- Each report's concerns were extracted by Nemotron 3 Nano on Nebius Token Factory, each with a quote copied from the report.
- Concerns from reports to National Highways at least six months apart were compared by meaning (Qwen3 embeddings) and wording (TF-IDF).
- The closest pairs were judged by Nemotron 3 Super with reasoning on. Only identical or closely related, with confidence of at least 0.70, are shown.
- Every quote was checked by code as an exact substring of the original text. Names of staff and family are redacted, and the deceased are named by report title only.
