Amazon Bedrock's Automated Reasoning policies now propose their own formal-logic fixes

AWS added automatic policy refinement to Bedrock Guardrails' Automated Reasoning checks: when a test fails, a refinement engine diagnoses it and proposes formal-logic changes for human approval rather than requiring hand-edited rules. Two modes exist — iterative refinement for rule issues (translation succeeds but validation returns unexpected VALID/INVALID/SATISFIABLE/IMPOSSIBLE findings), and ambiguous variable refinement for TRANSLATION_AMBIGUOUS findings caused by overlapping or vague variable descriptions. The async workflow is export → start refinement → poll → retrieve proposed changes → review with test impact → accept or discard; every change requires explicit approval.
