    Validate a startup idea with the Diamond graph — a decision contract frozen before any evidence exists, parallel blind researchers (customer / competitor / distribution / economics / risk), an adversarial skeptic, an independent merge, and a human gate. Use when someone says "should I build X", shares a new idea, asks whether an idea is worth testing, or wants market, customer, competitor or go-to-market research. Produces a one-page pursue / pause / kill recommendation with a graded evidence trail in ideas/<slug>/.
