VERDICT: BUG-005 defect CONFIRMED at expression level; end-to-end authorization NOT achieved at this module (defense-in-depth catches the corrupted replica). ============================================================ RESULTS: Total=3, Errors=0 ============================================================ $finish called from file "tb_bug05_fixed.sv", line 143. $finish at simulation time 3000 V C S S i m u l a t i o n R e p o r t Time: 3000 ps CPU Time: 0.140 seconds; Data structure size: 0.0Mb Sun Aug 9 11:04:28 2026
