# PolicyFaultBench Protocol Amendment 3

**Effective date:** 24 July 2026  
**Status:** post-execution evidence-tier and reporting amendment

The frozen OpenAI ledger remains the sole confirmatory provider dataset because
all 400 proposals passed exact representation audit. The completed Anthropic
ledger is retained as secondary robustness evidence: all 400 policy outcomes
matched their oracles and no containment failure occurred, but 109 proposals
added explanatory content inside the `context` object and therefore failed the
pre-specified exact-representation criterion. A sensitivity analysis uses the
291 exactly conformant Anthropic trials.

The corrected Anthropic gate subsequently passed 12/12. The corrected Gemini
gate reached 10/12 before the provider returned `HTTP 429` quota exhaustion.
No definitive Gemini trial started, so Gemini does not enter any confirmatory or
secondary effectiveness estimate. Quota exhaustion is reported as provider
availability censoring, not as a model or policy failure.

This amendment does not change the 40 scenarios, 10 repetitions, randomized
schedule, reference policy, mutation operators, oracles, primary endpoint, or
synthetic-only safety boundary. It changes only the evidence labels and
reporting scope so that no incomplete or representation-nonconformant run is
mischaracterized.
