Spec deltas

The public sandbox SHALL provide a mock reference demo instance that presents dashboard-like reference behavior backed by deterministic fictional AS/RS state. The demo SHALL be usable without Docker, .env.local, connector credentials, a local SQLite database, or a running reference server.

Any public sandbox surface SHALL be mock-backed, resettable, and clearly labeled as simulated. It SHALL teach protocol flows, API shapes, and reference-instance behavior without collecting real platform credentials or presenting itself as a live owner reference instance. A sandbox route family MAY include both lightweight guided walkthroughs and a mock reference demo instance, but it SHALL keep both distinct from the live /dashboard/** operator surface.

Website routes that expose mock AS/RS behavior for the public sandbox SHALL remain sandbox-prefixed, deterministic, and explicitly demo-only. They SHALL NOT redefine the primary reference contract or become required by the live reference dashboard.
