/**
 * Deny-Unless-Permit Combining Algorithm
 *
 * This algorithm returns Deny unless at least one policy explicitly permits.
 * It's a very restrictive algorithm that defaults to denial.
 *
 * Decision logic:
 * 1. If any policy permits, return Permit
 * 2. Otherwise, return Deny (regardless of other results)
 *
 * Use case: High-security scenarios where access must be explicitly granted.
 * All other outcomes (Deny, NotApplicable, Indeterminate) result in Deny.
