CODEX HARDENS MCP RUNTIME STABILITY ACROSS FIVE CRITICAL FIXES

OpenAI shipped a coordinated hardening of the Model Context Protocol layer across Codex, patching race conditions in thread startup, resource access, and authority management that could leave stale configurations in production.

Five commits landed in Codex overnight, all targeting the same underlying problem: MCP configuration changes were racing against thread initialization and runtime refresh cycles [1][3][5]. The most urgent fix centralizes MCP runtime invalidation in ThreadManager so it catches threads mid-startup, preventing stale runtimes from persisting after config reload [3]. Companion fixes address authority staleness in elicitation reviews [4] and ensure managed MCP requirements propagate into active threads [5]. Earlier, a test determinism fix for Apps recovery [1] eliminates a race in the retry flow that was making test results unreliable, and executor skills now properly expose resource-access metadata so explicitly selected skills can read their own resources [2]. On the Node side, the test matrix gate consolidates CI coverage [6], letting the main branch rule replace version-specific checks with one stable context. Python SDK raised its floor to 3.10 [7], dropping Python 3.9 support after upstream EOL and automating monthly version-drift reviews to catch lifecycle changes early.
