docs(voice-packs): runbook, index link, and the log entry

The page a new operator needs: what the three required files are and who
reads each one, how a pack is built (with the extractor's usage text
verbatim, because the flags are not guessable and there is no -o), the
10-second gate and where it fires twice, how to add a fourth voice
including the warm hook that registers a pack without restarting the
engine, and the engine-bump procedure for when the artifact sizes move.
Plus the host census as of 2026-10-18 — the trial packs carry no
artifacts and their manifest is the trial's own schema, so the builder's
first real run is a --force migration — and the three gaps left open on
purpose: no curated ICL transcript, no 16 kHz variant, no loudness pass.

+# IMAGE. `surrealdb/surrealdb:v2` pinned by manifest-list digest, resolved from
+# the registry on 2026-10-18 (that digest is SurrealDB 2.7.0, image built
+# 2026-09-23; `v2` itself is a MOVING tag, so the digest — not the tag — is what
+# makes this reproducible). Upstream open-notebook's own compose file pins the
+# same `v2` tag, and its Dockerfile copies /surreal out of the same image for
+# the retired single-container variant, so v2 is the version this app is built
+# against. Pull=never + the documented pull step (docs: [[Open Notebook]]):
+#
+#   podman pull docker.io/surrealdb/surrealdb:v2@sha256:e5d7387e3727bbe2f7cd6d869e48cd34777272258572ead37c9656b25f745723
+#
+# NO PUBLISHED PORT. 8000 is deliberately not published: the app reaches it by
+# name on systemd-open-notebook, and a published 8000 would put the RPC with
+# the root credentials on every interface (upstream publishes 127.0.0.1:8000
+# "purely for local debugging" — a `podman exec` probe is enough here). The
+# binary binds 0.0.0.0:8000 INSIDE its own namespace via the image's
+# SURREAL_BIND env; without that image default it would bind loopback only and
+# the app could never connect, so no --bind flag belongs here.
+#
+# CREDENTIALS, AND WHY THEY ARE NOT IN THE COMMAND LINE. The `surreal start`
+# CLI reads its options from the environment (`--username` is [env:
+# SURREAL_USER=], `--password` is [env: SURREAL_PASS=] — verified against the
+# pinned image's own `start --help`), so the credentials arrive through the two
+# EnvironmentFile lines and the argv stays clean. Passing `--pass` instead —
+# what upstream's compose does — would put the database password in
+# /proc/<pid>/cmdline, readable by any `ps` on the host. Note the two
+# spellings: the DATABASE reads SURREAL_PASS, the APP reads SURREAL_PASSWORD,
+# and scripts/open-notebook.env declares both because they must hold the same
+# value; the deployer writes that pair when it seeds the host secret file.
+#
+# NO USER= OVERRIDE. The image runs as uid 65532 (Chainguard glibc-dynamic
+# base). With a NAMED volume that works unmodified: podman creates the volume's
+# backing directory owned by the container's user (measured with this digest —
+# the host directory lands on the mapped subuid and the store starts clean),
+# which is exactly why upstream's `user: root` line is not repeated here: that
+# line is commented in upstream as being "required for bind mounts", and this
+# unit has none. The consequence is that the DB files are NOT readable by dank
+# without `podman unshare` — accepted for a datastore nobody edits by hand;
+# episode AUDIO is a host directory for the opposite reason (see the app unit).
+#
+# HEALTH. The base image is distroless: no shell, no curl, no wget, so no
+# CMD-SHELL probe and no wget/curl probe is possible here (same class of unit
+# as loki, whose probe had to move into the image). SurrealDB ships its own
+# probe instead — `surreal is-ready` connects to ws://localhost:8000 by default
+# and needs no credentials — verified against this digest: it prints `OK` and
+# exits 0 while the server is up. Argument-only HealthCmd, like every unit on
+# this host, because the quadlet generator splits it on spaces.

+#
+# NETWORKS, in this order on purpose. The generated run line keeps file order,
+# so the DEFAULT ROUTE rides dankclaw_default: that is the network where this
+# host has measured that a bridge container can reach a host-namespace
+# listener through the gateway name (the Prometheus scrape of frank-zealot is
+# the proof — see [[Container Network Namespaces]]), and frank-tts lives there
+# too, so the TTS credential can be `http://frank-tts:7772/v1`. The private
+# systemd-open-notebook bridge is second and carries only the database; its
+# traffic is on-link, so losing the default route costs it nothing.
+#
+# PUBLISHED PORTS, and the 5055 collision. Upstream publishes 8502 and 5055,
+# and 5055 is exactly the port seerr already holds on this host
+# (`PublishPort=127.0.0.1:5055:5055`; `ss -ltn` on Dankclaw 2026-10-18 shows
+# 127.0.0.1:5055 taken). So the API leaves the container on host port 5056.
+# That forces one setting: the frontend auto-detects the API as
+# `<host-you-opened>:5055`, so API_URL in scripts/open-notebook.env must name
+# the remapped port explicitly, or the UI loads and every call fails. Both
+# ports are published on all interfaces because the consumer is a browser on
+# the LAN — the fleet's browser-facing services (open-webui, comfyui, gitea)
+# bind the same way, while loopback-only is reserved for services whose user
+# path is the guard chain. This service has NO vhost and no Caddy route: it is
+# internal-only until it is guarded, and its own password
+# (OPEN_NOTEBOOK_PASSWORD) is what stands in front of it. That password is not
+# decoration: with it unset the API answers everyone on the LAN, including the
+# unauthenticated episode-audio download.
+#
+# VOLUMES. `/app/data` is a named volume: uploads, the LangGraph SQLite
+# checkpoints and the extraction caches the image keeps under it
+# (UV_CACHE_DIR, HF_HOME) are app state nobody browses. The ONE exception is
+# finished audio, which is bind-mounted out of the container at
+# /home/dank/media/podcasts. That mount is interim and reversible: episode
+# destination is an open human-only decision (Gitea issue #7, label
+# `human-only` — agents must not work it), and until it lands, episodes are
+# ordinary files on the host. DATA_FOLDER is hard-coded `./data` in the app
+# (WORKDIR /app) and the DB stores audio paths RELATIVE to data/podcasts, so
+# covering that one subdirectory is enough and removing the line changes
+# nothing else. The image declares no USER, so the app runs as container root,
+# which in this host's rootless mapping (0 -> 1000, measured on this host —
+# see [[Seerr]]) writes those episode files as dank.
+#
+# HEALTH. `GET /health` on the API returns {"status":"healthy"} and is in the
+# password middleware's excluded-path list, so the probe stays honest after the
+# password is set (both read from api/main.py upstream). The image installs
+# curl and ffmpeg in the runtime layer, so the probe needs no shell — kept
+# argument-only for the generator's space-splitting. Note what this probe does
+# NOT prove: the route returns a static body, so it says the API serves, not
+# that the database answers. The DB has its own probe in its unit, and the
+# worker's failure to reach the database shows up as failed jobs, not as an
+# unhealthy container.

+# build-voice-pack.sh — turn a SOURCE recording plus a CROP OFFSET into a
+# deployable frank-tts voice pack: the reference WAV, the engine's own speaker
+# artifacts made from it, and manifest.json provenance.
+#
+# THE PACK. $PACKS_DIR/<voice>/ carries the three members the pack law in
+# scripts/frank-tts.env names:
+#
+#   reference.wav    the crop: 24 kHz mono PCM (pcm_s16le), 18-25 s of clean
+#                    single-speaker audio. This is what makes a voice NAME real
+#                    (dankclaw/voiceservice/app.py lists and resolves exactly
+#                    this file), so it is written LAST, once everything else in
+#                    the pack has been verified.
+#   reference.spk    the engine's x-vector: enc_dim 2048 f32 = 8,192 B.
+#   reference.rvq    the engine's RVQ code stream: 16 codebooks x 11 bits = 22 B
+#                    per 12.5 Hz frame = 22 * floor(samples / 1920).
+#   manifest.json    provenance: source path and sha256, crop start/end, sample
+#                    rate, duration, the tool + engine commit that made the
+#                    artifacts, and the voice name.
+#
+# Both artifacts come from the pinned engine build's speaker extractor — the
+# `qwen-codec` tool of qwentts.cpp at VOICE_PACK_ENGINE_COMMIT — run on the pack's
+# own WAV, and the extractor names them by swapping the input's extension, so
+# they land beside reference.wav with nothing to rename. Required, never a
+# replacement for the WAV: a voice another runtime cannot reuse is not saved.
