The rewards engine turns verified activity anywhere in the estate into Flashy Gold — rule-bound, so no Gold is minted without a reason on the record, and idempotent, so a retried award settles once, not twice. It is the reason a portfolio of products behaves like one economy.
Why one currency changes the math
A reward trapped in the product that issued it is a coupon. When effort in one property mints value spendable in another, every property that adopts the currency makes every other property’s rewards more valuable. That network effect is the whole argument for a shared currency over per-product points.
