AAD-50
Zero-trust storage erasure. Hardware-verified data destruction.
AAD-50 is an open-source NVMe sanitization framework that closes a 15-year verification gap in Linux nvme-cli. The standard nvme sanitize command returns immediately after acceptance without confirming the drive actually completed the background erasure. AAD-50 fixes this by polling NVMe Log Page 0x81 (Sanitize Status) after every cycle and refusing to advance until SSTAT=0x1 confirms hardware completion.
Implements a 50-cycle B→C→A phase matrix: 40 cycles NAND overwrite, 5 FTL block erase, 5 crypto key destruction. Generates a SHA-256 audit chain and PDF Certificate of Destruction aligned with NIST SP 800-88 Rev.2 Purge and IEEE 2883.1-2025.
