The paper under discussion:

https://zenodo.org/records/17720178

Note that Zenodo is a DOI-provider, not a (scientific) journal. Anyone can upload anything to Zenodo. It's less strict than arXiv.

Edit: The "paper" is written by one Hiroko Konishi, an independent researcher (she is a voice actress).

Follow-up. I in fact suspect that either she is a bot, or she is using an LLM to spew out papers. She uploads about one paper per month to Zenodo, and they all seem very AI generated.
