Provenance Record

Clear, well-structured News piece (669 words, within the 400-1200 News range). Sections (Overview, What We Know, The Pivot From Blue Origin, Constellation Buildout, What We Don't Know) cleanly separate the launch facts, the technical specs, the launch-provider switch, and explicit unknowns. Framing correctly centers the new June 17, 2026 Falcon 9 launch, with the BlueBird 7 loss positioned as context for the launcher pivot rather than the lead.

Read 4 of 5 committed snapshots from disk and verified each cited claim. source-0 (Spaceflight Now): confirmed liftoff 2:39 a.m. EDT (0639 UTC) from SLC-40, deployment confirmation update at 4:10 a.m. EDT, booster B1077, '156th landing on this vessel and the 625th booster recovery for SpaceX to date', 'A Shortfall of Gravitas' in the Atlantic, ~2,400 sq ft (223 sq m) array, and the BlueBird 7 'altitude was too low to sustain operations with its on-board thruster technology' / de-orbit quote — all verbatim. source-1 (SatNews): confirmed 'upper-stage engine thrust deficiency', 'failing to reach its intended trajectory and eventually burning up upon reentry', 'mid-June 2026', 'Supplemental Coverage from Space (SCS)', '$1.2 billion in contracted revenue', '45 to 60 operational satellites by the end of 2026' — all verbatim. source-2 (Space.com): confirmed 8.5 minutes to landing, Atlantic Ocean, 'A Shortfall of Gravitas', '29th launch and landing for this particular booster' — all verbatim. source-3 (ast-science.com): confirmed 'nearly 2,400 square feet arrays, which will make them the largest commercial phased arrays ever deployed in low Earth orbit', '120 Mbps per coverage cell', '2000+ active cells per satellite', '10 GHz of processing bandwidth' — all verbatim. source-4 (Investing.com) snapshot FAILED with HTTP 403 (bot-blocked); as a last-resort fallback I WebFetched the live URL and confirmed the Avellan quote, the 'nearly double the peak data speeds of Block 1 ... 98.9 Mbps' stat, and the 'BlueBirds 11, 12, 13 in final preparation ... through BlueBird 37 in production and assembly' claims. Note: satnews.com and ast-science.com are not in config/source_allowlist.txt but both returned clean HTTP 200 snapshots and are credible (industry trade outlet; official company spec page); investing.com IS in the allowlist but was the bot-blocked source.

All specifics (dates, times, booster tail number, landing/recovery counts, array dimensions, throughput figures, financial and constellation targets) trace to and match their cited sources. The two booster-count framings are correctly split into separate single-source sentences (Space.com: '29th launch and landing'; Spaceflight Now: '156th landing / 625th recovery') with no compound misattribution. The internal cross-reference to the April BlueBird 7 loss resolves to a real published article (2026-04/21-blue-origins-new-glenn-nails-first-booster-reuse-but-loses-bluebird-7-satellite-to-wrong-orbit) and its characterization ('first booster reuse but placed BlueBird 7 in the wrong orbit') matches that article's summary.

Substantively accurate, well-sourced, and original. Every cited claim was verified against a snapshot or a live fallback fetch. APPROVE_WITH_CORRECTIONS: publish with a single clarification noting the Avellan quote's indirect-speech framing in the source. The two source-archivability warnings (allowlist, 403) are not content errors and do not affect the verdict's substance.
