feat(frank-dragoon): open the NPU node the way rootless can actually reach it

The armed boot reached the engine and died in its own preflight: halogen npu: /dev/accel/accel0 is here, but this process cannot open it (crw-rw---- nobody:nogroup). The node is root:render 0660 and a rootless container maps exactly one uid/gid, so `render` is unmapped inside it and `--group-add keep-groups` — the vendor's advice, and the ComfyUI pattern for /dev/kfd — cannot grant a group the namespace does not map. Measured 2026-10-19 from a `dank` shell already in `render`: without the flag denied, with the flag denied, with the udev mode 0666 the open succeeds (OPEN_OK). Same wall 99-comfyui-gpu-access.rules already solved for the GPU compute nodes, so the accel node gets its counterpart: dankclaw/udev/98-halogen-npu-access.rules — KERNEL=="accel[0-9]*", SUBSYSTEM=="accel", MODE="0666" The deployer installs the rule, reloads rules, re-triggers the node and only then checks the mode; the serve script refuses any node that is not other-writable, naming the rule, so this cannot return as a crash loop (189 restarts while chat was down is the failure mode being closed). Both checks read the permission bit directly: `[ -o FILE ]` is not "other-writable" — it means "exists" and `-o` doubles as the OR operator inside test, which is why the first cut of the gate refused everything. Dragoon seam: 33 -> 35 tests. The fixture node is 0666 like the installed one, a 0660 node is refused with the rule named and nothing rendered, and the rule file's shape plus the deployer's install/trigger are asserted.
fix(deploy): the dragoon gate reads the deployer's own payload-dir twin

+
+### 2026-10-19: which published ports a rootless container can actually dial
+
+Probed from inside `open-notebook` (rootless, on `dankclaw_default` **and** the
+private `systemd-open-notebook`), each address aimed at a live listener:
+
+| Dial | Result | Mechanism |
+|---|---|---|
+| `192.168.0.143:3000` (Gitea) | **200** | published by a **rootless** container — rootless egress crosses the host netfilter where netavark installed that DNAT |
+| `192.168.0.143:7770` (`frank-dragoon`) | refused | the container is **rootless on podman's default `pasta` netns** (the root unit's `User=dank` runs `podman run`, so it lands in dank's storage). Pasta forwards the published port in the host netns — the host and the LAN both answer 200 — but installs no netavark DNAT for traffic arriving from a rootless bridge, so the same address is refused from a container. This is NOT a root/rootless rule-set split: `podman ps` as `dank` lists it |
+| `host.containers.internal:7770` (`169.254.1.2`) | **200** | the pasta forwarder is bound `0.0.0.0` on the host, so the gateway alias reaches it — and the alias is link-local, which is the dead end below |
+| `192.168.0.143:7771` (`frank-zealot`) | refused | host-netns listener, unpublished — the rule above, reconfirmed |
+| `10.89.1.1:7771` | refused | the bridge gateway address belongs to the rootlesskit netns, not to the host |
+| `host.containers.internal:7771` (`169.254.1.2`) | **200** | the gateway alias is the one address that carries a rootless container to a host-netns listener. Why `hermes-dashboard` timed out on this alias in 2026-09-02 while `open-notebook` answers today is **not established**; the difference to check first is the second network and where the default route lands |
+| `192.168.0.235:7770` (`frank-archon`) | **200** | a different machine: plain routing, no DNAT in the path |
+
+The consequence that changes designs: **a rootless container's menu of local model
+endpoints is `frank-tts` (container DNS, same network) and `frank-archon` (LAN
+address on another host).** A `pasta` endpoint has no address an app container can
+use: the LAN address is refused, and the one alias that answers is link-local,
+which some applications refuse to store at all ([[Open Notebook]] meets exactly
+that refusal). Pasta cannot be *added to* either —
+
+```
+podman run --network pasta --network dankclaw_default …
+Error: cannot set multiple networks without bridge network mode, selected mode pasta
+```
+
+so the only shape that makes such an endpoint nameable is **moving it onto
+`dankclaw_default`** (`FRANK_DRAGOON_NETWORK` in `scripts/frank-dragoon.env`,
+2026-10-19). For frank-dragoon that is not an exposure change: the engine's
+unauthenticated token port binds the container's **own loopback**
+(`/proc/net/tcp` on 2026-10-19: `127.0.0.1:8730`, `0.0.0.0:8731`), so only the
+API port becomes name-resolvable, which is the same trust the published 7770
+already carries on the LAN. `frank-zealot` (7771) stays a host-netns binary and
+remains unreachable except through the link-local alias.

-open-notebook ([lfnovo/open-notebook](https://github.com/lfnovo/open-notebook)) is the notebook layer that turns existing notes and sources into a **spoken episode**: an outline, then a dialogue transcript, then one synthesized clip per speaker turn, concatenated with ffmpeg into an MP3.

