+The Actions **runner** is deliberately *not* part of this stack: a
+Swarm-scheduled runner cannot redeploy the Swarm that schedules it, so CI would
+be unavailable exactly when the cluster is what needs repairing. An earlier

+Runners live in two places, and only one of them counts:

+- **`runner-vps2/`** — the always-on runner, a plain `restart: always` container
+  on vps2. This is the one CI depends on.
+- **`register-lan-runner.sh`** — the desktop's systemd runner. Extra capacity.
+  **Nothing may assume it is up.** It was the only registered runner in the

+
+**Web UI and OAuth: done.** `dev.jinemi.com` is Forgejo's `ROOT_URL`
+(`FORGEJO_DOMAIN` in `docker-stack.yml`), so it is the name Forgejo generates in
+clone URLs, the Google OAuth callback, webhook payload URLs and mail links.
+
+**Registry: deliberately not done.** Renaming the registry host is a separate
+migration from renaming the web UI, and the two need not happen together.
+
+`caddy-git.conf` lists both names on a *single* site block. That is deliberate,
+not cosmetic: the `/v2/*` mesh-only matcher is per-block, so a second block for
+either name would re-expose the registry API publicly and undo hazard #15.
+Whatever else changes, keep the two names in one block.
+
+**`git.thermograph.org` must stay served.** It is not a courtesy redirect for

+
+- images are named by registry host, and the `git.thermograph.org/` prefix is
+  baked into the runner labels (`register-lan-runner.sh`,

+  Caddy's `/v2/*` matcher see a mesh source IP instead of returning 403;
+- registered runners hold the instance URL they registered with
+  (`https://git.thermograph.org`); they keep working while that name resolves.

+**This paragraph used to say a runner must never go on vps2. That was reversed
+deliberately on 2026-08-01, and the reasoning is worth keeping rather than
+quietly deleting.**
+
+The original objection stands on its merits: `container.docker_host: automount`
+gives job containers the *host's* Docker socket, so a runner on vps2 means any
+CI job has root-equivalent access to both the prod and beta stacks running
+there. An earlier revision of this stack ran the runner as a Swarm-hosted
+container on the Forgejo node and was reverted for the same class of reason.
+
+What changed is that the alternative turned out to be worse. The desktop was
+the estate's **only** registered runner, and when it went offline on
+2026-07-31 nothing merged, nothing deployed, and the nightly backup did not
+fire for 21 hours — on a repo where every branch is protected and every change
+is a PR, a single absent runner freezes the whole estate. Availability of CI
+is not a convenience here; it is what the backup and the deploy path both
+hang off.
+
+So the runner on vps2 (`runner-vps2/`) is a considered trade, not an
+oversight, and it is bounded rather than assumed benign:
+
+- `capacity: 1` — one job at a time, so a CI burst cannot contend with
+  `thermograph_web` for the box's six cores.
+- `--cpus=2 --memory=4g` on job containers, set in `container.options`. Job
+  containers are siblings of the runner rather than children, so the runner's
+  own compose limits do not reach them; that option is the only lever that
+  does.
+- `valid_volumes: []` — a job cannot bind-mount a host path, which is the
+  difference between "a job can read `/etc/thermograph.env`" and "a job
+  cannot", on the box where that file is prod's.
+- The compose project joins no `thermograph` network.
+
+Be honest about what that buys: it is defence against **accident**, not
+against a hostile workflow author. Forgejo's own database on vps1 already
+stores `VPS2_SSH_KEY`, which is root on vps2, so the material was already
+reachable — what changed is that it is now reachable by a *job* rather than
+only at rest. On a two-person estate where both people can already SSH to that
+box as root, that is the honest boundary.
+
+**If you are adding capacity rather than redundancy, raise `capacity` or add a
+runner on a box that hosts nothing.** The vps2 runner exists so that CI has a
+second home, not because prod is a good place to run CI.

