XPLN video telemetry checks the current public SDK transport.

The current public SDK emits normalized identifiers and JSON text over beacon or fetch POST. A complete request can link those producer fields to the observed transport.

Historical GET payloads have optional identity advisories only. Private fields and unpublished legacy schemas retain explicit coverage limits.

Apply the contracts within their published source scope.
