3. 3.Run discovery to generate a glossary across every table and column.
4. 4.Promote the pack and discovered terms you care about to Active.
5. 5.Ask a question in chat and save it as a report or watch it as an alert.

Core concepts

• Glossary — an editable dictionary of what each table, column and business term means.
• Semantics — verified join relationships and governed metrics that ground every answer.
• Signals — reviewed, audit-grade records of metric breaches with frozen evidence.
