PROTOCALL / LEGAL & SAFETY

Clear boundaries before the first packet.

The short version: use ProtoCall only where you have permission, keep live OT testing within an assessed change window, and do not treat a diagnostic result as a safety decision.

Publisher and contact

ProtoCall is published by Armand de Beer. Vextral Systems and ProtoCall are project and product names, not separate contracting entities. Contact info@vextralsystems.com.
