+**Prototyped / Partial.** A public event that establishes the actual unique
+Duke disc clears the uncertainty receipt, including when an older game lacks
+one. Supported events are a revealed ordinary Duke battle; a named paid, Ghola or
+Tleilaxu Ambassador revival; Ecaz Nexus Cunning or occupied-Ecaz grant; a
+public Moritani acquisition or Tanks resolution; and a named Residual Poison
+or Terror assassination death. Canceled, declined or unrelated actions do not
+clear it. A subsequent Harkonnen capture that could have included Duke records
+new uncertainty. The existing eligibility and custody checks still apply.
+
+An Advanced Harkonnen game with clear public history can now also use the
+provisional same-recipient conversion from another temporary tenure. A current
+ordinary Ecaz Ambassador tenure cannot be redundantly renewed. The public
+history safeguard remains uniform when the marker is uncertain or absent.

+Twelve related files pass 87 cases. The real battle fixture verifies a later
