# Two artifacts:
#   lz4_oob_harness   — userspace unit-level proof of the LZ4 OOB primitive
#                       (the same algorithm the kernel uses, compiled with
#                       the same decompression code path).
#   hammer2_trigger.sh — root-run script that builds a crafted HAMMER2
#                        image with a malicious on-disk LZ4 compressed_size
#                        and triggers the in-kernel path via an
#                        unprivileged read.
