CODEX SHIPS ROLLOUT MIGRATION FRAMEWORK AND CONTEXT WINDOW TRACKING

Codex rolled out a complete migration toolkit for legacy session handling while fixing a critical flaw in how forked subagents track their context windows.

The codex migrate-rollouts command [1] lands with dry-run inspection, explicit apply flags, thread filtering, and throttling controls, plus an optional background migration feature that rescues legacy local sessions at startup without full rescans. This solves the operational pain of moving sessions off the old rollout system while keeping the engine moving. In parallel, context window tracking now identifies subagents by name rather than global state [2], meaning forked agents properly track their own lineage instead of inheriting broken metadata from parents. Codex also began sending model routing hints to the backend [3] via a new x-codex-routing-hint header on HTTP and WebSocket connections, letting the service tier influence request distribution without client-side logic bloat. A fix for subagent MCP startup status settling [4] prevents the TUI from locking into a false "starting up" state when cached servers defer indefinitely. On the infrastructure side, the environment provisioning API consolidation [5] removes separate deferred registration handles in favor of a unified reporting flow. The openai-node SDK also patched its linter to recognize Castiron-generated headers [6] alongside the existing Stainless markers, keeping code generation tooling in sync.
