How a tool gets listed
- Open a PR on the spec repo adding a row to /registry/tools.json.
- Provide URL + brief description + expected status.
- We run the audit: publish a draw on your tool, copy the hash, verify by re-running against your published canonical input.
- If the hash + canonical reproduce the same winner, you're marked VGP v1.0.
