Mobile Bestie used a special flat timeline that hid reply threads. It
now opens the normal DM screen, matching desktop’s pinned Bestie
(block/buzz-app#1935), with existing threads, reply actions, and
top-level sending in the same conversation.
Thread-scoped agent typing in DMs stays beneath its originating message.
Working avatars and mobile’s bouncing dots share a compact neutral
container, matching desktop’s subtle activity control. The elbow is
visible from the start, with the working container already at the final
thread-footer position. For a single-agent reply, the same avatar stays
mounted while the container and dots fade out over 200 ms, the avatar
slides into its summary position, and the reply count fades/scales in
from 95%. The elbow stays fixed. Reduced motion switches immediately.
The avatar-to-dots gap is 4 points. Reply text uses its natural line
height so its glyphs center on the avatar and elbow rather than drawing
at the top of the footer. Multi-participant summaries retain their
grouped layout. The accessible View thread action, reaction placement,
and final reply-footer position are preserved.
Validation:
- The final commit (`c6fef5d80`) passed full analysis, 4,220 Flutter
tests (40 skipped), 4 push-configuration tests, and 27 crypto tests.
- Container alignment checks pass in both directions, including avatar
continuity, intermediate fade and final geometry, reduced motion, and
thread actions. Glyph-box alignment is checked against the avatar
center. An additional regression covers a reply arriving before typing
stops and work restarting mid-transition.
- Updated DM journeys cover opening Bestie, existing threads, threaded
and top-level sending, swipe-to-reply, and absence of duplicate main-row
thread typing.
- Installed the final product source (`c6fef5d80`) in place on Pixel 10
and iPhone Air previews. The iPhone uses a release-mode preview so it
launches from the home screen; saved Kenny Lopez / Starry Night
conversation verified after install. Pixel retains Testing Agent
Sessions. The pending/midpoint/completed handoff was rendered in widget
checks, and the corrected reply-label alignment was verified on the
Pixel against the same messages before and after; human acceptance of
this final animation remains pending.
- Mandatory push hooks passed, including file-size and branch checks. A
rendered widget preview verifies the container and elbow; live
acceptance remains pending.
Self-review found no blockers in the changed paths. Review status is
preserved.
