Conformance as a Distribution: Delegation Contracts, Error Budgets, and the Allocation of Evaluation Authority in Use-Based AI Regulation
Organizations: InterWork Alliance, Washington, DC
Abstract
Use-based AI regulation assigns obligations by deployment risk but lacks an evidentiary object to carry them. A benchmark score is a property of a model; conformance of a deployment is a failure rate under a declared distribution of contexts, bounded by a scope and subject to expiry. We take the delegation contract of earlier work (frozen configuration, scoped claim, executable revision rule) and study it under strategic play between a deployer, an auditor, and an enforcement point. We ask whether a declared context mixture can be made truthful; whether an audit can be unbiased against a system that detects evaluation traffic; whether a certification error budget can sustain a long-lived deployment; whether an aggregate audit can support a per-subgroup guarantee; and whether an incident metric that counts system failures but not fallback costs ranks arrangements correctly. For each we give a mechanism and a proposition: a proper-scoring penalty on the declared mixture bounds the excess failure of a best-responding deployer by in the penalty weight; a commit-reveal audit drawn from live traffic is unbiased by construction and grades the evaluator with the same sample; a halving error budget drives certification coverage below while -investing sustains it under a marginal false-certification guarantee; a per-subgroup guarantee costs audit size scaling as in subgroup mass; and any failure-only incident metric prefers withdrawal at every fallback cost, even when total loss ranks the arrangements oppositely. Five preregistered synthetic studies test each claim; no language model or production system is evaluated. Enforcement sits at distribution, capability-access, monetization and risk-transfer choke points, expiry of the conformance record is a standard of care, and conformance-as-a-rate is set against the EU AI Act's static conformity assessment.
Figures & tables
| Attack | Answer | Residual |
|---|---|---|
| Declare a narrow or favourable mixture | Scoring-rule penalty on realized traffic (Prop. 1 ) | Excess failure bounded, not zero; requires traffic observable at the choke point |
| Recognize audit traffic and behave better | Commit-reveal audit from deployment traffic (Prop. 2 ) | Requires ex post adjudication; adjudication must be unobservable at decision time |
| Split one deployment into many to reset budgets | Firm-level budget with weighted allocation (Prop. 3 (iv)) | Requires the enforcement point to know the firm, not only the deployment |
| Gerrymander subgroups | Class-based guarantees with stratified audits (Prop. 4 (iii)) | Cost scales with and ; the class must be fixed ex ante |
| Report incident counts only | Loss metric that includes fallback volume (Prop. 5 ) | Requires fallback cost to be disclosed or estimated |
| Shade the configuration | Immutable digest in the record; runtime guard operated by the platform [ 1 ] | Guard detects declared mismatches only, not unknown assumptions |
