about

nx_mdns_test.nx -- offline gate for the mDNS / DNS-SD printer-discovery parser (nx_mdns). Hand-builds a realistic mDNS `_ipp._tcp` response -- PTR + SRV + TXT + A, with NAME-COMPRESSION POINTERS on the SRV/TXT/A owner names (exactly what real printers emit) -- then proves nx_mdns extracts the printer tuple. Unique exit codes per invariant: 1-10 extract port=631 (SRV) + IPv4 192.168.8.127 (A) + TXT rp=ipp/print, through compression pointers 20-24 query builder emits a well-formed _ipp._tcp.local PTR question 30-31 truncated response -> sealed MALFORMED (NEVER a silent success) 40 absent record type -> NOT_FOUND (no false hit) expect_exit: 0 ; license_tier: ORIGINAL ; genealogy_id: project-printer-management-ipp-sclass-2026-06-20
