    "reason": "The D-major 6/8 piano texture, upbeat A, octave-unison tonic arpeggiation, characteristic trilled cadential figures, and exact later return of the opening theme strongly match the finale of Mozart's K. 311."

## Limitations

The identification is inferred solely from symbolic pitch, rhythm, texture, and formal-return evidence. No title, instrumentation label, tempo text, or external source was available, so the catalogue attribution remains a high-confidence candidate rather than independently verified identification.
