docs(frank-tts): worklog entry for the voice-stack audit

Three faults, all of the reporting-success-while-doing-nothing species: the
build that could not start (no adduser in the base), the warm pass that could
not warm (podman's --env-file keeps the quotes), and the image that would never
rebuild (cfhash over the Containerfile alone). Records the proofs, the two
behaviour seams, and what stays undone: nothing is deployed, #2 phase 1 stays
open until 7772 answers.

+## 2026-10-18 — voice stack audit: three faults that no gate could see
+
+- The voice stack had never been run end to end — no image built, nothing on
+  7772 — so the whole path was audited as static code against the tools it
+  calls, and three faults came out of it. All three are the same species: a
+  step that **reports success while doing nothing**.
+- **The build would not have happened.** `Containerfile.engine` created its
+  unprivileged user with `adduser`; the pinned ubuntu:24.04 base has no
+  `adduser` at all. Proven in the base on Dankclaw rather than argued from
+  memory: `command -v adduser` prints nothing, and the replacement line
+  `useradd --system --uid 10000 --home-dir /app --shell /usr/sbin/nologin tts`
+  answers `uid=10000(tts) gid=999(tts)`. Its `SYS_UID_MAX` warning is cosmetic
+  and is the price of matching the façade's uid, so the comment says that
+  before someone "fixes" it by dropping `--system`.
+- **The warm pass would not have warmed.** The unit hands its env file to podman
+  via `--env-file`, which performs no shell parsing and takes the literal
+  remainder of the line, while `source` strips one quoting layer. `WARM_TEXT`
+  therefore reached the container with its quotes, the hook interpolated them
+  into the synthesis body, the JSON was invalid, and every voice would log
+  "registered, but the warm synthesis failed" beside an `active` unit. Fixed in
+  the hook — strip exactly one matched pair, only when the inner content also
+  carries a quote or backslash, then JSON-escape — and the seam now reads
+  `scripts/frank-tts-engine.env` **both** ways and asserts the engine gets the
+  same sentence in both shapes. The bug survived the first deploy precisely
+  because every existing test used `source`.
+- **A rebuilt image would not have been rebuilt.** `build_compose_image` skips
+  `podman build` on a matching `cfhash` label, and that hash covered the
+  `Containerfile` alone — so editing `app.py` or `tts-engine-warm.sh` (both
+  `COPY`'d) skipped the build, the deploy reported success, `/health` answered,
+  and the container served old code. Each case arm now names the files its
+  `Containerfile` copies and hashes them with it; comfyui/loki/alloy have no
+  extras, so their labels are byte-unchanged and they do not rebuild here.
+- Tests as behaviour, not as greps: the new seam extracts the real
+  `build_compose_image` from the deployer and drives it against a stub `podman`
+  that replays per-image label state, asserting the observable question — did
+  the deploy ask podman to build, or did it skip? — through build, skip,
+  engine-hook-edit-rebuilds-engine-only, and `app.py`-rebuilds-the-façade.
+  Reverting `scripts/deploy-remote.sh` turns it red at the warm-hook step, which
+  is the fault being prevented. Suite green: **443/443** (`./tests/run.sh`,
+  wall 110 s); each fix commit was left green on its own so the branch bisects.
+- Docs carry the lessons where an operator will hit them: a **Locally built
+  images** section in [[deployment]], two new troubleshooting lines in [[Frank
+  TTS Engine]] (all-voices-cold = quoted `WARM_TEXT`; façade 502 beside engine
+  200 = model loaded ≠ voices registered), and `Voice Packs.md` step 4
+  corrected — the warm hook re-registers **every** pack on every run, because
+  the engine replaces a name it already holds (`tools/tts-server.cpp:148` at
+  the pinned commit: *"Re-registering a name replaces the previous entry."*),
+  so a restart is what an engine bump needs and not what a rebuilt pack needs.
+- Opened as PR **#14** against `main`. Deliberately NOT done: no deploy (the
+  first `--service frank-tts-engine` run is a ~10-minute recursive source clone
+  and a new unit on a host that serves people — Frank's call), no voice pack
+  built on the host, no Playwright run (this branch publishes no host port and
+  touches no vhost), and Gitea **#2** phase 1 stays open until 7772 answers.
