+## Advanced CHOAM and Residual Poison discards — 29 October 2026

+**Prototyped / Partial.** The public Advanced Richese and classic/CHOAM preview
+also offers Semuta after a completed CHOAM sale, supported printed Kulon,
+La La La, Baliset, Trip to Gamont or Jubba Cloak costs, and a clean pre-leader
+Residual Poison. Claim or pass retains the original payment, restriction,
+movement, force return, storm protection or single leader death and continuation.
+Private Nexus substitutions and other parents remain outside this slice.
+
+The [CHOAM journeys](../tests/semuta-advanced-public-choam.test.ts) and
+[Residual Poison journeys](../tests/semuta-advanced-public-residual.test.ts)
+start public Advanced games and stage conserved cards and relevant phase or
+battle state, then exercise native actions; they do not certify a full game.
