+## Live alarm watch-list replacement
+
+An auto-mode `SubscribeAlarms` with `fallback_enabled = true` always builds a
+`FailoverAlarmConsumer`, even when initial discovery supplied no targets. The
+handler retains the subscription expression so `UpdateAlarmWatchList` can build
+and subscribe a new subtag consumer entirely on the session STA. The failover
+consumer attaches the replacement's transition callback before swapping the
+standby reference, then detaches and disposes the old standby. If construction,
+subscription, or attachment fails, it disposes the replacement and preserves
+the old standby. The active-provider selector is never reset, so primary mode
+stays primary and subtag mode immediately delegates to the new standby.
