claude-botandClaude Opus 5 33d92e133c fix(audit): track the heating-can image pins, not the deleted Ansible vars
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/push/build-ci-images Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
#476 merged first, which removed edge_open3e_pkg, edge_e3oncan_repo and
edge_e3oncan_version in favour of the image. The audit entry added here still
told the agent to read those, so it would have gone looking for variables
that no longer exist and reported nothing -- the same silent non-auditing the
entry was written to prevent.

Repointed at where the pins actually live now: OPEN3E_REF and E3ONCAN_REF as
ARGs in ci/images/heating-can/Containerfile. The awkward specifics carry over
unchanged, since they are properties of the upstreams rather than of how we
package them: open3e publishes no tags so the comparison must be against
commits, and E3onCAN's pin is an untagged commit later than its newest tag.

Added a note the previous version could not have made: heating_can_image is
:latest, so the node follows whatever CI last built. The Containerfile ARGs
are what actually fix the versions, and bumping one is what requires a
rebuild -- otherwise a reader could reasonably conclude the tag is the pin.

The pin commit itself is now a no-op against master and survives only as the
audit registration; its conflict on heating-can/defaults resolved in favour of
the image.

claude-botandClaude Opus 5 150a83ee38 fix(edge): make the capability-group invariant structural, and unstale a note
Both from review on #475.

The rule "a host in a capability group must also be in [edge_host]" was
enforced by a comment, in a file that already uses :children a few lines
below for ntp_cluster. The three capability groups are now children of
edge_host, so the relation is structural: a host added only to [heating_can]
still resolves group_vars/edge_host, where the local MQTT contract lives, and
cannot silently come up without edge_mqtt_host and friends.

That matters more than it looks. The MQTT contract only moved to group_vars
in this PR because splitting the plays exposed that the roles could not
render without each other's defaults -- so an edge host outside [edge_host]
would hit exactly the failure that change was made to fix.

Verified all four groups still resolve to edge-1, and the redundant
ansible_user on the capability entries is dropped: it is inherited from the
[edge_host] declaration rather than repeated three times.

Also unstaled a Day-2 note that still read "the pip task tracks the git
default branch (pin edge_open3e_pkg to a tag if that ever bites)". Both
services are pinned to commits now, deliberately, and pinning to a tag is not
available for open3e -- it publishes none. Replaced with the actual workflow:
the weekly update-audit reports drift, bump the pin and re-run.

claude-botandClaude Opus 5 dd6553ab07 fix(heating-can): pin open3e, and register both CAN services with the audit
open3e was installed from an unpinned git URL, so the heating bridge
silently tracked upstream main: whatever HEAD happened to be on the day a
converge ran was what ended up driving the heat pump. Now pinned to
6553c104, which was simultaneously upstream HEAD and the copy already
installed on edge-1, so the pin froze the running state and changed nothing.

A commit rather than a tag because open3e publishes none -- its tags API
returns an empty array. The package self-reports 0.7.5 at that commit, which
is useful context but is not a tag.

Honest about what this does NOT fix: pip still re-clones and rebuilds a VCS
requirement even when the SHA is pinned, because it cannot compare an
installed VCS dist against a requested URL without fetching it first.
Verified directly on the host:

  pip install --dry-run "git+...@6553c104"
    -> Cloning ... Resolved ... to commit 6553c104
       Installing build dependencies: started

So the task still reports changed and still restarts open3e on every
converge. Pinning buys deliberate versioning, not idempotence.

Pinning without an update path only converts churn into silent rot, so both
services are now registered with the weekly update-audit -- which had been
auditing neither, despite E3onCAN having been pinned since July. The audit
prompt warns that anything not listed is silently not audited, and these two
were exactly that.

The new scope entry records the awkward specifics so the agent does not
report normal states as problems: open3e has no tags at all, so it must
compare commits against the default branch; E3onCAN does tag, but sparsely,
and its pin sits between the newest tag and HEAD.

Also corrected while there: edge_e3oncan_version was commented "# V0.5.2",
which does not exist upstream. The repo's only tag is v0.5.1 (6f43b3fb), and
461dcbdf is a later untagged commit from 2026-06-21, "Fixed: MQTT client ID
collision caused stale retained values; added publish error logging".

claude-botandClaude Opus 5 0b845e7c76 refactor(edge): split the plays by capability, not just the roles
Splitting edge-host into single-concern roles left the coupling one layer
up: install-edge-host.yml was still one play applying all eleven roles to
one group. A host in [edge_host] got the Z-Wave gateway and the CAN services
whether or not it had the hardware -- the monolith again, in the play.

Inventory groups now state which hardware a host physically has, and each
playbook targets the group for its own concern:

  [edge_host]       install-edge-host.yml       base: flash-wear, log
                                                shipper, MQTT bridge, VLAN,
                                                docker
  [heating_can]     install-heating-can.yml     Innomaker USB2CAN
  [zwave_gateway]   install-zwave-gateway.yml   Nabu Casa ZWA-2
  [power_meter]     install-power-meter.yml     FTDI meter head

No flags and no `when:` on the roles. Moving a stick to another box is a
one-line inventory change, which is what it should be. A host with nothing
attached is simply absent from the capability groups -- which is what lets a
second thin client join as an NTP peer without being handed peripherals it
does not have.

The split exposed a circular dependency the single play had been hiding: the
local MQTT contract was scattered across two roles' defaults, in both
directions. mqtt-bridge's config needs edge_open3e_mqtt_user, because the
bridge authenticates to the cluster broker AS that user; heating-can and
power-meter-sml need edge_mqtt_host, because that is where they publish.
Neither role could render without the other's defaults, and it only ever
worked because one play loaded every role at once.

Those four values are the interface between the broker and its clients, not
the property of either side, so they move to group_vars/edge_host -- where
the matching secrets (edge_open3e_mqtt_password, edge_sml2mqtt_mqtt_password)
already lived. Removed from the role defaults so there is one source of
truth. Each role keeps what is genuinely its own: mqtt-bridge the cluster
endpoint and CA path, heating-can the datapoints and poll interval.

Also dropped: the legacy shared-compose teardown pre_tasks. That migration
completed on the 2026-08-08 apply (verified: /opt/edge-host/docker-compose.yml
is gone), and carrying migration cruft in a base play would be the same
mixing this commit is undoing.

Verified by --check --diff against the live host, all four plays:

  install-edge-host      ok=33 changed=0 failed=0
  install-zwave-gateway  ok=8  changed=0 failed=0
  install-power-meter    ok=4  changed=0 failed=0
  install-heating-can    ok=18 changed=4 failed=0

Three of four are fully idempotent. heating-can's four are the known open3e
pip churn plus the E3onCAN venv, which reports changed only under check mode
(it was ok in the real apply) -- and their two restart handlers.

ci/woodpecker/push/build-ci-images Pipeline was successful

Review on #476 found a real regression plus three things worth fixing before
this reaches edge-1.

