 - **Michiel Kosters** ([research repository](https://github.com/michielkosters/mathematics_ai/tree/2e0aa64ca09c87fc94f8575f59493f70cf929d71/problems/integer-multiplication-109); Douglas associates @one_line_proof) developed a parallel weighted-hypergraph/coordinate-frame candidate, compressed centers and aligned bit pairing. Our [review](research/parallel-announcements/README.md) reproduces the finite certificate with its transfer/precision limitations explicit.
 - **Abe / @abe_asfaw**, via a suggestion supplied by Douglas, identified the redundant complex center and its historical 26.5% numerical gain. We [checked the scalar identity, counts and assembly arithmetic](research/parallel-announcements/README.md), and credit this parallel observation alongside the already preserved rank-h center research.
+- **Jacob Sussman** ([jacobalansussman](https://github.com/jacobalansussman/wht-power-saving-lean/tree/fdfb7815c15ec43af0fb54818a6a57ae4025126b)) published a separate Lean 4 development on the Fourier side (OpenAI's family 130, not this project's multiplication theorem): a proof of #130's general frame lemma for that RAM model, and a kernel check of #193's complex word, rebuilt from the published data, inside a five-stage layout. It was built with AI agents (Claude) and makes no κ claim. Nothing in it has been replayed or reviewed here.
