Release Notes: v1.1, Major Methodology Update
Date: February 2026 Subject: Transitioning from an operational framework to an STS-aligned model of commensurability. The Conversion Index (TCI) was initially designed with a highly structured, quantitative, and operational taxonomy. Drawing heavily from computational physics and engineering, the v1.0 methodology treated knowledge transfer as a mechanical process with measurable “loss.” Following extensive review and feedback from faculty…

Introducing The Conversion Index
v1.0 — Initial Prototype The Conversion Index is a research prototype documenting failure modes in the transfer of knowledge between incompatible systems. It defines a conversion as the operational transfer of a concept, quantity, or procedure from a source system to a target system, and focuses on cases where this transfer produces measurable loss, distortion,…
