  "message": "fix: refuse a declared pair written without its inner parentheses\n\n`__post_init__` catches `udfs\u003dfn` written for `udfs\u003d(fn,)` so the error\nlands in the extension library\u0027s own frame rather than deep inside\n`with_extensions`. The pair-shaped fields have the same mistake one level\nin — `udtfs\u003d(\"expand\", fn)` is a two-element tuple, so it normalized\nwithout complaint and surfaced later as `\u0027function\u0027 object is not\nsubscriptable`, naming neither the field nor the bundle.\n\nMark those fields in the field metadata and check each item is a\n`(str, value)` pair, normalizing it to a tuple like everything else here.\nA str item is rejected before unpacking: a two-letter name would\notherwise unpack into two characters and pass.\n\nCo-Authored-By: Claude Opus 5 (1M context) \u003cnoreply@anthropic.com\u003e\n",
