Business Context
An insurance firm is migrating from an older SAS version (HPBOOLRULE) to Viya. Their data schema uses non-standard column names, and the downstream reporting systems expect the old variable naming convention (e.g., _BR_Rule_X_) rather than the new default.

Expected Result
The output table 'legacy_results' is created. Crucially, the columns indicating rule matches must be named '_BR_Rule_1_' instead of '_Rule_1_', satisfying the requirement for the legacy reporting system.
