.SYNOPSIS
    Captures the native AVEVA client's AddTagExtendedProperties / DeleteTagExtendedProperties wire
    traffic (HCAL roadmap R1.11) so the AddTEx / DelTep inBuff layout can be decoded, not guessed.

.DESCRIPTION
    Drives the .NET-Framework NativeTraceHarness's `add-tep` scenario against the live Historian with
    an IL-rewritten copy of aahClientManaged.dll whose ClientMessageEncoder.WriteMessage AND
    ReadMessage are instrumented. The harness opens a WRITE-enabled connection, creates a sandbox tag
    (RetestSdkWrite...), and calls AddTagExtendedProperties(TagExtendedPropertyGroupList, out err) with
    one string property (and DeleteTagExtendedPropertiesByName when -Delete).

    Decode with scripts/decode-add-tep-capture.py: the WCF.WriteMessage.Body whose op is AddTEx carries
    the inBuff (tag name + property name/value); DelTep carries the delete inBuff (tag + property names).

    SAFETY: sandbox-guarded — the tag MUST start with 'RetestSdkWrite'. Default run leaves the tag +
    property in place (unless -Delete); pass -Delete to also capture DelTep and remove the property.
