Palash Debnath 43f1d46fe6 fix(indextts): accept the config name upstream ships, and keep long text alive (#1619)
* fix(indextts): accept the config name upstream ships, and keep long text alive

Two independent defects, both reported on a working IndexTTS 2.5 install.

Install always failed. IndexTeam/IndexTTS-2.5 ships the model config as
config.yaml — at the pinned revision d0aa86e7 and at HEAD; config_v2_5.yaml
exists in no upstream revision. VoiceStudio demanded that name, so
_weights_floor_ok never found it and the install died claiming 'the download
was likely interrupted' when the download had been perfect. The only way
through was to hand-rename the file. Both names are accepted now, in the
installer and on the load path, so installs created with the workaround keep
working without a reinstall.

Long text was killed at 60s. infer() is one blocking upstream call that puts
nothing on the wire, and IndexTTS was the only sidecar still on the 60s
recv_timeout_s class default while pockettts and omnivoice-subprocess had both
raised theirs. Raising the default alone does not fix it — which is why the
reporter's RECV_TIMEOUT_S=3600 edit didn't help: progress frames are also what
report activity to the GPU pool's execution clock (#1367), so a silent sidecar
still trips the outer generate budget. The sidecar now heartbeats every 5s
while infer() runs (and during the cold model construction), _send takes a
lock so the beat thread can't interleave framing, and the deadline rises to
900s via OMNIVOICE_INDEXTTS_RECV_TIMEOUT_S.

test_indextts25_health_requires_25_config_name asserted the bug — that a
checkout holding only config.yaml is unhealthy — so it is rewritten to the
corrected contract, including that a genuinely truncated download is still
caught.

Fixes #1611

* test(indextts): follow the installed config name in the sidecar loader tests

Two more tests encoded the config_v2_5.yaml assumption, both asserting
cfg_path against a directory where no config existed at all — so they were
pinning the literal name rather than the resolution. They now lay down a real
checkpoints/ tree and assert the resolved path, including that a checkout
carrying the pre-fix hand-renamed config still resolves.

Caught by the full suite; the targeted runs during development did not reach
tests/backend/services/.

* test(indextts): event-driven heartbeat tests, real interleaving proof, precedence pin

Review round on #1619 — all four findings taken.

- The docs line naming 0.5.1 is version-neutral now ('Earlier installs') —
  version labels are the owner's call.
- The heartbeat tests waited on wall-clock sleeps; they now block on a
  per-write Event with a bounded deadline, so scheduler load can't flake them.
- The _send test asserted the lock EXISTS — a tautology. It now drives four
  concurrent writers through a stream that yields between every byte and
  asserts every frame decodes; verified fail-before by removing the lock
  (torn frame) and pass-after.
- The precedence test deleted config.yaml before creating the renamed one, so
  reversed precedence still passed. Both files now coexist for the assertion;
  verified fail-before by reversing _CFG_NAMES.

Palash DebnathandClaude Fable 5 48c9a3b1f8 feat(settings): compute-device override (auto / CUDA / ROCm / XPU / MPS / CPU) (#1557)
* feat(settings): compute-device override — auto | CUDA | ROCm | XPU | MPS | CPU

Auto-detect stays the default; the override kills the 'auto-detect picked
wrong' issue class. Applied at the single choke point (_probe()'s family
selection) so routing, get_best_device(), and every badge inherit it.
Resolution: OMNIVOICE_DEVICE env > Settings pick (prefs.json) > auto (#981
pattern). An override can steer, never invent hardware: a family the host
lacks is noted and ignored; cpu is always honorable. Applies at next
backend start (host caps are immutable per process — same restart contract
as the rest of the Performance tab, RestartBadge shown).

GET/PUT /api/settings/compute-device (admin-gated) reports resolved vs
applied so the panel shows restart-required truthfully and disables itself
under an env pin instead of pretending.

* docs(changelog): entry for the compute-device override (#1557)

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(device-override): harvest — the override reaches CT2 ASR, full i18n, honest edge states

- _ctranslate2_cuda_ok() and the ASR sidecar now gate on the probe's family,
  so a cpu pin (or ROCm host) can never hand CTranslate2 a CUDA device —
  the override reaches every CT2 loader through one shared gate
- override_ignored exposed by the API and shown by the panel (env pin naming
  a device this machine lacks: auto is in effect, restart won't change it)
- all 8 panel strings + 5 device-family labels translated into all 21
  locales; failed saves keep their error visible through the re-sync
- test isolation: cleanup drops OMNIVOICE_DEVICE before re-probing so no
  overridden caps leak into later tests; panel tests wait for loaded state
- xpu/intel search keywords; oxfmt formatting

* fix(device-override): round 2 — fail-safe probe fallbacks, complete i18n, combined pin state

- a broken capability probe now means CPU everywhere (CT2 gate + ASR
  sidecar) — never a torch-derived guess that would bypass a cpu pin or
  re-open #1529 on ROCm; regression test added
- env-pinned AND not-detected shows both facts in one subtitle
- device_load_failed/perf_save_failed translated into all 21 locales;
  CJK/th/vi/ar strings no longer say literal 'Auto'
- test_ctranslate2_never_gets_cuda_on_a_rocm_build pins the probe family
  (it was order-dependent on the lru_cache before)

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(test): pin the probe family in the faster-whisper OOM-fallback test

Same class as the rocm-build test: it mocked torch but not the probe the
new override gate consults first, so on a cpu-family CI host the CUDA
fallback chain under test was unreachable.

