+## Promote a section to its own page
+
+A subject can live as a section of another page until it earns its own - the shipped `entities`
+profile does this with people on their organization's page. Promoting one is not a move: a new
+page is born, and a section shrinks. No command does it in one step, because two of its steps
+are judgments - which edges meant the person and which the organization - and it is rare.
+
+1. **Create the page** from the section's content, with the tool:
+
+   ```bash
+   tools/wikitool new entity --name "<Name>" --set entity_type=person --set provenance=<value>
+   ```
+
+   Move the section's prose into it, and its citations with `cite add` against the same sources.
+
+2. **Shrink the section** on the parent page to one bullet under the heading that held it -
+   `- [[<Name>]] - <role>` - and drop the section's own heading. With the heading gone, any link
+   step 4 misses stops resolving and step 5 reports it, instead of landing quietly on a stub.
+
+3. **Connect the two** - for a person, the membership edge on the new page:
+
+   ```bash
+   tools/wikitool xref add --a "<Name>" --b "<Organization>" --rel member-of
+   ```
+
+4. **Find every link that meant the section**, and point it at the new page:
+
+   ```bash
+   tools/wikitool search "[[<Organization>#<Name>"
+   ```
+
+   Search is literal by default, so the brackets need no escaping. Rewrite each hit to
+   `[[<Name>]]`, and move any edge on those pages that meant the person - `consults:
+   <Organization>` for a client contact, say - from the organization to the new page with
+   `xref remove` and `xref add`. An edge that meant the organization as a whole stays.
+
+5. **Check** - `tools/wikitool lint` reports no `broken_anchors` and no `broken_links`. Then close
+   out as for a new page.
