Hierarchy

QuollVault uses one containment hierarchy:

Workspace → Project → App → Environment → Build

Workspace owns people, plan and quotas.
Project groups Apps and is a primary authorization scope.
App represents one mobile application.
Environment is a named release lane such as staging or production.
Build is an immutable uploaded artifact plus parsed identity, checksum, provenance and release notes.

IDs are canonical UUIDv4 values. Names are display values and are never authority selectors.

Deleting or archiving parents is lifecycle-guarded; retained Builds are never silently cascaded away.
