// Package servingbindingv1 defines the neutral, immutable value carried by a
// Catalog serving-compatibility receipt for one Runtime workload.
//
// Catalog remains the sole selector: it publishes the content-addressed
// receipt digest on its active binding, and Runtime reads that same receipt.
// This package neither selects a binding nor owns a repository, cache,
// registry, resource normalizer, scope mapping, route predicate, or product
// tool definition. CanonicalResource, ToolContractDigest, and
// ScopeRouteReceiptDigest are exact, opaque facts supplied by their
// authoritative producer; Runtime compares them byte-for-byte.
