## Completed

### Task 1: Create language package with core types and helpers
- Created `internal/language/language.go` with Language struct, Auto constant
- Implemented FromCode, List, Codes, AllLanguageCodes, IsValidCode
- Full 57 language list from OpenAI Whisper
- All tests passing, typecheck passes

### Task 8: Migrate OpenAI provider to new Model structure
- Added gpt-4o-transcribe and gpt-4o-mini-transcribe transcription models
- Removed gpt-4-turbo and gpt-3.5-turbo LLM models (not in PRD)
- OpenAI now has 5 models: 3 transcription (whisper-1, gpt-4o-transcribe, gpt-4o-mini-transcribe) + 2 LLM (gpt-4o-mini, gpt-4o)
- All models have AdapterType='openai', Endpoint with BaseURL='https://api.openai.com'
- All models use language.AllLanguageCodes() for SupportedLanguages (57 languages)
- Updated provider_test.go to expect 3 transcription and 2 LLM models
- All tests passing, typecheck passes


### Task 3: Create Model type with full metadata
- Created `internal/provider/model.go`
- ModelType enum: Transcription, LLM
- Model struct: ID, Name, Description, Type, Streaming, Local, AdapterType, SupportedLanguages, Endpoint, LocalInfo
- EndpointConfig: BaseURL, Path
- LocalModelInfo: Filename, Size, DownloadURL
- Helper methods: NeedsDownload(), IsStreaming(), SupportsLanguage(code), SupportsAllLanguages()
- SupportsLanguage("") always returns true (auto always allowed)
- All tests passing, typecheck passes

### Task 4: Refactor Provider interface to return Models
- Updated `internal/provider/provider.go` Provider interface
- Replaced old methods with: Models() []Model, DefaultModel(t ModelType) string, IsLocal() bool
- Added package-level helpers:
  - GetModel(providerName, modelID string) (*Model, error)
  - ModelsOfType(p Provider, t ModelType) []Model
  - FindModelByID(modelID string) (*Model, Provider, error)
  - ModelsForLanguage(p Provider, t ModelType, langCode string) []Model
  - ValidateModelLanguage(providerName, modelID, langCode string) error
- Updated all providers (openai, groq, mistral, elevenlabs) with full Model metadata
- Updated TUI files to use ModelsOfType instead of old SupportsTranscription/SupportsLLM
- Added comprehensive tests for all new helper functions
- All tests passing, typecheck passes

### Task 5: Define BatchAdapter and StreamingAdapter interfaces
- Renamed `TranscriptionAdapter` to `BatchAdapter` in transcriber.go
- Updated all adapters (openai, groq, mistral, elevenlabs) to reference BatchAdapter in comments
- Updated SimpleTranscriber to use BatchAdapter
- Updated test mocks (MockTranscriptionAdapter -> MockBatchAdapter)
- Created `internal/transcriber/streaming.go` with:
  - `TranscriptionResult` struct: Text, IsFinal, Error fields
  - `StreamingAdapter` interface: Start, SendChunk, Results, Close methods
- All tests passing, typecheck passes

### Task 6: Create StreamingTranscriber wrapper
- Created `internal/transcriber/streaming_transcriber.go`
- StreamingTranscriber struct with: adapter, language, finalText builder, mutex, ctx/cancel, WaitGroup
- Start() creates cancelable context, starts adapter, spawns 2 goroutines
- Goroutine 1: reads frames from channel, calls adapter.SendChunk()
- Goroutine 2: reads from adapter.Results(), accumulates final results with space separator
- Stop() cancels context, waits for goroutines, closes adapter
- GetFinalTranscription() returns accumulated text with mutex protection
- Added MockStreamingAdapter and comprehensive tests
- Tests verify: start/stop, result accumulation, partial result filtering, error handling, concurrent access
- All tests passing with -race flag, typecheck passes

### Task 7: Write tests for Model, Provider, and interfaces
- Created `internal/provider/model_test.go`
- TestModel_NeedsDownload: local with LocalInfo = true, cloud = false, nil = false
- TestModel_IsStreaming: returns Streaming field value
- TestModel_SupportsLanguage: multilingual supports all, english-only supports en, auto always true
- TestModel_SupportsAllLanguages: true when 57 languages, false otherwise
- TestModelType_Constants: Transcription=0, LLM=1
- TestEndpointConfig_Fields, TestLocalModelInfo_Fields: struct fields accessible
- TestModel_AllFields: comprehensive struct field test
- provider_test.go already had GetModel, ModelsOfType, FindModelByID, ModelsForLanguage, ValidateModelLanguage tests
- All tests passing, typecheck passes
