A condition names a record by (stored schema id, storedAt), and that name must
say which bytes are stored. A single-file whole-view write (plain flush, or an
unconditional commit) re-encoded every record under its own type's id with the
storedAt it loaded, so the pair could name two byte strings: v1 shed a member
keeping storedAt, a second v2 cache restored v2's id keeping it again, and a v2
cache holding the original bytes committed its condition (Soul F6, A-B-A).
Now such a write stores a record under a later storedAt whenever it stores it
differently: under another id than it was loaded under, or with other bytes than
the file holds at that storedAt (a record written with the ids it minted at
load, for one). A record stored exactly as the file holds it keeps its storedAt.
The store's entries and the cache's take the id and storedAt the write gave them.
Tests: the A-B-A through commits and through plain flushes, with Expect and
ExpectUnchanged; a flush that re-encodes a record restamps the cache that
flushed (a condition holds straight after, SM12); a record stored unchanged keeps
its storedAt through commits and flushes; persisting load-minted ids gives a
later storedAt. The rolling-deploy test asserted v1's rewrite kept storedAt; it
now asserts a later one, since that rewrite is a new store of the record.
