While in the illustrated example of 
Returning to block 840, if the example instruction validator 650 determines that the retrieved instructions are not valid (e.g., block 840 returns a result of NO), the example management endpoint interface 630 provides a status update to the management endpoint 340 indicating that the instructions were rejected (block 870). In some examples, instead of informing the management endpoint 340 of the failure to validation of the instructions, control may return to block 825, where the example instruction retriever 640 may re-attempt to retrieve the instructions from the repository 134. Such re-attempts may be performed up to, for example, a threshold number of re-attempts (e.g., three re-attempts, five re-attempts, etc.) before the example management endpoint interface 630 informs the management endpoint 340 of the rejected status of the instructions (block 870).
