+        responses.
+
+        Servers *MUST* ensure Fetch'd content matches all the specified
+        qualifiers except in the case of previously Push'd resources, for which
+        the server *MAY* trust the pushing client to have set the qualifiers
+        correctly, without validation.

+        Servers not implementing the complementary [Push][build.bazel.remote.asset.v1.Push]
+        API *MUST* reject requests containing qualifiers it does not support.

+        here; errors outside the server's control will be returned inline in the
+        `status` field of the response (see comment there for details).
+        The possible RPC errors include:
+        * `INVALID_ARGUMENT`: One or more arguments were invalid, such as a
+        qualifier that is not supported by the server.
+        * `RESOURCE_EXHAUSTED`: There is insufficient quota of some resource to
+        perform the requested operation. The client may retry after a delay.
+        * `UNAVAILABLE`: Due to a transient condition the operation could not be

+
+        In the case of unsupported qualifiers, the server *SHOULD* additionally
+        send a [BadRequest][google.rpc.BadRequest] error detail where, for each
+        unsupported qualifier, there is a `FieldViolation` with a `field` of
