The Pain Kernel Framework (PKF) A Canonical Hub for Identity, Origin, Definition, Positioning, and Structural Architecture (Version 1.1)

The Pain Kernel Framework (PKF) is an original conceptual framework that defines human pain as a set of kernel-level processing domains operating prior to meaning-making, diagnosis, or ethical judgment. While multiple applied and exploratory works related to PKF have been previously archived, no single document has unified its identity, conceptual origin, canonical definition, structural architecture, positional coordinates, and scope. This manuscript serves as the canonical hub of the Pain Kernel Framework. Version 1.1 expands the original canonical formulation by (1) explicitly positioning PKF among existing biomedical, narrative, trauma, and ethical frameworks; (2) defining PKF as a translational interface between lived human experience and formal interpretive systems; and (3) clarifying its scope and non-scope to prevent conceptual overextension. PKF is not a diagnostic, therapeutic, or ethical system. It is a pre-interpretive substrate that enables coherent translation across clinical medicine, narrative understanding, and human-centered artificial intelligence.
