e2e/ drives the web build (vite preview) against a per-worker uvicorn: each Playwright worker boots its own backend on its own port with a temp cwd, so SQLite and audio files are fully isolated and parallel- safe. The page fixture seeds the persisted voicebox-server store with the worker's URL before any script runs. VOICEBOX_FAKE_TTS=1 short-circuits get_tts_backend_for_engine to a backend that synthesizes a sine tone sized to the text — the real task queue, SSE progress, history rows, and audio serving all run, only inference is fake. backend/requirements-ci.txt is the slim dependency set validated to boot the app on a CPU-only runner. Specs: startup, settings layout, seeded profile in /voices, and generate-to-completed-audio through the full pipeline.
