+The first direct information-to-help path is complete. At shared activity, a
+performer or direct witness now discusses the active need's exact trigger before
+newer unrelated facts. The original event and first-source provenance remain
+authoritative and one-hop. A newly informed trusted, supplied villager is then
+re-derived and autonomously responds through ordinary action selection. A
