One page owns the relayout facts: the new section carries the Plex-only reader, the shape, the four commands, and the two laws a future operator would otherwise re-litigate (never renumber a chapter; the shelf is the narrator). The music section said its plan was NOT applied — it was applied on 2026-10-31, and a stale line in a runbook gets believed, so it now names the journal and the rollback.
