How to read the result
Mechanical checks catch field length, delimiters and exact repetition. Editorial flags identify text worth reading again; they are not algorithm rules.
Apple and Google Play index and display different fields. A clean draft still needs audience, keyword-demand, localization, policy and conversion review.
