## DC-171 phase 1 — BIND 9 live AXFR verification (2026-10-30)

Deploy judge r1 (dc-prod-deploy-dc171, grade D urn:ump:iesjvepuqb5poim7wu22ff4jtd5vhpw2lotfhogljemsw2h4y6vq)
blocked the cutover on dig argv order (AXFR/zone swapped vs the documented
`dig [name] [type]` contract) and demanded verification against an actual
BIND 9 endpoint. Resolution (fix commit acd0352):

1. ARGV FIXED to `@server -p port <zone> AXFR +options` (documented order).
2. LIVE BIND 9 ENDPOINT: a real BIND 9.18.50 (Extended Support Version —
   the line Ubuntu 22.04/24.04 ship) was stood up in Docker
   (internetsystemsconsortium/bind9:9.18) on this host with zone
   `dc171test.internal` (master, allow-transfer any; SOA/NS/3xA/TXT/CNAME
   records). The ADAPTER'S OWN CODE PATH (real execFile dig, real parser,
   zero mocks) ran listRecords({zone:'dc171test.internal'}):

   BIND 9 LIVE AXFR VIA ADAPTER — SUCCESS
   zone: dc171test.internal | count: 7

   types: SOA,NS,A,TXT,CNAME

   named.log: `zone dc171test.internal/IN: loaded serial 2026102901`.
   The same check against the production Technitium server (100.121.150.22,
   zone `sami`) returned 48 records (SOA/A/NS, real fleet names) — the
   AXFR path works across both server implementations; BIND is the
   judge-required one and is satisfied above. Older-dig (9.11–9.16)
   leniency could not be reproduced in-container (bullseye security
   mirrors currently 404); the shipped argv follows the documented
   positional contract on ALL dig versions, which is the portable form.
