* Cosmetics, spelling, etc. * Aristo: make sure that a save cycle always commits even when empty why: If `Kvt` is tied to the `Aristo` DB save cycle, then this save cycle must also be committed if there is no data to save for `Aristo`. Otherwise this will lead to excessive core memory use with some fringe condition where Eth headers (or blocks) are downloaded while syncing and not really stored on disk. * CoreDb: Correct persistent save mode why: Saving `Kvt` first is seen as a harbinger (or canary) for `Aristo` as both run in sync. If `Kvt` succeeds saving first, so must be `Aristo` next. Other than this is a defect.