+#
+# THE 10-SECOND GATE — THE REASON THIS SCRIPT EXISTS. Project-wide source-material
+# invariant: the first 10 s of any sample file used to generate voices is
+# forbidden material. An offset that starts inside that region is refused with a
+# nonzero exit BEFORE anything is created — no pack dir, no WAV, no artifact — and
+# the same gate is asserted a second time from the manifest that was just written
+# (plus the recorded sha256 against the source it claims). A pack carrying a
+# forbidden crop therefore cannot survive a build.
+#
+# THE ARTIFACT SIZES ARE CHECKED, NOT ASSUMED. They are a property of the codec
+# config inside the GGUF, so an engine bump that changes enc_dim or the codebook
+# count fails the build instead of shipping a pack the engine will reject at
+# synthesis time. Note the interaction with the WAV window: an 18.0 s crop is a
+# legal reference.wav but only 22 * 225 = 4,950 B of .rvq, under the recorded
+# 5,456 B floor, so the effective crop window is 19.84-25 s. That is a real
+# constraint and the builder says so up front rather than failing after a build;
+# serverAppConfigs-docs/Dankclaw/Voice Packs.md covers what to do on an engine bump.
+#
+# WHERE IT RUNS: the host that holds the engine build (Dankclaw). The extractor is
+# a CPU ggml binary — no GPU, no container, no fleet endpoint, no network. ffmpeg
+# does the crop; every spawned process runs `nice -n 19` so a pack build never
+# competes with the text endpoints on that box.
+#
+# IT NEVER DELETES. An existing pack is refused unless --force, and --force moves
+# the whole old directory aside into $PACKS_DIR/.AGENTTRASH/<voice>-<UTC>/ rather
+# than overwriting or unlinking a single byte.

+# generator on Dankclaw (UI host port **8502**, API host port **5056**). Read by
+# BOTH Quadlet units (dankclaw/open-notebook/quadlet/) as the FIRST
+# EnvironmentFile= line, which is why every path and host name below is the
+# value the CONTAINER must see.
+#
+# TWO FILES, ONE ORDER. This file is tracked; it holds knobs, not credentials.
+# The three secret keys below are declared EMPTY on purpose — the `scripts/*.env`
+# gitignore exception exists for "paths and numbers, never credentials" — and the
+# real values live in the host file the deployer seeds at
+# /home/dank/Containers/open-notebook/env (mode 600, seeded from dankclaw/.env,
+# the same convention grafana/marreta/pihole follow). Both files are handed to
+# podman in EnvironmentFile= order and the LAST one wins (verified against the
+# generated run line), so the host file overrides these blanks. Do not reorder
+# the two lines.
+#
+# WHY THE DEPLOYER REFUSES TO START THESE UNITS WITHOUT THE SECRET FILE. An empty
+# OPEN_NOTEBOOK_PASSWORD is not "unconfigured", it is **authentication off**, and
+# the episode-audio download is one of the routes the API serves without a
+# session; an empty SURREAL_PASS lets the database come up with different root
+# credentials than the app will present; an empty OPEN_NOTEBOOK_ENCRYPTION_KEY
+# means no provider credential can be saved at all. So the guard is in
+# deploy-remote.sh (seed_open_notebook_env), not in the app's opinion.
+#
+# THE CPU-SHUTDOWN GUARD (the two knobs that matter most on this box). Defaults
+# are TTS_BATCH_SIZE=5 and OPEN_NOTEBOOK_WORKER_MAX_TASKS=5 — five parallel
+# synthesis requests from five parallel jobs. frank-tts answers each request by
+# spawning its own engine process (~8 GiB resident, 8 threads, measured in the
+# frank-tts CPU trial of 2026-10-18), so the defaults mean ~40 GiB and forty
+# threads aimed at a machine that also serves frank-dragoon and frank-zealot and
+# whose TTS engine runs on the SAME CPU. Both numbers are 1 here: one episode at
+# a time, one voice line synthesized at a time. That is a throughput choice, not
+# a correctness one — a podcast is a background job — and it is the difference
+# between a slow render and a box that stops answering the text endpoints
+# mid-sentence. Raise them only with a TTS engine that batches internally.
+#
+# THE TTS CLOCK. ESPERANTO_TTS_TIMEOUT is the worker's patience per DIALOGUE
+# LINE, not per episode: one episode is dozens of POSTs to /v1/audio/speech
+# (the app synthesises each speaker turn separately and concatenates the clips
+# with ffmpeg afterwards), and a CPU engine takes single-digit seconds for a
+# line, with the tail of a long turn well past the 300 s default. 660 sits one
+# round-trip OUTSIDE SHIM_TIMEOUT=600 in scripts/frank-tts.env — the shim's own
+# per-request ceiling — so a frank-tts give-up arrives as frank-tts's error and
+# not as open-notebook abandoning a synthesis still in flight. An abandoned
+# request does not cancel the engine process; it just leaves the episode stuck in
+# "generating" while the audio arrives.
+#
+# THE SCRIPTWRITER. ESPERANTO_LLM_TIMEOUT is the app's own default (180 s), kept
+# visible beside the TTS number because both belong to one podcast run: the
+# outline call and the transcript call are the slow text work, and frank-zealot
+# answers them well inside 180. Provider choice is made in the UI, not here —
+# see [[Open Notebook]] for the one-time credential provisioning — and it is
+# frank-zealot on purpose: script writing asks for a JSON-schema response, which
+# the OpenAI-compatible llama.cpp endpoint is known to serve, while halogen's
+# structured-output behaviour on frank-dragoon is UNVERIFIED. halogen remains
+# the unproven alternative, not the fallback.
+#
+# THE DATABASE COORDINATES. SURREAL_URL addresses the sibling container BY NAME
+# on systemd-open-notebook (container DNS is scoped to the owning network, so
+# this is the only form that works). NAMESPACE/DATABASE/USER are plain names.
+# SURREAL_PASSWORD and SURREAL_PASS are ONE value under two spellings: the app
+# reads SURREAL_PASSWORD, the `surreal` CLI reads SURREAL_PASS. Keep them equal;

+# voice-packs.env — tunables for the **frank-tts voice packs**: the three

+# engine facts that turn a crop into a pack. Read by
+# `scripts/build-voice-pack.sh`, which is the only thing that consumes this

+# the interface (see scripts/frank-tts.env for what the shim resolves).
+#
+# WHAT IS TRACKED HERE AND WHAT IS NOT. Paths and numbers, never credentials,
+# which is the same rule the other `scripts/*.env` files follow. The pack
+# DIRECTORIES are host state under $VOICE_PACK_DIR and stay out of the repo; the
+# crops that produce them are exactly the kind of decision worth a diff, so the
+# offsets live here. If a crop changes, change it here and rebuild with
+# --force — the manifest inside the pack records what was actually cut.
+#
+# THE OFFSETS ARE NOT ARBITRARY. Two rules pick them:
+#   1. The source-material invariant: seconds 0-10 of any sample file are
+#      forbidden voice material. The builder refuses a crop that starts inside
+#      that region and asserts the same thing again from the manifest it just
+#      wrote, so the values below are checked, not trusted.
+#   2. Speech density: the trial cut these from a silencedetect scan of the
+#      source (noise -35 dB, 0.6 s) and took the longest run of continuous
+#      speech at or past the scan window — a reference that starts mid-word or
+#      contains a page-turn of silence clones the artefacts, not the voice.
+#      serverAppConfigs-docs/Dankclaw/Voice Packs.md carries the recipe.
+#
+# WHY THE SHA256 LINES EXIST. A crop offset is a statement about one exact
+# file: 98.739 s into a re-encode of the same audiobook is a different sentence
+# and therefore a different voice. The builder hashes the source, compares it
+# with the pinned digest when one is set, and writes the digest into the pack's
+# manifest — so a pack can always be traced back to the bytes it was cut from.
+# The three values below are the trial's digests (2026-10-18), verified against
+# the files on disk.
