# Analysis result

The candidate return in this dossier is a clear tonic double return: the opening theme comes back note-for-note in the home key of D major over a tonic bass, after a sustained dominant retransition, and the continuation proceeds as a recapitulation toward tonic closure.

## Run metadata

- Analyst model: claude-fable-5 (Claude Fable 5, Anthropic), as reported by the operating environment.
- Sampling settings: unknown (not observable).
- Tools and external data: available in the environment but not used; analysis relied solely on the embedded dossier per the access boundary.

## Limitations

Missing dossier evidence: no tempo, instrumentation, or full-movement context; windows are excerpts, so material between windows (including any earlier false returns) is unobservable, limiting the proportional and preparation judgments. No dynamics appear in the pre-candidate window, so preparation is assessed from harmony alone. Analytical uncertainty: proportional placement at 41% of the second part is only weakly diagnostic, and harmonic labels (V7 from sustained A–C#–G) are inferred from pitch content without figured verification. The reported style-level familiarity was not used as evidence.
