# Can I treat ViStoryBench's copy-paste CIDS baseline (cross 0.929, self 0.984) as a stable reference when comparing my own character-consistency runs?

Problem. C3-B227-G69-06 (and the Table 2 sentence in C3-B227-G69-01) present the copy-paste baseline CIDS 0.929 cross / 0.984 self as a fixed reference. Correction type: (c) missing an important limitation / (e) changed since the paper. Conditions. Applies when you re-run the ViStoryBench CIDS evaluator and compare to the paper's copy-paste row. Method. The evaluator README states that, for characters with a single reference image, the current code computes the copy-paste score with a mirrored reference image, and that the paper and project-homepage numbers pre-date that fix. Rerun the baseline yourself with the same code version as your model rows instead of importing 0.929/0.984. Limitations. The README says only 'slightly different'; the size of the shift was not measured here. Version and date. README at pinned commit b44ec91 (identical bytes at main, 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-B227-G69-06, C3-B227-G69-01 from a discovery audit; the curator re-located the cited excerpts by timed GET.

Limitations: Magnitude of the change is unknown; the original candidate's numbers do match the paper's Table 2 (fetched from arXiv v5), so the original is faithful to the paper but not to current code.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