Palash DebnathandClaude Fable 5 9832fbd693 feat(engines): switch engines from anywhere — footer quick switch, workspace chips, shortcuts (#1530)
* feat(engines): add quick switching controls

* docs(changelog): note engine quick switching (#1530)

* fix(support): theme amount cards

* fix(support): restore themed amount cards

* fix(engines): address quick switch review findings

* fix(engines): green the full frontend suite around the quick switch

Three failure classes the targeted runs missed:
- the popover referenced --chrome-radius, which does not exist; it now
  wears the footer's shared MENU_SURFACE like the compute popover
- LogsFooter tests hand-wrote their api/system and api/hooks mocks, which
  drop every export the footer gains next; they are partial mocks now
- DubHeader/AudiobookHero tests rendered without a QueryClientProvider,
  which useEngines needs

Also: workspace-header chips open the popover downward (dropUp stays on
the footer instance) so it cannot clip off the top of the viewport.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(engines): one QueryClient per test module, not per render

CodeRabbit: the inline client made every wrapper render a fresh cache,
so rerender() restarted the /engines query mid-test.

Palash DebnathandClaude Opus 5 41722afe3b refactor(launchpad): quieter, borderless design refresh (#1515)
* refactor(launchpad): quieter, borderless design refresh

The launchpad carried decoration from an earlier direction: icon chips,
corner-hung count badges, a permanently visible filled arrow, uppercase
mono card titles, and a dotted stipple divider — plus a frame that had
been invisible since the app-wide border tokens were zeroed.

Rework it around what the borderless direction actually implies:

- Feature tiles get a whisper-faint surface instead of a dead frame, and
  read as three bands (bare glyph + count / title + arrow / description).
  `--card-hue` is spent sparingly — the glyph at rest, the surface, count
  and arrow only once raised. Titles move to sans sentence case; counts
  are plain tabular numerals. Lift softened 4px -> 2px, coloured glow ->
  neutral shadow, plus an explicit focus ring and a staggered entrance.
- Hero drops the boxed "646" pill and the filled A/B-Compare button for
  quiet type, with a hairline standing in for the separation.
- Section labels trade the dotted stipple for a single fading hairline;
  rows are transparent until hover and reveal "Open" on hover/focus (it
  stays in the DOM, so AT and keyboard always reach it).
- Hero, tiles, recent files, callout and project lists now share one
  1180px column — previously only the top half was capped, so lists ran
  edge-to-edge on a wide display while the deck stayed centred.

Two bugs found and fixed while doing it:

- Buttons that had `border border-solid border-transparent` removed fell
  back to the UA default border and rendered a visible 1px outline. They
  now carry `border-0` explicitly.
- `.lp-animate` used `animation-fill-mode: both`, so after the entrance
  it kept owning `transform` — and animation-origin declarations outrank
  normal ones, which silently killed the card hover lift. Now `backwards`,
  which still holds the from-state through the stagger delay.

Also drops CSS the page has not rendered since #904: the cursor-spotlight
layer, the breath ring, and the per-card waveform strip.

Verified with headless renders at 1600/1280/940 and the empty state.

* fix(dictation): decode Wayland portal signals and show the capture pill

The GlobalShortcuts portal declares Activated/Deactivated as
(o session, s shortcut_id, t timestamp, a{sv} options). We decoded the
timestamp as u32, so zbus rejected every signal with

  Signature mismatch: got `(osta{sv})`, expected `(osua{sv})`

and the press was dropped as an invalid signal. Registration succeeded
and the desktop even reported the bound chord back, so the hotkey looked
wired up while doing nothing at all — on every Wayland compositor, for
the whole life of the feature (#1490). Decode the 64-bit timestamp, and
keep the 32-bit spelling as a fallback so a non-conforming portal
degrades to working rather than to silence.

With presses arriving, the second half of the failure showed: nothing
had shown the widget window since it became a hidden recorder host, so a
capture ran with no pill on screen — and a mic or Accessibility failure
rendered into a window nobody could see. Add show_dictation_pill, which
bottom-centres the capsule on the monitor under the pointer and shows it
without taking focus (Windows keeps SW_SHOWNOACTIVATE so paste still
lands in the user's document), and call it from the widget for every
state but idle. Wayland denies clients their own placement, so the
compositor picks the spot there; the pill still appears.

dispatch_dictation_capture now logs whether a press was emitted or
queued — a press that reaches Rust and produces nothing was otherwise
indistinguishable from one the compositor never delivered.

Tests: portal signals decode at both timestamp widths (the 64-bit case
fails before this change with the exact production error); pill
placement centres, respects a second monitor's origin, and clamps rather
than going off-screen; the widget shows for a state needing the user,
stays hidden while idle, and never shows for a press that arrives while
dictation is disabled.

