@github-actions[bot] commented on GitHub (Jan 24, 2026):

This issue appears to be isolated to the /fork command when no valid messages are found. The problem is that selected() in dialog-select.tsx:152 can return undefined when the filtered options list is empty, but the code unconditionally accesses option.value without null-checking.

Related areas to investigate:

  • #10286: Dialog-related keyboard/input issues might share similar root causes with event handling
  • #10209: Selection dialog behavior improvements

This is likely a regression in how empty states are handled in selection dialogs.
