28 Code

This repository is documentation-only — the implementation lives in the private SBFoundation repository. This page is a curated index into the modules most relevant to the research questions here, not a mirror of the code itself.

Module	Relevance to the research
`src/sbfactors`	The factor library — Layer 1 (factor-exposure) of the proposal’s multiplex network; see factor-layer-as-multiplex-layer-1.
`src/sbcrowding`	Comomentum / crowding measurement — the existing single-layer precedent for the proposal’s systemic-risk signal; see systemic-risk-and-crowding-groundwork.
`src/sbriskmodel` / `src/sbfactorrisk`	The factor risk model — correlation structure the network layers build on.
`src/sbic`	Information Coefficient computation — the core “does it predict” test, whitepaper §5.1.
`src/sbpermtest`	Permutation / null testing — whitepaper §5.3.
`src/sbpbo`	Probability of Backtest Overfitting — whitepaper §5.6; the discipline any new network indicator has to survive too.
`src/sbsurvivorship`	Survivorship-bias correction — whitepaper §5.4.
`src/sbcost`	Transaction-cost modeling — whitepaper §5.5.
`src/sbsweep`	Parameter/universe sweep engine — the search infrastructure experiments/ will drive.
`src/sbuniverse`	Point-in-time investable universe construction — see Universe API.
