nx_wiki_publish_guard_sanity.nx -- READ-ONLY sanity run of the pre-publish guard against the REAL emitted live page web_assets/nist_stem.html (-> nishifamily.com/wiki/nist_stem.html). It reads the page bytes off disk (ss_readall) and runs pg_decide with the corpus = the slugs that page actually links to. Expected verdict: PG_ALLOW (the page is fresh-stamped, has zero [[cite:...]] tokens, all its /wiki/<x>.html links are in the corpus, and the body is real content). It writes NOTHING; it only inspects + prints the verdict. license_tier: ORIGINAL
