The 1.0.60 ref-list summary is taken after attach, an upsert of alpha, beta and the list reversed, and a flush, at 2.0.1 and at
head, and names records by schema id (the restamp-on-write ruling makes them equal). C2aGateWriter stamps every record with one
instant and compares the committed vectors byte for byte, the directory store as relative path and bytes with lock files left out.
The committed vectors are regenerated in the next commit, so TheCommittedVectorsAreWhatC2aWrites is red at this commit; it builds.
