On a wire the native PCCC path is proven only for N-file reads/writes and one F8 read (ab_server). An absent transport key now resolves to Libplctag for every family; explicit Native still wins and still warns once per instance on PLC-5/LogixPccc. AdminUI dropdown, CLI help, evidence claims (PcccFileType, AbLegacy.md wire-evidence table, release note) corrected: S:0 (default probe) and B/T/C/R/S/L/ST/A/O/I are unverified natively.
