The AgentComposerBar refresh button wrapped to a second line on mobile: the status dot had ml-auto (pinned to the far-right edge) and the refresh button followed it in DOM order, overflowing past the edge. Group the dot + refresh into one right-aligned (ml-auto) unit so the refresh stays on the top line. Also add an iconOnly option to CompactPicker and render the Mode (permission) picker icon-only on mobile (shield + chevron, no label; aria-label/title + tap-to-open list still convey the selection) to free row width. Desktop unchanged.
Bundles in-progress working-tree UI work not authored this session (CoderPane ChatInput migration, AgentComposerBar/CoderMessageList/tab-bar/sidebar/pane refinements, provider icons) with this session's changes to the same files: MessageBubble renders a collapsible 'Thinking' block from reasoning_text/reasoning_parts (surfacing ACP agent_thought_chunk + native reasoning), and the DiffPanel approve/reject calls are repointed to the real /api/coder/pending/:id/apply and /reject routes (the old /sessions/:id/pending/:id/approve|reject paths did not exist).
