The chart has been deployable by hand since #25 and linted in CI since #168;
this makes a merged PR actually ship it to the lab server's Talos VM.

Neither the Kubernetes API nor the in-cluster registry is publicly reachable,
so the job forwards 6443, 30500 and 30141 over the same SSH hop into the Fedora
host that the Gitea-runner pipeline uses. That splits the registry into two
names for one store: images are pushed through the tunnel to localhost:30500,
and the node pulls them from its own NodePort — the address its registry-mirror
patch trusts over plain HTTP.

It deploys with `make k8s-reseed` rather than `make k8s-up`: the bootstrap Jobs
are idempotent, and deleting them first is what stops a changed Job template
from wedging `helm upgrade`. The nine deployments are then rolled explicitly,
because `dev` is a mutable tag and helm sees an unchanged pod template.

PR CI is the merge gate, so this workflow does not re-run the checks. Deploys
queue instead of cancelling: a `helm upgrade` killed half-way leaves the release
in `pending-upgrade` and needs unwedging by hand.

not 9d7e8e5b65 ci(k8s): gate the Helm chart in CI + a compose↔chart drift check (closes #168) (#171)

## What & why

The Helm chart landed in #167 with two gaps written into ADR-0033: `make k8s-lint` existed
but no CI job ran it, and *"a second deployment description to keep in step with compose —
nothing enforces that today; a drift check belongs in CI (follow-up)"*. Both are closed here.

**`make k8s-drift`** (`infra/helm/check-drift.py`, stdlib only) compares what each stack
actually deploys rather than diffing two files that differ by design: workload names and
resolved container images, taken from `docker compose config --format json` and a rendered
chart. The six differences that exist today are declared in `DEVIATIONS` with the reason
each was forced — the four `*-init` Django services folded into their web pods, and the two
bootstrap Jobs compose runs from the host — so only a *new* difference fails.

**A `k8s` CI job** runs `k8s-lint` then `k8s-drift` on every push and PR. No cluster, no
marketplace action: helm is fetched as the pinned static binary the Talos runbook already
gives developers.

Closes #168

## Definition of Done

- [x] Linked Gitea issue (above).
- [x] Failing test committed before the implementation — the red commit reports all six
      real differences; the green commit declares them.
- [x] Implementation makes the test pass.
- [x] Conventional Commits referencing the issue (`refs #168`).
- [x] CI green — awaiting the run on this PR (`make k8s-lint` and `make k8s-drift` pass locally).
- [x] `docker compose up` unaffected — no service, image or compose file is touched.
- [x] Docs updated — `docs/runbooks/ci.md` (job table + the one place local and CI now
      differ), `docs/runbooks/kubernetes-talos.md` §7/§"not ported", and ADR-0033's cost note.
- [x] No ADR needed: no new dependency (python stdlib, and helm/docker were already
      prerequisites of the `k8s-*` targets), no boundary moved, no §8 rule bent.
- [x] Not user-visible, so no demo note.

## Notes for reviewers

Verified by hand that both drift classes fail the check, not just that it passes today:

- bumping `OPENZAAK_TAG` in compose alone → reports `openzaak` and `oz-celery` with both
  image strings;
- adding a workload to `values.yaml` alone → reports it by name.

Deliberate limits (there is a `ponytail:` note in the script):

- **Names and images only**, as sets — no per-workload env, ports or volumes. Those differ
  by design in four documented places, so comparing them would mean re-encoding every
  deviation field by field for very little more signal.
- **The three observability workloads are rendered with `enabled=true`** by the check, even
  though both stacks default them off, so their images can't drift unwatched.
- **`k8s-lint`/`k8s-drift` are not in `make ci`**, to avoid making `helm` a hard
  prerequisite for everyone. That is now the only local/CI difference; it's called out in
  `docs/runbooks/ci.md`.

Follow-ups filed while reviewing the chart, not addressed here: #169 (the published docs
omit every ADR after 0010 and all runbooks but `ci.md`) and #170 (the production-posture
ADR #25 asked for — secrets are still plain text in `values.yaml`).Reviewed-on: #171

## What & why

Two changes, made and verified together on a real cluster.

**S-24 / #25 — a Helm chart for the platform.** One chart, `infra/helm/big-reference`,
whose `values.yaml` is a near-literal transcription of `infra/docker-compose.yml`, rendered
by three generic templates (Deployment, Job, Service) over a `workloads` map. Adding a
service is a values edit. `make k8s-lint` renders and schema-checks the whole stack without
a cluster. The issue asked for a *sketch*; this is deployed and verified end to end (see
below), which is more than it asked for — the part it asked for that is **not** here is the
production-posture write-up (HA, secrets, backup), see Known gaps.

