The crack before I repaired it

that topic has a bit on slipping 3t seatposts

I presume you've added carbon paste to the mix?

Can you stick a stick (or something suitable) underneath the post so the seatpost hits it at the right height and stops.

Yes pasted up

The stick could work. Otherwise I'm covering the seatpost in epoxy and setting it to the right height and being done with it

I think that would be my first option.

The frame was essentially free, I just paid for the parts so I think I might as well. Currently its not able to be ridden so it can't end up worse

That was my thinking too. It's on at least it's second chance at life, so why not.

Can you get a Coke can shim down the front to take up the slack? Might do the trick.

That was option #2. But life is too short...

I’m guessing it’s not di2? Otherwise a glued seatpost is going to get difficult to rewire...

Also which way does the disc brake hose go? Top tube or down tube?

No, Sram force, everything goes (badly) routed down the downtube

FFS, you could drive a bus down the gap between the frame and the post.
