[macOS 26.707.31123] Right Command global dictation no longer works after Codex → ChatGPT integration

Summary

After updating from the standalone Codex app to the integrated ChatGPT desktop app, global dictation bound to Right Command no longer completes dictation into arbitrary text fields on macOS. It worked before the integration update.

This may be a recurrence of the global-dictation regression reported in #27296.

Environment

• macOS: 26.5.1
• ChatGPT: 26.707.31123 (build 5042)
• Bundle ID: com.openai.codex
• Shortcut: globalDictationHold → RightCommand

Steps to reproduce

1. Configure Global Dictation (Hold) for Right Command.
2. Focus a text field in another macOS app.
3. Hold Right Command, speak, and release it.

Expected behavior

The global dictation UI starts and the transcript is inserted into the focused text field.

Actual behavior

Global dictation no longer produces or inserts text in arbitrary text fields after the integration update.

Diagnostics

• The RightCommand binding is still present in the app's keybindings configuration.
• bare-modifier-monitor --key RightCommand is running and reports ready.
• Microphone, Listen Event / Input Monitoring, and Accessibility authorization are allowed.
• Secure Input is off and no HID key remapping is configured.
• The global-dictation lock belongs to the currently running app; there is no stale lock.
• App logs contain no microphone-, accessibility-, or hotkey-permission denial.
• The last successful global-dictation history timestamp is July 6, before the July 9/10 integration update. No transcript content is included here.

Related issues

• #27296 — nearly identical global-dictation regression after an earlier update.
• #31909 — another global-shortcut regression reported on the same 26.707.31123 build; possibly related, but not necessarily the same cause.
