Wiki Audit

Verify a single wiki page against its cited sources. Two phases: detect uncited factual claims, then verify cited claims by dispatching one subagent per source in parallel.

Pre-condition

Find SCHEMA.md (search from cwd upward, or ~/wikis/). If not found, tell the user to run wiki-init first. Read SCHEMA.md for the wiki root path and the Citations section (the rules and footnote format the audit enforces).

If SCHEMA.md has no Citations section (older wiki, initialized before this skill existed): use the fallback convention below for this run, and offer at the end to append the Citations section to SCHEMA.md so future operations stay consistent.

Cite every non-common-knowledge factual claim. Granularity is paragraph or claim,
never per-sentence. Format: Markdown footnotes. Two citation kinds:

Quote:     [^N]: <target> <locator> — "<verbatim quote>"
Synthesis: [^N]: <target> <locator> [synthesis] — <what supports the claim>
