Prototype Planetologist movement and Special-card battles

Connect capped extra range, two-origin gathering, Fremen cancellation and
saved replacement choices. Add human controls and actual first-choice AI
paths for all four profiles. Admit the exact nine base green Specials in
the actual skilled leader's weapon slot for +2 on survival, with mandatory
physical discard and no native utility effect. Reject stale dead-disc plans.

+# Planetologist rule contract
+
+Updated 13 September 2026. This note audits the movement and battle effects of the
+Planetologist Leader Skill against its physical card, the common Leader Skills
+rules, the GF9 base battle rules and designer Jack Reda's walkthrough. The connected prototype is described below; other Leader Skill effects remain separate work.
+
+## Printed effect and legal card role
+
+The physical Planetologist card instructs its owner to reveal one green
+Special card, other than a Cheap Hero, as part of the Battle Plan “in place of
+a weapon.” It adds 2 to that skilled leader disc and says to discard the
+Special after the battle. The card therefore creates a distinct legal role for
+the physical Special card:
+
+- it occupies the Battle Plan's weapon slot;
+- it is revealed as a Special used in place of a weapon, rather than converted
+  into a Weapon Treachery Card;
+- it supplies no projectile, poison, lasgun or other attack and does not satisfy
+  a skill or rule that requires an actual named Weapon type;
+- its printed utility effect is not activated; and
+- the exact physical card is committed to that plan and cannot also be spent
+  for its ordinary effect, Karama, Truthtrance or another pending use.
+
+The designer gives Hajr and Thumper as examples, then specifically describes
+using Family Atomics for +2 without blowing the Shield Wall. This confirms
+that Planetologist grants an alternate battle use despite the Special card's
+ordinary phase or trigger. [Jack Reda walkthrough,
+10:36–11:05](https://www.youtube.com/watch?v=XT_azRVLq_0&t=636s)
+
+The substitution is available only when the assigned Planetologist leader is
+the leader actually used in the Battle Plan. Moving the skilled leader and
+skill card behind the shield as a bluff, then selecting another leader, turns
+off both skill bands. The other leader cannot place a green Special in the
+weapon slot through Planetologist. [GF9 *CHOAM & Richese* rulebook,
+p. 9](https://www.gf9games.com/dune/wp-content/uploads/2021/11/CHOAM-Rulebook-low-res.pdf)
+
+## Current base-deck inventory
+
+The current 33-card base deck contains these eligible printed green Special
+cards:
+
+| Printed card | Physical copies | Current identities |
+|---|---:|---|
+| Family Atomics | 1 | `effect: atomics` |
+| Weather Control | 1 | `effect: weather` |
+| Hajr | 1 | `effect: hajr` |
+| Tleilaxu Ghola | 1 | `effect: ghola` |
+| Harvester | 1 | `effect: harvester` |
+| Karama | 2 | `effect: karama` |
+| Truthtrance | 2 | `effect: truthtrance` |
+
+All nine physical copies may take the Planetologist weapon-slot role. Their
+ordinary timing does not need to be legal because that printed effect is not
+being played. A pending or already committed physical card remains unavailable
+because Planetologist does not create a second copy.
+
+Cheap Hero and Cheap Heroine are printed green Special components but are
+excluded. “Cheap Hero” is the rules' generic component class for both named
+copies; each instead occupies the leader position with strength zero. The base
+FAQ also says a Cheap Hero cannot substitute for a weapon or defense.
+[GF9 base rulebook and Q&A, pp. 10,
+23](https://www.gf9games.com/dunegame/wp-content/uploads/Dune-Rulebook.pdf)
+
+For today's `baseDeck()`, `kind === 'special'` happens to select the nine
+eligible non-Hero copies. That coincidence is not the printed rule. Eligibility
+should be bound to a canonical printed-green-Special classification or explicit
+physical identities, because the code's generic `special` kind is also used by
+later expansion modules. The designer's Thumper example proves that expansion
+cards can qualify, but it does not make every future card encoded as `special`
+green or eligible.
+
+## Survival and scoring
+
+The common Leader Skills rule says a skill applies in the current battle unless
+its assigned leader is killed in that battle. Planetologist adds 2 to the leader
+disc, so the receipt is conditional on that exact leader surviving weapon,
+traitor and explosion resolution. If the leader dies, neither its printed
+strength nor the Planetologist +2 contributes to the battle total.
+[GF9 *CHOAM & Richese* rulebook, p.
+9](https://www.gf9games.com/dune/wp-content/uploads/2021/11/CHOAM-Rulebook-low-res.pdf)
+
+A captured skilled leader follows the expansion's general Harkonnen Q&A: the
+captor has only the lower battle band and only while actually using that
+captured leader. A surviving captured Planetologist may therefore use the same
+green-Special substitution and +2; the original faction has no normal movement
+band while the leader and skill are captured.
+
+## Mandatory discard
+
+The Special card's own final instruction is unconditional once it is revealed
+through this substitution: discard it after the battle. This is more specific
+than the base rule allowing an ordinary winner to keep cards played in its
+plan. The physical outcome is:
+
+| Battle outcome | Planetologist Special disposition |
+|---|---|
+| Ordinary win | Discard; the winner has no retention choice for this card. |
+| Ordinary loss | Discard under both the base loser rule and the skill card. |
+| Opponent reveals the Planetologist leader as a traitor | Discard with the traitored player's played cards; the leader dies and supplies no +2. |
+| Both leaders are traitors | Discard with the played cards; the Planetologist leader dies and supplies no +2. |
+| Lasgun–shield explosion | Discard after the battle; a killed Planetologist supplies no +2. |
+| Planetologist owner reveals the opposing leader as a traitor | Discard under Planetologist's later, card-specific instruction even though the base traitor winner ordinarily loses nothing. |
+
+The last row is a rules-specificity inference. No located publisher Q&A asks
+about Planetologist versus a successful traitor call. The physical Leader Skill
+plainly says to discard after the battle and prints no winner or traitor
+exception, so retaining it would require adding an exception absent from the
+later card. The [GF9 November 2020
+FAQ](https://www.gf9games.com/dune/wp-content/uploads/2020/11/Dune-FAQ-Nov-2020.pdf)
+confirms the general winner-retention rule, while the Planetologist card supplies
+the narrower override.
+
+“Unused bluff” needs a physical distinction. A green Special actually revealed
+in the weapon slot through Planetologist has been used in that alternate role
+and is discarded even when +2 cannot affect the result or the winner is decided
+by a traitor. A Special merely carried behind the shield but omitted from the
+Battle Plan remains in hand; no rule reveals or discards it. A plan using a
+different leader cannot legally commit the Special in Planetologist's role.
+

