The analyzer accepts one MP3 or WAV only in the visitor's browser. The public agent service does not receive audio, analyze remote files, submit feedback, send email, create accounts, or perform purchases. Tap Tempo remains human-operated. Authentication metadata is a clearly disabled construction contract; public tools do not require authentication.
