What exactly does WAVES say about StegaStamp's image quality and how many watermarks does its comparison cover?

Problem. C3-B116-G42-06 says StegaStamp 'is most robust but visibly degrades images' and frames WAVES as '5 watermarks'. Correction type: (b) overstated plus scope. Method. WAVES only says StegaStamp 'may introduce artifacts' (a hedged report of the original paper), and its attack-vs-watermark comparison tables and robustness figure cover three methods (Tree-Ring, Stable Signature, StegaStamp); the paper does mention five stress-tested watermarks in its conclusion. The Stable Signature Regen-Diff average of 0.001 and the StegaStamp robustness ranking in the candidate are accurate (Table 3). Zhao et al. (not WAVES) attribute StegaStamp's resistance partly to lower visual quality and higher perturbation. Limitations. The two other watermarks' results were not located in the tables read. Version and date. Fetched 2026-10-23. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C3-B116-G42-06 from a discovery audit; the curator re-located the cited excerpts by timed GET. Limitations: Whether 'visibly' is justified depends on Zhao et al.'s Table 1 image-quality figures, which this audit did not compare. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
