How do Garmin planned workouts handle completion and updates?

Terra's Garmin planned-workout adapter uses Garmin's Workout Schedule endpoint.

Terra's Garmin planned-workout adapter uses Garmin's Workout Schedule endpoint.

Garmin's public Training API has no completion endpoint, so a pushed workout stays on the calendar until you DELETE it.

• Delete key: the composite scheduleID/workoutID. A peeled workoutID returns 424 Failed Dependency because the schedule entry still references the template.

• Updates: re-posting with an existing provider_workout_id and a new planned_date reschedules. Changing workout content requires delete-then-recreate.
