 The remaining order is winner casualties, applicable Ixian substitution, optional winner cards, Moritani cleanup, CHOAM support income, tech transfer, Harkonnen capture, Auditor, Face Dance and the next battle/phase. Winner and Moritani discards are distinct later batches. Empty batches create no event. Moritani's consumed retention receipt preserves played and kept identities without requiring discarded cards to remain in hand. Older cleanup decisions without a resolved receipt can establish one from their existing authenticated parent; a mismatching existing receipt is rejected.
 
+11 October 2026 Semuta update: the explicit development preview admits mandatory
+and winner-card batches with the native Advanced Harkonnen capture still pending.
+Claim or all-seat decline retires the discard receipt before the original
+casualties, cleanup and capture suffix. The capture offer samples no captive
+until its original response finishes. Other pending reward exclusions are
+unchanged; this does not certify complete Semuta or expansion combinations.

 Sequence retirement precedes the remaining work. Ordinary public actions still drain these saved steps automatically. Test-only observation of unchanged private production dispatch captures real intermediate frames; this is not a public Semuta reaction window.

+## 11 October 2026 — Semuta before native Advanced Harkonnen capture
+
+The resolved battle and winner-cleanup receipts already validate the original
+pending capture's winner, loser and territory. Removing only `pendingCapture`
+from the reaction exclusion admits both discard batches without changing the
+capture handler, random selection or aftermath ordering. Other pending reward
+exclusions remain intact.
+
+The real Advanced Richese/Harkonnen fixture now covers mandatory loser disposal,
+winner disposal, claim/pass, unchanged resources and pending capture, retired
+events, card conservation and one retained captive. It fails before the guard
+change and passes after. The fixture also declines the existing Atreides
+full-plan inspection before shared readiness; no preparation bypass was added.
+Types/lint and 97 affected cases across eight files pass.
+
+Thirty-six isolated engine scenarios cover both producers with claim, all-seat
+pass and all four legal AI profiles, followed by capture decline, retention or
+execution. Each reaches Collection with zero or one captive as appropriate;
+execution gains exactly two spice against the same decline suffix. An initial
+probe wrongly attributed automatic Collection income to capture; its corrected
+comparison uses the complete same-phase baseline.
+
+Real production GameTable controls at 390px claim the winner's Stunner, resume
+Capture a leader, inspect the captive and retain exactly one before Collection,
+without horizontal overflow. The QA adapter only switched seats and mounted the
+real table against an isolated memory-only engine; it touched no saved store.
+All temporary scripts, server and browser tab are removed/stopped. The first
+compiler pass stopped on an unused temporary fixture helper; after scaffold
+removal, the frozen implementation check passed.
