Connect Basic Ixians to the full Leader Skills prototype

Admit genuine Basic Ixian setup with the full fourteen-skill deck, real
starting-card choice, optional Tleilaxu/base opponents and first-Storm HMS.
Keep public starts, Advanced and other module combinations gated.

Share per-origin cyborg movement range across engine, controls and legal bots.
Preserve independent Planetologist range after native Karama cancellation.
Connect Sandmaster force routes through room-local HMS pointer adjacency.
Retain canceled movement's no-op contract while validating actual execution.

Resolve Suk rescue before substitution with explicit ambiguous cyborg rescue
origins and exact remaining Tank losses. Finish Rihani before native
substitution, bind saved physical losses and declared exchange, and resume
mandatory/optional winner disposal on allow, decline or cancellation.
Admit exact green Ix Thumper, Harvester and Amal as Planetologist substitutes.

Validation: types, lint, 5,082 offline tests and production build passed.
Five genuine 2-6 player games completed with zero rejected actions and 54
JSON restores. Authenticated in-memory concurrent starting-card recovery,
private setup, physical card/force custody and independent review passed.
Browser FLGHBSA4 completed real setup, first Storm/HMS placement and a
conserved staged Suk battle. Mobile rescue, refresh and one-for-one
substitution passed. Screenshot capture timed out; full visual acceptance
remains open. All 1,582 prior rooms, 3,350 human seats and auxiliary records
were preserved; one new QA room/seat remains. No restart, reset or automation.

AI work remains limited to legal participation until every non-AI feature
is complete, then targets roughly 75% higher-tier wins for each adjacent pair.

+# Basic Ixians with Leader Skills
+
+Connected development prototype, 21 September 2026. Genuine Basic Ixian setup
+now supports the full fourteen-card Leader Skills deck, optionally alongside
+Tleilaxu and base factions. Public starts and completion/publication gates remain
+closed. Existing missing skill bands are not certified by this admission.
+
+## Setup and configuration
+
+Use Basic rules, exactly Ixians & Tleilaxu, two through six players including
+Ixians, and no other optional modules. The real private Ixian starting-card
+choice precedes simultaneous private skill offers, then public assignments,
+Traitors and native Face Dancers. The first Storm retains actual HMS placement
+and all seven cyborgs/thirteen suboids. No dealt card determines admission.
+
+Create and ready a fresh local lobby, then follow the backed-up version-checked
+[prototype entry](IX_PROTOTYPE.md) using profile `leader-skills`.
+The shared initializer retains the [Tleilaxu integration](TLEILAXU_LEADER_SKILLS.md).
+
+## Connected interactions
+
+- Planetologist calculates each gathered origin's range using only cyborgs
+  selected from that origin. Selected sectors within the same territory share
+  their moving group. Its range bonus independently survives native movement
+  cancellation; a three-territory cyborg move still opens the proper Karama
+  window. Independent city ornithopters do not create that native window.
+- Sandmaster routes can enter or leave the HMS interior through its current
+  pointer. Adjacency belongs to the room, respects the storm and never turns the
+  interior into a shortcut or relocates the HMS. Interior battles and spice
+  effects remain distinct from the external pointing sector.
+- Suk Graduate finishes rescue before native substitution. Kept cyborgs and
+  cyborgs returned to reserves are excluded from the actual Tank-loss map. Where
+  more than one reserve-rescue origin is possible, the player explicitly selects
+  it; only cyborgs truly lost in each sector can be substituted there. Normal
+  rescued-force origins need no extra choice because no subsequent effect here
+  depends on them. This exposes existing physical choices, not a new rescue power.
+- Rihani finishes its private exchange before substitution. A saved receipt
+  binds original losses, physical counters, cards and the declared exchange.
+  Substitution allow, decline and cancellation all resume mandatory then optional
+  winner cleanup; Planetologist substitutes cannot escape disposal.
+- Thumper, the additional Harvester and Amal are the expansion's green Special
+  cards eligible for Planetologist substitution. Exact physical identities,
+  names and effects are checked. Their native effects do not execute during
+  substitution; other cards in the engine's broad Special bucket are excluded.
+
+## Sources and interpretation
+
+Existing [Leader Skills rules](LEADER_SKILLS_RULES.md),
+[Planetologist contract](PLANETOLOGIST_RULES.md),
+[Suk Graduate contract](SUK_GRADUATE_RULES.md),
+[Sandmaster routes](SANDMASTER_MOVEMENT.md) and
+[Ix rules](IX_PROTOTYPE.md) supply the established powers, physical custody and
+skill-before-faction precedence. Rescue-sector selection records the physical
+choice needed to compose those powers without reviving an already rescued counter.
+
+The canonical green Ix card inventory was checked directly against the printed
+components visible in this [component photograph](https://static.lelekan.ua/image/cache/catalog/igri/dune-ixians-tleilaxu-expansion-eng/dune-ixians-tleilaxu-expansion-gale-force-nine-eng-lelekan-components-2-800x800.jpg).
+This is physical component evidence, not a retailer's rules interpretation.
+Thumper also appears in the existing designer Planetologist example. The private
+source archive records SHA-256
+`6d2eb22889059edc8b35b9cd1178b6907312132b1b41768051d15abcc9c89125`.
+Sandtrout is a brown Spice card; red/blue battle cards do not qualify.
+
+## Verification and remaining scope
+
+```sh
+npm test -- ix-skills
+node --import tsx tools/faction-games.ts --profile ix-skills --out /private/new-ix-skills-samples
+```
+
+The sample profile adds Tleilaxu, Emperor, Guild, Harkonnen and Fremen in order
+and preserves stable scenario ordinals 26–30. Focused tests use all fourteen
+genuine assignments and conserved battle/movement positions, with legal actions
+from existing AI profiles, controls, private views, strict rejection and JSON
+continuation. In-memory authenticated recovery verifies exactly one concurrent
+starting-card choice, subsequent private setup and unchanged seats. Final
+source-bound check/build, samples, browser and preservation reports remain private.
+These are playability checks, not AI strength studies.
+
+Advanced Ixians, additional faction/module combinations, Sandmaster's extra
+native HMS relocation band and the other missing Leader Skill effects remain
+separate work. Existing Banker, Mentat, Diplomat and modified-Smuggler questions
+remain in the [decision register](RULE_DECISIONS.md). Full AI implementation and
+difficulty tuning wait until all non-AI game features are complete.
