{
  "schema_version": "2.1.0",
  "analyst_model": "GPT-5",
  "case_id": "CASE-6U43",
  "identification": {
    "recognition_level": "specific_candidate",
    "composer": "Johann Sebastian Bach",
    "work": "Partita No. 5 in G major, BWV 829",
    "movement": "VII. Gigue",
    "confidence": 0.91,
    "evidence_ids": ["E001", "E002", "E003", "E015", "E016", "E021"],
    "reason": "The 6/8 two-part texture, distinctive octave-drop and descending-scale subject, sequential contrapuntal continuation, and exact tonic return of the opening subject at E015 strongly match the Gigue from BWV 829 after tonic normalization."
  }
}
```

## Limitations

The dossier normalizes the tonic to D and omits title, instrumentation, tempo, and source metadata. Identification therefore rests on the subject’s intervallic-rhythmic profile, contrapuntal design, and formal return. Closely related Baroque gigues could imitate these traits, so the catalogue attribution is highly confident but not certain.
