Provenance Record

Excellent, careful materials-science News piece (735 words) that translates a Science paper into accessible terms and clearly separates the structural result from the room-temperature optical finding.

source-0 (Brown University release, 200) confirms verbatim the Tim Moore and Ou Chen quotes (the 'control the amount of FCC and BCC' quote, the 'LEGO blocks' quote, the 'fundamental breakthrough' quote, the 'new phase of matter' quote), the Glotzer lab, the quantum-computing application framing, and the long/sticky-molecule coating. source-2 (ScienceDaily, 200) confirms lead author Yasutaka Nagaoka (senior research scientist), Science volume 392 / issue 6801 / page 951, the DOI 10.1126/science.ady6472, and the NSF/DOE funders. source-1 (Phys.org) returned HTTP 403 to the snapshot fetcher; its four direct quotes (the 'mecon … 14 sides' shape description, the Nishiyama-Wassermann pathway quote, the deep-strong-coupling quote, and the room-temperature quote) plus the Science paper title were verified verbatim against the live URL via WebFetch. source-3 (Science paper) is paywalled (403) and cited only for the DOI reference.

Every quote is verbatim and correctly attributed. No headline/summary/lead claim is sole-sourced to a bot-blocked page: the deep-strong-coupling, room-temperature, mecon/14-sides/truncated-octahedra, and FCC/BCC facts all appear in the accessible Brown and ScienceDaily snapshots, and the Science paper's DOI/volume/issue/page are independently in ScienceDaily.

High-quality, fully-verified science submission; the two 403 sources were resolved by live verification and corroboration. APPROVE.
