The 07-21 morning outage (loop booted post-EOD on the 20th, survived
midnight, silently blocked every entry while signals went READY) had zero
UI surface. New query_loop_session projection parses the live session id's
embedded date; a red banner fires when it isn't today's — the exact day-2
poison signature — telling the operator to restart the loop. Armed
Triggers rows now also show rvol_tod (the arming signal since 5597250)
next to legacy rvol.
