Data and cleanup inventory

Rules were authored as transposable theory relationships under the repository license. Inspection of the four solos motivated the repair; provenance states that openly. No reference phrases, bar recipes, fingerprints, aggregate distributions or fitted weights were stored.

Schema 1 gains required gesture fields checked by the loader. Composition version: joint-arrivals-2. Runtime score/notation schemas are unchanged. No accompaniment vocabulary or role policy changed. Independent positive/negative tests do not read targets. Optional transfer fixtures remain outside production data.
