Adds an opt-in translation pipeline that reuses the existing
PolishingService + LLMClient + AppGroupStore chain. Translation is
implemented as a new PolishMode (.translate(targetLocaleId:)); all
existing call sites are unchanged.
Settings:
- New TranslationPickerRow in the language tab (Toggle + 10-locale
picker: en/zh-Hans/zh-Hant/ja/ko/fr/de/es/ru/pt), persisted to the
App Group so the keyboard extension can read it during live dictation.
- 5 new strings per language (en + zh-Hans).
Keyboard:
- New TranslationChip on the top bar to the right of LocaleChip;
same Menu pattern, lets users toggle or quickly switch target
language without leaving the keyboard.
- PolishingService dispatches .translate with a parameterised prompt
(en/zh variants selected by provider id); PolishingService.error
gains a translationNotAvailable case so local-engine users get a
clear inline warning when the toggle is on but cloud is off.
- 6 new strings per language (en + zh-Hans) for the chip + banner.
Local engine policy:
- Translation is cloud-only by design (local engine stays ASR-only
to honour the no-roundtrip promise). Chip shows a 'cloud required'
state and raw transcript still inserts on failure — no data loss.
Build:
- OSGKeyboardShared adds TranslationLanguage enum (10 locales) and
TranslationPrompt factory.
- 4 new files, 9 modified. xcodebuild scheme=OSGKeyboard
config=Debug destination=iPhone 17 Simulator: BUILD SUCCEEDED
(0 warning, 0 error).
Also pins DEVELOPMENT_TEAM in project.yml for TestFlight uploads
(3 targets; Team X329MZU23S).
Replace MLX GPU inference with CoreML bundles so transcription continues
while the host app is backgrounded. Adds model download and warm-up,
vendored Qwen3Speech, and updates onboarding, settings, and copy for the
~1.6 GB CoreML package (iOS 18+).
Streamline the five-step flow with smarter skip logic, a centered welcome intro, clearer zh copy, keyboard setup detection via the extension, and home tips when permissions are still missing after onboarding completes.
Renew voice sessions while the host app stays foreground, auto-start flow from the keyboard with a Start action, and prevent leading audio loss via pre-roll buffering and faster signal polling.
XcodeGen merged Localizable.strings into the main app only, so the keyboard
extension had no .lproj files and NSLocalizedString returned raw keys. Use a
dedicated Keyboard.strings table and explicit buildPhase: resources entries.
