Column standards
Clean enough to use, measured enough to trust.
Requirements are read back as filters before anything is run. Categories are checked against the underlying description, not the label attached upstream. What cannot be evidenced is left out and listed.
Whitespace discipline
Removing the invisible differences that make two identical values compare as different.
Consent state
Carrying the permission status through to delivery instead of dropping it at export.
Change-only refresh
On a repeat build, reporting what actually moved instead of re-delivering the whole file.
