New wiki/decisions/appliance-provisioning.md: the hardware-verified step-by-step for provisioning a booth PC (Dell OptiPlex 7070, i5-8500, discrete Nuvoton TPM 2.0) from factory Windows to a hardened Ubuntu 26.04 LTS appliance. Every command was run on the first real unit (2026-06-23). Captures the firmware-specific gotchas: Ventoy → 0x1A under Secure Boot (flash ISO directly); the 7070 BIOS can't view db (verify via live USB); the installer's hardware-backed encryption fails with PCR_UNUSABLE/dbt (use passphrase LUKS + manual systemd-cryptenroll PCR-7 seal); GRUB password must be edit-only (--unrestricted) to keep unattended boot. OS hardening on unit 1 is COMPLETE + verified: LUKS FDE + TPM auto-unlock (PCR 7, unattended) + Secure Boot (Deployed) + GRUB edit-lock (closes the init=/bin/bash root-shell hole that PCR-7 sealing does not cover). Resolves the implementation half of open-questions #12 for unit 1. Cross-linked from disk-os-hardening; index + log updated. Still TODO on the box: Docker + run the stack.
