 "verdict": "Type confusion certain by inspection: both hash-walk matches call netaddr_match(AF_INET, &rp->rc_haddr, nd->nd_nam) unconditionally regardless of whether the entry stored an IPv4 address (RC_INETADDR) or a duped sockaddr (RC_NAM, the default for non-AF_INET transports), so a v6-created entry has its rc_nam heap pointer read as an IPv4 address - 32-bit equality oracle for a spoofer and a silently inert duplicate cache for v6. Dynamic proof requires running legacy kernel nfsd on an AF_INET6 datagram socket plus source-spoofed probes; the config gate (admin sets up v6 nfsd) kept it out of this batch. Fix branches on RC_INETADDR; compile-validated.",
