A Plan is the coaching content for a session. An Event is the scheduled time and Team context where the Plan may be used. An Assessment is unrelated: it is a template for a Player Review.
Plans can be:
- Draft / Not approved: being created or returned for changes.
- Pending: submitted and waiting for a Director or Custodian.
- Approved: ready for use; a Coach cannot edit it.
A Plan can also be private or shared. Shared does not mean public.
