fix(talos): give nodes an IPv6 InternalIP from the mgmt ULA

cilium-health reports 0/3 reachable on every node, with Node 1/2 and
Endpoints 2/2 — exactly one of the two node probes fails, including
against localhost.

The Node objects carry only InternalIP=10.2.40.x, because kubelet's
nodeIP.validSubnets lists only the IPv4 mgmt subnet. With no IPv6
InternalIP to take from the Node object, Cilium falls back to detecting
the node's IPv6 from mgmt0 and picks the SLAAC address derived from the
dynamic provider prefix. It records that in CiliumNode and probes it
until the agent restarts, so a prefix change leaves every agent probing
an address that no longer exists:

  cilium-health:  2003:d6:9718:3b02:5a47:caff:fe74:7027
  mgmt0 now:      2003:d6:9713:b202:5a47:caff:fe74:7027

The interface identifier is the same EUI-64; only the prefix moved. This
is not a one-off — the prefix was 2003:d6:9744:4802 in May and
2003:d6:9718:3b02 in August.

The GUA was never meant to be a control-plane address; that is what the
ULA is for, and BGP already peers on fd40::/64. Listing it in
validSubnets gives the Node a stable IPv6 InternalIP, which Cilium then
uses in preference to its own detection — the same path that already
makes CiliumNode's IPv4 InternalIP agree with the Node object.

Verified fd40::/64 SLAAC addresses are present on mgmt0 on all three
nodes, so no node is left without an address in a listed subnet.

The data path is unaffected either way: Endpoints probes are 2/2 and
conntrack is clean. What this fixes is the health signal, which is
permanently red today and therefore useless for spotting a real outage.

 **Migrate statistics only.** Copying all 18M `states` rows is slow, needs a long
 HA outage, and buys a table that is discarded within 7 days anyway.

-# 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.

+Terminus (self-hosted TRMNL BYOS server) plus the headless renderer that
+screenshots the Home Assistant entrance dashboard and pushes it in. One
+device: a TRMNL X at the entrance, 1872x1404, 16 greys.
+
+## Device firmware
+
+Terminus mirrors one model-agnostic binary and it is the **ESP32-C3** (OG)
+build. This panel is a TRMNL X, i.e. ESP32-S3, so that file is not the
+artefact for a manual flash here. Use
+`https://trmnl-fw.s3.us-east-2.amazonaws.com/trmnl_x/flash/FW<version>.bin`
+— a merged image at offset `0x0` — and run `esptool image-info` on
+anything before writing it.
+
+The panel runs 1.8.16, flashed over USB on 2026-09-05. It shipped on
+1.8.6, where turning on `firmware_update` froze the screen for as long as
+an update was offered (fixed upstream in 1.8.7, commit `9b7a0f7`).
+
+## Image automation
+
+Both images are enrolled (`infrastructure/image-automation/terminus.yaml`,
+`trmnl-renderer.yaml`) and track the latest `0.x`. A bad bump on either
+surfaces as a **blank or corrupted panel**, not as a failed rollout — no
+readiness probe can tell that a rendered screen became unreadable. Look at
+the panel after a bump lands; revert the tag if it is wrong.
+
+## Device endpoint
+
+`trmnl-device.renner.uno` is the device-facing name, TLS via Traefik
+(`device-ingress.yaml`). `API_URI` must carry the same scheme the device
+polls with, because Terminus bakes it into the absolute `image_url` it
+returns. The LoadBalancer in `device-service.yaml` keeps `10.2.99.89`
+without a hostname as a cleartext fallback that depends on neither
+Traefik nor certificate renewal — the captive portal accepts a bare
+address.

