+27 October 2026. **Prototyped / Partial.** The adopted Advanced source,
+supplied physical29/printed27 F, gives CHOAM half the total eligible support
+spice with one final rounding down. Two other combatants supporting with3 and5
+therefore yield4, and3 plus3 yield3. Earlier per-combatant flooring underpaid
+those battles. See the [source authority](RULE_DECISIONS.md#authorized-source-amendment--1-october-2026).
+
+This correction changes aggregation only. Each non-CHOAM side still contributes
+`plan.support - plan.allyPayment`. That includes its own debit and the Arrakeen
+Bank contribution. Publisher E2 physical/printed10's Arrakeen Q&A explicitly
+includes the Bank's two support spice; replacing eligibility with wallet debits
+would incorrectly remove that benefit. The
+[publisher E2 book](https://www.gf9games.com/dune/wp-content/uploads/2021/11/CHOAM-Rulebook-low-res.pdf#page=10)
+supplies that omitted detail. No combined publisher worked example for every
+subsidy/funding mixture is claimed.
+
+CHOAM's own side remains excluded. CHOAM-funded allied support goes entirely to
+the Bank under supplied G. Salusa free Sardaukar, Fremen free support, fixed
+Homeworld strength and separate Banker strength spending add no paid support.
+The current native pledge admits only a mutual CHOAM donor; future third-party
+funding or generic discounts are not certified by this correction. Existing
+Banker/Bureaucrat per-payer/per-invoice rulings remain separate.
+
+The shared `game/battle-resolution-quote.ts` calculation supplies the original
+engine settlement. Native wallet debits, escrow, casualty/card cleanup, any
+revealed-Traitor suppression, explosion income, Karama redirection and once-only
+collection keep their paths. Basic has no Advanced force-payment income.
+Already queued income retains its recorded receipt; no saved field, migration,
+recalculation of settled payments or collection confirmation is added.
+
+Focused quote and actual engine payment regressions cover odd totals. Runtime
+verification uses a clearly labelled controlled battle source with real native
+plan, Traitor, response and market actions; it is not a fresh setup/full-game
+claim. Full modes, wider compositions, comprehensive assurance and deployed
+acceptance remain open.
+
+Frozen **4 affected files, 71/71**, types/lint/build and two controlled battle
+programmes pass. 13 actual native packets and 6 GameTable SSR renders verify
+one automatic4 receipt and one pending/canceled4 receipt, unchanged3/5 debits,
+original pending response text and once-only closing behavior. The explicit
+controlled fixture assigns phase, purses, armies and leader strength; it is not
+a genuine starting-game journey. No control callbacks are operated. Quote and
+engine regressions cover3+5/3+3; the existing subsidy, aid, own support, free
+support, Traitor, explosion and cancellation cases remain in the related union.
