// Package api defines flex-auth's public, backend-neutral types:
// resource manifests, subject manifests, relationship facts, policy
// package metadata, check requests, and decision envelopes.
//
// These types are the stable contract consumed by protected systems
// (Markitect first) and produced by every adapter. Schema artifacts
// in schemas/ are generated from or validated against these types.
//
// Concrete type definitions land in FLEX-WP-0002 P2.1.
