which suggests a lookup table

No, it only suggests an additional field in the Post table

since there’s no assurance that any instance is aware of any other instance

It already works like that, but slightly worse because post IDs aren't the same across instances. If you search a newly-created community from another instance here, you just won't find it until it's synced, despite its URI being unique.

Thinking about it, it would be possible to have an URI for posts like post:${id}@instance.com, similar to how user URIs and community URIs are made. This way, you could open /post/1772651 on lemmy.world or post:1772651@lemmy.world on, idk, lemmy.blahaj.zone or something.
