BLOCK : child killed by SIGSEGV: block-store strcpy's past-the-NUL store crossed the guard page
BLOCK : cbuf allocated at exactly the kernel size (ng_parse.c:1559 has no +1) => equivalent to a kernel heap OOB write
RESULT : overlap/past-NUL reliance CONFIRMED - the in-tree byte-forward strcpy is load-bearing
