 Historical configuration fields for reviewer timeouts, file-split thresholds, same-role instances, retries, concurrency, and queue behavior remain readable so stored sessions can recover honestly. New adaptive manifests override split, same-role, retry, concurrency, and call values to the bounded policy above. Configured review agents must be file-backed and read-only. `DeepReview` and `ReviewFixer` remain disallowed.