* chore: sync in-progress workspace changes

Uncommitted work already in the tree, checkpointed so the branch matches
the local machine:

- Remote GPU workers: join-from-the-app flow, one-time secrets, QR join
  codes, a Compute control in the status bar, and the device-list
  Workers panel (#1516)
- Model Catalogue workspace, with Settings pointing at it
- Settings sidebar search and keyboard navigation
- Demo assets for dubbing, dictation and voice design, plus the scripts
  that render them
- Backend: validation-error handling, ASR request-path degradation, and
  the accompanying tests
- CHANGELOG entries for the above and for the Wayland dictation fix

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(tests): follow Engines to the Model Catalogue, and green the sweep

- test_supertonic3 asserted the license gate points at "Settings" while
  the engine now names Model Catalogue → Engines, which is where the
  accept button actually lives. The assertion follows the move; what it
  pins is unchanged — the hint must name a place the user can reach it.
- Carries the CJK allowlist entries for the rendered dub bundle (#1517)
  and the regenerated route snapshot for /workers/agent (#1516), both of
  which this branch inherits from the workspace sync.
- docs/install/linux.md: the dictation capsule is bottom-anchored
  everywhere except Wayland, where the protocol gives applications no
  say in their placement. Documented rather than left as a surprise
  (CodeRabbit).

* ci: stop a flaky dependency fetch from failing green runs

en-core-web-sm resolves to a direct GitHub release URL, and github.com
intermittently answers `http2 error: refused stream before processing
any application logic`. uv's own three retries all land within the same
few seconds and fail together, so the whole job dies on a dependency
that has nothing to do with the change under test — it cost #1518 and
#1517 an otherwise-green run tonight.

Two changes: back off between whole `uv sync` attempts, which is what
actually clears it, and pass --no-sync to the pytest steps. `uv run`
re-resolves the environment before running, so every test step was a
fresh chance to hit the same fetch even though the install step had
already synced — that is exactly how #1518 failed, in the isolated
backend/tests step, with all 5467 tests already passed.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* ci: one retry seam for every uv sync, not just the job that failed last

en-core-web-sm resolves to a direct GitHub *release* URL rather than a
package index, and github.com intermittently answers `http2 error:
refused stream before processing any application logic`. uv's own
retries all land inside the same ~10 seconds and fail together, so a job
dies on a dependency unrelated to the change under test. Tonight that
cost four otherwise-green runs across #1515, #1517 and #1518 — and the
first fix only covered the Tests job, so the next failure simply moved
to Smoke (Linux), which syncs separately.

The fetch is per-job, so the fix has to be per-job: scripts/uv-sync-retry.sh
backs off between whole attempts (15s, 45s, 90s) and every workflow that
syncs now goes through it — ci.yml (tests + the platform matrix),
release.yml, security.yml, evals.yml. It still fails loudly after four
attempts, so a genuinely broken lockfile is not disguised as a flake.

The Tests job also lacked the UV_HTTP_TIMEOUT / UV_HTTP_RETRIES the smoke
matrix has always set, which is part of why it was the one that kept
dying; it has them now.

* test(ci): pin the Intel-Mac contract by intent, not by command spelling

test_ci_verifies_intel_mac_as_the_documented_remote_only_host asserted
the literal line `run: uv sync --extra pockettts`, so routing every sync
through scripts/uv-sync-retry.sh read as a broken Intel-Mac contract. The
contract it exists to protect is that the pockettts extra installs ONLY
on backend_supported legs — which the regex now pins, while leaving how
the sync is invoked free to change.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* ci: keep every uv run out of the resolver, and bound the retry budget

CodeRabbit, #1517:

- `uv run` re-resolves before running, so the smoke suite, the
  worker-artifact tests, the release test run and the eval run were each
  a fresh chance to hit the flaky direct-URL fetch outside the retry
  loop. All of them pass --no-sync now; the environment is already
  synced by the step that owns the retries. security.yml's
  `uv run --with pip-audit` is deliberately left alone — it layers an
  ephemeral package rather than running the project's own tests.
- The retry count multiplied uv's own budget (UV_HTTP_RETRIES=5 with a
  120 s timeout on the smoke matrix). Three attempts and 60 s of total
  backoff outlast the refusals actually observed while staying well
  inside the jobs' timeout-minutes.
- The Intel-Mac contract test pinned the smoke command literally too, so
  --no-sync tripped it exactly like the sync line did. Same fix: assert
  the contract (smoke runs only on backend_supported legs), not its
  spelling.

Palash Debnath bcb547b9f2 fix(engines): a slow venv probe is not a broken venv (#1414) (#1421)
Every subprocess engine confirms a candidate interpreter by spawning it and importing the engine package. For IndexTTS that is 'import indextts.infer_v2', which pulls in torch and transformers — seconds with a warm page cache, tens of seconds on a first run, a spinning disk, a network share, or Windows with real-time AV scanning every DLL.

The bound was 10s (15s for three peers), and elapsing it was treated as a negative: the candidate was discarded exactly as if the import had raised. A working OMNIVOICE_INDEXTTS_DIR install was reported as 'IndexTTS-2 is not installed', or fell through into the lazy bootstrap and reinstalled over a working clone. Only successful resolution was memoised, so every retry re-ran the probe and failed identically — which is why all three reported repro paths look like one bug.

A timeout is the absence of evidence, not evidence of breakage. The probe is now tri-state: yes (imported), no (ran and failed), unproven (did not finish). An unproven candidate is kept as a fallback and used only after every candidate has had its chance, so a wedged user clone cannot shadow a healthy bootstrapped venv. If an unproven venv really is broken it now fails at the sidecar handshake with a real error rather than a confident lie about the install.

