Let me create it.\n\nLet me think about each function carefully.\n\n1. roman_to_int: standard.\n\n2. merge_intervals: merge overlapping/touching closed intervals. Touching means [1,2] and [2,3] merge into [1,3]. Sort by start.\n\n3. lru_cache_sim: capacity, ops. Standard LRU. Return results of each get in order.\n\nEdge: capacity could be 0? Probably handle gracefully. Let's handle capacity <= 0: put does nothing, get returns -1.\n\n4. top_k_words: words are [a-z']+ runs, case-insensitive. So lowercase the text, find runs of [a-z']+. Count frequencies. Sort by (-count, word). Return top k words. Note: should we strip apostrophes? The spec says words are [a-z']+ runs. So \"don't\" is one word. Keep as is.\n\n5. parse_duration: parse \"1h30m\", \"45s\", \"2h\", \"1h2m3s\", \"90m\". Raise ValueError for \"\", \"h\", \"1x\", \"1h1h\". So format: sequence of number+unit pairs, units h, m, s, each unit at most once, must be in order h, m, s? \"1h1h\" invalid because repeated. \"1x\" invalid unit. \"h\" invalid no number. \"90m\" valid = 5400.\n\nShould we require order? \"1m1h\" \u2014 probably invalid. Let's enforce strictly descending order h > m > s. Also numbers must be non-negative integers? Let's allow digits only (no leading + or -). Probably require at least one digit. Let's use regex: ^(\\d+h)?(\\d+m)?(\\d+s)?$ and require non-empty match and at least one component.\n\nLet me write it.\n\nFor parse_duration, should \"0s\" be valid? Yes probably. Should \"1h0m\" valid? Yes.\n\nLet me write the solution and tests.\n\nFor merge_intervals: input list of [start, end]. Sort by start. Merge if next.start <= current.end (touching merges). Return list of lists.\n\nLet me write.\n\nFor top_k_words, k could be larger than number of unique words \u2014 return all. k <= 0 returns [].\n\nLet me write the file.", "tool_calls": [{"index": 0, "id": "chatcmpl-tool-a4d70cf5e48510c8", "type": "function", "function": {"name": "write_file", "arguments": "{\"path\": \"solution.py\", \"content\": \"\\\"\\\"\\\"Five small utility functions (Python 3 stdlib only).\\\"\\\"\\\"\\n\\nimport re\\nfrom collections import Counter, OrderedDict\\n\\n_ROMAN_VALUES = {\\n    \\\"I\\\": 1,\\n    \\\"V\\\": 5,\\n    \\\"X\\\": 10,\\n    \\\"L\\\": 50,\\n    \\\"C\\\": 100,\\n    \\\"D\\\": 500,\\n    \\\"M\\\": 1000,\\n}\\n\\n\\ndef roman_to_int(s: str) -> int:\\n    \\\"\\\"\\\"Convert a valid Roman numeral (I..MMMCMXCIX) to an int.\\\"\\\"\\\"\\n    if not isinstance(s, str) or not s:\\n        raise ValueError(\\\"invalid roman numeral\\\")\\n    total = 0\\n    prev = 0\\n    for ch in reversed(s.upper()):\\n        if ch not in _ROMAN_VALUES:\\n            raise ValueError(\\\"invalid roman numeral: %r\\\" % (s,))\\n        val = _ROMAN_VALUES[ch]\\n        if val < prev:\\n            total -= val\\n        else:\\n            total += val\\n            prev = val\\n    return total\\n\\n\\ndef merge_intervals(iv):\\n    \\\"\\\"\\\"Merge overlapping/touching closed intervals;
