The proposal is technically simple and experimentally bounded, but actual masking prevalence, stakeholder demand, comparative efficacy, stylistic transfer, and distinctiveness remain unsupported.","adopter_authorizer":"The composer or rights-holding creator and authorized arranger, together with the ensemble artistic lead; performers advise on cue reliability and playability, while researchers require participant consent and cannot redefine aesthetic intent.","scores":{"meaningful_impact":{"score":3,"rationale":"If the stated masking occurs, clearer themes, transitions, and hierarchy could materially improve the intended musical experience and performer coordination. No evidence establishes how often the problem occurs or how consequential it is across works."},"stakeholder_pull":{"score":2,"rationale":"The packet identifies plausible affected parties and consequences but supplies no requests, commitments, observed complaints, adoption interest, or other evidence of demand from creators, ensembles, performers, or listeners."},"incremental_advantage":{"score":3,"rationale":"Protected omission makes a testable change beyond conventional balance, articulation, dynamics, timbre, or register adjustments, and the nearest-rival comparison can isolate that increment.

Its relationship to established arranging, orchestration, use of silence, and music-cognition practice is unresolved."},"technical_implementability":{"score":5,"rationale":"A reversible alternate version of one short excerpt can be prepared, rehearsed, recorded, counterbalanced, evaluated, and rolled back using ordinary scoring, performance, and listening-study methods."},"adoption_authority_feasibility":{"score":4,"rationale":"The proposal clearly identifies the required creative and ensemble authorities, performer input, participant consent, excluded actions, and rollback conditions. Feasibility depends on obtaining authorization for a suitable work and respecting any cultural governance."},"evidence_readiness":{"score":4,"rationale":"The packet specifies an observable baseline, nearest rival, short test unit, outcome measures, counterbalanced comparison, separate problem and intervention falsifiers, and halt criteria. It lacks an authorized excerpt, measurement thresholds, and outcome data."},"safety_net_benefit":{"score":4,"rationale":"Changes are excerpt-bounded and reversible, with explicit restoration triggers for cue loss, misinterpreted silence, reduced coherence, impaired form, or conflict with creator intent.