Blocking: edge_open3e_devices.vx3.dpList still pointed at the old host path
/opt/edge-host/open3e/vx3plus.py. The compose file mounts that overlay at
/config/vx3plus.py and nothing mounts anything under /opt/edge-host inside
the container, so open3e would have looked for it at a path that does not
exist -- silently falling back to the stock vx3 datapoint list and dropping
the battery-module DIDs (vx3.1577-1582 and friends) the overlay exists to
add. Now /config/vx3plus.py.

Worth noting the build-time self-test could not have caught this: it proves
the binaries execute, not that devices.json resolves against the mounted
files at runtime.

Writable working directory. WORKDIR was /opt, which the COPY layers create
root-owned, while the process runs as open3e. udsoncan writes its log file
into the CWD -- the native install gave open3e's directory `owner: open3e`
for exactly that reason, and I dropped that when containerising. Now a
dedicated /var/lib/open3e, owned by the service user.

Secret mode. MQTT_PASSWORD was inline in docker-compose.yml, which is
rendered 0644. The env file this replaced was 0600, and the sibling roles on
this host keep secrets in a 0600 file beside a world-readable compose file.
Restored: credentials move to heating-can.env at 0600, referenced via
env_file.

edge_e3oncan_mqtt_format had become dead -- both services were fed
MQTT_FORMAT from edge_open3e_mqtt_format. The two default to the same string
so behaviour was unchanged, but overriding it did nothing. Wired through as
E3ONCAN_MQTT_FORMAT, which supervisord passes to e3oncan only.

Also from review: dropped the registered-but-unread heating_can_native_stopped,
and the migration now removes the emptied {{ edge_base_dir }}/open3e and
/e3oncan directories rather than leaving them behind.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/push/build-ci-images Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The smoke-test step I added errored the whole pipeline before any step ran.
It used the freshly built image as its own step image, but the Gitea registry
is private: the build steps authenticate kaniko for PUSH, nothing gives the
runner credentials to PULL. So the step could never have worked.

Moved into the Containerfile as a build-time RUN, which is better anyway --
it needs no registry credentials, and a broken image is never published
rather than published and then flagged.

It asserts what the previous revision got wrong: both services actually
execute, and supervisord's config carries both programs. That is exactly the
failure that shipped green -- supervisord pointed at
/opt/e3oncan/src/E3onCANcollect.py, which does not exist (the file is at the
repo root), so the image would have run open3e while e3oncan crash-looped
and the E380 meter went silently missing.

claude-botandClaude Opus 5 6fb760edae fix(heating-can): correct the e3oncan path, and smoke-test the image in CI
The image shipped a path that does not exist. supervisord ran
`python /opt/e3oncan/src/E3onCANcollect.py`, but that file is at the repo
ROOT -- there is no src/ directory. The `src` came from the old Ansible task,
which cloned into `{{ edge_base_dir }}/e3oncan/src`; that was the clone
DESTINATION, not part of the upstream layout, and I carried it into the
Containerfile without checking. Confirmed against the upstream tree at the
pinned commit: E3onCANcollect.py sits at the root alongside requirements.txt,
which is why the build succeeded while the runtime path was wrong.

So the image built green and would have started open3e and failed e3oncan on
every restart -- the E380 meter silently absent, with supervisord retrying
forever.

Nothing caught that, because nothing ran the image. Now CI does: a smoke-test
step uses the freshly built image as its own step image and asserts both
services execute and supervisord's config carries both programs.

It cannot exercise the CAN bus or the broker, neither of which exists on a
runner, so it verifies exactly what is verifiable without hardware. That is
still the difference between "built" and "works" -- and it belongs on a
throwaway runner, not on the production edge host, which is where I wrongly
went looking for this the first time.

Reverts my own reinterpretation. The instruction was to put both in one
container because they belong together; I argued against it on crash-isolation
grounds, then read the correction "two services, one image" as agreement with
my version rather than as a restatement of the original. It was not.

A container runs one PID 1. With two processes that PID 1 is a supervisor,
which is how a container handles multiple services. supervisord now runs both
readers: it restarts either on its own if it dies, reaps children and forwards
shutdown -- none of which a bare process as PID 1 can do for a sibling, which
was the actual answer to the concern I raised.

Also gone: the dispatch entrypoint and the argv in the compose file. Both were
the same mistake in different places -- the invocation living outside the
artifact. open3e's and E3onCAN's command lines are an implementation detail of
this image now; supervisord builds them from environment variables it expands
itself. Nothing outside the image knows either CLI, so an upstream flag rename
cannot break the compose file or an Ansible template.

The compose file supplies configuration and nothing else: one service, one
container, environment only. The credential env file is dropped -- the
credentials are environment already.

ci/woodpecker/push/build-ci-images Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Nothing is installed on the host any more. The image is built in CI with
both sources pinned, published to the registry, and edge-1 pulls and runs
it. That is the whole point of building it -- installation happens at build
time, once, not on every converge.

Removed from the node: both venvs, the E3onCAN checkout, and the two systemd
units. Kept and still rendered: devices.json, the vx3 datapoint overlay and
the broker credentials, now bind-mounted into the containers rather than
read from a venv working directory.

Two services from one image, as before: open3e drives the Vitocal/VX3 over
UDS, e3oncan listens passively for the E380 meter. Separate containers so
either can crash and restart without a supervisor as PID 1.

The migration stops AND masks the old units before the containers start.
Masked rather than disabled because two open3e instances issuing UDS
requests on one CAN bus is the failure mode to avoid, and a stray
`systemctl start` or leftover dependency should not be able to bring the
native one back alongside the container.

No missing-device tolerance here, unlike the zwave and meter roles: can0 is
this host's purpose. If it is absent the heating telemetry is down and the
run should say so rather than pass quietly.

heating_can_image replaces edge_open3e_pkg / edge_e3oncan_repo /
edge_e3oncan_version. The source pins move into the Containerfile, so what
is deployed here is a tag -- and `docker compose up -d` on an unchanged tag
is a genuine no-op, which is what removes the restart-per-converge that
pinning the pip URL could not.

Verification is limited and worth stating: plays/install-heating-can.yml
lives in #475 and is not on this branch, so only the master-side play
syntax-checks here. A --check run cannot exercise this at all -- command
tasks are skipped under check mode, so neither the pull nor the compose up
would run. It cannot be meaningfully verified until the image has been built
and #475 is merged.

Depends on #475 (the capability-split playbooks, and the MQTT contract
moving to group_vars). This branch is cut from master, so heating-can's
defaults will conflict there; #475 should merge first and this be rebased
onto it.

The image had no ENTRYPOINT and no CMD, with a comment claiming that was
deliberate because the commands are rendered by Ansible. That was
rationalising a defect.

An image with nothing runnable is not a self-contained artifact. The
knowledge of how to START each service leaked into Ansible, and the two were
not even symmetric: open3e installs a console script via pip, while E3onCAN
is an unpackaged script in a checkout, so the compose file would have had to
carry `python /opt/e3oncan/src/E3onCANcollect.py` -- an implementation detail
of this image's internal layout, in a file that has no business knowing it.
Move the checkout and every caller breaks.

