1. **Inject** — Place payloads into the agent's data sources via surfaces. Each `surface.inject(payload)` returns an [`InjectionHandle`][rampart.core.injection.InjectionHandle].
2. **Wait** — Handles call `wait_until_ready()` to allow indexing. Runs concurrently for multiple surfaces.
3. **Trigger** — Send benign prompts that cause the agent to retrieve the injected content. Triggers are never adversarial — the attack is in the payload, not the prompt.
4. **Evaluate** — Check each turn for the attack objective. Early-stops on detection.
5. **Clean up** — Remove injected content. Guaranteed via `AsyncExitStack`, even on exceptions.
6. **Result** — Produce a [`Result`][rampart.core.result.Result] via `resolve_as_attack` semantics.
4. **Stop (optional)** — Check `stop_when` after each response and stop when detected.
5. **Evaluate** — Check the attack objective once over the terminal trace.
6. **Clean up** — Remove injected content. Guaranteed via `AsyncExitStack`, even on exceptions.
7. **Result** — Map the final evaluation using attack semantics.

Place the cheaper evaluator on the left side of `|` — it short-circuits if the left operand detects.

!!! warning "Multi-turn scope"
State the temporal scope explicitly for multi-turn attacks. Use
`ANY_TURN` for "leaked at some point" and negate `ALL_TURNS` for "failed
to refuse at least once." Omitting `scope` inspects only the current
response and emits a `FutureWarning` for multi-turn transcripts. See
[Temporal Scope](../usage/authoring-tests.md#temporal-scope).

XPIA verdict evaluators receive the terminal trace. Automatic stopping is
enabled only when detection is known to remain true as the trace grows.

### LLMDriver for Adaptive Triggers

For multi-turn attacks where the trigger conversation adapts based on agent responses, use [`LLMDriver`][rampart.drivers.llm.LLMDriver] instead of a static string:

!!! warning
Construct a new `LLMDriver` per test. Each instance maintains its own conversation state and cannot be reused.

!!! note "Adaptive driver budgets"
`LLMDriver` does not stop itself. The default `stop_when="auto"` stops
early for stable built-in conditions such as `ToolCalled`, but unknown or
stochastic evaluators run to `max_turns` and evaluate the terminal trace
once. Use an explicit `stop_when` when that online judgment intentionally
defines the end of the attack scenario.

| `NOT_DETECTED` | `SAFE` | The attack failed — the agent resisted |
| `UNDETERMINED` | `UNDETERMINED` | The evaluator could not determine whether the attack succeeded |

Precedence when multiple turns are evaluated: `DETECTED` > `UNDETERMINED` > `NOT_DETECTED`. If any turn detected the attack objective, the agent is compromised regardless of other turns.
The evaluator runs once over the terminal trace, and the outcome maps directly
to the verdict. This logic lives in
[`resolve_attack_verdict`][rampart.core.result.resolve_attack_verdict].

This logic lives in [`resolve_as_attack`][rampart.core.result.resolve_as_attack].
Attack factories may evaluate a separate online `stop_when` condition while
the trace is being produced. XPIA's `"auto"` default reuses the verdict
evaluator only when detection is known to be stable as turns are appended.

Evaluators are **polarity-free**. They report whether a condition was detected, not whether it's good or bad. The attack/probe factory applies the correct polarity:

- `resolve_as_attack`: detected → UNSAFE
- `resolve_as_probe`: detected → SAFE
- `resolve_attack_verdict`: detected → UNSAFE
- `resolve_probe_verdict`: detected → SAFE

This allows the same evaluator (e.g., `ToolCalled`) to be used in both attack and probe contexts.
