Inputs can be unsorted. Zero durations are milestones. Use provided durations; do not infer missing estimates. Report project duration, critical tasks and the illustrative longest chain. Explain that offsets start at zero and resources, calendars and lags are not modeled. The widget edits durations and exports the complete schedule. Downloads expire in about one hour. Do not use for calendar scheduling or Gantt charts.\n"
