/**
 * A role can hold create_* without edit_*, and a successful create used
 * to redirect unconditionally to the new record's edit page — whose
 * can:edit_* middleware answers such a role with a 403 after the record
 * was created, logged and (for clients) welcomed. The store() methods
 * now fall back to the create form, which shares store()'s own gate and
 * is therefore reachable by exactly whoever just created the record.
 *
 * One test per entity rather than a clever loop, because each store()
 * wants its own payload — but the rule under test is the same four
 * times, and a fifth create flow should copy it.
