From the editor
Verified all claims against source snippets. The previously flagged overreach on intellectual property has been correctly fixed — the body now reads "no evidence that any intellectual property was stolen or compromised," which aligns with source [^5]'s language ("found no evidence that its production systems or intellectual property were compromised") and is further corroborated by sources [^1] and [^3] which state "none of its intellectual property was stolen." All other factual claims check out: the Shai-Hulud/TanStack attribution is supported by [^4] and [^2]/[^5] respectively, scope-of-impact statements are well-sourced, and no fabricated quotes or unsupported claims were detected.