+  battle disposition and traitor rules.

+page](https://futurepastimes.com/dune-choam-richese) links the GF9 rulebook.
+The full local source hashes and retrieval URLs are recorded in
+`leader-skills-source-provenance.txt`.
+
+## Implementation boundary
+
+A focused implementation can expose the nine base physical copies as weapon
+slot choices only for the selected, concealed Planetologist leader. It should
+record the selected physical identity and alternate role in the sealed plan,
+apply +2 only after confirming that leader survives, suppress the card's native
+effect, and force exactly one discard after every revealed outcome. Rejected or
+canceled plan changes must release the reservation without discarding the card.
+
+Expansion eligibility should be added from each component's printed category,
+not inferred from the shared TypeScript `special` bucket. The traitor-winner
+discard row should remain documented as the explicit later-card reading because
+the sources contain no direct Q&A for that collision.
+
+## Normal movement and supported prototype
+
+The first band gives a choice for one movement: add one to normal range with a
+maximum of three, or gather physical forces from exactly two different territories
+to one shared destination using each group's ordinary range. These alternatives
+do not stack. Moving multiple selected sectors of the same territory remains one
+origin. Both groups retain normal storm, path, occupancy and force-selection rules;
+the combined move spends one movement. Hajr can provide another normal movement.
+See the [physical-card contract](LEADER_SKILLS_RULES.md) and the designer's
+[example](https://www.youtube.com/watch?v=XT_azRVLq_0&t=1153s).
+
+Fremen's native range and Planetologist are independent. With the range alternative,
+a distance-two move needs only ordinary range one plus Planetologist. Distance
+three without city ornithopters uses the Fremen advantage and opens its real
+Karama response. Cancellation leaves forces and the movement opportunity in place;
+the replacement may still use Planetologist. A gather using Fremen range two also
+retains that response, with both origins saved and revalidated before continuation.
+This applies the [existing cancellation contract](FREMEN_MOVEMENT_KARAMA_RULES.md),
+not a new phase-wide restriction or an automatic shortened destination.
+
+The [November 2020 FAQ, p. 4](https://www.gf9games.com/dune/wp-content/uploads/2020/11/Dune-FAQ-Nov-2020.pdf)
+and [base rules, p. 18](https://www.gf9games.com/dunegame/wp-content/uploads/Dune-Rulebook.pdf)
+determine a common Bene Gesserit arrival stance when no other faction is present,
+or when existing BG forces determine the stance. The prototype supports mixed
+advisor/fighter origins in those cases, and uniform origins generally. Source
+advisor locks carry forward. Mixed origins entering an enemy-only territory need
+a combined advisor-flip/cancellation continuation and remain explicitly guarded;
+this is an implementation gap, not a rule that forbids every mixed move. No source
+was found granting a chosen group order that makes fighters arrive as advisors.
+
+The current runtime supports only the six base factions and the nine base green
+Special copies above. Expansion rosters, other optional modules, No-Field and
+Discovery/Richese flight combinations remain gated. Before enabling Ix, calculate
+range for each selected origin's own cyborgs and extend its cancellation trigger
+for Planetologist's added range. Aggregate elite counts must not lend one group's
+cyborg speed to a separate suboid-only origin. The expansion green-Special inventory
+must also be audited before admitting those physical cards.
+
+The movement control builds ordinary authoritative actions with an explicit range
+or gather choice. Bots use the same range helper and submit physical source/elite
+counts. Saved Fremen continuations bind the selected skill leader, choice and exact
+two-origin list; stale custody or receipts reject before spending a response card.
+The weapon selector exposes eligible Specials only for the selected skilled leader
+and explains +2 and mandatory discard. Bot candidates use that same eligibility and
+pair validation. This is a connected prototype with partial combination coverage,
+not complete Leader Skills compliance or a publication gate.
+
+## Verification evidence, 13 September 2026
+
+The final focused union passes 84 cases, including the 24-case Planetologist
+union and existing skills, Fremen cancellation and battle quote regressions.
+Independent movement and battle review closed after the stale already-dead disc
+reproducer was fixed. First-choice tests prove all four bot profiles actually use
+both alternatives in suitable fixtures. Two source-bound full-game samples finish
+with zero rejected actions and six saved restorations each; Basic executes both
+movement choices, Advanced executes boosted range. These do not establish full
+combination acceptance or calibrated difficulty ordering.
+
+The browser journey verifies genuine setup, range availability, physical gather,
+private refresh and the weapon selector's Special role. A separately staged battle
+in that new QA room verifies traitor-loss cleanup, one Special discard, skill death
+return and the unchanged Shield Wall. [The checkpoint record](IMPLEMENTATION_STATUS.md)
+separates those fixtures from the complete-game samples. Required broad check
+results, source fingerprints and saved-game comparisons are retained privately
+outside the checkout and reported in the verified commit.
