Certainty and Evidence Policy

Use this policy for all user-facing summaries.

Allowed Fact Sources

• Explicit user inputs in current request.
• Direct tool/runtime outputs observed in current task.
• Deterministic transformations of explicit values (for example unit conversion), when clearly traceable.

Disallowed as Final Facts

• Guesses based on typical defaults.
• Machine/runtime values not measured in the current task.
• Inferred values presented without explicit uncertainty.

Output Rules

1. If value is not verified, mark as unknown.
2. Ask one unblocker question for critical unknowns.
3. Do not mix inferred and verified data in the same fact line.
4. Preserve [assumption-based], inferred_*, pending_clarifications, and ready_for_builder: false markers received from k6-plan.
5. Do not promote exploratory planning metadata to confirmed runnable facts during generation.
6. Keep final summary concise and practical.
