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superseded test expectations are updated to the ruled behaviour; preserved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.

+## User rulings — 7 October 2026
+
+Five previously pending questions were answered directly by the user. These are
+recorded user rulings, not located publisher passages; the source documents
+below retain the passages that left each question open.
+
+| Boundary | Ruling | Superseded question record |
+| --- | --- | --- |
+| CHOAM opening income at low-population Tupile | CHOAM's opening income (`2 × players`) counts as a qualifying collection for Tupile's low-population bank increment: add `homeworldLowBonus × Inflation multiplier` exactly as ordinary poverty charity does, instead of leaving the engine guard. | [Homeworld benefits](HOMEWORLD_BENEFITS_RULES.md) |
+| Richese exhausted/canceled cache count | When no cache lot can run — the cache is exhausted, or the compulsory cache auction is canceled/prevented — one ordinary auction lot is restored, so the ordinary pool runs its full declared count rather than the cache-reduced count. | [Richese auction boundaries](RICHESE_AUCTION_RULES.md#explicit-source-boundaries) |
+| Suk Graduate / Atreides | Counters rescued by Suk Graduate count toward the seven force losses that activate Kwisatz Haderach (raw dialed casualties), so Suk is no longer withheld in Advanced Atreides. | [Suk Graduate rules](SUK_GRADUATE_RULES.md#atreides-loss-count-question) |
+| Guild Secret Ally / Homeworlds | The Nexus Secret Ally reserve-return grant overrides the Arrakis-to-native-Homeworld restriction for the holder's **own** native reserves only; arbitrary foreign-Homeworld transport stays unavailable. | [Homeworld return](NEXUS_GUILD_SECRET_ALLY_RULES.md#homeworld-prices-and-the-unresolved-return) |
+| Sandmaster / native HMS relocation | Forces remaining inside a relocated HMS interior count as entering the outside territories the stronghold points into, so Sandmaster grants its per-entered-territory collection for those territories. | [Native HMS relocation eligibility](SANDMASTER_MOVEMENT.md#21-september-native-hms-relocation-eligibility) |
+
+Each ruling changes only the specific combination named. Ordinary behaviour the
+sources already established (ordinary charity, ordinary Richese auction counts,
+non-rescue losses, ordinary Arrakis routes and ordinary Sandmaster entry/exit)
+is unchanged. Implementation, guidance and tests follow the ruling; the retained
+documents above keep their original source analysis.

 | Reinforcements cost | The user question still asks whether to keep the card disabled, always transfer three reserve forces on every outcome, or waive only a sole traitor-call winner's cost; no answer is assumed. The bounded classic and Ecaz/Moritani prototype provisionally charges on all revealed outcomes, chooses normal reserves before elite and counts the transfer as battle losses. Those are product interpretations, not a ruling. Same-plan Harass/Stone Burner remain gated; opposing Harass is supported. Eligibility never depends on concealed matching Traitors. | [Source cost review](ECAZ_TREACHERY_RULES.md#14-september-reinforcements-cost-review) · [Bounded runtime](REINFORCEMENTS_RUNTIME.md) |
 | Harass / Stone Burner | A user question has been sent: keep the combination gated or compare forces remaining after withdrawal. No answer is assumed. The Richese card-family configuration is guarded publicly; hidden Stone Burner custody never controls eligibility. Ambiguous physical allocations and other optional modules remain unfinished. | [Current boundaries](HARASS_WITHDRAW_RUNTIME.md#current-boundaries) |
 | Recruits late accounting and rates | A user question has been sent for two free plus one paid Atreides return before Recruits: keep the disputed case gated, or one/two further free returns without refund. No answer is assumed. Late-changing free rates, pending repricing and same-turn recovered-card replay also stay gated. The connected clean-case preview retains the independent seven-force cap after faction-advantage cancellation as an explicit inference, not a direct combined FAQ. | [Source audit](RECRUITS_RULES.md), [runtime scope](RECRUITS_RUNTIME.md) |
-| Sandmaster / native HMS relocation | No official source located establishes that passengers remaining inside the HMS enter outside territories for this skill. Extra collection eligibility is pending a user ruling; native sector collection and ordinary force entry/exit remain available. | [Source comparison and question](SANDMASTER_MOVEMENT.md#21-september-native-hms-relocation-eligibility) |
