UUID Validator Documentation

Check whether a value is a valid UUID and identify its version and variant.

SiteIndex checks the pasted value against the canonical UUID pattern, then reads its version and variant bits to report which UUID version produced it, if any.

• Confirm a value from a database or API is a well-formed UUID.
• Identify which UUID version (v1, v4, v7, etc.) a value uses.
• Catch a malformed identifier before it causes a downstream error.