+#
+# THE ENGINE BLOCK IS A PIN, NOT A DEFAULT. The speaker artifacts come from
+# `qwen-codec` in the qwentts.cpp tree at $VOICE_PACK_ENGINE_COMMIT: it takes a
+# 24 kHz WAV, writes the RVQ code stream next to it with the extension swapped,
+# and with --talker also runs that talker's speaker encoder to write the
+# x-vector .spk. The talker has to be a **Base** build — the customvoice and
+# voicedesign GGUFs carry no speaker encoder and the extractor says so. The
+# sizes the builder then verifies (8,192 B of .spk, 5,456-6,864 B of .rvq) are
+# derived from the codec config in the GGUF, so an engine bump that changes them
+# fails the build on purpose; see [[Voice Packs]] for the bump procedure.
+#
+# HOST PATHS, NOT CONTAINER PATHS. This runs on the host that holds the engine
+# build (Dankclaw), outside any container, with no GPU and no fleet endpoint.
+# The model paths below are where scripts/download-frank-tts-engine-qwentts.sh

+# Open Notebook
+
+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. In the fleet it is the consumer that closes the loop Frank's audio stack was built for — the script is written by **frank-zealot**, the voices are rendered by **frank-tts**, and nothing leaves the LAN.
+
+**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`. Deploying it is a deliberate next step, not a pending one.
+
+**Host:** Dankclaw (rootless Podman, user `dank`) — **Ports:** 8502 UI and 5056 API, published on the LAN, **no vhost and no Caddy route** — **Deployer:** `open-notebook` (one service, two units) — **Docs:** https://github.com/lfnovo/open-notebook
+
+## Facts (verified 2026-10-18 against the pinned images, upstream source, and the live host)
+
+| Item | Value |
+|------|-------|
+| App image | `docker.io/lfnovo/open_notebook:v1-latest@sha256:54b2025a4a4853c188f74b9b8246eca8c5480e5dd1babfa92db1038ff2f30212` (`open-notebook.container:79`) — the tag upstream's own `docker-compose.yml:27` pins for the multi-container shape. `v1-latest` is a moving tag, so the manifest-list digest (resolved from the registry 2026-10-18) is what makes this reproducible |
+| Database image | `docker.io/surrealdb/surrealdb:v2@sha256:e5d7387e3727bbe2f7cd6d869e48cd34777272258572ead37c9656b25f745723` (`open-notebook-surrealdb.container:66`) — that digest is **SurrealDB 2.7.0** (image built 2026-09-23; measured by running the digest: `surreal version`) |
+| Do NOT use | the `-single` tags (`v1-latest-single`). That variant bundles SurrealDB inside the app image and is deprecated upstream; here it would give the host a second, hidden database |
+| Ports | container 8502 (Next.js UI) + 5055 (FastAPI API) → published `0.0.0.0:8502:8502` and `0.0.0.0:5056:5055` (`open-notebook.container:83-84`). **Host 5055 is taken**: seerr publishes `127.0.0.1:5055` (`dankclaw/seerr/quadlet/seerr.container`, and `ss -ltn` on Dankclaw shows `127.0.0.1:5055` live, 2026-10-18). The API therefore leaves on 5056, which is what forces `API_URL` (below) |
+| Database port | 8000 inside its own namespace, **never published** (`open-notebook-surrealdb.container` has no `PublishPort`). Upstream publishes `127.0.0.1:8000` for debugging (`docker-compose.yml:18`); this unit does not, and the seam asserts that it stays that way |
+| Data | `open-notebook-data:/app/data` (named volume: uploads, LangGraph SQLite checkpoints, extraction caches) **plus** the interim host bind `/home/dank/media/podcasts:/app/data/podcasts` (`open-notebook.container:87-88`); database in the `open-notebook-db` named volume |
+| Networks | app: `dankclaw_default` first, then the private `systemd-open-notebook` (10.89.4.0/24, `open-notebook.network:33`); database: the private bridge only. Order is load-bearing — the generated `--network` flags keep file order, so the default route rides the network where `host.containers.internal` is proven |
+| Units | `dankclaw/open-notebook/quadlet/open-notebook.container` → `open-notebook.service`; `open-notebook-surrealdb.container` → `open-notebook-surrealdb.service`; both `Restart=always`, `RestartSec=10` / `5`, `[Install] WantedBy=default.target` — boot-persistent per [[Quadlet Lifecycle]] (generated units cannot be `enable`d on this host; the `[Install]` section is what the v1 generator honors at user-manager start) |
+| Health | app: `curl -fsS http://127.0.0.1:5055/health` (`open-notebook.container:89`); database: `/surreal is-ready` (`open-notebook-surrealdb.container:73`) |
+| Env | `scripts/open-notebook.env` (repo, knobs) then `/home/dank/Containers/open-notebook/env` (host, secrets, mode 600) — two `EnvironmentFile=` lines per unit, repo file **first** because the last file wins |
+| Deployer | `deploy_open_notebook` in `scripts/deploy-remote.sh`: seed secrets → ensure both digest pins are in local storage → install both units + the network → `mkdir -p /home/dank/media/podcasts` → restart database, wait for its container health → restart app → `wait_for_health open-notebook http://127.0.0.1:5056/health 180` |
+
+## What the image actually runs
+
+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:
+
+- **One unit owns the whole app.** There is no separate worker or frontend container to scale or restart, and the frontend refuses to start until the API answers (`wait-for-api.sh && node server.js`, `supervisord.conf:39`) — so gating the API gates the UI.
+- **The worker's concurrency comes from the environment**, not a flag baked into the image: `--max-tasks ${OPEN_NOTEBOOK_WORKER_MAX_TASKS:-5}` (`supervisord.conf:25`). Setting it in the env file is a real change, not decoration.
+
+Also from the image itself: `WORKDIR /app` and `EXPOSE 8502 5055` (`Dockerfile:84`, `:126`), **no `USER` line** (the app runs as container root, which in this host's rootless map lands as `dank` — the [[Seerr]] UID note measured `0 → 1000` on this machine), and `curl` **and** `ffmpeg` installed in the runtime layer (`Dockerfile:74-76`) — curl makes the health probe possible without a shell wrapper, ffmpeg is how the per-line clips become one file.
+
+`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.
+
+## Provisioning the providers (after first boot; UI or REST, never a unit)
+
+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`).
+
+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.
+
+**Verify reachability before saving**, from inside the container, because both addresses are netns-dependent:
+
+```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
+```
+
+**The blocker to state plainly:** frank-tts is built, named and tested but **not deployed** — nothing answers on 7772 (`ss -ltn`, Dankclaw, 2026-10-18; [[Local TTS and Voice Cloning]] records the same census). open-notebook deployed today writes scripts and fails at the first voice line. frank-tts ships first, or podcast generation waits.
+
+**Why frank-zealot and not frank-dragoon:** podcast scriptwriting asks the model for a JSON-schema response (with a plain-JSON fallback). llama.cpp's OpenAI-compatible endpoint is a known-good target for that; frank-dragoon's halogen runtime has **unverified** structured-output behaviour, 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
+
+A **speaker profile** carries one to four speakers (`docs/3-USER-GUIDE/creating-podcasts.md:27`), each with a personality and a **Voice ID that is typed exactly and passed through to the TTS request untouched** (`:29`) — there is no whitelist, no enum, no validation against a voice list. So the fleet's voice-pack names work verbatim:
+
+| Speaker | Voice ID to type |
+|---------|------------------|
+| Speaker 1 | `narrator1` |
+| Speaker 2 | `narrator2` |
+| Speaker 3 | `narrator3` |
+
+Those are the pack names frank-tts resolves from `/home/dank/voices` (`scripts/frank-tts.env` header: a voice is real exactly when `/voices/<name>/reference.wav` exists). Two traps, both from upstream's shipped defaults:
+
+- The three seeded speaker profiles carry **OpenAI voice names** (`nova`, `alloy`, …) and **no voice model at all** — they show a "Setup required" badge, and generation fails with a voice error until they are edited (`creating-podcasts.md:13`, `:33`; `local-tts.md:89`). Add a `narrator1`/`narrator2` pair (or a third/fourth) rather than editing the seeded ones in place.
+- Two speakers with the same voice are hard to follow (`creating-podcasts.md:89`). Distinct packs per speaker is the point of the 1–4 shape.
+
+## Two buttons that fail against frank-tts, and why that is cosmetic
+
+- **Test Connection** probes `GET <base_url>/models` (`open_notebook/ai/connection_tester.py:208-229`). frank-tts serves exactly two GET routes — `/health` and `/v1/audio/voices` — and 404s every other path (`dankclaw/voiceservice/app.py:228-238`). The button reports a failure against a healthy server.
+- **Discover Models** does the same `GET <base>/models` (`open_notebook/ai/model_discovery.py:26-28`) and finds nothing to list.