E3onCAN now gets a wrapper on PATH, so both services are invoked the same
way and `docker run <image> e3oncan --help` works.

CMD prints what the image provides and exits 64 (EX_USAGE) rather than
silently doing nothing, so `docker run <image>` is self-describing. Which
service to run, and its arguments, stays the caller's choice -- the compose
file renders those, because the datapoint list and broker settings live
there.

Builds one image containing open3e (Vitocal heat pump, Vitocharge VX3) and
E3onCAN (E380 grid energy meter), both pinned in the Containerfile.

Why: both were pip-installed into venvs on edge-1, open3e straight from an
unpinned git URL. pip cannot compare an installed VCS dist against a
requested one without fetching it, so `pip install` re-cloned and rebuilt on
every Ansible converge -- reporting changed, firing the restart handler, and
putting a gap in heating telemetry each time. Pinning the SHA does not fix
that; verified directly on the host that pip still clones and rebuilds a
pinned VCS requirement. A tagged image does: `docker compose up -d` on an
unchanged tag is a genuine no-op.

It also gives the weekly update-audit a normal artifact instead of two
awkward special cases. open3e publishes no tags at all, and E3onCAN is
pinned to an untagged commit sitting between its newest tag and HEAD -- both
of which the audit currently has to be told about in prose.

One image, two services. They read the same physical installation over the
same bus and are versioned together, so they are one artifact; but they will
run as two containers from it, so either can crash and restart on its own
without a supervisor as PID 1.

Fixes a long-standing blind spot in passing: e3oncan.service set
PYTHONUNBUFFERED=1 and open3e.service did not, so open3e's stdout was
block-buffered and effectively never reached the journal or Loki. The image
sets it for both.

Build follows the existing kaniko pattern exactly -- path-scoped `when:` so
only this image rebuilds, date tag plus latest, pushed to the Gitea registry
alongside the ci-* images.

Deliberately artifact-only. The heating-can role still deploys venvs and
systemd units; moving it to a compose project is a separate change, once
this image exists and has been pulled and run once. Rewriting the role that
drives the heat pump against an image that has never been built would be the
wrong order.

Review on #474 caught that the previous commit put the daemon.json task in
docker-install, which is shared by ten plays: install-netbird-server,
install-netbird-proxy, install-n8n, install-authentik-ha, install-owncloud,
install-gatus, install-ical-proxy, install-grist and
install-music-assistant.

None of those hosts has an /etc/docker/daemon.json today -- the template and
the default were both new here -- so the next routine run of any of those
plays would have created one, reported changed, fired the Restart docker
handler, and bounced every container on that host. Unannounced restarts
across authentik, n8n, owncloud, grist, netbird, gatus, music-assistant and
ical-proxy, from a change about edge-host bootstrapping.

The --check verification could not have caught it: it only ever exercised
install-edge-host.yml, and the damage was in the other nine plays.

The comment I wrote there was the tell. It said "the services that use this
host run with network_mode: host" -- true of edge-1, false of most consumers
of that role. A justification that only held for the one host I was looking
at, written into a shared file.

Moved to edge-flash-wear, which is edge-host-only and already owns this
rationale: routing container stdout to the journal is flash-wear handling,
not generic docker setup. The networking aside is dropped -- in a flash-wear
role the only thing worth saying about daemon.json is why logging goes to
the journal.

docker-install is now byte-identical to master (git diff origin/master --
roles/docker-install/ is empty).

Two details the move needed: /etc/docker is created explicitly, because
edge-flash-wear runs before docker-install on a first bootstrap and the
directory will not exist yet; and the Restart docker handler fires at
end-of-play, by which time docker is installed.

Verified: ok=67 changed=25. The changed count is unchanged from before the
move, and no docker task appears in it -- daemon.json renders byte-identical
to what the old role produced, so it reports ok and the handler never fires
on edge-1.

Also from review: noted on the play that heating-can, zwave-gateway and
power-meter-sml each declare edge_base_dir in their own defaults so they
stay usable standalone, that play vars win, and that the two must be kept in
step.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Review on #474 found two blocking defects, both in exactly the place the
--check verification is blind: command and shell tasks are skipped, not
simulated, under check mode. So "verified with --check --diff" covered
everything except the two things that would actually have broken.

1. Ordering: a real run would have aborted.

   The legacy-project teardown lived in power-meter-sml, which the play runs
   last. zwave-gateway runs before it and does `docker compose up -d` for a
   container named zwave-js -- while the old shared project still owns that
   name. Docker enforces container names globally, not per project, so the
   command fails with "Conflict: container name already in use". That is not
   the missing-USB-device string the task tolerates, so the task fails and
   the play aborts before ever reaching the cleanup.

   Moved to pre_tasks, which is its correct home anyway: it is a migration
   step for both services, and putting it inside either one meant whichever
   ran first hit the conflict.

   The play now also declares edge_base_dir and edge_legacy_compose in its
   own vars rather than borrowing them from a role's defaults, since
   pre_tasks must not depend on role default resolution. And it removes the
   now-orphaned zwavejs.env left at the old shared project root.

2. Dangling handler.

   The libeatmydata task still notified "Restart edge compose services", a
   handler that was deleted with the old role. Masked today only because
   `creates:` makes the task report ok -- but the role's own comment says to
   delete that .so when the Alpine base bumps, and the next time it does,
   Ansible would fatally error with "handler not found". Now notifies
   "Restart zwave-js".

   Swept every notify in the new roles against every defined handler; that
   was the only unresolved one.

Also from review: kubernetes/bootstrap.sh referenced the deleted role.
Repointed to ansible/docs/edge-host.md.

Re-verified: ok=66 changed=25. The teardown moved from the power-meter-sml
group into pre_tasks and gained the orphaned-env removal, so the count goes
5 + 5 + 14 -> 5 pre-existing + 6 migration + 14 header repointing. Nothing
else moved.

The limit is worth stating plainly: this re-run still cannot prove the
teardown works, for the same reason it missed the bug. The first real apply
is the test.

claude-botandClaude Opus 5 2d9c3ba213 refactor(edge): split the edge-host role into one role per concern
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
edge-host was a single role doing eight unrelated jobs: flash-wear
mitigation, log shipping, VLAN networking, an MQTT bridge, a CAN interface,
the heating CAN services, a Z-Wave gateway and a power-meter reader.

That is not just untidy. It is what blocked a second thin client from
joining as an NTP peer: the host-generic work (journald to RAM, Alloy, the
VLAN sub-interface) could not be applied without also handing the box a
Z-Wave radio and a CAN bus it does not have. The role bound its services to
specific USB device paths, so a second host would have tried to start
containers for hardware that is not there.

