Thanks!

This now renders properly; see T13429 for followup.

I did some trial and error last week with Twitter via https://cards-dev.twitter.com/validator. That was for my personal blog, but some of it might apply here as well.

See PHI1492. After this change, the parent/subproject modes of the script in T10350 can be brought upstream safely, since they would no longer be destructive operations on membership lists. This wouldn't cover the "convert a project into a milestone" mode, but that seems less important.

Thanks!

Context isn't automatically unfolding around inlines, but should.

Oh, and maybe lack of source code intraline diffs, although that's likely not too much work.

I think the major remaining issues are:

One broad problem here is "chain of custody" issues in T182. A "Saved State" can easily accommodate multiple representations, and the plan above imagines using Drydock to build tags/branches out of non-repository representations, so we'd have cases where a given "Saved State" has a way to build it with a "patch list" (from the client) or a "ref pointer" (from Drydock).

ODIC is just OAuth2 in a ghost costume, so the implementation is nearly trivial.
