Knowledge governance

  • Added Knowledge Governance / RAG Governance across the manifesto, website, lifecycle, evidence model, shared agents, and shared skills.

  • Added the RAG Governance Agent and RAG Governance Skill.

Evidence and project quality

  • Extended Test, Deploy, and Operate to cover prompt, RAG, model, tool, and orchestration changes.
  • Added traceability from requirement to knowledge source, agent behavior, test evidence, and release.
