unkinben da4a66046a Add Tier-2 per-app Vector transform pipelines (structured logs) (#320)
Why: extend the Tier-1 survey with 7 more high-value log sources so they parse into logs.raw columns/.fields for real querying instead of the generic catch-all. **Stacks on #318 — merge after it.**

How:
- 7 mutually-exclusive app_route conditions + parse transforms into the ClickHouse sink: **bind_query** (k8s bind-* + VM named), **rancher_audit** (cattle-system sidecar JSON), **cnpg_pg** (ONE transform for all 10 CNPG clusters via the `.postgres` container), **gitea** (router+access, k8s+VM), **puppet** (openvoxserver/openvoxdb logback + access), **litellm** (JSON request logs), **postfix** (per-line maillog).
- Carve `.postgres` out of the Tier-1 authentik route + new puppet/gitea/litellm routes so the single cnpg_pg route claims every CNPG pod without double-insert (keeps app_route mutually exclusive). Catch-all intact.
- Companion k8s flips in this PR: litellm `JSON_LOGS=True`; bind `querylog yes` on both bind-internal BindClusters; gitea router+access logging to stdout. Rancher auditLog was already on.
- 15 new `vector test` cases (routing + field extraction + authentik-postgres→cnpg exclusivity proof); all 35 green (vector 0.57). Fields go into the existing `fields Map(String,String)` — no DDL change.

Puppet-side follow-ups (out of scope for argocd): enable named query logging (profiles/dns/server.pp); ship the VM vector rollout with `.file`/`.SYSLOG_IDENTIFIER` tags for named/gitea/puppetserver(+multiline logback join)/postfix maillog.

unkinben f1c3b9617f Add agent-dns RBAC: static SA + ClusterRole + per-namespace RoleBindings (#332)
## Why
Vault's kubernetes secret engine will mint scoped tokens for a static \`agent-dns\` service account instead of generating cluster-wide RBAC, so agent DNS access is confined to exactly the bind namespaces. This is the GitOps half of the terraform-vault agent-dns role rework (PR unkin/terraform-vault#109). Ordering: this must sync before the Vault \`agent-dns\` creds are usable — Vault mints tokens for an SA that must already exist.

## How
- Add ServiceAccount \`agent-dns\` + ClusterRole \`agent-dns\` (definition only, no ClusterRoleBinding) in \`bind-system\`: full verbs on \`bind.unkin.net\` CRDs, get/list/watch pods/services/configmaps/events, get pods/log.
- Add RoleBinding \`agent-dns\` in each of \`bind-system\`, \`bind-internal\`, \`bind-external\`, \`externaldns\`, binding the SA to the ClusterRole in that namespace — confining all access (reads included) to those four namespaces.

Whitelist note: the platform AppProject already permits ClusterRole/ClusterRoleBinding and all four namespace destinations, so no project change is needed.

unkinben d04940b1ea Pull in-estate service images from artifactapi docker-internal (#310)
Move the estate's own service/operator image pulls off the Gitea container registry (git.unkin.net/unkin) to the artifactapi local docker registry (docker-internal), ahead of the git.unkin.net forge migration which disables Gitea's container registry. The images were copied digest-for-digest into docker-internal and pulls verified before this repoint.

- repoint age-api, bind-operator, bind-tsig-api, cephrgw-operator, encapi, logarchiver, pdbmux image pulls to artifactapi.k8s.syd1.au.unkin.net/docker-internal

Deliberately not repointed here: artifactapi's own api/ui images (circular — it can't pull itself from itself), and the almalinux9-* base/CI images (huge, and their per-repo Woodpecker push targets move in a batched follow-up). Forge raw-CRD URLs and git clone sources are unaffected (those stay on the forge).

unkinben a04dcc2975 Add k8s Gitea deployment (migration target for git.unkin.net) (#309)
Stand up the git.unkin.net forge on k8s to replace the Puppet VM. Deployed HA-shaped to match what the VM already runs (multi-replica on shared storage + external DB/cache), so this is genuine multi-replica HA rather than single-replica failover. Serves a temporary git2.k8s.syd1.au.unkin.net host; the git.unkin.net cutover is staged in docs/gitea-migration.md.

