Outputs

Each video output contains:

• result.json: complete typed result.
• run_manifest.sqlite: run state, stage state, errors, locks, artifacts, and data tables.
• video_summary.xlsx: researcher-facing workbook with a disclaimer and data dictionary.
• report.html: local report.
• tables/*.parquet: columnar tables when pyarrow is installed.
• jsonl/*.jsonl: raw and parsed records.
• sampled frames, crops, masks, audio, caches, validation data, and logs.

Excel cells are sanitized against formula injection, files are written atomically, and the workbook is reopened after creation as a validation step.
