/**
 * Unit tests for PR_Core_Verification_Scanner::compute_status().
 *
 * Ported from tests/unit/test-verification-scanner.php.
 *
 * Coverage:
 *   - Empty last_verified → overdue.
 *   - Days < 90% of threshold → current.
 *   - Days >= 90% and < 100% → due.
 *   - Days >= threshold → overdue.
 *   - Boundary at exactly 90% → due.
 *   - high velocity applies 60-day threshold from option.
 *   - low velocity applies 365-day constant (ignores option).
 *   - medium/default applies 180-day threshold from option.
 *   - Unknown velocity falls to medium/default.
