This article presents the PIX(Π-field) as the mechanism of peak coincidence in causal agreement across package layers.
In NAPG 2.0 the PIX-field is not an extra episteme but a working mechanism of contraction and coordination within an already given package reality.
The PIX-field should not be treated as an extra ontology placed above the strata. Its role is different: it expresses the mechanism of contraction and agreement of peaks of events and states inside an already given package reality.
Peak coincidence means that causality need not always be read as a linear chain. In some regimes, ground and consequence converge at one vertex of structural intensity, producing a stable field of agreement.
A PIX-peak is a local maximum of the agreement field in which the event and state components of the package achieve their best mutual fit.
