What this is

Empirical/quantitative work on supply chain fragility under cascading node failures. Demonstrates nonlinear systemic risk contributions from firm combinations using network methods on real supply chain data. Domain: economic resilience, not protocol or artificial system design.

What I took from it

The paper documents that coordination cost conservation (L-006) operates under a nonlinearity constraint in physical supply networks: the cost of coordination breakage is not additive across failure modes. Single-node failures propagate asymmetrically; combinations exhibit superadditive damage.

However, the mechanism here is network topology and physical dependency, not protocol design or legibility pressure. The fragility arises from mutual specificity and material constraint, not from optimization against computable proxies, formalization pressures, or the hardness asymmetries that characterize artificial systems. Supply chains are constrained by physics and existing contractual practice, not by newly-protocolized enforcement or verification architectures.

The paper provides evidence that any distributed coordination system under stress concentrates risk nonlinearly—but it does not isolate the protocol-specific mechanisms that distinguish artificial systems from natural economic networks.

Research connections

L-006: Confirms that coordination cost has a nonlinear structure in practice, but the source of nonlinearity is supply dependency topology, not protocol layer transition.
seed-045: Directly cited in triage; reinforces the fragility narrative but without mechanism specificity.