- add apps/base/gitea: namespace, CNPG gitea-postgres (2 instances, S3 backup bucket cnpg-gitea, nightly 04:00/30d), pgbouncer pooler, standalone Valkey (session/cache/queue, AOF), VaultAuth + VaultStaticSecrets, Gateway + HTTPRoute
- add apps/overlays/au-syd1/gitea: official Gitea chart 12.6.0 (app 1.26.2, rootless, 2 replicas) via helm-through-kustomize; RWX CephFS repo storage, external CNPG + Valkey, Actions disabled, container registry disabled (moved to artifactapi), Authentik OIDC with auto-register/account-linking; SSH via LoadBalancer VIP 198.18.200.10:2222
- register gitea in the platform ApplicationSet + AppProject
- add docs/gitea-migration.md staged cutover plan (VM Postgres->CNPG dump/restore, DNS in main.unkin.net zone, consumer checklist, rollback)

Depends on: terraform-authentik gitea OIDC app, and terraform-artifactapi ^gitea/ dockerhub allowlist (both separate PRs). One-time Vault seeds are listed in the migration doc.

unkinben 7a889ca326 Flip resolver forwarding for k8s zones to the in-cluster bind (#288)
## Why

Step 3 of 3 in the external-dns → in-cluster bind migration: the client-visible cutover. The `openforwarder` resolvers currently forward `k8s.syd1.au.unkin.net` to the legacy VM anycast `198.18.19.20` (a temporary measure — commit 7ee5dfb) and have NO forwarder at all for the reverse zone `200.18.198.in-addr.arpa`. Once external-dns publishes to the in-cluster `bind-externaldns` (PR 2), resolvers must read from it.

## Changes

- Repoints the `fwd-k8s-syd1-au-unkin-net` forwarder from `198.18.19.20` (legacy VM) to `198.18.200.8` (in-cluster `bind-externaldns` VIP).
- Adds `fwd-200-18-198-in-addr-arpa` forwarding `200.18.198.in-addr.arpa` → `198.18.200.8`, closing the reverse-zone gap so PTR lookups for the k8s LB range keep resolving after cutover. Modeled exactly on the existing forward-zone entries.
- Refreshes the header comment to describe the in-cluster upstream.

`kubectl kustomize apps/overlays/au-syd1/bind-internal` builds clean; both zones render with forwarder `198.18.200.8` and there is no residual `198.18.19.20`.

## Merge gate

- PR 2 (`benvin/externaldns-incluster`) merged, AND
- record parity confirmed between legacy and in-cluster for the forward zone. Spot-check (repeat for each name):
  ```
  for n in puppetca puppet puppetdb encapi pdbmux artifactapi consul; do
    echo "$n:"
    dig +short @198.18.19.20 A $n.k8s.syd1.au.unkin.net
    dig +short @198.18.200.8  A $n.k8s.syd1.au.unkin.net
  done
  # plus 2-3 PTRs in the reverse zone:
  dig +short @198.18.19.20 -x 198.18.200.8
  dig +short @198.18.200.8  -x 198.18.200.8
  ```
  A/PTR answers from `198.18.200.8` must match those from `198.18.19.20` before merging.

## Verification (after merge)

```
dig +short @198.18.200.7 A puppet.k8s.syd1.au.unkin.net   # resolvers VIP
dig +short @198.18.200.7 -x 198.18.200.8                  # reverse via resolvers
```
Resolution through the `bind-resolvers` VIP should now answer for both the forward and reverse k8s zones.

## Rollback

Revert this PR — the `fwd-k8s-syd1-au-unkin-net` forwarder returns to `198.18.19.20` and the reverse forward is removed. The legacy VM is untouched and remains authoritative until decommission.

unkinben 8eeca2d1fb Reflect externaldns TSIG key into the externaldns namespace (#285)
## Why

Step 1 of 3 in the external-dns → in-cluster bind migration. For external-dns to send RFC2136 updates to the in-cluster `bind-externaldns` primary, it must present the exact TSIG key the primary's `allow-update` accepts. The bind-operator generates that key material into Secret `externaldns-key-tsig` in `bind-internal`; reflecting it into the `externaldns` namespace removes the manual eyaml→Vault key sync and guarantees key parity.

