Alea v0.11.0-beta

Alea — air-gapped Bitcoin recovery-phrase generator

Reproducible build; source tag and checksums signed; binaries NOT
code-signed. The git tag is SSH-signed and SHA256SUMS.sig signs the
checksum file — verify both against the repository's allowed_signers
key (VERIFYING-MEDIA.md). The .efi binaries themselves carry no
Secure Boot signature (Secure Boot must be disabled to boot them — see
the flashing notes below). Verify what you downloaded against
SHA256SUMS before flashing:

ssh-keygen -Y verify -f allowed_signers \
  -I 312983771+Xerhs@users.noreply.github.com \
  -n file -s SHA256SUMS.sig < SHA256SUMS

Files

• alea-x86_64-usb.img — the flashable USB image (production launcher at
  \EFI\BOOT\BOOTX64.EFI plus the separate verifier at \EFI\ALEA\VERIFY.EFI).
  Write it to a whole USB device with Rufus (DD mode), balenaEtcher, or dd.
• alea-x86_64-unsigned.efi — the production UEFI payload on its own.
• alea-verify.efi — the standalone chain-loaded verifier.
• SHA256SUMS — checksums for the two payload artifacts above.
• SHA256SUMS.sig — SSH signature over SHA256SUMS, verifiable against the repository's allowed_signers key.

Booting on real hardware

• Disable Secure Boot (the payload is unsigned) and boot the USB in UEFI
  mode (not Legacy/CSM).
• Alea deliberately refuses to run under virtualization — it fails the
  local-physical-machine gate — so the full generation ceremony only runs on
  real hardware.

Read SECURITY.md for the threat model and the entropy audit, and README.md
for the full flashing and verification guide.
