Hold the README and CONTRIBUTING to the repository with a test #69

Parent

#21

What to build

A test that holds the README and CONTRIBUTING.md to the repository, so the first documents a reader opens cannot quietly drift from it.

Prose goes stale silently: a renamed script, a coverage threshold that moved, a pinned Node version that changed. Each of those reads exactly as well wrong as right, and a new contributor follows the wrong one.

Claims worth holding:

• Every npm script the documents tell a reader to run exists in package.json.
• The coverage numbers the documents quote match the thresholds in the Vitest config.
• The Node version the documents tell a contributor to install matches .nvmrc.
• Every path the documents name as a file or directory exists.

The link gate already checks that relative links and heading anchors resolve, so this test covers the claims it cannot see: names, numbers and versions.

Acceptance criteria

• Renaming a script the README names fails the test, and the failure names the document and the claim.
• Changing a coverage threshold without updating the documents fails it.
• Changing the pinned Node version without updating the documents fails it.
• A clean tree passes, and the test has claims to check rather than passing over an empty list.
