+## 2.16.0 — 2026-09-10 — KiCad cad-bridge

+- [New] E2 cad-bridge JSON (`version`, `ref`, `pins`, `sheet`, `uuid`, `severity`). Layout rule ids target pcbnew; others target eeschema.
+- [New] `.kicad_sch` symbols keep `cad_uuid` + `cad_sheet` in `cad_index` (child sheet, not the empty root).
+- [New] Action plugin in `plugins/kicad/` reads the JSON beside `.kicad_pro` / `.kicad_pcb`.