Fixed as a class: backend/engines/_venv_probe.py replaces the drifted copy in each of the four bootstraps, and the bound is tunable per engine, defaulting to 60s. Zero and negative values are ignored — an unbounded probe would let one wedged candidate hang engine resolution forever.

Reported with a precise root cause by @OracleNightmare. (#1414)

Palash Debnath a23e69d014 chore: point every repo reference at github.com/debpalash/VoiceStudio (#1394)
The repository was renamed. 724 references across 59 files now point at the new URL — README badges, docs, install guides, the updater's releases API call, CONTRIBUTING, the Colab link and the probe harness. GitHub redirects the old URLs, so nothing was broken in the meantime.

Deliberately NOT renamed, because each breaks something on a user's machine: the Tauri bundle identifier (the path to every existing user's data), /usr/lib/omnivoice-studio and the compose container names, and the published Docker image paths.

The image path needed a code change to STAY still: docker.yml derived it from github.repository, so the next build would have published to ghcr.io/debpalash/voicestudio while Docker Hub, a hardcoded literal, stayed put — everyone pulling the documented GHCR path would have kept receiving the last pre-rename image forever. It is now pinned, with a test that fails if it ever derives from the repo name again.

Also makes the probe's repo-name assertion shape-based: it hardcoded the old name and failed on every PR after the rename while the code it tests worked perfectly.

debpalashandClaude Opus 4.8 6cfef5c0cf fix(routing): warn about an under-provisioned GPU before the job, not after (#1226, #1222)
Two users on 4 GB cards (GTX 1650 Ti, Quadro P2000) ran the `omnivoice`
engine, waited out the full compute budget, and were told the job "was too
heavy for the available compute … most often the GPU is VRAM-starved".

The 300s-vs-372s spread between the two reports is purely text length
(`300 + (len-1200)/40`, so 372s ⇒ ~4080 chars) — one bug, not two. Nothing
about the budget is device-aware, and nothing needs to be: the real defect is
that until the moment it failed, routing showed a clean green "accelerated".
`resolve_routing` matched on GPU *family* only, so a 4 GB card and a 24 GB
card were indistinguishable, and no engine declared a VRAM requirement
anywhere in the repo.

- `TTSBackend.min_vram_gb` — advisory metadata alongside `gpu_compat`. Only
  `omnivoice` declares one (6 GB), derived from the pool's own measured
  per-job budget (`_GPU_VRAM_PER_JOB_GB = 5.0`) plus resident weights.
  Inventing floors for engines with no measured figure would put confident
  numbers in the UI that nothing backs.
- `resolve_routing` takes the floor and emits an accelerated-with-caveat
  reason when the host is below it. Reuses the existing caveat channel, so
  the Settings matrix and the synth-time routing notice surface it with no UI
  change. Advisory, never blocking: drivers page to system RAM, and short
  inputs fit where long ones don't. Kernel-risk still outranks it, and a
  failed VRAM probe (0.0) never guesses.
- `_timeout_guidance` names the actual card and its VRAM, and leads with
  "pick a lighter engine" instead of wording that reads as transient
  contention the user can flush their way out of.

Regression test: tests/test_low_vram_advisory.py (8 of 12 fail before),
including that the 300/372 spread really is just text length.

debpalash 7f4d0ad9df chore(audiobook): correct issue refs to #1208 + changelog entries 2026-07-20 22:16:50 +05:30
debpalashandClaude Opus 4.8 a12a7e7ee1 feat(audiobook): expressive maturity — overrides, emotion, cache opt-out, discoverability (#1210)
Audiobook renders were locked to the model's most deterministic preset (32
steps / 2.0 guidance / model-default temps) with no way to change it, which is
why books sounded flatter than the same voice on the Voice page. Open that up
without changing any default byte-for-byte.

- Production Overrides in the Audiobook tab: position_temperature,
  class_temperature, num_step, guidance_scale, postprocess_output (+ seed),
  reusing the Voice page's panel. Unset reproduces today exactly.
- IndexTTS2 graded emotion (emo_vector / emo_text / emo_alpha) reaches the
  longform path via a typed engine-options object; engines that don't
  understand an option ignore it (no crash across the ~14 backends).
- Cache opt-out ("vary repeated lines") so identical lines can get distinct
  takes; default off keeps the content-addressed replay.
- Markup reference now lists the reaction tags that already work in audiobooks;
  docs/expressive-speech.md corrected so no recipe it names is unreachable.
- Fix AudiobookGenerateBody dropping `language`, so audiobook language
  selection actually reaches the backend.

Every new param is folded into BOTH cache layers (chapter + segment) and the
per-chapter preview, so changing a knob re-renders instead of replaying stale
audio — and an all-default request keeps its old cache key, so existing books
don't re-render. Regression tests: tests/test_audiobook_expressive.py (backward
compat, cache-signature loop, preview/render parity, engine-ignores-unknown,
cache opt-out, emotion reaches engine) + audiobookOverrides.test.jsx.

debpalashandClaude Fable 5 83f943bead fix: bot-review harvest (16 findings) + deterministic style/locale CI + reviewer configs
Harvested and verified every CodeRabbit/Greptile finding from PRs #1175,
#1189, #1192, #1195: 16 real ones fixed (fallback ASR preflight bypass,
VRAM release on stream exit, typed 409 parity, uv env independence,
path-privacy in errors, MCP clone_voice hardening, CaptureWidget WS
guard, test hygiene), 4 refuted with evidence, rest documented as
deliberate design or deferred.

