Purpose

Ask the smallest useful question that only the human modeler can answer. Present mutually exclusive options with consequences; do not turn mechanical checks into user questions.

Inputs

• Current gate and the judgment it needs.
• Problem goal, required output, hard constraints, and available evidence.
• planning/session_config.json.
• Existing decisions in methods/Qx/qx_decisions.jsonl.

Configuration

• Read interaction_mode; accept legacy mode for compatibility.
• learning: show 2–3 short questions and withhold the AI suggestion until the user answers.
• speed: show one compressed question and optionally show the AI suggestion alongside.
• rigor_profile does not change who owns the judgment.
