**User**: ``` wolfram starts with lambda calculus. make a note about pi calculus and what inverse modeling may mean in the context of this bead. mount-bead acequia-links as I think there's a theoretical basic to links that may have a pi-calculus foundation ``` **Assistant**: *(Tool Call)*: - Identified `acequia-links` as the tie-points bead: `fecb418a-6530-48e0-a6fb-c596c664008e`. - Created a note `2026-06-30-pi-calculus-inverse-modeling-links.md` drawing parallels between Pi-calculus channel mobility and the acequia-links, as well as considering how inverse generative approaches apply to discovering concurrent network topologies. *(Summarized)*: I have authored a note extending the context to Pi-calculus. It mounts the `acequia-links` tie-points bead concept and frames how tie-points might function as mobile Pi-calculus channels, alongside an interpretation of what inverse modeling means when modifying concurrent process rules to generate desired topological target states.
