A clean rollout has all required assets and end-to-end predictions match the offline fixture set. This is evidence for a different corrective change: Include tokenizer and preprocessing assets with the versioned model package or approved immutable artifact references. That other change addresses: A pre-production model depends on a local tokenizer directory that was not included in the serving container and fails on startup. It does not validate the specific Silverline Insurance remediation for: A streaming search team wants to compare two ranking models but sends them different customer cohorts and treats the results as a fair A/B test. The necessary check instead is: Assignment balance and event-attribution checks pass before interpreting model-version outcome differences.

Warm-request latency meets its target and load events no longer trigger weight reload for each prediction.
