…write the final status
Round the total to display precision before splitting into minutes and seconds, via a shared formatTimestamp helper, so 59.96 renders as 1:00.0 instead of 0:60.0. Applies the same rule to the whole-second duration and ETA formatters that rounded the seconds remainder after splitting.
hasCompleteTranslation counted empty-source cues as missing while translationProgressByCode skipped them, so a track with silent cues showed full progress but never counted as complete. Both now use one helper.
…y works The display-adapter class GUID was mistyped, so winreg.OpenKey raised on every Windows host and detect_host_gpus() returned () - silently disabling the 'which GPU is idle and why' report (#2620). The test fake ignored the key path; it now only answers the real one, a repo-wide guard rejects unknown device setup class GUIDs, and why_no_gpu() names the installed graphics on an iGPU-only host instead of blaming the NVIDIA driver.
If graph setup or the first frame schedule threw, the AudioContext was leaked with no stop handle, holding the audio device open. Close it on setup failure and make teardown close it even when a node disconnect throws.
consumeLongformStream only released the reader on abort, so a throwing onEvent handler or a transport error left the body locked and the render connection open. Cancel in a finally unless the stream ended on its own.
spellOut split on code units, tearing emoji and supplementary characters into lone surrogates. Segment by grapheme (falling back to code points).
/v1/audio/speech resolved a voice only by profile UUID, so the name a user sees in the app fell through to an engine preset. An exact id still wins; otherwise a unique case-insensitive name matches, a name shared by several profiles is a 409 ambiguous_voice listing their ids, and OpenAI voice names and 'default' keep their built-in meaning. GET /v1/audio/voices marks which profile names are usable as voice. No schema change.
…tight cues Subtitle cues a frame or two apart left sub-25 ms gap chunks in the background retime graph; ffmpeg's atempo cannot process an input that short and failed the whole batch, so the export answered HTTP 409 (#2616). Short and native-rate chunks are now padded/trimmed to length without atempo, a zero-length cue or its ratio no longer rejects the export, the original track uses the same stream selection as the separated bed, and the concrete cause is logged.
…fails files:saveAudio discarded the failed response body, so users saw only 'Error invoking remote method ... (HTTP 409)' (#2616). Main now carries the status and body across IPC; the renderer rebuilds the same ApiError a direct request produces, so every native save surfaces the localized backend detail and the IPC wrapper is dropped from other save failures. The web dub export reads the error body too.
…2618) For users sharing the GPU with a local LLM or other VRAM-heavy app. When enabled (Settings > Performance & Device > Memory management, or OMNIVOICE_OFFLOAD_AFTER_GENERATION=1; default off), the in-process TTS model moves to system RAM once the GPU pool has been idle for a short grace period, and the next generation moves it back through the existing placement heal (get_model and now the cached OmniVoiceBackend path). Works on CUDA/ROCm, XPU, NPU and MPS; a no-op on CPU. Never offloads while another GPU job is running or queued, or while a dub/batch/audiobook job is active. All model moves share one lock, and a failed restore leaves the model wholly on CPU instead of split across devices.
'Alloy' or ' NOVA ' now maps to the engine default like 'alloy' instead of being forwarded to the engine as a preset name.
NFKC folds full-width Latin and ligature spellings to the same key.
The cap compared UTF-16 length, so multi-byte input could buffer about three times the limit; a line completed inside one chunk is now checked too.

After an offload on Apple Silicon, m.to("mps") also moves audio_tokenizer onto MPS, although OmniVoice.from_pretrained() deliberately keeps it on CPU because its codec does not support MPS. The next generation encodes or decodes audio on MPS and fails. Preserve the codec's CPU placement when restoring the voice model.

Two concurrent macOS dev launches can both pass cacheIsValid() before either publishes its bundle, then the second launch can delete the first launch's newly published bundle with rmSync(). The first launch may already be starting or running Electron from that directory, so it can lose its executable or framework files. Lock cache repair and publication together, then check the cache again inside that lock.

The autouse reset for the shutdown flag and GPU pool lived only in backend/tests/conftest.py, so in tests/ a test that exits the app lifespan (the dub tests) left the process in shutdown mode and the post-generation offload tests that ran after it stood down. Move the fixture to a root conftest.py shared by both suites, add a tests/ guard pair, and make the offload tests reset every module global they read.

- Line 10: Remove the module-level binding of services.model_manager as mm and
resolve the module inside each test in
tests/test_shutdown_state_reset_tests_dir.py using
importlib.import_module("services.model_manager"). Update each test that uses mm
to use its runtime-imported module, avoiding a stale module object after
sys.modules changes.

A batch of reported bugs and two small features, each with a regression test that fails before the fix.
Fixes
atempoon clips too short for it and skip degenerate cues. Desktop saves show the backend's message instead of a bare HTTP status.Added
/v1/audio/speechaccepts a unique, case-insensitive profile name asvoice. Ambiguous names return 409 with the matching ids.Tests
pytest tests: 10,074 passed, plusbackend/tests: 472 passed. The identity-gate and CLA tests also pass, run separately with the local identity hook disabled.locale:check, build, andtest:frontend(107) all pass.This PR fixes GPU detection, export and save handling, concurrency and cancellation races, Unicode processing, timestamp rounding, and other backend and Electron defects. It adds case-insensitive voice-profile name resolution to
/v1/audio/speechand opt-in post-generation TTS offloading to system RAM. Review the model offload and device-restore paths for failures that could affect later generation; full platform validation is not established by the supplied evidence.
