# 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. ## What this skill produces Always produced under the resolved canvas root (see Phase 0.0 for path resolution; default is `docs/canvas/` for solo runs, `docs/startup-kit/canvas/` when invoked via orchestrator): 1. **`validation-canvas.md`** — canonical, editable Markdown with two top-level sections: `## Lean Canvas` (nine blocks per Maurya) and `## Value Proposition Canvas` (six blocks per Osterwalder), plus a `## Stress Tests` section listing the assumptions most likely to fail. Headings are load-bearing — `pitch-deck`, `riskiest-assumption-test`, and `startup-grill` grep them by name. 2. **`validation-canvas.html`** — single self-contained HTML file rendering the Lean Canvas grid (top) and the VPC fit diagram (bottom) visually. Opens in any browser, prints cleanly to PDF, zero network dependencies. Both files carry the same content — the HTML is the visual primary; the Markdown is the source of truth founders edit as the business evolves. ## What this skill i