+- The TTS test path also synthesises with a **hard-coded voice `alloy`** for `openai_compatible` (`connection_tester.py:328-336`), which is not a fleet voice pack and would be refused even if the probe reached frank-tts.
+
+None of it blocks anything: model rows are added **by name** ("If a model isn't listed, type its id and click Add", `local-tts.md:82`) and the Voice ID field is free text. The failure is a missing `/models` route on a deliberately minimal shim, not a broken credential. The honest end-to-end test is a real generation job, or the `podman exec … curl /v1/audio/speech` call frank-tts's own seam documents.
+
+## The CPU guard, and why both numbers are 1
+
+Defaults are `TTS_BATCH_SIZE=5` and `OPEN_NOTEBOOK_WORKER_MAX_TASKS=5` (`docs/5-CONFIGURATION/environment-reference.md:129-130`) — five parallel synthesis requests from five parallel jobs. frank-tts spawns an engine process per request (about 8 GiB resident, 8 threads, from the frank-tts CPU trial of 2026-10-18; `scripts/frank-tts.env` pins `LLAMA_TTS_THREADS=8`), on a machine that also serves frank-dragoon and frank-zealot. Five of those is ~40 GiB and forty threads competing with two LLM endpoints for the same cores. `scripts/open-notebook.env:87-88` sets both to 1: one episode at a time, one voice line at a time. Upstream's own guidance is the same direction ("Set 1 for a local model on a single GPU", "Lower it … for rate-limited or single-threaded TTS servers").
+
+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".
+
+## 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`).
+
+The tracked file declares the secrets **empty** and the host file supplies them; podman applies `--env-file` arguments in order and the last one wins (verified against the generated `ExecStart` line, 2026-10-18). Reordering the two `EnvironmentFile=` lines in a unit would blank every credential — that is the trap the seam's ordering assertion exists for.
+
+The database has the same trap in a different spelling: the app reads `SURREAL_PASSWORD`, the `surreal` CLI reads `SURREAL_PASS` (its `start --help` prints `[env: SURREAL_PASS=]`; measured against the pinned digest). One value, written twice, by the seed function — so the pair cannot be given different root passwords. Both arrive through the environment, **not** through `Exec=`: `--pass` on the command line would put the database password in `/proc/<pid>/cmdline`, readable by any `ps` on the host. Measured with the pinned image: env-only credentials produce `Initialising credentials user=…`, the root user is created on first boot, a correct login authenticates and a wrong password is refused — no `--user`/`--pass` flags needed, and no `--bind` either, because the image's own `SURREAL_BIND=0.0.0.0:8000` is what makes the RPC reachable from another container at all.
+
+## Episode destination: interim, and reversible (issue #7)
+
+**Episode files currently exist in two places by design.** The app's own state stays in the `open-notebook-data` named volume; finished audio additionally lands on the host, because `/home/dank/media/podcasts` is bind-mounted over `/app/data/podcasts` (`open-notebook.container:88`). That is the **interim** answer to where episodes live: the destination is an open decision tracked as **Gitea issue #7, labelled `human-only` — agents must not work it.** Until Frank settles it, episode MP3s are ordinary files in his home directory, readable without `podman unshare`, which the database volume would require (measured with the pinned SurrealDB image).
+
+Reversibility is one line: delete the `Volume=/home/dank/media/podcasts:/app/data/podcasts` line and the episodes go back to living solely inside the named volume. Nothing else in the config assumes the bind. See [[Storage Policy]] for the repo's storage conventions this interim state deliberately bends.
+
+## Deploying, and the digest-pull step
+
+```bash
+# on Dankclaw, as dank — the pins are Pull=never, so fetch them first
+podman pull docker.io/surrealdb/surrealdb:v2@sha256:e5d7387e3727bbe2f7cd6d869e48cd34777272258572ead37c9656b25f745723
+podman pull docker.io/lfnovo/open_notebook:v1-latest@sha256:54b2025a4a4853c188f74b9b8246eca8c5480e5dd1babfa92db1038ff2f30212
+```
+
+`deploy_open_notebook` runs the same two pulls when the image is absent from local storage, so the manual step is only needed to pre-seed an offline host or to bump a pin. Then `scripts/deploy.sh --target dankclaw --service open-notebook`. Both `Pull=never` and the pin comment live in the unit files; upgrading means **editing the digest**, not repulling a tag — see [[Deployment Flow]].
+
+## Rollback
+
+- **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.
+- **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.

+# Voice Packs
+
+A **voice pack** is the unit of identity for **frank-tts**: one directory under
+`/home/dank/voices`, named by the voice, carrying the reference audio that makes
+the name real plus the pinned engine's own speaker artifacts and a provenance
+record. `voice=narrator1` on `POST /v1/audio/speech` resolves to
+`/home/dank/voices/narrator1/reference.wav` and to nothing else — a name without
+that file is a 400 that lists the names that do exist, because a silent fallback
+voice is how a wrong-voice endpoint stays wrong for weeks.
+
+**Host:** Dankclaw (192.168.0.143) — **Pack root:** `/home/dank/voices`, host
+state that stays out of the repo, mounted read-only at `/voices` by the façade
+unit — **Builder:** `scripts/build-voice-pack.sh` with tunables in
+`scripts/voice-packs.env` — **Seam:** `tests/voice_pack_unit.bats` — **Engine:**
+arm A `qwentts.cpp`, decided in [[Local TTS and Voice Cloning]].
+
+Packs are **world-readable on purpose** (`drwxr-xr-x`, owner `dank`): the façade
+container runs as uid 10000 and reads the mount from outside its own uid map.
+
+## The required files
+
+| File | What it is | Who reads it |
+|------|------------|--------------|
+| `reference.wav` | the crop: 24 kHz mono `pcm_s16le`, **18–25 s** of clean single-speaker audio | the façade (it is the existence gate for the name) and the engine's boot warmer, which base64s it and registers the voice with no transcript |
+| `reference.spk` | the engine's x-vector: **8,192 B** = `enc_dim` 2048 × f32 | the engine, for the ICL/`--ref-spk` path |
+| `reference.rvq` | the engine's RVQ code stream: **5,456–6,864 B**, 16 codebooks × T frames packed at 11 bits = 22 B per 12.5 Hz frame | the engine, for the ICL/`--ref-rvq` path |
+| `manifest.json` | provenance: source path and sha256, crop start/end offsets, sample rate, duration, the tool and engine commit that made the artifacts, and the `voice` name | humans, and the builder itself on its second gate assertion |
+
+`qwen-codec.log` rides along with the extractor's own record of the run; the
+façade ignores anything it does not name and never deletes anything.
+
+Division of enforcement, which is deliberate and not a gap: the **façade** gates
+on `reference.wav` because that is the only engine-agnostic term (see the
+voice-pack law in `scripts/frank-tts.env`); the **builder** is what refuses to
+emit a pack without its engine artifacts; the **engine** registers a voice from
+the WAV alone because its own `POST /v1/audio/voices` refuses a lone embedding —
+it wants `wav_b64` or **both** `spk_b64` and `rvq_b64`. So the artifacts are in
+the pack to make ICL a per-voice opt-in, not to boot it.
+
+## How a pack is built
+
+```bash
+# everything except the extractor: gate, crop, probe, plan, the manifest it would write
+scripts/build-voice-pack.sh --dry-run narrator1 /home/dank/voices
+
+# the real thing, on the host that holds the engine build
+scripts/build-voice-pack.sh narrator1 /home/dank/voices
+```
+
+Crops come from `scripts/voice-packs.env` — per voice: source path, offset,
+duration, and the source's pinned sha256 — and any of them can be overridden on
+the command line (`--source`, `--offset`, `--duration`, `--sha256`, `--tool`).
+`--all` walks `VOICE_PACKS`. The builder assumes no GPU, no container, no fleet
+endpoint and no network: `ffmpeg` cuts the crop, the pinned extractor makes the
+artifacts, and both run `nice -n 19` so a build never competes with the text
+endpoints on that box.
+
+The extractor is `qwen-codec` in the `qwentts.cpp` tree at
+`VOICE_PACK_ENGINE_COMMIT` (`5916bf7c79dbb4e66fc059cdc507a79a23a28bb4`). Its
+usage text, read out of that tree and not guessed:
+
+```
+Usage: qwen-codec --model <gguf> [-i <input>] [--talker <gguf>] [--format <fmt>]
+
+Required:
+  --model <gguf>          Codec GGUF (qwen-tokenizer-12hz-*.gguf)
+
+Optional:
+  --device <name>         Compute device: CUDA0, Vulkan0, MTL0, CPU...
