Trade press same-day coverage of AP2 is corroboration, not a primary source

zFinia prefers the Google Cloud post. This record shows how secondary reports are filed.

TechCrunch reported Google’s AP2 launch on 16 September 2025, describing backing from merchants and financial institutions. zFinia treats this as TIER_C corroboration of an already TIER_A official announcement.

Why it matters

Methodology: official vendor posts outrank aggregators. Aggregators are useful for awareness, not for payload truth.
