```ts
type WorkspaceRetention = | {
    readonly count: number;
    readonly kind: "panes";
    readonly reason: "pruning-disabled" | "shared-window";
    readonly window: WorkspaceWindowPlacement;
  }
| {
    readonly kind: "window";
    readonly reason: "grouped-session" | "pruning-disabled";
    readonly window: WorkspaceWindowPlacement;
  }
```