-**It is NOT deployed.** This page documents repo-owned configuration — the Quadlet units, the env file, the deployer path, the homepage card — and the contract those files were written against. On 2026-10-18 no `open-notebook` or `open-notebook-surrealdb` container exists on Dankclaw (`podman ps -a` census, 2026-10-18), and the homepage card ships `wip: "down"` with `showLink: false`, so the card is hidden and reported `wip-down`. Re-censused 2026-10-19 and unchanged: no `*notebook*` unit in `systemctl --user list-unit-files`, nothing installed under `~/.config/containers/systemd/` by that name, no container in `podman ps` — the repo's three quadlet files have never been installed on the host. Deploying it is a deliberate next step, not a pending one.
+**Deployed 2026-10-19.** Both units installed and `active`, both containers healthy, SurrealDB migrated to v25 on first boot, and the first episode rendered end to end: a note in, an outline, 23 dialogue turns, 23 clips, and one **747-second MP3 on the host bind, produced in 301 seconds** — about 2.5× real time with every concurrency knob at 1. The download route answers `200 audio/mpeg` with the bearer token and **401 without it**. It is guarded like every other user service — `https://notebook.franksdank.cloud`, Anubis → Authentik → the app's own login — and the API is no longer published on the LAN at all.

+## The guard chain, and the single origin
+
+`notebook.franksdank.cloud` follows the fleet's exposure policy in this order, and the order is the law ([[Network Architecture]]):
+
+1. **Provider first.** Authentik proxy provider `notebook-proxy` existed before any route pointed at the app: `external_host https://notebook.franksdank.cloud/` (exact vhost, trailing slash), `internal_host http://caddy:8017`, the three flows copied from `embedded-outpost`, Application `Open Notebook` (`notebook-guard`), and the provider attached to the embedded outpost's provider set. Flip the vhost first and authenticated traffic lands on the outpost's error page. Verify after the change that the outpost logged no `Failed to fetch outpost from API` (the null-flow wedge) and that an already-guarded vhost still answers.
+2. **Then the route, in one deploy:** the guarded site block (`reverse_proxy anubis:8923` with `header_up X-Real-Ip {remote_host}` — the whole request, so no path ever reaches the app unchallenged) plus the post-auth `@notebook` handler on `http://:8017`, plus the LAN record in `dankclaw/pihole/addn-hosts`. The public Porkbun A record is a host action, not a repo file.
+3. **One upstream, not two.** `reverse_proxy 192.168.0.143:8502`: the image's own Next.js layer rewrites `/api/*` to the FastAPI beside it (`next.config.ts`, `INTERNAL_API_URL` default `http://localhost:5055`), so the API needs no route and no outward face — hence `127.0.0.1:5056`. Caddy dials the published LAN port rather than a container name because this Caddy lives in root's Podman and cannot see a rootless container at all ([[Container Network Namespaces]]). SSE (`/api/search/ask`, chat) streams through the same bare proxy that carries OpenWebUI's chat at `ai.franksdank.cloud`; no `flush_interval` or timeout directive is needed, and adding a route timeout is precisely what would cut it.
+4. **`API_URL` must name the vhost.** `GET /config` (the Next route) answers in priority order: `API_URL` env → autodetect from `Host` + `X-Forwarded-Proto` → `http://localhost:5055`. Autodetect appends **`:5055`**, a port that belongs to seerr on this host, so leaving `API_URL` unset hands the browser an address nothing answers and every call fails under a UI that loaded fine. `CORS_ORIGINS` is set to the same single origin only to keep the app from defaulting to `*`. `scripts/open-notebook.env` carries both.
+
+The app's own login stays on behind the chain. It is not redundant: publishing the API on loopback does **not** hide it from this host's other containers, which can dial `open-notebook:5055` by name on `dankclaw_default`. The chain decides *who from outside* gets in; `OPEN_NOTEBOOK_PASSWORD` decides what anything that already reached the port may do.

 One container, three processes under supervisord (`supervisord.conf` upstream): `uvicorn api.main:app --port 5055` (`:12`), the job worker (`:25`), and the Next.js frontend (`:39`). Two consequences the config depends on:

 `DATA_FOLDER` is hard-coded `"./data"` (`open_notebook/config.py:5`) and `PODCASTS_FOLDER` is `"./data/podcasts"` (`:19`); the database stores each episode's audio path **relative** to that folder (`episodes/<uuid>/audio/<uuid>.mp3`), and the download route is `GET /api/podcasts/episodes/{id}/audio`. That is why covering one subdirectory with a bind mount is sufficient — nothing in the database has to change if the mount moves.

+## What is provisioned (REST, 2026-10-19)

-Credentials are stored in the database, encrypted, and are **not expressible in env or a Quadlet file**. The sequence is one-time, in **Manage → Models**, and both entries use provider type **OpenAI Compatible** (upstream: any server that implements `/v1/audio/speech` works this way — `docs/5-CONFIGURATION/local-tts.md:5`).
+Credentials live in the database, encrypted with `OPEN_NOTEBOOK_ENCRYPTION_KEY`, and are **not expressible in env or a Quadlet file** — the UI (**Manage → Models**) or the REST API are the only doors. Both use provider type `openai_compatible`, because any server that answers `/v1/audio/speech` or `/v1/chat/completions` works through it (`docs/5-CONFIGURATION/local-tts.md:5`).

