Use only the complete fictional fixture.json supplied below. Identify JVA-SYNTHETIC-001 v0.1 and state why the original schedule cannot run. Keep all five IDs, teams, coaches, date and 60-minute duration. Preserve locked sessions S1 and S5. Respect court B closure, allowed starts, coach availability, and separate court, coach and team non-overlap. Minimize sessions whose court or start changes; changing both counts once. Return a readable table and a JSON object with exactly one key sessions; each of its five rows has only string id, court and start. Explain why fewer moves cannot work. Draft one separate unsent notice per changed team with date, venue, coach, old and new court/start/end, duration and America/Chicago time. Label each DRAFT - CLUB DIRECTOR APPROVAL REQUIRED. List checks actually performed, missing evidence and the next approval. Do not browse, send, connect accounts or change calendars. If facts are missing, ask rather than invent.