Deterministic CI replaces hand-enforcement: tests/test_changelog_style.py
(quiet one-liner format) and tests/test_locale_parity.py (21-locale
key/placeholder lockstep with a ratchet baseline) — the latter surfaced
and fixes 151 already-broken locale strings. CodeRabbit/Greptile carry
the house rules via .coderabbit.yaml + greptile.json; CLAUDE.md gains
the harvest-before-merge and never-accept-as-is rules.

debpalashandClaude Fable 5 63fd497caf feat: TTS-only first run, platform-curated ASR, guided OS permissions, parakeet-mlx
Only the TTS model (~2.4 GB) is required on first run; ASR models are
per-platform curated picks (curated_on in models.yaml) installed on demand.
Every transcription surface returns a typed asr_model_missing error with a
one-click download CTA instead of silently pulling multi-GB Whisper weights.
Settings -> Models is a grouped, platform-aware catalog. New guided
permissions UX (wizard System Check + Settings -> Permissions + mic
pre-flight) with native mic-state checks and OS settings deep-links. New
parakeet-mlx engine brings Parakeet TDT v3 to Apple Silicon (language-gated
capture preference so multilingual dictation never regresses). Docs:
expressive-speech page, Flush/Unload + CPU-fallback triage, clone-length FAQ.
Hardening: preflight fails open for custom model pins, ROCm curation no
longer inherits NVIDIA picks, Windows mic probe reads the NonPackaged
consent key, CaptureWidget setup race fixed, offline-cache CI simulation
fixes so empty-cache runners stay green.

ff56865cf7 feat(engines): one-click IndexTTS-2 sidecar install from Settings → Engines (#1083)
* feat(engines): one-click IndexTTS-2 sidecar install from Settings → Engines

IndexTTS-2 required four manual terminal steps (git clone, uv venv,
uv pip install -e ., export OMNIVOICE_INDEXTTS_DIR). This turns that into
a guided in-app install:

- backend/services/sidecar_install.py — parametrized sidecar provisioner
  (SidecarSpec/SPECS so future sidecar engines are one entry, not another
  installer). Resumable background job with step-by-step status: disk-space
  preflight (needs-X/have-Y message), source fetch (git clone --depth 1
  primary, GitHub tarball fallback when git is absent/fails), dedicated
  venv via uv (OMNIVOICE_BUNDLED_UV → PATH resolution; transformers<5
  isolation preserved — the parent env is never touched), import-probe
  verification, IndexTeam/IndexTTS-2 weights into <checkout>/checkpoints
  (where the sidecar actually loads from) via snapshot_download with the
  auto-selected/configured HF endpoint + token — no hardcoded
  huggingface.co — and persistence of OMNIVOICE_INDEXTTS_DIR (os.environ
  for immediate use, prefs.json env.* for the next launch). Idempotent:
  partial installs repair, downloads resume, healthy installs (incl. a
  user's own clone) report already_installed and are never touched.
- API: POST /engines/{id}/install starts the job, GET
  /engines/{id}/install/status polls it, DELETE /engines/{id}/install
  removes an app-managed install (loopback-gated; refuses user-managed
  clones). list_backends() gains one_click_install.
- Frontend: Settings → Engines shows an Install button on the IndexTTS2
  row with per-step progress, live log tail, weight-download %, and
  error+remediation; the manual setup snippet is demoted to a collapsed
  "Manual install" fallback. All strings via i18n (en.json).
- OMNIVOICE_INDEXTTS_DIR joins the Settings env-var allowlist
  (single-sourced from the installer SPECS).
- Docs: docs/engines/indextts.md leads with the one-click flow; manual
  steps become the fallback section. CHANGELOG Unreleased entry added.
- Tests: tests/test_sidecar_install.py (24 cases — happy path, disk-space
  fail, git-absent/git-failing tarball fallback, partial-install repair,
  already-installed/running gating, uninstall safety, spec↔bootstrap
  contract, router wiring) + 6 new EngineCompatibilityMatrix RTL cases.
  API route snapshot regenerated.

* fix(engines): harden the sidecar installer — review findings

- Route namespace: /engines/sidecar/{id}/install — a dynamic
  /engines/{id}/install would shadow the literal
  POST /engines/sonitranslate/install (engines router registers first);
  regression-guarded by test_sidecar_routes_never_shadow_literal_engine_routes.
- Weights completion marker: a killed-mid-download multi-shard weights dir
  (config.yaml + plausible shards) no longer passes for healthy; the marker
  is written only after snapshot_download returns, so re-runs resume.
- _run_logged: drain thread + proc.wait(timeout) + POSIX process-group kill
  — a grandchild holding the stdout pipe can no longer hang the step past
  its timeout.
- Job log lock: the status poll's list(deque) copy no longer races the
  worker's appends (RuntimeError under active logging).
- Self-heal: a healthy managed install whose env var was lost (prefs wiped)
  is re-pointed by start_install instead of reported already_installed
  while the engine stays unavailable; legacy bootstrap installs (Probe-2
  venv) are trusted via the engine's own probe.
- Single-sourced uv/venv-layout resolution: engines.indextts.bootstrap now
  delegates _locate_uv/_venv_python_path to services.sidecar_install.
- Frontend: stable poll interval (keyed on the running-id set, not the
  status map), reload on a job that finishes before the first poll,
  re-attach to an in-flight job on remount, i18n'd Install aria-label,
  manual-install <details> auto-opens on failure, snippet block hoisted
  out of the JSX IIFE.
- list_backends: sidecar-installable set hoisted out of the per-engine
  loop; exhaustive-shape registry test updated for one_click_install.
- Tests rebind the live services.sidecar_install module per test (other
  suites purge sys.modules["services"], which made router tests
  order-dependent).

