test(e2e): assert the alias where it is observable, not by posting to it

The check posted a completion under the descriptive model name and asserted a reply came back. That proves nothing: a single-model llama-server ignores the request's `model` field entirely. Confirmed against the live endpoint — it answers to "voellig-erfundenes-modell-xyz" and reports "model":"chat" — so the check passed whether or not the alias existed. /v1/models is the only place the alias is observable, and it is what a client reads to populate a picker, so both names are asserted there instead.

+# paperless-data: CephFS → RBD
+
+## Why
+
+`paperless-data` is `ReadWriteMany` on `ceph-filesystem`, but **only the paperless
+Deployment mounts it**. Verified 2026-08-20:
+
+```
+$ pods mounting paperless-data
+paperless-68cb8b8744-7hjb8      <- one, and only one
+
+paperless-data     ReadWriteMany  ceph-filesystem
+paperless-media    ReadWriteMany  ceph-filesystem   <- genuinely shared (ftp-scanner)
+paperless-consume  ReadWriteMany  ceph-filesystem   <- genuinely shared (ftp-scanner)
+```
+
+Its contents are single-writer state — the 50 MB Whoosh index,
+`classification_model.pickle`, `celerybeat-schedule.db`, `log/`,
+`migration_lock`, `protonmail.pem`. 75 files. Nothing else reads or writes them.
+
+It is on CephFS by default, not by requirement.
+
+## What it costs
+
+Every access goes through the MDS. Measured with **zero CI pipelines running**:
+
+```
+paperless-data client   request_load_avg 22   (all other sessions 0-1)
+MDS over 180s           4,052 client requests  = 22.5/s
+                        2,718 journal events   = 15/s
+                            2 dir commits      <- almost none: not file writes
+```
+
+So it is cap/inode churn from repeated access, not data being written. That is
+most of the constant **7-8 GB/day** written to `cephfs-metadata`, and since that
+pool is `size: 3`, roughly **21-24 GB/day** reaches the drives.
+
+`cephfs-metadata` deliberately stays at size 3. Losing it destroys the entire
+filesystem rather than the objects on one OSD, and the 275 GiB in `cephfs-data0`
+depends on it. Cutting the writes at source is correct; cutting the replication
+is not.
+
+## Sequence
+
+Staged deliberately: the PVC lands first and empty, so merging it changes
+nothing. The copy and the repoint are separate.
+
+### Phase 1 — provision (this PR)
+
+`paperless-data-block` (RWO, `ceph-block`, 10Gi) is created and mounted by
+nothing. Inert.
+
+Verify: `kubectl -n paperless get pvc paperless-data-block` → Bound.
+
+### Phase 2 — copy
+
+The Whoosh index must come across intact. Paperless *can* rebuild it
+(`document_index reindex`), but that reprocesses every document, so copying is
+both faster and less disruptive.
+
+1. Scale paperless to 0. The source must be quiescent — `celerybeat-schedule.db`
+   and the Whoosh index are both live-written, and copying them under an active
+   writer gives a torn read.
+2. Run a one-off pod that mounts BOTH PVCs and copies:
+   ```
+   cp -a /src/. /dst/
+   ```
+   The RWO target pins the pod to one node; the RWX source will follow.
+3. Verify file count and index size match:
+   ```
+   find /src -type f | wc -l   ==   find /dst -type f | wc -l
+   du -sh /src/index           ==   du -sh /dst/index
+   ```
+
+### Phase 3 — repoint
+
+Change the Deployment's `data` volume to `claimName: paperless-data-block`,
+merge, let it roll.
+
+Verify afterwards:
+- paperless starts, search returns results (proves the Whoosh index survived)
+- `ceph tell mds.cephfs-b session ls` no longer shows a busy `paperless-data`
+  client
+- `rate(ceph_pool_wr_bytes{pool_id="3"})` drops from its 7-8 GB/day baseline
+
+**Do not delete `paperless-data` until search has been confirmed working.** It is
+the rollback, and it is `prune: disabled` so Flux will not remove it.
+
+## Expected effect
+
+~7-8 GB/day off `cephfs-metadata`, so ~21-24 GB/day off the drives once
+replication is counted. Against ~432 GB/day cluster-wide that is roughly 5% —
+worth doing, but it is a correctness fix (a single-writer volume does not belong
+on a shared filesystem) more than a large win.
+
+It also removes 22 req/sec of MDS load, which benefits the workloads that
+genuinely need CephFS — Woodpecker CI workspaces share the same MDS.