**#166 — Caddy replaces nginx in the portals.** nginx resolves a variable `proxy_pass`
upstream itself, using only the `resolver` directive and never `/etc/resolv.conf`'s search
domains. That had cost two workarounds in one script: rewriting the resolver address for
rootless podman, and injecting a full FQDN so the bare `bff` name could resolve on
Kubernetes. Caddy dials per request through the system resolver, so `reverse_proxy
bff:8080` works on every engine unchanged; `apps/portal-nginx-resolver.sh` and the chart's
`BFF_HOST` env are deleted.

Closes #25
Closes #166

## Definition of Done

- [x] Linked Gitea issue (above).
- [x] Failing test committed before the implementation — twice: the Caddyfile contract test
      before the Caddyfiles, `make k8s-lint` before the chart.
- [x] Implementation makes the test pass.
- [x] Conventional Commits referencing the issues (`refs #25` / `refs #166`).
- [ ] CI green — awaiting the run on this PR (`make k8s-lint`, `dotnet format` and the new
      unit self-check pass locally; the compose e2e and mutation lanes are CI's).
- [ ] `docker compose up` from a fresh clone reaches green health checks within 3 minutes —
      the portal images were rebuilt and verified standalone, but a full `make up` run has
      not been done on this branch. Please confirm in review or let CI's smoke test speak.
- [x] Docs updated — `docs/runbooks/kubernetes-talos.md` (new), `frontend-decisions.md`,
      `demo-script.md`, and the docs that named nginx.
- [x] ADR added — ADR-0033 (chart) and ADR-0034 (Caddy).
- [ ] Demo note in `docs/demo-script.md` — not added: the deployment target is not a
      user-visible slice, and the Caddy swap is invisible to the demo script beyond the
      wording fix included here.

## How it was verified

Brought up from scratch on a single-node Talos v1.14.0 VM (6 vCPU / 10 GB, virtio disk)
under virt-manager: **29 pods ready and four bootstrap Jobs complete in under three
minutes, zero restarts**, using ~4.4 GB of the VM's 10 GB.

- Full Common Ground path: portal Caddy → BFF → domain → Flowable → ACL → OpenZaak +
  Objecten → NRC → event-subscriber → projection → public register (`INGEDIEND`, reference
  matching the submitted registration).
- Werkbak read with an MFA'd medewerker token → 200.
- The browser flow driven with Playwright against `http://localhost:30140`: secure context,
  `crypto.subtle` present, Keycloak form reached, login completed, **no console errors**.
- Routing checked against a stub BFF: SPA fallback serves deep links, each portal proxies
  its own groups, and a portal does *not* proxy a neighbour's group.

## Notes for reviewers

Three bugs this shook out, each fixed at the cause rather than the symptom:

1. **`command` vs `args`.** Compose's `command:` replaces the image CMD; Kubernetes'
   replaces the ENTRYPOINT. Transcribing one to the other broke every upstream image that
   relies on its entrypoint — postgres refused to run as root, Keycloak tried to exec
   `start-dev`. The chart now `fail`s at render time on `command`.
2. **Concurrent migrations.** Both `/setup_configuration.sh` and `/start.sh` run
   `manage.py migrate`; compose serialises them with `depends_on`, Kubernetes has no such
   edge, so the init Job and its web pod raced (`relation "zgw_consumers_service" already
   exists`). The four Django services now do both steps in order in the web pod — which
   also deletes four workloads.
3. **`emptyDir` databases are wiped by any pod-template change.** `make k8s-reseed` now
   also restarts `event-subscriber` and `projection-api`, which create the projection
   schema on start and otherwise keep writing to a schema-less database.

Known gaps / follow-ups:

- **Secrets.** `values.yaml` carries the dev credentials in plain text (`admin/admin`, the
  ZGW client secret, the two Objecten tokens) and the chart has no `Secret` objects. Fine
  for a laptop demo, and exactly what #25's "production posture" ADR should address — I
  suggest a follow-up issue rather than stretching this PR.
- **No CI gate for the chart yet.** `make k8s-lint` exists but is not wired into
  `.gitea/workflows/ci.yaml`, and nothing enforces that the chart and the compose file stay
  in step. Worth a small follow-up.
- **This is two slices in one PR.** They were built and verified together and the diff is
  entangled (the chart was written against Caddy from the start), so splitting now would
  mean re-creating an nginx-shaped chart to throw away. Happy to split if you'd rather.
- **Rebased onto #161** (merged as #165) rather than merged, to keep the history linear.
  One conflict, in the `unit:` target where both branches add a self-check line — resolved
  by keeping both. #161's `infra/host-browser.yml` arrived with
  `/usr/share/nginx/html/config.json` and is fixed to `/usr/share/caddy/` inside the
  `feat(portals)` commit, so no commit on this branch leaves that overlay pointing at a
  path the images no longer have.Reviewed-on: #167
