Product-owned adapter for applying and reconciling durable mutations.

Implementations own transport, authentication, product DTOs, stable/provisional identity mapping, and backend-specific status queries. Self::apply_mutation must use the intent’s idempotency identity. A transport result that does not prove whether the effect committed must return MutationRemoteOutcome::RemoteOutcomeUnknown rather than an ordinary backend error.

Required Methods

fn apply_mutation<'life0, 'life1, 'async_trait>( &'life0 self, intent: &'life1 MutationIntent, ) -> Pin<Box<dyn Future<Output = BackendResult<MutationRemoteOutcome>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Applies one idempotently identified mutation to the product backend.

fn reconcile_mutation<'life0, 'life1, 'async_trait>( &'life0 self, intent: &'life1 MutationIntent, ) -> Pin<Box<dyn Future<Output = BackendResult<MutationRemoteOutcome>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Resolves an explicitly unknown remote outcome through status or change reconciliation.
