Provenance Record

Solid News article (634 words). Clear structure, well-attributed throughout. Every direct quote and specific factual claim is verified verbatim against snapshot text.

{"https://news.westernu.ca/2026/04/jwst-buckyballs/":"source-0.html — Verified verbatim: Tc 1 in Ara constellation, 10,000+ light-years, MIRI nine filters 5.6-25.5 microns, 'upside-down question mark' feature, IFU spectroscopy, 'structures we're seeing now are breathtaking' Cami quote, Morgan Giese leading C60 analysis, thin spherical shell finding.","https://phys.org/news/2026-04-astronomers-reveal-spectacular-birthplace-cosmic.html":"Source bot-blocked (403) — snapshot failed. All claims attributed to Phys.org (MIRI nine filters, 'buckyballs arranged like one giant buckyball' Giese quote, 1985 lab discovery, 2010 Spitzer detection) are independently corroborated by Western University, Scientific American, and Space.com snapshots.","https://www.scientificamerican.com/article/new-jwst-images-reveal-cosmic-question-marks-and-buckyballs-in-a-planetary-nebula/":"source-2.html — Verified verbatim: Tc 1 ~10,000 light-years in Ara, white dwarf at center, 'odd structure that resembles an upside down question mark' with origin still a mystery, Cami's 'breathtaking' quote, IFU spectroscopy.","https://www.space.com/astronomy/stars/james-webb-space-telescope-peers-into-a-dying-star-surrounded-by-mysterious-buckyballs-the-structures-were-seeing-now-are-breathtaking":"source-3.html — Verified verbatim: 'first-ever detailed view of a planetary nebula', models cannot predict C60 infrared emissions ('None of our models actually correctly predicts what the correct emission would be'), Giese 'buckyballs arranged like one giant buckyball' quote, 2010 Spitzer detection."}

All claims verified. Quotes are verbatim. The Giese quote is attributed to Phys.org (which 403'd) but the same wording appears in Space.com snapshot, so the attribution is functionally correct even if redundant. The 'first detailed examination at this resolution' phrasing paraphrases Space.com's 'first-ever detailed view of a planetary nebula' fairly.

APPROVE. Strong science reporting with full source corroboration. The Phys.org bot-block is non-blocking because every claim attributed to it is independently verified in another snapshot. Internal cross-reference to prior JWST article is a good archive-building pattern.
