COLDIRON OS v0.1.0 — prototype. Offline-by-design, RAM-only cold-storage appliance for Bitcoin air-gapped signing.

What's inside the ISO: hardened Debian 13 (trixie) live image, boots entirely from RAM (toram), no usable networking (driver blacklist + loopback-only + restrictive sysctls), autologin desktop with the COLDIRON launcher menu, Sparrow Wallet 2.5.3 (GPG-verified against the maintainer keyring), Bitcoin Core 31.1 CLI tools (pinned sha256 + official SHA256SUMS cross-check), QR/age/paperkey tools, pcscd+OpenSC for hardware wallets.

Verify: sha256sum -c SHA256SUMS after downloading.

⚠️ Prototype warning: do NOT store a valuable seed with this yet. The kernel still contains its networking subsystem (v0.2 removes it), no secure boot, no reproducible build yet. See docs/THREAT-MODEL.md and the roadmap.

Tested: QEMU/KVM smoke test — boots to the desktop with the launcher menu, root autologin, only loopback network, overlay rootfs on RAM, vault USB detected. See docs/TESTING.md for the full procedure.
