Aug 1, 2025August 2025 highlights for compdemocracy/polis focused on data hygiene, reliability, and scalability improvements that directly enhance user privacy, system stability, and performance. Delivered a Conversation Data Reset and Cleanup Tool to purge existing conversation data across DynamoDB and S3/MinIO, with optional narrative cleanup by report ID. Refactored email delivery to exclusively use AWS SES with explicit error handling and a robust fallback across multiple transport types to improve deliverability and fault tolerance. Strengthened CI/test infrastructure with Docker Compose and Cypress enhancements, including Nginx proxy configuration, SSL cert mounting, and a new client-participation-alpha service, accelerating feedback cycles. Increased compute capacity for the Math Worker by enlarging the block device to 20 GiB (GP3 EBS) to support heavier workloads. Fixed TopicAgenda authentication/token handling with centralized token logic to ensure correct tokens from local storage, boosting security and API reliability. Added Bulk Comment Upload CSV guidance to improve client-admin usability. Overall, these changes deliver tangible business value through safer data lifecycles, more reliable communications, faster testing feedback, and better scalability.
