Signal Loss describes three structural states of access a leader operates from under pressure. The Decision Access Self-Check tells you which one you are in right now.
The Self-Check is a short structured diagnostic built on The Decision Access Map™. It is not a quiz and not a lead-capture trick.
Capable leaders do not fail all at once. Under sustained pressure, access to clear decision-making narrows quietly, long before results slip and long before anyone, including the leader, can see it happening.
The book names the mechanism, the sequence through which collapse sustains itself, and the order required for restoration.
