A.15.8:6.3 - Equipped performer in a present WorkPlan

Situation. ConcertPerformancePlan-2026-09-12 is one exact present U.WorkPlan. Its declaration-local content names a musician and a robotic prosthesis controller as intended performers for a proposed performance after device replacement. It also names an instrument, cue source, power support, control link, and allowed latency. None of this content is a future Work occurrence or obtaining assignment.

Probe. The current plan proposes a rehearsal under changed latency and a degraded visual-cue condition. Its material, timing, control, threshold, and stop rules are taken from the applicable music-performance, robotics, human-factors, and safety Methods. If the rehearsal occurs, first recover each actual performer through A.13 and admit the actual Work independently under A.15.1. Add F.6 only if the receiving rehearsal account also consumes precise assignment-bound attribution; missing or failed F.6 leaves the rehearsal Work intact.

Observation and result. Current evidence does not support recovery after cue loss within the required timing window. The WorkPlan-focused account names the intended performers, support and control relations, return condition, uncertainty, and the planned probe. It returns a plan repair: restore a redundant cue/control relation or narrow the supported configuration. Capability claims for the musician, device, or any independently admitted whole stay separate.

What changed. Repair the proposed sensing, control, cue, or recovery relation before declaring entry readiness; do not infer one timeless capability holder.
