The tool generates synthetic data streams with exact labels and then probes frozen model representations using a standardized linear-probe protocol. The team evaluated 37 model-and-adapter combinations. The headline finding is an uncomfortable gap: the best dense-probe result across all systems hit a mean masked R² of 0.689, while a dense-feature oracle scored 0.999.\n\nThat gap matters because it exposes a specific failure mode the field has largely ignored. A model can score well on forecasting or classification benchmarks while still hiding the fine-grained state information — timing, phase, amplitude — that a practitioner needs when something goes wrong. Coarse-grained accessibility looks fine; granular accessibility does not.\n\nThis is the diagnostic equivalent of a car passing an emissions test but failing a brake inspection. The time-series model community has leaned heavily on downstream task scores as a proxy for representation quality, and Aionoscope is a direct challenge to that assumption. It joins a small but growing set of interpretability tools pushing back against the idea that benchmark performance is the same as genuine transparency.","[\"ai\",\"machine-learning\",\"time-series\",\"interpretability\"]","2026-07-02T04:00:00.000Z","2026-07-02T06:31:35.968Z","2026-07-02T06:31:38.861Z","published",null,[],"ai",[24,26,27,28],"machine-learning","time-series","interpretability",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.00956",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"]
