+# • The transmitter sends the raw report and fee-token parameter to
+#   `verifyAndUpdateReport(bytes unverifiedReportData, bytes parameterPayload)`.
+# • No REPORT_VERIFIER role assignment is required; the function is public.
+# • The DataStreamsFeed contract MUST hold enough LINK (fee token) so the
+#   VerifierProxy can deduct the verification fee from the contract.
+#   Native gas for storage is, as always, paid by the caller.
