August 2025 (2025-08) — Enhanced observability for internxt/drive-server-wip by adding a fixed identifier to request logs and removing a noisy, non-functional debug log in the throttler guard. These changes improve log filtering and reduce noise, enabling faster root-cause analysis during incident response. The work was limited to middleware and guard components, with commits focused on instrumentation and code cleanliness, and no changes to external behavior.
