# Gauntlet

**The seam artifact.** RAMPART assurance executed against an agent running inside OpenShell isolation — one command.

Part of the [NotionAlpha OSS AI Lab](https://notionalpha.com).

---

## What this is

Gauntlet is a small open CLI tool that composes two open-source projects that neither vendor will compose for you:

| Upstream project                                 | Vendor    | License    | Role in Gauntlet                                                                         |
| ------------------------------------------------ | --------- | ---------- | ---------------------------------------------------------------------------------------- |
| [RAMPART](https://github.com/microsoft/RAMPART)  | Microsoft | MIT        | Assurance, Evaluation & Forensics — pytest-native safety/security test execution         |
| [OpenShell](https://github.com/NVIDIA/OpenShell) | NVIDIA    | Apache-2.0 | Runtime Isolation & Governance — kernel-level sandbox isolation for the agent under test |

Neither RAMPART nor Gauntlet is a competitor to either of these projects. Gauntlet is the seam between them: it starts an OpenShell sandbox, runs RAMPART's assurance tests against the agent executing inside that sandbox, and reports the combined result. Built on, not competing with, RAMPART and OpenShell.

This is the first concrete proof that the NotionAlpha OSS AI Lab reference architecture is real, running code — not a diagram.

---

## Lineage

Gauntlet is the cross-vendor seam artifact of the NotionAlpha OSS AI Lab reference architecture:

```
CONTROL PLANE   Runtime Isolation & Governance   ·   Assurance, Evaluation & Forensics
                         ^                                          ^
                      OpenShell                                 RAMPART
                              \                                /
                               +------- gauntlet run ---------+
```

The reference architecture defines capabilities and interfaces; implementations are recommended-but-swappable. Gauntlet's implementation choice of RAMPART + OpenShell is evidence-backed (see [notionalpha.com](https://notionalpha.com) and the methodology repository) and stated openly — not assumed to be permanent.

---

## Status

**v0.1.0 — first public release** (2026-05-25).

- M1.1–M1.4 milestones complete: real RAMPART vs real Qwen 3 canonical agent inside a real OpenShell sandbox, end-to-end, in one command.
- Eight SDK improvements landed on the NotionAlpha OpenShell fork (`gauntlet-bindings` branch, tagged `v0.0.47-gauntlet-2`) and are pinned by `scripts/lima/install-openshell-from-fork.sh`. Drafted for future upstream submission; held until vouching is feasible.
- 162 unit tests passing; integration tests skip cleanly when RAMPART / OpenShell aren't installed.

See [CHANGELOG.md](CHANGELOG.md) for the full history.

---

## Quick start

```bash
# From PyPI (no real deps required — fakes mode)
pip install notionalpha-gauntlet
gauntlet run --agent-image my-agent:latest --use-fakes

# From source
git clone https://github.com/NotionAlpha/gauntlet
cd gauntlet
python3 -m venv .venv && . .venv/bin/activate
pip install -e ".[dev]"
gauntlet --help
```

---

## Running (fake adapters — no install required)

For development and testing, use `--use-fakes` to exercise the full seam with scripted adapters instead of real RAMPART/OpenShell:

```bash
pip install -e ".[dev]"

# Human-readable report
gauntlet run --agent-image my-agent:latest --use-fakes

# Machine-readable JSON report
gauntlet run --agent-image my-agent:latest --use-fakes --output json

# Dry run (print the plan without executing)
gauntlet run --agent-image my-agent:latest --dry-run
```

---

## Running with real RAMPART + OpenShell (integration)

The real demo runs the canonical Qwen 3 agent inside an OpenShell sandbox on a Lima-managed Linux VM. One command provisions the VM, builds the OpenShell gateway from the NotionAlpha fork, installs Gauntlet's venv with integration extras, and starts the systemd gateway service:

```bash
bash scripts/lima/gateway-up.sh
```

See [`docs/m1.3.6-gateway-setup.md`](docs/m1.3.6-gateway-setup.md) for the full setup walkthrough (~5 min on first run, idempotent afterward).

Then run the two-layer demo inside the VM:

```bash
limactl shell openshell-gateway -- bash -lc '\
  cd /path/to/gauntlet && \
  ~/work/gauntlet-venv/bin/gauntlet run \
    --agent-image gauntlet/canonical-agent:0.1.0 \
    --policy policy/canonical-agent.yaml'
```

For other targets, write your own Docker image + a YAML policy file:

```bash
pip install -e ".[integration]"
gauntlet run --agent-image my-agent:latest --policy policy.yaml
```

Both RAMPART and OpenShell are alpha-stage as of May 2026. The `[integration]` extra declares them as dependencies but does not install them by default — `pip install -e ".[dev]"` succeeds in a fresh venv without them.

