Updates and recovery
What to do when a Codex theme stops working after an update
A fail-closed recovery checklist for Codex theme compatibility, changed client builds and returning to native appearance.
Updated
Recover first
A client update can change structural surfaces or selectors even when the UI looks similar. Recovery should be a normal workflow, not an emergency afterthought.
- Pause the advanced adapter
- Restore native appearance settings
- Confirm the application launches and core controls are visible
- Save the build number and observed failure without recording private content
Verify the exact build
Compatibility should be explicit by platform, app build and capability level. A new build begins as pending and becomes verified only after representative surfaces and recovery have been tested.
Reapply with a rollback path
Before reapplying, inspect known limitations, keep a native fallback and test settings, prompts, code, terminal and diff surfaces. If any required node is missing, fail closed.
Frequently asked questions
Why should an unknown Codex version be blocked?
Because a visually small client change can move or remove a structural target. Blocking prevents a stale adapter from hiding controls or leaving the interface unusable.
Can a visual theme restore removed Codex data or features?
No. It can restore appearance settings only. Product data and removed features remain outside the theme layer.