## Changes

- Adds `spec.secretTemplate.annotations` to BindTSIGKey `externaldns-key` with the emberstack reflector hints: `reflection-allowed`, `reflection-allowed-namespaces: externaldns`, `reflection-auto-enabled`, `reflection-auto-namespaces: externaldns`.
- Regenerates `schemas/bind.unkin.net/bindtsigkey_v1alpha1.json` from the live CRD (deployed bind-operator v0.2.4 already exposes `secretTemplate` — the WIP branch's ">= v0.3.0" claim is stale) to add the `secretTemplate` property. Schema output is byte-identical to running `ci/generate-schemas.sh`.

`kubectl kustomize apps/overlays/au-syd1/bind-internal` builds clean and renders the annotations onto the BindTSIGKey.

## Verification (after merge)

```
kubectl -n externaldns get secret externaldns-key-tsig \
  -o jsonpath='{.data.secret} {.data.algorithm}{"\n"}'
```
Both `secret` and `algorithm` keys must be present (reflector mirrored the source Secret from bind-internal).

## Rollback

Revert this PR. The source Secret in bind-internal is unaffected; only the reflected mirror in `externaldns` is removed.

Merge order: this is PR 1/3. PR 2 (repoint external-dns) must not merge until the reflected secret is verified.

unkinben 39b180aec9 bind-internal: allow k8s pod network to query the resolvers (#271)
Kubernetes nodes querying the bind-resolvers LoadBalancer VIP (198.18.200.7) get REFUSED (EDE 18 Prohibited).

The service is `externalTrafficPolicy: Local`, which preserves the client source IP for traffic entering the cluster from outside — but a node querying the VIP never leaves via OSPF. Its own kube-proxy DNATs the LB IP in the OUTPUT chain and masquerades the source to a cluster-internal address (the node's flannel.1, e.g. 10.42.x.x). That address is not in `acl-main.unkin.net`, so the openforwarder view's match-clients rejects the query.

External clients preserve their real source IP and match acl-main, which is why only in-cluster hosts were affected.

Add `10.42.0.0/16` to `acl-main.unkin.net` so node-originated (masqueraded) resolver queries are permitted. This mirrors the authoritative cluster, which already allows the pod network (`allow-query { ...; 10.42.0.0/16; }`).

unkinben 7ee5dfbbcd TEMP: forward k8s.syd1.au.unkin.net to external external-dns service (#269)
The bind-resolvers `openforwarder` view forwarded `k8s.syd1.au.unkin.net` to the in-cluster bind-externaldns (198.18.200.8), which is not reliably serving those records yet, so lookups return NXDOMAIN.

Concrete impact: Gitea cannot resolve the k8s-hosted CI host, so its outbound webhook fails and tagged releases never trigger CI (e.g. cutting a new bind-operator release from a tag).

This points the `fwd-k8s-syd1-au-unkin-net` forwarder at the existing external external-dns bind service anycast **198.18.19.20** (puppet `roles::infra::dns::externaldns` — master `ausyd1nxvm2127` + slaves `2128`/`2129`, advertised via OSPF), which still holds the working `k8s.syd1.au.unkin.net` records. It is in the same 198.18.19.0/24 anycast family as the consul forwarder (198.18.19.14) the resolvers already use, so it is reachable from the pods.

Temporary measure. Revert to 198.18.200.8 once external-dns publishes to the in-cluster bind-externaldns service. Only the forward target changes; no CRD/schema changes.

unkinben 0c1156282f bind-internal: allow localhost to query the authoritative cluster (#267)
## Why

Every bind-operator dynamic update is refused (`update ... denied due to allow-query`) because the operator execs `nsupdate` against `127.0.0.1` inside the primary pod, and the BindCluster `allow-query` listed only the client subnets (`auth-acl-main`) and the pod net (`10.42.0.0/16`) — not loopback. This blocked ALL DNSRecords (identity, s3, dashboard, lb1) from ever applying.

## Change

- Add `localhost` to the BindCluster `allow-query` in `apps/base/bind-internal/authoritative/cluster.yaml`. The `client-update` TSIG key still gates the actual update.

unkinben f61d5ba16d bind-internal: add dashboard.ceph.unkin.net + lb1.unkin.net records (#266)
## Why

The cephrgw-operator (in-cluster) fails to reach the Ceph dashboard because CoreDNS/bind-internal has no record for `dashboard.ceph.unkin.net` (`no such host`). Publish it authoritatively so in-cluster clients can resolve it.

