Understand plans, answers, and provenance

Check the plan

The plan is Cassis’s interpretation of the question. Read its assumptions first: “revenue last quarter” may mean booked revenue, calendar quarter, excluding refunds.

When Cassis surfaces a plan for approval, nothing runs until you approve it. Plans without a genuine fork run automatically. If an assumption is wrong, state the correction; you do not need to rewrite the whole question.

Check the answer

Answer

The conclusion and numbers, in the language you used.

SQL

The exact generated statement. On a connected warehouse it produced the rows; on a schema-only project it was not executed and results is null.

Objects used

The tables, joins, and metrics that grounded the answer. An unexpected object is a reason to inspect the result more closely.

Ontology version

The published context the conversation is using. Follow-ups stay in the same conversation and keep that context.

Correct a wrong answer

Rate it down and explain the missing or incorrect rule in the conversation. The correction becomes evidence; recurring evidence is grouped into a detected issue for the data team.

In the web app, Add as test case captures a candidate regression case. A reviewer must validate both the SQL and the business interpretation before it becomes approved truth.