+                          (default: best available)
+  -i <path>               Input. WAV -> encode, .rvq -> decode
+  --talker <gguf>         Talker GGUF (Base only). Encode also extracts the speaker
+                          embedding and writes it next to the .rvq as a .spk file
+  --format <fmt>          WAV output format: wav16, wav24, wav32 (default: wav16)
+
+Output is auto-named next to input : clip.wav -> clip.rvq, clip.rvq -> clip.wav.
+```
+
+Three consequences shape the builder. **There is no `-o`**, so the pack's WAV is
+staged under its final stem and the artifacts land beside it with nothing to
+rename. **`--talker` must be a _Base_ talker** — the customvoice and voicedesign
+GGUFs carry no speaker encoder and the tool says `has no speaker encoder (Base
+only)`. **Encode truncates to the hop boundary**, so the `.rvq` size is arithmetic,
+not chance: `22 × floor(samples / 1920)` bytes, which is where the recorded
+5,456–6,864 B window comes from and why the **effective crop window is
+19.84–25 s** even though the WAV law says 18–25 s. A crop shorter than that is
+refused before the extractor runs, with the number in the message.
+
+The build is staged and published, never assembled in place: `reference.wav` is
+the file the façade reads, so it moves into position **last**, after the
+artifacts and the manifest. A failed extractor therefore leaves a pack directory
+that is not a voice. Nothing is ever deleted — an existing pack is refused unless
+`--force`, and `--force` moves the whole old directory to
+`/home/dank/voices/.AGENTTRASH/<voice>-<UTC>/` and builds fresh beside it.
+
+Measured on the shipped `narrator1` crop (2026-10-18, `--dry-run` against the
+real source): 98.739–118.636 s → `955,378 B` of 24 kHz mono `pcm_s16le`, 19.897
+s, planned `.rvq` 5,456 B — the same byte counts the trial produced by hand, and
+the extractor itself costs 1.8–2.1 s and 1.3–1.5 GiB peak per voice.
+
+## The 10-second gate
+
+Project-wide source-material invariant: **the first 10 seconds of any sample
+file used to generate voices is forbidden material.** An offset that starts
+inside it is refused with exit 1 and a message that names the invariant, before
+a directory is created:
+
+```
+ERROR: source-material invariant violated: the crop must start past the first
+10 s of the source file, and 'narrator1' asks for 4.5 s into … — nothing was
+written.
+```
+
+The same gate is then asserted **from the manifest** that was just written —
+`.crop.offset_seconds >= .invariant.forbidden_source_seconds`, plus the recorded
+sha256 against the source it claims — so a pack cannot reach disk carrying a
+forbidden crop even if the offsets in the env file are edited into nonsense.
+`10` is not a knob: `scripts/voice-packs.env` carries the offsets, the sample
+rate, the windows and the engine facts, but the forbidden region is a constant in
+the builder. `tests/voice_pack_unit.bats` pins both halves (a refusal that
+creates nothing, and one legal crop that builds the whole pack) and applies the
+invariant to every crop in the tracked pack list.
+
+## Adding a fourth voice
+
+1. Pick the source file and hash it: `sha256sum /path/to/sample.wav`. A crop
+   offset is a claim about one exact file, so the digest goes in the env with it.
+2. Find a speech-dense stretch **past 10 s**. The trial's recipe, applied once:
+   `ffmpeg -ss 60 -t 600 -i SRC -af silencedetect=noise=-35dB:d=0.6 -f null -`,
+   build the runs of non-silence, keep runs ≥ 18 s, take the longest (earliest
+   on ties), and cap at 25 s. Aim for 20–25 s: shorter than 19.84 s and the
+   `.rvq` falls under the floor.
+3. Add the four lines to `scripts/voice-packs.env` and the name to
+   `VOICE_PACKS`:
+
+   ```
+   VOICE_PACKS="narrator1 narrator2 narrator3 narrator4"
+
+   VOICE_PACK_NARRATOR4_SOURCE=/home/dank/voice-sources/audiosample4.m4b
+   VOICE_PACK_NARRATOR4_OFFSET=142.31
+   VOICE_PACK_NARRATOR4_DURATION=24
+   VOICE_PACK_NARRATOR4_SHA256=<64 hex>
+   ```
+
+   The name must be lowercase `[a-z0-9._-]`: the façade matches the directory
+   name verbatim while `tts-server` lowercases names internally, so an uppercase
+   name would be reported one way by the façade and another by the engine. The
+   builder refuses one anyway.
+4. `scripts/build-voice-pack.sh --dry-run narrator4 /home/dank/voices`, read the
+   plan, then drop `--dry-run`.
+5. `./tests/run.sh` (the pack-list invariant test covers the new row for free).
+6. Register it with the running engine. The engine's voice registry is
+   memory-only and warm-on-boot, but a restart re-decodes **every** voice (6–8 s
+   each), so adding one pack uses the hook instead:
+
+   ```bash
+   podman exec frank-tts-engine /app/warm-voices.sh
+   curl -s localhost:7772/v1/audio/voices      # the façade's list, not the engine's
+   ```
+
+   The hook walks `/voices`, registers any pack with a `reference.wav` it has not
+   seen, and logs `voice <name> cold=…ms warm=…ms` to the unit's journal. The
+   rootless unit restart — `systemctl --user restart frank-tts-engine.service` —
+   is for when the unit or its env changed, not for a new pack.
+
+## When the extractor's output size changes on an engine bump
+
+The builder treats the two artifact sizes as properties of the pinned engine, so
+an engine bump that changes them **fails the build**: `reference.spk is N B,
+expected 8192 B` or `reference.rvq is N B, expected …`. That is the failure being
+loud, not a bug. Work through it in order:
+
+1. Re-read the tool's own numbers rather than trusting this page: `qwen-codec`
+   prints `SpeakerEncoder] Loaded: enc_dim=…` and `Pipeline] Ready: hop … , …
+   codebooks @ … Hz` on every run, and the pinned tree's
+   `tools/qwen-codec.cpp` documents the packing. `enc_dim × 4` is the `.spk`;
+   `codebooks × code_bits / 8` bytes per frame × frames is the `.rvq`.
+2. Decide whether the new number is intended. A changed `enc_dim` means the old
+   `.spk` files are unreadable by the new engine, so **every** pack must be
+   rebuilt, not just the failing one.
+3. Update the four arithmetic lines in `scripts/voice-packs.env`
+   (`VOICE_PACK_SPK_BYTES`, `VOICE_PACK_RVQ_MIN_BYTES`, `VOICE_PACK_RVQ_MAX_BYTES`,
+   and `VOICE_PACK_RVQ_BYTES_PER_FRAME` if the codebook packing changed) **and**
+   `VOICE_PACK_ENGINE_COMMIT`, `VOICE_PACK_TOOL`, `VOICE_PACK_CODEC_MODEL`,
+   `VOICE_PACK_TALKER_MODEL` to the new build. An env diff that moves the sizes
+   without moving the commit is the mistake to avoid.
+4. Rebuild all three packs with `--force` (the retired directories keep the old
+   bytes readable beside their replacements until a human clears them), then
+   restart the engine rather than using the warm hook: the hook only registers
+   packs it has **not** seen, and every voice here is already registered against
+   the old artifacts. `systemctl --user restart frank-tts-engine.service`
+   re-warms them all from the new bytes.
+5. `./tests/voice_pack_unit.bats` — the stub in that seam reproduces the packing
+   law, so it needs the same arithmetic update as the env file. The seam's
+   engine-bump test is exactly this scenario with a wrong `.spk` size, and its
+   assertion — no `reference.wav`, no manifest — is the property that matters.
+
+## Host state (census 2026-10-18, read-only)
+
+- `/home/dank/voices/` holds `narrator1`, `narrator2`, `narrator3`, each with
+  `reference.wav`, a `reference16k.wav`, and a `manifest.json` **in the trial's
+  own schema** (`kind: voice-reference-pack`, a silence-scan record). They carry
+  **no** `reference.spk` / `reference.rvq`: the trial's artifacts live in its own
+  work directory (`/home/dank/voice-audition/qwentts/voices/`, and only for
+  narrator1 and narrator2). The builder's first real run is therefore a
+  migration, and it should be a `--force` run per voice so the old directories
+  are retired rather than left half-updated.
