Provenance Record

Well-structured News piece (688 words, within the 400-1200 News range). Clear Overview/What We Know/Context/What We Don't Know/Analysis sections. Every factual claim is attributed inline to a specific source. The Analysis section appropriately contextualizes the ~50,000 gal/yr output as a demonstration of a commercial process rather than a material dent in aviation fuel demand, without editorializing.

All 3 source snapshots read from disk and integrity-verified (uncompressed sha256 matches manifest for source-0, source-1, source-2). source-0 (PR Newswire, Twelve/AirPlant One release, status 200) confirms: AirPlant One opened June 10 2026 in Moses Lake WA; first commercial-scale US plant producing E-Jet from CO2 + renewable electricity; ASTM D7566 Annex A1; up to 90% lower lifecycle CO2; Alaska Airlines regular domestic flights; Microsoft Climate Innovation Fund investment + book-and-claim SAF offtake; $645M funding round; Flanders and Spies quotes verbatim with correct speakers. source-1 (GlobeNewswire, Vista Projects release, status 200) confirms: first commercial-scale US plant; ~50,000 gal/yr initial capacity; 100% Columbia River hydropower; CO2 from local ethanol producers; ASTM D7566 Annex A1; Mussbacher quote verbatim with correct speaker; Vista Projects as Calgary-based end-to-end engineer. source-2 (PR Newswire, United May 6 2025 release, status 200) confirms: United Airlines Ventures Sustainable Flight Fund investment; 14-year contract, 260 million gallons SAF to a 'large European-based airline company' supporting five airlines; Chang quote verbatim with correct speaker; United's description of Twelve converting CO2 and water into SAF using renewable energy.

Claims align with cited sources. The 'first US commercial-scale power-to-liquid plant' claim is sourced to both the Twelve PR Newswire release and the Vista Projects GlobeNewswire release, not editorialized. The IAG identity behind the 260M-gallon European deal is genuinely ABSENT from source-2 (the release says only 'large European-based airline company' / 'large European airline group'); the article correctly does not name IAG, in keeping with the no-unsourced-specifics rule. Microsoft's role is correctly paraphrased (Climate Innovation Fund + book-and-claim offtake); the article does not present any Microsoft verbatim quote, so the Nakagawa quote present in source-0 is not misused. Proper nouns ('Twelve', 'AirPlant One', 'Moses Lake', 'Alaska Airlines') spelled verbatim against the sources.

High-quality, fully-sourced submission. All direct quotes verbatim with correct speakers, every specific traced to a cited source, the unsourced IAG identity correctly withheld, and Microsoft's role paraphrased rather than fabricated as a quote. No corrections needed. APPROVE.
