- lib/attention.ts: pure snapshot diff (Major opened, severity escalated,
pursuit path gained a stop, priority keyword in a new transcript) with a
silent baseline on page open; calls baseline separately on their first
non-empty snapshot. Diffed over all active incidents so widening a filter
is never "new"; emitted, laned and pulsed only for the FILTERED view.
- components/live/NewLane.tsx: "NEW · last 15 min" overlay above the rail
(desktop) / compact chip (mobile), Gate A notice included.
- components/live/AttentionControls.tsx: opt-in Web Audio tone (enabling
click unlocks audio) and Web Notifications while the tab is hidden, body
carries the machine-output notice; prefs + keywords in localStorage.
- LiveView wires it and passes pulseIncidentIds to MapView (2 min pulse).
- useIncidents: useActiveIncidentsState exposes a loaded flag (first
server snapshot) so the baseline never sees an empty pre-load list.
- MachineOutputNotice exports MACHINE_OUTPUT_NOTICE_TEXT (same wording).
