# kernel lane red-proof 2026-10-07T13:08:35Z — each mutation must turn its test red (FAILED); the clean tree is green
clean: OK
no default pin before the install -> test_installing_a_kernel_does_not_change_the_grub_default: FAILED (failures=1)
no boot-setup check -> test_a_box_without_the_esp_flag_is_refused: FAILED (failures=1)
reboot without the flag check -> test_a_reboot_without_the_flag_is_refused: FAILED (failures=1)
no signed-set image check -> test_a_kernel_outside_the_approved_set_is_refused: FAILED (failures=1)   (re-run after the test was sharpened: the first run stayed green because a second image was ALSO refused by the one-kernel rule)
no expect_kver check -> test_a_kernel_outside_the_approved_set_is_refused: FAILED (failures=1)
snippet sets the default before clearing the flag -> test_the_snippet_clears_the_flag_on_use: FAILED (errors=1)
no crash-guard check -> test_the_crash_guard_must_be_armed_and_quiet: FAILED (failures=1)
self-revert used twice -> test_one_self_revert_then_never_again: FAILED (failures=1)
guard trips one unclean boot early (LIMIT-2) -> KernelStepCannotLeaveTheBoxOff.test_planned_reboot_one_crash_one_self_revert: FAILED (failures=1)
