  "case_id": "CASE-DZWT",
  "cues": {
    "tonal_stability": {
      "score": 4,
      "evidence_ids": ["E015", "E016", "E017"],
      "reason": "Observed: the candidate begins with octave D, followed by F-sharp and renewed D-major material. Inference: the home tonic is structurally stable at the return."
    },
    "thematic_correspondence": {
      "score": 4,
      "evidence_ids": ["E001", "E002", "E003", "E004", "E005", "E006", "E015", "E016", "E017", "E018", "E019", "E020"],
      "reason": "Observed: six candidate measures reproduce the opening's pitches, rhythms, voices, registers, and initial dynamic. Inference: this is an extensive, exact opening-theme return."
    },
    "preparation_strength": {
      "score": 4,
      "evidence_ids": ["E012", "E013", "E014", "E015"],
      "reason": "Observed: prolonged A-C-sharp-G dominant-seventh harmony and an upper G-sharp precede the downbeat D arrival. Inference: the candidate receives strong dominant and voice-leading preparation."
    },
    "proportional_location": {
      "score": 3,
      "evidence_ids": ["E015"],
      "reason": "Observed: the candidate occurs 159 of 390 quarter notes into the second part, about 40.8%. Inference: this is substantially compatible with a recapitulatory division, though full-form proportions are unavailable."
    },
    "rhetorical_emphasis": {
      "score": 3,
      "evidence_ids": ["E014", "E015"],
      "reason": "Observed: active preceding figuration yields to a downbeat octave-D texture and a renewed piano marking matching the opening. Inference: the textural and dynamic reset creates a clear, restrained arrival."
    },
    "rotational_continuation": {
      "score": 4,
      "evidence_ids": ["E007", "E008", "E021", "E022"],
      "reason": "Observed: continuation measures reproduce the corresponding opening measures, including pitches, rhythms, rests, register, and articulations. Inference: sustained rotational correspondence strongly favors recapitulation over continued development."
    }

  "status_distribution": {
    "not_recapitulation": 0.002,

  "suspected_recognition": {

  "case_note": "The candidate combines a prepared home-tonic arrival with an exact opening-theme return and continued rotational correspondence, strongly supporting tonic double return."
}

## Limitations

The dossier supplies complete symbolic data only for selected windows, not the entire movement or a full formal map; first-part duration and later recapitulatory outcomes are missing. This limits proportional and large-scale tonal assessment. Analytical uncertainty remains in interpreting the restrained piano arrival and whether the preceding dominant prolongation constitutes a decisive formal retransition.
