    "reason": "The distinctive 6/8 opening—high D dropping an octave and descending stepwise, followed by imitative broken-triad entries—matches K. 576's first movement. Its exact tonic return at E015 supports a sonata-form recapitulation."

## Limitations

Identification is inferred solely from symbolic pitches, rhythms, texture, form, and the encoded tonic. No score, recording, title metadata, or external catalogue was consulted. Movement marking and catalogue attribution remain subject to transcription or normalization error.
