Product / Discovery
An asset comes back with the definition attached: what it means, what it includes, and which source applies, across every system it touches.
Discovery
A column named "revenue" isn't the definition of revenue. The field comes back with the definition that applies, so the agent knows if it means booked, recognized, or net of refunds.
Retrieved text scored a similarity match, nothing more. The definitions that explain a passage travel with it, so the agent gets what it refers to, not just matching text.
Two tables answer the same question and disagree. One source is marked trusted and the other stale, so the agent doesn't guess between a certified table and an abandoned copy.
