Model History

Version 1.0 is the first public canonical specification. Future adopted versions will remain accessible here with their exact wording, dates, rationale, and affected records.

First public canon

Canonical Pathogenetic Triad model v1.0

Adopted July 30, 2026First public versionStage-one foundation
Version 1.0 establishes the public model architecture, terminology, formal pathway families, explanatory records, and revision rules. Functional and Clinical Expression is separated from the downstream Clinical Diagnosis, allowing the causal configuration that produces expression to be studied separately from the clinical and institutional processes that produce diagnostic classification.

Included in v1.0

  • The three core components are phenotype-specific trait profile, Cognitive Capacity, and Neurodevelopmental Burden.
  • Functional and Clinical Expression is the integrative outcome of the framework.
  • Clinical Diagnosis is a distinct downstream categorical classification.
  • Five intrinsic causal and developmental pathway families and one Clinical Ascertainment Pathway are specified.
  • Phenotype-formation, burden-formation, and burden–capacity pathways contain atomic relations that can be studied independently.
  • Potential risk factors or exposures are separated from realized neurodevelopmental insults.
  • The permeative environmental layer is distinguished from environmental inputs into burden formation and from ascertainment context.
  • Canonical definitions, scope boundaries, Q&A records, and publication lineage are included in the public foundation.

Scientific status and boundaries

  • Phenotype specificity is located primarily in the phenotype-specific trait profile.
  • Cognitive Capacity and Neurodevelopmental Burden are broadly transdiagnostic.
  • Environmental context is a cross-cutting moderator rather than a fourth triad component.
  • No direct Neurodevelopmental Burden → expression or Neurodevelopmental Burden → trait-profile path is asserted in the canonical figure.
  • The current empirical evidence is preliminary and operationalization-specific.
  • The framework is not validated for individual diagnosis, prognosis, or treatment selection.

Frozen record manifest

The exact records included in v1.0

A canonical release is reproducible only when it identifies the exact revision of every included record. This manifest covers the current definition and mechanism layer. The second-stage release will add postulate, prediction, test, study, evidence, figure, and operationalization records without changing these definitions unless a substantive scientific revision is adopted.

Version architecture

Four histories, kept separate

Scientific model changes, individual record revisions, publication development, and technical website releases answer different questions. Keeping them separate prevents a typographical edit from appearing to be a scientific revision and prevents a new webpage from being mistaken for a new theory version.

01

Canonical model version

v1.0

Freezes the configuration of the complete public scientific model.

02

Record revision

PT-CON-001 · r1

Identifies the exact public revision of one definition, pathway, postulate, or explanatory record.

03

Publication lineage

2019, 2021, 2023, and 2026

Preserves how terminology, hypotheses, and evidence developed in publications and manuscripts.

04

Website release

Technical build

Tracks presentation and software changes without changing the scientific model.

Public version history

No superseded public releases yet

Current: v1.0

When an adopted definition or model change affects scientific meaning, the current wording will remain the default while the exact superseded wording becomes available from the relevant record and release page.

Development of the framework

Publications remain historical sources, not retroactive model releases.

Earlier works show how the framework developed, but they are not retrospectively assigned canonical website version numbers. Their original wording, figures, and claims remain citable on their own terms.

Revision policy

What creates scientific history?

Only reviewed and adopted wording enters the public revision chain. Draft iterations remain private until adopted.
