    "tonal_stability": {
      "score": 4,
      "evidence_ids": ["E015", "E016", "E017"],
      "reason": "Observed: the candidate begins with octave D, followed by F-sharp and further D-major material. Inference: the home tonic is strongly and structurally established at the return."
    },
    "thematic_correspondence": {
      "score": 4,
      "evidence_ids": ["E001", "E002", "E003", "E004", "E005", "E006", "E015", "E016", "E017", "E018", "E019", "E020"],
      "reason": "Observed: the candidate reproduces the opening’s pitches, rhythms, voices, register, and initial piano dynamic for six measures. Inference: this is an extensive, exact opening-theme return."
    },
    "preparation_strength": {
      "score": 4,
      "evidence_ids": ["E012", "E013", "E014", "E015"],
      "reason": "Observed: a prolonged A–C-sharp–G sonority and descending upper line precede the arrival on D. Inference: sustained dominant tension and directed voice-leading strongly prepare the tonic return."
    },
    "proportional_location": {
      "score": 3,
      "evidence_ids": ["E015"],
      "reason": "Observed: the candidate occurs 159 of 390 quarter notes into the second part, about 41 percent. Inference: this substantially supports a plausible recapitulatory division, though broader formal proportions are unavailable."
    },
    "rhetorical_emphasis": {
      "score": 3,
      "evidence_ids": ["E014", "E015"],
      "reason": "Observed: the high, active preceding line gives way to low octave D, restored opening texture, longer values, and piano. Inference: the contrast marks a clear arrival, although no accent or strong dynamic intensification appears."
    },
    "rotational_continuation": {
      "score": 4,
      "evidence_ids": ["E007", "E008", "E021", "E022", "E023", "E024", "E025", "E026"],
      "reason": "Observed: continuation measures initially reproduce opening measures 7–8 exactly, then retain closely related tonic-oriented material. Inference: the post-candidate behavior strongly confirms continued rotation rather than developmental sequencing."

## Limitations

The dossier supplies complete symbolic data only for selected windows, not the entire movement’s thematic and tonal course or first-part duration. Thus global proportional and formal-boundary judgments remain less secure than the locally exact comparisons. Analytical uncertainty chiefly concerns whether the return’s relatively early second-part location could serve another formal function; the tonic arrival, thematic identity, and rotational continuation themselves are strongly evidenced.
