+### kb/CONTRACT.md names section anchors in wikilinks and the Broken Anchors finding
+
+The stage contract's rules for writing a wikilink (§ Titles are identifiers) covered wrapped links
+but not `[[Title#Section]]`, which the previous bump made a checked form. It now says that the
+title part is the reference (the graph counts it, `rename` carries the anchor), that a stale
+anchor is reported as advisory *Broken Anchors*, and that a section is never an edge target.
+Found in the closing pass of Gitea #172.

 Wikilinks* hard error, naming the title it folds to - the graph, `rename` and `rm` already read

+**A wikilink may name a section of its page: `[[Title#Section]]`.** The title part is the
+reference - the graph counts it as a link to `Title`, and `rename` carries the anchor along - so
+an anchor never makes a link broken. It can make one stale: a section renamed, or promoted to a
+page of its own ([instructions/page-lifecycle.md](../instructions/page-lifecycle.md)), leaves the
+link reaching the right page and the wrong place. `wikitool lint` reports an anchor that names no
+heading on its page as *Broken Anchors*, advisory - compared at any heading level, without case,
+inline-code backticks or extra whitespace. A section is never a target in `related:`; an edge
+points at a page.