+# 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 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

-- `ghcr.io/usetrmnl/terminus` — publishes a usable `0.x.0` tag stream, so
-  unlike the three above this is **not** a tag-format problem. It is left
-  unenrolled because the blast radius is hardware: Terminus is pre-1.0,
-  cuts no GitHub Releases and ships no changelog, and it serves the
-  firmware and `/api/display` contract that the TRMNL X panel polls. An
-  unattended bump that changes either can leave a wall-mounted device
-  dark, with no rollback path that doesn't involve the captive portal.
-  Bumps are a reviewed, manual act: read the commit range, then edit the
-  tag in `kubernetes/apps/trmnl/terminus.yaml` (both containers).
-
-  The Valkey sidecar alongside it *is* enrolled (`valkey.yaml`) — it holds
-  only the Sidekiq queue and touches no device-facing contract.
-
-- `ghcr.io/usetrmnl/trmnl-ha-amd64` — the TRMNL screenshot renderer, for
-  the same reason and one more. It owns the dithering pipeline and the
-  webhook payload shape, so a bad bump surfaces as a *corrupted or blank
-  panel*, not as a failed rollout — there is no readiness signal that
-  catches "the image is now unreadable". Separately, upstream publishes
-  **no multi-arch manifest**: only the arch-suffixed `trmnl-ha-amd64` and
-  `trmnl-ha-aarch64` repositories exist, so an ImagePolicy here would also
-  be pinning us to one architecture in a way the tag does not make
-  obvious. Bump manually in `kubernetes/apps/trmnl/renderer.yaml`.
+Only a tag-format problem belongs on that list. The policy is to run the
+latest version and let image-automation hold us there wherever the tags
+allow it, so an image with a usable semver stream gets enrolled even when
+a bump carries risk. Where a bad bump is hard to detect, the answer is a
+note about what to check afterwards — see `apps/trmnl/README.md` for the
+panel, whose failure mode is a blank screen rather than a failed rollout
+— not an exclusion.

+#             feeds to the classifier
+#   Recall@3  it at least made the shortlist

+#   margin    cosine gap between the correct document and the best wrong one.
+#             A model that is right by 0.002 is guessing; one that is right by
+#             0.15 has actually separated them.

+# The corpus deliberately contains confusable pairs — two Allianz policies, four

