fix(llama-embed): size the batch for bge-m3's tokenizer, not Paperless's

The LLM index rebuild ran for 79 minutes and then died: input (1069 tokens) is too large to process. increase the physical batch size (current batch size: 1024) Setting the batch to Paperless's chunk size looked like an exact match and was not. Paperless counts its 1024 tokens with llama_index's tokenizer; this server measures the batch in bge-m3's, which is XLM-RoBERTa and splits German into more pieces. A chunk Paperless considered full arrived here 4.4% over the limit, and the request failed rather than truncating. 1536 absorbs a tokenizer ratio rather than a rounding error. 2048 stays out of reach: that is where the chat model hit ErrorDeviceLost on this Vulkan stack, under a 20 GB model's memory pressure that a 600 MB one may well not reproduce — but there is no reason to go looking. The index is left partial by the failed run and has to be rebuilt with `document_llmindex rebuild` once this is live. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

-# 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

+#
+# 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

+#
+# To compare two models on OUR llama-server, -m is not enough: a single-model
