Interesting point, I was thinking more about the latter, but you are right that issues and PRs are the more important piece.

It does look like Tangled currently does those in a weird way, ties to the issue owner rather than repo - but here’s a proposal to fix: https://leaflet.pub/p/did%3Aplc%3Axasnlahkri4ewmbuzly2rlc5/3...

Doing some weird distributed join across all your committer’s PDSs seems a bit weird, and the semantics of cross-referencing issues seems gnarly in that world.

I think I’d be OK to model a PR as a tweet, it’s more owned by the sender. But issues seem like they should be owned by the repo for sure.
