Accidentally changed default certificate trust on Mac?

I may have accidentally changed the default Certificate Trust setting on my iMac. I have no idea where the default setting is. I have looked in the Keychain app, and all I see is a list of unintelligible sites, but nothing about a default that I can see.

I want to be able to see the default and to be sure I didn't set some sort of "trust all" or similar type of setting. (What should the default show?). If I did change it, how do I change it back?

I am using Sequoia 15.3.1 on an iMac Pro.

Thanks for any help. Please answer like I'm a newbie/4 year old, because I'm not very adept.

iMac Pro, macOS 15.3

If you are unsure of what you did or what happened or how or concerned you have corrupted your environment, erase and restore your Time Machine backup from immediately prior to whatever happened.

That means you’ll need to describe what happened.

It might be entirely benign. Or inconsequential. Or nothing happened. Or who knows what?

That’s also assuming whatever happened is reversible too, as some operations in Keychain Access are not.

Restoring a backup gets you back to the previous state.
