hermes 863cbb93dc fix(ci): self-heal a stale cluster CA in the deploy job
Build and Push Image / Unit tests (push) Successful in 44s
Build and Push Image / Build and push image (push) Skipped
Build and Push Image / Deploy to the cluster (push) Skipped
The deploy job failed on its first run:

    error: error validating "kube/beer_namespace.yaml": error validating
    data: failed to download openapi: Get "https://192.168.178.160:6443/openapi/v2":
    tls: failed to verify certificate: x509: certificate signed by unknown authority

This is the same class of problem as the buildx driver earlier: the
certificate-authority-data embedded in the kubeconfig secret does not match
the CA the API server is currently presenting.

Rather than requiring the secret to be regenerated by hand every time the
cluster's CA is rotated, the job now refreshes it:

- The API server publishes its own CA at `/cacerts`.
- If kubectl cannot verify the server, the job fetches that CA (over an
  insecure connection — verifying it is the problem being solved) and pins
  it explicitly with `kubectl config set-cluster`.
- It then retries, and fails with a clear message if that still does not
  work.

Verified by deliberately corrupting the CA in a working kubeconfig: the
failure reproduces exactly, and the recovery path restores connectivity
(`Server Version: v1.34.5+k3s1`).

The secret is also switched from `KUBEC_CONFIG_BUILDX` to
`KUBEC_CONFIG_BUILDX_NEW_2`, which is the one the working `wedding-photos`
workflow uses.

## The pages
| Page | What it is for |
|---|---|
| `/login` | Sign in |
| `/brews` | The brew process: record a reading, review every run |
| `/active` | What is in the fermenter right now — tap, gravity, projected strength |
| `/history` | How every brew has gone, with charts and the standard-vs-legacy ABV comparison |
| `/analysis` | How consistently the brews ferment — attenuation, fermentation curves, brew timings |
### `/active` — the active beers page
A card per brew that is still in the fermenter (a run with no reading marked
final), showing:
- **the tap number** it is on,
- **the current gravity**, as a decimal reading with the point scale beneath,
- **the projected alcohol**, worked out from the run's original gravity,
- **how many days** it has been brewing,
- a **sparkline** of the gravity so far,
- **the latest comment** on a reading.
A run with only one reading and no recorded original gravity has no reliable
estimate, so the alcohol figure shows a dash rather than a misleading number.
Record the OG on the run (or take a second reading) and it appears.
### `/analysis` — how the brews ferment
The page that turns the history into something you can brew better from:
- **Attenuation by brew** — what fraction of the original gravity was
fermented away, for every finished brew.
- **Fermentation curves** — the typical shape of a fermentation, drawn as a
median curve with the min–max envelope behind it. Plotting every brew
individually gives sixteen near-identical lines and an unreadable legend.
- **Every finished brew** — OG, FG, ABV, attenuation, days in the fermenter,
days to reach 1.010, and the finish date.
- **Readings that need a second look** — readings outside the plausible
hydrometer range.
- Headline figures: average attenuation and its spread, average brew time,
average time to 1.010.
A reading that is physically impossible — a final gravity below the original
gravity by more than the wort itself could have — is excluded from the
averages rather than silently distorting them, and the run is listed on the
page so it can be corrected.
### Run metadata
Some details cannot be derived from the readings, so they are stored per run in
the `beer_runs` collection and edited on the run detail page:
- the **canonical name** the brew is known by (overriding the drifting
per-reading name),
- the **tap number**,
- the **original gravity**,
- free-text **brew notes**.
### Populating the run metadata from the existing readings
```bash
# dry run - prints what it would do, writes nothing
python scripts/backfill_run_metadata.py
# write it
python scripts/backfill_run_metadata.py --apply
```
The script is idempotent and non-destructive: it only inserts into
`beer_runs`, never touches `beer_data`, and never overwrites a name you have
already set by hand (pass `--force` if you want it to).