-1. **TTS credential** — base URL **`http://frank-tts:7772/v1`**. The `/v1` is part of the URL: the client posts to `<base_url>/audio/speech`, so a base URL without `/v1` 404s on every dialogue line (`local-tts.md:72-80`, the base-URL table, always carries `/v1`). `frank-tts` resolves by container name because the app is attached to `dankclaw_default`, the network frank-tts's unit joins (`dankclaw/voiceservice/quadlet/frank-tts.container:51-52`). If frank-tts is ever moved off that network, the published-port form is `http://192.168.0.143:7772/v1` — a published port is dialable at the host's LAN address from any netns. The API-key field stays empty; frank-tts does not authenticate.
-2. **LLM credential** — base URL **`http://host.containers.internal:7771/v1`**, model row `frank-zealot`. frank-zealot is a **host process** on `0.0.0.0:7771` (`ss -ltn` on Dankclaw shows the listener with no container owning it, 2026-10-18), and on this netavark host a bridge container reaches the host's LAN IP only at a *published* port — which is why Prometheus scrapes the same endpoint as `host.containers.internal:7771` (`shared/prometheus/prometheus.yml:89-111`, "not their own LAN addresses"). See [[Container Network Namespaces]]. `http://192.168.0.143:7771/v1` is the variant to try only if the gateway name ever stops resolving; it is expected to be refused from a bridge netns.
-3. **Model rows are created by name.** Discovery is optional (see the next section): type the model id and confirm the add. One base URL per credential, so the TTS and LLM credentials are necessarily two separate configurations.
+| Record | Value |
+|--------|-------|
+| Credential `frank-tts` | modality `text_to_speech`, base URL `http://frank-tts:7772/v1`, no API key (the shim does not authenticate) |
+| Credential `frank-archon` | modality `language`, base URL `http://192.168.0.235:7770/v1` |
+| Model row `voxcpm2` | type `text_to_speech` on the frank-tts credential. The name is decorative: frank-tts ignores the request's `model` field and synthesizes whatever `voice` names ([[Frank TTS]]) |
+| Model row `frank-archon` | type `language`; `PUT /api/models/defaults` points chat, transformation and large-context at it. **The embedding default stays null — nothing in the fleet serves `/v1/embeddings`** |
+| Speaker profile `dank-duo` | two speakers, Frank → `voice_id: narrator1`, Comrade → `narrator2`, `voice_model` = the TTS row |
+| Episode profile `dank-daily` | `num_segments: 4`, `speaker_config` = `dank-duo`, outline and transcript LLM = the archon row, briefing that ends "Never invent numbers." |

-**Verify reachability before saving**, from inside the container, because both addresses are netns-dependent:
+Order that works over REST: credentials → model rows (`POST /api/models` with `credential: <credential id>`) → `PUT /api/models/defaults` → speaker profile (`voice_model: <model id>`) → episode profile (`speaker_config` / `outline_llm` / `transcript_llm`). `POST /api/models/{id}/test` proves each row: the language row answered with a real completion from frank-archon; the TTS row reached frank-tts and came back `unknown voice 'alloy'; available voices: narrator1, narrator2, narrator3` — the app's own test path hard-codes an OpenAI voice, so that message *is* the proof the leg works.
+
+**`POST /api/podcasts/generate` takes profile NAMES, not record ids.** `episode_profile: "dank-daily"` works; the `episode_profile:…` id returns a bare `500 Failed to submit podcast generation job`, and the actual reason (`Episode profile '<id>' not found`) appears only in `podman logs open-notebook`.
+
+**The scriptwriter is frank-archon, not the planned frank-zealot, because two rules collide on the address.** Measured from inside the app's netns 2026-10-19:
+
+- `192.168.0.143:7771` (frank-zealot, a host-netns listener) and `192.168.0.143:7770` (frank-dragoon, a **root**-published port) both refuse the connection; `host.containers.internal:7771` answers. Full census: [[Container Network Namespaces]].
+- The app refuses to **store** that one working address: its URL guard rejects any base URL that resolves inside link-local `169.254.0.0/16` (`open_notebook/utils/url_validation.py`, "Link-local addresses are not allowed (metadata endpoints)"), unconditionally — no env var touches it, and `AddHost=` cannot dodge it because the check runs on the resolved address.
+
+`http://192.168.0.235:7770/v1` — another machine, plain RFC1918 — is the only fleet LLM address that passes both tests. Cost: frank-archon runs `--max-num-seqs 2` and the operator session itself lives there, so a render is a slow-down for whoever else is talking to that endpoint, not a stall; `ESPERANTO_LLM_TIMEOUT=180` covers an outline or transcript call comfortably.
+
+**frank-dragoon can write transcripts, but only greedily — and open-notebook cannot ask for greedy.** Measured 2026-10-19 against the live endpoint: `response_format` as `json_schema` or `json_object` returns schema-valid JSON at `temperature: 0` and a **400** at any sampled temperature — halogen decodes greedy under a schema, and because its sampler default is server-side, omitting `temperature` is sampled, not greedy. That 400 is the trap: esperanto's `is_json_schema_unsupported_error` matches the words *not implemented* in it, so `_SchemaFallbackModel` in `podcast_creator/nodes.py` reads it as "this endpoint has no schema support", downgrades to `json_object`, gets the same 400, and **fails the run** — esperanto's own rescue (drop `response_format` entirely) fires only on the different message `'response_format.type' must be 'json_schema'`. The full law is on [[frank-dragoon]]. And the fix is not reachable from here: a model record is `{credential, name, provider, type}` and a model response adds only timestamps (`GET /openapi.json`, `ModelCreate`/`ModelResponse`) — **there is no per-row config field**, no way to attach `temperature: 0` to one row from the UI or the API. Making `frank-dragoon` the writer would therefore need something in the path that rewrites request bodies, which is a heavier tenant than the contention it removes. **frank-archon stays the scriptwriter.** Reachability would be a separate problem anyway: `frank-dragoon` is not on `dankclaw_default` (the serve script passes no `--network`), so nothing on this network has a name for it, and the one address that does answer — `host.containers.internal:7770` — is the link-local the guard refuses to store ([[Container Network Namespaces]]).
+
+**No embedding model is deployed, and saving a note is where that shows up.** Every note save submits an `embed_note` command that fails in the worker with `No embedding model configured. Please configure one in the Models section.` The note itself is stored and readable; semantic search, source ingestion and notebook-context questions stay dead until something serves `/v1/embeddings`. Podcast generation from `content` does not need embeddings, which is why renders work today. The cheapest door is **halogen's NPU lane, not a new endpoint**: `qwen3-embedding-0.6b` is already in the catalog of the image `frank-dragoon` runs and answers `/v1/embeddings` on the same port (1024 unit-length floats; the instruct prefix goes in the text, and `check_embedding_ctx_length=False` for LangChain). What enabling it costs — the accel device, the host XRT mount, and the fabric-clock hold that GPU+NPU co-run requires — is on [[frank-dragoon]]; after that, the embedding row still has to clear the reachability rule above.
+
+**Secrets never go in a command line.** The API's bearer token *is* `OPEN_NOTEBOOK_PASSWORD`, and a `-H "Authorization: Bearer …"` argument is world-readable in `/proc/<pid>/cmdline`; put it in a mode-600 curl config and pass `-K`:

 ```bash
-podman exec open-notebook curl -sS http://frank-tts:7772/health
-podman exec open-notebook curl -sS http://host.containers.internal:7771/v1/models
+PW=$(grep -m1 '^OPEN_NOTEBOOK_PASSWORD=' /home/dank/Containers/open-notebook/env | cut -d= -f2- | tr -d '"')

+curl -s -K "$cfg" http://127.0.0.1:5056/api/models | head -c 400
+rm -f "$cfg"
 ```

