May 1, 2025May 2025 performance summary for the common-voice/common-voice repository. Delivered a resilience improvement by implementing comprehensive input validation for API requests to enforce presence of client_id and session.user across endpoints, returning 400 Bad Request when missing instead of allowing crashes. This change reduces outage risk, improves security posture, and streamlines integration with client applications. The work is captured in two commits: 2bdcdf35ed3d90ad4d002e2431cf8791d129e8f4 and 65c806041c6479a9c292bec47d10e684242e11db.
