Discovery citations resolve at four levels — the whole Discovery, a *column*, a *row*, or a single *cell* — and Libra is told to always cite the most specific one, so *"why is row 3's job title Innovation Manager?"* lands on that cell.
## Before you start
You need a chat inside a project you have edit rights on: a Discovery created from chat is created in that project, and Libra builds it from **all documents currently attached to the chat**. Attach the documents you want as rows before you send, and remember that each row is one document — Libra reads them independently of one another, not as a single set.
## Create a Discovery from chat
Pick **Tools → Create new → Discovery** to commit to building one, or simply describe the extraction you want. The difference matters: with creation mode armed, Libra has to create a Discovery in that turn. Left unarmed, Libra decides for itself, and proposes a Discovery when a request amounts to asking the same questions of several documents rather than answering inline.
Editing from chat changes the saved Discovery, not just this conversation. Switching a column's answer type re-extracts that column, so the answers already in it are replaced.
## Reference a finished Discovery in chat
Once a Discovery has finished running, attach it to any chat as context and ask follow-up questions. Only completed Discoveries can be read this way — one still processing won't appear in the picker. Libra answers with citations that point at the Discovery as a whole, or at a specific column, row or cell.
