+## Advanced advisor card movement — 18 October 2026
+
+**Prototyped / Partial.** The authorized supplied Advanced source,
+physical28/logical26, says advisors do not count as occupying a stronghold for
+ornithopter access. Physical10/logical8 likewise excludes advisors from granting
+city access, while permitting a player with eligible city forces to move forces
+elsewhere. Neither passage gives the prior blanket ban on an advisor using the
+separately named physical card. The photographed card supplies its own
+three-territory move or two different normal moves without a faction/stance
+exclusion. This cutover supersedes the older advisor guard and source assessment
+below; it is not a newly located publisher-specific card FAQ.
+
+Both modes now permit advisor groups. The range3 mode supplies its printed
+independent maximum. Two-group mode uses current normal range at each actual
+move: advisors alone in a city grant no access; fighters do. An advisor arriving
+alone automatically becomes a fighter and can therefore enable the second group.
+Leaving the last city fighter removes that access even if advisors remain in
+another city. Existing advisor/fighter arrival, new-advisor locks, same-territory
+stance, native response windows, storm/entry and distinct original force quotas
+continue to govern. This is no new shipment, stance privilege or free replay.
+
+The isolated control gives persistent Advanced BG guidance. Minimal bot card
+candidates use the shared advisor-aware route and native entry checks, alongside
+current fighter-city access and original group quotas. No strategy tuning.
+Two disjoint implementation lanes plus owner integration pass frozen **10
+files87/87**, types/lint/build and three original-action/rendered-table
+programmes. Each starts with58 actual source actions: original Advanced host,
+BG advisorSetup in native Atreides Arrakeen, cache1 purchase, Richese1 shipment,
+actual free accompaniment and BG2 Polar Sink or1 Carthag reinforcement. Only
+original scalar lotteries and unopened first-turn Spice positions are selected;
+no postdeal hand, wallet, force, stance or clock is installed.
+
+Range3 has2 continuation actions; advisor/fighter twoGroups and last-city-fighter
+variants each have3. The real advisor source cannot use an ordinary three-range
+move without city fighters. Card range3 succeeds and empty arrival flips.
+TwoGroups retains original advisor/fighter quotas after automatic face changes;
+leaving the last Carthag fighter recomputes the second advisor group to1 even
+while advisors remain in Arrakeen. Four minimal policies supply eight legal
+initial/second-group proposals. Four controlled rule cases separately exercise
+empty-city access, occupied-city nonaccess, existing fighter-city ordinary use
+and locked advisor entry among two other factions. Six isolated control cases
+cover modes, guidance, original cohorts and disabled states.
+
+Source-bound proof is outside Git at
+`~/.local/share/dune/checkpoints/20261018-ornithopter-advisors/frozen-integrated-2/report.json`:
+base `884a09fa92c8604c943979ef2a4c29990399c0fc`, source tree
+`62adeab78469339886640fa0e852a8532f7e03d80da052a687576fc4e7110c83`.
+The narrow native case corrected only its expected-error matcher; type feedback
+added a nonnull annotation for the controlled fixture’s known movement list.
+The frozen related union and required checks then passed on identical source.
+Only checkpoint prose/reference evidence changed afterward.
+
+GameTable snapshots use genuine views; isolated controls render the actual
+accepted first/second movement drafts. SSR does not click select/submit, and
+framework aliases/CSS stubs do not establish visual/browser/deployed acceptance.
+Other card/module combinations, full modes and comprehensive assurance remain
+due. No saved-room/database/reset/restart or deployment operation occurred.
