## account

One user's balance, plan and status — the thing a charge is made against.

## actor

Whoever a request is acting as: a user, a key, and the scopes that key carries.

## hit

One row the index returned for a query: an entity, its facts, and the score that put it where it is.

## intent

What a query was read as before the index saw it — device targets, formats, size ceilings and kind steers, separated from the subject.

## meter

The running count of what one request cost, charged once when the request finishes.

## rerank

Order a retrieved list with a cross-encoder that reads the query and the candidate together.

## retrieve

Gather candidates from the index for a planned question.

## workbook

An answer packed as something that runs: a notebook, a pinned environment, the model file, an MCP server and a SKILL.md.
