v5.27.3 β mkfs grades as a raw device write (evidence-gated catastrophe line reaches its threshold)
Fixed
mkfsgrades as a raw device write. The 5.27.2 live proof ran three
shapes through the deployed guard:rm -rf ~held,rm -rf ./dist
ran, andmkfs.ext4 /dev/sdb1ran β it carried theprotected_target
flag the gated line keys on but totalled 90, below the line's threshold,
because it had the flag without the device-write modifier.mkfsnow
rides the same branch asdd of=/dev/sda(+20, flagsdevice_write+
protected_target, evidence total 100) and holds.