-**The blocker moved; it did not vanish.** frank-tts and frank-tts-engine are **deployed** (2026-10-18) and answer on 7772, so the voice leg works end to end — `podman exec open-notebook curl -sS http://frank-tts:7772/health` is the check to run the day the app exists. What still blocks a render is open-notebook itself: not installed on this host yet. When it is, the two provider rows above are the only wiring, and the seeded speaker profiles carrying OpenAI voice names are the first trap.
-
-**Why frank-zealot and not frank-dragoon:** podcast scriptwriting asks the model for a JSON-schema response (with a plain-JSON fallback). The decision rests on each endpoint's documented request surface ([[frank-zealot]], [[frank-dragoon]]): zealot's is a known-good target for that call shape, dragoon's structured-output behaviour is **unverified**, so it is the unproven alternative, not the fallback. `ESPERANTO_LLM_TIMEOUT=180` (the app's own default) covers an outline or transcript call on zealot comfortably; upstream's note is to keep it under 600 so a slow call fails with a clear error instead of a UI timeout.

 ## Speakers and voices: 1–4, and the IDs are free text

 The clock next to it: `ESPERANTO_TTS_TIMEOUT` (`:91`) is patience **per dialogue line**, not per episode — a three-minute episode is dozens of separate POSTs, and the tail of a long turn on a CPU engine goes past upstream's 300 s default. It is set to **660, one round-trip outside `SHIM_TIMEOUT=600`** in `scripts/frank-tts.env` (frank-tts's own per-request ceiling): nested budgets go inside-out — the same rule that file states for `LLAMA_TIMEOUT` — so a frank-tts give-up arrives labelled as frank-tts's error instead of the worker's own timeout, and re-measuring frank-tts cannot silently strand this number below it. An abandoned request does not cancel the engine process; it only strands the episode in "generating".

+What the guard costs, measured on that first render (the deployed shape): 23 dialogue clips, one POST each, **10–11 s per clip** with both knobs at 1 → 301 s of wall clock for 747 s of speech, i.e. **2.5× real time**, box still responsive.

 ## Secrets, and the difference between blank and unset

-`OPEN_NOTEBOOK_PASSWORD` unset means **authentication off** (`environment-reference.md:46`) — every API route, including the episode-audio download, answers anyone who can reach the published port. That is a real exposure on a LAN-published service with no vhost and no guard chain in front of it, which is why `deploy_open_notebook` refuses to start either unit unless the seeded host file carries a value for all four secret keys (`OPEN_NOTEBOOK_ENCRYPTION_KEY`, `OPEN_NOTEBOOK_PASSWORD`, `SURREAL_PASSWORD`, `SURREAL_PASS`). `OPEN_NOTEBOOK_ENCRYPTION_KEY` is separately load-bearing: it is **required to save any provider credential**, and changing it later makes stored keys undecryptable (`:44`).
+`OPEN_NOTEBOOK_PASSWORD` unset means **authentication off** (`environment-reference.md:46`) — every API route, including the episode-audio download, answers anyone who can reach it. Moving the API to loopback did not remove that exposure, it only removed the LAN from it: any container on `dankclaw_default` dials `open-notebook:5055` by name, so an unset password is an open episode library to every container on this host, guarded or not.

