Constrain the sender label to the message width so long agent names do not wrap above received messages. Keep the line limit opt-in on Button and cover compact chat widths with a real-browser regression.
Native hidden overflow capped the measured content at the preview height, so long messages never offered Show more. Use the native scroll layout mode on the existing View to measure full content while preserving clipping, and store only whether it overflows.
* fix(app): preserve reading position when older turns fold
Item-based history pages can complete and collapse the row at the reading position. Transfer its anchor to the folded turn host so reaching history start does not drain older pages. Also omit reasoning from action summaries and align sender attribution with its message bubble.
* fix(app): preserve the reader when older pages extend tool groups
Resolve grouped calls and folded turns through one presentation-owned row lookup. Keep retained group indexing off the streaming path and verify item-page group replacement against its failing baseline.
* fix(app): preserve message previews when opening turns
Keep the wrapper child structure stable so React does not remount the message fragment when the indent rail appears. Remounting reset preview measurements and briefly removed the fade and Show more control.
* fix(app): separate show less from expanded message text
* fix(client): preserve history loading on older hosts
Whole-turn paging is optional, but requiring its capability blocked existing history reads before any request was sent. Negotiate the paging enhancement at the client boundary while preserving item-based requests for older daemons.
* fix(app): preserve row ownership during late turn updates
Late lifecycle events retagged the newest row even when they updated an earlier call, causing the next update to append a duplicate tool ID. Assign turn membership only to rows written by the event before finalizing unrelated reasoning.

* fix(app): keep autonomous turns distinct and readable
Hidden system prompts merged autonomous work into the previous response and reopened completed turns. Preserve canonical turn boundaries and expose their triggers, while making received messages attributable and expanded turn details readable in one step.
