A deterministic differencing step classifies every discrepancy as confirmed, missing, additional, or inverted. A constrained large language model then turns those deltas into a human-readable report - not to make decisions, but to help engineers understand what changed. The team tested the approach on 26 cases in an industrial firmware context and found strong agreement between machine-generated deltas and expert-curated references.\n\nThe ISO 26262 automotive safety standard demands rigorous traceability between design intent and implemented behavior, and that standard gets harder to satisfy as firmware ages and evolves. What this work offers is an automated first pass - one that reduces the manual archaeology engineers currently do to figure out why a system behaves differently than its documentation says it should.\n\nThe approach is careful to keep the AI component on a short leash: the LLM generates readable summaries, but the structural comparison itself is deterministic. That matters in safety engineering, where an opaque model producing a confident-but-wrong answer could be worse than no automation at all.","[\"firmware\",\"safety\",\"ai\",\"automotive\"]","2026-07-07T04:00:00.000Z","2026-07-07T08:56:19.505Z","2026-07-07T08:56:22.476Z","published",null,[],"ai",[26,27,24,28],"firmware","safety","automotive",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.03135",0,{"sections":35},[36,40,45,50,55,60,65,70,75,79,84,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
