How this one differs
Uses the OAIS from this site: canonical index, lifecycle workflows, bootstrap mode, Tier A/B/C authority. Documentation and agents live in the repo; the OAIS can be cloned and dropped into another product. Emphasizes frequent human in the loopalignment gates and convergence over speed and blind AI trust. Use this OAIS if you are working with an enterprise team or a large project or want a tool-agnostic system.
