The empty benchmark-report TextEdit held .height(rest(1)) beside
content.height(rest(2)), so it reserved a third of the window at every
launch and pushed the composer two thirds down -- Iris's 11:39 phone
report. It is sized to its content now, capped and scrollable, and sits
above the transcript rather than under the composer.
New log::info! lines for one insets change, one surface_changed, one
renderer build and one surface_destroyed, each with the glyph/atlas
counts, so a phone's adb logcat can answer the app-switch text loss the
emulator cannot reproduce.
Finding 1 (the real crash): Selection::clear() drops rows and anchor,
called from TranscriptScreen::apply's Rebuild arm right before
List::clear() -- push_row re-registers survivors as it rebuilds each row.
Fixes a WeakWidget outliving the row group_tool_runs regrouped away,
which panicked the next long-press anywhere. New apply_tests test builds
a real TranscriptScreen, forces the regroup, and confirms no panic.
Findings 2-5: debug_assert!s on List::place's slot, List::fling and
FlingCalculator's velocity finiteness, VelocityTracker::add_sample's
chronological order, and FrameReport::mark_phase's non-decreasing
start_index. Finding 7: bench_client.rs's battery_line guard restructured
so the empty check can't be separated from its unwraps by a future edit.
Findings 9/10: new List tests pinning tick_fling's per-tick deceleration
and replace_back's evicted-key cleanup with a different key than the
existing tests use. IRIS.md's replace_back/clear/apply entry gained the
side-table-clearing note the Docs finding asked for.
Also records this pass's DragGesture-merge verification in RUST.md (tap
stays vs swipe doesn't, a real fling keeps moving after release, keyboard
cycles confirmed via on_insets_changed) and annotates the two IRIS_TODO.md
phone-report items it targets.

Four fixes from Iris's phone report on the dc01f88 build, plus her same-day
follow-up on swipe-vs-tap:
- android/ime.rs: InputConnection now calls InputMethodManager.updateSelection
after every edit (new update_ime_selection, called from after_input) -- Gboard
was holding keystrokes back with nothing telling it the app's selection/
composing region had moved, which read as "doesn't enter it until I hit
space, doesn't move the caret". New unit tests in widget/text/edit.rs cover
the buffer-level composing/commit/delete/selection operations directly.
- attr.rs: Selector/Selectable rewritten around a shared on_press dispatcher
over PressStart/Pressing/PressEnd instead of click_or_drag(), so a field
that isn't already focused only grants focus (and requests the IME) on a
completed tap -- press and release with no frame past DRAG_SLOP. A drag
is never consumed, so whatever is behind the field still sees it. New
FocusHost::is_focused (both platform impls) and TextEdit::press_origin
back this. Verified on the emulator: dumpsys input_method's mInputShown
stays false after a swipe over the composer, true after a tap.
- iris_core: GlyphAtlas::clear()/Textures::reset(), called together from
android/view.rs's surface_changed exactly when a genuinely new renderer is
built (app-switch, not the keyboard-resize path that already reuses the
renderer) -- both CPU-side caches otherwise kept pointing at the old,
destroyed device's textures. Verified on the emulator: home, reopen, every
glyph still on screen.
- transcript-ui/composer.rs: rebuilt as one widget (unchanged Stack{rect,
span} idiom, capped at ~6 lines via MaxSize + .scrollable(), wrapped in one
Pad whose bottom Composer::set_bottom_inset rewrites in place so the bar
sits on the IME or nav-bar inset with no rebuild -- rebuilding would drop
focus/selection/in-progress text). Wired from bench_client.rs's existing
on_insets_changed.
A second, deeper bug found while verifying the composing fix is NOT fixed
this pass: composed text never becomes visible at all. A new layout_tests.rs
test proves the widget tree's own region math is correct across a keyboard
resize, ruling that out; RUST.md's P0 box has the full writeup and what to
check next (UiRenderState::redraw's single-widget path, or something
force-gles-specific -- this AVD has no Vulkan adapter to rule that out with).
cargo fmt/clippy/test --workspace and cargo ndk clippy all clean.

docs/IRIS.md's 2026-09-06 entry (public API), docs/LAYOUT.md's "Density:
Len::dp" design section, IRIS_TODO.md's density-unit item ticked, and
docs/RUST.md's P0 box gets the investigation: the keyboard-wipe
hypothesis and confirmation, the blur root cause and why the dp unit
turned out to be the same fix, the header cause, and what remains
unverified (an emulator screenshot of the keyboard fix, and Iris's real
phone).

Adds VelocityTracker and a port of AOSP SplineOverScroller's fling curve
(FlingCalculator, cited at the definition) to iris::sense, and wires
List::fling/is_scrolling/cancel_fling/tick_fling through
Selection::drag's release path -- a pan's release now decelerates instead
of stopping dead on the finger lifting, matching IRIS_TODO.md's "swiping
has no momentum" ask. Clamped at the loaded content's start/end and
cancelled by the next touch-down.
Also fixes the scroll jitter DragArbiter's slop release caused: crossing
DRAG_SLOP applied the whole pre-threshold drag (measured from press_start)
in one step, since nothing pans while a gesture might still resolve to a
selection. Now only the excess past DRAG_SLOP is applied on that frame,
the same way Android's own touch handling consumes touch slop rather than
replaying it.
Root-caused by reading DragArbiter's state machine and covered by new
unit tests (fling distance against the closed-form spline result within
1%, cancel-on-touch, start/end clamp, the slop-crossing regression); no
emulator was used this pass, so an on-device trace/feel-check is still
open, and Benchmark v2's four-phase bench_client.rs spec was not
attempted. docs/IRIS.md, docs/IRIS_TODO.md and docs/RUST.md's P0 box
record what's done and what's left.

RUST.md's P0 box gets Iris's first real-phone report (no crash) and the
four defects it found (glyph-wipe-on-first-touch, missing bold glyphs,
text far too small, status-bar inset not applied), what was fixed and
how it was verified on the emulator, and what's still open (item 1's
root cause, and the top-row height anomaly noted in the last commit).
IRIS_TODO.md gets a new "From the phone, 2026-09-06" section for the two
items explicitly deferred to a follow-up agent: no scroll momentum/fling,
and occasional jitter scrolling down.
IRIS.md gets the public-API entry for TextData's bundled fonts/
font_diagnostics, UiRenderNode::new/resize's new window_size parameter,
AndroidUiState::content_scale, AndroidAppState::on_insets_changed, and
iris_core::WgpuErrorLog.

RUST.md's P0 box gets the iris-half account: the fixture, the scroll/stream
mechanism, the report fields, build commands (all clean), packaging (no
cargo xtask apk yet, so a new Gradle release build type on top of cargo
ndk), and the emulator smoke run's report next to Compose's own. Used a
second, differently-named AVD rather than contend with the session already
on this checkout's own emulator.
DECISIONS.md's P0 entry gets a matching summary bullet. IRIS.md records
AndroidAppState::platform_ready. IRIS_TODO.md notes the one gap found:
no read-only selectable text primitive, so the bench report's TextEdit
picks up a keyboard on tap it has nothing to type into.

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.
