Read who a market is, starting from a plain-English brief — discover → pivot → read. The discovery-first way into audience-analyze, behind /watt:audience; size is an output, never a target. Aggregates only — never individual records, never an export. Not a user command. Use when a read-shaped ask arrives with a brief and no signals yet — "who's in the market for X", "profile this audience", "an audience profile for my client".
