# CPD exclusions for intentional structural duplication:
# - hash: algorithmic duplication across SHA-256, SHA-512, MD5, etc. and between File/syscall I/O paths
# - cp/dd: shared raw-syscall I/O patterns (splice, copy_file_range, sendfile fallback chains)
# - head: dual read path (buffered vs raw) with similar structure
# - wc: SIMD and scalar counting paths with parallel structure
# - cat: similar buffered/unbuffered output paths
# - fold: ASCII fast path and byte-mode path share structural patterns
# - tail: sendfile + backward-scan patterns shared with head/cat
# - tests: natural structural similarity across test scenarios
