3. Functional testing (KAT)

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

instance build flags KAT
bag_piglet_128 guide PASS
bag_piglet_256 guide PASS
bag_piglet_384 guide PASS
bag_piglet_512 guide PASS

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.

6. Transmission and storage overhead

External public-key, ciphertext and signature sizes follow the curated performance/external_sizes.csv catalog; secret-key and shared-secret lengths remain API figures. See the size audit for disagreements.

bag_piglet_128 522 16 1027 16
bag_piglet_256 1573 32 3097 32

Symmetric primitives

Survey verdict: ICCS-only — *_using_shake names parse pseudoXOF output; AES-256-CTR dead; DRNG only with -DBAG_PIGLET_KAT

Share of each operation spent in the ICCS placeholder hash functions and in the ICCS DRNG (reference build, measured in the same run with link-time wrappers):

instance operation pseudohash/XOF/sm3 DRNG calls per operation
bag_piglet_128 keygen 54% 0.3% drng 1, pseudoXOF 4
bag_piglet_128 enc 18% 0.6% drng 4, pseudoXOF 5

7. Raw evidence index

Paths are relative to performance/data/arm_1/ in the harness; each JSON file records its commands, environment and trials.
