Publication standard
English articles are published only after source review, official API checks where applicable, JavaScript syntax review where code is present, duplicate-intent and link checks, and editorial review. Publication does not imply Console or multi-tick live-room verification; those evidence states remain separate in each guide. Review the verification method.
