Key decisions covered in this article.

Recreate the duplicate

Test a successful purchase, a reload, and a retry after interruption in a permitted test path. Check whether two implementations report the same completed event or whether the event fires on page load.

Repair and annotate

Choose one valid source and apply a stable event identifier where supported. Verify the event occurs once, then mark the affected reporting window so older comparisons do not silently include duplicates.
