# Evaluation and validity
|
|
|
|
The active final selector remains `scoring.musical` / `MusicalEvaluation`, version `joint-musical-1`. Each phrase score is its evaluation total; the complete solo uses duration-weighted completed phrase evaluations. This revision changes construction coverage, not the final weights.

Reports expose raw values, denominators, weights, contributions, total and validity. Identity, expression completion, physical domain and protected holds are hard contracts, not duplicate resemblance costs. Early retrieval estimates remain separate.
|
|
|
|
Planned arrival spans have arrival activity semantics; they need no attack on every held beat. Silence cannot exploit a missing register value. Ties merge before harmonic duration/attack evaluation; repeated attacks cannot fulfill a hold.
|
|
|
|
Joint arrival/color/approach candidates exist before route search. An approach into future harmony requires the exact shared anticipation target. Mapped upper neighbors must actually belong to the collection. The stable minor-sixth policy is bounded by harmony/function/duration and does not legalize unrelated notes.
|
|
|
|
Selected ordinary arrival pitches and tails are also protected through refinement; ordinary computational endpoints remain provisional. Disabling expressions removes joint expression proposals and local ornaments and may choose another valid complete phrase. It does not mean deleting exceptional notes from a winner.

|
|
|
Reference recognition, proposed candidate, validity, retention, selected use and exact event matching are reported separately. The optional comparison has no scoring-return channel. Exact agreement is not a production loss function.
