+- **Taxonomy and lexicon.** Raised by Captain Bob 2026-08-04, mid-item-3.1. This document's
+  physics-flavored vocabulary (heat, mass, density, patron, Stadium, and the rest) needs a
+  glossary that is explicit these are named analogies, not physical claims — and that also
+  covers the growing set of Kconfig build knobs (`STADIUM_MAX_VM_COUNT` and its siblings) so
+  the terminology in code, Kconfig help text, and this document stays one language instead
+  of drifting apart. Not scoped, not placed in a phase. Captain Bob: "I guess that we didn't
+  finish out FABRIC.md quite as much as we thought."
