Validation Canvas

Produce a rigorous Lean Canvas + Value Proposition Canvas combined artifact from founder inputs. Each block is a stress-tested belief, not a template field. The canvas is the primary deliverable; the interview that produces it is where most of the value lives. The job here is declarative — what do we believe? — and is the upstream half of validation. The downstream half (what have we proven?) is owned by the riskiest-assumption-test skill that runs after this one.
