Review Comment:
   💡 **Nit:** `r.routeId` may be null for anonymous routes (no `id:` in the 
YAML). `AuthoringTools.routeSources` guards against this (`r.get("routeId") != 
null`), so the output is correct, but this stores `null` in the intermediate 
map and relies on the downstream guard to filter it. Mirror the guard here for 
consistency and to avoid a silent regression if `routeSources` is ever 
refactored:
   
   ```suggestion
                       if (r.routeId != null) {
                           j.put("routeId", r.routeId);
                       }
   ```
