Believers
Classify interview participants as Believer / Neutral / Infidel using the earlyvangelist test. Track believer density. Surface PMF-mirage when too many users are tire-kickers.

Interview
Interview user to clarify any topic - exploring codebase, investigating issues, planning features, understanding requirements, or drilling into plans. Socratic questioning to uncover details.
Pivot
Walk through the 10 canonical pivot types using brain evidence to inform direction. Forces explicit kill criteria for the previous hypothesis before allowing a pivot. Logs to brain/pivots.md with full reasoning.
Pmf Check
Triangulate Product-Market Fit signal from three independent sources — disappointment survey, retention cohorts, believer density. Returns Strong PMF / PMF / Pre-PMF / PMF Mirage. The triangulation is what's hard to fake.
Roleplay
Practice an interview script against a deliberately adversarial AI customer who pushes back, demands specifics, and refuses to validate vague claims. Outputs to brain/practice/ (separate namespace from real interviews). Pre-flight requires at least 1 real interview to prevent roleplay-as-substitute.