+# Comparing chat models on Paperless suggestions
+
+Which local LLM is worth running behind paperless-ngx's AI suggestions, measured
+against documents a human already filed, in the `paperless-eval` namespace
+rather than against the live archive.
+
+**Applied by hand, not by Flux.** A Job is immutable, so re-running a
+configuration means deleting and recreating it, and a Flux-managed Job would
+simply come back. The namespace itself *is* managed
+(`kubernetes/apps/paperless-eval/`); only the measurement is not.
+
+## Running one
+
+Screen first, always:
+
+```sh
+./run-candidate.sh qwen3-8b 5          # ~5 min to a rejection, ~10 to a pass
+kubectl -n paperless-eval logs -f job/eval-qwen3-8b -c eval
+
+kubectl -n paperless-eval delete job eval-qwen3-8b
+./run-candidate.sh qwen3-8b            # the real measurement, 50 documents
+```
+
+Three of the first four candidates could not do the task at all, and each was
+left running for an hour before anyone looked. eval.py now stops after three
+consecutive failures from the first document, so a screening run rejects a
+hopeless candidate in about five minutes.
+
+Screening uses genuine paperless requests. That matters — `probe-toolcall.sh`
+is cheaper still and worth a first pass, but it passed two candidates that then
+failed on document one, because a synthesised request cannot reproduce the RAG
+neighbours and taxonomy candidate lists that make a real prompt what it is.
+
+Never compare numbers across sample sizes. A screen is a gate; the comparison
+happens at 50.
+
+Candidates live in `candidates.tsv`; the runner substitutes the model-specific
+values into `job-template.yaml` and refreshes the `eval.py` ConfigMap. Adding a
+candidate is a line in that file, not a copy of the manifest — the sidecar
+configuration deliberately exists once.
+
+Two run at a time: the pod anti-affinity puts one per node, and only two nodes
+have a free iGPU. A third waits.
+
+Re-running after an edit needs the old Job gone first:
+`kubectl -n paperless-eval delete job eval-<label>`.
+
+Results land on the `paperless-eval-results` PVC as `<label>.jsonl` (one row per
+document) and `<label>.summary.json`, and in the pod log.
+
+## What is being compared
+
+The candidates against each other. The scikit-learn classifier runs in every
+job as a fixed reference line — it costs 15 seconds and keeps running in
+production whatever the LLM does, so `llm_rescued` against `llm_only_wrong`
+says what *this* model adds on top of it.
+
+Do not read the classifier's own score as a quality bar. `train()` fits on every
+non-inbox document with no holdout, so the evaluation documents are in its
+training set and its numbers are memorisation. That does not matter for ranking
+models — it is the same constant under all of them.
+
+## Reading the output
+
+`correspondent_offered` against `correspondent_recognised` is the
+`MATCH_THRESHOLD = 0.8` gap: the model names the right entity and difflib
+rejects it. Measured, not hypothetical — "GOTOOLS GmbH" against the stored
+"GOTOOLS" scores ~0.74 and is thrown away despite being an exact prefix.
+
+`type_specific` against `type_catchall` splits on whether the true type is
+"Sonstige", which holds 1133 of ~3900 documents and is the one label with no
+semantic content. A model reading the document has to infer "none of the above".
+
+`failed` counts documents where the model produced nothing usable. With
+`--n-predict 768` in place, that is mostly non-termination: paperless reports
+the truncated response as a flat `Invalid AI configuration` and discards the
+content, so what the model was doing is visible only in the llama-server log.
+
+## Results so far
+
+| model | corr. offered | corr. recognised | type | specific | catchall | failed | seconds |
+|---|---|---|---|---|---|---|---|
+| *classifier (reference)* | 72.0 | 72.0 | 100.0 | 100.0 | 100.0 | 0 | 18 |
+| Qwen3.6-35B-A3B Q4_K_M | 72.9 | 77.1 | 85.4 | 94.9 | 44.4 | 2 | 5494 |
+| Ministral-3 3B Q4_K_M | 71.4 | 76.2 | 76.2 | 83.3 | 33.3 | **29** | 5511 |
+| Ministral-3 8B Q4_K_M | — | — | — | — | — | 3/3 | aborted |
+| Granite 3.3 8B Q4_K_M | — | — | — | — | — | all | not measurable |
+
+Read the Ministral-3 3B row with its failure count, not without it. It scored 21
+documents and failed 29 — and on those 21 its correspondent numbers sit within
+the noise floor of Qwen3.6's. That is not a near-tie: the 21 are the documents
+it could answer at all, which is a set selected for being easy, and the
+classifier does better on them too (11 of 21 both right against 30 of 48).
+A model that declines three documents in five has no usable accuracy number.
+
+Qwen3.6 complement: 30 both right, 5 rescued, 4 broken, 9 both wrong — and two
+of those four "broken" are the difflib gap above, not model errors.
+
+### How big a difference means anything