+- The three source files (`/home/blank/audiosample.mp3`,
+  `audiosample2.m4b`, `audiosample3.m4b`, digests pinned in
+  `scripts/voice-packs.env`) live on the workstation, not on Dankclaw; the
+  builder reads them from `$VOICE_PACK_SOURCE_DIR=/home/dank/voice-sources`, so
+  they have to be copied there once before a build.
+- `VOICE_PACK_TOOL` points at the trial's build tree
+  (`/home/dank/voice-audition/qwentts/qwentts.cpp/build/qwen-codec`, checked out
+  at exactly `5916bf7c`), and the two GGUFs at
+  `/home/dank/models/Qwen3-TTS-GGUF/`, which is where the engine slice's
+  download script puts them — that directory does not exist yet, so until it
+  does the models have to come from the trial's `models/` directory.
+- Nothing is deployed: nothing listens on 7772 or 8880 today, so building packs
+  is possible on that host while serving them is not.
+
+## Known gaps, on purpose
+
+- **No transcript in the manifest.** ICL wants a `ref_text` that matches the
+  crop, and the trial's machine transcripts came back wrong ("Demon Souls" for
+  *Dark Souls*). Transcribing on the host is not a fix, so the pack carries none
+  and the engine registers the WAV-only voice, which is what its boot warmer
+  does anyway. When ICL becomes a per-voice opt-in, the curated transcript
+  belongs in this manifest — a human-supplied field, not something the builder
+  can derive.
+- **No 16 kHz variant.** The packs the trial left behind carry
+  `reference16k.wav` for the `llama-tts-cli` rollback engine; arm A is native
+  24 kHz, so the builder emits one reference. `--force` retires the whole
+  directory including that variant, so if the rollback engine is ever revived:
+  `ffmpeg -i reference.wav -ar 16000 -c:a pcm_s16le reference16k.wav`.
+- **No loudness pass.** The trial's pipeline also measured and normalised
+  (two-pass `loudnorm`, `astats`, `ebur128`, spectrograms) to a `-16 LUFS` spec.
+  None of that is in the pack law, which asks for 24 kHz mono inside the
+  duration window, so the builder does only that; a future engine that is
+  loudness-sensitive should get the pass as an explicit, documented step.

+
+Both candidate upstreams for frank-tts were measured on Dankclaw's CPU — 8
+threads, no GPU touched, three runs per arm, seed 42, identical text, against
+the fleet's own audition voice packs.
+
+- **Arm A — [`ServeurpersoCom/qwentts.cpp`](https://github.com/ServeurpersoCom/qwentts.cpp)**
+  at commit `5916bf7c79dbb4e66fc059cdc507a79a23a28bb4` (2026-10-16), weights
+  from [`Serveurperso/Qwen3-TTS-GGUF`](https://huggingface.co/Serveurperso/Qwen3-TTS-GGUF):
+  `qwen-talker-1.7b-base-Q4_K_M.gguf` (1,219,245,248 B),
+  `qwen-talker-0.6b-base-Q4_K_M.gguf` (628,905,056 B),
+  `qwen-tokenizer-12hz-Q8_0.gguf` (291,150,624 B) — byte counts verified
+  against the Hub API. Builds with zero compiler warnings; `GGML_BLAS=OFF` is
+  forced on this host (only `libopenblas.so.0` exists, no dev headers, so the
+  vendor `buildcpu.sh` cannot configure).
+- **Arm B — mainline `llama-tts`** with `--tts-speaker-file`, i.e. the
+  `llama-tts-cli` backend `scripts/frank-tts.env` already implements.
+
+RTF is **seconds of compute per second of audio** (lower is better; below 1 is
+faster than real time).
+
+| Arm | RTF | Run spread | Peak RSS |
+|---|---|---|---|
+| A · 0.6 B talker, CLI | 0.44 | ±0.002 | 3.4 GiB |
+| A · 1.7 B, CLI, uncloned | 0.57–0.58 | ±0.006 | 4.7 GiB |
+| A · 1.7 B, CLI, embedding-only clone | 0.63 | ±0.02 | n/m |
+| A · 1.7 B, CLI, ICL clone | 0.92 | ±0.01 | n/m |
+| A · 1.7 B, resident `tts-server`, warm | 0.55–0.57 | ±0.01 | 5.7 GiB |
+| A · same, ICL voice warm / **cold (first request)** | 0.67 / **1.65** | one-shot | 5.7 GiB |
+| B · mainline `llama-tts` | 0.93–0.99 | ±0.25 | n/m |
+
+**Read RTF only within an arm.** Conditioning changes clip length — the same
+seed yields 18.00 s of audio embedding-only and 15.12 s under ICL — so the
+denominator is the arm's own audio duration.
+
+Arm A's resident server is ~1.7× faster than arm B and about 40× tighter in
+run-to-run spread, and it already serves the HTTP shape frank-tts's façade
+speaks: `/health`, `/v1/models`, `/v1/audio/voices` (GET/POST/DELETE),
+`/v1/audio/speech` (`wav`/`pcm`), chunked streaming with the first audio byte
+at 86–451 ms and a server-side time-to-first-audio of 94–112 ms. Arm B has no
+HTTP path at all — that is what the façade's CLI backend exists for.
+
+Four laws came out of the trial, each worth a line of configuration:
+
+- **Boot-warm every voice.** The first request for a registered voice decodes
+  the whole reference to snapshot codec state: 6.2–8.0 s, first audio byte at
+  5,530 ms. Later requests restore that state in 0.5 ms. An engine unit must
+  run one throwaway synthesis per voice at start, or the first request of the
+  day pays five seconds.
+- **Speaker artifacts are reusable and exact.** `qwen-codec` turns a reference
+  WAV into `.spk` (8,192 B x-vector) + `.rvq` (5,456–6,864 B, 16 codebooks × T,
+  11-bit packed) in 1.8–2.1 s at 1.3–1.5 GiB peak; replaying them yields a
+  **byte-identical** WAV and saves 1.4 s per request. That pair is the
+  engine-artifact term the voice-pack law in `scripts/frank-tts.env` reserves a
+  slot for — arm A pins it as `.spk` + `.rvq` beside `reference.wav`.
+- **Streaming is not bit-identical to buffered**, whatever the upstream README
+  claims: same text, seed and voice, 92.2 % of samples differ (peak delta
+  1139/32768, −41.6 dB RMS — inaudible). A fixed seed does not pin output
+  across `response_format`, so never mix the two paths in a cache or a golden
+  fixture.
+- **A voice cannot be registered from an embedding alone**: `POST
+  /v1/audio/voices` accepts `wav_b64` or **both** `spk_b64` and `rvq_b64`
+  (`src/tts-server.h:480`), so an embedding-only voice has to be sent as the
+  WAV, or the lone-`spk` path has to be upstreamed.
+
+**Likeness is not measurable at this resolution.** x-vector cosine against each
+speaker's own reference: ICL 0.9886 / 0.9901, embedding-only 0.9844 / 0.9812,
+uncloned 0.9228 — but **two different speakers score 0.9497** on the same
+metric. The whole clone effect lives in a 0.04-wide band and the
+ICL-over-embedding gap is inside noise, so the four audition clips
+(`/home/blank/voice-audition/qwentts-*.mp3`, each against its `armB-*.mp3`
+mainline partner, guide in `LISTEN-engine.md`) are the instrument. **The
+operator heard them on 2026-10-18 and passed every clone**, which removed the
+last axis measurement could not reach; the engine was then picked on
+live-output grounds ([Decision](#decision-arm-a-for-live-output-2026-10-18)).
+The cosine
+extractor is still worth keeping: it is engine-neutral (it scores mainline
+output through the same encoder) and it separates an uncloned voice cleanly.
+
+Two operational details. The engine takes 8 threads and exposes **no `-t`
+flag** — `src/backend.h` uses `hardware_concurrency()/2` and prints the choice
+at load, so pinning a cpuset on the quadlet changes that number implicitly. And
+ICL needs a reference transcript that did not exist: the fleet has no ASR
+endpoint and no audio input, so the crops were transcribed with
+`vosk-small-en-us` inside the work dir, and two of three transcripts came back
+suspect ("demon souls" for *Dark Souls*) — a reason to curate `ref_text` into
+the pack manifest instead of transcribing on the host.
