claude-botandClaude Opus 5 b96260cef2 feat(crowdsec): arm the bouncer everywhere, drop the per-host override
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
proxy-2 has been enforcing since 14:21:54 without incident, so the role
default moves to nftables and the host_vars override goes away rather than
being duplicated for proxy-1. proxy-2's rendered config is unchanged by this,
so it will not restart; only proxy-1 does.

The staged rollout did its job and can be read off the deploy log:

  proxy-1: deployed in mode "dry-run"
  proxy-2: deployed in mode "nftables"

and only proxy-2 restarted, which showed up as a 1,887,882-byte startup pull
from its address alone.

The delivery path was tested in enforcing mode with a decision on 192.0.2.1
(TEST-NET-1): both hosts had the ban 3s later as a 205-byte delta, and the
revocation as a 203-byte delta 1-2s after deletion.

What is still not proven is that a packet is actually dropped, and the
measurement for that argues for finishing the rollout rather than waiting.
Requests from banned addresses reaching Traefik stopped after proxy-2 armed —
1 at 14:02, 3 at 14:07, 22 at 14:08, 1 at 14:18, none after — but 25 of those
27 arrived in a single burst beforehand, so at this volume that is consistent
with enforcement rather than evidence of it. With both hosts armed the claim
becomes falsifiable instead: no request from an address in the decision set
should reach Traefik at all, and a single one would prove otherwise.

dry-run remains available per host through inventory/host_vars, which is what
a newly added proxy should get before it enforces.

Arming the bouncer on proxy-2 (#766) merged and deployed nothing. The switch
lives in ansible/inventory/host_vars/proxy-2.renner.uno.yml, and the trigger
list covered ansible/roles/** and the play but no inventory path at all. The
change sat in git looking applied while the host kept running dry-run, and
nothing reported a problem — there was simply no pipeline run to fail.

The bouncer's LAPI key has the same shape: it lives in
group_vars/netbird_proxy/vault.yml, so a rotation would never have reached the
hosts either.

Both paths are now listed. pve_hosts.yml deliberately is not: it is the single
inventory file for the whole fleet, so listing it would redeploy the proxies
for any unrelated host edit. The cost is that a change to [netbird_proxy] group
membership needs a manual deployment run.

Merging this triggers the run itself, since .woodpecker/deploy-netbird-proxy.yml
is in its own trigger list — so the arming from #766 applies with it.

claude-botandClaude Opus 5 021fd6a4ed docs(llama-server): cite the flag semantics instead of inferring them
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
`llama-server --help` documents both halves of what #765 got wrong, and
it ships in the image:

    -np, --parallel N   number of server slots (default: -1, -1 = auto)
    -kvu, --kv-unified  use single unified KV buffer shared across all
                        sequences (default: enabled if number of slots
                        is auto)

So leaving --parallel unset did not merely pick a slot count, it enabled
a shared KV buffer that every slot could draw the full --ctx-size from.
That is why this server reported n_ctx_slot 16384 across four slots, and
the startup log said so outright: kv_unified = 'true'. Naming a slot
count switches that off and splits the context.

The value stays 65536. Only the reasoning in the comment changes, from an
inference drawn off two /props readings to the documented behaviour.

ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
#765 claimed --ctx-size was per slot and halved the slot count to pay for
doubling it. Both halves of that were wrong. With --parallel set,
llama.cpp divides --ctx-size across the slots, so 32768 over two slots
gave 16384 each -- exactly what was there before -- and the Assist
request fails with the same message it did then:

    request (18910 tokens) exceeds the available context size (16384)

The flag does behave differently without --parallel, which is where the
wrong reading came from: the four-slot server reported n_ctx_slot equal
to --ctx-size rather than a quarter of it. Adding --parallel changed
that, and the memory reading confirms it -- the pod fell from 24979 MiB
to 21601 MiB, so total KV halved rather than holding steady.

65536 across two slots is 32768 each, and puts total KV back where it was
before #765 along with the memory that came with it.

Verify rather than assume this time:

    kubectl -n ai exec deploy/llama-server -- curl -sS \
      http://127.0.0.1:8080/props | jq .default_generation_settings.n_ctx

must report 32768.

ci/woodpecker/pr/pr-review Pipeline was successful
First host goes from dry-run to enforcing. proxy-2 deliberately: it is the
dual-stack member, while proxy-1 is IPv6-only and the one where every
network-shaped problem has surfaced first — the dhcpcd/resolv.conf breakage,
and a GitHub download that could not work at all. host_vars keeps the change
to one host; proxy-1 stays on the role default.

Verified before committing: ansible-inventory resolves nftables for proxy-2
and nothing for proxy-1.

Adds netbird.renner.uno to capi_whitelists first, and that is not decoration.
The bouncer's chain sits on the INPUT hook, the proxy hosts run no other
firewall, and there is therefore no conntrack rule accepting established flows
ahead of it. A ban on the management address would drop the return traffic of
the proxies' own outbound control connection and take them off the mesh, with
no inbound attack involved at all. The same reasoning already covers the proxy
addresses, which were listed from the start.

