-      # and a full OpenAI-compatible API to anyone who can reach the port. That
-      # is why it was LAN-only until now. This gate is what makes a public
-      # hostname defensible: the outpost terminates every request, enforces the
-      # session, and only then forwards to llama-server.
-      #
-      # Same reasoning as vscode-gate, and the same passkey step-up: what sits
-      # behind the gate is entirely unprotected, so the gate is the whole of the
-      # access control rather than a second factor on top of an app login.
-      #
-      # In-cluster consumers (Home Assistant, Paperless, CI) are unaffected:
-      # they address llama-server.ai.svc.cluster.local directly and never pass
-      # through Traefik or this outpost.
-      #
-      # No group and no policy binding: any user who can authenticate gets in,
-      # as with Immich, Audiobookshelf, Home Assistant and Music Assistant. The
-      # gates that pin membership to a named user in git — vscode, esphome,
-      # zigbee2mqtt, shelly-manager, prometheus — are admin interfaces, where
-      # the allowlist is the point. A chat UI is not one of those, and deciding
-      # its membership here would put an access-control choice in a manifest

-# Single-model rather than router mode. Router mode served chat and embeddings
-# from one port, but two things made that wrong here:
-#
-#   1. Its /health answers 200 as soon as the router process listens, while the
-#      models are still downloading behind it. Kubernetes marked the pod Ready
-#      within seconds of start, so traffic arrived at a server that could not
-#      answer. In single-model mode /health returns 503 until the model is
-#      resident, which is what the probes below actually need.
-#   2. Every model on the port is selectable in the built-in WebUI, including
-#      the embedding model. Asking an embedding model to chat returns fluent
-#      nonsense ("capital capital capital ...") rather than an error, and
-#      `--embeddings` does not prevent it. There is no flag to hide a model
-#      from the list — `--tags` is informational and `--ui-config` only sets UI
-#      preferences — so the only way to keep it out of the picker is to keep it
-#      off this endpoint. It runs in embed.yaml 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.

-# Retrieval evaluation for an embedding model, on German documents of the kind
-# this homelab actually files.
-#
-# Companion to scripts/ai-eval.sh, but it cannot work the same way. A chat
-# answer can be read and judged; an embedding is 1024 opaque numbers. What is
-# measurable is whether the right document comes back first, so this builds a
-# small labelled corpus, embeds it, and scores real questions against it.
-#
-# Metrics:
-#   Recall@1  the correct document ranked first — what Paperless's RAG actually
-#             feeds to the classifier
-#   Recall@3  it at least made the shortlist
-#   MRR       mean reciprocal rank, so near-misses are visible rather than
-#             collapsing to pass/fail
-#   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
-# documents that are all "Rechnungen", a car insurance and a vehicle
-# registration sharing a number plate. An easy corpus would rate everything 100%
-# and tell you nothing.
-#
-# Usage:
-#   scripts/embed-eval.sh                                    # cluster default
-#   scripts/embed-eval.sh -m some-model
-#   scripts/embed-eval.sh -e https://host/v1/embeddings -m model -k KEY
-#
-# Env equivalents: EMBED_EVAL_ENDPOINT, EMBED_EVAL_MODEL, EMBED_EVAL_KEY.
-#
-# To compare two models on our llama-embed, -m is not enough: swap --hf-repo in
-# kubernetes/apps/llama-server/embed.yaml, let it roll out, then re-run. Note
-# that changing the model also invalidates any vectors Paperless has stored, so
-# comparisons are best made before an index exists.
-#
-# Exit code is the number of queries whose correct document did not rank first.
