Alibaba's open-weight TTS (Apache 2.0, Jan 2026), deployed via
groxaxo/Qwen3-TTS-Openai-Fastapi wrapper. Built locally from a
pinned git SHA via docker buildx's git context — no source
vendored. 1.7B flagship model by default; 0.6B available via
QWEN3_TTS_MODEL env override.
Why we need a second TTS stack: cosyvoice 3 emits Chinese phonemes
for English content per upstream FunAudioLLM/CosyVoice#1790
(unfixed). Qwen3-TTS is from the same Alibaba team but with
English first-class in the checkpoint — 10 languages, 97 ms
streaming TTFB, instruction-driven emotion. Coexists with cosyvoice
on irv-ml1 (port 8191; cosyvoice keeps 8190).
Voice cloning shape DIFFERS from cosyvoice: profile-based, not
voice-id. Profiles live under voice_library/profiles/<name>/ and
are referenced as voice="clone:<name>".
Path layout: /worktank/qwen3-tts/{cache,voices}/, with cache excluded
from restic (regenerable from HF Hub) and voices included (cloned
profiles need original reference audio to recreate).
playbooks/deploy-qwen3-tts.yaml: 10 steps + 5 verify, idempotent;
the wait step polls /health for up to ~10 min to absorb first-run
model download.
Stack only — restic profile update for /worktank/qwen3-tts/voices/
to follow when this is empirically validated against the GLaDOS
voice (the "did Qwen inherit the Chinese-bias bug?" question).
STATUS.md:
- Mark 4b done (both Postgres migration + NFS decoupling)
- Add arch decisions for gitea remote + prefer-elway policy
- Add tooling entries for elway + tea CLI
- Document 2026-04-24 session milestones (irv-ml1 AI stacks,
elway, task-board, 4b finish)
- Expand memory-pointer list with the files added this session
CLAUDE.md:
- Tell new sessions to use elway for SSH-driven work, point at
the smoke playbook template
- Document the task-board plugin + MCP-tool contract so assistant
sessions with the plugin enabled know the assistant should call
task_start / task_update / task_wait / task_complete at
meaningful checkpoints
.claude/settings.json:
- Project-level env: TASK_BOARD_SESSION=Infra so every Claude Code
session opened here labels its task-board cards "Infra"
playbooks/decouple-pfi-postgres-from-ana-nas.yaml:
- Finishes the DB-off-NFS migration on pfi-postgres. Already ran
against prod today; fstab clean, unmounted, no systemd mnt-db
unit. Verify 3 was mis-expressed on first run (`grep -q active`
matched "inactive") — fixed to invert systemctl exit code
directly.
stacks/task-board/compose.yaml + .env.example describe the runtime —
image tag is task-board:local (built on the host), 7878 on host maps
to 7878 in container, SQLite lives at /opt/docker/conf/task-board/data/
(bind mount, uid 1000 friendly), homepage auto-card labels under
Toolchain group, on traefik-net like the rest of the fleet.
playbooks/deploy-task-board.yaml is the first real elway playbook —
exercises everything we built tier-1 + tier-2 idempotency for:
- `creates:` on mkdir + first-time clone + compose dir + data dir
- `when:` to chown /opt/docker/build only if it came up root-owned
- `when:` to seed .env only if one doesn't already exist (never
clobbers user edits on rerun)
- `changed_when:` on the `git reset --hard` step so repeat runs
against the same ref report `ok` instead of `changed`
- `changed_when: "false"` on every verify step (they attest, not
change)
- `upload:` with mode for compose.yaml + .env
Post-up the playbook polls /api/health for 30s before handing off to
the verify phase, so verification doesn't race the healthcheck's
start_period. Verify covers: /api/health 200, /api/tasks shape, /mcp
reachable, container on traefik-net.
Prereqs documented in the playbook header: Docker + compose plugin,
traefik-net network, git SSH access to gitea from the target host.
Tier 1 — pre-step skip conditions:
when: <remote shell expr> skip unless expr exits 0
creates: <remote path> skip if path already exists
removes: <remote path> skip if path is already absent
Any of the three saying "skip" marks the step `skipped` and moves on.
Evaluated under bash -c on the remote so `!`, `[[`, pipes etc. behave
consistently regardless of the default remote shell.
Tier 2 — post-step change detection:
changed_when: <remote shell expr>
Evaluated after a successful step. Exit 0 → step counts as `changed`
(default). Exit != 0 → `ok` (ran, nothing actually different).
Without this field, successful steps default to `changed`, matching
Ansible's shell/command defaults. Useful on verify steps:
`changed_when: "false"` reports them as `ok` since they only attest.
Status model moved from pass/fail to four states:
ok / changed / failed / skipped
Summary reports each count; overall outcome is CHANGED if any step
changed, OK if none did, FAILED on any non-skipped failure.
Rerunnable smoke: playbooks/elway-smoke.yaml now proves it. On a
clean target the cold run reports 4 changed, 3 ok. Rerunning with
the same vars reports 2 skipped / 2 changed (upload + log-record
have no idempotency hooks and are always `changed`). Overriding
--var greeting=... re-runs the gated step exactly as intended.
Doc block at the top of the script updated with the new schema
fields and state machine.
`scripts/elway` is a ~600-line Python tool (stdlib + python3-yaml) for
driving one-off ssh commands, ad-hoc file uploads, and YAML playbooks
against a single host. Fills the gap between "single ssh one-liner"
and "reach for Ansible."
Highlights:
- Three invocation modes: --shell, --upload (LOCAL:REMOTE[:MODE]),
and --playbook <path>
- Playbook schema: inline vars, list of steps, optional verify block.
Template via {{ var }}; CLI --var overrides inline defaults
- stop_on_fail global (default on), per-step override. Verify phase
always runs, even after a halt — you see end-state regardless
- Sudo handled once: probes NOPASSWD; if not, prompts locally via
getpass, validates up-front, then feeds via `sudo -S` per step.
Password never written to disk/logs. Upload-with-sudo stages to
/tmp then sudo-mv + sudo-chmod
- SSH connection reuse via ControlMaster (60s persist) keeps
multi-step playbooks responsive (~30ms/step reuse vs ~550ms cold)
- Live interleaved stdout/stderr with per-step prefix and colored
pass/fail summary. --dry-run prints the plan without executing
- Shebang pinned to /usr/bin/python3 to bypass venv-shadowing
when python3-yaml lives in the system site-packages
Smoke test (playbooks/elway-smoke.yaml) covers vars + upload + verify;
drove out a YAML-scalar-coercion bug before first commit (`shell: false`
parsed to Python bool, crashed the templater — now coerced to string
at load time with a clear error on nulls).
