Insert a "cmpunlocker unlock (install)" step after unlock verification:
y/N confirmation (default n) or --unlock runs install.sh from the
harness clone (main branch, ff-only pull first) with live terminal
output and full log to cards/<serial>/install_unlocker.log. On success
the Vulkan stress is skipped until after the cold reboot.
Score now enforces the post-unlock invariant: when verify reports
unlocked-ok, any final link other than Gen2 x16 fails with a red
[ERROR] and exit 1. README safety section and AGENTS.md harness
cloning invariant updated to match.
