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superseded test expectations are updated to the ruled behaviour; preserved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

 - **Fremen alliance:** apply the granted rate of three, then the recipient's own low bonus. The donor's low population does not turn its printed alliance grant into four. Canceling the alliance benefit removes that source, not the recipient's independent Homeworld increment. This follows the distinct grant and native modifier; it does not add an ordinary Karama cancellation of every faction's printed free rate.
 - **Charity:** establish a valid collection first. Multiply ordinary charity and the conditional low bonus by Inflation, while keeping the bonus bank-paid. At zero spice, ordinary low charity is two from its ordinary payer plus one bank; Double makes four plus two. At one spice it is one plus one, or two plus two. Cancel produces no collection and no bonus. Advanced BG's ordinary amount is two regardless of wealth; a canceled BG charity claim similarly has no qualifying collection. These are cross-source compositions, not located worked examples.
 
-**CHOAM's own income needs an explicit integration decision.** Its initial two-per-faction payment is named the Charity advantage, and E2 expressly includes it in Inflation. This supports treating it as a qualifying collection for Tupile's low bank increment, but that parenthetical does not explicitly adjudicate other modifiers. Conversely, limiting the Homeworld bonus to ordinary poverty claims would give low CHOAM no increment on its usual initial income. No retrieved primary passage resolves that distinction. Preserve the ordinary claim and faction-income sources rather than accidentally awarding twice or silently excluding CHOAM.
+**CHOAM's own income — resolved 7 October 2026 by user ruling.** Its initial two-per-faction payment is named the Charity advantage, and E2 expressly includes it in Inflation. The user ruled that it **counts as a qualifying collection** for Tupile's low bank increment, so the low-population bonus is added under the same Inflation multiplier as ordinary charity. The engine no longer blocks low-population CHOAM opening income.