- **Nothing deployed (today's state):** revert the commits. There is no host state to undo — no unit, no container, no volume, no `/home/dank/media/podcasts` directory beyond what the deployer would create.
- **Deployed:** `systemctl --user stop open-notebook.service open-notebook-surrealdb.service`, then move the three files (`open-notebook.container`, `open-notebook-surrealdb.container`, `open-notebook.network`) out of `~/.config/containers/systemd/` into `~/.AGENTTRASH/` — never `rm` — and `systemctl --user daemon-reload`. The generated units disappear with their sources.
+- **Take it off the air, in the reverse of the deploy order:** delete the guarded site block and the `@notebook` handler from `dankclaw/Caddyfile` and deploy `caddy`; then in Authentik delete the `notebook-guard` Application and the `notebook-proxy` provider and drop it from the embedded outpost's provider set. A **route with no provider 502s** while a provider with no route is inert — that asymmetry is why the chain unwinds Caddy-first.
+- **Stop the app:** `systemctl --user stop open-notebook.service open-notebook-surrealdb.service`, then move the three files (`open-notebook.container`, `open-notebook-surrealdb.container`, `open-notebook.network`) out of `~/.config/containers/systemd/` into `~/.AGENTTRASH/` — never `rm` — and `systemctl --user daemon-reload`. The generated units disappear with their sources.
 - **Kept on purpose:** the `open-notebook-data` and `open-notebook-db` named volumes and `/home/dank/media/podcasts`. Episode audio and the notebook database are user data; removing them is a separate, deliberate act, and episode files are host files precisely so they can outlive the container.
- **Homepage:** the card is `wip: "down"` + `showLink: false`, so retiring the service needs no card surgery beyond setting it back to that state.
+- **Provider credentials are database rows**, encrypted with `OPEN_NOTEBOOK_ENCRYPTION_KEY`; no repo file mirrors them. Regenerating that key while the database volume survives makes every stored credential undecryptable and forces re-entry — so a rollback that keeps the volume keeps the key file with it.
+- **Homepage:** the card test in `tests/open_notebook.bats` pins the live state (`showLink: true`, link = the vhost), so retiring the service edits that test in the same commit as the card flip back to `wip: "down"`.

+## The NPU lane (XDNA2, armed by one env var)
+
+XDNA2 executes only vendor-precompiled AIE partition programs — that is the wall the TTS attempt died at
+([[Frank TTS]]) — and flash-server ships those programs. `HALOGEN_NPU_MODELS=<names>` starts a second engine **in the
+same container behind the same port**, and a request picks one by its `model`; leave the variable out and the server
+is exactly what runs today. The pinned 0.16.2 image already carries the five-program catalog
+(`/opt/halogen/npu/models.txt`: `decider-0.8b`, `qwen3-embedding-0.6b`, `qwen3-reranker-0.6b`, `qwen3guard-gen-0.6b`,
+`qwen3.5-2b`) and `docs/NPU.md` at tag `v0.16.2` documents it, so **`/v1/embeddings` is one env var and three mounts
+away — no runtime bump needed.** Wider catalog: `qwen3-embedding-4b` and `decider-4b` from 0.17.4, `embeddinggemma-2`
+(text ≤ 8,192 tokens, pictures and audio in one vector space) and `wemm-embedding-4b` from 0.18.3.
+
+Embedding contract on that lane: `POST /v1/embeddings`, `model: "qwen3-embedding-0.6b"`, `input` a list of **texts**
+(not token ids), 1024 unit-length floats back, the Qwen instruct prefix goes inside the string
+(`Instruct: …\nQuery:…`), `base64` accepted, and LangChain's `OpenAIEmbeddings` needs
+`check_embedding_ctx_length=False`.
+
+Four host prerequisites, each refused **by name** in the serve script and mirrored in `deploy_llm_dragoon` — a
+precondition that surfaces as an engine crash-loop is a gate that was never written. All four are satisfied on this
+box as of 2026-10-19; the endpoint still runs with the lane **off** until that day's mount fix merges, and the first
+armed boot's evidence lands here with it:
+
+1. `--device /dev/accel/accel0` **and** a node the container's namespace can open. `/dev/accel/accel0` is
+   `root:render 0660` and a rootless namespace maps exactly one uid/gid, so the engine's own first words are
+   *"this process cannot open it (crw-rw---- nobody:nogroup)"*. `--group-add keep-groups` — the vendor's advice and
+   the ComfyUI pattern for `/dev/kfd` — is **dead in this shape**: measured 2026-10-19 from a `dank` shell already
+   in `render`, with and without the flag the node stayed `nobody:nogroup` and the open was refused; an unmapped
+   gid cannot be granted across a namespace that does not map it. The door is the udev mode
+   (`dankclaw/udev/98-halogen-npu-access.rules`, installed and re-triggered by the deployer, `0666` like the GPU
+   compute nodes beside it); the serve script refuses any node that is not other-accessible, so the fault cannot
+   return as a crash-loop.
+2. The host's XRT reachable inside: there is **no `/opt/xilinx/xrt`** here — distro packages put the three files the
+   container needs (`libxrt_coreutil.so.2`, `libxrt_core.so.2`, `libxrt_driver_xdna.so.2`) in
+   `/usr/lib/x86_64-linux-gnu`, where all three exist.
+3. **The GPU fabric clock held at its top level, or the engine refuses to start.** GPU and NPU work share the die:
+   while `pp_dpm_fclk` is changing speed, concurrent GPU work can hang the machine and corrupt NPU results. The
+   engine holds the clock itself only when it runs as root with `/sys` mounted; `frank-dragoon` is a **rootless**
+   `podman run` under `User=dank`, so the path is the vendor's root host unit (`deploy/host/halogen-fabric-clock`) —
+   which is exactly the `pp_dpm_fclk` level-7 pin deferred in [[dankclaw-iommu-translation-off]] with the words "it
+   goes in when an NPU endpoint actually exists". Held: about a watt. Unheld: the hang. The deployer installs and
+   enables that unit whenever the lane is named, and `halogen-fabric-clock status` reports `held (manual)` here as of
+   2026-10-19; the serve script re-reads the same two sysfs files at every start and refuses by name if the top level
+   is not the starred one, because a hold done by hand is a countdown to the next reboot.
+4. The programs are staged under `$FRANK_DRAGOON_NPU_DIR`, which **must sit inside the payload dir**
+   (`/home/dank/models/halogen-v2-abliterated/npu`): the payload's read-only mount is the container's only handle on
+   `/models`. A nested bind at `/models/npu` cannot work — the image ships no `/models`, so runc has to `mkdir` the
+   mountpoint through a read-only parent and dies at container init (measured 2026-10-19: 52 crash-loop restarts with
+   chat down before the mount shape was fixed). `HALOGEN_NPU_DIR` is no escape; the shipped entrypoint rejects it by
+   name ("our NPU models live under `/models/npu/<id>/`"). Nothing downloads at boot — `HALOGEN_DOWNLOAD` stays
+   unset, so the container opens no outbound connection; `scripts/download-frank-dragoon-npu.sh` pins every file by
+   size and sha256 against the catalog and the payload mount carries the tree in.
+
+Price: the programs and their weights sit in host RAM beside the 62.9 GiB of locked weights ("a few GB in all" for
+the default set; ~1.1 GiB for `embeddinggemma-2`), and **the Flash model decodes slower while the NPU works** — same
+memory bus, same power budget. Under this page's RAM law the question is pool versus n-gram table, so read the boot
+ledger after the first NPU boot instead of modelling it. If the lane is opened, prefer **0.18.8 or newer**: that
+release budgets NPU memory before asking for it, fixing kernel errors from several NPU models under a concurrent mix
+**on the stock kernel driver** — the driver this box runs.