## Changes (apps/base/bind-internal/authoritative/records.yaml)

- `DNSRecord dashboard-ceph-cname`: CNAME `dashboard.ceph.unkin.net` -> `lb1.unkin.net.` (zone `ceph.unkin.net`, zoneRef `ceph-unkin-net`).
- `DNSRecord lb1-unkin-net`: A `lb1.unkin.net` -> `103.216.191.185` (zone `unkin.net`, zoneRef `unkin-net`).

Once applied, the operator's `sandbox-user`/`sandbox-bucket` (currently Error/Pending on DNS) will reconcile to Ready.

## Why

unkinben 706e30a202 bind-internal: add ceph.unkin.net authoritative zone (#260)
## Why
The ceph/halb host (`ausyd1nxvm2069`) publishes `dashboard.ceph.unkin.net` via nsupdate to a dedicated `zone ceph.unkin.net.`, which `bind-authoritative` was not authoritative for (NOTZONE). This adds the zone so that record has a home.

## Changes
- Add `ceph.unkin.net` BindZone (primary, dynamicUpdate, updateKeyRef client-update) to bind-authoritative, matching the unkin.net/main.unkin.net pattern.

## Note — not the root cause of the 6 missing hosts
Log evidence (VictoriaLogs, dns-update-apply on 2069/2070) shows the actual failure is a **host-side bug in the puppet `dns-update` script**: `fqdn()` appends the zone even to records whose name is already fully-qualified (e.g. `au-syd1-pve.main.unkin.net.`, `cobbler.main.unkin.net.`), producing a `..` empty label → `invalid owner name: empty label` → the whole main.unkin.net update `send` fails (reverse PTR, sent first, still lands). That script fix (puppet-prod) is the real blocker; this zone is still needed so the ceph record does not hit NOTZONE afterward.

unkinben 197991a6ca bind-internal: allow admin workstation to query the resolver (#259)
## Why
Follow-up to #258 (which added workstation+router to the *authoritative* ACL). The **resolver** (bind-resolvers, 198.18.200.7) has its own `acl-main.unkin.net` gating its `openforwarder` view; the workstation is not in it, so recursive queries return REFUSED. This lets the workstation use the resolver as its normal nameserver.

## Changes
- Add `10.10.12.200/32` (workstation, wireguard) to resolver `acl-main.unkin.net`
- Add `198.18.21.160/32` (router) explicitly for documentation; already covered by existing `198.18.21.160/27` and `198.18.21.0/24` (no functional change for the router)

unkinben 8f164873e0 bind-internal: allow admin workstation + router to query authoritative (#258)
## Why
Allow the operator's workstation and router to query the bind-authoritative servers directly. Their source addresses are outside the existing `auth-acl-main` client subnets, so named returns REFUSED to them today. The router sits on 198.18.21.0/24 which is not in the ACL at all.

## Changes
- Add `10.10.12.200/32` (workstation, over wireguard) to `auth-acl-main`
- Add `198.18.21.160/32` (router) to `auth-acl-main`

## Note
This grants query permission only. Reaching the LoadBalancer VIP (198.18.200.6) from off-datacenter paths is separately gated by `externalTrafficPolicy: Local`; the workstation-over-wireguard path still needs its L4 routing addressed to actually land on a node with a ready endpoint.

unkinben 421df740ea Add identity.unkin.net internal DNS record (#256)
## Why

`identity.unkin.net` is configured as the Authentik OIDC issuer but has **no DNS record anywhere**, so in-cluster OIDC discovery fails (e.g. `argocd-server` → `lookup identity.unkin.net ... no such host`). Add an authoritative A record served by the internal bind system (bind-operator) so it resolves.

## Change

- New `DNSRecord/identity-dns-internal` → `198.18.200.4` (the traefik-internal gateway VIP, where the Authentik Gateway serves the `identity.unkin.net` hostname), in the `unkin-net` zone.
- Lives in the **`bind-internal` namespace** alongside the `BindZone`: the operator resolves `zoneRef`/`clusterRef`/`updateKeyRef` within the record's own namespace, so it can't live in the app (authentik) namespace.
- Wired into `apps/base/bind-internal/authoritative/kustomization.yaml`.
- `identity-dns-internal` name distinguishes this from the external DNS that Authentik will manage its own records from later.

unkinben 8a9cdf35fd Bump bind-operator to v0.2.3 (deterministic render) (#255)
## Why

v0.2.2's config-hash rolling restart exposed a latent non-determinism: `client.List` returns cache-ordered results, so the resolver's forward zones reshuffled every reconcile, flipping the config hash and rolling `bind-resolvers-2` endlessly. v0.2.3 (bind-operator #11) sorts every rendered list so `named.conf` is byte-identical across reconciles and the hash is stable.

