Code-certain dead-body check; NOT a reachable OOB today (checkdata gate confirmed at the case 0x07/0x57 tail: dlci > 1023 -> goto reject). This corrects the framing of sibling DF-0564 (same file/lines, claimed reachable OOB - it is not, same gate). fix.diff implements the intended bounds check locally so rcvdata no longer relies on a distant validator; the identical empty body also exists in the netgraph v1 copy sys/netgraph/lmi/ng_lmi.c:698-704 (noted for the orchestrator to file separately if desired).",
