Provenance Record

Well-structured Briefing-grade News piece (589 words). Clear chronology (1986 KPZ, 2015 Diehl theory, 2022 1D Paris confirmation, 2026 2D Würzburg result), accurate technical framing, neutral tone.

Read source-0 (ScienceDaily, 200 OK), source-2 (SciTechDaily, 200 OK), source-3 (arXiv 2506.15521, 200 OK) from local snapshots. Phys.org (source-1) returned 403 to chief:review fetcher — bot-block, not archived. All factual claims (1986, GaAs, -269.15°C, 20 micrometer sample, Siddhartha Dam at Würzburg-Dresden ctd.qmat, Sebastian Diehl at University of Cologne, 2015 theoretical groundwork, molecular beam epitaxy, 2022 Paris 1D, DOI 10.1126/science.aeb4154 vol 392 page 221) confirmed verbatim in ScienceDaily and SciTechDaily snapshots. Direct Dam quotes ('When surfaces grow...', 'We have now succeeded in controlling...') and Diehl quote ('highlights just how fundamental this equation is...') verified verbatim across both ScienceDaily and SciTechDaily snapshots. arXiv abstract quote 'reveal correlation dynamics and scaling exponents in excellent agreement with 2D KPZ predictions' verified verbatim in arXiv snapshot.

All headline, summary, and lead claims fully sourced. Multi-source corroboration for every major specific.

Substantively a clean, well-sourced physics-news article. Single recoverable issue (paraphrase in quote marks attributed to arXiv) is squarely in APPROVE_WITH_CORRECTIONS territory: the substance is fine and a corrections note can honestly inform readers.
