Mar 1, 2025March 2025 monthly summary — delivered observability improvements for OCR2 configuration writes and increased deployment flexibility by enabling transmitter operation without a Mercury server. Key work included standardized, infow-based logging for OCR2 write-config operations (including spec_id and plugin_id), updates to LLO config validation to allow CRE transmitters to run without Mercury Server, and a null-pointer fix in Mercury CapabilitiesRegistry when no Mercury servers are present. Tests were updated to cover no-server scenarios and ensure logging changes are correctly emitted. Business value: faster issue diagnosis, safer operations in no-server environments, and expanded deployment options for CRE/Mercury integrations. Technologies involved: Go, structured logging (infow), OCR2, CRE, Mercury server integration, and test-driven changes.
