One definition, applied across the book — the farmer or customer answers from existing records instead of building a bespoke pack each time. That reuse is what slashes cost-to-serve.

An outstanding item is named precisely and chased within scope — never assumed negative, never converted into a rating.

What the grantor sees · the consent preview

the requester's auditable receipt
Before granting
the farmer sees each requirement item, exactly which records would satisfy it, and what the derivative excludes (identity, location, economics)
On granting
a dated, purpose-limited receipt is kept on both sides — "you never told us" disputes end at that receipt
Afterwards
access renews, narrows, expires or ends at the grantor's choice · every view is logged

Requirement rules: the requester inspects fulfilment status, never unauthorised private data. Requirements are purpose-limited and reusable; answers come from existing records; missing items are chased, not scored.
