Hyper.Img.Db.Blob (Hyper v0.1.0)

An immutable, content-addressed leaf object stored on NFS - a base (P.img) or a delta (L.img). The id is both primary key and identity, so inserts are conflict-free: two nodes publishing the same bytes write the same row.

The only field that ever changes is state, flipped to :deleting as a tombstone during a coordinated delete so no new lease can be taken against it.