* fix(security): validated tarball fallback + scanner-clean installer

- The pre-filter= extractall fallback (Python < 3.11.4) now extracts
  member-by-member behind the same guards extractall(filter="data")
  enforces — regular files/dirs only, no absolute paths, no ../ escapes,
  resolved-path containment. Kills the new CodeQL py/tarslip (high) and
  Bandit B202 (error) alerts; regression-tested with a malicious tarball
  (test_safe_extract_members_blocks_tar_slip).
- snapshot_download tracks the weights repo's default branch on purpose
  (same policy as every other model download; artifacts are
  checksum-verified by hf_hub) — documented + B615 waived at the call.
- Explanatory comments on the intentional empty-except blocks
  (CodeQL py/empty-except notes).

Verified locally: bandit -ll -ii on the module reports 0 MEDIUM+ findings.

* fix(engines): address Greptile review — Windows tree kill, prefs write race, poll robustness

- _kill_tree: Windows now uses taskkill /F /T so a git/uv helper spawned by
  the timed-out child can't keep writing into the checkout (POSIX already
  killed the process group). Unit-tested with os.name patched to nt.
- core/prefs: mutations (set_/delete) are serialized behind a module lock —
  the installer worker persisting its env.* key concurrently with a Settings
  write could previously drop whichever key saved first (whole-class fix:
  every threaded prefs writer, not just the installer). Fail-before/
  pass-after: tests/test_prefs_thread_safety.py.
- Matrix polling: at most one in-flight status request per engine (an old
  'running' response can no longer land after a newer 'succeeded' and
  restart the poller), and four consecutive poll failures drop the stale
  snapshot instead of showing "Installing…" and hammering a dead backend
  forever.

e816a2c24e fix(settings): make provider/token panels honest — real Test now, gated probes, MCP bindings i18n + confirm (#1064)
HuggingFace token (ApiKeysPanel):
- "Test now" actually re-runs whoami: GET /api/settings/hf-token/state gains
  ?fresh=1 which drops the resolver's 300s validation cache (the invalidate
  hook existed but was never wired to any endpoint), so a fixed network or
  rotated token no longer shows a stale verdict for up to 5 minutes. Plain
  panel mounts keep the cache.
- Initial load renders a "Checking token sources…" placeholder instead of
  flashing a false amber "not set" for all three sources.
- Source rows are now a valid ARIA list (the old role="table" had rows with
  no cells, hiding the status from screen readers).
- Enter in the token input respects the in-flight guard the Save button
  already had (no duplicate POSTs).

LLM Providers:
- Test / Fetch models abort when the implicit save fails, instead of probing
  the previously-stored config and pairing a green "Test ok" badge with a
  save error.
- A failed initial load now offers a Retry button instead of dead-ending
  until the panel remounts.

LLM Skills: the per-skill provider Select carries an accessible name
("Provider for <skill>") instead of announcing as an unlabeled combobox.

MCP voice bindings:
- All user-facing strings go through i18n (the panel was the only Settings
  surface with hardcoded English throughout).
- First-run guidance moved out of per-row hints (which never rendered with
  zero bindings and duplicated per row) into the section header + an
  InfoHint that links to docs/mcp.md; an empty state invites the first add.
- Delete asks for confirmation via the shared askConfirm, disables the row's
  button while in flight, and re-syncs the list even when the DELETE fails
  (a 404 row no longer lingers on screen).
- The add row exposes the optional label the API already accepted (the row
  title rendered b.label without any way to set it); default_engine stays
  MCP-side-only and is documented as such.
- First component test file for the panel (load/empty/add/delete/error/a11y).

Tests: backend fail-before/pass-after for the fresh=1 cache bust; new
frontend coverage for every behavioral change above.

17ae952810 feat(settings): Models & Engines pages — engine identity marks, capability badges, upgrade hints, filter, residency (#1058)
The engine list gains a scannable identity mark per engine (EngineMark),
capability badges (cloning, device routing with reasons, sidecar isolation),
and surfaces available-but-has-advice hints that list_backends previously
dropped (new additive hint field; the ready-with-advice convention). The
model store gains a filter, disk context near downloads, in-memory residency
indicators with safe unload, copyable setup snippets, and actionable
empty/error states. Registry additions are additive only (hint,
supports_cloning with the property-descriptor guard).

80f10289fe feat(asr): ASR engines get the same Settings picker TTS has (env var still wins) (#1026)
Settings → Engines now stacks one pinned Engine Compatibility Matrix per
family (TTS, ASR, LLM) instead of a single TTS-titled table with the other
families tucked behind a low-discoverability tab. The backend select/prefs
path (family="asr" → prefs.asr_backend, env > prefs > auto-detect) already
worked but was unexercised and undocumented — it's now locked by API and
resolution-order tests, and README + the openai-compat-asr doc stop
promising a picker that didn't exist / denying one that now does.

