/**
 * VlocityOpenInterface2 implementation skeleton.
 * Use when the Industries extension point requires the legacy Open Interface contract.
 *
 * Key rules:
 * - Write results into outputMap via putAll(); do NOT return the envelope from invokeMethod
 * - Return true for success, false for unsupported/failed actions
 * - Delegate to the same private methods as the Callable (same inputMap, options signature)
 * - Populate outputMap with the same envelope shape (success, data, errors)
 *
 * Replace Industries_XxxOpenInterface and actionOne with the actual class/action names.
