Pre-boot authentication for BitLocker

TPM-only BitLocker is convenient, but convenience is not the same as a proper boundary. BitLocker PINs push that line back to pre-boot, which is where I want it if the machine might be stolen, tampered with, or left somewhere I do not trust.

ecrecover checks for Lixir Vault permit signatures

Chaining logic bugs in Microsoft Edge sandbox escape

Headlamp in-cluster deployment and RBAC boundaries
