EA 4FM Codebook for LLM-Assisted Qualitative Analysis

A structured codebook for scoring participant testimony against Längle's Four Fundamental Motivations (4FM) framework, designed for use with Large Language Models as a research instrument. Built by multi-LLM cross-validation across three LLMs (Claude Sonnet 4.5, ChatGPT 5 Thinking, Gemini 2.5 Turbo) against four primary Längle sources (1992, 2002, 2003, 2011). Every code traces to a verbatim quote with citation. Companion to the WCET4 (2026) paper "Do You Understand?! Best Practices using Artificial Intelligence in Research (and Life)" by Graham Nelson-Zutter. Related artifact: the EA 12FEP Codebook extends this 4FM framework to 12 Fundamental Existential Prerequisites. Note: LLMs (Claude, ChatGPT, Gemini) used in the methodology that produced this codebook are research instruments, not co-authors. See README and docs/lineage.md for details.
