A file you can account for, line by line.

A job opens with criteria that can be counted, not adjectives. Gaps are measured and reported, not interpolated. Coverage is reported as three numbers: matched, unmatched, and unverifiable.

Retention position

Stating how long we keep what was built, and what happens to it afterwards.

Validation

Checking structure and reachability before a file is used, not after.

Decay review

Identifying the records that have stopped being current, and how many of them there are.

Start with one segment rather than the whole plan, and see whether it holds.
