Provenance Record

Well-structured News piece (Overview / What We Know / What We Don't Know format), 556 words within the 400-1200 News range. Neutral, factual tone throughout with no editorializing or AI self-reference. No sensationalism.

All 5 cited sources personally read and checked against every claim they support. sources-0/1/3/4.html.gz snapshots decompressed and their sha256 hashes verified against manifest.json (all match). source-2 (power-technology.com) snapshot failed with HTTP 403 (bot-blocked); per protocol I fell back to a live WebFetch of https://www.power-technology.com/news/ocean-winds-consent-2gw-caledonia-offshore-project/ and confirmed its content matches the claims and quotes attributed to it (the Mark Baxter and Adam Morrison quotes, the 200-skilled-positions workforce figure, the ScotWind/Aberdeenshire Council references, and the 2030/CfD/FID construction timeline all appear verbatim/consistent in the live page). Findings: (1) gov.scot [source-0.html.gz] — confirms headline, summary, 429km2 area, 140-turbine cap, £1.7bn supply-chain commitment, 2-million-household figure, the John Swinney quote (verbatim), the Caledonia South foundation-mix quote (verbatim), and the seabird compensation plan requirement, all verbatim/consistent. (2) offshorewind.biz [source-1.html.gz] — confirms 2GW/429km2/140-turbine topline, the 40-100m water depth range, onshore consent by Aberdeenshire Council, ScotWind leasing round, and 2030 construction subject to CfD/FID — but does NOT contain the 77-turbine (Caledonia North) / 78-turbine (Caledonia South) / 39-floating-turbine breakdown that the article attributes to it (see Findings below; that breakdown is sourced from gov.scot instead). (3) power-technology.com [WebFetch fallback, snapshot 403] — confirms both direct quotes attributed to it (Baxter 'culmination of years of hard work...', Morrison 'built on Ocean Winds' proud legacy...write the next chapter'), the 200-skilled-positions figure, ScotWind and Aberdeenshire Council references, and 2030/CfD/FID timeline. (4) agcc.co.uk [source-3.html.gz] — confirms both Baxter quotes verbatim, the 200-skilled-positions figure, and the ScotWind/onshore-consent context; note this page is captioned 'by Ocean Winds UK' and 'Member News', i.e. a republished company press release rather than independent reporting. (5) energyglobal.com [source-4.html.gz] — confirms both Baxter quotes and the Morrison quote verbatim; text is near-identical to the AGCC press release, indicating sources 3 and 4 substantially reproduce the same underlying Ocean Winds press release rather than being fully independent reporting (noted as a source-diversity observation, not an accuracy problem — the facts are independently corroborated by gov.scot and offshorewind.biz).

One recoverable misattribution found: the bullet 'Ocean Winds is splitting the capacity evenly between the two sites, with up to 140 turbines total — 77 for Caledonia North and 78 for Caledonia South, including as many as 39 floating turbines — across water depths of 40 to 100 meters, according to Offshore Wind' cites the entire sentence to offshorewind.biz, but the 77/78/39 turbine breakdown does not appear anywhere in the offshorewind.biz snapshot (verified by keyword search — '77', '78', '39', and 'floating turbine' are all absent from the extracted text). That specific breakdown instead comes verbatim from the gov.scot snapshot ('up to 77 offshore Wind Turbine Generators' for Caledonia North; 'up to 78 Wind Turbine Generators (of which no more than 39 shall be floating)' for Caledonia South). Only the 40-100m water-depth figure in that bullet is actually supported by offshorewind.biz. The underlying numbers are all true and independently verifiable in the article's own gov.scot citation elsewhere in the piece — this is a citation/attribution error, not a fabrication — so it is filed as a corrections record rather than grounds for rejection. All other specifics, quotes, and figures in the article trace correctly to their cited sources with no hallucinations detected.

Substantively accurate and well-sourced News piece on a genuinely new topic. One recoverable citation misattribution (turbine-count breakdown attributed to the wrong outlet) does not affect the headline, summary, or lead and is fully correctable with a public corrections note.