## Changes

- Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.3`.
- Bump the `bind-tsig-api` image (`bind-internal/tsig-api/tsig-api.yaml`) to `v0.2.3`.

CRDs are unchanged from v0.2.2 (controller-only change), so the generated kubeconform schemas need no update.

## Validation

- `bind-system` renders with the v0.2.3 CRD bundle; `bind-internal` passes `kubeconform` (56/56); pre-commit clean.

## Deploy note

On deploy the deterministic operator stops churning the ConfigMap; the config hash stabilizes and the stuck resolver rolling update completes, leaving all three pods Ready on one revision.

unkinben 1f22ec2aa7 Bump bind-operator to v0.2.2 (config-hash rolling restart) (#254)
## Why

v0.2.2 (bind-operator #10) stamps a `bind.unkin.net/config-hash` on the pod template, so a ConfigMap or `keys.conf` change flips the hash and triggers an operator-driven rolling restart. This fixes the class of bug where config edits (ACLs, forwarders, `validate-except`, primary address, TSIG rotation) never reached running pods — they held a startup snapshot and needed manual pod deletes.

## Changes

- Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.2`.
- Bump the `bind-tsig-api` image (`bind-internal/tsig-api/tsig-api.yaml`) to `v0.2.2`.

CRDs are unchanged from v0.2.1 (controller-only change), so the generated kubeconform schemas need no update.

## Validation

- `bind-system` renders with the v0.2.2 CRD bundle; pre-commit clean.

## Deploy note

When the v0.2.2 operator first reconciles it stamps the config-hash annotation, triggering **one rolling restart per bind StatefulSet** — expected, and it also pulls in any already-pending config. From then on, config changes roll pods automatically.

unkinben 69788a967c Fix validate-except syntax (resolver crash-loop) (#252)
## Why — urgent

PR #251 added `validate-except` to the resolver `BindCluster` but the list omitted the trailing semicolon after the final entry. `named` requires **every** entry in a list to be semicolon-terminated, including the last before the closing brace, so it fails config parse and the resolver pods crash-loop:

```
/run/named/named.conf:18: missing ';' before '}'
loading configuration: failure
exiting (due to fatal error)
```

The resolvers (`.7`) are down until this lands; the authoritative (`.6`/`.9`) and externaldns (`.8`) are unaffected.

## Fix

```diff
- validate-except { unkin.net; 18.198.in-addr.arpa; consul }
+ validate-except { unkin.net; 18.198.in-addr.arpa; consul; }
```

Renders to `validate-except { unkin.net; 18.198.in-addr.arpa; consul; };` — valid.

## Recovery

On merge + ArgoCD sync, the operator re-renders the ConfigMap with valid config and the crash-looping pods self-heal on their next restart (no manual `rollout restart` needed). Validated: `bind-internal` renders and pre-commit clean.

broken trust chain resolving 'ausyd1nxvm2120.main.unkin.net/A/IN': 198.18.200.6#53
query failed (broken trust chain)
```

The resolver runs `dnssec-validation auto`. The public `unkin.net` is DNSSEC-signed (the `.net` parent publishes a DS), but the in-cluster split-horizon authoritative serves `unkin.net` **unsigned**. The validator sees "parent says secure" + an insecure answer → treats it as spoofing → SERVFAIL. The authoritative works directly because it does no validation.

## Fix

Add `validate-except` (via `spec.extraOptions`) for the forwarded internal domains, so the resolver treats them as insecure and skips validation:

