This mismatch caused the queue script to always see the context as "missing" and never attempt a merge. Fix: update REQUIRED_CONTEXTS to the live API-reported context names (all Python 3.x matrix entries) and restore the SOP checklist gate context (dropped when the workflow overrode the script defaults).
