Wait for the running task to leave the client's book.

`lead_s` of silence, then `speech_s` of loud tone.

Create a symlink, skipping the test where the OS forbids it (Windows without Developer Mode). CI's full pytest run is Linux, so coverage holds.

Replace speaker_id based on a pyannote diarization result (overlap-weighted).

Durably publish one verified input without replacing prior bytes.

Return the times (s) of every speech-like onset across the whole track. Powers the timeline editor's snap-to-onset ticks (issue #280, item 3):

Per-segment clone references (Wave 3.2 / Spec 4). Cut each segment's own slice from the isolated vocals at THAT segment's timestamps, so the

A dedicated-VRAM host (CUDA) with a loaded TTS model.

A routing reason made safe for an HTTP header value: scrubbed, then ASCII-sanitized (headers are latin-1; a non-ASCII device name would 500 the

Error-kind builder the dictation widget switches on. Kinds are a plain string prefix ("a11y:" | "clipboard:" | "paste:" | "preflight:") so the JS side

Renew an attempt's lease from a progress frame. The single entry point for the lease, ceiling included — the transport passes the fla

Commit a result. Returns ``(committed, task)``. The caller must acknowledge the worker in BOTH cases — a duplicate still needs its ac

Speaker-aware re-split using inline ASR speaker turns (FunASR cam++). ``speaker`` is used verbatim (FunASR already labels ``"Speaker N"``), match

Unique scratch dir under the OS temp dir for the #314 venv-validity tests. Caller removes it at the end of the test.

Release the model from memory.

Block until the control plane has activated this worker. `start()` returns as soon as the connection is scheduled, so a join that the

Resolve app code at test runtime; sys.modules-isolating tests may reload it.

Build a whisper-style result from (text, start, end) tuples.

Resolve a persisted job artifact inside the global dub-data boundary.

Return an async callable that mimics the ffmpeg invocation.

``e`` rewritten with engine context when it's a language rejection. Returns ``e`` unchanged otherwise, so this is safe to wrap any failure in.

Run the shared classifier and return the RuntimeError it produces.

Sibling helper for the one in-tree ``sf.write`` site. ``soundfile`` is a different library than ``torchaudio`` — numpy arrays instead of tens

Launch the sidecar if not already running. Blocks on the ready handshake. Caller must hold self._lock.

Stand in for the input-staging step: a file inside the artifact store.

The *live* services.tts_backend (same rationale as test_clone_prompt_wiring._tb: other suites purge services.* modules).

Run-time resolve (see test_generate_engine.py for the rationale).

Resolve services.tts_backend at RUN time, not import time. Pytest imports every test module during collection, but tests/backend/** (which ru

Resolve the video retime plan for ``lang_code`` across both keyspaces. Returns ``(kind, entry)`` where kind is ``"stretch_video"`` (legacy Mo

Resolve a DB-stored audio filename strictly inside VOICES_DIR. Rejects anything that isn't a bare filename or that escapes the voices directo

Human-readable (English) fallback message for the typed payload — what legacy clients / logs see; the frontend renders its own i18n copy.

Build the ``manifest.json`` object for a profile row. Mirrors the legacy ``_bundle_metadata`` persona fields, adds the format discriminator, licen

Idempotently ensure the base tables + additive columns exist. A runtime self-heal for a DB that somehow missed init — e.g. a write hitting ``

Root that holds the managed Python project (`<root>/project/.venv`). Single source of truth for bootstrap + clean-retry + backend spawn.

Expand a per-segment plan into contiguous (start, end, ratio) chunks. Gaps between plan entries — and the pre-roll / tail — are emitted at 1.

Release cached GPU memory on any accelerator (CUDA, MPS, XPU).

Synthesize `text`. Returns a tensor of shape (1, n_samples). When `description` is provided and `ref_audio` is None, engines that sup

Send ping, expect pong. Spawns the sidecar if needed. Returns (True, "pong") on success, (False, "<exc>") on any failure. Never raise
