The construction is positioned as distinct from prior cyclic or simplicial approaches and is driven by both algebraic and symplectic considerations. The paper also supplies short, self-contained expositions on infinity-categories and the exit-path/constructible-sheaf correspondence that could stand alone as references. Those sections are clear and direct, which is a practical plus for readers who need the background without hunting through longer texts. The Fukaya-categorical discussion is more limited: it openly speculates about moduli of stopped Liouville disks, gluing Fukaya categories, and using multi-ended Lagrangian cobordisms to reach higher K-theory groups. These are framed as possibilities rather than theorems, so they function as motivation and pointers rather than delivered results. No internal contradictions or missing derivation steps appear in the stated claims, and the encoding is presented as a genuine addition rather than a restatement. The paper is aimed at people working at the boundary of higher category theory and symplectic geometry who might want an alternative platform for handling cyclic data or categorical gluing. A reader already comfortable with infinity-categories will get the most out of the new construction; the expository parts widen the audience slightly. It deserves a serious referee because the central construction is concrete enough to be verified or extended, and the intersection area is active.
