lookforward monitor: a specialized optronic circuit containing a signaling microwormhole or temporal tangle channel from the near future. (The precise time period depends on the application, and has been configured for periods as short as one micropulse and as long as a full hour.) The function of the lookforward monitor is to receive a continuous input signal from the future and generate an output signal if the input signal ceases or otherwise departs nominal.
retroveto: Triggered by a lookforward monitor, a retroveto is a safety procedure invoked automatically, whether to cancel a user-initiated action which would have caused a disaster within the time range of the lookforward monitor (detectable since changes to a worldline propagate instantaneously along that worldline in terms of its internal time), or to trigger preemptive emergency procedures, for example a reactor scram.
retroabort: In spaceflight and other transportation jargon, a mission abort triggered by flight computers in response to an abort signal from a lookforward monitor indicating catastrophic vehicle failure.
Extensive iterative development of the design concepts involved in retroabort technology along with related families of devices such as UNMOVED MONAD and the moiraean alarm ultimately led to the development of refined shielding technologies, most notably the probability unseller.
