The evaluator mapped P95_LATENCY_MS to ExecutionStats.avgDurationMs because stats_1m_route has no p95 column. Exposing the old name implied p95 semantics operators did not get. Rename to AVG_DURATION_MS makes the contract honest. Updated RouteMetric enum (with javadoc), evaluator switch, and admin guide. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
