"""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.

trained, fine_tuned, evaluated, annotated, prepared_data, deployed, designed, studied (read about).
