unkin-agent 76da30d2f7 arrstack: set *arr UrlBase=/<app> for path-based proxy hosting (#378) 
## Why
arrproxy forwards `arrstack.unkin.net/<app>/...` to each *arr Service **preserving** the `/<app>` prefix. Without a matching `<UrlBase>` the apps 307-redirect to `/`, breaking path-based hosting. Prerequisite for arrproxy path routing (PR #377... arrproxy service account added in #376).

## Change
Extend the existing idempotent `apikey-init` init container in sonarr/radarr/prowlarr to also enforce `<UrlBase>/<app></UrlBase>` in `/config/config.xml` (sonarr=/sonarr, radarr=/radarr, prowlarr=/prowlarr):

- Set/replace `<UrlBase>` if present, insert after `<Config>` if absent, or write both `<ApiKey>` + `<UrlBase>` when creating a fresh config. `<ApiKey>` handling is unchanged.
- Because Servarr moves all routes (including `/ping`) under the URL base, update liveness/readiness probes from `/ping` to `/<app>/ping` so they don't 404 once UrlBase is set.

nzbget is not fronted by arrproxy and is left untouched.

## Validation
- `kustomize build --enable-helm apps/overlays/au-syd1/arrstack` succeeds
- `pre-commit` (yamllint etc.) passes

unkin-agent cd8e2c262f deploy arrproxy (oauth2-gated *arr proxy + per-user API keys) (#377) 
Deploys arrproxy v0.1.0 (task 9 final integration) into the existing `arrstack` app: the external, Authentik-gated front door for sonarr/radarr/prowlarr with per-user API-key brokering. Manifests are wired to match the arrproxy v0.1.0 code (ports, routes, identity headers, keys dir), mirroring the ghp/artifactapi estate patterns.

## Topology (`apps/base/arrstack/arrproxy/`)
- **oauth2-proxy** Deployment + Service `arrproxy` is the single front (OIDC against the Authentik `arrstack` app). It path-routes via `--upstreams` to:
  - `arrproxy-ui` for `/` and static SPA assets,
  - `arrproxy-api` for `/api/*` (token API) and `/sonarr|/radarr|/prowlarr` (the *arr proxy).
  - `--skip-auth-regex=^/[^/]+/api` bypasses oauth **only** for the *arr proxy API (`/sonarr/api...`), while `/api/tokens`, `/api/me` and the UI stay authenticated.
- Identity+groups reach the api via `--pass-user-headers` (`X-Forwarded-{User,Email,Groups}`). The api reads `ARRPROXY_GROUPS_HEADER=X-Forwarded-Groups` — `--set-xauthrequest` only populates auth_request *response* headers and never reaches an `--upstreams` backend, so it is intentionally not used.
- oauth2-proxy trusts `identity.unkin.net` (internal Vault-PKI CA) via a `combine-certs` initContainer (system roots + `vault-ca-cert`), same pattern as artifactapi.

## Data + secrets
- **CNPG** token store `arrproxy-db` (2 instances, cephrgw S3 backups + nightly ScheduledBackup). arrproxy-api does **not** self-migrate, so a wave-1 ArgoCD `Sync` hook Job applies `migrations/0001_init.sql` (mirrored into a ConfigMap) as the CNPG app user. DSN built from the generated `arrproxy-db-app` Secret.
- **VaultStaticSecrets** (arrstack `default` SA / templated role — no terraform-vault change): `arrproxy-pepper` (seeded) and `oauth-credentials`. The three real *arr keys are **reused** from the existing `<app>-apikey` Secrets, projected one file per app into `/etc/arrproxy/keys`.

## Exposure
- **Gateway** `traefik-external`, hostname `arrstack.unkin.net`, cert-manager `vault-issuer` TLS (`arrproxy-gateway-tls`); HTTPRoute → the oauth2-proxy entry Service (+ HTTP→HTTPS redirect).
- Adds the `arrstack.unkin.net` apex A record → external DMZ VIP `198.18.199.0` to the bind-operator `unkin.net` zone (`apps/base/bind-internal/authoritative/records.yaml`), mirroring the ghp/identity apex records.

