 - TUI: make searchable-select filtering and highlight rendering ANSI-aware so queries ignore hidden escape codes and no longer corrupt ANSI styling sequences during match highlighting. (#4519) Thanks @bee4come.
 - Agents: return an explicit timeout error reply when an embedded run times out before producing any payloads, preventing silent dropped turns during slow cache-refresh transitions. (#16659) Thanks @liaosvcaf and @vignesh07.
+- Agents/OpenAI: force `store=true` for direct OpenAI Responses/Codex runs to preserve multi-turn server-side conversation state, while leaving proxy/non-OpenAI endpoints unchanged. (#16803) Thanks @mark9232 and @vignesh07.
