On November 10th 2026 and shortly thereafter, multiple publications ("On Sinks and Mirrors", "Homological Mirror Symmetry for Semi-Truncated Cluster Varieties", and "Functorial Homological Mirror Symmetry for Acyclic Cluster Varieties") are to appear on the arXiV which prove aspects of homological mirror symmetry for acyclic cluster varieties and their generalizations. Here we link an email correspondence providing context for this.
The prehistory of the following chain, at least from the author's perspective, proceeded as follows. In spring of 2026, the (by that time already known to us, see the proposal below) solution to homological mirror symmetry for RFR acyclic cluster varieties was discussed with V. Shende in the context of a similar conjecture for all positroid cells. In early summer of 2026 the author gave a public talk at the Fields Institute on this work, and later in the summer she gave another at the Rutgers Symplectic Summer School on the same topic.
On October 19th of 2026 the author was informed that other parties in the attached chain had prompted ChatGPT Astra, over the weekend and "basically by itself", to solve HMS for RFR acyclic cluster varieties. This initiated the following thread:
