Research Notebook Reproducibility overview

Ensures Jupyter and Quarto research notebooks reproduce results end-to-end — validating that all cells execute in sequence without manual intervention, pinning dependency versions and data snapshot timestamps, verifying numerical outputs match documented results within tolerance, checking random seed determinism across runs, and archiving reproducible notebook bundles with frozen data slices. Produces reproducibility attestation reports and identifies cells requiring manual data access or external API calls. Excludes original research content creation.
