Review finding 7, second part: a record carried into a new epoch whole
(proposal and decision in one change) was taken from any member, for
any remake ID. A member could write a forged record, decision included,
for a fresh ID in a single change.
The snapshot's epoch metadata now names the remake's coordinator, as
the quorum built it. The carried-record exception holds only in a
later epoch, only for the remake that made it, and only from the
coordinator its snapshot names, where there is no record yet. Wire
version 43: the snapshot, and so the epoch ID, changes.
The review suggested carrying the record inside the snapshot instead.
The snapshot can't hold the decision, which names the snapshot's own
hash. So the snapshot vouches for who may carry the record instead.

A switching or rejoining node replays late writes as fresh changes
naming each write's user, and nothing judged them before they left: a
replay every node would refuse (a revoked capability, a second
envelope at a signed path, readers changed) was refused everywhere,
and with it everything the node wrote after it.
Under a policy, replay_newest now judges each group it commits as
every node will (rules::judge_held, in the new epoch); one they would
refuse is taken back (forked at the heads before it, same actor) and
its paths quarantined with the reason. replay_newest takes the epoch.
Review finding 3 (remake replays).

A remake's replay writes each value as the user who wrote it,
splitting where several users wrote under a path, so replays are
judged as the original writes.
Auth plan M6 (remakes, 2.4).

This allows a lot of operations to drop mut.

The Clock module is the system clock that every unix timestamp new goes
through. It comes with an offset that only tests can set.
