The store now carries an inbuxa store version (1), kept in the fork's subspace beside the 0.16 schema version, which stays as it is. A store without the mark, from an older release or from Stalwart, gets it on start. A store marked newer than the running release is refused before anything writes to it, with a message pointing at the newer release or the pre-upgrade backup. Layout 1 is what 2026.x and 27.1 both write today, so the same check goes to release/2026: a 2026.x release then refuses a store a later 27.x has changed instead of opening it.
