+## Basic Moritani Atomics — 29 October 2026
+
+In supported Basic Richese/Moritani tables, a clean shipment or ground move
+that reveals Atomics can offer Semuta after the random excess-card discards.
+The losses, reduced hand limits and Aftermath are committed once before the
+offer; claim or pass resumes the original entry without rerolling. Multiple
+affected players' discards form one private fresh batch. Under the existing
+provisional Semuta policy, only the committed claimant sees eligible faces and
+can take one card discarded by another player. This batching is an online
+timing interpretation, not a publisher ruling. Older pending batches without
+an offer retain their original continuation; Advanced and overlapping or
+special arrival parents remain outside this slice.
+[Runtime cases](../tests/semuta-terror-atomics.test.ts) use a public Basic
+start with staged physical hands, alliance and arrival.
