3. Functional testing (KAT)

Each library was checked against the submitted KAT vectors (SHA-256 manifest hash-04/kat.sha256 in the harness) before timing.

5. Resource consumption

Static memory is approximated by the library's loadable ELF segments; peak memory is the process high-water mark (VmHWM) including the benchmark driver and libc, so both are upper-bound proxies rather than isolated algorithm memory.
