Audit ahead of the README/doc.go work (issue #3): - number.go: Min, MinFloat32, MinFloat64 all said "less than or equal to a given maximum" -- copy-pasted from the Max family. They check the minimum. Fixed. - chars_test.go: ExampleExceptChars called Chars, not ExceptChars, so it never exercised the function it documents. - chars.go: "does not contain disallowed characters" was circular. - in.go: NotIn's parameter was named "allow"; renamed to "disallow". - length.go: note that length is bytes (len), not runes -- the "%d characters" messages imply otherwise. - url.go: spell out that ParseRequestURI wants an absolute URL or path. - uuid.go: note lowercase-hex only, version/variant not checked. - error.go: explain Err (the match-anything sentinel), how Error() formats with Data, and what With does. all.go: point at Collect. Comments only; no behaviour change. go vet + go test ./... pass. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
