What issue are you seeing?

When Codex returns a local file link in chat, clicking the link does not open the real file in VS Code.

Instead, VS Code opens a blank editor tab / blank file buffer.

I verified that the file exists on disk and has content. The issue seems to be in how the Codex App renders or resolves local file links.

Reproduction context:

• OS: macOS
• Editor: VS Code
• Workspace path contains spaces
• Workspace is inside a cloud-synced directory (Google Drive)
• Example real file path:

/Users/.../My Drive/dev/AIOS/2026-03-06-assistente-onboarding-telas.md

What I tested:

1. Standard markdown link to the absolute path
2. Markdown link with destination wrapped in <>
3. Absolute path with #L1

None of them opened the correct file from the Codex chat UI.

Observed behavior:

• The file link in chat is not resolved correctly
• In all cases the path appears to be rewritten with %20
• Clicking opens a blank file in VS Code instead of the existing file on disk

What steps can reproduce the bug?

Reproduction context:

• OS: macOS
• Editor: VS Code
• Workspace path contains spaces
• Workspace is inside a cloud-synced directory (Google Drive)
• Example real file path:

/Users/.../My Drive/dev/AIOS/2026-03-06-assistente-onboarding-telas.md

What is the expected behavior?

Expected behavior:

• Clicking a local file reference in Codex chat should open the existing file in VS Code at the correct path
• Paths with spaces should be handled correctly
• The app should not create/open an empty buffer when the target file already exists

Additional information

Important note:

• This does not appear to be a project issue or a VS Code issue
• The file definitely exists and is readable
• Opening the same path manually in VS Code works
