| 1. Finds a feasible node using the standard per-Pod filtering and scoring phases. | ||
|
|
||
| * If the Pod fits, it is temporarily assumed and reserved on the selected node until the end of the scheduling algorithm. | ||
| * If the Pod cannot fit, the scheduler attempts preemption by running the default `PostFilter` extension point. |

What do we mean by "default PostFilter extension point" here?

Good question, removed the "default"
| rather than a single-cycle approach. | ||
| It utilizes the [PodGroup scheduling](/docs/concepts/scheduling-eviction/podgroup-scheduling/) cycle to make a single, | ||
| atomic scheduling decision. The `Permit` extension point, implemented by the `GangScheduling` plugin, | ||
| is used to determine whether the `minCount` constraint is satisfied during that cycle. |

When putting on a hat of somebody without the WAS expertise and reading this bullet point as it is right now, it's unclear to me what constraint exactly is being verified in the Permit extension point.
