Every scheduled Update run since 2026-10-31 failed with 'Missing required argument: source': --agent takes several values and swallowed the source that followed it. update.sh now passes the source first. test_update.py had pinned the source as the last argument and so encoded the bug; it now requires the source right after add and claude-code as the only agent (negative control against the old order fails).