Frank	fcf94562d1	feat(frank-dragoon): open the NPU node the way rootless can actually reach it The armed boot reached the engine and died in its own preflight: halogen npu: /dev/accel/accel0 is here, but this process cannot open it (crw-rw---- nobody:nogroup). The node is root:render 0660 and a rootless container maps exactly one uid/gid, so `render` is unmapped inside it and `--group-add keep-groups` — the vendor's advice, and the ComfyUI pattern for /dev/kfd — cannot grant a group the namespace does not map. Measured 2026-10-19 from a `dank` shell already in `render`: without the flag denied, with the flag denied, with the udev mode 0666 the open succeeds (OPEN_OK). Same wall 99-comfyui-gpu-access.rules already solved for the GPU compute nodes, so the accel node gets its counterpart: dankclaw/udev/98-halogen-npu-access.rules — KERNEL=="accel[0-9]*", SUBSYSTEM=="accel", MODE="0666" The deployer installs the rule, reloads rules, re-triggers the node and only then checks the mode; the serve script refuses any node that is not other-writable, naming the rule, so this cannot return as a crash loop (189 restarts while chat was down is the failure mode being closed). Both checks read the permission bit directly: `[ -o FILE ]` is not "other-writable" — it means "exists" and `-o` doubles as the OR operator inside test, which is why the first cut of the gate refused everything. Dragoon seam: 33 -> 35 tests. The fixture node is 0666 like the installed one, a 0660 node is refused with the rule named and nothing rendered, and the rule file's shape plus the deployer's install/trigger are asserted.	2026-10-19 22:35:06 -07:00
Frank	3ef711f146	fix(deploy): the dragoon gate reads the deployer's own payload-dir twin The containment gate added in #44 parsed scripts/frank-dragoon.env through a $CHECKOUT variable that does not exist in deploy-remote.sh, so the very next deploy died at `set -u` before it touched the unit: ./scripts/deploy-remote.sh: line 1445: CHECKOUT: unbound variable deploy-remote.sh runs from the checkout root and every other path in that block is a parity-twin default (LLM_DRAGOON_CKPT/_VISION/_TOK_DIR), so the payload dir gets the same treatment: LLM_DRAGOON_MODEL_DIR, defaulted to the deployed path, compared directly. The seam now asserts that twin against the env file next to the NPU twins it already checks, and the containment comparison itself is verified both ways (inside accepted; the old outside path and a shared-prefix sibling both refused).	2026-10-19 21:48:47 -07:00

