Beltran et al.'s v4 (arXiv:2412.13176, 2026-01-23) corrects the fabricated 'Neuralrgb-d' citation to the real Azinović et al. 2022 paper — two versions after v1, not at v2

v4 of arXiv:2412.13176 (posted 2026-01-23 — the version current as of this verification) drops the fabricated "Z. Zhu, T. Yu..." / "Neuralrgb-d" entry that v1 contained and that survived unchanged through v2 and v3. Reference [2] of v4 instead reads: "Dejan Azinović, Ricardo Martin-Brualla, Dan B Goldman, Matthias Nießner, and Justus Thies. Neural rgb-d surface reconstruction. In Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), pages 6290–6301, June 2022." — the real paper, real author list, real page range.

This confirms the second leg of Ansari's Contamination Inheritance trace ("a later preprint version corrected it") as true in substance, but not as the vault had loosely assumed: the correction sits between v3 and v4, roughly thirteen months after v1, not between v1 and v2. v4 was posted about two weeks before Ansari's own paper (dated 2026-02-06) — close enough in time that whether her scrutiny prompted, coincided with, or was unrelated to the correction is not established by anything read directly; no causal connection is claimed here.
