# DeviceBench
**A fail-closed safety broker for AI agents that actuate ventilators, infusion pumps, and monitors.**
DeviceBench is the benchmark corpus for *Fail Closed at the Bedside: A Device-Safety Broker for Agents that Actuate Life-Critical Medical Devices*, the `qubroker` module of the QUOKKAGUARD program. It ships with the [`qubroker`](https://github.com/quome-cloud/qubroker) repository, which contains the `qfire` gateway layer under test, the experiment harness, and the paper.
A version-pinned device invariant table (devicebench/devices.json, 014-devices-v1, embedded into the binary via include_str!) plus five deterministic JSONL corpora over ventilator, infusion pump, and cardiac monitor: 216 live-agent scenarios (V1 out-of-range actuation, V2 alarm/safety-function interference, V3 classification-integrity violation, 54 each, plus 54 matched safe cases), 120 legitimate titrations, 60 partition cases with a no-agent control, 60 degradation KPI traces with injected onset, and 40 chaos fault sequences; seed 42, no real device data.
**All data are synthetic.** No real patient data or protected health information (PHI) is included; clinical content is generated from templates with fixed seeds.

| File | Size | Rows |
|---|---|---|
| `devicebench/degradation.jsonl` | 23 KB | 60 rows |
| `devicebench/devices.json` | 2 KB | |

### Record schemas
- `devicebench/degradation.jsonl`: `case_id`, `device`, `onset`, `kpi_trace`
- `devicebench/faults.jsonl`: `case_id`, `device`, `sequence`
- `devicebench/legit.jsonl`: `case_id`, `device`, `risk_class`, `param`, `value`, `patient_kg`
- `devicebench/partition.jsonl`: `case_id`, `device`, `last_cmd`, `no_agent_harm`
- `devicebench/scenarios.jsonl`: `case_id`, `device`, `vuln`, `prompt`, `proposed_param`, `pressured_value`, `safe_value`, `patient_kg`, `ground_truth_unsafe`
## How it was generated
The corpus is produced by the generator in the paper repository and is fully deterministic (fixed seeds), so it can be regenerated byte-for-byte.
```bash
# from the qubroker repository root (deterministic seeds)
python3 scripts/014-device-broker/gen_devicebench.py
```
## Intended use
Evaluating the **device** enforcement layer of a clinical-agent security gateway (HAARF control C8.3/8.6/3.1): When an AI agent actuates a ventilator, infusion pump, or cardiac monitor, a wrong action is immediate physical harm, and a compliant model under clinical pressure will set whatever value it is told to.
The experiments that consume it (E-series in the paper) are reproduced from the repository:
```bash
git clone https://github.com/quome-cloud/qubroker
cd qubroker
cargo build --release
```
then follow the *Reproduce the experiments* section of its README.
