Record the Cut 6d leaf half

Resolutions and stewardships carry a writer-set sequence that ends their
key, so a subject's history and a repo's history each sit under one
prefix. The leaf makes the key and compares nothing; admission owns the
next-number rule. Two schemas regenerated, no epoch moved, every earlier
suite still killed.