+
+Qwen3.6 was measured twice over the same 50 documents, once with the deprecated
+--chat-template-kwargs and once with --reasoning off:
+
+    70.8 / 75.0 / 83.3 / 94.9 / 33.3   two failures
+    72.9 / 77.1 / 85.4 / 94.9 / 44.4   two failures
+
+Every one of those gaps is a single document out of 48 — the catchall one is
+one document out of nine. So that is the noise floor: **a difference between
+two candidates smaller than about two documents says nothing.** Decoding is
+sampled, and the same model on the same input does not give the same answer
+twice.
+
+Worth knowing before reading a 2-point lead as a result.
+
+## The instrument is checked, not assumed
+
+Every AI run asks the model "Nenne die Hauptstadt von Frankreich" before the
+documents, every ten documents, and again if it aborts. If Paris does not come
+back, the run stops and says so.
+
+This exists because a whole day of results turned out to be measuring a broken
+instrument. On this Vulkan stack a prompt past some model-specific length stops
+llama.cpp producing language — it repeats one token, " de de de" or
+" phosphorus phosphorus" or whitespace — at HTTP 200 with finish_reason "stop"
+and nothing in the log. The slot then stays broken for every request after it
+until the pod restarts.
+
+So a run against a poisoned slot reports fifty failures that are one event, and
+reads exactly like a model that cannot classify. Six candidates were written up
+that way. gemma-4-26B-A4B answers "Die Hauptstadt von Frankreich ist Paris."
+perfectly on a fresh pod and produces whitespace at a 2334-token prompt; its
+recorded classification scores described a corrupted slot and nothing else.
+
+**A run whose canary breaks is void, not a result.** Failures adjacent to the
+break are one fault. Use `probe-length.sh` to find where the model's boundary
+actually sits before judging it — paperless needs ~5300 tokens.
+
+## Bounds of the harness, not of the model
+
+Two numbers in here are mine and both have produced misleading results:
+
+`--n-predict` caps generation server-side, default 768. A candidate that stops
+exactly there has hit MY bound. Six candidates were written up as incapable on
+that signal before anyone checked whether they would have finished at 900
+tokens. A working answer takes 241-291 tokens, so 768 looked generous — and
+"looked generous" is not evidence.
+
+`EVAL_TIMEOUT` bounds the client, default 300 s. Raising the token cap alone
+just moves the failure here: at 6 tok/s a 4096-token budget needs 620 s of
+generation, so the run fails with TimeoutError instead. Raise both together.
+
+    ./run-candidate.sh <label> <sample> <n_predict> <timeout>
+    ./run-candidate.sh gemma4-26b-a4b 3 4096 900
+
+The Q8 precision comparison had to be thrown away over this. Q8's uncapped
+answers run 460-520 tokens against Q4's 280-443 — about 60% longer for the same
+task — so 20 of 50 documents hit the 768 cap against Q4's one, and the run
+looked like "Q8 classifies worse" when it measured "Q8 is wordier than my
+bound". Before comparing two configurations, check that neither is sitting on
+the cap.
+
+## What to watch for
+
+**Prompt length.** Past roughly 14k tokens this stack stops producing language
+and starts producing garbage or nothing, without any error — and a single such
+request poisons the llama.cpp slot until the pod restarts. Paperless prompts sit
+near 5k, but the 252 documents over 14000 characters push toward the boundary
+with their RAG neighbours. A run that starts scoring zeros mid-way is more
+likely this than the model.
+
+**Ground truth.** It is the current filing, and over ten years conventions
+change. A disagreement with an old document is not automatically an error.
+
+## The models volume fills up
+
+Each candidate leaves its weights on the shared `llama-models` PVC — 2.5 GB for
+a small dense model, 17-25 GB for an MoE, 34 GB for a Q8. The volume is 120 GiB
+and nine screened candidates filled it completely.
+
+A full volume does not announce itself. llama-server cannot write its metadata
+cache, so it cannot resolve the repository listing, and says:
+
+    no GGUF files found in repository <repo>
+    Available GGUF files:
+      - <whatever it had cached before the disk filled>
+
+which reads as a wrong model reference. The pod then sits in
+`Init:CrashLoopBackOff`, which from outside is indistinguishable from a slow
+34 GB download. Two jobs spent three hours that way.
+
+**Check `df -h /models` before believing anything llama-server says about a
+repository.** Clear out rejected candidates when the volume gets tight — the
+weights are re-downloadable, so deleting them costs only bandwidth:
+
+```sh
+kubectl -n paperless-eval exec <a pod mounting llama-models> -- \
+  sh -c 'cd /models && du -sh * | sort -h'
+```

