authorization

type PreAuthorizer interface {
	// PreAuthorize validates whether the user satisfies the necessary permissions
	// as defined by the RBAC policy. It examines the user’s roles, resource identifiers, and
	// the intended action to determine if the operation is allowed. Optional additional required permissions are also evaluated
	// against user.
	//
	// Return Value:
	//   - nil: indicates that the authorization check passed and the operation is permitted.
	//   - non-nil error: indicates that an error occurred during the permission evaluation process
	//     (for example, a failure decoding the manifest or other internal issues). If the evaluation
	//     completes successfully but identifies missing rules, then a nil error is returned along with
	//     the list (or slice) of missing rules. Note that in some cases the error may encapsulate multiple
	//     evaluation failures
