## Why
Turns on right-sizing telemetry for the whole estate. Adds a `VerticalPodAutoscaler` with `updateMode: "Off"` (recommendation-only, advise mode) for every Deployment and StatefulSet in `apps/base`. Off mode never evicts or mutates pods, so this is purely observational: the VPA recommender (added in the vpa-system PR) publishes suggested requests/limits in each VPA's status, and nothing acts on them until someone deliberately flips a mode.
## Changes
- Add one `vpa.yaml` per app under `apps/base/<app>/` containing a `<workload>-vpa` VerticalPodAutoscaler for each workload, and register it in that app's `kustomization.yaml`.
- Coverage: 17 workloads across 11 apps.
- age-api (age-api), artifactapi (api, redis, ui), authentik (redis), bind-system (bind-operator), cephrgw-system (cephrgw-operator), encapi (encapi), kanidm (kanidm StatefulSet), litellm (litellm, redis), paperclip (paperclip), pdbmux (pdbmux), puppet (puppetboard, puppetdb, puppetserver-compiler, puppetserver-master).
## Skipped (intentionally)
- **CNPG `Cluster` objects** (artifactapi, authentik, encapi, grafana, litellm, paperclip, puppet, woodpecker) — Postgres is managed by CloudNativePG, not a VPA target.
- **CronJobs** (puppet g10k/generate-types, reposync x4) — not VPA-able.
## HPA / VPA caveat
api, ui (artifactapi), litellm, and all four puppet deployments also carry an HPA. With `updateMode: "Off"` there is no conflict today (VPA only recommends). VPA objects targeting these carry an inline comment: do **not** flip to `Auto`/`Initial` while the HPA still autoscales on CPU/memory, or the two controllers will fight over the same resource. Move the HPA to a custom/non-resource metric first.
## Verification
- `kubectl kustomize` over every touched overlay: 9/11 overlays PASS rendering all their VPAs; 2 failures are pre-existing and unrelated to this change — `authentik` fails on a local helm-tooling flag error identically on origin/main, and `paperclip` has no `apps/overlays/au-syd1/paperclip` directory yet. Both apps' base kustomizations build clean and render their VPA.
## Merge gate
- **Requires the vpa-system CRDs PR (argocd-apps #281) to merge first.** These manifests use `autoscaling.k8s.io/v1 VerticalPodAutoscaler`; without the CRDs installed, ArgoCD sync fails on an unknown kind.

## Why
During the VM -> k8s Puppet migration, two PuppetDBs coexist and nodes move
between them as they migrate. `node-lookup` (and `pblastreport`) need a single,
consistent PuppetDB v4 view spanning both. `pdbmux` is a small merging proxy
that provides exactly that. Per the all-in-kubernetes estate direction it runs
as an in-cluster service, not a per-VM systemd unit.
pdbmux now lives in its own repository (https://git.unkin.net/unkin/pdbmux) —
split out of the earlier node-lookup prototype — and is released as a container
image on its own `v*` tags.
## Changes
- Add `apps/base/pdbmux/` (namespace, configmap, deployment, service, gateway,
httproute), modeled directly on the encapi app.
- Deployment: 2 replicas, image `git.unkin.net/unkin/pdbmux:v0.1.0`, port 8080,
`/healthz` liveness + readiness, config via `PDBMUX_*` env from a ConfigMap.
- Backends: `old=http://puppetdbapi.service.consul:8080`,
`new=http://puppetdb.puppet.svc.cluster.local:8080` (in-cluster, verified
against `apps/base/puppet/service_puppetdb.yaml` port `pdb-http`/8080 — the
in-cluster address is preferred over the external gateway). `new` is
primary/prefer, merge = freshness.
- Expose over HTTPS at `pdbmux.k8s.syd1.au.unkin.net` via a `traefik-internal`
Gateway (cert-manager `vault-issuer`, external-dns), plain-HTTP backend on a
port-80 Service — same shape as the puppetdb/encapi gateways — so
VM/workstation `node-lookup` can reach it.
- Add `apps/overlays/au-syd1/pdbmux/` and wire pdbmux into the platform
ApplicationSet (`apps/overlays/*/pdbmux`) and the platform AppProject
(`pdbmux` namespace destination), exactly as encapi is wired.
No new woodpecker ServiceAccount is required: the pdbmux image push uses the
`docker-buildx` plugin against the Gitea registry with the `default` SA (same as
encapi), not artifactapi.
## Verification
- `kubectl kustomize apps/overlays/au-syd1/pdbmux` builds clean (image resolves
to `git.unkin.net/unkin/pdbmux:v0.1.0`).
- ApplicationSet + AppProject YAML validated.
## Merge gates
1. The pdbmux repo initial-content PR
(unkin/pdbmux#1) must merge first.
2. `v0.1.0` must then be tagged on the pdbmux repo so the image
`git.unkin.net/unkin/pdbmux:v0.1.0` is built and pushed by that repo`s
`.woodpecker/docker.yaml`.
3. Then merge this PR. (If the first release tag differs from `v0.1.0`, update
the image tag in `apps/base/pdbmux/deployment.yaml` to match before merging.)
