ALE contributor music task, music-quintet-v7-20261009. Only workspace/ is solver-visible. Hidden reference/truth/labels/builders/evaluator and actual execution evidence are contributor-only. Source comprises three complete consecutive movements from the verified primary MusicNet archive, concatenated with disclosed four-second gaps. Author reference is annotation-assisted, velocities constructed; professional musical QC/calibration, expert elapsed time and final contributor/source rights confirmation remain pending. This is standalone local evaluation, not executed remote ALE integration or official acceptance.
Acquire REAPER 7.82/Linux, x42 General MIDI Synth 0.6.4 and recorded dependencies. For reproduction run builders/rebuild.py --package PACKAGE --build-dir EMPTY_BUILD; use its actual new truth/reference/native_health.json for evaluation. Large WAV/workspace storage may be remote; private native configuration is explicitly local. Software hashes and the actual reference control bind health; never invent a success flag.
