| ID  | Pattern                          | Fix                                    |
| --- | -------------------------------- | -------------------------------------- |
| SF1 | `catch (e) {}`                   | `catch (e) { logger.error(e); throw }` |
| SF1 | `catch (e) { console.log(e) }`   | Show user feedback + log context       |
| SF2 | `.then(fn)` without `.catch()`   | Add `.catch()` or use try/catch        |
| SF2 | `async () => { await fn() }`     | Wrap in try/catch, handle error        |
| SF3 | No error UI states               | Add error boundary, feedback component |
| SF4 | `value ?? defaultValue` silently | Log when using fallback                |
| SF4 | `data?.nested?.value`            | Check and report if unexpected null    |
