Algorithms (K)

The K-layer contains reusable, dependency-light algorithms that are shared between:

• measures

• topo_groups

• polymer classification

• mapping/backmapping

• future analysis CLI tools

Key modules (v1)

• Graph views: edge lists and adjacency

• Components / clusters / percolation primitives

• Graph shortest paths

• Graph structural descriptors

• Contact graph builder (placeholder)

• Stats/numerics primitives

• Mapping/backmapping

• Polymer classifier

• Chain ordering utilities

Design contract

Algorithms depend only on:

• :c++:type:GraphView

• :c++:type:GeometryView

• indices (MoleculeIndex/ChainIndex)

They do not depend on Runner, Reader, or IMeasure lifecycles.
