 The explicit `semuta` development profile starts a fresh Richese roster
 without opening ordinary expansion starts. It now interrupts **one public
 ordinary-card discard, the used Box after a completed paid Nullentropy
-search, or an Ornithopter retired by ending movement early**, provided
-the parent transaction is clean, with a neutral fresh-discard opportunity

-already committed movement and physical escrow remain intact; a claim
-or all-seat decline advances the saved movement queue exactly once.
-Each seat can Continue; only the canonical holder with a free hand slot
-and a card discarded by another player can commit. The sole eligible
-fresh card transfers automatically in the same accepted action, then
-Semuta goes to the normal discard pile. The saved ordinary effect or
-Box parent resumes once; passing by every seat preserves the original
-discard and effect. No face from an undisclosed event is projected
-before commitment. Owner-only multi-candidate selection support exists
-in the reaction component and bot adapter, but no multi-discard

 This neutral all-seat acknowledgement is a conservative **application
 policy**, not a newly discovered publisher timing rule. The explicit
 free-slot requirement is a provisional safety guard, not the printed
 resolution of full-hand take-before-discard. Auction, CHOAM market,
 pending gifts, competing responses, completed Ornithopter flights with
-arrival follow-up and other typed discard producers retain their existing
-automatic continuation; Semuta cannot claim those events yet. The
-completed Box's selected search card stays private and its paid shuffle
-is not repeated when another seat takes the used Box. No source ruling
-is inferred from this omission. The

+The completed Box's selected search card stays private and its paid

 separate [reaction privacy audit](SEMUTA_PRIVACY_REVIEW.md) explains why
 auto-closing only when nobody secretly holds the card would leak
 possession. The main game and public expansion gates remain closed.