+#
+#     Qwen3.6-35B-A3B Q4_K_M   ~21 GB   11.0 tok/s
+#     Qwen3.6-35B-A3B Q8_0     ~34 GB   10.3 tok/s
+#
+# Doubling the bytes per active parameter cost ten percent, not half. So decode
+# is NOT bandwidth-bound for this MoE — it is compute-bound on many small
+# per-expert matmuls, which also explains the earlier measurement of 21.4 GB/s
+# effective against a 53.9 GB/s ceiling: it was already leaving 60% of the bus
+# unused.
+#
+# Consequences: the bytes-per-token formula predicts dense models and not this
+# one, and higher precision is nearly free on an MoE here — about 10% slower
+# for double the weight precision.
+#
+# So the order to prefer is: MoE with few active parameters, then dense 3-9B,
+# then dense 10-14B only for an exceptional model (~4 tok/s, roughly three
+# hours for 50 documents), and nothing dense above 14B.

+# WHAT THE RESEARCH RULED OUT, so nobody re-derives it
+#
+# Hard-excluded on tool calling, chat template inspected directly rather than
+# assumed — the string "tool" appears zero times in any of them:
+#   Gemma 3, every size (4B/12B/27B)   phi-4 14B (the mini DOES have it)
+#   Cohere Aya, all variants           InternLM 2.5 / 3
+#
+# Hard-excluded on German, stated by the vendor rather than merely missing:
+#   Falcon 3 — "supports EN, FR, ES, PT", German is not on the list
+#   EXAONE — the small ones are English/Korean; the ones with German are 33B+
+#
+# German fine-tunes are a dead end, and for one consistent reason: SauerkrautLM,
+# DiscoLM, LeoLM, Occiglot and Teuken all overwrite their base model's chat
+# template with a minimal ChatML loop that drops tool calling. VAGOsolutions
+# does this even on bases that have it (Llama-3.1, Qwen2.5). Assume any German
+# tune is tool-incapable until its own tokenizer_config.json says otherwise.
+#
+# On llama.cpp's tool parsing, which explains the Granite failure: current
+# builds have no per-vendor parser table any more. common/chat.cpp exposes
+# PEG_SIMPLE / PEG_NATIVE / PEG_GEMMA4 / PEG_MINIMAX_M3 and derives the grammar
+# from the model's own template. Hermes-style <tool_call> JSON is a first-class
+# tested fixture in tests/test-chat.cpp; Granite's format is not. So this is not
+# "Granite is unsupported" so much as "Granite's template shape is outside what
+# the auto-parser was validated against".
+#
+# SCREENING RESULTS, and a pattern that reframes the whole search
+#
+#   qwen35        MoE 35B total / 3B active   works, 2 of 50 failed
+#   qwen3-8b      dense 8B                    4 of 5 failed
+#   hermes4-14b   dense 14B                   3 of 3 failed, aborted
+#   ministral8b   dense 8B                    3 of 3 failed, aborted
+#   ministral3b   dense 3B                    29 of 50 failed
+#   granite8b     dense 8B                    every document failed
+#
+# Five dense models from 3B to 14B cannot produce a valid call against
+# paperless's 14-field schema; the one mixture-of-experts model can. Hermes is
+# the cleanest of these failures: its <tool_call> JSON is an explicitly tested
+# fixture in llama.cpp's own test suite, so the parser demonstrably handles the
+# format and the failure has to be the model.
+#
+# Working hypothesis: holding a long grammar-constrained structure needs model
+# capacity, and what supplies it is TOTAL parameters, not active ones. If that
+# is right, "go smaller for speed" is a dead end here — and the consolation is
+# that the fastest shape on this hardware, MoE with few active parameters, is
+# also the only one that works.
+#
+# qwen3-30b-a3b tests it directly: 30B total, 3B active.
+#
+# CORRECTION: Gemma is not excluded after all. Gemma *3* has no tool support —
+# "tool" appears zero times in its chat template at every size, checked
+# directly. Gemma *4* 26B-A4B does have it, documented in the template, plus
+# "140+ languages pretrained, 35+ out of the box". Excluding a family by its
+# previous generation was sloppy.
+#
+# Two of these carry a Vulkan risk worth checking in the llama-server log
+# before trusting a run: Nemotron-3.5 interleaves real Mamba2 layers and
+# Qwen3.5 uses DeltaNet linear attention, and llama.cpp's Vulkan SSM shaders
+# are less exercised on Iris Xe than on Arc. Issue #19957 reported exactly this
+# for Qwen3.5-35B-A3B and it turned out to be a stale build, fixed months
+# before b10731 — but confirm layers are actually offloaded rather than
+# silently falling back to CPU, which would read as a slow model.
+#
+# Ruled out after checking: ERNIE-4.5-21B-A3B (only the Thinking variant has
+# tool calling; the instruct one has none), Ling-3.0-flash (124B total),
+# Granite-4.0-H-Small (9B active), DeepSeek-V2-Lite and OLMoE (under 20B
+# total), Cohere North Mini (code-only, no ggml-org/bartowski conversion,
+# cohere2_moe support in llama.cpp unverified), gpt-oss-20b (a reasoning-effort
+# model in Harmony format rather than plain instruct).
