Fire Curtain / Egress Collision

This event is the entry surface between recorded pressure and the interlock review. It makes two current safety commands visible at the same moment: F2 is ready to descend for containment, and aisle B must remain open because its crossing window is occupied.

The event records collision, not fault. The empty-house drop proof remains valid in its own conditions, and the occupied aisle remains a valid present veto. The event neither chooses a branch nor grants the sponsor cue physical authority.

Once-only and authority rules

The event opens only once and must not appear from the seven cards alone. It requires the player-recorded four-pressure intake. Resolving it may open storyteller.rite.fire_curtain_egress_interlock_review.v1; it may not resolve the interlock, clear aisle B, silence Usher Lin, or arm the false default.
