+**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.

+**Prototyped / Partial.** Before either of two original occupants chooses,
+an eligible holder can discard Juice of Sapho to change its own choice to
+first or last. The original physical storm order, source and token are retained;
+both occupants still adjust the cumulative distance once. The reordered frame
+has a new event and a signed record of the original order. Unchanged frames
+retain their original signatures. A position already held, a completed choice,
+and another use after a recovered Sapho are not offered in this first version.
+Semuta reaction profiles are guarded until that separate discard continuation
+is connected. The ordering is a provisional online interpretation of Sapho's
+printed first/last effect; no combined publisher clarification is claimed.
+The current occupant may make its choice before the other occupant plays Sapho,
+including when an automated seat acts first. There is no neutral pre-choice
+priority window yet, so first-position intervention is not guaranteed against
+an automatically acting current occupant.

+
+The printed Juice of Sapho allows first or last in an ordered action. In a
+two-occupant Ecological Testing Station queue, an occupant can provisionally
+change its position before either choice. Both original adjustments still
+apply once to the original revealed storm source; physical storm order is not
+changed. Already-held positions, completed choices and a second recovered
+Sapho use remain outside this first version. Semuta reaction profiles remain
+guarded until their discard continuation is connected. This is an online
+priority interpretation, not an explicit combined publisher ruling.
