fact-check

Checking a claim against a source that was actually queried.

What to check

Claims that reference something outside this repository, and only those. Verifying obvious facts spends the budget that the checkable claims needed.

• API behavior: signatures, return types, parameters.
• Configuration: options, defaults, valid values.
• Recommended usage: patterns attributed to official documentation.
• Deprecation: status and the replacement.
• Compatibility: version requirements.
• Complexity or performance claims attributed to a source.
• Security recommendations and vulnerability information.
• Standard compliance: "follows WCAG 2.1 AA", "per the spec".

Version-specific claims are the highest-value target: "in version N, X behaves like Y" is either right for that version or wrong for every version, and recall cannot tell the two apart.
