+### Task 22: Wire whisper-cpp into transcriber factory
+- Added `case "whisper-cpp"` to NewTranscriber() switch on model.AdapterType
+- Imports whisper package to get model path via `whisper.GetModelPath(config.Model)`
+- Creates `NewWhisperCppAdapter(modelPath, config.Language, config.Threads)`
+- Returns error if whisper model ID is unknown
+- Added tests for whisper-cpp factory cases: valid config, no API key required, unknown model error
+- All tests passing, typecheck passes
