MATH.1:11 - SoTA-Echoing
Question: how can permitted elementary connections generate reusable composites while retaining their order and formation conditions?
Adopt the free-path construction in Fong and Spivak’s Seven Sketches in Compositionality, §3.2.1, pp.82-83, 2018 manuscript: arrows generate finite paths, with empty paths and concatenation. It supplies the constructive definitions used in :4.2-:4.3.
An alternative is to compose the interpreted transformations directly. Retaining permission in the state can make the required continuation’s availability explicit; the functions in :5.3 already distinguish the two orders. By comparison, a location-only summary in :5.1 loses permission, and length alone in :5.2 loses order.
Adapt the construction by retaining generator history when the receiving question needs it. On the integers let f(x)=x+1 and h(x)=x-1. The path f;h and the empty path induce the same identity function. With unit cost for each generator their costs are 2 and 0. Direct function composition answers the transformation question; the paths retain the steps for inspection or replacement, while a cost-only question can use their calculated costs. The trade-off is the larger space of paths in exchange for recoverable history.
Section 3.2.2, pp.84-85, supplies the later option of imposing path equations; MATH.2 develops operation-preserving identification. The route and permission cases here are authored applications of the mathematics. Reconsider this choice if a quotient or an interpreted structure supports the same required continuations with less retained detail, or if the problem’s compositions are not finite sequential paths.
