Methodology Note 01 v4.0 — Amendment to the Pre-Registration (DOI 10.5281/zenodo.20125967) of the Marin T. Kael Citation-Fidelity Research Programme. v4.0 is an infrastructure migration, not a methodological reformulation. The score-algorithm, question-set, and aggregation logic are byte-identical to v3.0 (DOI 10.5281/zenodo.20262362): 27 of 27 historical datapoints match 1:1 between the v3.0 worker-JS implementation and the v4.0 Python implementation. What changed: the measurement instrument moved from in-Worker JavaScript score-functions to a standalone Python package on top of EleutherAI lm-evaluation-harness v0.4.12. The harness is now reproducible on any researcher's laptop in under five minutes with pinned tooling versions and a public GitHub repository. Change-Discipline (locked): patch (v4.0.x) = bug-fix without methodological impact, no Amendment DOI; minor (v4.1) = additive change (new NEGATIVE_HALLU pattern, new model adapter), Amendment DOI required, task stays marin_research_v1; major (v5.0) = breaking change (new question, score-formula shift, anchor redefinition), new task marin_research_v2, full Pre-Registration Amendment, all post-v4 data treated as separate cohort. The accompanying implementation (lm-evaluation-harness tooling, custom model adapters, CI cron, snapshot-to-D1 push) is published as software v0.4.2 (DOI 10.5281/zenodo.20364157).
