    "tonal_stability": {
      "score": 0,
      "evidence_ids": ["E015", "E016", "E017", "E018"],
      "reason": "Observed: E015 begins with sustained G over G-D-B-D, and E016-E018 retain G-centered, C-natural harmony. Inference: home D is not structurally stable at the candidate."
    },
    "thematic_correspondence": {
      "score": 4,

      "reason": "Observed: E015-E022 reproduce E001-E008's rhythms, melody, accompaniment, rests, and trill, consistently transposed from D to G. Inference: this is a complete opening-theme return."
    },
    "preparation_strength": {
      "score": 4,
      "evidence_ids": ["E014", "E015"],
      "reason": "Observed: E014 sustains D-A-C beneath an ascending line ending F-sharp, immediately resolving to G in E015. Inference: an extended dominant-seventh preparation strongly targets the candidate's G arrival."
    },
    "proportional_location": {
      "score": 3,
      "evidence_ids": [],
      "reason": "Observed: the candidate occurs 52 of 180 quarter-notes into the second part, or 28.9%. Inference: early, but compatible with a relatively short development and extended recapitulation."
    },
    "rhetorical_emphasis": {
      "score": 3,
      "evidence_ids": ["E014", "E015"],
      "reason": "Observed: E014's continuous scalar sixteenths give way on E015's downbeat to the opening's broad two-voice texture and sustained high melody; no dynamics or articulations mark it. Inference: the textural arrival is substantial but unaccented."
    },
    "rotational_continuation": {
      "score": 4,

      "reason": "Observed: after E015-E020, E021-E022 continue the exact transposed correspondence with E007-E008; E023-E026 proceed beyond that block toward D-centered sonorities. Inference: continuation favors recapitulatory rotation over ongoing development."

## Limitations

Missing dossier evidence includes the complete music outside the supplied windows and any performed sound, limiting assessment of broader formal balance and audible emphasis. Analytical uncertainty remains over whether the early G return could function as an unusually extensive false return, though its complete thematic rotation and continuation make that reading unlikely.
