    "reason": "The distinctive 6/8 D-major opening—upbeat A followed by the octave hunting-call figure D-A-D-F-sharp-D-F-sharp—and its later exact return strongly match the first movement of Mozart’s K. 576. The chromatic developmental passage over sustained upper A further supports the identification."

## Limitations

The identification is inferred solely from symbolic pitch, rhythm, texture, ornament, and formal-return evidence. No tempo marking, title, instrumentation label, score image, or external catalogue comparison was available. Although the opening is highly distinctive, movement numbering and sonata numbering can vary by edition; the Köchel identifier is the more reliable designation.