+#
+# THE MoE HYPOTHESIS IS DEAD. qwen3-30b-a3b — MoE, 30B total, 3B active, the
+# shape that was supposed to explain everything — scored 1 of 5 and failed 4,
+# indistinguishable from the dense 8B.
+#
+# So neither architecture nor size predicts success:
+#
+#   Qwen3.6-35B-A3B   MoE 35B/3B   Apr 2026   2 of 50 failed
+#   Qwen3-30B-A3B     MoE 30B/3B   older      4 of 5 failed
+#   Qwen3-8B          dense 8B     older      4 of 5 failed
+#   Hermes-4-14B      dense 14B    —          3 of 3 failed
+#
+# The only thing correlating with success so far is how new and how strong the
+# model is. That is an unsatisfying hypothesis because it predicts nothing
+# cheaply — but it is what the data says, and two architectural theories have
+# already died here.
+#
+# qwen35-35b-a3b isolates it: same architecture, same total and active
+# parameters as the working baseline, one generation older. If it fails, the
+# generation is the variable and shape is noise.
+#
+# qwen35-35b-a3b PASSES the screen: 5 of 5, no failures, 584 s. So the
+# generation hypothesis is dead too — Qwen3.5 is a generation OLDER than the
+# working Qwen3.6 and handles the schema cleanly.
+#
+# What the two working models share is 35B total parameters; the one failing
+# MoE has 30B. But that is confounded — Qwen3-30B-A3B is both smaller and
+# older, and three data points cannot separate the two.
+#
+#   Qwen3.6-35B-A3B   35B total   newest   works
+#   Qwen3.5-35B-A3B   35B total   older    works
+#   Qwen3-30B-A3B     30B total   oldest   4 of 5 failed
+#
+# glm47-flash separates them: 30B total, newest generation. If it works,
+# generation is what matters and 35B is not a threshold. If it fails, total
+# size is, and the search should stop looking below ~35B.
+#
+# PREFILL SPEED IS A SELECTION CRITERION AND I WAS NOT TRACKING IT.
+# Measured on this hardware, prompt processing varies more than sixfold across
+# architectures, and it is roughly half of a run's wall clock:
+#
+#   dense 8B (Ministral)        240 tok/s
+#   Qwen3.6-35B-A3B             100 tok/s
+#   GLM-4.7-Flash                31 tok/s   decode 4.9 tok/s
+#
+# GLM-4.7-Flash is disqualified on that alone. At 31 tok/s a 5300-token prompt
+# takes 168 s, times ~2.6 requests per document, is over seven minutes per
+# document and about six hours for a run — before considering whether its
+# answers are any good.
+#
+# It also shows why the 300 s REQUEST_TIMEOUT needs care: 4453 prompt tokens at
+# 31.5 tok/s plus 768 generated at 4.9 tok/s is 298 s, so a slow model turns a
+# content failure into a TimeoutError and muddies the diagnosis. Read the
+# llama-server timings, not just the eval error.
+#
+# glm47-flash: aborted, 3 of 3 — but every one a TimeoutError, not an invalid
+# answer, so this does NOT settle the size-versus-generation question it was
+# started to settle. It failed on speed. Document 1 did reach the --n-predict
+# cap without producing a call, but 2 and 3 were cut off by the 300 s client
+# bound before anything could be concluded about them.
+#
+# Disqualified regardless: 31 tok/s prefill and 4.9 tok/s decode is over seven
+# minutes per document and about six hours for a full run.
+#
+# gemma4-26b-a4b is the better discriminator — 26B total, well under 35, and
+# newest generation. Works means generation and quality matter rather than a
+# 35B threshold; fails is consistent with total size being the line.
+#
+# gemma4-26b-a4b: aborted, 3 of 3, all HTTP 400 rather than timeouts, and the
+# server log shows it ran to the --n-predict cap on every one. So it is the
+# same capability failure as the small dense models, not a template mismatch.
+# (Prefill 45-50 tok/s, decode 6 tok/s — also not fast.)
+#
+# THE SIZE THRESHOLD SURVIVED ITS FIRST REAL TEST. gemma-4 was chosen
+# specifically because it could refute it — newest generation, 26B total — and
+# it did not:
+#
+#   Qwen3.6-35B-A3B   35B   newest    works
+#   Qwen3.5-35B-A3B   35B   older     works
+#   Qwen3-30B-A3B     30B   oldest    fails
+#   gemma-4-26B-A4B   26B   NEWEST    fails
+#   Hermes-4-14B      14B   —         fails
+#   dense 3-8B        —     —         fail
+#
+# Two generations work at 35B total; everything at 30B and below fails,
+# including the newest model in the field. Operating rule until something
+# contradicts it: do not spend a screening slot on anything under ~35B total.
+#
+# Not pinned further on purpose. Whether the line sits at 31B or 34B is
+# interesting and not decision-relevant — there are two working candidates and
+# the useful next number is a full 50-document run of the second one.
+#
+# Re-enabled for length probing, not for scoring. Their classification numbers
+# were taken against a slot that may already have been corrupted, so the only
+# honest thing to do with them is find out where each one's boundary sits.

