Side A is a small, precise UX/architecture fix: it replaces redirect-based auth flow with fragment responses and a JS morph, is correct, coherent, and consistent with the existing poem-JS pattern, with matching CSS additions. Side B is a large CLI restructuring (renaming ingest->forum post, forum->forum list/show) that is mostly churn/renaming across docs, main.rs, rpc.rs and tests, and even introduces a minor regression by removing the escape_xml helper in favor of unescaped body output.
