## Why Model-reachable child processes should not inherit Codex launch context. ## What changed - Treat `OPENAI_FEDERATION_RULE_ID` and `OPENAI_IDENTITY_TOKEN_FILE` as non-inheritable environment variables, with case-insensitive matching. - Remove them after shell environment policy overrides and before spawning commands across execution, MCP, hooks, Git helpers, and remote helper processes. ## Testing - Cover inherited and explicitly configured variants, including mixed-case names. - Verify the variables are absent from real child environments and app-server command and process execution.
