Sessions were sorted and previewed using the timestamp and text of the first message in the JSONL file, so a session that started hours ago but is still being actively written never bubbled to the top, and the list showed the opening prompt instead of what's actually happening now. - Sort and "time ago" now use the file's mtime (last write), not the first message's timestamp. - The list's message preview is now the most recent user message (read backwards from the end of the file, doubling the read window until found, so multi-hundred-MB session files stay cheap). - Each session row gains a second, indented line showing the last line of the most recent assistant reply -- the part of the response most likely to carry a question or next step. - The TUI now rescans ~/.claude/projects/ every 3s while browsing (a full rescan is ~23ms for ~100 sessions), so sessions written to by another process show up live without relaunching. Selection and scroll position are preserved across a refresh by session id. List rendering, scrolling and mouse click handling were reworked to support the resulting variable row heights (1 or 2 lines per session).

Populate tail previews for content-search sessions.
When search_file_with_metadata creates the fallback Session, it sets last_assistant_line to an empty string. DisplaySource::Content uses this session, and the list renderer therefore omits the assistant preview. The content snippet replaces first_message in the primary row, so the row does not show an old user message.
Use the same tail-preview extraction as src/discovery.rs.

Clamp selection when a header is selected.
A selected header sets selected_id to None. If refresh produces a shorter list, selected remains outside the new bounds. The TUI then renders no selected row until another navigation action corrects the index.
Clamp selected after every rebuild, including the no-ID path.

Reconcile content results during refresh.
A completed content search leaves content_results unchanged. The refresh replaces sessions and then rebuilds display items from the stale results. A removed session can remain visible as DisplaySource::Content, and changed sessions can retain stale snippets.
Prune and refresh these results by session ID, or restart the active content search after rebuilding the index.
