May 1, 2026May 2026 monthly summary for groundlight/edge-endpoint. This period delivered substantial reliability and performance improvements across FUSE mount health, load-testing telemetry, modernization of the dependency stack, and benchmarking tooling. The work reduced deployment risk, stabilized edge deployments under rolling updates, and improved visibility into system utilization during tests. Key outcomes include robust mount-s3 health verification to prevent zombie mounts, a standardized resource-monitoring pipeline via /status/resources.json, a migration to uv for dependency management with a compatible Helm deployment, and a configurable resilience posture for slow networks and startup probes. In addition, a lens-shape benchmark was introduced to simplify and consolidate edge-endpoint performance evaluation with the existing benchmarking harness. Overall impact: increased stability and predictable performance of edge-endpoint in production and test environments, with improved developer experience through streamlined tooling and CI improvements.
