## Atlas

**Atlas** helps you find relevant studies and inspect their evidence in a source-linked comparison.

## Workspace

**Workspace** is the separate diligence and analysis product. A landscape inside Atlas is not the Workspace product.

## Landscape

A comparison question together with its source/search scope, candidate records, and associated evidence context.

## Comparator candidate

A record surfaced for inspection against the question. Surfacing does not establish clinical equivalence or justify cross-study efficacy ranking.

## Evidence packet

Prepared source evidence associated with selected records, including coverage and limitations.

## Source pack

A governed source capability. Its availability, inclusion in a landscape, and search outcome are separate facts.

## Quarantine

Material kept out of accepted evidence because applicable source, identity, comparison-grain, or other validity checks did not pass.

## Revision

A recorded version of a landscape or output. A successor revision allows work to change while preserving historical context.

## Scenario and asset snapshot

A **scenario** represents a set of model assumptions and outputs. An **asset snapshot** records selected case context in a review artifact. Read [Exports and snapshots](https://docs.phasefolio.com/workspace/exports) for verification limits.