Now:

  edge-flash-wear   journald -> RAM, noatime/lazytime, TRIM, eMMC health
  edge-log-shipper  Alloy: journal -> Loki
  edge-vlan         tagged VLAN sub-interface
  mqtt-bridge       loopback mosquitto -> cluster broker over TLS
  socketcan         can0 only
  heating-can       open3e (Vitocal/VX3) + e3oncan (E380 meter)
  zwave-gateway     zwave-js-ui, own compose project
  power-meter-sml   sml2mqtt, own compose project

The E380 reader lives with open3e rather than in its own role: it is part
of the same heating installation -- it feeds the heat pump's own energy
management -- not a separate system that happens to share a bus. can0 does
stay separate, because an interface is not the same concern as the services
consuming it.

Each role installs its own packages, so it stands alone. An edge host with
no peripherals takes the first five and none of the rest.

docker-daemon.json moves to docker-install with its own docker_log_driver
variable and Restart docker handler, since configuring the docker daemon was
never an edge-host concern. Handlers split ten ways; defaults split per
role; all sixteen templates and files moved with git mv.

Two deliberate behaviour changes on the node, both accepted:

1. Compose split. zwave-js and sml2mqtt shared a compose file, so touching
   either recreated both. They are now separate projects in their own
   directories. container_name is fixed, so the old project must release the
   names first -- a guarded one-time task downs it and removes the file.
   First apply costs a brief down/up on both. Data paths are unchanged; the
   zwave store is not migrated.

2. Header repointing. Templates and scripts carried "Managed by
   roles/edge-host" headers, which render onto the host -- they would have
   sent an operator to a role that no longer exists. Updating them changes
   file content, so it restarts the services that consume those files.

Verified by --check --diff against the live host. 24 changed items, and
every one is accounted for:

    5  pre-existing, unchanged from the baseline before this work:
       common timesyncd; open3e venv; E3onCAN venv; and the open3e /
       e3oncan restart handlers. The venv tasks install from a git URL,
       which pip cannot verify, so they report changed on every run --
       a separate defect, not introduced here.
    5  the compose split: zwave env + compose and sml compose to their
       new paths, plus the two legacy-project retirement tasks.
   14  the header repointing: journald conf, eMMC health script, alloy
       config, mosquitto bridge config, 80-can0.network, open3e overlay /
       env / unit, e3oncan unit, zwave backup script + env, sml2mqtt
       config -- and the resulting restarts of journald, alloy, mosquitto,
       open3e and e3oncan.

Nothing changed outside those three groups.

One consequence check mode cannot show: 80-can0.network.j2 changed, so the
"Reload networkd" handler fires on a real run and reconfigures can0,
briefly dropping the bus under open3e and e3oncan. It is absent from the
check-mode output only because shell handlers are skipped there. The VLAN
templates did NOT change, so the riskier reconfigure of the parent uplink
on this headless host is not triggered.

Also fixed in passing: the keepalived-ntp guard told operators to recover
with `--limit <host> --tags vlan40`, and referred to the edge-host role.
Both corrected. The role README becomes ansible/docs/edge-host.md -- it
documents the host, not any single role now.

claude-botandClaude Opus 5 07faf0ae69 fix(edge-host-iso): carry the bootstrap fixes into the ISO side too
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Review on #474 caught that the previous commit fixed the procedure in
ansible/roles/edge-host/README.md and left the same two defects in the two
places an operator actually reads them first.

That happened because my grep for the stale patterns ran with the working
directory set to ansible/, so `images/edge-host-iso/README.md` was a path
that did not exist. grep returned nothing and I read that as clean. A false
negative from a bad path, not a clean sweep.

Fixed now, verified from the repository root:

  airootfs/usr/local/bin/edge-install
    Printed the superseded two-command sequence at the console immediately
    after imaging -- the very first instructions anyone sees, telling them
    to run common.yml with -l edge_host. Now prints the single unrestricted
    run, plus the two steps that precede it (confirm the host resolves by
    name, add it to [edge_host]).

  README.md
    Described the image as being for `edge-1.srv.renner.uno`, a name that
    does not resolve, and repeated the same two-command bootstrap. Both
    replaced. This file is the link target of step 2 in the ansible-side
    README, so following the procedure end to end landed straight back on
    the defect #474 claims to close.

Also corrected while there: the ISO README called the target "the bare-metal
N100". edge-1 is a Wyse 3040 (Atom x5-Z8350), and the installer text further
down already says it "covers the Wyse 3040". Rewritten to describe the image
as not tied to one box or model, since the installer autodetects the target
disk -- which is what makes it usable for the second thin client.

Also from review: a comment on why `become: true` is set when the connection
is already root. Not taken -- ignore_unreachable, which common.yml sets. The
review's own reasoning applies: Ansible already skips an unreachable host and
continues with the others, so it adds nothing here.

claude-botandClaude Opus 5 e288ebe39d fix(edge-host): make the bootstrap self-contained and the runbook followable
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The documented base-install procedure had three defects, two of which are
standing house rules and one of which simply does not work.

1. It required a DHCP reservation.

   "Add the DHCP reservation/DNS entry for <host> on the UDM" was step 3 --
   a reservation as a documented precondition. Reservations are off the
   table here. The UDM registers DHCP leases in DNS on its own, so the
   record appears without one, and the host is identified by name
   everywhere: inventory, plays, README. Its address is never recorded.

2. It required --limit, because the plays were split wrong.

   Step 4 was:

     ansible-playbook plays/common.yml -l edge_host
     ansible-playbook plays/install-edge-host.yml

   The --limit was load-bearing, not sloppiness: common.yml is
   `hosts: all:!...`, so running it unrestricted while bootstrapping a
   single new box would reconfigure the entire fleet. The split left no
   other option. But --limit narrows the target list rather than staging
   anything, and leaves every other host outside convergence with no report
   that they were skipped.

   Fixed structurally rather than by deleting the flag: install-edge-host.yml
   now carries `certificates` and `common` itself -- the parts of common.yml
   that apply to an edge host -- so the bootstrap is one unrestricted run
   over the edge_host group. No second command, no limit.

   Not carried over: qemu-guest-agent (these are bare metal, not VMs) and
   monitoring-agent (Debian-oriented; edge hosts ship logs via edge-alloy).
   common.yml's loki/prometheus vars go with monitoring-agent and are not
   needed -- verified that the common role does not reference them.

3. It named a host that does not exist.

   The README said `edge-1.srv.renner.uno` in both the base-install steps
   and the Z-Wave cutover checklist. The host is `edge-1.iot.renner.uno`;
   the .srv name does not resolve, so anyone following the runbook hits a
   dead name at step 3.

Verified idempotent against the live host before committing:
`ansible-playbook plays/install-edge-host.yml --check --diff` over the whole
edge_host group -> ok=53 changed=5 failed=0, with all five changes inside
the edge-host role (open3e venv, E3onCAN checkout/venv), which was already
in this play. certificates and common contributed no changes at all.

Also checked the common role branches only on Debian/RedHat os_family, so
its OS-specific tasks skip cleanly on Arch.

