What this is

An empirical audit method for predicting whether social coordination mechanisms remain functional as agent populations scale from small to large. The work applies a diagnostic framework to language-model agent societies, asking whether mechanisms that work in small groups degrade predictably as population size increases—framed as a cost-containment tool for large-scale simulation studies.

What I took from it

The paper is method-facing: it offers a practical diagnostic (frequency of mechanism activation, information use by agents, mechanism-specific breakpoints) rather than a generative theory of scale failure. It sits squarely in L-010 territory (Coordination Adoption Nonmonotonicity) by documenting that mechanisms work/don't-work at different scales, but it does not argue for a mechanism driving that nonmonotonicity—only observing and predicting it empirically within LLM agent societies.

The connection to L-003 (Formalization Ratchet) is weaker. The paper does not directly examine whether mechanisms fail because informal norms harden into formal rules under scaling pressure; rather it treats mechanism degradation as a technical optimization problem to forecast before expensive runs.

The work is domain-specific enough that generalization beyond agent societies remains unclear. It does not establish whether scale-driven mechanism failure is a feature of protocol systems generally or particular to the information constraints and coordination affordances of LLM-based agents.

Research connections

L-010: Documents that coordination mechanisms degrade at scale, but does not propose a driver (adoption signaling loops, threshold cascades, etc.). Adds empirical support to nonmonotonicity claim without mechanistic depth.
L-003: Tangential. No direct evidence that formalization pressure causes mechanism failure at scale; scaling difficulty treated as separate phenomenon.
seed-070 (Obligate-Coordination-as-Infrastructure-Constraint): The audit method implicitly asks when coordination becomes too costly to sustain. Does not name this as a constraint.

Seed title: Scale-Driven Mechanism Saturation Under Fixed Information Bandwidth

Seed type: motif

Seed text: In agent coordination systems with bounded information-carrying capacity (attention, message slots, observation depth), social mechanisms that depend on frequent agent interaction degrade monotonically as population size grows, independent of protocol redesign, because the per-agent information budget required to sustain the mechanism does not scale. This suggests a hard trade-off between population size and mechanism fidelity that may generalize across any protocol system using finitary information channels under broadcast or gossip constraints. The prediction is that mechanisms will fail not because of cascading abandonment but because individual agents become information-starved.
