On Android split view, while the composer has the keyboard, the thread header drops to one line, and the muted subtitle (T3 Code · corex) sat about 2dp above the title's baseline. The Row centred the smaller subtitle against the larger title rather than aligning their text.

Expo UI 58's Row only aligns top, center or bottom, with no baseline option. So the compact title is now one Text with the subtitle as a smaller, muted span. Spans in one paragraph share a baseline. A long title still truncates the subtitle first, as before. The 8dp gap is now two spaces at the subtitle's size.

The sidebar icon and the ✦ in the reported title were already aligned. The icon's centre is within 1px of the title's, both in the report and on the device. The ✦ is a character of the title text itself, so it already shares the title's line. Neither changed.

Scope and approval

A focused fix for an obvious visual bug, reported by a maintainer, under the focused bug-fix exception. It changes one file and only the compact header's text layout; no new behavior or settings.

Verified on a POCO M3 Pro (Android 13) with Smallest width set to 800dp and dev client 2.2.0 (fingerprint fe047aa3). Before is main at dff0b1159b, after is 3f9840959d. Same steps both times: open a thread, focus the composer, capture the header. On the device, the subtitle's text bottom moved from y=141 to y=144, the title's baseline.

Before (top) and after (bottom), 2× crop, red line is the title baseline:

Zoomed: the subtitle sits above the baseline before and on it after:

After, with a long title: the subtitle is cut off first and stays on the same baseline:

vp run check:changed passes.

Not shown: a title containing ✦ on a device (the test data had none), larger tablets, and non-default font sizes.

Explanation

The title names the main change: the Android compact thread header is fixed so the title and subtitle align on one line. It follows the conventional commit format with a clear scope. The changeset matches: AndroidScreenHeader now renders the title and subtitle as nested NativeText spans in one paragraph, so they share a baseline.

Full details: Description check

Explanation

The description is thorough and follows the template. It states the problem (the compact Android thread header subtitle sits about 2dp above the title baseline on Android split view while the composer has the keyboard), the change (the title and subtitle are now spans in one Text, so they share a baseline), and the scope basis (a focused bug-fix exception for an obvious visual bug reported by a maintainer, changing one file). It also gives verification: device model, OS, steps, before/after commit hashes, measured y-coordinates, before/after screenshots, a long-title case, and a note on what was not tested. The Problem section is not under its own heading, and the scope claim relies on an external exception link and a maintainer report rather than an explicit linked approval comment. Those are minor gaps.