```
validate-except { unkin.net; 18.198.in-addr.arpa; consul }
```

- `unkin.net` covers all `*.unkin.net` (incl. `main.unkin.net`, `k8s.syd1.au.unkin.net`)
- `18.198.in-addr.arpa` covers every `NN.18.198.in-addr.arpa` reverse zone (subtree)
- `consul` covers the consul TLD

This also makes internal resolution independent of Internet egress (no DNSSEC chain-walk needed). External-name validation is unchanged. No operator change required.

## Validation

`bind-internal` renders and passes `kubeconform` (56/56); pre-commit clean.

## Activation

After merge + operator reconcile, the resolver ConfigMap re-renders; the running pods hold a startup snapshot, so they need a reload: `kubectl -n bind-internal rollout restart statefulset/bind-resolvers`.

unkinben 65f18a6380 Bump bind-operator to v0.2.1 (secondary replication fix) (#250)
## Why

v0.2.1 fixes authoritative **secondary replication**, which never actually worked — the master REFUSED the catalog AXFR. Root causes (bind-operator #9): secondaries presented no TSIG key, member zones had no `allow-transfer`, and secondaries pointed at the primary's ephemeral pod IP.

## Changes

- Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.1`.
- Bump the `bind-tsig-api` image (`bind-internal/tsig-api/tsig-api.yaml`) to `v0.2.1`.

CRDs are unchanged from v0.2.0, so the generated kubeconform schemas need no update.

## Validation

- `bind-system` renders with the v0.2.1 CRD bundle; `bind-internal` passes `kubeconform` (56/56); pre-commit clean.

## Deploy note

Existing member zones pick up `allow-transfer` via `modzone`, and secondaries re-point at the stable primary Service ClusterIP with the transfer key, restoring replication without manual BIND surgery. A from-scratch namespace recreate also comes up clean (OrderedReady startup means secondaries snapshot a ClusterIP-correct config). Caveat for a full recreate: the operator regenerates the `client-update` TSIG key, so its new material must be re-synced into puppet eyaml before clients can nsupdate.

unkinben 38ef6c4a09 Bump bind-operator to v0.2.0 and deploy companion TSIG API (#249)
## Why

bind-operator v0.2.0 adds the `BindTSIGAPI` CRD and a companion API that `vault-plugin-secrets-bind-tsig` calls to create, rotate and delete TSIG keys (it does so by managing `BindTSIGKey` resources, which the operator reconciles into key material). This rolls the operator forward and deploys an API instance so Vault never talks to the Kubernetes API directly.

## Changes

- Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.0`.
- Broaden the operator ClusterRole (`bind-system/rbac.yaml`) with `deployments`, `serviceaccounts` and `roles`/`rolebindings`, so the `BindTSIGAPI` reconciler can create the API Deployment and its namespaced Role/RoleBinding.
- Add a `BindTSIGAPI` (`bind-tsig-api`) in `bind-internal`; the operator reconciles it into a Deployment, Service, ConfigMap, master-token Secret and RBAC. Keys are created in `bind-internal`, alongside the authoritative cluster and its existing keys.
- Add the generated kubeconform schema for `BindTSIGAPI`.

## Notes

- The master access token Secret (`bind-tsig-api-token`) is generated by the operator when absent; the operator does not own it, so a `VaultStaticSecret` can later pre-seed/overwrite it to source the token from Vault.
- Validated: both overlays render (`kubectl kustomize`) and pass `kubeconform` (bind-internal 56/56 valid); pre-commit clean.

## Follow-up

- Point `vault-plugin-secrets-bind-tsig` config at `http://bind-tsig-api.bind-internal.svc:8443`.

unkinben 05d2c83258 Authoritative zones: accept puppet client dynamic updates (#244)
Enables per-host RFC2136 updates from puppet (puppet-prod #475 profiles::dns::updater) to the bind-authoritative zones, via the .9 write endpoint.

## Changes
- add **client-update** BindTSIGKey (clusterRef bind-authoritative; operator generates the material into Secret client-update-tsig)
- set `dynamicUpdate: true` + `updateKeyRef: client-update` on all **18** authoritative zones → the operator renders `allow-update { key "client-update"; }`

## Key bridge (manual, per the TSIG plan)
The operator generates the client-update key value; it must reach puppet eyaml (`profiles::dns::updater::key_secret`) for clients to authenticate — until the planned Vault-sync/secret-reflection operator features exist. Get it with:
`kubectl -n bind-internal get secret client-update-tsig -o jsonpath='{.data.secret}' | base64 -d`

