The boring part, taken seriously.

Nothing is sourced until the shape of the audience is settled. Fields are filled only where a source supports them. Every claim the file makes about itself can be checked against it.

Currency handling

Stating the unit and basis for any monetary field instead of leaving it implied.

Scope agreement

Turning a written requirement into countable criteria, and confirming the size before any records are assembled.

Null discipline

Keeping empty and unknown distinct, so a filter can tell the difference.

If you already know the universe you want, we can confirm it in a day or so.
