It's fixed now. My issue was more severe than most people's because somehow the installation got interrupted? I don't know.
I do not yet know whether the system update itself was to blame after all. But Z fixed my boot cache or something, and manually re-copied over the damaged files, and did some other magicky stuff, and it works now.
So hurrah. I've told him to name his reward but haven't heard back yet.