Prompted by preparing a second Wyse 3040 as an NTP peer -- this is the
procedure that would have been followed to build it.

claude-botandClaude Opus 5 17c12fe13f refactor(prometheus): address the PVE nodes by name in scrape targets
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Follow-up to #472, which changed the inventory but left the same three IPv4
literals in the monitoring config and a runbook. Raised in review there.

prometheus.yml.j2:
  - pve job targets -> FQDNs
  - chrony job targets -> FQDNs, and restructured to one static_config per
    host so each carries its own hostname label

The chrony restructure is the substantive part. The previous form listed all
three targets together and recovered the hostname in relabel_configs by
regex-matching __address__ against each node's IP:

    - source_labels: [__address__]
      regex: '10\.2\.40\.201:.*'
      target_label: hostname
      replacement: 'jupiter'

That silently coupled the labels to the addressing. Swapping a target for a
name would have left every regex unmatched and the hostname label simply
absent, with the scrape still succeeding and nothing failing -- a
find-and-replace on the addresses alone would have broken the labels
quietly. Per-host static_configs remove the coupling entirely.

nodes.yml.j2: targets -> FQDNs. Already one entry per host with an explicit
hostname label, so nothing else to change.

claude-workstation/RUNBOOK.md: the kubeconfig command pointed --server at
https://10.2.40.201:6443. That is jupiter, a Proxmox host, not a control
plane node -- stale from when k8s ran as VMs on it. The cluster's endpoint
is https://k8s.renner.uno:6443 (kubernetes/talos/patches/cluster.yaml), and
the name is also what the API server certificate carries as a SAN, so an
address there fails TLS verification even when reachable. The documented
command was very likely broken as written.

Deliberately NOT changed: kubernetes/apps/pve/endpointslice.yaml. An
EndpointSlice takes literal addresses; hostnames are not valid in that
field, so those three are correct as they are.

Note this changes the `instance` label on the pve job from an address to a
name, since the relabel chain feeds __address__ into __param_target and on
to instance. Anything selecting on the old value needs updating.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful

jupiter, neptune and saturn were the last entries in pve_hosts.yml still
reached via ansible_host=<IPv4 literal>. Every other host here --
authentik, netbird, proxy, nas-1, grafana, edge-1 -- has always used its
FQDN, so these three were the outlier rather than the convention.

An address in an inventory is allocator state standing in for identity, and
it pins access to the legacy family: the names resolve IPv6-first, which is
the primary path on this network. DNS is authoritative for where a host is;
the inventory should say which host.

The short inventory_hostname is kept deliberately -- plays key on it
(ntp_servers[inventory_hostname] in install-ntp-ha.yml, node names in
opentofu, the prometheus targets) -- so only ansible_host changes.

No claim that this fixes the connection stalls seen while applying the NTP
work on 2026-08-07. Those were the IPS reacting to the connection pattern I
was generating (a port sweep, then rapid repeated SSH across hosts
interleaved with Ansible's own churn), not an address-family problem. This
change stands on convention and on not encoding a lease as identity.

claude-ws is left alone: its comment documents that obg.renner.uno is
split-horizon and resolves to the public proxy from home. That explains why
that particular name is unusable, not why a literal is right -- a name that
resolves to the wrong target calls for one that resolves correctly. Out of
scope here, and I do not know whether such a record exists.

chrony_allowed_networks contained only 10.2.0.0/16, so the rendered
chrony.conf permitted IPv4 clients and nothing else. IPv6 is the primary
address family here: ntp.srv.renner.uno resolves to fd40::123, so an
IPv4-only allow list refuses every client that uses the documented name.

This was live but invisible. The hosts carried `allow fd00::/8` in
chrony.conf for a long time without it ever being in this repository.
Applying the role on 2026-08-07 rendered the template over the live config
and dropped the line on all four NTP servers at once, taking internal NTP
down over IPv6 until it was added here.

Same class of untracked host state as the anycast service address, and the
same failure: config that exists only on the box survives right up until
something re-renders it. Reading the drifted file is not enough -- the rest
of it has to be diffed against what the template would produce.

The outage was not caught by the play, which reported the v6 master as
"serving ntp.srv.renner.uno" throughout. It was caught by querying the
service:

  chronyd -Q "server ntp.srv.renner.uno iburst"
    -> No suitable source for synchronisation

and after the fix:

  chronyd -Q "server ntp.srv.renner.uno iburst"
    -> System clock wrong by 0.001999 seconds (ignored)

with a control query against ptbtime1.ptb.de to confirm the method rather
than the target was sound.

fe80::/10 is included as well: a client on the same segment may source its
query from a link-local address, and without it chrony drops the request,
which presents as the server being unreachable rather than as a policy
refusal.

ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Applying #469 to edge-1 exposed two defects that only show up on real
hardware.

1. The VRRP address was unusable.

   keepalived took MASTER and assigned fd40::123, but the kernel left it:

     inet6 fd40::123/128 scope global dadfailed deprecated tentative
           proto keepalived
           valid_lft forever preferred_lft 0sec

   `-nodad` did not take effect -- no nodad flag on the address, and
   net.ipv6.conf.enp1s0/40.accept_dad = 1 -- so DAD ran and found a real
   duplicate: jupiter, saturn and neptune still held the address statically.
   edge-1 believed it was the v6 master while serving nothing.

   The flag is dropped rather than fixed. It was inherited from the previous
   design, where every NTP server carried the address at once and duplicate
   detection had to be suppressed for that to work. Under single-master VRRP
   the opposite holds: exactly one host should have it, so a duplicate is a
   genuine fault and detecting it is the point.

   What that costs is that the migration can no longer be done host by host.
   A static copy anywhere and a VRRP copy elsewhere cannot coexist, and the
   dadfailed state is sticky -- the kernel does not retry. install-ntp-ha.yml
   is therefore split in two: a first play withdraws every static assignment
   across the whole group, then the second hands the address to keepalived.
   Deliberately not serial, since it must finish everywhere before any host
   claims the address. There is a gap between the phases where nobody holds
   it, bounded by one play's run time; clients retry.

   The withdrawal tasks move to roles/keepalived-ntp/tasks/withdraw-static.yml
   for the first play to include. main.yml keeps the detect-and-assert guards,
   which still run every time and fail loudly if any static assignment
   survives.

2. keepalived warned:

     (NTP_VIP6) the first IPv6 VIP address should be link local

   RFC 5798 gives an IPv6 virtual router a link-local primary. keepalived
   carried on regardless, but the instance was sourcing VRRPv3 from something
   the protocol does not expect. fe80::123 is now the first
   virtual_ipaddress: it mirrors the service address and cannot collide with
   a NIC's EUI-64 link-local.

ntp_vip6 and ntp_vip6_linklocal move to group_vars/ntp_cluster.yml so both
plays read one definition rather than duplicating a service address.

Verified: `keepalived -t` on edge-1 (keepalived 2.4.1) parses the two-address
form clean, and the playbook passes --syntax-check.

claude-botandClaude Opus 5 a1e3b65cbf fix(ntp): verify the ifupdown side unconditionally, not only after a match
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Review on #469 found the Debian path still fails open, and was right that
my previous commit message was wrong to claim otherwise.