549fa4009f feat(engines): expose MLX-Audio's curated model picker (#981) (#994)
mlx-audio multiplexes 7+ curated models (Kokoro, CSM, Qwen3-TTS, Dia,
Chatterbox, MeloTTS, OuteTTS) behind a single "mlx-audio" backend id, but
MLXAudioBackend resolved its active model ONLY from the
OMNIVOICE_MLX_AUDIO_MODEL env var — invisible to Settings and unreachable
without restarting the packaged app with that var set. A user who
downloaded e.g. Llama-OuteTTS via Settings → Models had no way anywhere
in the UI or API to actually load it; the backend silently kept using
Kokoro.

Fix:
- MLXAudioBackend.__init__ now resolves its model via
  prefs.resolve("mlx_audio_model_id", env=..., default=...), mirroring
  active_backend_id()'s env > prefs > default order exactly.
- get_active_tts_backend()'s switch-detection now also tracks the
  resolved mlx-audio model key, so a model-only change (same backend id)
  invalidates the cached instance and reconstructs it — no app restart
  needed to pick up a different curated model.
- POST /engines/select gained an optional model_id field; for
  family=tts/backend_id=mlx-audio it validates against
  MLXAudioBackend.CURATED_MODELS (or a raw HF repo id, matching the
  class's existing tolerance) and persists it via prefs.
- GET /engines now includes a curated_models roster + active_model_id on
  the mlx-audio entry only.
- Settings → Engines renders a small model dropdown on the mlx-audio row,
  pre-selected to the active model, wired through selectEngine's new
  optional modelId argument.

Regression coverage: prefs resolution + env override, cache invalidation
on model-only switch, /engines/select 400s on an unknown model id and
persists a valid one, curated_models present only on mlx-audio, and a
new EngineCompatibilityMatrix vitest suite for the dropdown.

b6ec4e23f3 fix(engines): snapshot lazy registry keys so /engines can't 500 under concurrency (#940)
* fix(engines): snapshot lazy registry keys so /engines can't 500 under concurrency

`list_backends()` runs in a FastAPI threadpool and iterates the lazy TTS/ASR
registries via `items()` → `__iter__`, which held a *live* `dict.__iter__(self)`
open across each engine's slow `is_available()` probe. Meanwhile the lazy
`__getitem__` resolves a deferred entry by mutating the dict (`self[key] = cls`).
A second concurrent `/engines` request (or any ASR op) materializing the lazy
`faster-whisper-isolated` entry therefore changed the dict size mid-iteration:

    RuntimeError: dictionary changed size during iteration
      asr_backend.py:1729 list_backends → _REGISTRY.items()
      asr_backend.py:1665 __iter__ → for k in dict.__iter__(self)

Both `_LazyRegistry` (TTS) and `_LazyASRRegistry` (ASR) now snapshot their live
keys up front with `list(dict.__iter__(self))` — consumed atomically under the
GIL — so a concurrent lazy insert can no longer trip the iteration. The slow
per-engine probes then run over the snapshot, not the live iterator.

Deterministic fail-before/pass-after regression for both registries:
tests/backend/services/test_lazy_registry_concurrency.py.

5bd8968aea feat(engines): real synthesis "Self-test" + copy-paste setup snippet for opt-in engines (#930)
* feat(engines): real synthesis "Self-test" + copy-paste setup snippet for opt-in engines

Builds on #905's Engines-settings fixes (verified still green: license dialog
mounts, matrix reloads on select, cpu_fallback routing toast, cpu-native →
cpu_only). Two enhancements, no #905 behavior touched.

Real "Self-test" for in-process TTS engines
-------------------------------------------
The existing /engines/{id}/health probe only imports the package and reports
"deps OK" for in-process engines — it never proves the engine can emit audio.
New POST /engines/{id}/selftest runs a *tiny real synthesis* from a fixed short
ASCII phrase and reports ok + duration + sample-rate + sample count, proving the
engine actually produces audio. Guardrails keep it cross-platform-identical and
CPU-cheap: TTS + available + in-process only, bounded wall-clock timeout
(OMNIVOICE_SELFTEST_TIMEOUT_S, default 90s) that returns ok=false/timed_out
instead of hanging the panel, a process-wide lock so a click-storm can't stack
model loads, loopback-gated, and only ever on user click (never on load). The
Compat Matrix gains a "Self-test" button (with cooldown) that renders
"0.82s @ 24 kHz in 820 ms". HF tokens in a synth error are redacted like the
health route. Verified end-to-end: kittentts synthesized 89,200 samples @ 24 kHz.

Copy-paste setup snippet for path-gated opt-in engines
------------------------------------------------------
IndexTTS / MOSS-v1.5 / dots.tts / Confucius4 gate on an OMNIVOICE_*_DIR env var.
list_backends() now emits a single-sourced `setup_snippet` (the exact
`export VAR=/path/...` line) surfaced with a Copy button inside the matrix's
"Why unavailable?" disclosure, so users don't reconstruct it from the docs.

