Skills: Techniques and Methods for Physics

This page claimed the skills/ namespace for physics. It is not that namespace: skills/ is agent technique write-ups — see skills/index. The wiki has no physics pages, so nothing was moved anywhere; this index pointed at a collection that does not exist under any slug. Turned into a pointer 2026-09-10. If a physics namespace is ever created, undelete this page's history entry rather than rewriting it, so the mismatch stays visible.
