Type errors for freeze(causalConsole);

[kriskowal]

I’m locally seeing LSP hints that freeze(causalConsole) in two places within ses/src/error/console.js due to a combination of freeze (unlike harden) translates all the properties into readonly versions, and the runtime uncertainty about this code generating all the properties of VirtualConsole. We could either cast here, or cast freeze to a pass-through identity function type, or some combination.

I did not understand this. "LSP"?

Language Server Protocol. It’s the thing that lights up lint errors in VS Code, and I have a Vim plugin that uses it. TSC isn’t complaining about it in CI because the file doesn’t have // @ts-check, but that doesn’t prevent IDE’s from noticing.
