Two sentences added to an existing section; nothing else touched.

## 6. One fact, one place, linked from everywhere else.
+ **This applies inside a single page too.** Design Document r6's Appendix A defines the same two
+ conductors twice — once as *power line / signal line* and once as *signal cable / power cable* — and the
+ body uses both wordings about equally, so a reader meeting both entries concludes there are four cables.
+ A glossary that grows by accretion will do this quietly; when you add a term, check the list you are
+ adding it to.

If you find yourself restating another page's rule, link it instead. If you must restate it, say where
it is canonical and that yours is a copy. Divergent copies are the characteristic failure of a wiki used
as a pile of documents, and they are expensive precisely because both copies look authoritative.
