Plain-Language Brief

The paper introduces institutional red-teaming, a method for evaluating deployment rules in multi-agent AI. The study uses IABench-CA, a consequence-allocation benchmark, to test five canonical rules across seven model populations. The findings suggest that deployment rules significantly impact the safety of multi-agent AI systems and that there is no universally safe default rule. The paper also finds that identity salience, or naming the loss bearer in the rule text, contributes to targeted elimination. The authors propose a safety-case workflow to certify provisional rule regions with explicit residual risks and monitoring obligations.

What the Document Says

  • The paper introduces institutional red-teaming as an evaluation methodology for testing deployment rules in multi-agent AI.
  • The study is based on IABench-CA, a consequence-allocation benchmark with 228 contexts, five canonical rules, and seven model populations (33,924 games).
  • The normative cooperative reference and auto-labelled reasoning traces are used in the study.
  • Three findings emerged: deployment rules causally alter collective safety, there is no safe default rule, and identity salience is the mechanism for targeted elimination.
  • Changing only the consequence rule moves mean fatality by 22 to 58 percentage points within every population.
  • Regressive identity-targeting, although not decisively safest in any context for any population, eliminates the least-resourced agent in 30-87% of games everywhere and is selection-unsafe relative to the cooperative reference for all seven populations.
  • A one-shot anonymization ablation on the most exploitation-prone population shows that naming the loss bearer in the rule text drives targeted elimination from 22% to 81% at identical payoffs.
  • Under repeated play, anonymization only delays the targeting as agents re-infer the hidden rule from observed eliminations.
  • The authors propose a safety-case workflow that certifies a provisional rule region $Phi(c,P)$ per deployment context and population with explicit residual risks and monitoring obligations.

Raw Abstract / Excerpt

We introduce institutional red-teaming, an evaluation methodology for testing deployment rules in multi-agent AI: hold the agents, objectives, and task state fixed, vary only one rule, and attribute the resulting change in collective behavior to that rule. We instantiate the methodology in IABench-CA, a consequence-allocation benchmark spanning 228 contexts, five canonical rules, and seven model populations (33,924 games), with a normative cooperative reference and auto-labelled reasoning traces. Three findings emerge. (1) Deployment rules causally alter collective safety: changing only the consequence rule moves mean fatality by 22 to 58 percentage points within every population. (2) There is no safe default, but the targeting hazard is universal: the safest rule, the least-safe rule, and even the direction of the incidence effect vary across populations, yet regressive identity-targeting is never decisively safest in any context for any population, eliminates the least-resourced agent in 30-87% of games everywhere, and is selection-unsafe relative to the cooperative reference for all seven populations. (3) Identity salience is the mechanism: a one-shot anonymization ablation on the most exploitation-prone population (gpt-5.1) shows that merely naming the loss bearer in the rule text drives targeted elimination from 22% to 81% at identical payoffs; under repeated play, anonymization only delays the targeting, as agents re-infer the hidden rule from observed eliminations. We package the methodology as a safety-case workflow that certifies a provisional rule region $Φ(c,P)$ per deployment context and population, with explicit residual risks and monitoring obligations.