## Validated
kustomize build + kubeconform.

unkinben e030f07986 Add primary (write) Services to authoritative + externaldns (#229)
**Stacked on #228** (needs operator v0.1.5). Merge #228 first; the diff collapses to just this after.

## Why
Writes (RFC2136/nsupdate) must go to pod-0 — the round-robin read Service would land them on a secondary (rejected). Adds a dedicated write endpoint per cluster (operator v0.1.5 `primaryService`).

## Changes
- `bind-authoritative`: LoadBalancer write endpoint on **198.18.200.9** (`bind-authoritative-primary`)
- `bind-externaldns`: ClusterIP write endpoint (`bind-externaldns-primary`, for in-cluster writers)
- regenerate the bindcluster kubeconform schema (primaryService + externalTrafficPolicy)

## Deferred
external-dns is **not** repointed at `bind-externaldns-primary` yet: it authenticates with the existing TSIG key, which the operator-generated key won't match until the planned Vault-sync + secret-reflection features exist. Until then external-dns keeps writing to the puppet externaldns.

## Validated
kustomize build + kubeconform (3 BindClusters valid against the v0.1.5 schema).

unkinben 3ab8bcc34b Restrict authoritative queries to internal networks (#227)
Mirrors the puppet authoritative `master-zones` view (match-clients `acl-main.unkin.net`, recursion no) — restricting who can query bind-authoritative.

## Changes
- add `auth-acl-main` BindACL with the puppet authoritative acl-main.unkin.net networks (13-17,19,20,24-29)
- `allow-query { auth-acl-main; 10.42.0.0/16; }` on bind-authoritative via extraOptions

## Notes
- Implemented as a global `allow-query` rather than a BindView: dynamic *primary* zones inside a view would need per-view `allow-new-zones` (an operator gap). Functionally equivalent for the single master-zones view.
- `10.42.0.0/16` (pod network) is included so secondaries can SOA-refresh from the primary during catalog replication — without it, replication breaks.
- Works on the current operator (no HOLD).

## Caveat
The DNS Services use externalTrafficPolicy: Cluster, which SNATs external clients to node IPs (198.18.19.x, already in acl-main), so this ACL doesn't truly restrict *external* clients yet. True source-IP restriction needs externalTrafficPolicy: Local — happy to switch if wanted.

unkinben c8d61205ce Configure resolvers like puppet (openforwarder view + forward zones) (#226)
## Why
`dig google.com @198.18.200.7` was refused: the resolver never set allow-recursion, so BIND defaulted to localnets/localhost. This mirrors the puppet resolver (/etc/named/views.conf + acls.conf) exactly.

## Changes
- `openforwarder` BindView: `match-clients` = the 4 internal ACLs, recursion yes, allow-recursion/allow-query `any` (match-clients gates)
- 4 BindACLs from puppet acls.conf (acl-main.unkin.net/acl-dmz/acl-common/acl-nomad-jobs)
- 26 conditional forward zones in the view (unkin→198.18.19.15, consul→.14, k8s→.20, dmz/network/prod + 10.10.x reverse → 10.10.16.32/33)
- global forwarders 8.8.8.8/1.1.1.1
- operator image → v0.1.4

## Note
Forward-zone upstreams point at the **puppet anycast** servers (still authoritative during migration); flip to the in-cluster authoritative/externaldns LBs once zone data is migrated.

## Validated
kustomize build (59 docs), kubeconform clean.

unkinben ce8ebc71ce Consolidate BIND DNS into one bind-internal namespace (#225)
**HOLD until v0.1.3 is tagged/built** (operator #4 merged + tagged) — this PR bumps the operator to v0.1.3, whose CRD adds the `clusterRef` field these keys use.

## Why
Put all BIND DNS services in one `bind-internal` namespace and name the StatefulSets clearly.

## Changes
- 3 clusters consolidated into `bind-internal`, StatefulSets renamed **bind-authoritative** / **bind-resolvers** / **bind-externaldns**; LBs kept on 198.18.200.6/.7/.8; external-dns hostnames renamed to match
- `clusterRef` added to `transfer-key` (→ bind-authoritative) and `externaldns-key` (→ bind-externaldns) so keys are scoped per cluster
- removed the old `ns-auth`/`ns-resolver`/`ns-externaldns` apps; ApplicationSet + AppProject now list `bind-internal`
- bumped `bind-system` operator to **v0.1.3** (CRD link + image)
- operator stays in `bind-system`

## Deploy impact
ArgoCD prunes the old ns-* namespaces (StatefulSets/PVCs — data is only seed SOA+NS, no migrated records yet) and creates the renamed clusters in bind-internal.

## Validated
`kustomize build` → 28 docs (3 BindCluster, 20 BindZone, 2 catalog, 2 keys, ns); kubeconform clean.
