## Workarounds

1. **** (85% success)
   ```
   Check permissions before access: if fi, err := os.Stat(path); err == nil && fi.Mode().Perm()&0444 == 0 { return errors.New("no read permission") }
   ```
2. **** (90% success)
   ```
   Use os.Open with proper error handling: f, err := os.Open(path); if err != nil { if os.IsPermission(err) { handle } }
   ```

## Dead Ends

- **** — Security risk; not always possible. (70% fail)
- **** — File not read; logic breaks. (90% fail)
