lane

The opaque fair-share Lane this task rides. Defaults to Lane.ROOT — no lane, the untagged path — so warp core assigns it no meaning and an untagged descriptor is byte-for-byte unchanged on the wire (CBOR omits a field at its default). An enforcement adapter (:kuilt-warp-heddle) binds the tag to a fair-share leaf and gates execution on entitlement; warp core never interprets it.
