Package Items

Documentation status: guide — see Maturity and evidence.

A package item connects a declared artifact to the package assembly chain. It should make loading explicit rather than rely on editor state.

Use package items to

• include model artifacts deliberately;
• keep package ownership visible;
• control assembly order where the supported manifest format requires it;
• make missing or duplicate identifiers diagnosable during build/validation.

Do not assume that a file present in the workspace is part of the running application. The manifest/package chain is the source of truth.
