A worker has collapsed beside an active chemical leak.
A worker has collapsed beside an active chemical leak.
Synthetic case. References were set by ClefBench and have not received an independent second review. These are recorded results, not a new model call.
urgent
Does this situation meet level 2 or 3 on the severity rubric and therefore require escalation?
Reference: true
| Model | Run 1 | Run 2 | Run 3 | Changed answer? |
|---|---|---|---|---|
| Clef | true | true | true | No |
| Clef-flash | true | true | true | No |
| Jev 1.13 | true | true | true | No |
Yes/no uses a 50% threshold. Score values are weighted scale indices; error flags and stability use the nearest level. Use the rule and full distribution to judge whether a difference matters for your task.
category
Select the main risk domain.
Reference: safety
- security: Digital access, data or cybersecurity
- safety: Physical harm, fire, building or chemical safety
- operations: Availability, logistics or business workflow

severity
Rate the risk using only stated evidence.
Reference: 3
- 0: No unresolved risk or impact
- 1: Contained minor issue, blocked attempt, or safe workaround
- 2: Serious unresolved vulnerability, potential physical harm, or a regional workflow blocked
- 3: Active data theft or destruction, immediate threat to life, or global outage with no workaround
| Model | Run 1 | Run 2 | Run 3 | Changed answer? |
|---|---|---|---|---|
| Clef | 2.8972 | 2.8972 | 2.8972 | No |