+"""Measure what Paperless suggests for documents whose labels a human already chose.
+
+Runs both engines against the same documents:
+
+    /api/documents/<id>/suggestions/      the built-in scikit-learn classifier
+    /api/documents/<id>/ai_suggestions/   the LLM path, with RAG
+
+WHAT THIS ANSWERS, AND WHAT AN EARLIER VERSION DID NOT
+
+The two engines are not alternatives — the classifier costs 0.6 s per document
+and keeps running whatever the LLM does. So the useful question is not "which
+scores higher" but "what does the LLM add where the classifier is wrong", and
+that cannot be recovered from two aggregate percentages: 74% and 72% could
+overlap almost entirely or barely at all, and the difference between those two
+worlds is the entire value of running an LLM.
+
+So every document is written out individually, with both engines' verdicts, and
+the summary is derived from that rather than counted along the way.
+
+SCORING
+
+Correspondent and document type are each scored twice:
+
+    offered      the true label's id came back in `correspondents` /
+                 `document_types` — what the UI actually presents
+    recognised   also counting the true label's name appearing wordwise in
+                 `suggested_correspondents` / `suggested_document_types`
+
+The gap between them is one specific failure: the model names the right entity
+but paperless_ai.matching cannot resolve it, because difflib runs at
+MATCH_THRESHOLD = 0.8 and a correct but more verbose answer falls below it —
+"Generali Deutschland Krankenversicherung AG" against the existing "Generali
+AG". Reporting only the first blames the model for a matcher problem; only the
+second claims a usefulness the UI does not deliver.
+
+Document type is additionally split on whether the true type is "Sonstige",
+which holds 1133 of ~3900 documents and is the one label with no semantic
+content — a restaurant reservation lands there because nothing else fits. The
+classifier can memorise that; a model reading the document has to infer "none
+of the above". Scored separately rather than dropped, because the model does
+sometimes get it right.
+
+GROUND TRUTH
+
+The current filing, which deserves care: over ten years conventions change, and
+a disagreement with an old document is not automatically an error. Treat the
+comparison between engines as the result and the absolute numbers as
+indicative.

+# THE TEST THAT SHOULD HAVE COME FIRST. On this Vulkan/Iris Xe stack every
