What this page is. An organ of the city executive: the Alcaldía, a Secretaría, a city programme or the city's own portals. Membership is computed: every published entry citing a URL the registry attributes to Seoul Metropolitan Government appears below. The classification says who publishes — never how strong the evidence is. That judgement stays on each entry, in the grade beside it.

✔ Every published entry is checked against the public sources it cites before publication.
