## Assumptions


## Possible explanations


## Missing or rejected evidence

- {"code":"unconfirmed\_corrections","severity":"warning","message":"Unconfirmed corrections are preserved as proposals and are not applied to the imported record.","evidence":\[{"filename":"synthetic-handoff.json","record\_index":4,"source\_row":5,"source\_page":null,"source\_id":null}\]}

## Next measurements or inspections

- Review the preview with the responsible grower. Record the author, assignee and completion evidence before treating a task as verified.

## Sources and correction history


The companion report.json retains the complete source mappings, normalized/original values, evidence row references, corrections, and all flags. No sample records substitute for failed uploads.
