Monthly summary for 2025-10 focused on the artsy/positron upgrade. Delivered a critical dependency upgrade to OpenSearch and ensured compatibility across development and test configurations, with environment adjustments to align with the newer version. The work reduces risk for production rollouts and sets the stage for future feature work that relies on OpenSearch 2.x capabilities.

2025-08 monthly summary for artsy/positron: Delivered engine-flexible search backend features and completed environment parity improvements. Key work includes a feature-flag to switch between Elasticsearch and OpenSearch, engine-aware client initialization that selects ELASTICSEARCH_URL or OPENSEARCH_URL based on USE_OPENSEARCH, and adjusted delete handling in the distribute model to use the correct document type (_doc for OpenSearch, article for Elasticsearch). Also migrated development and testing environments from Elasticsearch to OpenSearch v1.3.20 with updated configurations and images. These changes reduce migration risk, enable safer experimentation, and improve operational parity across dev/test and production.

April 2025 monthly summary for developer focusing on reliability and test coverage for CDN-related caching in metaphysics.

This work reduces production risk, accelerates future changes, and improves developer confidence.
