Flashtalking state trackers carry a five-part tuple.

The official Tag Assistant recognizer identifies placement, creative, version, event and impression fields on legacy state paths. Numeric fields and a nonempty impression ID receive template checks.

The recognizer establishes the observed transport shape. It does not establish a closed event vocabulary or verify the surrounding ad session.

Apply the contracts within their published source scope.
