An ordinary weapon becoming ready with a valid target is a proposed external equipment event and starts one causal wave. Readiness advances only through stated world time; rig output cannot ready the controller again or mint a launch event. Descendants retain the launch wave. Assembly labels manual specials: a chosen Capacitor release, aimed shove or directional Barrier starts a manual external wave. Dynamo and other reactive parts remain automatic only on inspected triggers.

- A **flanker** uses a visible connected side approach when the direct lane is obstructed. It never teleports or knows an unseen route, making facing matter without making enemy steering the experiment.

- A **caller** visibly braces and warns. If completed, it calls eligible adjacent groups. Displacement, obstruction or defeat prevents the call. At the jammed door, the caller and connected entrance are cued before cutting begins.

The lit run ending at the vestibule entrance is one readable boundary. Clearing its visible crowd removes that encounter population for the expedition, not the distinct door caller, an active source or unused adjacent groups. A living enemy outside may later walk or investigate through a connected route with sight, sound or door cues. That is ordinary movement, not success-triggered replacement.

A decisive rig can decide an encounter. Cascade clearing the run defeats that crowd; a quiet return stays clear unless a separately cued living enemy approaches. The wider door area is quiet only after its caller/source, present enemies and travelling groups are resolved, with no unused eligible groups behind an active source. Counterwall can preserve completed door stages; Cycler can spend cargo to open a temporary lane, not a solid lasting barrier. None causes replacement elites, invisible escalation or reduced reward. Victory buys access, time, oxygen margin and discovery opportunity.
