 # Emperor alliance gift timing
 
+## Advanced allied auction payment — 29 October 2026
+
+For a clean classic Advanced auction won by the Emperor's current mutual ally,
+the Emperor receives a uniform opportunity to give spice before the original
+payment. The same public waiting window appears whether the buyer holds Karama
+or the Emperor has available spice; only the Emperor sees the gift amount
+available. Continue leaves payment to the buyer or the existing automatic
+settlement. A gift's Karama response retains the original lot, bid and
+committed payer split; allowing it credits the buyer once, while cancellation
+transfers nothing. Gifted buyer spice follows the buyer's normal payment route;
+the previously pledged Emperor contribution remains separately accounted for.
+
+The uniform priority and explicit Continue are provisional online timing for
+the authorized Advanced rules' any-time power, not publisher instructions.
+The same Continue is currently required even when the Emperor has no spice;
+this protects the private balance but still needs refinement to meet the
+project's no-confirmation requirement for forced automatic actions.
+Older already-open payments do not acquire a new window. Other auction modes,
+optional modules and live commitments needing a combined planner remain
+unfinished. [Runtime cases](../tests/emperor-auction-gift.test.ts) use real
+setup, alliance and bids with explicitly staged balances and cards;
+[rendered controls](../tests/emperor-auction-gift-controls.test.tsx) cover the
+table and owner-only opportunity.
