Can't reference augmented fields in a computed value

[edalzell]

Bug description

If you create a computed field but reference an augmented value, you get recursion/timeouts when you try to retrieve the entry in tinker (and elsewhere you get nginx 503, seg faults)

How to reproduce

On a brand new site, put the following in the AppServiceProvider:

 Collection::computed(
 'pages',
 'custom',
 fn (Entry $entry) => $entry->permalink
 );

Then open tinker and try \Statamic\Facades\Entry::find("home"). You'll see tinker immediately quit. If you remove the call to ->permalink and return a string instead, everything is fine

Might be related to this. I just ran into a recursion error when opening new entry route in the control panel on a collection that has a computed field referencing another field:

\Statamic\Facades\Collection::computed('podcast_episodes', 'podcast_url', function ($entry, $value) {
 return $entry->podcast?->url();
});

I did the above as per the documentation:
https://statamic.dev/collections#using-fields-from-related-entries

podcast is a related entry.

When I tried to access Entry creation route in the control panel, the server was crashing. After changing the above snippet to:

\Statamic\Facades\Collection::computed('podcast_episodes', 'podcast_url', function ($entry, $value) {
 if ($entry->id() === null) {
 return null;
 }

 return $entry->podcast?->url();
});

it works fine.

From what I understand, the infinite loop is being triggered from this method:

cms/src/Fields/Fields.php
