Each patch is a single logical change and compiles on its own. All three were validated in QEMU on the KASAN kernel: baseline trigger, patched no-trigger or clean rejection, and a normal filesystem mount/write/fsck regression. The baseline source and build were restored and hash-verified after each run.
