Term	Kind	Topic	What it is

Exception Register Waiver Management, Control Deviation Record, Risk Acceptance Log	practice	Exception & Waiver Management	A recorded, owned, time-bounded set of approved deviations from a control - which is what makes a control survivable, and whose aggregate is the best available evidence about whether the control fits reality.
Time-Boxed Waiver	practice	Exception & Waiver Management	An approved deviation from a standard that carries an owner, a justification, a compensating control and an expiry date after which it is reconsidered.
Waiver Expiry Time-Bounded Exception, Expiring Risk Acceptance	practice	Exception & Waiver Management	A mandatory end date on every exception to a standard, so that continuing the exception is an active decision rather than the default.
