Problem. C3-B139-W28-06 attributes to GeoFlow a flow-magnitude drop (6.9 to 2.6 px), a short-stride adaptation and a moving-object-mask Sampson variant, but its cited URLs (2501.06336, 2504.00983, 2510.21615, 2512.22274) do not contain these figures; 2510.21615 only cites GeoFlow. Method. The figures are in GeoFlow itself, arXiv 2605.18365, which the candidate does not list. Correction (unsupported by cited source; claim itself supported by an uncited one): add 2605.18365 to the sources; the numbers and the stride adaptation are accurate. Limitations. Only the two quoted statements were confirmed. Version. arXiv 2605.18365, current HTML.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C3-B139-W28-06 from a discovery audit; the curator re-located the cited excerpts by timed GET.

Limitations: This is a provenance correction: the numbers are right but sit in a source the candidate does not list.

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