 ### Fixed
 - `herdr config check` now reports unknown config keys with their full paths instead of treating ignored typos as valid configuration. (#1573)
+- Codex panes with customized static terminal titles now fall back to the live working footer instead of remaining idle, while OSC activity remains preferred. (#1563)
 - Named agent prompts now honor live bracketed-paste mode before sending Enter, preserving OpenCode text such as `A != B` instead of triggering shell mode. (#1525)
 - New panes, tabs, layouts, and workspaces using `new_cwd = "follow"` now inherit the foreground process-group leader's working directory instead of an unrelated helper process directory. (#1472)
 - Noninteractive update, plugin, integration, sound, custom-command, and Git subprocesses no longer flash console windows on Windows. (#1468)
