 //
 // Why this exists: eleven floor systems shipped in one day and the only bot
 // nights we had were doorgirl nights. An untested economy is a guess.
+//
+// WHAT THIS DOES NOT MODEL, so nobody reads a green suite as wider cover than
+// it is: the floor's escalation layer (maggot ripening -> radio pressure ->
+// deferred heat), fights, hazards, the glassie run and the DJ booth. The
+// 2026-07-22 review found a real bug in exactly that seam — watering someone
+// from behind the bar left them ticking as an unhandled maggot — and this
+// harness would not have caught it. Extend here when that layer needs bands.
