Only create started the per-workspace monitor, and only on its job path, so the stop -> update -> resume flow the update skill requires left no monitor. resume now calls start_watchdog with the control root as workdir (as create does since #21 A8, also for a worktree session) after the row is written, on both the already-running and the spawn path. MAM_NO_SUBSCRIBER_DAEMON=1 starts none; a failure warns and does not fail the resume. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
