The Economic Studio's evidence baseline for one published business and one published supply category: the business's public category declaration, and the official CanadaBuys notices whose requested categories overlap it.

Read-only and no-store. The body carries exactly two identifiers; economic assumptions such as price, cost or volume are refused, because the Studio computes with them in the browser and they never reach the server. The response is the standard envelope: meta.dataStatus and meta.evidence state at the resource level whether a baseline was bound. Inside data, baseline.state, records[].reference.truthState and the limitations carry the detail. Category overlap is compatibility only. It establishes no eligibility, demand, award likelihood or supplier relationship, and an empty overlap is not evidence of absent demand.