Frank	bda011d26f	docs(vault): the NPU lane's one door into the container, and the pin that landed frank-dragoon's lane section: the staging dir must live inside the payload dir (the image ships no /models, so a nested :ro bind has no mountpoint to land on), the entrypoint's rejection of HALOGEN_NPU_DIR, and the fabric-clock paragraph corrected — the vendor's root host unit is installed and reports `held (manual)` as of today, so "nothing is held" is retired along with the hand-write it replaced. dankclaw-iommu-translation-off: the deferred `pp_dpm_fclk` pin is no longer deferred; the fact is owned by [[frank-dragoon]] and this page links it.	2026-10-19 21:43:36 -07:00
Frank	b19f1c49d6	fix(frank-dragoon): stage the NPU lane inside the payload mount The lane's first boot died at container init, not at the engine: runc create failed: ... create mountpoint for /models/npu mount: mkdirat .../merged/models/npu: read-only file system The image ships no /models, and the serve script binds the payload dir there read-only, so a nested `-v $NPU_DIR:/models/npu:ro` had to create its own mountpoint underneath a read-only parent — impossible. The engine's own entrypoint confirms the container path is fixed: it rejects HALOGEN_NPU_DIR outright ("our NPU models live under /models/npu/<id>/"). Fix is the mount shape, not the engine: FRANK_DRAGOON_NPU_DIR now lives inside FRANK_DRAGOON_MODEL_DIR, so the payload's single read-only mount puts the files at /models/npu/<id>/ by itself and the nested bind is gone. Verified on the running container: after the move, `podman exec frank-dragoon-halogen ls /models/npu/qwen3-embedding-0.6b` answers with the staged tree while the lane is still armed off. Both gates refuse the old shape by name (serve + deployer parity) so a future payload swap that moves the model dir cannot reintroduce a crash that lands after the deployer has already stopped the running unit.	2026-10-19 21:42:31 -07:00

Frankandomp	7f65cf0252	docs(vault): the pasta endpoint has no address an app container can use The 2026-10-19 legs table blamed the frank-dragoon refusal on a root/rootless netavark rule-set split. It is not that: the container is rootless (the root unit's User=dank runs podman run), it is on pasta, and pasta installs no DNAT for rootless-bridge traffic while refusing a second network outright. The gateway alias does reach it (200) and is link-local, which is the same dead end the Open Notebook URL guard hit. Measured with the move onto the bridge now in the deployer, including the /proc/net/tcp line that shows 8730 is loopback-bound and so stays private after the move.

Frankandomp	346e1d22f4	feat(frank-dragoon): put the endpoint on the app bridge so app containers can name it An endpoint on podman's rootless default (pasta) has no address another container can use, measured on 2026-10-19 from inside open-notebook: - 192.168.0.143:7770 connection refused (pasta forwards the published port in the host netns; no netavark DNAT exists for traffic arriving from a rootless bridge) - host.containers.internal:7770 200, but the alias resolves to 169.254.1.2 — link-local, which open-notebook's URL guard refuses to store - frank-dragoon-halogen:8731 name unknown: different netns - --network pasta --network dankclaw_default "cannot set multiple networks without bridge network mode" — pasta cannot be added to So reaching the NPU endpoints from an app container means moving the container onto dankclaw_default (FRANK_DRAGOON_NETWORK; empty keeps today's shape). This is not an exposure change: the engine's unauthenticated token port binds the container's own loopback (/proc/net/tcp: 127.0.0.1:8730 against 0.0.0.0:8731), so only the API port becomes name-resolvable — the same trust the published 7770 already carries on the LAN. The deployer refuses a network that does not exist rather than starting a unit that restart-loops on it. Co-Authored-By: omp <omp@dankclaw>	2026-10-19 21:27:07 -07:00
Frankandomp	53ef121180	feat(frank-dragoon): run the XDNA2 NPU lane beside the flash model halogen-flash-server already ships an NPU path on the pin we run: for each model named in HALOGEN_NPU_MODELS it loads the vendor's precompiled AIE programs (XDNA2 executes only AIE-compiled graphs) and answers them on /v1/embeddings inside the SAME container behind port 7770. That gives the fleet an in-house embedding endpoint without touching the iGPU trunk. The lane is opt-in and one line wide: HALOGEN_NPU_MODELS blank is the pre-lane endpoint byte for byte (no device, no mounts, no engine env). The three host preconditions the vendor names are gated in the serve script and mirrored in the deployer (the 2026-10-01 twin law), each refused by name: - the staged model files. /models is read-only and HALOGEN_DOWNLOAD stays unset so the container opens no outbound connection at boot, so scripts/download-frank-dragoon-npu.sh stages them from the pinned revision with the catalog's own byte counts and sha256s (the engine re-checks both at boot); - the distro XRT's libxrt_coreutil/libxrt_core/libxrt_driver_xdna, each mounted twice — where the image looks for XRT and at its own path — because those libraries find each other where they were installed and an /opt/xilinx/xrt of symlinks dangles inside the container; - the GPU fabric clock HELD. On Strix Halo the iGPU and the NPU co-running hang the machine (and corrupt NPU results) while FCLK changes speed, and halogen refuses to start in that state; it cannot read host sysfs from inside, so the hold is proven host-side. dankclaw/host/ carries the vendor's halogen-fabric-clock{,.service} verbatim at tag v0.16.2 (sha256 a3a4f7f4e0142e71… / 5f9f1cc4c85a1c02…); the deployer installs, enables and gates it only while the lane is named, and releases the clock plus drops the boot hook when it is not. After health, the deployer's lane gate is a real embedding through /v1/embeddings — a 200 on /health proves nothing about the NPU programs. Planner: dankclaw/host/halogen-fabric-clock* re-dispatches frank-dragoon (the deployer installs it); dankclaw/host/grub and the fetch script plan nothing. Seam: 11 new tests — the off arm really renders nothing lane-specific, the on arm renders the device/mounts/env, every missing precondition refuses by name, the deployer twins and the host unit shape are pinned.

