"""Catalog of question types: the model picks a type and literal parameters, code builds and executes the plan. The instructions and few-shot demonstrations are optimized offline with DSPy (``python -m tools.answers.catalog_optimize``) on labeled questions in ``catalog_examples.json`` and stored in ``question_catalog.json``. At run time no DSPy is needed: the stored program is sent through the shared model client (deadline, fair gate). Parameters are checked against the question: a person, topic or exclusion that is not literally in it is dropped, never trusted. When the call fails or the type is unclear, the rule-based planner is the fallback. The model never writes a query; it only selects a route of the fixed catalog.
