Both bouncers reach the LAPI and pull every 10s, and every pull gets a 400:
2a03:4000:28:f6e:...:9a29 "GET /v1/decisions/stream?..." 400 48
2a03:4000:4b:c1e:...:8f85 "GET /v1/decisions/stream?..." 400 48
The body says what it is: "Client sent an HTTP request to an HTTPS server."
Traefik was talking plaintext to a backend that serves TLS only.
serversscheme and serverstransport were on the Ingress. Under the Kubernetes
Ingress provider `traefik.ingress.kubernetes.io/service.*` are SERVICE
annotations; on an Ingress they are silently ignored. Nothing warns, and the
failure surfaces as a 400 that reads like a malformed request rather than a
scheme mismatch. They move to the chart's Service via lapi.service.annotations.
With tls.enabled the LAPI serves HTTPS on 8080 and offers no plaintext port,
so https is mandatory here rather than hardening.
Also switches the ServersTransport from rootCAsSecrets to rootCAs, which is
what Traefik has been warning about on every reconcile:
RootCAsSecrets option is deprecated, please use the RootCA option instead.
Two of my own diagnostics were wrong along the way and both were measurement
artifacts. "Traefik sees no requests" came from a Loki query whose limit was
consumed by those deprecation warnings. And the source address that justified
dropping the IPAllowList was measured on the watchdog, which curls 127.0.0.1;
the bouncer resolves the public name and arrives on the proxy's public
address, as the log lines above show.

The download moved to the controller in the previous fix and now works. The
extraction that followed it does not:
Failed to find handler for "/tmp/crowdsec-firewall-bouncer-v0.0.36.tgz".
Command "/bin/tar" detected as tar type None. GNU tar required.
The ci-ansible image ships a tar that ansible's unarchive rejects. Both host
distributions have GNU tar, and only the download ever needed to move — the
v6-only problem was reaching github.com, not opening a tarball.
So the controller now ships the archive rather than the unpacked binary, and
the host extracts it. That also keeps the artefact the checksum was verified
against intact all the way to its destination, instead of verifying an archive
and then copying something extracted from it.

First candidate to be carried through to an end-to-end measurement. The
embedding comparison on 400 real archive documents puts bge-m3 level with the
deployed Qwen3-Embedding-0.6B where it matters and ahead everywhere else:
correspondent 74.0% vs 75.0% (ceiling 82.5%, so 90% vs 91% of achievable)
document type 70.0% vs 68.2%
time 147s vs 380s for 400 documents
peak memory 1.6 GiB vs 10.6 GiB
Same 1024 dimensions, so nothing downstream changes shape.
Note the pooling type differs — bge-m3 wants CLS where the Qwen family wants
last-token. Read from the model's own 1_Pooling/config.json rather than assumed;
across the candidates measured, three different pooling types were required, and
a wrong one produces plausible but untrained vectors with no error anywhere.
The memory limit is now measured rather than estimated. It also supersedes #745,
which raised the limit for the model being replaced: the footprint is dominated
by four slots at 4096 context plus the Vulkan working set, not by the weights —
which is why several candidates were OOMKilled at limits that looked generous
against their model size.
This is not a final answer. Every candidate has to go through the end-to-end
test (scripts/paperless-eval.sh) before the embedding choice means anything,
because nothing has yet verified that the retrieval metric predicts what
Paperless actually suggests. bge-m3 is simply the one to start with.
Changing paperless-config is also what lets that test run at all: the AI
settings from #739 have never reached the running pod, which predates the
Reloader annotation from #741. This edit gives Reloader something real to react
to, rather than forcing a restart by hand or inventing a change to trigger one.

The deploy failed on proxy-1:
Request failed: <urlopen error [Errno 101] Network is unreachable>
url: https://github.com/.../crowdsec-firewall-bouncer-linux-amd64.tgz
proxy-1 is IPv6-only, and neither github.com nor
objects.githubusercontent.com publishes an AAAA record. The host cannot reach
GitHub at all, so no retry or timeout would have helped.
Two alternatives do not work either. Mirroring into gitea.renner.uno is out:
its public records are the internal LB VIP (10.2.99.86 / fd99::86), so it is
unreachable from outside the LAN. And there is no upstream container image for
this bouncer, which is expected of something that manipulates host netfilter —
crowdsecurity publishes cloudflare, fastly, custom and others, but no firewall
bouncer.
So the controller fetches and pushes instead of the host pulling. The CI runner
has v4. The checksum is still verified, now before anything reaches a host,
which is the better place for it anyway.
The repo had told me twice that proxy-1 is the v6-only member — in
unifi_nat_hairpin.tf and in the netbird-proxy role's dhcpcd comment — and I
wrote it into the PR description myself. I never asked whether a v6-only host
can reach GitHub.
Nothing was deployed before this: the play runs serial: 1, proxy-1 went first
and failed, so proxy-2 never started.

