# PFES-TR-003 — Engineering Media Package (Draft)

An engineering media package may contain:

- primary raw or ISO image;
- `.xdvd.json` and/or `.media.json`;
- AD, PFI, DMI, SS, or other authentication/descriptor resources;
- acquisition log;
- validation report;
- cryptographic hashes;
- provenance record;
- tool and hardware identity;
- emulator-consumption hints.

Not every media family requires every component. Completeness is defined by the engineering questions the package must support.
