  "changelog": "0.10.8: a ceramic capacitor's dielectric is read from the vendor's code in its MPN field (Samsung CL05B is X7R, Murata GRM155R7 is X7R, KEMET, Walsin, TDK and Yageo too), so X7R parts aren't flagged against an assumed 85 °C rating, and the finding says why a rating was assumed (issue 31); Murata C0G parts above 1 nF are seen as C0G in the PDN model.",

  "brief": "Adom Fields: where the current and the heat go on your board.",
  "summary": "Current density on the copper, heat flow through the pours and the vias, and the temperature over the board, solved from the board file itself and shown on the board in 3D. The AI does the analysis and drives the view; the human orbits, zooms, hovers for the number under the cursor, and reads the nets by what they carry and the issues by what to fix. A step in Adom's AI Flow: the walkthrough goes into the video.",
  "description": "Adom Fields reads a KiCad board (its filled polygons, tracks, pads and vias) and a spec (which nets carry what current, which parts dissipate what) and solves three fields on it: the DC current density of every loaded net between its terminals; the heat flow in each copper layer, coupled through the dielectric and every via barrel, from the hot tabs and from the Joule loss of that current; and the temperature rise over the whole board in still and in moving air. Then it serves the board in 3D: the fields painted on each layer, the vias drawn, the hot parts labelled, the nets ordered by what they carry, the issues (a neck where the current squeezes, a tab over its rise budget, a chip missing its thermal vias) with the fix, and the number under the cursor. Everything the UI does a command does, over a live channel, so the AI shows the board off on camera.",