+# The always-on Actions runner (vps2)
+
+The runner CI actually depends on. The desktop runner
+(`../register-lan-runner.sh`) stays registered as extra capacity, but nothing in
+the estate may assume it is up.
+
+Labels: `docker` only. `thermograph-lan` is deliberately **not** registered here
+— it was the host-native LAN-deploy label, dev moved to vps1 and is deployed
+over SSH like beta and prod, and no workflow requests it any more.
+
+## Why this exists
+
+On 2026-07-31 16:31Z the desktop — then the estate's **only** registered runner
+— went offline. For the next 21 hours nothing merged (every protected branch
+requires a check that only a runner can produce), nothing deployed, and the
+03:00Z `ops-cron` did not run. Forgejo held that scheduled run in `waiting`
+rather than dropping it, so all three jobs completed on reconnect and no backup
+was actually lost. A longer outage would not have been so kind.
+
+`docker-stack.yml` and this directory's parent README both described an
+"always-on Swarm-hosted runner" during that entire window. There wasn't one; an
+early revision had it as a Docker-in-Docker sidecar and it was removed. That is
+why the single point of failure went unnoticed for weeks, and it is the reason
+the root `CLAUDE.md` treats a stale doc as a correctness bug rather than a
+documentation one.
+
+## Prerequisites
+
+- vps2's docker daemon is logged in to `git.thermograph.org` (it is —
+  `/root/.docker/config.json`), so the daemon can pull the job image.
+- `git.thermograph.org` resolves to the **mesh** address from vps2 for registry
+  traffic. Job containers get this via `--add-host` in `config.yaml`; the host
+  daemon already has it.
+- The job image exists: `git.thermograph.org/jinemi/thermograph/ci-runner:v2`.
+  Built from `../ci-runner/Dockerfile`; see that file for when to rebuild.
+
+## Where it is deployed, and why not from the checkout
+
+**`/opt/forgejo-runner/` on vps2**, holding a copy of `docker-compose.yml` and
+`config.yaml` from this directory, plus a `data/` the runner owns.
+
+Deliberately *not* run in place from `/opt/thermograph/…/runner-vps2/`. That
+checkout is `git reset --hard`'d on every prod deploy; untracked files do
+survive that (it is the same property `deploy/.image-tags.env` relies on), but a
+single `git clean -fdx` during troubleshooting would delete `data/.runner` and
+de-register the runner. Putting the thing that repairs the estate inside the
+tree the estate rewrites is the same mistake as scheduling it on the Swarm it
+deploys.
+
+So this directory is the source of truth; vps2 gets a copy:
+
+```bash
+install -d -m 0755 /opt/forgejo-runner
+cp /opt/thermograph/infra/deploy/forgejo/runner-vps2/docker-compose.yml \
+   /opt/thermograph/infra/deploy/forgejo/runner-vps2/config.yaml \
+   /opt/forgejo-runner/
+```
+
+Re-copy after changing either file here, then `docker compose up -d`. There is
+no automation for that step and there should not be: a workflow that redeploys
+the runner runs *on* the runner.
+
+## One-time registration
+
+The registration token is short-lived and single-purpose. Fetch it from the
+Forgejo UI (**Site Administration → Actions → Runners → Create new Runner**) or
+the API, and keep it out of shell history — it is a credential, however
+briefly.
+
+```bash
+cd /opt/forgejo-runner
+mkdir -p data
+cp config.yaml data/config.yaml
+
+read -rs REG_TOKEN && export REG_TOKEN     # paste; not echoed, not in history
+
+docker run --rm -it \
+  -v "$PWD/data:/data" -w /data --user root \
+  code.forgejo.org/forgejo/runner:6.3.1 \
+  forgejo-runner register --no-interactive \
+    --instance https://git.thermograph.org \
+    --token "$REG_TOKEN" \
+    --name thermograph-vps2 \
+    --labels 'docker:docker://git.thermograph.org/jinemi/thermograph/ci-runner:v2'
+
+unset REG_TOKEN
+```
+
+That writes `data/.runner`, which holds the **long-lived** runner token. It is
+`0600` and must stay out of git — `data/` is gitignored for exactly this reason.
+Re-running `register` with a fresh registration token replaces it; the old
+registration then shows offline in the UI and should be deleted there.
+
+## Run it
+
+```bash
+docker compose up -d
+docker compose logs -f --tail=50 runner     # expect "runner: ... successfully activated"
+```
+
+Confirm Forgejo agrees, rather than trusting the log:
+
+```bash
+# on vps1, where Forgejo's database lives
+fdb=$(docker ps -qf name=forgejo_db | head -1)
+docker exec "$fdb" sh -c 'psql -U $POSTGRES_USER -d $POSTGRES_DB -c \
+  "select name, to_timestamp(last_online) as last_online, agent_labels from action_runner order by id;"'
+```
+
+Two rows, both recent. `last_online` is the only honest liveness signal — a
+runner process that is up but cannot reach Forgejo looks healthy locally and is
+useless.
+
+## Upgrading
+
+Pin changes go in `docker-compose.yml` (`image:`) and are applied with
+`docker compose up -d`. The runner token survives an image change; it lives in
+`data/.runner`, not in the image.
+
+Changing the **job** image (the `docker://…ci-runner:vN` label) is a
+re-registration or a hand-edit of `data/.runner`'s `labels` array — the same
+caveat `../ci-runner/Dockerfile` records for the desktop runner. Keep the two
+runners on the same job image or a workflow's behaviour starts depending on
+which runner happened to pick it up.
+
+## Troubleshooting
+
+**Jobs queue forever with both runners online.** The workflow asked for a label
+nobody registered. `runs-on: docker` is the only label this estate uses.
+
+**`docker pull` fails inside a job, works on the host.** The `--add-host` line
+in `config.yaml` is missing or wrong. vps1's Caddy serves `/v2/*` to the mesh
+only, and the job container has no other way to learn the mesh address.
+
+**Jobs fail with permission denied on the socket.** `user: root` was dropped

