-     *      kept the same, or reduced, then {@link ReplicasAction} is executed first, otherwise, it is last.
-     *      So the ordering looks something like this:

+//     * This action provider returns an ordering for the actions within each of the four timeseries phases.
+//     *  Hot Phase:
+//     *      The Hot Phase only supports the {@link RolloverAction} and so that is the only action to order
+//     *  Warm Phase:
+//     *      The Warm Phase executes the supported actions in a slightly complicated order for the sake of
+//     *      optimization. Assuming the {@link ReplicasAction} is specified, it will run first or last depending
+//     *      on whether it increases, decreases, or keeps the existing replica count. If number-of-replicas is
+//     *      kept the same, or reduced, then {@link ReplicasAction} is executed first, otherwise, it is last.
+//     *      So the ordering looks something like this:
+//     *          - {@link ReplicasAction} (if action.number_of_replicas lte idxMeta.number_of_replicas)
+//     *          - {@link AllocateAction}
+//     *          - {@link ShrinkAction}
+//     *          - {@link ForceMergeAction}
+//     *          - {@link ReplicasAction} (if action.number_of_replicas gt idxMeta.number_of_replicas)
+//     *
+//     *      NORELEASE: there may exist further optimizations to this when {@link ShrinkAction} is specified.
+//     *
+//     * @param context the index lifecycle context for this phase at the time of execution
+//     * @param phase the current phase for which to provide an action provider
+//     * @return the {@link LifecyclePolicy.NextActionProvider} for {@code phase}.