Found by the pr-review bot on #751, and it is the exact failure this design
was written to avoid.
BOUNCER_KEY_edge is consumed as an env var from a secretKeyRef, and env is
fixed at pod start. The Reloader annotation listed only crowdsec-bouncer-key,
so a rotation of the edge key would update OpenBao, sync into the Secret, and
reach the hosts through the Ansible play — while the LAPI kept the old value
in its environment and went on trusting the old key. The bouncers would then
present the new one and get 401s, at exactly the moment the rotation was
supposed to be seamless.
The comment directly above that annotation already stated the rule — "it's an
env-var secret, so a restart is required to pick up a rotated key". I added a
second env-var secret and did not extend the list.
Comma-separated, matching shelly-manager-deployment.yaml.

Completes the pair: the ExternalSecret feeds BOUNCER_KEY_edge to the LAPI, this
feeds the same value to the bouncers that authenticate against it.
A single encrypted value rather than a whole-file vault like its siblings in
group_vars/all and group_vars/edge_host. Appending to one of those means
decrypting it first, which exposes every other secret in that file to add one
line. encrypt_string keeps the blast radius at this value, and the plaintext
never reaches a file: it goes from `bao kv get -field=key` through a pipe
straight into the encryption.
Scoped to netbird_proxy rather than all, because only those hosts run a
bouncer.
Not enrolled in the quarterly rotator, unlike crowdsec-bouncer-key. Nothing on
these hosts re-reads OpenBao on a schedule, so a rotation there would leave
them 401ing against the LAPI until someone ran the playbook. Rotating this one
means updating OpenBao and re-running plays/install-netbird-proxy.yml, in that
order.
Verified with `ansible-inventory --list`: the inventory parses and the value
decrypts.

Enforces the decisions the in-cluster CrowdSec already detects, at the point
where public traffic actually enters. These hosts terminate TLS for every
*.renner.uno name, so a drop here never reaches the mesh, the relay or the
cluster. Detection stays where it is: the reverse-proxy produces no parseable
access log and has no collection, while Traefik has a working one, and every
scenario in use needs HTTP detail that does not exist at this layer.
Deployed in dry-run. It pulls decisions and logs what it would block without
creating a single nftables rule. The first bouncer to arm anywhere enforces
~24k CAPI decisions at once on the only external entry path, so the
false-positive window has to come before the enforcement rather than after it.
Arming is flipping crowdsec_bouncer_mode per host.
The static release tarball, not a package. The AUR package
crowdsec-firewall-bouncer-nftables depends on `crowdsec` and would pull the
whole Security Engine onto hosts that need only the bouncer; the group is
mixed (proxy-1 Arch, VPS-1 Debian); and the AUR would be a pattern this repo
does not otherwise have. The tarball is the same artefact the AUR package
downloads, pinned by version and sha256, and only the binary is unpacked —
the install/upgrade/uninstall scripts beside it manage systemd and config
themselves, which would leave two owners for the same files.
retry_initial_connect is set, and it is not cosmetic. Without it the process
exits when the LAPI is unreachable at startup, and since a clean shutdown
deletes the nftables tables, the systemd restart loop would leave the host
with no blocklist at all until the first successful connect. The flag exists
in the code but not in the shipped example config.
nftables_hooks covers input and forward. input is the traffic this exists for,
because the reverse-proxy is host-networked and owns :443. forward covers the
bridge-networked http-redirect sidecar, whose packets never traverse INPUT —
the same Docker bridge that showed up as 172.18.0.3 in the Traefik access log.
Prometheus is enabled but bound to loopback. These hosts are public and have
no metrics collection path today; opening :60601 to the internet to gain a
scrape target is the wrong trade.
No CA file: Traefik serves Let's Encrypt for crowdsec.renner.uno, and
ca_cert_path is added to the system pool rather than replacing it.
Rollback is `systemctl stop` — a clean stop deletes both tables by itself.

The allowlist carried the published proxy addresses on the assumption that a
request from a proxy host arrives carrying that host's public address. It does
not.
The client connects to the local proxy on 127.0.0.1, the reverse-proxy writes
what it saw into X-Forwarded-For, and Traefik resolves that into ClientHost.
Measured against netbird-proxy-watchdog, which makes exactly this kind of
request every round:
172.18.0.3 - - [02/Sep/2026:10:12:01] "GET /" 200 websecure-immich-...
172.18.0.3 - - [02/Sep/2026:10:12:01] "GET /" 200 websecure-home-...
Two probes one second apart, one per watchdog target. 172.18.0.3 is a Docker
bridge address on the proxy side.
So the allowlist would have 403ed the bouncer. Allowlisting 172.18.0.0/16
instead is not a control: it is a private range on a host whose addressing we
do not own, and it would admit anything else that happens to originate there.
The bouncer key stays as the access control, which is what it always was. The
endpoint serves read-only decision streams to a valid key; the admin surface
is cscli, in-cluster. If the source address ever becomes deterministic, an
ipAllowList can go back on top.

