 # Mandatory advisor conversions
 
+## Native Fremen worm ride — 29 October 2026
+
+**Prototyped / Partial.** When an accepted native Fremen worm ride leaves
+Bene Gesserit advisors alone at the origin, the ride and any Sandmaster
+collection finish first. The existing mandatory conversion response then
+allows or prevents the flip before the original destination intrusion and
+entry reactions. Afterward the original remaining worm queue continues once;
+no force is moved or spice collected again. A partial ride leaving another
+faction present does not open this response.
+
+The selected timing combines the supplied Advanced physical pages 17 and 28 E
+with the existing worm sequence; it is a provisional online ordering. A
+prevented group retains the existing continuously-alone hold. Fremen's special
+Karama to summon another worm waits for this conversion to finish; its nested
+losses and altered worm queue need a separate continuation. Nexus Cunning,
+Great Maker and unrelated special arrivals also need separate source contracts.
+The native tests use genuine Advanced setup with explicitly staged ride and
+conserved force positions; the Sandmaster cases use a genuine Skills setup and
+staged board and card custody. Complete faction, mode and deployed acceptance
+remain open.

+**Advanced advisor conversion after native worm rides — 29 October.
+Prototyped / Partial.** A Fremen ride that leaves Bene Gesserit advisors alone
+opens the native conversion/Karama response before destination reactions and
+the remaining worm queue. The ride and any Sandmaster collection stay
+committed; allow or prevention resumes the original arrival once. Genuine
+Advanced setup with staged conserved ride positions covers partial rides,
+destination intrusion, the native counter, controls and all four legal bot
+profiles. Two Skills cases cover actual Sandmaster collection. Fourteen related
+files pass 156 cases, including 14 new cases; type checking, lint and the
+production build pass. Fremen's special Karama to summon another worm waits
+until this conversion resolves; Nexus Cunning, Great Maker and other special
+arrivals remain open. The timing is provisional and deployed acceptance is
+unverified. [Scope](ADVISOR_AUTOMATIC_FLIPS.md#native-fremen-worm-ride--29-october-2026).
+
+The broader advisor selection exposed 12 fixture failures reproduced on prior
+commit `ad0abfe`. The fixtures now model the Charity phase transition, a game
+without Homeworlds, and legal Advanced Atomics timing; their 40 cases pass.
