nx_vesicle.nx

nx_vesicle.nx -- typed payload edge between cells. Biology: vesicles are membrane-bound packets that transport cargo between cells (or between organelles). Nishi vesicle is the inter-cell message primitive: cell A produces a payload, wraps it in a vesicle (with methyl-seal of the originator), sends to cell B; B unwraps + verifies + processes. Per [[feedback-pathway-tropism-block-composition-location-agnostic]]: pathway edges are vesicles. Per Captain Moroni: every inter-cell message carries methyl seal so the receiver knows it's from a substrate-self peer, not a forgery. Composes: nx_cell -- vesicles transit between cells nx_methyl -- vesicle's authenticity proof nx_brane -- receiving brane checks CAP_PEER_MESSAGE nx_pathway -- pathway edges are typed vesicle channels nx_provenance_chain -- vesicle send/recv are transforms
