+**generated regions** render under - the links region `wikitool xref` owns and the footnotes
+region `wikitool cite` owns. Each sits between a marker pair, and the marker is what the tool
+locates it by, so the heading here is a display value: changing it re-renders the words above
+those regions and nothing else. Nothing matches on this text.

 ### Section headings
 
-The canonical names are the frontmatter's: `## Beziehungen`, `## Siehe auch`, `## Fußnoten`.
-The English forms this stack wrote before the corpus was translated are still recognized, so a
-page carrying `## Relationships` is found and appended to correctly and `cite sync` leaves an
-untranslated `## Footnotes` alone. Renaming such a heading is the translation pass's job, never
-a side effect of another command. Any *other* heading an author adds is ordinary prose and is
-translated with the rest.
+The two generated regions render under `## Beziehungen` and `## Fußnoten`. An author never
+writes inside them - they are rebuilt from frontmatter on every write, exactly like
+`kb/index.md` - and never has to write the heading either. Any *other* heading on a page is

 ## Relationship labels
 
-`tools/wikitool xref add --rel-a/--rel-b` takes a free-text label. This instance uses a typed
-one rather than a generic one:
-
-`hängt ab von` · `verwendet` · `implementiert` · `erweitert` · `ersetzt` · `steht in Konflikt mit`

-The labels are prose written into a `- **label:** [[Title]]` bullet; no code matches on them, so
-an untranslated page's English label is stale wording, not a broken reference.
+**Not this file's to list, and not localized.** A label is a machine value in `related:`, drawn
+from [instructions/link-taxonomy.md](../instructions/link-taxonomy.md) and authorised per
+destination in each `kb/<name>/COLLECTION.md`'s `outbound:` block. `- **depends-on:** [[Hermes]]`

+it would make the graph's semantics depend on the prose again.

 ## Keeping this file honest
 
-Change it when a convention actually changes, and treat a change to `sections:` as a corpus
-migration rather than an edit: existing pages keep their old headings until something translates
