Schema

Each JSONL record in metadata/ contains the following fields:

• id: unique sample identifier.
• split: dataset split (train, val, test).
• domain: one of finance, medical, or iiot.
• video: relative path to the MP4 file.
• audio: relative path to the WAV file.
• frame_preview: relative path to a representative PNG frame.
• duration_sec: clip duration in seconds.
• fps: video frame rate.
• sample_rate: audio sampling rate.
• task_type: benchmark task family.
• question: generated question.
• ground_truth: deterministic answer.
• has_conflict: whether a counterfactual cross-modal conflict was injected.
• source_mode: substrate source (synthetic or yfinance for finance in the full generator).
• seed: random seed used by procedural generation.
• metadata_file: relative pointer to the split metadata file.
• qa_file: relative pointer to the split QA file.
• algorithmic_metadata: domain-specific gradients and trigger values used by the state machine.

The qa/ JSONL files mirror the QA-specific subset of this information.
