What if some rows fail to upload?

Partial failures are normal and mostly harmless. What matters is that they get noticed — uploads fail quietly, and a tool that assumes success builds a change history that slowly diverges from reality.

On the next data pull, AutoPPC compares live state against what it expected. Rows that did not land are flagged and returned to the review queue. They are never counted as applied.

The same mechanism catches changes made outside AutoPPC, including by other people on your account.
