.SYNOPSIS
    Captures the native AVEVA client's GetTagExtendedPropertiesFromName (GetTepByNm) wire traffic
    (HCAL roadmap R1.5) so the WCF op name, the string-handle format, the tagNames request buffer,
    and the extended-property response buffer can be decoded instead of guessed.

.DESCRIPTION
    Drives the .NET-Framework NativeTraceHarness's tag scenario with --retrieve-extended-properties,
    which flips TagQueryArgs.RetrieveTagExtendedPropertyInfo and then calls
    TagQuery.GetTagExtendedPropertyInfo(start, count, out TagExtendedPropertyGroupList, out err) —
    the managed method that issues the GetTepByNm op. An IL-rewritten copy of aahClientManaged.dll
    logs every MDAS body (ClientMessageEncoder.WriteMessage + ReadMessage), the same pipeline that
    produced every other proven request/response shape.

    Decode with scripts/decode-tag-properties-capture.py: locate the WCF.WriteMessage.Body whose op
    is aa/Retr/GetTepByNm -> that is the request (string handle + tagNames buffer + sequence). The
    paired WCF.ReadMessage.Body is the extended-property response buffer.

.NOTES
    Read-only metadata call; no data is written. Artifacts are diagnostic and gitignored.
    Sanitize before copying anything into docs/ -- never commit raw capture NDJSON, credentials,
    hostnames, or customer tag names. SysTimeSec is a built-in system tag (safe to name).