+# ============================================================================
+# WHY A SECOND RUNNER EXISTS AT ALL
+# ============================================================================
+# Until 2026-08-01 the estate had exactly one registered runner, on the desktop.
+# It went offline at 2026-07-31 16:31Z and everything stopped for 21 hours: no
+# merge could satisfy a required check, no deploy could run, and the 03:00Z
+# ops-cron -- THE backup for both application databases and for Forgejo -- did
+# not fire. Forgejo queued that run rather than dropping it, so it completed on
+# reconnect, but a longer outage would have meant real backup gaps.
+#
+# So this runner is not extra capacity. It is the one that has to be up.
+#
+# ============================================================================
+# WHY A PLAIN CONTAINER AND NOT A SWARM SERVICE
+# ============================================================================
+# Same argument as infra/openbao/config/openbao.hcl makes for OpenBao: the thing
+# that repairs the estate must not depend on the estate. A Swarm-scheduled
+# runner cannot redeploy the Swarm it is scheduled by, and if the cluster is the
+# thing that is broken, CI is gone exactly when it is needed. `restart: always`
+# on the local daemon has one dependency: the local daemon.
+#
+# An earlier revision of deploy/forgejo/docker-stack.yml did run a runner as a
+# Swarm-scheduled Docker-in-Docker sidecar. It was removed, and the docs kept
+# claiming an "always-on Swarm-hosted runner" for weeks afterwards -- which is
+# how the single point of failure went unnoticed.
+#
+# ============================================================================
+# WHAT MOUNTING THE DOCKER SOCKET ON THE PROD HOST MEANS
+# ============================================================================
+# Be plain about it: /var/run/docker.sock is root-equivalent on vps2, and vps2
+# runs prod. A workflow that can start a container can mount / and read
+# /etc/thermograph.env. This runner does not create that exposure from nothing
+# -- Forgejo's own database already stores VPS2_SSH_KEY, which is root on this
+# box -- but it does move the exposure from "a secret at rest" to "a secret a
+# job can reach", and that is a real difference.
+#
+# What bounds it, in order of how much each is worth:
+#   1. Only this repo's workflows run here, and only the owner can push to it.
+#   2. config.yaml sets valid_volumes: [] -- jobs cannot bind-mount host paths.
+#   3. capacity: 1 and --cpus/--memory keep a job from contending with prod.
+#   4. This compose project joins no thermograph network, so a job container
+#      reaches prod's services no more easily than any other host process.
+#
+# It is defence against accident, not against a hostile workflow author. On a
+# two-person estate where both people can already SSH to this box as root, that
+# is the honest boundary.

+Order: **dev → beta → prod**, with `verify-parity.sh` green throughout. The gate before
+prod is **7 consecutive green parity runs on all three environments**. That runs
+nightly from the `secrets-parity` job in `ops-cron.yml` over SSH, which gives
+continuous evidence without granting CI any vault access — the host renders, CI only
+asks it to. Forgejo's run history for that job is the record; a night the job was
+skipped, or the runner was down, does not count as green.
+
+Measured 2026-08-01, immediately after the verifier was fixed:
+
+| env | keys | result |
+|---|---|---|
+| dev | 12 | **PASS** — byte-identical |
+| beta | 24 | FAIL — 3 values differ |
+| prod | 32 | FAIL — 3 values differ |
+
+Identical three keys on both: `THERMOGRAPH_S3_SECRET_KEY`,
+`THERMOGRAPH_LAKE_S3_SECRET_KEY`, `THERMOGRAPH_VAPID_CONTACT`. All three live in
+`common.yaml`, which was seeded on 2026-07-31 at 02:30Z — *before* the Contabo
+rotation landed. dev passes because dev never layers `common`. One
+`seed-from-sops.sh --env common` fixes beta and prod together; the 7-day clock starts
+after that, not before.
 
 `TG_SECRETS_BACKEND=sops` remains a working two-way door for the whole period. Keep the
 SOPS path for a full release cycle after prod flips — it is the best mitigation