+
+## Decision: arm A for live output (2026-10-18)
+
+Every audition pair passed, so likeness stopped being the tiebreak. The
+question became **which engine is better for live output** — the harness
+speaking a reply, an alert read aloud, a click-to-speak — and on that criterion
+RTF only has to stay under 1.0 with margin: what separates the arms is **time to
+first audio** and the **spread**, because an arm whose RTF can cross 1.0 stalls
+a live stream mid-sentence.
+
+| | arm A · `qwentts.cpp` `tts-server` | arm B · mainline `llama-tts` |
+|---|---|---|
+| first audio byte | 86–451 ms | model load, per request |
+| warm RTF | 0.55–0.67 | 0.93–0.99 |
+| run spread | ±0.01 | ±0.25 |
+| HTTP | serves `/v1/audio/speech` | none — façade CLI only |
+| RAM | 5.7 GiB resident | per-request, freed after |
+
+**Chosen: arm A, 1.7 B talker, resident `tts-server` in a `frank-tts-engine`
+container, with `TTS_BACKEND=llama-tts-cli` kept in the repo as the rollback.**
+Three consequences are configuration, not opinion: the unit **boot-warms every
+voice** (5.5 s cold first byte otherwise), it **does not pin a cpuset** casually
+(threads are `hardware_concurrency()/2`, no flag), and every pack registers with
+the **WAV** because the engine rejects a lone embedding.
+
+Two follow-ups stay open on purpose, and neither blocks the deploy:
+
+- **Talker size.** The 0.6 B arm measured 0.44 RTF at 3.4 GiB and has never
+  been auditioned — every clip above is 1.7 B. It is the lever for a CPU
+  co-tenancy problem, not a preemptive saving.
+- **ICL vs embedding-only.** Both passed the ear test. Embedding-only is the
+  shipped default: 0.57–0.63 vs 0.67 warm, and it needs no `ref_text`, which
+  this fleet cannot produce honestly (the ASR crops came back suspect). Packs
+  still carry `.spk` + `.rvq`, so ICL remains a per-voice opt-in for batch work
+  like the podcast render, where total time matters more than first byte.

+## 2026-10-18 — TTS engine picked: arm A `qwentts.cpp`, on the live-output criterion
+
+- Frank listened to the four audition pairs (`qwentts-*.mp3` against their
+  `armB-*.mp3` mainline partners) and **passed every clone**. That deleted the
+  only axis the A/B could not measure, and the question was reframed: **which
+  engine is better for live output**. On that criterion RTF only has to stay
+  under 1.0 with margin — the discriminators are time-to-first-audio and
+  run-to-run spread, because an arm whose RTF can cross 1.0 stalls a live
+  stream mid-sentence.
+- **Chosen: arm A `qwentts.cpp` @ `5916bf7`, the resident `tts-server`, 1.7 B
+  talker Q4_K_M + Q8_0 tokenizer, in a `frank-tts-engine` container on 8880.**
+  The `TTS_BACKEND=llama-tts-cli` path in `scripts/frank-tts.env` stays in the
+  repo as the rollback. The numbers that carried it: first audio byte 86–451 ms
+  against a per-request model load, warm RTF 0.55–0.67 against 0.93–0.99, spread
+  ±0.01 against ±0.25, and a native `/v1/audio/speech` against no HTTP path at
+  all. Three consequences are configuration, not preference: boot-warm every
+  voice, do not pin a cpuset (threads are `hardware_concurrency()/2`), register
+  every pack with its WAV (a lone embedding is rejected).
+- Two follow-ups deliberately **not** decided: the **0.6 B talker** (0.44 RTF,
+  3.4 GiB, never auditioned — every clip is 1.7 B) and **ICL vs
+  embedding-only** conditioning. Embedding-only is the shipped default because
+  it is cheaper and needs no `ref_text`, which this fleet cannot transcribe
+  honestly; `.spk` + `.rvq` still ride in every pack, so ICL remains a per-voice
+  opt-in for batch work where total time beats first byte.
+- **Addressing law corrected** in
+  [[Local TTS and Voice Cloning]]: the pair may not meet at a host-loopback
+  publish. netavark DNATs published ports only and a bridge container cannot
+  reach a host `127.0.0.1` bind — the lesson that 502'd hermes — so
+  `host.containers.internal:8880`, which `scripts/frank-tts.env` documents, is
+  correct only for a routable bind. The deployed pair shares one quadlet network
+  and the façade addresses the engine by container name.
+- **PR #12** (`feat/open-notebook-podcast` @ `114dd7a`, 8 commits, 403 tests) is
+  **merged** as `1eb8b21` (Frank's OK, given in session): open-notebook +
+  SurrealDB quadlets on the private bridge `10.89.4.0/24`, the API published on
+  **5056** because seerr holds `127.0.0.1:5055`, and `ESPERANTO_TTS_TIMEOUT`
+  moved 600 → **660** to sit one round-trip outside frank-tts's own
+  `SHIM_TIMEOUT`. Merged is not runnable: nothing listens on 7772 until the
+  voice stack lands, and the episode destination (`/home/dank/media/podcasts`)
+  stays interim pending Gitea #7.
+- Still in flight, not in this branch: `feat/frank-tts-engine` — the arm A image
+  build, the quadlet pair on one network, the boot-warm step, deployer /
+  planner / `test-changed.sh` routing, homepage and docs. This branch is also
+  where the two-branch overlap got resolved: merging `main` here conflicted on
+  `log.md` alone (both branches appended an entry) and took `index.md`,
+  `deploy-remote.sh`, `deploy-plan.py` and `test-changed.sh` clean.
+
+## 2026-10-18 — open-notebook: the podcast generator's config lands (nothing deployed)
+
+- Goal: **open-notebook** as the fleet's podcast generator on Dankclaw — notes
+  and sources in, a multi-speaker episode out, script written by
+  **frank-zealot**, voices rendered by **frank-tts**, no cloud provider
+  anywhere in the path. Repo-side only: no host touched, no container pulled or
+  started. Runbook: [[Open Notebook]].
+- **Two containers, not one.** `lfnovo/open_notebook:v1-latest` plus
+  `surrealdb/surrealdb:v2`, both **digest-pinned** with `Pull=never` and a
+  documented one-time `podman pull` — frank-dragoon's pinning style, because
+  `:latest` moving underneath a rootless service is how you get an unbootable
+  pod after an unrelated `systemctl-daemon-reload`. The registry round-trip is
+  what proved `v2` is SurrealDB **2.7.0** and that the app image is Debian
+  trixie with **curl and ffmpeg already inside** — which is how both health
+  probes can be argument-only: `curl -fsS …/health` (route is upstream's,
+  `api/main.py:239`, and it sits on the auth exclude list) and
+  `/surreal is-ready`, which I ran against the digest here: green in 2 s, and
+  it refuses to pass without `SURREAL_PASS` in the environment — a credential
+  that must never ride the command line, so `Exec=` carries flags only.
+- **Host 5055 was already spoken for.** seerr has held `127.0.0.1:5055` since
+  2026-10-14 (live `ss -ltn` agrees today), so the API publishes
+  `0.0.0.0:5056:5055`. open-notebook's frontend derives its API URL from the
+  window origin when `API_URL` is unset — the upstream env reference spells the
+  reverse-proxy symptom — so a silent remap would hang the UI on a port nobody
+  listens on, and `API_URL=http://192.168.0.143:5056` is set accordingly. 8502
+  publishes on `0.0.0.0` because this service carries its own password (the
+  episode-audio route is unauthenticated), unlike the loopback-and-proxied
+  observability stack; **8000 is published nowhere**, where upstream exposes it
+  on loopback with root credentials, and the seam forbids it.
+- **The CPU guard, pre-armed.** `frank-tts` spawns one ~8 GiB, 8-thread engine
+  per request on a box that also serves two LLMs, while open-notebook defaults
+  to `TTS_BATCH_SIZE=5` × `OPEN_NOTEBOOK_WORKER_MAX_TASKS=5` — a five-way
+  self-DoS. Both are pinned to `1` in `scripts/open-notebook.env`, and the
+  worker knob is only real because the image's own supervisord expands
+  `${OPEN_NOTEBOOK_WORKER_MAX_TASKS:-5}` (`supervisord.conf:25`). The TTS clock
+  goes to **660 — one round-trip outside** frank-tts's own `SHIM_TIMEOUT=600`, so
+  a shim give-up reads as the shim's error rather than the worker's; the seam
+  asserts the direction (`>`) against the frank-tts env instead of restating a
+  number. `ESPERANTO_LLM_TIMEOUT` stays at the app's 180 s default: frank-zealot
+  answers an outline or a transcript well inside it, and upstream says to keep it
+  under 600 so a slow call fails with a name on it.
