[Windows] Pet activity badge becomes unclickable after being moved to bottom-right

Reproduce the issue with the Windows Codex Desktop pet overlay and the persisted avatar-mascot-notification-badge-corner value set to bottom-end. Start by tracing synchronization between the native badge rectangle and the transparent overlay's renderer hit testing and mouse passthrough state. Done means the bottom-end badge remains clickable and draggable, and its behavior persists correctly after restart.

What version of the Codex App are you using?

Codex Desktop on Windows, Microsoft Store/AppX package version:

• 26.715.4045.0

What platform is your computer?

• Windows x64
• Microsoft Windows NT 10.0.26200.0

What issue are you seeing?

The pet/avatar activity badge (the small circular control used to show or hide the activity tray) becomes effectively unclickable after it is moved from its default top-right position to the bottom-right of the pet.

The badge remains visible near the pet's right foot, but clicking it no longer shows/hides the activity tray, and dragging it back to another corner does not work. The position persists across a full Codex restart.

The persisted value changes to:

avatar-mascot-notification-badge-corner = bottom-end

Changing only that value back to top-end while Codex is fully closed restores normal behavior after relaunch.

This was observed with a custom v2 pet. The circular badge itself is Codex-owned overlay UI rather than part of the pet image.

What steps can reproduce the bug?

1. Open the Codex Desktop pet overlay and wait for the circular activity/status badge to appear at the default top-right position.
2. Drag or press the badge with enough pointer movement for it to relocate toward the lower-right quadrant of the pet.
3. Release it so the saved corner becomes bottom-end.
4. Try to click the badge to show/hide the activity tray.
5. Try to drag the badge back to the top-right.
6. Fully restart Codex and try again.

What is the expected behavior?

All supported badge corners should have the same click and drag behavior. A badge placed at bottom-end should remain clickable and draggable.

What is the actual behavior?

At bottom-end, the badge remains visible but behaves as if mouse input is passing through it. It cannot reliably be clicked or dragged back, and the unusable position persists after restart.

Workaround

1. Fully quit Codex.
2. In the Codex global state, change only avatar-mascot-notification-badge-corner from bottom-end to top-end.
3. Relaunch Codex.

Additional technical observations

• bottom-end is accepted and persisted as a valid corner; it is not rejected as unsupported.
• The badge uses a very small pointer-movement threshold (approximately 4 px) before a press is treated as a drag. This can explain how the badge is accidentally moved, but not why it becomes unusable afterward.
• The avatar overlay is a transparent/click-through window that switches pointer interactivity based on renderer hit testing.
• The native badge surface appears to be visual-only, so interaction depends on the underlying overlay/DOM hit target.
• The most likely affected area is synchronization between the native badge visual rectangle and the root overlay's hit testing/mouse passthrough state at bottom-end. This is a suspected cause, not a confirmed root cause.

I searched existing open issues before filing. The closest reports I found were #21864 (pet resizing) and #21088 (invisible pet sprite on macOS), but neither describes this bottom-right badge input failure.