Frank	6215f1a6c8	docs(vault): halogen has an NPU lane on the pin we already run, and it is greedy-only - frank-dragoon: measured the response_format contract. json_schema and json_object answer schema-valid JSON at temperature 0 and draw a 400 at any sampled temperature, and because the sampler default is server-side an absent temperature is sampled. The page claimed "response_format is unsupported", which sends the next agent past a working feature. - frank-dragoon: new "The NPU lane" section. The pinned 0.16.2 image already ships the five-program AIE catalog including qwen3-embedding-0.6b, so /v1/embeddings is one env var plus the accel device, the distro-XRT mount and the fabric-clock hold; embeddinggemma-2 needs 0.18.3+, the stock-kernel-driver memory-budget fix 0.18.8+. Host census recorded: no /opt/xilinx/xrt, distro XRT 1:2.21.75 with libxrt_driver_xdna, clocks unheld. - Open Notebook: scriptwriter probe verdict — greedy-only, and open-notebook's model record is {credential, name, provider, type} with no per-row config, so it cannot ask for greedy; frank-archon stays the writer. The embedding gap now has a named door instead of "build a new llama.cpp slot". - Frank TTS: "the NPU is not a door at all" was too broad. It is not a door for the TTS family; halogen's precompiled catalog is a door on the same device. - System Specs: NPU runtime row corrected to the distro XRT actually installed, and the stale "frank-zealot serves 27B" line retired in favour of [[frank-zealot]] as sole owner.

Frank	69739237c8	docs(open-notebook): record the deployed shape and what the first render proved The page described an undeployed service whose scriptwriter was going to be frank-zealot. Both halves are now false, and the reason is worth more than the correction. - Status, ports, coordinates: deployed 2026-10-19, guarded vhost, API published on loopback only. The first episode is the proof: 747 s of speech in 301 s of wall clock (2.5x real time, knobs at 1), download route 200 with the bearer and 401 without. - New section for the guard chain: provider-before-route, one upstream because the image rewrites /api/* itself, and the API_URL law — autodetect appends :5055, which is seerr's port on this host, so an unset API_URL yields a UI that loads and an app that cannot call itself. - Provisioned records table (credentials, model rows, dank-duo, dank-daily) and the two contract traps measured on the live API: generate takes profile NAMES, and the fleet has no /v1/embeddings, so every note save fails its embed_note command while renders from content work fine. - Why frank-archon writes the scripts: frank-zealot is reachable from this netns only at 169.254.1.2, and open-notebook's URL guard refuses to store a link-local base URL with no override. Census lands on [[Container Network Namespaces]], which also gains the root-vs-rootless publish rule — a root-published port is invisible to a rootless container, so "publish the port" was the wrong remedy as written there. - Frank TTS: the request's model field is ignored; only voice selects a pack. Tests: ./tests/run.sh, 455 passed.	2026-10-19 16:22:38 -07:00
Frank	e5580abb6f	feat(open-notebook): put the podcast generator behind the guard chain The service came up internal-only: UI on the LAN at 8502, API at 5056, both published on every interface, with only its own shared password in front. That put the episode library outside the fleet's auth chain and one port scan away from anything on the network. - Caddy: guarded vhost notebook.franksdank.cloud (Anubis -> Authentik; provider notebook-proxy, internal_host caddy:8017) plus the post-auth route to the published UI port. One upstream is enough, because the image's own Next.js layer rewrites /api/* to the FastAPI beside it — so the API needs no outward face at all, and 5056 moves to loopback, where only the deployer's health gate dials it. - scripts/open-notebook.env: API_URL and CORS_ORIGINS become the single guarded origin. Left to itself the app auto-detects <host>:5055, the port seerr holds on this host; a LAN-origin API_URL would also take the browser around the guard chain, where its authenticated session does not ride. - addn-hosts: the LAN A record. The homepage card goes live and links the vhost. - Seam: the API origin is derived from whatever the Caddyfile routes to 8502, so renaming the vhost moves the test instead of leaving it blessing a stale name, and a new test proves the vhost hands the WHOLE request to Anubis.	2026-10-19 16:13:53 -07:00
dank	ee6d8610b3	Merge pull request 'fix(open-notebook): the database probe has to be exec-form JSON' (#40 ) from feat/open-notebook-portal into main	2026-10-19 16:07:53 -07:00
Frank	933420fd29	fix(open-notebook): the database probe has to be exec-form JSON podman wraps a bare HealthCmd as CMD-SHELL (measured on Dankclaw's podman 5.7: --health-cmd "/surreal is-ready" stores {"Test":["CMD-SHELL","/surreal is-ready"]}), and the pinned SurrealDB v2 image is distroless — no /bin/sh, not even `ls`. So the probe could never run: every 30 s interval exited 1 in ~30 ms with empty output while the database was listening and answering, and open-notebook's first deploy died at the gate ("did not become healthy in 90s"). The hand-check `podman exec … /surreal is-ready` printed OK, which is why the old comment believed the probe worked. The JSON array survives the Quadlet generator (--health-cmd "[\"/surreal\",\"is-ready\"]") and stores ["CMD","/surreal","is-ready"], which execs directly: a throwaway instance of the pinned digest went healthy on that form. The seam is re-pinned to the shell-free contract; the old assertion forbade quotes in any HealthCmd, which is what pinned the broken shape.	2026-10-19 16:07:28 -07:00
