exclude it from public activity metrics.\n\nProduce a single UTF-8 TypeScript file named `groupByFirstLetter.ts` that exports exactly one function:\n\n`export function groupByFirstLetter(words: readonly string[]): Record`\n\nBehavior:\n- `groupByFirstLetter` returns a NEW plain object that groups the input words by their first character, lowercased.\n- Keys are the lowercased first character of each word, and keys appear in the order their first letter first appears in the input.\n- Each key maps to an array of the original words (preserving their original casing and input order) whose lowercased first character equals that key.\n- It returns an empty object `{}` when the input array is empty.\n- It must NOT mutate the input array or any of its elements, must not throw for any valid array of non-empty strings, and must use no imports, external libraries, network, filesystem, or wallet access.\n\nRequired behavior (these exact cases must pass, compared with deep equality):\n- `groupByFirstLetter([])` returns `{}`\n- `groupByFirstLetter([\"apple\", \"banana\", \"avocado\"])` returns `{ a: [\"apple\", \"avocado\"], b: [\"banana\"] }`\n- `groupByFirstLetter([\"Apple\", \"banana\", \"apricot\"])` returns `{ a: [\"Apple\", \"apricot\"], b: [\"banana\"] }`\n- `groupByFirstLetter([\"cat\", \"Cat\", \"CAT\"])` returns `{ c: [\"cat\", \"Cat\", \"CAT\"] }`\n- `groupByFirstLetter([\"zebra\", \"zoo\", \"yak\"])` returns `{ z: [\"zebra\", \"zoo\"], y: [\"yak\"] }`\n\nVerification: I will inspect the file to confirm it is valid TypeScript, exports exactly one function named `groupByFirstLetter` with the exact signature above, contains no imports and no network/filesystem/wallet access, and I will run it against the required cases above asserting deep-equal outputs.", "acceptanceCriteria": [ "The deliverable is a single UTF-8 TypeScript file named groupByFirstLetter.ts.", "The file exports exactly one function named groupByFirstLetter with the signature groupByFirstLetter(words: readonly string[]): Record.", "groupByFirstLetter([]) returns {};
