Contact preparedness used to hide inside academic workshops, quiet ministries, and internal lab exercises. It now has vendors, scopes of work, and budget language.
Public institutions and large operators are starting to buy simulation packages for signal quarantine, interpretation delay, reply review, and disclosure choreography. That does not mean anyone expects contact on a given date. It means the topic has crossed the line between abstract concern and operational planning.
The significance is institutional. Once drills become something that can be tendered, audited, and renewed, the protocol question stops belonging only to philosophers and security planners. It becomes part of how infrastructure organizations prove they can govern uncertainty without improvising in public.
