+**Sapho at Ecological Testing Station — 29 October. Prototyped / Partial.**
+Before either of two station occupants chooses, a holder can discard Sapho to
+change its own position first or last. The original storm source, physical
+storm order and both cumulative choices remain; fresh event and signed receipt
+preserve the selected order. Basic and Advanced real Discovery journeys use a
+staged printed card; separate genuine public Richese/Discovery starts stage
+conserved station pieces and move the original Sapho from the cache. Seven
+related files pass 40 cases, including 12 new cases; type checking, lint and
+the production build pass. The ordering is provisional: an automated current
+occupant may act before another player intervenes. Semuta reaction profiles,
+recovered Sapho replay and deployed acceptance remain open. Two stale Richese
+Nexus guide statements were also corrected against existing runtime evidence.
