-## Refresh frozen fallback explanation tables
-
-When this release adds support for a new CUDA Toolkit version, check
-whether the CTK release added any new `CUresult` or `cudaError_t` codes.
-If so, update the frozen fallback tables so error messages stay
-informative for consumers on older `cuda-bindings` versions:
-
-- `cuda_core/cuda/core/_utils/driver_cu_result_explanations_frozen.py`
-- `cuda_core/cuda/core/_utils/runtime_cuda_error_explanations_frozen.py`
-
-The corresponding tests in `test_utils_enum_explanations_helpers.py`
-will fail if an entry is missing.

+# Do not update it past CUDA Toolkit v13.1.1. Bindings releases new enough to

+# cuGetErrorString(). Synchronizing this table with later Toolkit releases would