 | Sapho remaining timing | First versus unspent Advanced Guild priority, partly completed combined turns, cyclic auction duration and later battle timing stay guarded. The existing pre-plan opportunity supports [early aggressor](SAPHO_AGGRESSOR.md). Prior questions remain unanswered. | [Source audit](JUICE_OF_SAPHO_SOURCE_UPDATE.md), [battle review](JUICE_OF_SAPHO_BATTLE_REVIEW.md) |
 | Semuta Drug | Full-hand exchange is user-approved; neutral all-seat acknowledgements remain the explicit application policy. Other discard producers, nested continuation coverage and full-game acceptance remain unfinished. | [Source update and selected exchange](SEMUTA_SOURCE_UPDATE_20260907.md), [privacy review](SEMUTA_PRIVACY_REVIEW.md) |
 | Leader Skills edge cases | Capture/replacement eligibility, Banker escrow custody, Smuggler modifier/allocation boundaries, Mentat empty-hand fallback, modified Diplomat defenses and simultaneous optional timing remain source gaps. After an online publisher/designer/tournament check found no explicit priority ruling, the bounded standalone Diplomat retreat prototype explicitly chooses printed/copied disc strength and a surviving-loser retreat before ordinary casualties; other combinations remain guarded. This is an implementation interpretation, not an official clarification. | [Material boundaries and selected retreat interpretation](LEADER_SKILLS_RULES.md#bounded-diplomat-retreat-interpretation), [Diplomat defense boundary](DIPLOMAT_DEFENSE.md#evidence-and-remaining-scope) |
 | Smuggler collection strength | A fresh primary-source check found no modifier ruling. The user was asked whether to keep affected combinations gated, use printed/copied disc value, or include leader bonuses with Stunner zero. No answer is assumed. The reveal-bound deferred receipt is supported as an explicit timing inference; unmodified lower collection is now [prototyped](SMUGGLER_BATTLE.md); modified strength, multiple positive piles and combined modules remain gated. | [Smuggler follow-up](LEADER_SKILLS_RULES.md#20-september-smuggler-follow-up) |
-| Suk Graduate / Atreides | Whether rescued dialed casualties count toward the seven-loss Kwisatz Haderach threshold remains unresolved. The user question has been sent; Advanced Atreides rescue stays guarded. | [Source and runtime boundary](SUK_GRADUATE_RULES.md) |
 | Ordinary Guild cancellation | Unaffordable repricing, replacement/retry/decline, consumed opportunity, contributor adjustment and ordering with special shipment-stop. The affordability question was already sent. | [Material timing](GUILD_RATE_KARAMA_RULES.md#material-unresolved-timing) |
 | Base special Karama | Unfunded auction recovery, stopped-shipment settlement and Atreides full-plan commitment order remain provisional. Native full-plan/Voice/Prescience/Truthtrance/Ghola interactions now have genuine-setup focused evidence, but the source audit does not settle the special offer/deadline or target-first interpretation. | [Explicit base interpretations](BASE_ADVANCED_READINESS_20260907.md#explicit-unresolved-base-interpretations), [full-plan interaction audit](ATREIDES_FULL_PLAN_TIMING.md) |
-| Guild Secret Ally/Homeworlds | Whether the reserve-return grant overrides the Homeworld return restriction. The question was already sent; that route stays guarded. | [Homeworld return](NEXUS_GUILD_SECRET_ALLY_RULES.md#homeworld-prices-and-the-unresolved-return), [checkpoint](NEXUS_GUILD_SECRET_ALLY_RUNTIME.md) |
 | Occupied Homeworlds | Entitlement/expiry after departure, replacement or contest; unique powers and shared income. The first-occupier/current-occupier question was already sent. | [Occupation questions](HOMEWORLD_OCCUPATION_RULES.md#questions-the-retrieved-sources-do-not-settle), [lifecycle audit](HOMEWORLD_OCCUPATION_LIFECYCLE_AUDIT.md) |
 | Nexus responses and composition | Betrayal private-response timing, partial revival/payment choices, Emperor fewer-than-five, fresh advisor/storm cases, Duke restoration and remaining faction-specific combinations. Tleilaxu Secret Ally force accounting, leader slot/eligibility and force-only use remain unresolved after requested publisher/designer source searches; do not infer answers from native Tleilaxu revival or Ghola. | [Common boundaries](NEXUS_CARD_RULES.md#remaining-source-questions-and-release-boundaries), [Tleilaxu source search](NEXUS_TLEILAXU_RULES.md#source-search-follow-up) and individual faction source/runtime documents |
 | Moritani Atomics after alliance change | The publisher's persistent −1 hand-limit text names Moritani and “your ally,” but not whether the penalty follows a later ally, remains on the original ally or affects both. Requested online source searches found no clarification; the alliance-change case remains gated. | [Terror source boundary](MORITANI_TERROR_RULES.md#material-gaps-and-ordinary-compositions) |
