May 2025 monthly summary focused on stabilizing the Helm-based deployment by restoring the Symbols Service StatefulSet, addressing a deployment breakage caused by removing the symbols StatefulSet. The change re-adds the symbols service with its configurations, since modifying the PVC template in a StatefulSet is forbidden and previously caused outages. This work restored expected functionality and stability of the deployment, ensuring symbol-resolution features remain available for downstream workflows and customer-facing tooling.