## Validation
- `kustomize build --enable-helm apps/overlays/au-syd1/arrstack` renders cleanly; `kubeconform` = 51/51 valid; `pre-commit` passes (no plain Secrets).

## Prerequisites / flags for end-to-end function (NOT in this PR)
- **(a)** Each *arr must run with `UrlBase=/<app>` (path-based hosting) — arrproxy preserves the `/<app>` prefix upstream.
- **(b)** The Authentik `arrstack` OIDC app (terraform-authentik PR #18) must be applied, with redirect URI `https://arrstack.unkin.net/oauth2/callback` registered and the `ak_groups` scope emitted. Confirm the discovery slug matches `OAUTH2_PROXY_OIDC_ISSUER_URL` (`https://identity.unkin.net/application/o/arrstack/`).
- **(c)** Browser XHR to `/<app>/api` is oauth-**bypassed** (skip-auth-regex), so the SPA-driven proxy calls that rely on the session (no per-user token) will not carry identity on that path — expected per the arrproxy trust model; token-based *arr clients are unaffected.
- **NetworkPolicy:** the arrproxy-api Service is not exposed via any HTTPRoute and the api strips forged identity headers in-code, but the README recommends a NetworkPolicy restricting api ingress to oauth2-proxy. The estate currently has **zero** NetworkPolicies, so one was not added here to avoid being the first (and risking probe breakage) before the CNI’s policy/probe behavior is confirmed — flagged as follow-up hardening.
- Please confirm: CNPG size (2 instances / 10Gi), backups on, hostname/VIP, and UI theme.

ARRPROXY_PEPPER was seeded via the agents AppRole at `kv/kubernetes/namespace/arrstack/default/arrproxy-pepper` (key `pepper`).

unkin-agent 31c5ca10e2 arrstack/nzbget: fix nonexistent image tag v26.2 -> version-v26.2 (#370) 
The nzbget pod in namespace `arrstack` is stuck in `Init:ImagePullBackOff`.

## Why
The deployment pins `artifactapi.k8s.syd1.au.unkin.net/dockerhub/linuxserver/nzbget:v26.2` on both the `seed-config` initContainer and the main `nzbget` container. linuxserver does not publish a bare `v26.2` tag - the pull fails with:

```
failed to resolve reference ".../linuxserver/nzbget:v26.2": ... not found
Error: ImagePullBackOff
```

Confirmed against the artifactapi dockerhub mirror: `manifests/v26.2` -> HTTP 404. linuxserver version-pins nzbget under the `version-v<MAJOR>.<MINOR>` scheme, and the immutable date tags `26.2.<date>`. `manifests/version-v26.2` -> HTTP 200.

## Change
- Set both nzbget images (initContainer + main container) to `version-v26.2`, keeping nzbget on the intended 26.2 line and matching the version-pin convention used by the sibling sonarr (`4.0.19`) / radarr (`6.3.0`) deployments.

No other change. The `seed-config` init logic is unaffected - it already mirrors linuxserver's own init (`cp /app/nzbget/share/nzbget/nzbget.conf /config/nzbget.conf`), and since it seeds `/config/nzbget.conf` before the main container, linuxserver's init copy is skipped (no conflict). Instant-move download layout on the media PVCs is preserved.

## Validation
- `kustomize build --enable-helm apps/overlays/au-syd1/arrstack` renders cleanly (both images -> `version-v26.2`, no stale `v26.2`).
- `pre-commit run --files apps/base/arrstack/nzbget/deployment.yaml` passes (yamllint et al).

