Start at PartialSQLRouteExecutor#route and trace the provided flow through ShadowSQLRouter#decorateRouteContext, AbstractShadowDMLStatementRouteEngine#route, and ShadowRouteEngine#decorateRouteContext. Reproduce the behavior with the supplied Spring Boot, sharding, and shadow-rule configuration, then determine where the shadow route diverges from the configured data sources and table. Done means the reported shadow-rule error is explained and corrected with a regression check.
