# Identification probe result

Working only from the embedded dossier, I analyzed the symbolic evidence: a D major movement in 4/4 (two sharps throughout), opening with an anacrusis figure — A5 with a grace-note B5, then G5–F#5 sixteenths — resolving to a melody over an Alberti-style eighth-note accompaniment (D–F#–A–F# patterns in V03). The texture is two-hand keyboard idiom: singing right-hand line with sixteenth-note scalar runs featuring chromatic passing tones (G#, D#, A#), parallel thirds, repeated-chord dominant prolongation over an A pedal with borrowed B-flat/F-natural color before the return, and light staccato cadential figures. The `candidate_return` metadata places a literal restatement of the opening theme 120 quarter notes into a 408-quarter-note second part, consistent with a sonata-form recapitulation in a rounded binary/sonata movement.

All of this points clearly to a Classical-era keyboard sonata movement in the Mozart/Haydn/early-Clementi idiom, likely an Allegro first movement. However, the specific melodic incipit (A pickup with grace note, G–F# sixteenths, landing E–D–D with a leap to B) does not match any single work I can name with confidence from the dossier evidence alone. I considered several D major Mozart and Haydn sonata movements, but none matched well enough to assert a specific identification, so I am reporting a style-only resemblance rather than presenting a weak guess as recognition.

## Limitations

Judgment rests entirely on symbolic features in the dossier; no audio, title, tempo, or dynamics were available (directions arrays are empty). The window-relative measure numbering obscures absolute position. My inability to name a specific work is not evidence the piece is obscure — recall from symbolic notation alone is much weaker than from sound. The confidence value reflects certainty in the stylistic attribution (Classical-era keyboard sonata idiom), not in any particular composer or catalogue entry.
