+# LifeAudioSingleTurnStreamingCoT
+
+**Version:** vFinal
+
+A single-turn audio dataset with streaming chain-of-thought reasoning for SFT. 822 active training rows with audio references.
+
+## Schema
+
+Top-level fields: `id, split, modality, turn_type, audio, input, timestamps, streaming, target, taxonomy, quality, source, metadata`
+
+- audio (path, reference, duration_sec, loadability)
+- input (text, instruction, length_bucket)
+- target (reasoning, answer, response)
+- streaming (checkpoints with streaming_reasoning)
+- taxonomy (category, subcategory, difficulty, intent_type)
+
+### Target Format
+```json
+{
+  "reasoning": "Natural language reasoning about the task/input...",
+  "answer": "The actual task output...",
+  "response": "Reasoning: ...\n\nAnswer: ..."
+}
+```
+
+Use `target.response` for SFT training. It includes both reasoning and final answer.
+
+## Quality
+
+| Metric | Value |
+|--------|-------|
+| Active rows | 822 |
+| Train | 685 |
+| Eval | 137 |
+| High quality | 822 |
+| SFT-ready | 100.0% |
+| Target grounded | 100.0% |
+
+## High-Quality Configuration
+
+The `high_quality` config contains a filtered subset of default rows where `quality.sft_ready = true` and `quality.is_high_quality = true`. It is not additional unique data.
+
+## Limitations
+
+- Audio is external reference only (HF URLs). No bundled audio bytes.
+- 
+- Natural-language reasoning is template-generated, not LLM-written.
+- Row counts reflect quality-filtered active splits suitable for direct SFT usage.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+# Load default config
+ds = load_dataset("skyzhou06/LifeAudioSingleTurnStreamingCoT")
+
+# Load high-quality subset
+ds_hq = load_dataset("skyzhou06/LifeAudioSingleTurnStreamingCoT", "high_quality")
+```
