Knowledge stub (Hermes edition)

Wiki pages grow from the first mention: start as a stub, enrich with cited facts, never overwrite. Every fact traces to a source; the ## Sources section is the audit trail.

1. sb_brief once per session — read the knowledge domains list.
2. sb_search(concept, folder="06-knowledge"). If a page exists (same thing under another name counts):
   • sb_append_section(path, "What we know", ["- <fact> — [[<source note>]] (as of YYYY-MM)"])
   • sb_append_section(path, "Sources", ["- [[<source note>]] — <date> (added: <what>)"])
   • sb_curate(path, action="enriched") → done, go to 5.
3. Otherwise create the stub. Domain: pick from the brief's knowledge domains; if none fits use unsorted. sb_create_note(type="wiki", slug="<canonical-name>", fields={domain, aliases:[<other names, acronym>], confidence:"speculation", "needs-review": true, "created-from": "[[<trigger note>]]", tags:[<topic tags>]}, preamble=<English: "Wiki page on X. <one plain sentence saying what it is>. Built incrementally from the sources below.">, sections={"Summary": "*Stub — first mentioned in [[<trigger note>]] on <date>. Awaiting more sources.*" OR a 1-3 sentence definition if the trigger gave one, "Sources": "- [[<trigger note>]] — <date> (stub created, \"<verbatim 1-line snippet>\")"}). If the trigger text states a fact, add it under "What we know" with the citation. Do not invent facts.
4. sb_curate(path, action="stub created") — lists the page in its hub or in _INDEX.md Unsorted.
5. If you were called from another skill, stop here (that skill commits). Otherwise sb_commit("wiki: <slug>").
6. Report: page path, domain, hub it landed in, and whether it is a stub awaiting enrichment.
