Perpetual app with one year of updates

import { Credits } from "@byfungsi/sapa";

export const desktopBundle = Effect.gen(function* () {
  const appAccess = yield* Access.entitlements({
    entitlements: ["desktop.use"],
    duration: "perpetual",
  });
  const updateAccess = yield* Access.entitlements({
    entitlements: ["desktop.updates"],
    duration: {
      type: "fixed",
      months: 12,
      anchor: "settlement",
      calendar: "utc_clamped",
    },
  });
  const credits = yield* Credits.pack({
    unit: "desktop.processing",
    quantity: 1_000n,
  });
  const purchase = yield* Purchase.parse({
    key: "desktop.bundle.benefits",
    revision: 1,
    provides: [appAccess, updateAccess, credits],
  });
  const billing = yield* Billing.oneTime({
    price: { currency: "IDR", amount: 1_999_000n },
  });
  return yield* Offer.parse({
    key: "desktop.bundle",
    revision: 1,
    purchase,
    billing,
  });
});

Each benefit expires independently. After twelve months the customer keeps app access and unused processing credits but loses update access.

For subscription licensing, change the entitlement duration to purchased_period and billing to subscription. Online validation then follows settled subscription periods.
