I halted the deployment because pre-production canary runs and stress tests showed unstable output distributions and amplified feedback effects that could increase market volatility in adverse conditions. Model risk controls flagged unresolved issues, including uncalibrated tail-risk behavior, sensitivity to thin-liquidity regimes, and open findings on fairness and consumer-impact metrics. Independent validation and audit sign-offs were not yet complete, and a late-stage dependency patch altered the data ingestion path without full regression coverage, raising operational risk. Pausing deployment preserves financial stability and public trust while we remediate, revalidate, and secure governance approvals.
