BUNDLEFIX-056: designate public/internal bindings -- F-CV1 RESOLVED (fix executed + verified) ...

designate's REST API public+internal endpoints were omitted from the bundle,
defaulting to the '' metal-admin fallback -> orphaned the provider + metal-internal
legs of its ruled .62 VIP triple (D-020 amendment) -> _admin haproxy backend SSL-DOWN
on the unserved metal-internal address. The deployed charm declares public/admin/
internal extra-bindings (metadata verified); dnsaas (D-106) is ADDITIONAL, not a
replacement -- the prior "no public binding" reading was the defect's root.

Config-of-record: bundle.yaml +public:provider-public +internal:metal-internal;
provider-bundle-check EXPECT_PUBLIC_VIP 11->12 (vault stays out, not 13) with T16c/T16d
failing-direction tests (57->59, ALL PASS); network-space-binding-reference row 88 +
note. Gauntlet ALL GREEN (99); repo-lint 0-fail.

Live (operator-approved): juju bind designate public=provider-public
internal=metal-internal (rc=0, dc0 rack). Verified: full haproxy sweep 0 DOWN
cloud-wide; apache https vhosts span all 3 planes; cert reissued for provider-public;
catalog triple correct (public 10.12.4.62 / internal 10.12.12.62 / admin 10.12.8.62).

Governing: D-052 / D-020 amendment. Evidence:

D-052 RE-AMENDMENT: ovn-central '' default metal-internal -> metal-admin + network binding reference ...

- ROOT: the '' default is the MANAGEMENT binding (primary NIC + juju agent<->controller),
  universal '' = metal-admin across all 56 apps. The 08-03 amendment ('' -> metal-internal,
  never deployed until 08-04) left ovn-central single-legged on the isolated metal-internal
  plane -> no route to controller (10.12.8.5:17070 unreachable) -> agent-binary download failed
  -> ovn-central never started. Its cert rationale was already withdrawn; cert CN is fixed
  independently by the /etc/hosts postruncmd (dc-node-etchosts.sh, Step 1.2b).
- bundle.yaml: ovn-central '' -> metal-admin; functional endpoints (certificates, ovsdb*,
  coordinator) STAY metal-internal. provider-bundle-check 55/55, repo-lint 0 fail.
- D-052 RE-AMENDMENT 2026-08-05 recorded (GA-R5, operator utterance quoted). Scope: ovn-central
  only; every other binding re-verified correct vs dataflow (ruled exceptions: D-072 dashboard,
  D-106 designate:dnsaas).
- NEW docs/network-space-binding-reference.md: 6-plane roles + CIDRs + RHOSP analogs, the ''
  management-binding rule, full 56-app placement matrix, dataflow confirmation, ruled exceptions.
- Stage 5 remains OPEN. NEXT: re-stage bundle to rack, re-home ovn-central on the live model,
  then vault init (operator-only) -> ovn cert -> converge.
