 ## 30 September 2026 — bounded clean-discard runtime
 
 The explicit `semuta` development profile starts a fresh Richese roster
-without opening ordinary expansion starts. It interrupts **one public
-ordinary-card discard, the used Box after a paid Nullentropy search,
-either retirement of a played Ornithopter in a clean flight, the used
-Distrans after a private transfer, a final definite Truthtrance,
-movement-order Juice of Sapho, mandatory winning-card cleanup, or a
-later winner-selected battle-card batch without pending rewards**,
-provided the parent transaction is clean. Every seat sees a neutral
-fresh-discard opportunity regardless
-of hidden Semuta possession. An early-ended Ornithopter advances its
-saved movement queue; a completed flight has committed its forces
-and resumes its one arrival only without BG, Ecaz or Moritani entry
-reactions. Distrans's gift stays private with its recipient. The
-Truthtrance answer/history and Sapho first/last queue are bound.
-Mandatory winning cards form one public fresh batch after the
-previous loser cleanup, and any later optional winner selection is a
-separate batch. Neither a Semuta claim nor all-seat decline replays
-casualties or re-discards an already claimed card.

 Each seat can Continue; only the canonical holder with a free hand
 slot and a card discarded by another player can commit. A sole
 eligible fresh card transfers automatically in that same action.