The whole Debian chain -- detect, withdraw, confirm, assert -- was gated on
`keepalived_ntp_static6_removed.changed`, which is only true when the
lineinfile regex matches exactly, prefix length included. The hook it
targets is hand-written and was never in version control, so any deviation
(a different mask, unusual whitespace, a second assignment elsewhere)
leaves .changed false and silently skips every following task. The static
assignment then coexists with the VRRP-managed one, which is the
double-assignment failure this PR exists to prevent -- just relocated from
edge-1 to a PVE host.

Same fail-open class as the Arch grep fixed in 5e01e2f1. The argument in
that commit message -- that the Debian path was safe because
`ip -6 addr show ... to <prefix>` matches by range -- is true of the runtime
checks but says nothing about the lineinfile text match, which is a
different mechanism and was exactly as fragile as the pre-fix Arch grep.

Fixed by checking the CONFIG FILE unconditionally, prefix-agnostic and
\b-anchored, mirroring the networkd check.

Note this is deliberately not the fix the review proposed. It suggested
running the runtime `ip -6 addr show ... to <addr>` check and its assert
unconditionally. That would break the PR: after migration the address is
legitimately present on whichever host is the elected v6 master, so an
unconditional "must be absent" assert fails on the master on every run. The
config file is the right thing to check every time precisely because
keepalived never writes there -- anything found is by definition static,
whereas the live address is expected on the master. The runtime withdrawal
stays gated on .changed, which remains correct for it.

Verified on jupiter:
  grep -rlE 'fd40::123\b' /etc/network/interfaces /etc/network/interfaces.d/
    -> /etc/network/interfaces

Sequencing holds: on the migration run the lineinfile removes the hook
first, so the grep finds nothing and the assert passes; if the regex does
not match, the grep finds it and the assert fails loudly instead of
skipping.

claude-botandClaude Opus 5 5e01e2f1b5 fix(ntp): detect a static networkd assignment at any prefix length
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The Arch guard added in the previous commit grepped for the literal
"fd40::123/128" -- the full address/prefixlen from ntp_vip6. A hand-written
[Address] using any other mask (/64, say) would not have matched, the
assert would have passed, and keepalived would have been handed an address
networkd was still assigning.

That fails open, which is the wrong direction for this particular check.
It is detect-only: there is no delete afterwards whose result gets
re-verified, so a miss is silent, and the outcome is the dual-ownership
state the guard exists to prevent.

The Debian path does not share the problem. `ip -6 addr show ... to
<prefix>` matches by range regardless of the prefix length the address was
actually assigned with, and its `ip addr del` -- which IS prefix-sensitive
-- is re-verified by a following assert, so a mismatch there fails loudly.

Now matches the bare address, anchored with \b so it cannot instead hit a
longer address sharing the prefix. Verified both directions:

  grep -rlE 'fd40::123\b' /etc/systemd/network/   on edge-1
    -> /etc/systemd/network/10-enp1s0.40.network  (still detected)
  grep -cE 'fd40::123\b' against 'Address=fd40::1234/64'
    -> 0                                          (no false positive)

claude-botandClaude Opus 5 40ef53fa67 fix(ntp): assert the static service address is really gone before handing over
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Second review round on #469 found two ways the migration could silently
leave the address outside VRRP control -- both of which would defeat the
health gating while the play reported success.

1. The one-shot migration had no verification.

   Gating the withdrawal on `keepalived_ntp_static6_removed.changed` is what
   makes it idempotent, but it also means it gets exactly one attempt and
   never retries. Combined with `failed_when: false` on the delete, a
   mismatch would pass silently: `ip addr del` matches on address AND prefix
   length, so a host whose static assignment used a different mask or
   interface than ntp_vip6 / keepalived_ntp_interface would see the delete
   no-op, keep the address permanently outside VRRP control, and still
   report success.

   The idempotency fix from the previous commit created this: making the
   task run once removed the retry that would otherwise have masked it.

   Now asserted explicitly after the delete, with a message naming the
   likely cause and the commands to inspect it.

2. edge-1 -- the host the incident actually happened on -- was not covered.

   The removal tasks are gated to Debian, so they never touch edge-1 (Arch).
   Its static [Address] block belongs to the edge-host role, and
   install-edge-host.yml is a separate play with no ordering relationship to
   this one. Nothing guaranteed it had been re-applied.

   edge_host already sets ntp_keepalived_enabled: true, so the next run of
   install-ntp-ha.yml gives edge-1 the NTP_VIP6 instance immediately. With
   the [Address] block still present it would hold fd40::123 statically AND
   run VRRP for it: keepalived would believe it had withdrawn the address
   while networkd kept it assigned, and the host would go on answering NTP
   with a clock check_ntp had already rejected. That is the failure of
   2026-08-04, on the same host.

   This is not hypothetical -- edge-1 still has the block right now:
     grep -rl fd40::123/128 /etc/systemd/network/
     -> /etc/systemd/network/10-enp1s0.40.network

   The role now detects this and fails fast, naming the play to run first,
   rather than proceeding into a split-ownership state.

Also documents why the post-deploy presence check is meaningful: presence
alone cannot distinguish a VRRP-held address from a static leftover, and
only means what it claims because the role asserts no static assignment
survives on either distro.

Not taken: narrowing serial: 1 so routine runs are not serialised through
the chrony settle pause. Real cost, but correctness of the address handover
comes first at four hosts.

claude-botandClaude Opus 5 fbf5c4dcb8 fix(ntp): make the static-address withdrawal run once, not every play
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Review on #469 caught a real defect. The withdrawal task used
ansible.builtin.command with no changed_when, so it reported changed and
fired `notify: restart keepalived` on every run where the address was
present.

That is fine exactly once. After this lands, fd40::123 is legitimately
present on whichever host is the elected v6 master, put there by keepalived
-- and an ungated delete cannot tell that apart from a static assignment,
because the address looks identical either way. So every later run of this
play (adding a host, changing a priority, plain re-convergence) would have
deleted the master's address and restarted keepalived, dropping the service
address and forcing a re-election each time. That is precisely the flapping
this change exists to prevent.

Both the check and the delete are now gated on the ifupdown hook having just
been removed, so they run once during the migration off static config and
never again. Steady-state runs leave the master's address alone.

Also from review:

  - failed_when: false on the delete. The desired end state is "address
    absent". If check_ntp fails in the window between the check and the
    delete, keepalived withdraws the address first and `ip addr del` errors
    on an address that is already gone -- the outcome the task wants, and no
    reason to abort the play for that host.

  - The play's post-deploy verification only ever checked the IPv4 VIP. The
    v6 address is the path clients actually use, so a broken v6 rollout --
    address never claimed, or -nodad not behaving as expected on a given
    kernel -- would not have surfaced in the play at all. It now gets the
    same check, and the message points at check_ntp and the health log for
    the case where no host holds it.

