  "message": "[modernize] Modernize AutoDiff and NumericDiff CostFunctions to C++17\n\nModernize the construction and initialization logic of AutoDiffCostFunction,\nNumericDiffCostFunction, AutoDiffFirstOrderFunction,\nNumericDiffFirstOrderFunction, DynamicAutoDiffCostFunction,\nDynamicNumericDiffCostFunction, and CostFunctionToFunctor by utilizing\nC++17 features:\n\n- Simplify constructor delegation using if constexpr, removing the need for\n  internal InitTag structures.\n- Use std::is_constructible_v for cleaner SFINAE in variadic constructors.\n- Add static_assert to catch improper usage of DYNAMIC residuals/parameters\n  at compile-time.\n- Add Ownership support to AutoDiffFirstOrderFunction,\n  DynamicAutoDiffCostFunction, and DynamicNumericDiffCostFunction.\n- Simplify CostFunctionToFunctor::operator() using variadic parameter packs.\n- Use this-\u003enum_residuals() for consistent and clear access to base class\n  state.\n- Minor code quality improvements and removal of redundant template\n  parameters.\n\nChange-Id: Id760a26ba2ceca4fb2939ef7632f2f1d9cc430c9\n",
