# Identification probe result

## Run metadata

- Analyst model: Claude (claude-fable-5)
- Case ID: CASE-8JQJ
- Date of run: 2026-07-19
- Condition: symbolic dossier only; no external lookup performed, per the access boundary.

The evidence supports a stylistic characterization but not a specific identification. The dossier describes a two-voice keyboard piece in D major, 3/4 meter, in rounded binary form: window W1 gives an eight-measure opening period (descending eighth-note run G5–F#5–E5–D5–C#5 over half-note bass dyads, inverted mordents on F#4 and E4, a tied C♮5 with trill introducing chromaticism toward B minor), W2 shows a sequential retransition with a sextuplet descent and a spelled B#2 in the bass, and W3 (the candidate return, 72 of 141 quarter notes into the second part) restates the opening material nearly verbatim before diverging chromatically (A#, B#, G# bass). W4 adds broken-chord sixteenth figuration suggesting a varied continuation. This is idiomatic mid-eighteenth-century galant/Baroque keyboard writing — a minuet-type dance movement — but the material is generic enough within that repertoire that I cannot responsibly name a composer or work from the notation alone.

## Limitations

Analysis relies solely on the four excerpted windows; connecting material and the movement's full second half are unavailable, so form-level cues (e.g., paired dances, variation sets) cannot be checked. Symbolic encoding omits tempo, instrument, and title metadata that normally anchor identification. Minuet-style two-voice writing in D major is extremely common across 1700–1780 keyboard repertoire, so the absence of a distinctive matched incipit keeps confidence low; the style-only judgment could be overturned by a single corroborating measure from an external score, which the probe boundary forbids consulting.
