    Variable ID_PARTITION_LANESConst

    ID_PARTITION_LANES: 256

    The lane count every residue class is computed against.

    A constant rather than the pool size: a lane cannot read the primary's lanes_provisioned (cfw_meta is replica-local), and a count read from env left the partition off on every deployed pool. Set at replicaCount's ceiling so every lane holds a distinct non-zero residue.
