Mailers Field

Sized before it is built.

Work is scoped against what the sources can actually support. Verification is separated from enrichment, so neither hides the other. Each delivery says how old its parts are.

Sample first

A small extract to check against before the full build, so a misread brief costs nothing.

Supply assessment

Saying plainly where the available data stops, including when it stops short of the brief.

Manual review queue

Setting aside the cases a rule cannot settle, for somebody to look at.

Bring the brief that other suppliers found difficult.
