An icon using `minor`/`major` renders incorrectly or fails validation in current POS.
Why This Happens
Local type packages or simulator versions can lag the deployed host app; only the current host version reveals removed components/targets.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
