docs(pi-hole): FTL can boot with the record file mounted and serve none of it

The 2026-10-19 reboot left every franksdank.cloud name NXDOMAIN for LAN clients while external names kept answering from cache; the file was mounted and readable and dns.hosts was intact, and 'pihole restartdns reload' restored every name in seconds. Mechanism not established. Instrument and remedy now on the owner page, plus a failure-mode row for the FTL rate-limit case seen beside it (10.0.2.x = a pasta container's forwarder).

-**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.
+**Embeddings run on the XDNA2 lane — provisioned 2026-10-19.** `qwen3-embedding-0.6b` answers `/v1/embeddings` at `http://frank-dragoon-halogen:8731/v1`, the flash container's own bridge address; a container name on `dankclaw_default` resolves to `10.89.1.39`, plain RFC1918, so it clears the URL guard that ruled out `host.containers.internal` above. The lane's shape (one program, the token ceiling, what it costs the Flash model) is owned by [[frank-dragoon]]; the two shapes that bite on the app side are open-notebook's own:
+
+- **`PUT /api/models/defaults` stores the record ID, not the name.** `"default_embedding_model": "qwen3-embedding-0.6b"` is accepted and echoed back, and then every embed dies in the worker with `Model with ID qwen3-embedding-0.6b not found`. The value has to be the row's `model:…` id — the other defaults in that same object are ids, so mirror them.
+- **`POST /api/embed` answers 500 while succeeding.** Upstream's `EmbedResponse.command_id` declares `str` and the worker hands it a `RecordID`, so FastAPI raises on serialization *after* the vector is written. The truth is the worker line `Successfully embedded note … in 0.19s`, never the HTTP code. Saving a note (`POST /api/notes`) submits `embed_note` by itself, so that route is only needed to backfill old rows.
+
+Proof from the app's own paths, 2026-10-19: `POST /api/models/{id}/test` → `Embedding dimensions: 1024`; two notes with nothing in common, then `POST /api/search` with `type: "vector"` (the enum is `text` or `vector`; the score field is `similarity`) — "a yellow waterbird beside a glowing beacon tower" put the grebe note at **0.659** and the boiler note at 0.292, and "quarterly depreciation schedule for industrial boilers" inverted it to **0.906** / 0.318. Embed cost 0.19–0.43 s per note. Semantic search, source ingestion and notebook-context questions are live; podcast generation never needed any of it.
 
 **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`:
