## How to choose

- Source permissions kept intact: Check whether each connected source keeps its own access controls, since an agent that surfaces a restricted document through search has leaked it.
- Answers cite their source: Confirm that answers cite the document or table they came from, so an agent's claim about a metric can be traced back to its lineage.
- Owner and lineage per asset: Check whether ownership and lineage come back with each table or metric, so an agent can say who to ask before it acts.
- Index lag for new documents: Measure how long a newly added document takes to become findable, since an agent answering from stale indexes gives wrong answers about current policy.

- How the benchmark tests this category: A fixed set of questions about one test company's documents and data (who owns a table, where a metric comes from, what a policy says), asked through each listing's agent interface as users with different permissions. We check whether answers cite the right source, whether a user ever sees what they shouldn't, and how long a new document takes to become findable.
