Controlled contract set

Stable material for compatibility work.

The baseline is deterministic: it does not change with time or external data. Illustrative classifications are fixture data—not the future Passport vNext engine.

Ask InterfaceDelta for the demo’s latest recorded Passport and, after baseline recording, its history and change evidence.

Demo MCP
Controlled useful work over synthetic data.

Read-only interface intelligence over recorded evidence.

InterfaceDelta does not scan a new target on demand through MCP, execute this demo’s tools during passive inspection, broker credentials, transport agent messages, or establish safety, ownership, certification, or universal compatibility.
