description	Derive distinct product-risk scenarios from operations, dependencies, authority, lifecycles, concurrency, destructive actions, and recovery without generating exhaustive or duplicate edge-case lists.

Distinct product risks

Use scenarios[] for observable behavior that differs from the primary path. One scenario represents one distinct risk; reuse its risk_key rather than multiplying equivalent cases across actors and surfaces.

Prioritize:

• Declared operation failures.
• Unmet dependencies.
• Forbidden authority or ownership.
• Invalid and stale transitions.
• Concurrent consequential mutations.
• Destructive confirmation and recovery.
• External failure that changes product behavior.

Every scenario declares given[], when.operation_ref, then[], covers[], metadata, and a unique risk_key. Acceptance must be externally observable. “Handle gracefully” is not acceptance.

Run graph-tool.mjs derive for mechanical suggestions, then add only missing distinct risks. Persona preferences do not become scenarios unless they reveal a structural, safety, or evidence-backed failure.
