+entries, err := VaultManifestRead("/home/lucas/fn_registry")
+if err != nil {
+    log.Fatal(err)
+}
+for _, e := range entries {
+    fmt.Printf("%s/%s -> %s\n", e.ProjectID, e.Name, e.Path)
+}
+// app_turismo/turismo_spain -> /home/lucas/vaults/turismo_spain
+// app_finance/finance_data  -> /home/lucas/vaults/finance_data
+```
+
+## Notas
+
+`VaultManifestEntry` es un tipo local de esta funcion (no un tipo del registry). Contiene:
+- `ProjectID` — basename del directorio `projects/<proj>/`, inferido del path del manifest.
+- `Name`, `Description`, `Path`, `Tags` — copiados del yaml tal cual.
+- `ManifestFile` — path absoluto al vault.yaml de origen, util para mensajes de error y trazabilidad.
+
+El parseo usa `gopkg.in/yaml.v3` (ya en go.mod). Si un manifest falla, la funcion devuelve
+error inmediatamente con el path del fichero problemático. Los manifests sin entradas
+`vaults:` contribuyen cero entries (no es error). Si no existe ningun `projects/*/vaults/vault.yaml`
+el resultado es slice vacio sin error.
