Run user shell commands concurrently with model execution, retain their output in one shell entry, and admit non-waking completion messages. Share result capture and notification formatting across shell callers.
Buffer bulk history privately and publish once with a bounded head window. Preserve pending anchor compensation while ensuring newer navigation cancels obsolete Home work. Add atomic-loading and real-App navigation regressions.
Merge session status changes received during activity hydration and ignore superseded reconnect responses. Cover terminal events, starts, deletion, and overlapping connections so idle sessions do not regain stale TUI spinners.