Checked at the time of writing: none of these addresses appear in the current
decision set — searched all ~15k entries. That is the state today, not a
guarantee; they are rented addresses on a hoster whose ranges do end up on
community blocklists, which is the whole reason for listing them.

The delivery path was tested end to end beforehand with a decision on
192.0.2.1 (TEST-NET-1, so no real traffic could be affected). Both bouncers
received the ban within one poll cycle — a 206-byte delta against the usual
26 — and the revocation the same way, 203 bytes, ~5s after deletion. What that
did not test is whether a packet is actually dropped, which dry-run cannot
show. This commit is what makes that testable.

claude-botandClaude Opus 5 60a3da9447 feat(llama-server): 32k context per slot for the Assist agent
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
The Home Assistant conversation agent is configured and refuses every
request:

    API error: request (18910 tokens) exceeds the available
    context size (16384 tokens), try increasing it

18910 breaks down as ~12k for the exposed-entity overview and ~7k for
the base instructions and tool schemas, whose parameters enumerate every
exposed name, area and floor. Trimming the exposed set from 845 entities
to 666 already took the overview from 16045 tokens to 12048; the
remainder is not the sort of thing curation reaches.

--ctx-size is per slot rather than the total, which is what makes this
affordable: /props reports n_ctx_slot equal to the flag while running
four slots, where a total would have divided down to 4096. Doubling the
flag alone would double the KV cache, so the slot count halves in step
and the allocation lands where it already is -- 24979 MiB against the
32Gi limit, most of it the 19.5 GiB of weights.

Two slots matches the actual callers: one holds Home Assistant's prompt,
one holds Paperless's, and prompt caching keeps each warm. A cold prefill
of this prompt costs about two minutes, so a third caller queueing is a
better outcome than it evicting one of them.

claude-botandClaude Opus 5 6a65a5982a feat(monitoring): scrape CrowdSec and give it a dashboard
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
A dashboard first needed something to draw. Nothing scraped CrowdSec:
`up{namespace="crowdsec"}` returned zero series and Prometheus held no cs_*
metric at all, so the detection half of the ingress path was invisible —
including whether the agents were reading logs and whether any bouncer was
pulling decisions.

Both chart services already expose a `metrics` port on 6060 and the
crowdsec-ns CiliumNetworkPolicy already admits the monitoring namespace
without a port restriction. Only the ServiceMonitor was missing. One object
covers both services via matchExpressions, since they differ only in `app`.

Every panel query was written against label sets read off the live endpoints
rather than from the documentation:

  cs_active_decisions{action,origin,reason}
  cs_lapi_bouncer_requests_total{bouncer,method,route}
  cs_bucket_overflowed_total{name}
  cs_filesource_hits_total{acquis_type,datasource_type,source}
  cs_node_wl_hits_ok_total{...,reason,...}
  cs_parser_hits_ok_total / _ko_total

The bouncer panel is the one worth having: the LAPI counts requests per
bouncer, so a bouncer that stops pulling shows up as a line going to zero
rather than as nothing at all. It also makes the `<name>@<ip>` behaviour
visible — the LAPI registers a new entry per observed client address, and what
it observes is the netbird-ingress pod IP, so one logical bouncer appears
several times and gains new names as those pods roll.

The last panel is a text panel naming what the dashboard cannot show. The
bouncers' own metrics — fw_bouncer_active_decisions, dropped packets, their
view of the LAPI — sit on 127.0.0.1:60601 on public hosts with no metrics path
of any kind. So "Bouncer-Abholrate" proves a bouncer is asking, not that it
applied the answer. Better to say that on the dashboard than to let someone
read enforcement into a panel that does not measure it.

ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
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.

HA 2026.8.3 ships a native `llama_cpp` integration, so an Assist
conversation agent backed by the cluster's own model needs no custom
component — only a path from the HA pod to llama-server, which two
default-deny policies currently block in both directions. Verified from
inside the pod: the call to llama-server.ai.svc.cluster.local:8080 times
out today.

Both grants are scoped to the single pod and port, mirroring the
paperless grant next to them, so neither widens if something else is
placed in the other namespace. llama-embed is deliberately excluded: the
conversation agent uses chat completions only.

Tool calling was verified against the running model before adding this —
the Assist API requires it, and llama.cpp only exposes it for some
builds. b10731 returns finish_reason=tool_calls and parses German
commands into the right arguments without --jinja.

Die Hosts sind öffentlich und haben bisher keinerlei Metrik-Pfad; den Port ins Internet zu öffnen, nur um ein Scrape-Ziel zu bekommen, wäre der falsche Tausch.\n\n**Konsequenz:** „Bouncer-Abholrate\" oben zeigt, dass ein Bouncer *fragt* — nicht, dass er die Antwort auch angewandt hat. Solange der Modus `dry-run` ist, wendet er ohnehin nichts an.\n\nEin Scrape-Pfad für die Hosts ist eigene Arbeit und Voraussetzung dafür, dass „was wird wirklich geblockt\" beantwortbar wird."