Scoped to `apps/base/arrstack/nzbget/deployment.yaml` only; the top-level `apps/base/arrstack/kustomization.yaml` was not touched (another agent is editing sonarr/radarr/prowlarr on a separate branch).

unkin-agent d387301d6b arrstack: manage sonarr/radarr/prowlarr API keys via Vault (#369) 
## Why

The sonarr/radarr/prowlarr images self-generate an API key into
/config/config.xml on first boot, so the key is unmanaged and differs per
volume reset. This makes Vault the source of truth for those keys (override
bootstrap, chosen by Ben): the key is minted in Vault and enforced into
config.xml before each app starts.

## Changes

- Add a `VaultAuth` `default` in the `arrstack` namespace (kubernetes auth,
  mount `k8s/au/syd1`, role `default`, SA `default`), mirroring jellyfin.
- Add a per-app `VaultStaticSecret` that syncs
  `kv/kubernetes/namespace/arrstack/default/<app>` (key `apitoken`) into the
  `<app>-apikey` Secret. The `default` k8s role's templated policy already
  grants read on that path for the `arrstack/default` SA, so no
  terraform-vault change is needed.
- Add an `apikey-init` initContainer to each of the three deployments that
  reads `API_KEY` from the VSO-created Secret, fails closed on a missing or
  non-hex value, and writes/updates only the `<ApiKey>` element in
  `/config/config.xml` (then fixes ownership 1000:1000, mode 600). Image is a
  pinned busybox via artifactapi to keep this PR atomic (no new image
  dependency).
- Wire the new manifests into the base and per-app kustomizations.

## Notes

- Keys already seeded in Vault at `kv/kubernetes/namespace/arrstack/default/<app>`.
- nzbget is out of scope: it has no config.xml `<ApiKey>` (uses ControlPassword),
  a separate follow-up.
- Downstream consumers (proxy, terraform) currently read
  `kv/service/media-apps/<app>`; the authoritative key now lives at the path
  above. Reconciliation is deferred.

unkin-agent fc08f1fecc arrstack: sonarr/radarr/prowlarr/nzbget on shared CephFS media (#366) 
## Why
Stands up the download-automation stack (sonarr, radarr, prowlarr, nzbget) in a new `arrstack` namespace, sharing the same CephFS TV/movies subvolumes that jellyfin serves read-only (jellyfin static-PV rework is on the base branch, PR #237). Downloads and libraries live on one filesystem per media type so the arrs import with atomic hardlink moves.

## Changes
- Add `apps/base/arrstack/` namespace with its own static CephFS PVs (`arrstack-media-tv`, `arrstack-media-movies`) + RWX PVCs (`media-tv`, `media-movies`) bound to the same rootPaths jellyfin uses; each namespace gets a unique PV name/volumeHandle pinned by claimRef.
- Deploy sonarr (mounts media-tv RW), radarr (media-movies RW), prowlarr (config only), nzbget (both media PVCs RW); single replica, Recreate strategy, LinuxServer images via artifactapi dockerhub remote, PUID/PGID/TZ, probes, fsGroup for CephFS writability.
- Per-app config PVCs on `cephrbd-fast-retain` (RWO, 5Gi) for the SQLite state; internal-only Gateway + HTTPRoute per app (traefik-internal, vault-issuer, external-dns `<app>.k8s.syd1.au.unkin.net`), no oauth yet.
- nzbget: initContainer seeds `/config/nzbget.conf` (copy image template if absent, append managed path/category block once) and creates the media dirs; category `tv` -> `/media/tv/downloads`, `movies` -> `/media/movies/downloads`.
- Wire ArgoCD: add `apps/overlays/*/arrstack` to the media ApplicationSet. (media AppProject already gains the arrstack destination + PersistentVolume whitelist on the base branch.)

## Depends on
terraform-artifactapi PR #31 (allowlist `^linuxserver/` on the dockerhub remote) must be merged + applied before these pods can pull.

## Follow-up (terraform)
Root folders (/media/tv/series, /media/movies/films), download-client wiring (host `nzbget`, port 6789, categories tv/movies) and API keys are configured later via terraform-arr.
