms), so this is now a
one-sided number rather than a missing one on both sides.
Also found and recorded: the AVD's saved snapshot carries a GPU config
across restarts, so switching between the documented Vulkan boot
recipes needs a cold boot (clearing snapshots/) that the emu wrapper
does not force -- cost three different-looking crashes before the
pattern was the snapshot, not the code.
DECISIONS.md's DEFERRED item is updated with the numbers Iris needs to
weigh the iris-vs-Masonry call; the call itself stays hers.
