The v9→v10 migration converts every valid draft edge one-for-one into a
partition. A valid existing segment id is retained; a missing id is generated
deterministically from the space, draft and edge index. Draft order and each
edge's `cm` are preserved, existing partitions are not merged, and the carrier
record is removed atomically. Malformed geometry, invalid thickness or an id
collision fails closed. A current v10 document containing `room_drafts` is