Also tightened the incomplete SelectEngineResponse TS type to include the
routing echo (routing_status/effective_device/routing_reason) the post-select
toast already reads at runtime.

Tests: backend selftest success/subprocess-reject/unavailable/unknown/loopback/
exception-capture/timeout/HF-redaction + setup_snippet shape; frontend self-test
render, timeout marker, subprocess+ASR gating, setup-snippet render. New route
added to the API route snapshot. Full vitest (808) + backend engine/routing/asr/
route-inventory/no-CJK green; lint 0 errors; format + typecheck:ci clean.

* fix(test): allow setup_snippet key in list_backends shape assertion

The engine self-test PR added setup_snippet to each backend entry but only
updated the route-shape test; test_list_backends_shape strict-asserts the key
set. Add setup_snippet there too.

75864a597f fix(dictation): refinement never stalls a final (~51s→≤4s), REST polish parity, real ASR preload reuse (#911)
P0 — Refinement blocked every dictation final with no timeout. With refinement
auto:true and a slow/dead LLM endpoint, maybe_refine ran unbounded and blocked
the final send in all three capture_ws handlers (~51s measured; the pill hung
"Transcribing…" until the widget's 15s fallback fired). Fix the class: a hard,
env-tunable budget (OMNIVOICE_REFINE_TIMEOUT_S, default 4s) via a new
maybe_refine_async — a slow/dead endpoint now falls back to the unrefined (but
polished) text within the budget and can NEVER delay the final beyond it. The
LLM HTTP call is bounded to the same budget so the orphaned worker unwinds
instead of holding a connection for the client's full 45s. Refinement is now
also fully best-effort in the legacy handler (it can't turn a good final into
an error frame).

P1 — REST /transcribe lacked polish parity. capture.py never applied
polish_text, so REST returned raw "…test" while the WS returned "…test."
Apply text_polish.polish_text to `text` and `refined_text` (segments stay raw),
so the widget POST fallback and MCP/CLI callers match the live socket.

P1 — The #888 "instant first dictation" preload was a no-op. The preload called
warmup() only `if hasattr`, but SherpaDictationBackend had none, and the WS
handlers built a FRESH backend per session so a warm singleton wasn't reused.
Add SherpaDictationBackend.warmup() (builds the recognizer) and share one warm
recognizer per model id across sessions (get_sherpa_dictation_backend, same
invalidation + a shared lock as the capture singleton); each session keeps its
own decode stream. First dictation no longer pays the 1.3–2.5s load.

P1 — llm_ready is a lie (feeds the P0). It only means "an endpoint is
configured", so a placeholder key reads as ready. The P0 timeout makes a dead
endpoint harmless; add last_refine_status so RefinementPanel flags a
configured-but-failing LLM and links to LLM Providers → Test.

Regression tests (fail-before/pass-after): slow-LLM WS final arrives < budget;
maybe_refine_async hard timeout + status; REST polish parity + refined_text
polish; warmup builds the recognizer and a second session reuses it; the panel
honesty note. Backend refinement/capture_ws/capture/sherpa suites, CJK + route
inventory gates, full vitest (733), lint (0 errors) and format all green.

83e71c5689 fix(asr): close the #730 residuals — chunked dub wedge shares the guarded reset; repeated timeouts recommend the crash-isolated engine (#895)
Residual A — the chunked dub-stream had a PARALLEL wedge mechanism (its own
ping-loop timeout, its own _reset_pool_on_wedge, a dead-end "Try restarting
the server" message). A wedged chunk now routes through the SAME
run_transcribe_guarded bound+reset as the whole-file paths (#731/#851): the
guard resets the poisoned pool once per wedged attempt (no double-reset on
retry) and the user sees the actionable ASRTimeoutError. The reset logic is
extracted to asr_backend.reset_pool_after_wedge — one shared mechanism, so
the semantics can't drift again. run_transcribe_guarded also gains a
timeout_env param so chunk errors name OMNIVOICE_TRANSCRIBE_CHUNK_TIMEOUT_S
instead of the whole-file knob.

Residual B — the crash-isolated ASR sidecar (#393, faster-whisper-isolated)
is wired as an explicit ESCAPE HATCH, not a default:
- selectable end-to-end: Settings engine list gets an explanatory
  install_hint; honest gpu_compat ("cuda","cpu" — it wraps the same
  CTranslate2 engine as faster-whisper); get_active_asr_backend now hands
  back a process-wide singleton for subprocess-isolated backends (a fresh
  instance per request would leak atexit hooks and respawn the sidecar —
  reloading its model — on every transcribe).
- on the SECOND consecutive guarded timeout-with-reset in one session
  (resets aren't recovering the hang; the wedged thread keeps its VRAM),
  the error the user sees + the log recommend switching to the isolated
  engine in Settings → Engines. Never auto-switched (owner rule: no silent
  behavior divergence); a completed transcribe resets the streak.

Tests (fail-before/pass-after verified against origin/main): wedged-chunk
SSE integration (reset count + actionable error + recommendation surfaces),
consecutive-timeout streak (fires at 2, resets on success, suppressed when
already on the isolated engine), timeout_env parametrization, shared-reset
helper, isolated backend in list_backends with hint + honest availability,
singleton caching, gpu_compat matrix entry. Docs: troubleshooting §14 gains
the chunk knob + escape-hatch guidance.

Closes the residuals tracked on #730.
