A table read without an order comes back in whatever order its last
updates left on disk, so the column fill could pick a different row of a
two-row table from run to run. The audit rows of a restore are now found
by the copy's id instead of by time, since the database clock and the
test's clock do not agree to the millisecond. The golden copies are
written again from the code before the restore and export moved.
Seed one account as far as the schema allows (a row of every two-ended
model, every column of those rows and of the account row, the instance
settings, a sharing grant), export it both ways and restore each file
into a fresh account, over the live account, and from a version-1 file
in the old shapes. The files, counts, parsed payload, preview, restore
outcome, reported phases, audit rows, wide-event fields and every row the
account holds afterwards are compared with golden copies after ids,
ciphertext and run-time timestamps are normalised. Refusals, skip reports
and the schema's issue list for malformed files are pinned the same way.
The seed moves out of the round-trip test into a shared fixture module
so both files fill the same account.