Groundwork for enforcing CrowdSec decisions on proxy-1/proxy-2. Inert on its
own: an Ingress nobody calls yet, a bouncer key nobody uses yet, and a
whitelist that only ever narrows what may be banned.
The proxies cannot reach the LAPI over the mesh. The netbird-proxy container
runs non-root — that is what the ip_unprivileged_port_start task in the role
is for — so it has no NET_ADMIN and no /dev/net/tun, and its embedded NetBird
client terminates the tunnel in userspace. The tunnel belongs to that process,
not to the host netns, so a second process on the same host cannot route
through it. The alternative was a host-level NetBird client plus the LAPI on a
LoadBalancer VIP: two more peers, an ACL policy and a CNP rule. This reuses
the path every other service already takes.
Exposure is narrowed twice. The IPAllowList carries the three proxy addresses,
resolving them past the netbird-ingress pod IP through X-Forwarded-For the
same way the rate-limit middleware does — without that it would compare
against the shared forwarder IP, which is the gap behind the 2026-06-27 mass
ban. Behind it, the bouncer key. The LAPI serves read-only decision streams to
a valid key; the admin surface is cscli, in-cluster.
No CNP change is needed: crowdsec-ns.yaml already admits the traefik pods, and
ingress-default-deny carries no egress section.
BOUNCER_KEY_edge is separate from BOUNCER_KEY_ingress on purpose. The latter
rotates quarterly and both its consumers are in-cluster, so ESO propagates
within 10m. The edge hosts are Ansible-managed and read OpenBao on no
schedule, so a rotation would leave them 401ing until someone runs the
playbook. This key rotates with the playbook that carries it.
capi_whitelists.yaml is the only declarative allowlist the chart offers.
`cscli allowlists` objects live in the LAPI database, which runs without
persistence here deliberately, so anything created that way is gone at the
next restart. This file is a ConfigMap mount and survives by construction.
Upstream deprecates it; it is still the only thing that works against a LAPI
with no PVC.
It lists the proxy addresses and not the home WAN address, which is not
needed: unifi_nat_hairpin.tf DNATs the public proxy addresses to the Traefik
VIP on the UDM, so LAN clients reach the cluster directly with a LAN source
and never traverse the proxies.

The embedding model was picked from a recommendation and never compared. MTEB's
German retrieval results put the deployed Qwen3-Embedding-0.6B well down the
field, so a dozen candidates are being measured against the real archive with
scripts/embed-eval-real.sh — and they will not fit in 40Gi alongside the two
deployed models.
Growing the shared cache rather than using a scratch volume is deliberate: on a
slow connection the download is the long pole, and a shared cache lets the large
candidates pull in the background while the small ones are already being
measured. It also means nothing is fetched twice across runs, and a candidate
that wins is already local when it is promoted.
120Gi against 309 GiB currently free in cephfs-data0. CephFS has
allowVolumeExpansion, so this grows online without disturbing the running pods.

Immich's in-app migration to VectorChord is complete: both vector indexes,
face_index and clip_index, run on the vchordrq access method, and nothing uses
pgvecto.rs. The manifest still described a migration window.
`DROP EXTENSION vectors` was run against the immich database before this. It
was safe to do without CASCADE — nothing outside the extension depended on it,
which a rolled-back `BEGIN; DROP EXTENSION vectors; ROLLBACK;` confirmed
first. The embedding columns are `public.vector(512)`, which belongs to
pgvector, not to pgvecto.rs's type in the `vectors` schema. Afterwards both
vchordrq indexes are intact at 96 MB and 79 MB and the cluster stays healthy.
With the extension gone, vectors.so has nothing to serve and preloading it
only recreates pg_vectors in PGDATA. pgvector needs no preloading, so vchord.so
is the whole list.
instances goes back to 2. The blocker was never the extension as such — it was
that pg_basebackup's tar format cannot represent the long
pg_vectors/indexes/<uuid> paths pgvecto.rs creates, so a replica could not
join. That directory is now empty, 20 KiB in total, so the constraint is gone.
The image keeps its `:16-migration` tag. That is the upstream build's own name
for a multi-extension image, not a statement about this cluster, and it still
provides the two extensions in use. Moving to a different image is a separate
change with its own risk.

Both documents described work as outstanding that the cluster shows finished.
A record that says "REMAINING" long after the fact is worse than no record:
it is read as current state, and the next person plans around it.
## Home Assistant recorder
Phase 2c is done, and done correctly. Against the live database:
statistics 11,092,586 2024-03-13 20:00 -> current
statistics_short_term 1,883,709 rolling ~7 days
statistics_meta 1,480
The 2024-03-13 origin is the part that matters. It is unchanged from the
10,793,712-row count recorded on 2026-08-19, so the history was copied across
engines rather than started from zero — the exact failure the document was
written to prevent. `states` carries current rows, so db_url points at
Postgres.
The three "INERT"/"PHASE 1" comments went with it. All three described a
cluster that nothing consumed; it is now the recorder's live database, and the
render-db-url init container is load-bearing rather than inert — HA will not
start without the secret it renders.
## Bare-metal conversion
`talosctl get systeminformation` reports Minisforum MS-01 hardware with
distinct chassis serials for all three nodes and no hypervisor, so saturn and
neptune are not outstanding. Node creationTimestamp is not evidence either way:
k8s-3 still carries its 2026-05-09 object and is on metal regardless.
The runbook stays as the procedure for a rebuild.
