Releasing a drawing set makes one nest per material group, so a kit run spans several nests. The server now records which set revision was released, the multiplier and the nests it made, so a run can be tracked across its nests and a nest can say where it came from. The client uploads every nest first and posts the release last: a failure part-way leaves ordinary nests and no release, never a release pointing at missing nests. For the same reason a release is accepted for an older set revision or an archived set, since the nests already exist by then. The release id is client-allocated and a nest belongs to at most one release, so a retried post gets 409 with the release that already holds it. Releases are append-only and read joined to each nest's current metadata, so status and deletion are always current. The tables join schema v7, as the set tables have not shipped yet.
