Generate a person audience from a plain-English brief — discover the signals behind it, score them with the math visible, and compose them into an audience whose reach is measured. The build step behind /watt:audience; routes to the leaf that fits how the audience should be built. Produces a signal stack + measured reach, or a roster — never an export, never contact data. Not a user command — /watt:audience is the front door. Use when a build-shaped ask arrives — "build me an audience of …", "I need about N people who …", "the highest-intent people in-market for X", "where do these people cluster", "a lead list of in-market companies", "match my customer list / build from my customers" — or when a /watt:explore signal pool is ready to become an audience.
