Analytics
Operational rates, each beside the counts it came from (09 §3.12).
Every rate arrives with its denominator
A rate with no cohort and no period is not a measurement. Matching success is counted over all qualified requests, including the ones nobody was offered because no business could take them — a market with no supply lowers the rate rather than disappearing from it.
Name a cohort and a period to read its rates. Nothing has been asked for yet.

analytics:readExports use authorised projections with fixed columns, never a column picker: report buyers are never exported as a marketing or contractor list (09 §11).
