We thank Viktor Matovič, our shepherd at PLoP, for feedback that strengthened the paper throughout, and above all for his insistence that patterns be observed rather than asserted, which improved our methodology and ultimately changed the catalogue itself. We thank Souhaila Serbout, Oscar Nierstrasz, and Diomidis Spinellis for feedback and discussions on earlier versions of this work. We are also grateful to the participants of the EuroPLoP focus group, whose discussion sharpened several patterns, from their naming to their relationship with both older, non-LLM patterns and the emerging LLM-gateway infrastructure.
