 Primary-source and integration audit, 10 September 2026, with dated Secret Ally revival, protection and native Cunning prototypes. These bounded paths do not certify complete Fremen/Nexus effects or open a release gate. The [common Nexus rules](NEXUS_CARD_RULES.md) apply.
 
+## Native modules, remote riding and Great Maker — 18 October 2026
+
+**Prototyped / Partial.** Native Fremen Nexus
+effects now use the original initialized card module and registered selected
+roster rather than a classic-only configuration gate. Original host setup and
+module prerequisites still apply; no played game is converted or given a card.
+Worlds, training, phase modules and selected independent decks retain the same
+actual appearance, physical card cost, Betrayal declaration and typed ride.
+
+An ordinary initially empty worm offers the same public native Cunning choice
+whether Fremen holds the card or not. Actual entitlement controls spending;
+the original worm, applicable Nexus and ordinary rides finish before the
+authenticated remote ride. All selected normal/Fedaykin counters come from one
+printed desert; reserves, Homeworlds and Discovery strongholds are not desert
+sources. Room-local revealed Discovery destinations use their actual locations.
+HMS entry requires its actual pointer's parent to match the chosen source
+territory; its structure is not moved by the ride. Hidden/unplaced destinations,
+storm and occupancy retain their own entry restrictions.
+
+A living available native Sandmaster can collect one spice at the remote ride's
+destination. Collection is optional and uses the original shared destination-
+pile quote; multiple source sectors do not multiply it. No source or imagined
+intermediate territory supplies spice. The same multi-pile choice convention
+as ordinary worm riding remains provisional. This still uses neither ordinary
+movement nor a reserve shipment.
+
+The [publisher E3 rules, printed12](https://www.gf9games.com/dune/wp-content/uploads/EcazMoritani-Rulebook-LOWRES.pdf#page=12)
+and supplied revision physical23/logical21 replace ordinary board-origin
+riding with Great Maker reserve riding; native Karama killing the board group
+does not cancel that reserve ride.
+Under the recommended source composition, predeclared turn-long Fremen Nexus
+worm-riding prevention therefore also suppresses the reserve ride; votes,
+destruction, spice and the actual Nexus continue. This is not a newly located
+Nexus/Great Maker FAQ or a Karama cancellation. The replacement encounter itself
+does not invent another Cunning board ride. Its completed historical frame does
+not suppress a later ordinary empty-worm appearance.
+
+Source and pure helpers: `game/fremen-nexus-profile.ts`,
+`game/nexus-fremen-cunning.ts`, `game/nexus-fremen-betrayal.ts`,
+`game/sandmaster-worm.ts`. Original-action fixtures and focused module cases
+accompany these helpers; complete combinations, comprehensive assurance,
+full AI and deployed acceptance remain open.
+
+The owner-frozen **14 files86/86**, types/lint/build and nine finite original-
+action/table-SSR programmes pass. Original paid Karama supplies a real response;
+typed World/all14 riding, Sandmaster, HMS and both Betrayal modes use actual
+setup/actions. A genuine Maker/second-pile sequence proves the completed-frame
+fix. Four legal policies retain Cunning and both declarations. Discovery

 ## Evidence
 
 The Fremen panel was freshly read from the [photograph of the printed GF9 cards](https://boardgamegeek.com/image/7767032/dune-ecaz-and-moritani), cached as `/tmp/dune-nexus-cards.jpg`. Cunning permits a remote ride when a sandworm appears in a territory containing no forces: the player may take forces from one desert territory to a destination respecting storm and occupancy rules. Secret Ally offers either protection against a sandworm or a total of three free force revivals during Revival. The latter does **not** use Emperor's additional/beyond-limits wording. Neither option grants the absent faction's other advantages.

 `game/nexus-fremen-cunning.ts` captures `{event, turn, territory, origin, pile?, parent?, initiallyEmpty}` at the accepted appearance before destruction, using public `presenceAt` across players. Advisers and public No-Field markers count without revealing marker denomination. `beginWorm` offers the same Fremen decision for an initially empty appearance whether or not that seat holds its own card; the owner-only card view controls the spend button. The server, not the client, issues the event and later `{event, turn, owner}` ride authorization. The actual Fremen card moves to the Nexus discard on acceptance.
 
 The current runtime path covers natural and accepted additional worms in Basic/Advanced, plus Fremen special-Karama summoned worms in Advanced, with seated classic factions and Nexus, optionally retaining original Tech Tokens3+ and/or Advanced Stronghold Cards2+. Skills, Homeworlds, Discovery and expansion factions/decks stay outside this Cunning boundary. The summon mints a separate server-side parent event when its physical Karama is spent; a new empty appearance binds the Cunning occurrence to that parent before devouring. A saved offer or pending ride must still belong to the active summon. A summon occurring inside another unresolved Cunning offer or ride retains its ordinary worm path without a second Cunning offer. Great Maker is not enabled for this Cunning path; Sandtrout-suppressed and first-turn ignored *drawn* worms never call the appearance hook, while a real special summon still does. `quoteFremenCunning` checks native unallied entitlement and lists typed forces in each occupied sand territory. After spending, `quoteFremenCunningRide` requires the saved event authorization and spent physical card; `validateFremenCunningSelection` requotes one source and a subset of normal/Fedaykin counters immediately before moving. The destination uses Arrakis entry, storm and occupation rules, not the desert-only source restriction. Ordinary worm destruction and the applicable Nexus happen first; `nextWormRide` schedules native rides before the remote ride afterward, without consuming normal movement. BG intrusion and territory-entry continuations use the native worm-ride path. JSON normalization and rejected-action checks cover a live offer, a spent response and the post-Nexus selection.

 # Sandmaster worm-ride collection
 
+## Native Cunning remote ride — 18 October 2026
+
+**Prototyped / Partial.** The original authenticated
+Fremen Nexus Cunning ride can optionally collect one destination spice using
+`sandmasterCunningCollection(game, player, source, destination, sector, selectedPile?)`.
+It requires the living available native trainer and the actual pending remote
+ride. The selected source must be an occupied printed desert; the already
+resolved empty worm's territory is not substituted for that source.
+
+The accepted ordinary Cunning action adds the same optional `sandmasterCollect`
+and `sandmasterPile` fields as native worm riding. The engine requotes the
+typed source, destination and original positive pile before moving any force or
+spice. Collection debits one destination pile once, regardless of force count
+or source sectors. Omitted/false collection preserves the underlying ride;
+invalid collection rejects the request. This does not spend normal movement,
+touch World reserves, or collect from a source or invented intermediate route.
+
+The original shared checkbox/pile controls and minimal bot choices use the same
+quote. Original multi-pile selection remains a provisional allocation policy;
+[Fremen Nexus timing and boundaries](NEXUS_FREMEN_RULES.md#native-modules-remote-riding-and-great-maker--18-october-2026)
+remain separate from complete module and deployed acceptance.
+
+Owner-frozen related14-file86/86, types/lint/build, genuine six-seat trained
+World Cunning and actual HMS programmes pass. Destination6→5 pays the native
+trainer one spice; false/omitted collection still rides, and a stale pile or
+nonboolean flag rejects. All four policies retain legal original choices.
+The actual shared checkbox is rendered from its pending source-bound quote;
+table SSR is not visual/browser acceptance. [Shared proof and limits](NEXUS_CARD_RULES.md#native-fremen-nexus-modules--18-october-2026).
