CODEX HARDENS APP-SERVER INTEGRATION AND TIGHTENS ADMIN CONTROLS

By RepoJournal · Filed 06:03 UTC on May 12, 2026 · About OpenAI

Codex shipped deterministic integration tests that prove the SDK, app-server runtime, and public clients work together end-to-end, plus three security and capability wins for managed deployments.

The SDK integration harness [1] closes a critical testing gap — behavioral tests could catch wrapper mistakes, but they never validated that the pinned app-server process, request routing, and sync/async clients actually worked together in production. This PR starts the real app-server and mocks only at the HTTP boundary, giving you the confidence that SDK changes won't break at runtime. On the capability side, auth elicitation now advertises itself properly [2] when enabled behind the feature flag, ensuring backward compatibility and giving servers explicit signal before they send elicitations. Admins got the tool approval win they needed: managed requirements can now enforce per-tool approval rules centrally [3], closing the gap where only normal config could express those constraints. Security-critical: managed filesystem deny-read restrictions now survive escalation paths [4] — explicit escalations, prefix-rule allows, and sandbox-denial retries can no longer rebuild the runtime policy and expose paths an administrator locked down. On the client side, remote iOS and Android clients no longer bloat `thread/resume` responses with MCP tool call payloads and image-generation results [5]; this is a temporary redaction layer while the team builds toward paginated SQLite-backed APIs.
