Quintine 7e3bec2721 Implement the five 7 October pending rule rulings
The user answered five recorded questions; each ruling is indexed in
RULE_DECISIONS.md and implemented with a focused regression.

- CHOAM opening income counts as a qualifying collection, so low-population
  Tupile adds its bank increment under the Inflation multiplier. The engine
  guard is removed and the projection/notice expose the added bonus.
- An exhausted Richese cache is legal and restores one ordinary lot; the
  canceled/prevented compulsory cache auction branch restores the reduction
  before the ordinary pool runs and the cache offer is skipped when no cache
  lot can run. The pure continuation quote mirrors the count.
- Suk-rescued casualties count toward Advanced Atreides' seven Kwisatz
  Haderach losses: the battle-loss counter gains the full dialed allocation in
  both rescue paths, and the earlier Suk availability restriction is removed.
- The Guild Nexus Secret Ally reserve return overrides the Arrakis-to-native-
  Homeworld restriction for the holder's own reserves and deposits through the
  shared native-reserve pipeline (generalized from the revival deposit).
- Interior passengers count as entering the territories a relocated Ixian HMS
  points into, so Sandmaster collects there before the native collection.

Full offline suite 7804/7804, types and lint pass. Historical evidence and
superseded test expectations are updated to the ruled behaviour; preserved
combined Homeworld/Nexus, occupation and Richese captures are unblocked but
not re-run here. No existing game, seat or saved state was changed.

Raw Blame History

Sandmaster movement collection

13 September 2026. Prototyped, with Partial rules coverage. Ordinary ground movement now connects the normal band through explicit routes, optional collection, player controls, all four AI profiles and saved continuation. This does not open public Leader Skills starts or publication.

Source contract

The physical card and Jack Reda's designer walkthrough, 15:48–16:08 allow immediate collection of one spice when forces move into or through a territory containing spice, once per territory. The GF9 CHOAM & Richese rules, pages 8–9 and 12 require a living native trainer for this normal band; a captive supplies only the lower battle band. Common skill resolution precedes faction abilities. The existing source archive contains the checked physical face and timestamped designer transcript.

The route's initial territory earns nothing merely for being the source. Crossing into an intermediate or final territory qualifies, independently of the number of moving forces. A later legal re-entry into the source can qualify; each distinct entered territory still grants at most one collection. Moving between sectors without leaving the source territory earns nothing. The card says territory, so the route need not touch the spice pile's particular sector. Storm and stronghold passage restrictions still apply.

Recorded scope inference: the once-per-territory limit belongs to the movement that triggers it. A distinct Hajr movement starts another collection opportunity. No publisher or designer clarification specifically discussing Hajr was located; this follows the card's movement-triggered grammar rather than introducing a once-per-phase limit that the card does not state.

Collection commits when the legal move completes, before arrival reactions. Canceled or rejected declarations move neither forces nor spice. If several positive sector piles exist in a territory, that collection remains unavailable because the source does not specify which pile to debit. Movement and collection from other eligible territories remain available.

Implementation and verification boundary

The optional movement choice declares a connected sector route from every selected source sector and the individual territories to collect from. The engine validates the exact paths against actual range, storm and occupancy. It records the native skilled leader, original movement and pile quantities. The same shared helper supplies default routes and collection choices to humans and bots. Players may edit each route and decline any or all collection; ordinary Move retains its existing behavior with no Sandmaster collection.

A Fremen route using its two-territory advantage keeps the choice in the saved movement response, even when a shorter direct route reaches the same endpoint. The response is bound to the original choice across interruptions. Changing or removing the commitment, response or original board spice fails validation. Internal proofs are excluded from player projections. Existing versioned writes settle the physical board-to-player transfer once, with automatic explanatory history. Legacy declarations without a choice continue as ordinary movements.

Focused tests cover Basic/Advanced collection, per-territory opt-out, malformed and blocked routes, custody, Fremen cancellation and recovery, saved corruption, private views and legal candidates across four AI profiles. SQLite checks include concurrent final allowance, exact payment, canceled declarations and legacy movement. Two genuine four-profile Basic/Advanced samples finished in 196/89 actions with 6/3 JSON restorations and no rejected candidates; neither encountered Sandmaster collection. Targeted tests establish that effect. A fresh browser room assigned the offered skill through genuine setup, then used a conserved staged movement. The player edited the route from Red Chasm through South Mesa to Pasty Mesa, exercised per-pile opt-out and moved three forces. Both selected piles lost one spice; own spice rose from five to seven. Refresh retained three Pasty Mesa forces, one Arrakeen force, sixteen reserves, no Tanks and the same private Crysknife and Caid. Movement completion awaited the human. This is targeted browser evidence, not a complete human game. Broad checkpoint results are recorded with the checkpoint. These checks do not certify every skill or combined module.

The worm-ride follow-up connects native Fremen destination collection, including saved arrival reactions. Remaining work includes other nonordinary relocation, special movement cards, expansion/module integration, multiple-pile adjudication and wider interaction and strategy acceptance. The lower battle band remains in the battle-effects contract.

21 September: native HMS relocation eligibility

The Basic Ixian integration connects ordinary force entry and exit through the current HMS pointer. Native relocation is a different event: it changes the stronghold's pointing sector while its forces remain in the separate interior territory. Calling a further Sandmaster collection a known missing bonus was too strong; eligibility is unresolved.

The publisher-authored Ix rules, pages 9 and 11 give native collection of two spice per force from traversed spice-containing sectors, including departure, and prohibit movement into, out of or through the storm. Sandmaster instead requires forces moving into or through a territory and grants one total spice per entered territory. The official November FAQ, page 7 allows Karama to prevent HMS relocation and collection together.

The checked card, designer walkthrough and available official rules did not clarify whether passengers staying in the interior count as entering outside territories. Resolved 7 October 2026 by user ruling: interior passengers do count as entering the outside territories the stronghold points into, so the Sandmaster skill collects one spice per entered territory with an unambiguous pile during a native relocation, before the faction's own traversed-sector collection. Skill-before-faction precedence settles the ordering. Ordinary Sandmaster entry/exit and native relocation are unchanged; full combined compliance remains unverified.
