 ### Providers
 
+- Codex no longer requests the MCP catalogue that can exceed its chat transport limit on new or resumed threads. Oversized stdout failures during launch stop automatic retries and preserve Retry/Dismiss recovery. MCP status now reflects startup notifications, so servers without notifications may be absent. (#316)
 - The Codex skill picker includes skills installed through plugins, including Superpowers. (#298)
 - Codex stderr logs no longer appear as raw **Codex warning** rows with ANSI escapes and incorrect severity. (#299)
 - The Claude model picker shows model names rather than taglines with Claude Code 2.1.318. (#300)

 ### Regression coverage
 
+- The Unix PTY setup-failure test waits for a complete descendant PID before checking process-group cleanup. The native macOS arm64 CI build has a four-hour job budget, matching x64. (#314)
 - Changed files coverage now clicks **View diff** through the chat and verifies that the selected diff stays open through same-turn plan updates. (#275)
 - The packaged resume-at-end check follows the active timeline through turn completion, avoiding stale scrollers and replies from history. (#215)
