  "cues": {
    "tonal_stability": {
      "score": 4,
      "evidence_ids": ["E016"],
      "reason": "Observed: the candidate begins with D in both voices and outlines D–A–D–F-sharp–D–F-sharp. Inference: this immediately and structurally establishes the home tonic."
    },
    "thematic_correspondence": {
      "score": 4,
      "evidence_ids": ["E002", "E003", "E004", "E005", "E006", "E007", "E016", "E017", "E018", "E019", "E020", "E021"],
      "reason": "Observed: E016–E021 reproduce the pitches, rhythms, voices, and register of E002–E007, with a minor articulation difference. Inference: this is an extensive, essentially exact opening-theme return."
    },

      "evidence_ids": ["E010", "E011", "E012", "E013", "E014", "E015", "E016"],
      "reason": "Observed: sustained A spans E010–E013; E014–E015 add forte scalar descent and a final A–E dominant dyad before D at E016. Inference: dominant and rhetorical preparation is strong."
    },
    "proportional_location": {
      "score": 3,
      "evidence_ids": ["E016"],
      "reason": "Observed: E016 occurs 120.5 quarter-notes into a 306.5-quarter-note second part, about 39%. Inference: this is compatible with a development-to-recapitulation division, though location alone is not decisive."
    },
    "rhetorical_emphasis": {
      "score": 3,
      "evidence_ids": ["E014", "E015", "E016"],
      "reason": "Observed: forte rapid descent and a low forte A precede E016’s registral reset and homorhythmic octave texture; no new candidate dynamic appears. Inference: the arrival is substantially emphasized."
    },
    "rotational_continuation": {
      "score": 4,
      "evidence_ids": ["E002", "E003", "E004", "E005", "E006", "E007", "E008", "E009", "E016", "E017", "E018", "E019", "E020", "E021", "E022", "E023"],
      "reason": "Observed: E016–E023 reproduce E002–E009 in order with only minor articulation or duration variation. Inference: sustained ordered continuation strongly indicates recapitulation rather than sequence or continued development."

## Limitations

The dossier provides symbolic excerpts rather than a complete formal map, so proportional interpretation lacks exposition length and alternative formal landmarks. Dynamics and articulation are complete but sparse, limiting rhetorical assessment. Analytical uncertainty remains about whether the preceding passage constitutes a closed cadence, although its dominant function and the subsequent tonic thematic return are clear.
