1\section*{Authorship, provenance and AI-use disclosure}\label{sec:provenance}2\addcontentsline{toc}{section}{Authorship, provenance and AI-use disclosure}3This working paper develops an exploratory research note dated 28~October 2026 whose listed authors were Simon-Pierre Boucher and ``GPT-6.1'', an AI co-author designation that the researcher asked to preserve; the note is frozen with checksums in the replication package (\texttt{references/initial\_pamle/}). The present version was prepared by the researcher with Claude (Anthropic) acting as a research and programming assistant under his direction: the literature audit, proofs, code, experiments and text were generated in that collaboration and reviewed by the researcher, who bears sole scientific responsibility. The AI systems have no institutional affiliation, e-mail address or ORCID. Most journals do not accept AI systems as authors; for a journal submission the ``GPT-6.1'' designation should be moved from the author list to this disclosure, which is flagged here rather than silently changed. No funding line is claimed for this project.4