-# Public LAPI endpoint for the firewall bouncers on proxy-1/proxy-2.
-#
-# WHY PUBLIC AT ALL. The bouncers run as host processes on the proxies, and
-# the proxies have no mesh access: the netbird-proxy container runs non-root
-# (see the ip_unprivileged_port_start task in the netbird-proxy role), so it
-# has no NET_ADMIN and no /dev/net/tun, and its embedded NetBird client
-# therefore terminates the tunnel in userspace. The tunnel belongs to that
-# process, not to the host netns — 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; this reuses the path every other service already
-# takes instead of adding two peers and an ACL policy.
-#
-# NO IP ALLOWLIST, deliberately. The bouncer key is the access control.
-#
-# An allowlist was the obvious second factor and it does not work here. A
-# request originating on a proxy host does not arrive carrying that host's
-# public address: the client connects to the local proxy on 127.0.0.1, the
-# reverse-proxy puts what it saw into X-Forwarded-For, and Traefik resolves
-# that. Measured against the 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-...
-#
-# 172.18.0.3 is a Docker bridge address on the proxy side. Allowlisting the
-# published proxy addresses would have rejected the bouncer with 403;
-# allowlisting 172.18.0.0/16 would be a private range on a host we do not
-# control the addressing of, which is not a security control.
-#
-# What remains is the API key, which is the real control anyway: this endpoint
-# serves read-only decision streams to a valid bouncer key and nothing else.
-# The admin surface is cscli, in-cluster. If the source address ever becomes
-# deterministic, an ipAllowList can be added on top.
---
-# The LAPI serves HTTPS only once tls.enabled is set — there is no plaintext
-# fallback and no second port; 8080 is the TLS port. Its certificate comes
-# from the chart's own self-signed CA, so Traefik needs that CA to verify the

-# can it actually take on?
-#
-# This is a comparison tool, not a CI gate. Point it at any OpenAI-compatible
-# endpoint and model and it prints the same scored tasks, so two models can be
-# judged side by side on the work we would give them rather than on a public
-# leaderboard.
-#
-# The tasks are drawn from real workloads:
-#   A  PR review triage — the actual rubric from ci/agents/pr-review/, run over
-#      real merged PR diffs whose correct classification is known. Includes a
-#      prompt-injection case, since the triage reads attacker-controlled input
-#      and the pipeline trusts it to hold.
-#   B  Strict JSON output, five identical runs — Home Assistant intents need
-#      parseable output every time, not usually.
-#   C  German document classification — the Paperless workload.
-#   D  German summarization under a hard length constraint.
-#
-# Usage:
-#   scripts/ai-eval.sh                          # the cluster's local model
-#   scripts/ai-eval.sh -m qwen3.6-35b-a3b
-#   scripts/ai-eval.sh -e https://other/v1/chat/completions -m some-model -k KEY
-#
-# Env equivalents: AI_EVAL_ENDPOINT, AI_EVAL_MODEL, AI_EVAL_KEY.
-#
-# To compare two models on OUR llama-server, -m is not enough: a single-model
-# server ignores the request's `model` field entirely and answers to any name.
-# Change --hf-repo in kubernetes/apps/llama-server/deployment.yaml, let it roll
-# out, then re-run. -m matters for routing servers and for hosted APIs.
-#
-# Exit code is the number of failed tasks, so a run can be compared mechanically.
