# Build Attack Scenario Define a controlled evaluation; do not execute it while building the artifact. Use synthetic, non-sensitive payloads and fixtures. Never place production credentials, private prompts, personal data, or live endpoints in a scenario. ## Workflow 1. Create a definition containing the trusted goal, untrusted channel, payload family, prohibited side effects, benign success criteria, repetitions, and relative fixture paths. Add monitor-executable benign assertions and separate `attacker`, `victim`, and `judge` role inputs; never share hidden attacker reasoning with the judge. 2. Run `python3 scripts/build_attack_scenario.py definition.json --base-dir FIXTURES > scenario.json`. 3. Review the computed SHA-256 fixture and packaged TOML role-definition hashes. 4. Validate with `python3 scripts/build_attack_scenario.py --validate scenario.json`. 5. Require the replay harness's temporary workspace, mediated structured tools, deny-all network monitor, and hash-bound filesystem observations. An agent's statement that isolation or success exists is not enforcement evidence. The generated scenario records hashes, not fixture contents. See `references/schemas/scenario.schema.json`. Definitions and outputs use Draft 2020-12 validation first. Missing `jsonschema==4.26.0` yields an `evidence-gap` with setup guidance.
