When an agent needs to make a change, the graph tells it exactly which surrounding context is relevant, so the model retrieves only that slice instead of re-processing the entire file. Tested on 1,900 benchmark cases across six state-of-the-art models, the system pushed consistency scores from 56% to 76% while also reducing token consumption.\n\nThe token angle is where this gets interesting beyond accuracy gains. The paper finds that LEDGER running at low reasoning effort matches the baseline at high reasoning effort — meaning an explicit dependency map can do work that would otherwise require the model to reason its way through. That is a meaningful trade-off: structured retrieval is cheap and deterministic, while heavy reasoning is expensive and prone to drift in long documents.\n\nMost current approaches to agentic document editing either feed the whole document into context — expensive and slow — or rely on naive chunking that loses cross-document relationships. LEDGER sits between those extremes. Whether it survives contact with real-world document chaos — legal contracts full of defined terms, codebases with circular imports, sprawling wikis with stale links — is a different question the benchmark does not fully answer.","[\"ai\",\"document-editing\",\"retrieval\",\"agents\"]","2026-06-30T04:00:00.000Z","2026-06-30T08:06:08.125Z","2026-06-30T08:06:11.039Z","published",null,[],"ai",[24,26,27,28],"document-editing","retrieval","agents",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.28379",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"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":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
