State
Current observable condition of a system entity or field.
Architecture
Execute by cause, not by temporal habit.
PNVA-Core models computation as a field of observable state changes that generate events, tension, collapse decisions, restricted execution and proof logs.
Core Chain
state -> event -> tension -> collapse -> execution -> proof
Event
Detectable state change that enters the PNVA field.
Tension
Operational pressure generated by event strength, state gradient, cost and memory.
Collapse
Decision point where tension crosses threshold and action is authorized.
Execution
Restricted action performed only after causal justification.
Proof
Auditable JSON record explaining why the action was taken or ignored.
Formal Direction
Phi(t+1) = Phi(t) + alpha E(t) + beta grad S(t) - gamma C(t) + mu(Phi(t)-Phi(t-1))
