v0 state

Record

Record is v0's shape. v1 changes it, which is the whole reason for a new version: a stored-layout change is never done in place.

Get

Get returns a record or nil. Non-crossing: v1 reads through it while migrating, and gnoweb can call it without a transaction.

Size

Size is how many records still live here. It never shrinks: lazy migration COPIES forward, it does not move, so v0 keeps paying for every record it ever held.
