# Identification probe result

I examined the dossier's four windows before answering. The opening (W1) presents a forte unison-octave theme in D major, 6/8, built on tonic–dominant "horn fifths" (D–A–D–F#–D–F# over octave doubling, E001–E002), repeated-note dominant calls with a trilled C# turn (E003), and answering trill figures — a textbook Classical "hunt" topic. W2 shows a dominant preparation with a sustained A5 over a chromatically ascending inner voice (B♭–B, C–C#, D–D#, E–F#, E010–E013) and a scalar retransition, and W3 is a literal return of the opening theme inside the second repeated half — a rounded-binary/sonata return. The two-voice octave texture and figuration read as solo keyboard.

This profile is consistent with many mid-to-late eighteenth-century D major 6/8 hunt-style movements (Haydn and Mozart keyboard sonatas and rondos, hunt finales). Several plausible candidates came to mind, but none matched the dossier note-for-note against what I can verify from memory, and no candidate stood out enough to assert a specific work without risking a false identification.

## Limitations

Identification was attempted from memory only, per the access boundary; no scores or databases were consulted. The hunt topic, key, meter, and form are shared by many Classical works, so stylistic convergence is high and note-level verification against candidate scores was impossible. The window-relative measure numbering and absence of tempo, instrumentation, and title metadata further limit discrimination. A confident specific identification would require exact-match comparison against reference encodings, which this probe deliberately excludes.
