zuraffa_purchase 0.1.1

Purchase support for the Zuraffa ecosystem: a typed in-app purchase port behind a service, with the StoreKit / Play Billing adapters shipped as federated siblings.

Changelog

0.1.1

• PurchaseSubscriptionStore now speaks the port's own error vocabulary: a PurchaseException raised by the purchase port leaves the adapter as a SubscriptionException carrying the same machine code and message. A consumer that catches on SubscriptionException — as zuraffa_subscriptions documents the port — now catches the failure too. Any other error propagates unchanged, and an unrecognised purchase-domain code surfaces as store_unavailable.
• ScriptedPurchasePort — the scriptable double for the purchase port seam, the twin of RecordingStoreApi on the store seam. A consumer can now drive the purchase domain, including its failure paths, without a device and without a platform adapter.

0.1.0

• Initial release of the app-facing purchase domain: PurchasePort, PurchaseService, CatalogProduct, PurchaseOutcome, PurchaseStatus, PurchaseIntent and the typed PurchaseException taxonomy.
• StoreApiPurchasePort adapts the store seam (StoreApi) to the port, and RecordingStoreApi is the scriptable test double the package ships for apps that want to drive the store in tests.
• PurchaseSubscriptionStore implements the SubscriptionStorePort of zuraffa_subscriptions, so a consuming app hands a real store straight to SubscriptionService instead of writing its own adapter.
• registerPurchaseDependencies wires the port, the service and the subscription store as lazy singletons; the registration order does not matter, and an unwired store surfaces the typed PurchaseNotWired failure.
