Struct SuccessorCeremonyId 

pub struct SuccessorCeremonyId(/* private fields */);

The id of the successor a plan opens, derived from the plan itself.

Derived rather than supplied, for the same reason a child’s id is: the sealing of the plan and the opening of the stream are two appends, and a crash between them has to be resumable. A caller that chose the id could retry with a different one and open a second successor for one plan; a derived id makes the retry land on the stream the first attempt was opening.

The predecessor is spelled out rather than hashed in, so the relation is legible in a store listing without reading a stream.
