Ground answers in approved sources
Create a tiny knowledge set with ownership, dates, permissions, and visible citations.
Grounding is an operating system for sources, not a file upload. Each source needs authority, ownership, access, freshness, deletion, and a citation the reviewer can inspect.
Learning outcomes
What you should be able to show.
- 01Create a source register

Include one stale source, one contradiction, one restricted item, and one question with no answer.
- 03
Inspect retrieval
Confirm the response cites the useful source, identifies conflict, excludes restricted material, and declines the absent answer.
Evidence to keep
Your lesson record.
