+# kanban_cpp
+
+Kanban C++ v2 para gestionar `dev/issues/` y `dev/flows/` del registry. Frontend ImGui sobre `fn::run_app`, backend Go local en `backend/` que parsea los `.md` a SQLite y expone REST + SSE.
+
+## Build
+
+```bash
+# Backend
+cd apps/kanban_cpp/backend && CGO_ENABLED=1 go build -o kanban_cpp_backend .
+
+# Frontend
+cmake --build cpp/build/linux --target kanban_cpp -j
+```
+
+## Run
+
+```bash
+# Terminal 1: backend
+apps/kanban_cpp/backend/kanban_cpp_backend --port 8487 --registry $PWD
+
+# Terminal 2: frontend
+./cpp/build/linux/apps/kanban_cpp/kanban_cpp
+```
+
+Por defecto el frontend apunta a `http://127.0.0.1:8487`. Cambiar con `--backend http://host:port`.
+
+## Self-test
+
+`./kanban_cpp --self-test` — smoke headless (state singleton, filtros, HTTP wrapper sin backend).
+
+## Paneles
+
+1. **Board** — 4 columnas (pendiente / in-progress / bloqueado / completado). Drag-drop entre columnas reescribe el `.md` correspondiente via PATCH al backend.
+2. **Flows** — tabla de flows. Click para detalle.
+3. **Filters** — sidebar multi-select de priority / scope / domain / tag + include_completed.
+4. **Detail** — combos para status/priority/scope + CSV editors para tags/domain/depends/blocks. Body MD read-only.
+
+## Anti-scope (issue 0130)
+
+- Sin grafo de dependencias.
+- Sin edicion del body MD (solo frontmatter).
+- Sin crear issues nuevos.
+- Sin DoD panel / agent runs / worktrees.
