## 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
     dc171test.internal. 300 SOA ns1.dc171test.internal. admin.dc171test.internal. 2026102901 3600 900 604800 300

   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 dig's documented
   `[name] [type]` positional contract (man dig) and was live-verified
   against BIND 9.18.50; no portability claim is made for other dig
   versions beyond the documented contract itself.
 3. Suites at acd0352: DNS parity 23/23; full backend 174/3754; frontend 68/68.

### Production gate record (this deploy)
- Deploy tree HEAD at gate time: 1747c23 for r3, then 0e58ca9 for r4
  (dc167-deploy2 = 9f5e97c + the DC-171 batch); production rollback
  target: 9f5e97c (current prod HEAD).
- r3 remediation commit: 9d5d640 (qualifies the dig version comment;
  adds this gate record).
- Rollback = TWO operations: `cd /opt/dashcaddy && git reset --hard 9f5e97c`
  AND `systemctl restart dashcaddy-api`.
- Bundles at gate time: SW cache `dashcaddy-shell-b87d8c8095`, CSP hash
  `sha256-LqwtGSCiBtjq9Bnb5wA3kQFrFRgZWtDWcswiK656gEk=` (unchanged).
- Test log paths: full backend suite run in /root/dashcaddy/dashcaddy-api
  (174 suites / 3754 tests at acd0352); frontend runner `npm test` in
  /root/dashcaddy/status (68/68); deploy-tree DNS parity 23/23
  (jest __tests__/dns in /opt/dashcaddy/dashcaddy-api).
- Judge grades for this deploy: r1 D (urn:ump:iesjvepuqb5poim7wu22ff4jtd5vhpw2lotfhogljemsw2h4y6vq),

  blocker: unqualified 9.11-9.16 comment in rfc2136.js, fixed by 9d5d640),
  r4 C (urn:ump:iysmn53oxuhn57y5v6emmztvbissz275wl3wbp2pa2w5ou77mvua —
  blockers: stale gate record naming 1747c23, the 'ALL dig versions'
  phrasing, and no r4 entry; all three addressed in this update).
