Codex shipped five fixes to prevent stale app state from bleeding into active sessions, while the Node SDK now rejects malformed Zod v3 schemas before they reach the API.

Codex addressed a critical state-management gap where cached app directory data and in-flight requests could outlive their originating account, workspace, or thread [1]. The fix invalidates stale cache, dismisses the app picker, and fetches fresh data on context switches. In parallel, workload identity context now flows through token exchange as an unforgeable session fingerprint [2], preventing sessions with different identity claims from cross-contaminating. Persistent execution threads now use paginated history on resume and fork, keeping transcript ancestry clean without copying source data [3]. Model settings snapshot in StepContext to stay stable across thread updates, ensuring configuration changes apply to the next turn instead of mid-flight [4]. The TUI now surfaces resume and fork status during startup, giving users visibility into session state transitions [5]. On the Node SDK side, the Zod v3 strict schema validator now rejects non-object roots synchronously, using the same path as Zod v4 across all format helpers [6]. Node 22 multipart test flakiness is resolved by buffering uploads only at the intentional mock endpoint [7]. These fixes span 19 commits and 1 release across both desks.

Action items

→ Review workload identity context handling in token exchange integrations openai/codex [plan]
→ Validate Zod v3 schemas against non-object root restrictions before upgrading Node SDK openai/openai-node [plan]
→ Monitor session state behavior in persistent thread workflows after Codex deployment openai/codex [monitor]
