Case study
Documents had to be moved between student records before a fixed date, after which the originals would be gone. A common plan is to migrate, check a sample and fix complaints as they arrive. This one was verified record by record first.
Document records are easy to underestimate. Each one ties a file to a student, a type, a status and a date, and each of those links has to survive the move. A missing transcript or a document attached to the wrong student is found at the worst possible moment, usually by the student.
Here the documents had to be moved from one set of student records to another ahead of a cleanup that would remove the originals. There was a deadline, and no second chance once it passed.
The migration was rehearsed before the production run. The verification was a separate step from the migration, with its own record of what it compared and what it found.
The production migration was delivered on deadline with zero defects, and the client signed off on a record-by-record verification instead of a sample.
“We checked a sample” means “we do not know about the rest.” If the tooling can compare a hundred records it can compare all of them. Insist that it does.

Full-time architect role
A check-only report is read and approved first; then one command corrects financial aid records for a whole student population, can be run again safely, and leaves before-and-after evidence for every student.
Full-time architect role
A second AI agent independently re-checks AI-assisted migration work against the source systems and writes the audit trail, in place of spot checks by hand.
Consulting engagement
A timed job sometimes lost a race with the email scheduler, so students got an invitation with no link. Now the link is saved as soon as the record is.
