Review finding (PR #791): with no projection definitions registered, restoreFloor() is undefined and the fast path returned a successful empty snapshot without touching persistence — a nonexistent session 'succeeded', violating the documented not-found contract in that supported topology. The no-unit branch now probes readFrom(id, 0): an absent log rejects with the seam's not-found, a present one dates the empty cut at its stored end.