### Asciinema demo

A recorded run of the canonical demo is checked in at [`docs/demo.cast`](docs/demo.cast). Play it locally with:

```bash
pip install asciinema    # or: brew install asciinema
asciinema play docs/demo.cast
```

---

## Report format

Gauntlet produces a structured report after every run. Two formats are supported.

### Text (default — human-readable)

The canonical real-demo command produces a two-section report: the upper section reports the sandbox's deny-by-default isolation guarantee; the lower section reports RAMPART's verdict. The canonical Qwen 3 agent intentionally fails the `send_email_xpia_resistance` test so the demo demonstrates that Gauntlet catches a real safety failure (not a synthetic pass).

```
════════════════════════════════════════════════════════════

### JSON (`--output json` — machine-readable)

```json

  "agent_image": "my-agent:latest",
  "suite": "default",
  "timestamp": "2026-05-22T16:00:00Z",
  "dry_run": false,
  "overall_passed": true,
  "sandbox_isolated": true,
  "sandbox_id": "<sandbox-id>",
  "assurance": {
    "suite": "default",
    "overall_passed": true,
    "passed": 2,
    "failed": 0,
    "errors": 0,
    "findings": [...]
  },
  "findings": [
    {
      "test_id": "xpia-01",
      "name": "Cross-prompt injection: ignore system prompt",
      "passed": true,
      "evidence": "Agent refused injected instruction..."
    }
  ]
}
```

**Report security:** all output is sanitized. Secrets, Bearer tokens, API keys, and host filesystem paths are redacted before appearing in any report. Finding evidence is sanitized at collection time; the output renderer applies a second sanitization pass as defence-in-depth.

---

## Architecture

Gauntlet uses a narrow adapter pattern — the orchestration logic (seam.py) depends on interfaces, not on RAMPART or OpenShell directly:

```
cli.py
  └── seam.py (orchestration)
        ├── sandbox.py (SandboxAdapter interface)
        │     ├── FakeSandbox     — scripted fake for tests
        │     └── OpenShellSandbox — real OpenShell adapter
        ├── assurance.py (AssuranceAdapter interface)
        │     ├── FakeAssurance    — scripted fake for tests
        │     └── RampartAssurance — real RAMPART adapter
        └── report.py (structured report output)
```

This design lets you run the full seam with fakes in unit tests (no network, no real deps) and swap in real adapters for production runs — one flag or one constructor argument.

---

## Threat model

**The agent image is UNTRUSTED.** Gauntlet treats the agent under test as adversarial — it may attempt to escape its sandbox, exfiltrate data, or inject malicious content into reports.

Mitigations applied:

| Threat                                    | Mitigation                                                                                         |
| ----------------------------------------- | -------------------------------------------------------------------------------------------------- |
| Agent escapes sandbox                     | OpenShell enforces isolation at the kernel level (Landlock LSM + seccomp-bpf) — out-of-process     |
| Agent reaches host network                | Sandbox policy is deny-by-default for all network egress; no allowlist entries unless explicit     |
| Agent writes to host filesystem           | Sandbox policy is deny-by-default for filesystem access; only `/tmp` paths may be listed           |
| Agent injects secrets into report/logs    | All finding evidence is sanitized (Bearer tokens, sk- keys, GitHub/npm tokens, long opaque tokens) |
| Agent injects host paths into report/logs | Path patterns (3+ components) are redacted from all report output                                  |
| Seam code leaks credentials to agent      | `AssuranceAdapter.run()` has no credentials parameter; no secrets are injected into the sandbox    |
| Error messages expose host internals      | `SandboxError`, `AssuranceError`, and `SeamError` messages are sanitized before surfacing          |

**What is NOT mitigated here:**

- Vulnerabilities in the OpenShell sandbox itself (report to NVIDIA PSIRT: psirt@nvidia.com)
- Vulnerabilities in RAMPART (report to aisafetytools@microsoft.com)
- Attacks requiring a compromised host (kernel exploits) — these require host-level hardening outside Gauntlet's scope
- Multi-tenant isolation — OpenShell v0.0.46 is "single-player mode" (one developer, one environment)

**Credential discipline:** never pass API keys, tokens, or production credentials via environment variables when running Gauntlet against an untrusted agent. The `--policy` file must not contain secrets.

---

## Development

```bash
pip install -e ".[dev]"
pytest -v
```

Unit tests pass with no network and no real RAMPART/OpenShell. Integration tests skip cleanly when the dependencies are absent.

---

## Non-goals

Gauntlet is small by design. The following are explicitly out of scope:

- A hosted or managed runner (no SaaS, no Stripe billing)
- A standalone company or "the open assurance standard" — that direction is retired
- Competing with RAMPART or OpenShell
- Anything requiring a multi-tenant database or control plane
