+## 🏁 [R49.seccion-final.L1] Fix R49 dashboard gráficos visibles deployed
+
+### Diagnóstico empírico
+
+| Problema | Root cause R49 |
+|----------|---------------|
+| Counts = -1 todos stores | psycopg2/qdrant-client/neo4j-driver NO instalados en container `ember-marimo-render` (solo marimo+pandas+plotly) |
+| pip install runtime impossible | Container read-only filesystem ❌ |
+| PEP 723 marker no funcional | `marimo run` NO ejecuta auto-install dependencies |
+| Gráficos no aparecen | Cells fallaban silently con `mo.md("plotly no instalado")` por imports en error |
+
+### Fix aplicado v2
+
+| Cambio | Detalle |
+|--------|---------|
+| **Imports** | `urllib.request` built-in (sin deps externas) + `plotly.graph_objects` ya disponible |
+| **Qdrant LIVE** | REST API + api-key header `ca02f899...` env QDRANT__SERVICE__API_KEY |
+| **Hostnames** | Docker network: `qdrant` → 172.18.0.10, `postgres-mnemo` → 172.19.0.7, `neo4j-mnemo` → 172.19.0.6 |
+| **PostgreSQL/Neo4j** | Snapshot hardcoded R48 (sin REST API expuesta) |
+| **Gráficos** | 5 plotly funcionales: bar+line throughput · stacked decomposition · scatter sesiones × Φ · bar skill_dominante · bar night periods |
+| **Tamaño notebook** | 14KB (vs 28KB v1) — más conciso |
+
+### Refresh URL
+
+**`https://render.brasaluz.com/?file=VP-26-SP_DASHBOARD_MEMORIA_MASTER.py`**
+
+Hard refresh **Ctrl+Shift+R** post-Authelia → deberías ver:
+- ✅ Counts Qdrant LIVE (ember_experience=1746 fresh)
+- ✅ Counts PostgreSQL+Neo4j snapshot R48
+- ✅ 5 gráficos plotly renderizados
+- ✅ Selector perspective funciona (ALL filtra correctamente)
+- ✅ Error Console transversal con 5 bugs activos
