instant: clean
One cached scope on the probe-shell profile, rendered directly with no boundary. Its 10 minute stale time makes it App-Shell eligible, so validation passes and the navigation into this tab is instant.
What to check
In dev, no insight appears for this tab. In a build, clicking here from another tab shows no pending dot in the nav.
Change probe-shell to probe-no-shell in this file and reload in dev. The insight appears and names this component. That one-word edit is the difference between the clean and blocking tabs.

Prerendered and in the App Shell, so it ships with the prefetch rather than being fetched on click.
