When anchorMs is not provided (always in production), the schedule computed nextRunAtMs as nowMs, causing jobs to fire immediately and repeatedly instead of at the configured interval. - Change nowMs <= anchor to nowMs < anchor to prevent early return - Add Math.max(1, ...) to ensure steps is always at least 1 - Add test for anchorMs not provided case
