Review Comment: JA4 deliberately excludes GREASE extensions (as `expected_ja4()` does at line 114), so this failure message incorrectly says they are counted. Only the unknown ALPS extension affects this expected fingerprint; please make the diagnostic reflect that distinction. -- This is an automated message from the Apache Git Service.