+- **What a credential needs in order to exist:** `OPEN_NOTEBOOK_ENCRYPTION_KEY`
+  must be set before the UI can save *any* provider credential, and
+  `OPEN_NOTEBOOK_PASSWORD` must stay **absent** to remain auth-off — the app
+  reads `os.environ.get(…) is not None`, so `PASSWORD=` boots a login form
+  asking for the empty string. The repo env file carries both keys empty; the
+  deployer seeds `/home/dank/Containers/open-notebook/env` (600) from the host
+  vault and **refuses to start the pair while either secret is blank**, because
+  a half-configured open-notebook stores no credentials and fails quietly.
+- **Episode destination is interim, by decision.** The destination is **Gitea
+  issue #7, `human-only`** — agents must not work it. Until Frank settles it,
+  the app keeps its own named volume and `/home/dank/media/podcasts` is
+  bind-mounted over `/app/data/podcasts` (`DATA_FOLDER` is hard-coded `./data`),
+  so finished MP3s are ordinary files in his home directory instead of volume
+  contents needing `podman unshare` — the database volume demonstrably lands on
+  a mapped subuid, measured with the pinned image. One mount line; one deletion
+  undoes it.
+- **Two UI buttons will fail, and that is cosmetic.** Test Connection does
+  `GET <base>/models` and the TTS probe synthesises voice `alloy`; frank-tts
+  serves `/health` and `/v1/audio/speech` only. Model rows are created *by
+  name* and the voice field is free text, so `narrator1/2/3` is typed in and
+  never discovered. Documented, not worked around.
+- **Blocked on frank-tts, stated plainly:** phase 1 landed without deployer or
+  homepage registration and nothing listens on 7772 today, so a generation run
+  writes its script and then fails on the first voice. That is upstream's
+  creation-podcasts warning in fleet clothing.
+- Suite green: **403/403** (`./tests/run.sh`, wall 67 s) — 19 tests in the new
+  `tests/open_notebook.bats`, structure only: pins, boot persistence, the
+  unpublishable database port, the 5055→5056 remap plus the `API_URL` that has
+  to match it, the env-file read order, the guard knobs, the health gate naming
+  `/health`, planner routing, the homepage card hidden while undeployed.
+- Three deployer seams cost time and are now law-shaped: a service must be
+  registered in **five** places — `SERVICE_ORDER`, `DANKCLAW_SERVICES`, the
+  `deploy-remote.sh` dispatch case, its pre-deploy requirement, and
+  `deploy.sh`'s dispatch regex, where an omission silently plans an empty set
+  for `--only`; a `dankclaw/<svc>/*` case must precede the `dankclaw/*.container`
+  glob because that `*` crosses `/`; and the changed-path routing lives *inside*
+  the per-path loop, after the `scripts/*.env)` case, not at the top of the file.
+- Deliberately NOT done: the deploy (pulling 1.27 GiB to Dankclaw was not
+  asked for), any Caddy vhost or public exposure, audiobook/EPUB (issue #5), any
+  `frank-tts` code change, and the harbor templates on Dankserver —
+  `~/.harbor/compose.opennotebook.yml` pins the deprecated `-single` image,
+  carries no encryption key and injects the whole harbor env — left untouched,
+  read-only, as the record of what not to copy.
+
+## 2026-10-18 — voice-pack builder: the 10-second source-material gate becomes code
+
+- Third slice of the voice stack (after the façade and the engine decision):
+  `scripts/build-voice-pack.sh` turns a source recording plus a crop offset into
+  a deployable pack — `reference.wav` (24 kHz mono `pcm_s16le`, 18–25 s), the
+  engine's own `reference.spk` (8,192 B) + `reference.rvq` (5,456–6,864 B) made
+  from it, and `manifest.json` provenance. Tracked tunables in
+  `scripts/voice-packs.env`: pack list, per-voice source/offset/duration/pinned
+  source sha256, extractor path and engine commit, artifact arithmetic. New runbook
+  [[Voice Packs]].
+- **The gate is the product.** The project-wide invariant — no voice material
+  from the first 10 s of a sample file — had only ever been a sentence in
+  `scripts/frank-tts.env`. An offset inside it now exits 1 before a directory is
+  created, and the same assertion runs again against the manifest that was just
+  written, next to the recorded sha256, so a pack cannot carry a forbidden crop
+  even if the env file is edited into nonsense. `10` stays a constant in the
+  builder; the env file carries offsets, never the law.
+- **The extractor's contract was read, not guessed:** `qwen-codec` in qwentts.cpp
+  `5916bf7c` takes `--model <codec gguf> --talker <base talker gguf> -i <wav>`
+  with an optional `--device`, has **no `-o`** and names both artifacts next to
+  the input with the extension swapped. So the WAV is staged under its final stem
+  and `reference.wav` — the file the façade gates on — is moved into place
+  **last**, after the artifacts and the manifest: a failed extractor leaves a
+  directory that is not a voice. `--force` retires an existing pack whole to
+  `.AGENTTRASH/` instead of touching bytes; nothing in this script deletes.
+- Sizes are arithmetic, so they are checked: 16 codebooks × 11 bits = 22 B per
+  12.5 Hz frame (`22 × floor(samples/1920)`) and `enc_dim 2048 × f32` = 8,192 B.
+  That makes the **effective crop window 19.84–25 s**, narrower than the WAV
+  law's 18–25 s, and a too-short crop is refused before the extractor runs. An
+  engine bump that changes either number fails the build by design; the bump
+  procedure is in [[Voice Packs]].
+- Verified against reality, not against the model: the pinned `narrator1` crop
+  (98.739–118.636 s of `audiosample.mp3`, sha256 `2299510…`) comes out of a
+  `--dry-run` at 955,378 B / 19.897 s with 5,456 B of `.rvq` planned — byte-for-byte
+  the trial's hand-cut numbers — and all three pinned source digests match the
+  files on disk.
+- Seam: `tests/voice_pack_unit.bats` (13 tests) — refusal inside the forbidden
+  region creates nothing, a legal crop builds the whole pack, `ffprobe` on the
+  generated reference, manifest round-trip through `jq` with a sha that matches
+  the source, re-run-without-`--force` leaves every byte alone, `--force` retires
+  rather than deletes, `--dry-run` needs no extractor, a wrong-sized artifact
+  from a bumped engine cannot publish a voice, and every crop in the tracked pack
+  list clears the invariant. `qwen-codec` is stood in by a stub with the real
+  tool's I/O shape, so no engine, no GPU, no network, no fleet host. Suite green:
+  **416/416** (`./tests/run.sh`, wall 77 s) — 403 before this branch.
+- Deliberately NOT done: no transcript in the manifest (ICL wants a curated
+  `ref_text`; the trial's machine transcripts were wrong, and the engine
+  registers WAV-only voices anyway), no 16 kHz variant (arm A is native 24 kHz),
+  no loudness pass (not in the pack law), and no pack built on the host — the
+  three sources still live on the workstation and the engine GGUFs have not been
+  fetched to `/home/dank/models/Qwen3-TTS-GGUF` yet, so the first real run is a
+  host step.

+# Seam: the voice-pack builder (scripts/build-voice-pack.sh).
+#
+# The contract this pins is the one frank-tts's packs live or die by. A crop is
+# only usable voice material if it starts PAST the first 10 seconds of the
+# source file — the project-wide source-material invariant — and this builder is
+# the thing that enforces it, because nothing downstream looks at offsets again.
+# A pack is three files plus provenance: reference.wav at 24 kHz mono inside the
+# 18-25 s window, the engine's own speaker artifacts beside it, and a
+# manifest.json whose sha256 still matches the bytes the crop came from. Builds
+# refuse to clobber what is already on disk, and --force retires rather than
+# deletes.
+#
+# No engine binary, no model, no GPU, no network and no fleet host: the crop is
+# cut from a locally generated tone and the pinned extractor is stood in by a
+# stub that mirrors the real tool's I/O shape (no -o flag: outputs named next to
+# the input with the extension swapped, at the sizes the codec's config
+# implies), which is how frank_tts_unit.bats drives its backends too.
