Scoped, matched, and written down.

The brief is the specification, and it is written before the build. Duplicates come out before the total is reported, never after. Sometimes the honest finding is that no such audience exists, and that gets said.

Phone formatting

Rendering numbers in a consistent international form, with the original retained.

Specification drafting

Writing down the field list, definitions and rules, so the same build can be repeated later.

Legal-entity grouping

Deciding whether branches roll up to one parent or stand alone, and applying it consistently.

Ask for the limits as well as the total; both are available.
