Purpose

Construct a strong countercase or alternative to an assumption and assess the consequence if it fails.

Input contract

required: [assumption, claim_or_decision, supporting_evidence]
optional: [alternative_worlds, dependency_graph, challenge_mode]
constraints: [separate assumption, countercase, evidence, and impact]

Procedure

1. State the assumption's role and dependencies in the target claim.
2. Build the strongest evidence-backed countercase and at least one alternative assumption.
3. Propagate consequences through dependent claims and identify discriminating observations.
4. Rate threat severity and confidence using the caller's scale.
