Closes #10840

Problem

On mobile, when you scroll up while a turn is running, the floating control shows the centered "Working 1m 12s" pill and a small scroll-to-end circle to its right. Only that circle scrolls. Tapping the bigger pill in the middle does nothing, which makes getting back to the end awkward, especially with your left thumb.

Fix

When a passive status (Working, Compacting, Syncing, Stopping, a goal, Preparing) and scroll-to-end are both showing, the status becomes one pill with a chevron, and tapping anywhere on it scrolls to the end. The separate circle hides, so the pill stays centered instead of sliding left.

Following the triage notes on the issue:

• Combined only when a non-interactive status and showScrollToEnd are both on. The pill's onPress is onScrollToEnd, so screen-reader activation works too.
• Scroll-only keeps the existing circle. Status-only keeps passing touches through to the feed.
• The connection pill keeps its reconnect tap, and child-input and background statuses keep theirs. Queue, agents, preview, and action segments such as Force stop keep their own buttons next to the combined pill.
• Same layout on iOS glass and on the Android/fallback pill, because both render the shared capsule content.
• The combined pill's accessibility label is "Scroll to end".

One file changed: apps/mobile/src/features/threads/floating-working-control.tsx.

Verification

Setup: isolated dev server (vp run dev --home-dir <checkout>/.t3), Android emulator (Pixel 9 Pro Fold image at a phone-sized 1080×2424 display), and iPhone 18 Pro simulator (iOS 27, Liquid Glass), both on dev clients built for this checkout. To keep a turn in "Working" without a paid model, I added a local ACP provider instance to the isolated settings that runs the repo's apps/server/scripts/acp-mock-agent.ts with T3_ACP_HANG_PROMPT_FOREVER=1, then started a thread with a 60-line prompt so the feed scrolls.

For each platform, before is main (e2bb9e6) and after is this branch. Steps: scroll up while Working, tap the Working pill, then tap the chevron.

	Before (main)	After (this PR)
Android	Tapping "Working" does nothing; the feed stays on line 32. Only the circle scrolls.	Tapping the pill's left edge scrolls to the end.
iOS	Same: the pill does nothing, only the circle scrolls.	Same: tapping the left edge scrolls to the end.

Android

Scrolled up	Tap "Working"	Tap chevron
After: scrolled up	After: tap the pill's left edge

States that must not change

Reconnect stays its own button (Android)	Stopping + Force stop stay separate (iOS)	Scroll-only circle (Android)	Scroll-only circle (iOS)

• Reconnect: I dropped the emulator's connection to the server while scrolled up. "Failed to connect. Retrying…" stayed its own button with the circle beside it, and tapping it reconnected without scrolling. Afterwards the combined Working pill came back. (recording)
• Stop / Force stop: "Not responding to Stop ⌄" scrolls, and Force stop is a separate button. In the iOS accessibility tree they are two non-overlapping buttons: "Scroll to end" at x 49–265 and "Force stop the agent" at x 266–352. One tap on Force stop opened its confirm dialog on both platforms.
• Status-only: at the end of the feed, the plain "Working" pill comes back and still passes touches through. This shows in the "after tap" captures above.
• Accessibility: the combined pill is announced as the "Scroll to end" button. The hidden circle keeps its existing disabled state.

Full recordings: Android before / after, iOS before / after.

vp run check:changed passes: format, lint, knip, typecheck, and React Compiler. No test was added. The change is layout and press wiring, and the recordings cover it.

Not checked

• Physical devices and dark mode; I only used the simulator and emulator, in light mode.
• The reconnect state on iOS. The connection pill path is unchanged and shared, and I checked it on Android.
• Android's reconnect and stop captures came from a build before I changed the chevron's color class from foreground to accent-icon, which fixed a blue chevron on iOS. The behavior is identical, and the final Android before/after above were recorded on the final code.

Approvability

Verdict: Approved at 1290a6a

Macroscope's review found this PR approvable — Passive status pills now scroll to the end when tapped, with an inline chevron replacing the separate scroll button. The change reuses existing scrolling behavior and is limited to mobile UI interaction and presentation.

Walkthrough

The mobile floating working control can use a passive status capsule as the scroll-to-end target. The separate scroll circle and its interaction, accessibility, and animation states now follow whether the circle is visible.

Changes: Mobile scroll control

Layer / File(s)	Summary
Status capsule and scroll-circle behavior apps/mobile/src/features/threads/floating-working-control.tsx	When scrolling is available and the status is passive, the capsule becomes an accessible “Scroll to end” target with a down chevron. The separate circle’s visibility controls its interaction and accessibility states, and the separation animation follows that visibility.

Merge Risk: Low · up to f1185

The pill scrolls to the end, but its status may be unavailable to VoiceOver while scrolled up. The selection logic also needs regression coverage. The accessibility limitation has been accepted for this change.

Explanation

[ #10840 ] The passive Working status becomes a single scroll-to-end button with a chevron. Its onPress calls onScrollToEnd, and the separate circle hides. The shared capsule supports the glass and fallback layouts. The issue does not specify an automated test requirement; no test was added.

Explanation

[ #10840 ] The whole-PR diff changes only floating-working-control.tsx. The changes support the combined button, its accessibility, and circle visibility. The extension status changes shown in the incremental diff already exist at the merge base; this PR does not introduce them.