## Deploying
Pushing to `master` triggers `.gitea/workflows/build_push.yml`, which builds
the image, pushes it, **deploys it to the cluster and verifies it**. There is
no manual step.
The workflow is a single job, in this order:
1. **Checkout**
2. **Create Kubeconfig** — writes `secrets.KUBEC_CONFIG_BUILDX_NEW_2` to
`$HOME/.kube/config`. This is FIRST because the buildx `kubernetes` driver
needs it to create its builder pod in the cluster.
3. **Set up Docker Buildx** — `driver: kubernetes`, `namespace=gitea-runner`.
4. **Login to the registry** — `secrets.REG_PASSWORD`.
5. **Build and Push** — `linux/amd64` only. A multi-arch build runs qemu,
which crashes the buildkit pod on this NUC (exit 255, `SandboxChanged`)
and the build then hangs for many minutes.
6. **Deploy** — installs kubectl, applies `kube/*.yaml`, creates the
image-pull secret idempotently, then `rollout restart` + `rollout status`.
The rollout restart is required: the image tag in the manifest is
`:latest`, so `kubectl apply` alone does not roll the pods.
7. **Verify the deployed app** — exercises `/healthz` and `/readyz` from
inside the pod, using the pod's own python (there is no `curl` in the
slim image).
> The deploy step does **not** delete the namespace. That would destroy the
> hand-provisioned `beer-db` and `beer-app` Secrets.
### Deploying by hand
If you need to deploy without going through CI — for example to test a
manifest change — do the same thing the workflow does:
Pushing to `master` triggers `.gitea/workflows/build_push.yml`, which runs the
test suite and then builds and pushes the image. **The workflow does not
currently deploy to the cluster** — apply the manifests yourself:
```bash
kubectl apply -f kube/beer_namespace.yaml
kubectl apply -f kube/beer-deployment.yaml
kubectl apply -f kube/beer-service.yaml
kubectl -n beer rollout restart deployment/beer-deployment
kubectl -n beer rollout status deployment/beer-deployment --timeout=180s
```
Validate the manifests before applying them. `kubectl apply` **silently
rejects** a manifest with a schema error, so a broken manifest leaves the
old Deployment in place while the job still reports success:
```bash
kubectl apply --dry-run=client -f kube/

"""Backfill the ``beer_runs`` metadata collection from the existing readings.
The ``beer_data`` collection stores a beer name on *each reading*, and that
name drifts across a run — run 4 was entered as "Necatron-Christmas Beer",
then "Nocturna the Christmas beer", then "Nocturna Christmas beer". The
``beer_runs`` collection holds one canonical name per run, which is what the
active-beers page and the analysis pages use.
This script populates that collection from the readings. It is **idempotent**
and **non-destructive**:
- It only ever inserts into ``beer_runs``. It never touches ``beer_data``.
- It never overwrites a name you have already set by hand. A run whose
metadata already carries a ``name`` is left alone unless ``--force`` is
given.
- Re-running it produces the same result.

"""Brewing advice from an LLM, generated for each recorded observation.
The advice is a *comment on the reading*, not a replacement for the
brewer's own comment. Every reading gets its own advice text, stored in
its own field, so nothing the brewer wrote is ever overwritten.
Design notes
------------
- **The LLM is never in the request path.** Recording a reading must not
block on a model that may be slow or down, so the advice is generated in
a background thread and written when it is ready. The page shows the
reading immediately and the advice appears on a later visit.
- **Failures are recorded, not raised.** If the model is unreachable the
advice field gets a short note saying so. A silent failure would look
identical to "no advice yet", which is confusing when you are waiting
for a tip that is never going to arrive.
- **The model is configurable**, with a default that is known to work on
this homelab. Several models on the Ollama instance have been retired
and fail at call time while still appearing in the model list, so the
default is verified rather than assumed.

You are an experienced home brewer giving practical advice to a single \
brewer about their own beer. You know brewing science: specific gravity, \
attenuation, yeast health, temperature, timing, and what a stalled or \
struck-out fermentation looks like.
You will be given one brew's readings so far: its name, the original \
gravity, each reading's date and specific gravity, and any comment the \
brewer wrote.
Give the brewer useful, specific, practical advice about THIS reading and \
this brew. Consider things like:
- Is the fermentation progressing at a normal rate for the style and \
temperature?
- Has it stalled, and if so what should they do about it?
- Is the yeast likely stressed, unhealthy, or done?
- Is the gravity drop plausible for the original gravity?
- Should they rack, add more hops, raise the temperature, or wait?
Rules:
- Your reply must have this exact shape:
ADVICE:
<the advice itself, two to five sentences of plain prose>
The line "ADVICE:" comes FIRST, on its own line, with nothing before
it. Do not explain your reasoning and do not show your working.
- Advise about the reading that is marked as the one to advise on. It
may not be the most recent one - the brewer may be correcting an older
reading - and the advice must be about the reading they asked about.
- If everything looks normal, say so briefly and say what to expect next.
- If something looks wrong, say what it is and what to do about it.
- Be specific to the numbers given. Do not give generic advice.
- If a reading looks like a typo or a mis-entry, say so and suggest \
checking it, but do not assume it - a slow or long fermentation can be \
genuine.
- Never say a reading is impossible. Beer cannot be denser than water, so \
a gravity below 1.000 is always a mis-entry or a typo, but the rest of the \
run may still be real and worth understanding.
