Feb 1, 2026February 2026 monthly summary for global-121/121-platform focusing on delivering type-safe FSP configuration across backend and frontend, with a strong emphasis on reliability and test coverage. Implemented typed properties for FSP configuration (boolean/numeric), expanded type mapping, and ensured proper serialization/parsing in the entity layer. Frontend handling updated to reflect typed properties, with corresponding unit and integration tests refreshed. A key commit (2b5892db1fc3c0f1f43ec8f2f201d02602fe96eb) encapsulated the changes and repository-wide test stabilization followed seed-value adjustments to fix integration-test flakiness. Business value includes reduced runtime risk, more predictable deployments, and a foundation for safer future config changes.
