Struct ImportSpoolReservation 

pub struct ImportSpoolReservation<'a> {
    pub spool_uuid: &'a [u8],
    pub logical_job_id: &'a [u8],
    pub branches: &'a [ImportBranchLimitV1],
}

Independently retained refs/slots for one non-terminal logical job. Include Prepared jobs and all original refs until logical termination, not just the current certificate’s remaining scope. Hosts provide the complete inventory under the same transaction that reserves/activates; this helper stores nothing.
