/**
 * What happens to stored AI text and stored Coach rows, against the real
 * server, on an account of its own (`E2E_AI_OPTIONAL`).
 *
 * J5 — consent withdrawn. The account has a local model (an address nothing
 *      listens on: presence is all the capability reads, nothing here calls
 *      it), a daily briefing a model wrote earlier, and an AI consent. The
 *      briefing is on the overview; the consent is withdrawn in Settings, AI
 *      through the real control; the briefing is gone, because the server
 *      deleted the notes written under that consent.
 * J4 — Coach hidden. With Hide Coach on, Settings, Coach is out of reach, so
 *      Settings, AI lists what the Coach stored; one stored conversation is
 *      deleted from there and is gone from the database.
 *
 * Both journeys move the same account's state, so they run serially, in one
 * project (see `playwright.config.ts`).
