December 2025 — Focused on stabilizing deployments for CMSgov/dpc-app by improving deployment health checks and alerting. Replaced an infinite loop with a bounded loop that monitors ECS rollout state and validates target health via AWS commands, and added a timeout mechanism to alert on failed deployments earlier. These changes reduce false positives, shorten deployment MTTR, and increase production readiness. Related changes consolidate health-check logic in the deployment script (commit 28c774b57a63333e12989e308b6cf1c009c9a554).

In November 2025, focus centered on stabilizing the test infrastructure for CMSgov/dpc-app and reducing production risk by tightening dependency management. Key actions included scoping test dependencies to the test lifecycle, migrating test utilities into a shared commons module to prevent leakage into production, and updating dependency scopes to 'provided' to avoid transitive runtime dependencies. These improvements enhance test reliability, architectural cleanliness, and maintainability, enabling faster, safer iterations and deployment confidence.
