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.
Deleted:
- OSGKeyboard/ThirdParty/Qwen3Speech/ (74 files, ~16k LoC)
- OSGKeyboard/Services/ModelManager.swift (492)
- OSGKeyboard/Services/OnDeviceModelWarmup.swift (197)
- OSGKeyboard/Services/Qwen3ASRService.swift (257)
- OSGKeyboard/Services/ModelDownloadSourcePicker.swift (126)
- OSGKeyboard/Views/OnDeviceModelsView.swift (184)
- OSGKeyboard/Views/DownloadConfirmSheet.swift (96)
- OSGKeyboardShared/Models/OnDeviceModel.swift (140)
- OSGKeyboardShared/Services/OnDeviceModelStatus.swift (104)
- Qwen3ASRServiceProvider registration in OSGKeyboardApp
- 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+).
13 items, 555-line diff, build + 15/15 tests green.
ARCH-A3: Phase.error now carries ErrorKind (micDenied/speechDenied/asr/llm/
appGroupUnavailable/unknown) so the UI can pick icons/copy without parsing
free-form strings. Phase.ErrorKind, Phase, LLMError all Equatable.
ARCH-A4: Every TextField in APISettingsCard gets .keyboardType(.asciiCapable)
to defeat SwiftUI's iOS 18 system-keyboard hand-off that auto-suggests
Chinese/emoji and corrupts API keys / URLs / model names.
ARCH-A5 + DOC-3: PrivacyInfo.xcprivacy audited for honesty. Removed three
declared-but-unused APIs (FileTimestamp / DiskSpace / SystemBootTime) and
added ActiveKeyboards (DDA9.1) to the extension (it actually calls
advanceToNextInputMode in the tap path). Main App now declares only
UserDefaults (CA92.1). CHANGELOG updated.
ARCH-A6: Extracted PermissionManager (mic+speech permission flow, iOS 17
branching) and AppGroupPersistor (App Group load/persist) from the God
Object. KeyboardViewController drops 515 → 459 lines. KeyboardPipelineController
left in-place per risk plan — pressBegan state machine is too race-sensitive
to refactor in this pass.
RED-2: Deleted unused Theme enum (no call sites).
RED-3: Deleted unused cardStyle() alias (no call sites).
RED-7: Single source of truth for LLM timeout — LLMClient.requestTimeout +
LLMClientFactory.defaultRequestTimeout; PolishingService derives timeout from
defaultRequestTimeout+1 instead of hardcoding 15.
RED-8: ASRService.transcribe now emits .capability(onDeviceSupported:) as
first event per session; StatusBadge shows REC ⚠️ when the locale fell
back to cloud. New @Published var onDeviceSupported on State.
TEST-1: testPolishThrowsOnTransportTimeout now actually exercises
cancellation: StubURLProtocol delays response 5s, client.polish is
cancelled via Task.cancel(), test asserts the client throws .cancelled /
.transport / .decoding (was: silently passed).
TEST-2: New testPolisherSkipsNetworkWhenModeOff — PolishingService now
short-circuits when modeId == 'off' and returns trimmed input without
invoking LLMClient (proved via injected CountingLLMClient). Service was
moved to OSGKeyboardShared to be reachable from the test target.
TEST-3: KeyboardState (formerly KeyboardViewController.State) extracted
into OSGKeyboardShared so tests can @testable-import it. 5 phase/mode
tests in new KeyboardStateTests. Typealias preserves the old name.
TEST-4: New OSGKeyboardExtTests target with 6 tests covering State
initial values, phase transitions, structured-error round-trip, mode
switching, and InputMode rawValue round-trip.
