# Exit codes
| `0` | Success — no HIGH-severity conflicts |
| `1` | One or more HIGH-severity conflicts found (`aiscope check` only) |
| `2` | Argument or I/O error |
## Behavior by command
| `aiscope` | ❌ no — informational only |
| `aiscope scan` | ❌ no — same as above |
| `aiscope check` | ✅ yes — exits `1` |
| `aiscope watch` | ❌ no — runs forever |
## Why `scan` doesn't fail
`scan` is for inspection (TUI, JSON, card). Failing it would break dashboards
and watch loops. Use `check` whenever you want a hard gate.
## CI snippet
```yaml
- run: aiscope check --specific .
# exit 1 fails the job; no extra config needed
```
