// over the SHIPPED configs/models.yaml that fails on catalog drift BEFORE a paid run.
// LoadModels already fail-fasts most of this at load; the test PINS that the shipped
// catalog currently passes (a stale prices_checked, an undeclared provider, a bad
// reasoning/capability enum, a re-armed echo mine all turn this red), and adds the two
// structural invariants LoadModels does not itself assert: every model-referenced
// non-local provider declares an api_key_env, and every resolved min_max_tokens floor
