     * Mock Implementation Details
     * ---------------------------
     * This mock always returns true because the test environment uses
     * controlled, synthetic data that never contains real PII.
     *
     * A real implementation should:
     * 1. Scan signal events for PII patterns (emails, names, IPs, etc.)
     * 2. Check that skill_id values don't contain user identifiers
     * 3. Verify context fields don't leak sensitive project paths
     * 4. Ensure keyword_weights don't contain personal identifiers
     * 5. Validate that exported data is properly anonymized
     *
     * The mock skips these checks since test data is constructed with
     * known-safe values (UUIDs, generic skill names, etc.).
     *
     * @returns Promise<boolean> - Always true in mock (no real PII checks)
