How the scheduler evaluates the status of a condition

The condition status can be any of the following values:
U (Undefined)
When the rule cannot be evaluated yet.
T (True)
If the rule is set to AND
When ALL condition dependencies are true.
If the rule is set to OR (at least n condition dependencies must be true)
When at least n condition dependencies are true.
F (False)
If the rule is set to AND
When at least one condition dependency is false.
If the rule is set to OR (at least n condition dependencies must be true)
When at least n condition dependencies cannot be true.
