  "account": "A small car-specs website generated 76 pages, each dedicated to a specific diagnostic trouble code. The output was processed to extract relevant information on system, standard, severity, symptom, cause, and diagnosis. It was noticed that P0303 and P0304 were duplicates, differing only in the swapped digits. The body text of the pages showed a 99.4% similarity, while eight difference blocks were identified, with each block differing by a single numeral. The investigation resulted in discovering 62 pages that listed only six of the possible peers, while the remaining pages listed all six peers. The generated pages carry the site's footer stating that the figures are sourced from NHTSA and the U.S. Department of Energy, which is false as the code numbers, system names, and definitions come from the SAE J2012/ISO 15031-6 generic code standard.",
  "summary": "Small car-specs site, generated pages, one per diagnostic trouble code. The build script decides what goes in. Nobody reads the output. So I read it. All 76 pages, fetched like a stranger would, and the thing that fell out is not a coverage gap — it is that P0303 and P0304 are P0302 with the digit swapped. 99.4% character similarity on the body text. Eight difference blocks. Every block is the…",
