Reduce perceived latency from key release to final text:
- Adaptive chunking: 2.5s first chunk + 5s follow-ups so short
utterances start on-device recognition while still recording.
- Session-level ASR warmup and audio-format cache reuse to remove
per-utterance cold-start of SpeechAnalyzer.
- Mirror live pipelined partials to the keyboard transcript line via
a new flow.transcriptionPartial App Group key + Darwin ping.
Also commits the accumulated custom language model, Flow session,
keyboard extension restructure, and Xiaomi MiMo provider work in
progress on this branch.
Rolls back the v0.2.0 Qwen3 CoreML on-device ASR stack and replaces the
'local engine' UX with iOS 26 SpeechAnalyzer + DictationTranscriber only.
The 'Cloud polish after ASR' toggle (ProviderConfig.localModeCloudPolishEnabled)
lets users opt into a post-ASR DeepSeek round-trip from the local engine.
Defaults to off so the local engine stays genuinely local. New PolishError.missingAPIError
surfaces an inline 'fill in your key' warning when the toggle is on but the
Keychain is empty. DeepSeek preset default model bumped to deepseek-v4-flash.

- Qwen3Speech package declaration in project.yml
- 5 .qwen3ASR enum / branch reference sites in HomeView, OnboardingView,
LocalEngineSettingsRows, FlowSessionManager, ASRService, EngineServiceLabel
- Two pre-existing Swift 6 strict-concurrency errors in
LiveDictationController + FlowSessionManager (the weak [weak self] in
detached-task MainActor.run blocks) that were blocking clean builds
Added:
- LocalModelsGroup: 'Built-in iOS SpeechAnalyzer' badge + 'Cloud polish
after ASR' Switch toggle
- PolishingService: honour localModeCloudPolishEnabled; new .missingAPIKey
error case with localised warning
- AppGroupStore.localModeCloudPolishEnabled (mirrored into App Group
so the keyboard extension honours the toggle during live dictation)
- SettingsView: show provider/api sections when local-mode cloud polish
is on so the user can paste a DeepSeek key
- FlowSessionManager: route through PolishingService for local + polish-on
flow; translate missingAPIKey into a polished warning
- KeyboardViewController: handle PolishingService.PolishError.missingAPIKey
in the keyboard-side live polish path
- CHANGELOG v0.2.1: documents the rollback + new toggle
- README.md / README.zh.md: engine matrix section, data flow note
Verified: xcodebuild -scheme OSGKeyboard -destination 'generic/platform=iOS Simulator'
build succeeds under SWIFT_STRICT_CONCURRENCY=complete.
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+).
Both classes are kept in v0.1.2 (they serve the in-app keyboard
preview and the one-shot host-app dictation handoff path), but
their primary role was taken over by FlowSessionManager +
FlowContinuousCapture in v0.1.1. Add a STATUS section to each
file header explaining the current role and listing the call
sites, so future readers do not assume they are dead code and
try to delete them (which would break PreviewASRController and
KeyboardPreviewSheet).
Refs: AUDIT_APPSTORE.md P0-3
Migrate keyboard dictation to continuous Flow sessions with auto-start,
tap-to-toggle recording, 60s countdown, five-step onboarding, and App Group
IPC. Add docs/ GitHub Pages site with en/zh privacy policy for App Store compliance.
