Provenance Record

Clean, well-structured News piece (541 words, within the 400-1200 range). Standard Overview / What We Know / Context / What We Don't Know scaffold, appropriate technical depth, every factual sentence carries an inline citation to a named outlet.

All four source snapshots were fetched at status 200 and read from disk (decompressed .html.gz). source-0.html.gz (Data Center Dynamics) CONFIRMED the load-bearing claims: 1,440 acres at Astra Enterprise Park in De Soto/DeSoto, ~$475M acquired from Sunflower Redevelopment Group in April, former Sunflower Army Ammunition Plant shut down in 1993, Evergy energy service agreement 600MW by early 2028 rising to 2GW at full delivery, Andy Power (president and CEO) 'These transactions support the continued momentum of Digital Realty's three core pillars of growth' quote verbatim, Columbia Capital ~$485M, Teraco +16% for ~$650M lifting stake to 77%, Project Jayhawk codename, Astra North first phase ~280 acres / up to nine buildings / ~3M sq ft / on-site substation, outside-air cooling with evaporative cooling at peaks, announced June 22, 2026. source-1.html.gz (Construction Review Online) CONFIRMED the 2 GW planned capacity, $475M land cost, 600 MW by early 2028, Astra North 280 acres, and 'more than 1,000 workers during peak construction activity.' source-2.html.gz (mlq.ai) CONFIRMED Johnson County location ~30 miles southwest of Kansas City, purchase in cash and common units, and the Astra North 280-acre / nine-building / ~3M sq ft / substation details. Every mlq.ai-attributed claim is corroborated in source-0 or is non-load-bearing geographic/structuring detail — no load-bearing claim rests solely on the mlq.ai aggregator. source-3.html.gz (KSHB 41) CONFIRMED the WWII 'world's largest powder and propellant facility' framing, ongoing Army remediation, 72 of 97 sites cleaned at ~$248M, cleanup mostly complete in 2028 target, and the Panasonic EV battery facility across the street. No snapshot failed; no re-fetch was needed.

All specifics trace to cited sources with no misattribution or hallucination. Acreage (1,440), price (~$475M), 2 GW capacity, 600 MW / early 2028 ramp, De Soto / Sunflower Army Ammunition Plant / 1993 closure, and the Andy Power quote all match the snapshots verbatim. The direct quote is reproduced exactly (source uses a curly apostrophe, article a straight apostrophe — immaterial). The headline '2 GW' and '1,440 acres' are each independently supported (DCD and Construction Review Online).

APPROVE. Integrity checks all pass (Ed25519 signature valid, hash valid, v3 fields present). All four snapshots read from disk and every claim, number, date, place name, and the CEO quote verified verbatim. No fabrication, no misattribution, no orphan source URLs, no duplicate. The only flag is off-allowlist outlets, which is an editorial warning and not correction-worthy, so no corrections record is filed.
