3. Functional testing (KAT)

Each library was checked against the submitted KAT vectors (SHA-256 manifest sign-31/kat.sha256 in the harness) before timing.

instance	build flags	KAT
`TSUOV_128`	guide	PASS
`TSUOV_256`	guide	PASS
`TSUOV_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.

instance	operation	static: ELF image (bytes)	baseline RSS	peak RSS
`TSUOV_128`	keygen	41693	1712 KiB	1792 KiB
`TSUOV_128`	sign	41693	1720 KiB	1880 KiB
`TSUOV_128`	verify	41693	1776 KiB	1868 KiB

`TSUOV_256`	verify	50789	1900 KiB	1972 KiB
`TSUOV_512`	keygen	166297	1728 KiB	2128 KiB

`TSUOV_512`	verify	166297	2252 KiB	2384 KiB

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.

instance	public key	secret key	signature
`TSUOV_128`	779	32	896
`TSUOV_256`	2170	64	2412
`TSUOV_512`	21319	128	2939

Symmetric primitives

Survey verdict: ICCS-only

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):

`TSUOV_128`	keygen	77%	0.1%	drng 2, pseudoXOF 123
`TSUOV_128`	sign	56%	0.1%	drng 3, pseudoXOF 126, pseudohash 1, sm3hash 1.35

7. Raw evidence index

Paths are relative to performance/data/x86_1/ in the harness; each JSON file records its commands, environment and trials.
