Witness Vault.
A build-ready $50-$100 physical AI memory proof/custody object: Raspberry Pi Zero 2 W, ATECC608A secure-element sidecar, 0.96 in SSD1306 OLED, optional PN532 NFC, and Bambu X1 Carbon printable enclosure files.
The SanDisk-informed ladder is explicit: Witness Vault is V1 proof/custody, Memory Vault One / Memory Node is the Pi 5 + NVMe locality-cache prototype, and Enterprise Memory Gateway is the governed company policy boundary.
Honest boundary: this raises local custody and witness assurance for Enigma-controlled state. It does not prove events inside closed providers, changes to model weights, truth of memories, physical-compromise resistance, compute advantage, or AI compute acceleration.
