Most coordination failures do not start with a dramatic outage. They start with a quiet absence: an interface exists, work is flowing across it, and nobody can answer the basic questions.

Who owns this boundary on each side?

What does “working” mean?

What are the tolerances?

What happens when reality deviates?

That absence is the Interface Void.

In this episode, Anthony Veltri defines the Interface Void as a structural condition where data and responsibilities cross a seam without stewardship, contracts, or shared definitions. The systems on both sides can be “healthy” and you still get drift, finger pointing, and mission tempo loss because the boundary itself is unmanaged.

You will hear the recognition patterns that reveal the void early: success criteria disagreement, escalation loops, inconsistent refresh rates, silent schema drift, and the classic phrase: “It works on our side.” You will also get the repair moves: named owners on both sides, a dual contract (data plus human), a change notice protocol, and minimum viable behaviors for degraded conditions.

Reflection: If something breaks at the seam tonight, do you already know who responds first, or will you find out through chaos?
