      "score": 0,
      "evidence_ids": ["E015", "E016", "E017", "E018"],
      "reason": "Observed: the candidate begins with a G-major sonority and sustains G-centered material, while home-tonic D lacks bass-root confirmation. Inference: the home tonic is not structurally stable at the return."

      "reason": "Observed: melody, rhythm, accompaniment, rests, and trill correspond closely across four measures, transposed from D to G. Inference: this is an extensive, strongly identifiable return of the opening theme."
    },
    "preparation_strength": {
      "score": 4,
      "evidence_ids": ["E014", "E015"],
      "reason": "Observed: a D–A–C dominant-seventh foundation and rising line ending on F-sharp precede G at the candidate downbeat. Inference: dominant preparation and leading-tone resolution strongly articulate the arrival."
    },
    "proportional_location": {
      "score": 3,
      "evidence_ids": ["E015"],
      "reason": "Observed: the candidate occurs 52 of 180 quarter-notes into the second part. Inference: a return near 29% is substantially compatible with a development-to-recapitulation division."
    },
    "rhetorical_emphasis": {
      "score": 2,
      "evidence_ids": ["E014", "E015"],
      "reason": "Observed: rapid scalar activity yields to the opening texture on a downbeat, but no dynamics, accents, or special barline mark the boundary. Inference: the arrival is perceptible but only moderately emphasized."
    },
    "rotational_continuation": {
      "score": 4,

      "reason": "Observed: the transposed correspondence continues through all remaining supplied opening measures before proceeding into new phrase material. Inference: sustained rotational continuation strongly favors recapitulation over a brief developmental quotation."

## Limitations

Missing evidence includes the unsupplied music between windows, the remainder after the continuation, and score-wide formal or tonal labels. Dynamics and directions are encoded as empty, limiting rhetorical assessment. Analytical uncertainty remains because a long transposed opening return may be either an off-tonic recapitulation or an unusually extended developmental false return; the sustained correspondence makes the former considerably more likely.
