Podscribe impressions check the PRX tracking template.

Warning-only completeness checks for the official PRX /pxl example, selected only by exact plt=prx. Macro slots may be empty; IP and user agent may use headers. Creative names and event values stay open. This profile does not apply the unrelated /tag S2S table or prove receiver requiredness, identifier issuance or attribution.
