about

nx_netscope_dissect.nx -- NX-NETSCOPE L4: layered PURE typed dissectors (Wireshark/Zeek-EXCEED) + the canonical hashable dissection digest. Charter principles honored: pure bytes->typed-tree functions (no state, no syscalls in the dissectors themselves), DETERMINISTIC (same bytes + same ruleset -> byte-identical digest -- the headline determinism EXCEED no incumbent gates), LOUD-fail on unresolved cases (a clear UNRESOLVED verdict in the tree, never a silent mis-parse). REUSES nx_dns_get_u16_be (big-endian u16) from nx_dns.nx and nx_sha256_one_shot from nx_sha256_wasm.nx (now compilable on the native lane after the `~` parser fix) for the canonical digest. Stack: Ethernet II -> IPv4 -> {TCP, UDP, ICMP}. IPv6/ARP tagged but not deep-parsed yet (LOUD UNRESOLVED, not silent). license_tier: ORIGINAL genealogy_id: nishi_nx_netscope_l4_dissect
