  "message": "Raise `FrozenInstanceError` when re-calling `__init__()` on a frozen message in pure Python.\n\nCalling `__init__()` on an existing message resets and reinitializes it. For a frozen message (e.g. one returned by `GetOptions()`), the C++ and upb implementations raise `FrozenInstanceError`, but pure Python silently cleared and modified it, because its `__init__()` did not check `_frozen`. Now all three implementations raise.\n\nPiperOrigin-RevId: 1015074692\n",
