- domain/subtitle_processor.py: parse_subtitle_file, format_time_range, speed_up_audio, fit_audio_to_duration (moved from audio_buffer), process_subtitle_entries (core TTS loop with cancel/log/progress callbacks) - domain/audio_buffer.py: add fit_audio_to_duration, ffmpeg_time_stretch - domain/output_paths.py: add resolve_unique_path (collision-safe filename) - pyqt/conversion.py: _process_subtitle_file reduced from ~350 to ~100 lines by delegating to domain functions; removed 4 unused subtitle parser imports - +33 tests (8 resolve_unique_path, 14 subtitle_processor, 8 audio_buffer, 3 format_time_range) - 1153 tests pass
