June 2026 monthly summary for openai/codex: Key feature delivered this month is the Turn-scoped Moderation Metadata Forwarding to App-Server Clients via an experimental typed notification. This enables opted-in app-server clients to consume moderation metadata without interpreting raw API events, improving developer ergonomics and client performance. End-to-end flow was implemented to ensure proper processing and transmission through the application server, with clear commit references guiding implementation. Impact: Reduces client-side parsing, lowers latency for moderation workflows, and provides a scalable path for structured moderation data delivery. This work directly supports faster, safer moderation at scale and simplifies downstream client integrations.
