F1: the Stop button was wired only to useChat.stop() (a local SSE abort the server ignores for a detached run), and dropping isStreaming re-armed observer-polling so the still-running run streamed back into view. Add a client stopRun(chatId) -> POST /ai-chat/stop; in autonomous mode Stop now also calls it (the authoritative stop). A stoppingRun latch suppresses the observer MERGE (observedRow requires !stoppingRun) so the stopped run's newly-persisted partial steps don't re-stream between Stop-press and terminal settle. The latch clears only once this tab is no longer the streamer (!localStreaming) — while streaming, the disabled run query holds the PREVIOUS turn's terminal run in cache, which would otherwise clear the latch early and re-open the flash on turn 2+. Latch releases on stopRun failure (view resumes) and on chat switch. F2: give autonomousRuns a real enable path through the standard settings.ai.* toggle (update-workspace.dto + workspace.service persist/audit + ai-provider-settings switch + client workspace type), mirroring aiDictation. Persists to settings.ai.autonomousRuns — the exact key the controller and ai-chat-window read. F3: correct the pending->running comments (beginRun inserts 'running' directly; 'pending' is a reserved default never written in phase 1).
