# Glossary

> Terms used throughout the docs.

**Artifact**
The packaged output of a successful build. A gzip tarball you download or auto-deploy.

**BuildCookRun**
UE's all-in-one packaging command, invoked via `RunUAT.bat`. The thing BuildPixel runs to build your project.

**Build**
One execution of a build setting. Has a status (`pending`, `running`, `complete`, `failed`, `superseded`), a commit, logs, and (on success) an artifact.

**Build setting**
A reusable preset on a project. Defines what to build (platform, buildType, branch), how (UE version), and when (manual / push / scheduled).

**Cooker**
UE's content-processing tool. Converts `.uasset` files into platform-specific cooked content.

**DDC** (Derived Data Cache)
UE's cache of expensive computations: shader compiles, texture compressions, lightmap bakes. BuildPixel preserves DDC between builds for the same project + branch — warm DDC means much faster cooks.

**Engine version**
The UE version a project targets. Read from `.uproject`'s `EngineAssociation`, or overridden on the build setting.

**Organization**
The top-level container in BuildPixel. Holds projects, members, billing, and source control credentials.

**Project**
A connected repo (GitHub) or stream (Perforce), plus its build settings. Lives inside an organization.

**Stream**
Perforce's typed branch model (mainline / development / release / virtual / task).

**Supersession**
When a newer build for the same `(project, branch, platform, buildType)` cancels older in-flight builds. The dashboard hides superseded builds in summary views by default.

**.uproject**
The JSON file that defines an Unreal project. BuildPixel parses it for engine version, modules, and plugin info.
