/**
 * A recorded day taken into a journey with its stays (JRN-02), through the
 * real AddonGuard, JwtAuthGuard and Zod pipe against a migrated and seeded
 * temp SQLite db, every answer checked against its response contract. The
 * Dawarich client is the one thing replaced: a test never opens a socket to a
 * location archive. The broadcasts go to a FakeRealtimeService.
 *
 * Fixtures: user 1 owns journey 7 and has a Dawarich connection, user 2 is an
 * editor of it with a connection of their own, user 3 a viewer.
 *
 * The walk: review the day, take two stays over as one entry and leave the
 * parking out, send the same take-over again without a second copy, and be
 * refused for a stay that is not the caller's or a group the contract refuses.
 * The drafts written stay off the journey's public share.
