+Throughout the execution of the workload, the AppWrapper controller
+monitors the number and health of the workload's Pods. It also watches
+the top-level created resources and for selected resources types
+understands how to interpret their status information. This information
+is combined to determine if a workload is unhealthy. A workload can be
+deemed *unhealthy* if any of the following conditions are true:
+   + There are a non-zero number of `Failed` Pods.
+   + It takes longer than `AdmissionGracePeriod` for the expected
+     number of Pods to reach the `Pending` state.
+   + It takes longer than the `WarmupGracePeriod` for the expected
+     number of Pods to reach the `Running` state.
+   + If a non-zero number of `Running` Pods are using resources
+     that Autopilot has tagged as `NoExecute`.
+   + The status information of a batch/v1 Job or PyTorchJob indicates
+     that it has failed.
+   + A top-level wrapped resource is externally deleted.
+
+If a workload is determined to be unhealthy by one of the first three
+Pod-level conditions above, the AppWrapper controller first waits for
+a `FailureGracePeriod` to allow the primary resource controller an
+opportunity to react and return the workload to a healthy state. The
+`FailureGracePeriod` is elided for the remaining conditions because the
+primary resource controller is not expected to take any further
+action. If the `FailureGracePeriod` passes and the workload is still
+unhealthy, the AppWrapper controller will *reset* the workload by
+deleting its resources, waiting for a `RetryPausePeriod`, and then
+creating new instances of the resources. During this retry pause, the
+AppWrapper **does not** release the workload's quota; this ensures
+that when the resources are recreated they will still have sufficient
+quota to execute.  The number of times an AppWrapper is reset is
+tracked as part of its status; if the number of resets exceeds the
+`RetryLimit`, then the AppWrapper moves into a `Failed` state and its
+resources are deleted (thus finally releasing its quota). Deletion of
+a top-level wrapped resource will cause the AppWrapper directly enter
+the `Failed` state independent of the `RetryLimit`.
 
 To support debugging `Failed` workloads, an annotation can be added to an
 AppWrapper that adds a `DeletionOnFailureGracePeriod` between the time the