Not taken: the suggestion to narrow serial: 1 so it does not also serialise
chrony. With four hosts it costs nothing, and scoping it per-role would mean
splitting the play. Worth revisiting if the cluster grows.

claude-botandClaude Opus 5 112299da49 fix(ntp): remove the static service address so keepalived can own it
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
Without this the health gating is defeated on three of the four NTP
servers. fd40::123 was assigned statically on every one of them, by hand
and in two different ways, none of it in version control:

  PVE nodes  `up ip -6 addr replace fd40::123/128 dev vmbr1.40 nodad`
             in /etc/network/interfaces
  edge-1     an [Address] block in /etc/systemd/network/

A statically assigned copy does not disappear when keepalived decides the
host is unfit to serve time. Leaving it in place means the host keeps
answering NTP on an address VRRP believes it has withdrawn -- exactly the
failure this whole change exists to prevent, with the added confusion of
keepalived reporting the address as released.

The ifupdown hook is removed here. edge-1 needs nothing: the edge-host
networkd template has never carried the address, so applying that role
drops it.

The live address is deleted as well, because removing the config line alone
does not take effect until the next network reload, and a reload on a PVE
node interrupts guest connectivity including the Talos VM and its Ceph OSD.
Deleting it is safe where keepalived already holds it: the deletion
notifies a keepalived restart, and the elected master re-adds it on the way
back up. Doing it unconditionally avoids having to tell "assigned
statically" from "assigned by keepalived", which the address alone does not
reveal.

The play now runs serial: 1. Withdrawing the address and restarting
keepalived on every NTP server at once would leave the fleet with nobody
holding fd40::123 until the elections settle; serialised, the remaining
members answer throughout.

Verified against the live hosts rather than assumed:
  - all three PVE nodes carry the identical hook (jupiter:54, saturn:55,
    neptune:56), so one task covers them
  - the removal regexp matches exactly one line per host
  - `ip -6 addr show dev <if> to <addr>` prints the matching address when
    present and nothing at all when absent, so the guard condition is sound

claude-botandClaude Opus 5 01e843beef fix(ntp): apply the v6 service address to every ntp_cluster member
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The previous commit set keepalived_ntp_vip6 in group_vars/edge_host, which
would have given the v6 VRRP instance to edge-1 alone. The other NTP
servers would have rendered no NTP_VIP6 instance at all and stayed silently
outside the election -- so the address could never fail over to them, and
the health gating would have amounted to "edge-1 withdraws and nobody takes
over".

Moves it alongside ntp_vip in plays/install-ntp-ha.yml, which is already
where the service-wide address lives, and passes it to the role for every
host in ntp_cluster.

Verified that edge-1 is currently BACKUP and does not hold the IPv4 VIP: a
VRRP BACKUP receiving no advertisements promotes itself to MASTER, so the
other members are alive and one of them holds it. They are real
participants, not retired hosts.

Not verified: whether the other members also carry fd40::123 statically, as
edge-1 did. They have no DNS records -- jupiter/saturn/neptune resolve only
through the *.renner.uno wildcard to the proxy -- so there is no hostname
path to them to check. If they do carry it statically, that address must be
removed at the same time this lands, or two hosts will hold it outside VRRP
control.

claude-botandClaude Opus 5 2fbce12b0b feat(ntp): hold the IPv6 service address in keepalived, gated on clock health
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
ntp.srv.renner.uno resolves to fd40::123 (IPv6) and to the keepalived VIP
(IPv4, legacy). IPv6 is the primary family here, so the v6 address is the
path clients actually use -- and it was the one with no health gating at
all.

It was assigned statically in /etc/systemd/network/ on edge-1, so networkd
carried it unconditionally from boot. That is how the host answered NTP
queries on 2026-08-04 while its clock was ~16 days in the past: chronyd was
running, udp/123 was listening, the address was up, and nothing anywhere
was checking whether the clock was right. Fixing the keepalived health
check does not help, because keepalived was not holding that address.

This moves it into keepalived as a second VRRP instance tracking the same
check_ntp script, so the address exists only while the host is fit to serve
time.

Three details that are load-bearing rather than stylistic:

  - A separate vrrp_instance is mandatory. keepalived requires that "all
    addresses in virtual_ipaddress must be of the same family", so the v6
    address cannot join NTP_VIP.

  - No authentication block. VRRPv3 removed authentication (RFC 5798) and
    keepalived always uses version 3 for IPv6 instances.

  - track_script uses `weight 0`, overriding the script's -20. A non-zero
    weight only subtracts from priority on failure, so the last remaining
    host -- having nobody to lose the election to -- would stay MASTER and
    keep serving a clock it had already reported as wrong. Weight 0
    transitions the instance to FAULT instead, releasing the address
    unconditionally. That is the required behaviour: a host unfit to serve
    time must stop answering whether or not a replacement exists.

Semantic change, deliberate and worth stating: VRRP is a single-master
unicast VIP, not anycast. Previously every NTP server carried fd40::123 and
clients reached whichever answered neighbour discovery first. Now exactly
one host holds it. For NTP this is the better trade -- query volume makes
load spreading pointless, and on failover keepalived sends unsolicited
Neighbour Advertisements so client neighbour caches update in seconds,
where the static address had no withdrawal signal at all and clients kept
using a dead holder until their own neighbour unreachability detection
expired. True routed anycast with health withdrawal would mean announcing
the /128 via an IGP, which the gateway would have to speak.

The edge-host role is deliberately untouched: its template already has no
[Address] block, so applying it removes the hand-placed address, and
keepalived then adds it back under health control. The service address is
NTP-role configuration and now lives there.

Validated with `keepalived -t` against keepalived 2.4.1 on edge-1 using the
config as it renders for that host; parses clean apart from the pre-existing
auth_pass truncation warning on the IPv4 instance.

claude-botandClaude Opus 5 601290dcd9 fix(ntp): make the keepalived health check verify the clock, not liveness
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
The NTP health check asked "is chronyd alive", never "is this host safe to
take time from". Those came apart on 2026-08-04.

edge-1's CMOS battery is dead. After a power loss its clock came up ~16
days in the past and, with no makestep directive, chronyd never corrected
it. All three health checks passed continuously for ~18h:

  - chronyd was active
  - `chronyc tracking` responded
  - udp/123 was listening

and `local stratum 10` meant chronyd advertised itself to clients as a
valid reference the whole time. keepalived would have kept the VIP on a
host ready to serve a clock from July.

The sharpest part: check 2 ran `chronyc tracking >/dev/null 2>&1` and
discarded the output. The one command that knew the answer was executed
and its answer thrown away. During the incident that output read:

  System time     : 1376235.375000000 seconds slow of NTP time

This captures the output and adds two assertions:

  - offset above keepalived_ntp_max_offset (default 1.0s) fails, so a host
    that knows its clock is wrong drops the VIP
  - no upstream source selected in `chronyc sources` fails, because with
    `local stratum N` chronyd advertises itself as a usable reference even
    when it has never synchronised to anything -- upstream chrony docs are
    explicit that the local reference activates immediately in that case

Both predicates were validated against live output from edge-1 rather than
assumed: the offset comparison against the real incident value, and the
`chronyc sources` selected-source column against a real run.

