Build standalone Sparse and Smatch from recorded revisions, applying the reviewed SCST Smatch frontend correction. Install matching native Smatch data without replacing standalone Sparse or adding project models. Reuse the existing checksum-pinned kernel headers. Record source commits, patch and binary hashes, and installed model contents for CI evidence. Fail preparation instead of silently falling back to different tools; no SCST modules are built or loaded while preparing this image.
