Disposable laptop acceptance

dev/laptop-smoke.py exercises the packaged installer, doctor, ASCII branding, signed runtime updater and offline base recovery in one new UEFI/KVM VM. It accepts only trusted ISO and firmware inputs. It creates a private scratch directory and a new 40 GiB qcow2, copies both firmware files, and retains the disk, serial logs and report.json after success or failure. It never accepts an existing disk or host block device. Run it where QEMU/KVM, Python and OpenSSL are already available; on this development machine that is the normal-user Ubuntu development workspace.

python3 dev/laptop-smoke.py \
  --iso /absolute/path/to/new-hydra.iso \
  --ovmf-code /absolute/path/to/OVMF_CODE.fd \
  --ovmf-vars /absolute/path/to/OVMF_VARS.fd \
  --scratch-parent /tmp

The separate dev/iso-smoke.py whole-disk regression remains required. This harness adds the following real guest operations:

1. Seed fresh GPT with an ESP, foreign data partition and selected root. Record partition GUIDs/boundaries, the complete foreign partition hash, foreign EFI and fallback bytes, and firmware BootOrder. Install Btrfs into /dev/vda3 while retaining /dev/vda1, explicitly register a HydraOS entry, then verify those invariants before the harness deliberately sets BootNext to choose that entry.
2. Boot without ISO, verify the packaged Fastfetch art and doctor, install version 1.0 of a locally created EAPI 8 Portage package, and create a real qcow2 plus profile/data sentinels under HOME. The fixture has no sources or dependencies; emerge --nodeps runs in a private guest network namespace with no interfaces, so it cannot fetch a package.
3. Temporarily pin a disposable TEST public key in that guest and verify signed passive local artifacts through the packaged CLI. Apply and roll back a runtime change, refuse a tampered archive without mutation, SIGKILL a child after an actual runtime replacement, damage the CLI, then invoke the independently installed /usr/bin/hydra-update-recover in a fresh process. Verify exact original runtime bytes, the monotonic replay floor and unchanged VM data. Restore the guest's original public key. The production signing key is never read.
4. Boot live with installed filesystems offline. Record kernel/boot, fixture Portage database, world and owned EFI hashes, then create and list a real Btrfs checkpoint through hydra-system. Boot the installed system, upgrade the fixture to 2.0 through Portage in a private network namespace and modify HOME and world.
5. Boot live again, deliberately damage actual installed kernels and the owned EFI loader, and SIGKILL a real restore after its durable root-retained transition. Resume the same checkpoint through a fresh hydra-system process. Compare exact base, package database, world and EFI hashes and all preserved foreign invariants. Boot without ISO and verify version 1.0, current HOME and unchanged VM disk/profile data. The previous failed root and checkpoint remain on the disposable disk.

The loopback HTTP fixture serves only explicitly named in-memory TEST artifacts and their public key. It exposes no host directory, build tree, private key or credentials. The disposable private key is deleted before the VM boots. This HTTP transport tests offline artifact delivery, not production HTTPS discovery or its redirect policy. Neither runtime nor base recovery receives production signing material or existing VM disks.

Only an actual report.json with status: "passed", input SHA-256 identities and all guest phases establishes acceptance. Source tests verify harness construction, real signatures, narrow sharing, byte comparisons and guest script compilation; they do not prove UEFI, Btrfs, Portage or installed boot. This sequence restores an exact kernel after damage and upgrades a real minimal fixture package; it does not claim an upgrade between two kernel versions. Physical ASUS Wi-Fi, audio, suspend, brightness and refresh-rate checks still require live laptop verification.

Run the focused source checks without booting a VM:

python3 -m unittest tests.test_laptop_smoke
python3 -m py_compile dev/laptop-smoke.py tests/test_laptop_smoke.py