Failing the check costs the configured weight (-20). When the WAN is down
every host fails together and loses the same weight, so relative priority
is unchanged and the VIP stays put -- the local-reference fallback still
works. What this prevents is one host with a broken clock winning.

Scope: this hardens the keepalived path, which is legacy. It does not
address the documented end state in plays/install-ntp-ha.yml, where edge-1
becomes the SOLE NTP server -- there, a failing check means no host serves
time at all, converting "serves the wrong time" into "serves no time".
That needs an architectural answer, not a better health check.

# what is plugged into it. The peripherals live in their own playbooks against
# their own inventory groups:
#
# plays/install-zwave-gateway.yml [zwave_gateway] ZWA-2 radio
# plays/install-heating-can.yml [heating_can] Innomaker USB2CAN
# plays/install-power-meter.yml [power_meter] FTDI meter head
#
# Splitting the roles without splitting the plays would have kept the coupling:
# one play applying every role to one group is the monolith again, a layer up.
# A host with no peripherals is simply absent from those groups -- no flags, no
# `when:` on the roles.
#
# Self-contained: `certificates` and `common` are the parts of plays/common.yml
# that apply to an edge host, carried here so bootstrapping one is a single
# unrestricted run over the group. Not carried over: qemu-guest-agent (bare
# metal, not VMs) and monitoring-agent (Debian-oriented; these hosts ship logs
# via edge-log-shipper).
#
# Order is dependency order: edge-flash-wear before docker, so the journal is
# volatile before containers start logging into it.

# DAD is enabled on the VRRP address (see keepalived.conf.j2), so a static copy
# on any host and a VRRP-managed copy on another cannot coexist: the kernel sees
# the duplicate and marks the newcomer `dadfailed`, leaving a master that
# believes it is serving while carrying an unusable address. Observed on edge-1
# on 2026-08-07, where keepalived reported MASTER while the address sat
# `dadfailed deprecated tentative` because three PVE nodes still held it
# statically.
#
# Doing the withdrawal per host inside the main role could not avoid that: with
# serial: 1 the first host would claim the address via VRRP while the rest were
# still static. Fleet-wide first, then claim.
#
# fd40::123 was assigned by hand on all four servers, in two different ways,
# none of it in version control:
#
# PVE nodes an `up ip -6 addr replace ... nodad` hook in
# /etc/network/interfaces
# edge-1 an [Address] block in /etc/systemd/network/, owned by the
# edge-vlan role and removed by re-applying it -- not touched
# here, since this role must not rewrite another role's file
#
# There is a service gap between this play and the next, while no host holds
# the address. It is bounded by the run time of one play and clients simply
# retry; the alternative is the dadfailed state above, which does not resolve
# on its own.

# output -- the one command that knew the answer.

# * "provably wrong" -> chronyd HAS upstream measurements and they say the

# * "no upstream yet" -> nothing reachable / not yet measured. Also fail, but

# IPv6 service address for NTP (ntp.srv.renner.uno). IPv6 is the primary
# address family here, so this instance -- not the IPv4 one above -- is the
# path that matters.
#
# A separate instance is mandatory, not stylistic: keepalived requires that
# "all addresses in virtual_ipaddress must be of the same family", so the v6
# address cannot be added to NTP_VIP.
#
# No authentication block: VRRPv3 removed authentication (RFC 5798), and
# keepalived always uses version 3 for IPv6 instances. Configuring auth here
# is rejected rather than ignored.
#
# The first address is link-local, and must be. RFC 5798 gives an IPv6 virtual
# router a link-local address as its primary, and keepalived warns
# "the first IPv6 VIP address should be link local" otherwise. It carries on,
# but the instance is then sourcing VRRPv3 from something the protocol does not
# expect.
#
# DAD is deliberately left ON (no -nodad). The flag was inherited from the
# previous design, where every NTP server carried fd40::123 simultaneously and
# duplicate detection had to be suppressed for that to work at all. Under
# single-master VRRP the opposite is true: exactly one host should hold the
# address, so a duplicate is a genuine fault and detecting it is the point.
#
# This does mean the migration cannot leave a static copy anywhere while a
# VRRP-managed one exists -- DAD sees the two and marks the newcomer
# `dadfailed`, leaving a master that believes it is serving while carrying an
# unusable address. Observed on edge-1 on 2026-08-07. install-ntp-ha.yml

# check_ntp passes, and is withdrawn as soon as it fails. On withdrawal
# keepalived sends unsolicited Neighbour Advertisements so client neighbour
# caches are updated immediately -- a statically assigned address cannot do
# this, and clients would keep sending to the dead holder until their own

roles/collections) and `opentofu/providers.tf` + `opentofu/.terraform.lock.hcl`.
Report any with a newer published version.
7. **Edge heating CAN services** — open3e (Vitocal heat pump, Vitocharge VX3)
and E3onCAN (E380 grid energy meter), shipped as one image built from
`ci/images/heating-can/Containerfile` and deployed by
`ansible/roles/heating-can`. Nothing else tracks them. They read and (for two
datapoints) write the heat pump over its CAN bus, so silent drift here
matters more than most.
Both upstream pins are `ARG`s in the Containerfile -- `OPEN3E_REF` and
`E3ONCAN_REF` -- not Ansible variables. Read them there, and note the
awkward bits so normal states are not reported as problems:
- open3e publishes **no tags at all** (its tags API returns an empty array),
so compare `OPEN3E_REF` against the default branch:
`https://api.github.com/repos/open3e/open3e/commits?per_page=1`. Report how
many commits behind and the dates. "No release found" is normal here.
- E3onCAN tags, but sparsely, and `E3ONCAN_REF` is an untagged commit later
than the newest tag. Compare against both
`https://api.github.com/repos/MyHomeMyData/E3onCAN/tags` and the default
branch, and say which the pin sits between.
The deployed image tag is `heating_can_image` in
`ansible/roles/heating-can/defaults/main.yml`. It is `:latest` today, so the
node follows whatever CI last built -- the pins above are what actually fix
the versions, and bumping them is what requires a rebuild.

# Heating system over the Viessmann E3 CAN bus: open3e (Vitocal heat pump and
# Vitocharge VX3) and E3onCAN (E380 grid energy meter).

# One image, two services. They read the same physical installation over the
# same bus and are versioned together, so they are one artifact -- but they run
# as two containers from this image so either can crash and restart on its own
# without a supervisor as PID 1.
#
# Why an image at all: both were pip-installed into venvs on the host, open3e
# straight from a git URL. pip cannot compare an installed VCS dist against a
# requested one without fetching it, so `pip install` re-cloned and rebuilt on
# every Ansible converge -- reporting changed, restarting the service, and
# putting a gap in heating telemetry each time. Pinning the SHA did not fix
# that (verified: pip still clones and rebuilds a pinned VCS requirement). A
# tagged image does: `docker compose up -d` on an unchanged tag is a genuine
# no-op.
#
# It also gives the weekly update-audit a normal artifact to track instead of
# two awkward special cases -- open3e publishes no tags at all, and E3onCAN is
# pinned to an untagged commit between releases.
