done: 0128 + 0129 — agents_and_robots HTTP API + agents_dashboard C++ ImGui

Both issues delivered end-to-end:

0128 (backend, merged via dataforge/agents_and_robots/pulls/1):
- HTTP daemon in cmd/launcher with apikey Bearer auth + SSE
- LIVE at https://agents.organic-machine.com via Coolify Traefik + LE cert
- systemd Restart=always
- Unified status autodetect fix applied

0129 (frontend, merged via dataforge/agents_dashboard/pulls/1):
- C++ ImGui app in projects/element_agents/apps/agents_dashboard
- 4 panels: Connection / Agents / Logs / Status
- secret_store_cpp_infra new function (DPAPI Windows / XOR Linux)
- Deployed to Windows Desktop, App Hub tarjeta visible

+# 0130 — Kanban C++ v2
+
+**Status:** pendiente
+
+## Por que
+
+La v1 (`apps/kanban_cpp` borrada el 2026-05-22) mezclaba paneles ajenos al dominio kanban (agent runs, DoD, worktrees, calendar) y un backend que no era reutilizable. Para gestionar los 98 issues activos + 12 flows del proyecto necesitamos una vista board nativa, sin web, con edicion bidireccional de los archivos markdown.
+
+## Que entrega
+
+App kanban_cpp v2 con dos piezas:
+
+1. **Backend Go** (`apps/kanban_cpp/backend/`) — service HTTP en puerto 8487.
+   - Parser bidireccional MD <-> SQLite (cache).
+   - Watcher fsnotify sobre `dev/issues/` (+ `completed/`) y `dev/flows/`.
+   - Endpoints REST: `/api/issues`, `/api/issues/{id}` (GET/PATCH), `/api/flows`, `/api/flows/{id}`, `/api/meta`, `/api/sse`.
+   - PATCH a issue reescribe el frontmatter en disco preservando body + orden de campos.
+
+2. **Frontend C++ ImGui** (`apps/kanban_cpp/`) sobre el framework `fn::run_app`.
+   - Panel **Board**: columnas por status (pendiente / in-progress / bloqueado / completado). Drag-drop = PATCH status.
+   - Panel **Flows**: lista de flows con detalle.
+   - Panel **Filtros** (Aside): multi-select domain, scope, priority, tags.
+   - Panel **Detalle**: edicion de campos frontmatter de un issue (status, priority, scope, tags, depends, blocks).
+   - SSE para refrescar tras cambios externos en disco.
+
+## Sub-issues
+
+- **0130a** — parser MD + scan dirs (funciones registry).
+- **0130b** — backend Go: schema + handlers + watcher + SSE.
+- **0130c** — frontend C++: paneles + http client.
+
+Cada sub-issue mergeable independiente en su rama corta TBD.
+
+## Reusa del registry
+
+Backend Go:
+- `sqlite_open_go_infra`, `sqlite_apply_migrations_go_infra`
+- `http_router_go_infra`, `http_serve_go_infra`, `http_middleware_chain_go_infra`
+- `http_cors_middleware_go_infra`, `http_logger_middleware_go_infra`
+- `http_json_response_go_infra`, `http_error_response_go_infra`, `http_parse_body_go_infra`
+- `random_hex_id_go_core`
+
+Frontend C++:
+- `http_request_cpp_core`
+- `sse_client_cpp_core`
+- `data_table_cpp_viz` (lista flows)
+- `kpi_card_cpp_viz` (contadores por status)
+
+## Crea (delegadas a fn-constructor en 0130a)
+
+- `parse_issue_md_go_infra` — lee .md → struct (frontmatter YAML + body).
+- `write_issue_md_go_infra` — escribe struct → .md preservando body + orden de campos.
+- `scan_issues_dir_go_infra` — walk `dev/issues/` + `dev/issues/completed/`.
+- `scan_flows_dir_go_infra` — walk `dev/flows/`.
+- `watch_dir_fsnotify_go_infra` (si no existe) — events channel.
+
+## DoD
+
+- `fn doctor` verde para ambas apps (artefacts + e2e).
+- `e2e_checks` en ambos `app.md` (build + health + self-test).
+- Drag-drop en frontend reescribe el `.md` correspondiente y `git diff` lo muestra (solo frontmatter, body intacto).
+- Trio obligatorio (`description` + `icon.phosphor` + `icon.accent`) en ambos `app.md`.
+- Sub-repos Gitea creados (`dataforge/kanban_cpp` reactivado o nuevo, mismo nombre).

+## Anti-scope
+
+NO incluye en esta version:
+- Grafo de dependencias (depends/blocks/related visual).
+- Edicion de body MD desde la app (solo frontmatter).
+- Multi-PC sync (backend es local).
+- Crear issues nuevos desde la UI (solo editar existentes).
+- DoD evidence panel, agent runs, calendar, worktrees (la v1 los mezclaba — fuera).
