EA 12FEP Codebook for LLM-Assisted Qualitative Analysis

A structured codebook for scoring participant testimony against Längle's 12 Fundamental Existential Prerequisites (12FEP) framework, designed for use with Large Language Models as a research instrument. Built by multi-LLM cross-validation against two primary Längle sources (2002, 2011b). 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. Note: LLMs (ChatGPT, Gemini, Claude) used in the methodology that produced this codebook are research instruments, not co-authors. See README and docs/lineage.md for details.
