##
## Finally, the staged data are merged into the physical backend
## database and the staged data area is cleared.
##
## The argument `nxtSid` will be the ID for the next saved state record.
##
## Staging the top layer cache might fail with a partial MPT when it is

{.noRaise.}
## Re-focus the `db` argument descriptor so that it becomes the centre.
## Nothing is done if the `db` descriptor is the centre, already.
##
## With several descriptors accessing the same backend database there is
## a single one that has write permission for the backend (regardless
## whether there is a backend, at all.) The descriptor entity with write
## permission is called *the centre*.
##
## After invoking `reCentre()`, the argument database `db` can only be
## destructed by `finish()` which also destructs all other descriptors
## accessing the same backend database. Descriptors where `isCentre()`
## returns `false` must be single destructed with `forget()`.
AristoApiRollbackFn* =
proc(tx: AristoTxRef;

AristoApiTxBeginFn* =

AristoApiTxTopFn* =
