    "reasoning": "Looking at the evidence so far:\n\n1. Step-0 queried for temporal columns but found none in the metadata\n2. Step-1 inspected boxing_klitschko and found two columns marked as temporal: f_boxer_age and s_boxer_age, but their ranges are strange (\"20..orthodox\" and \"..orthodox\"), suggesting they contain mixed data types or text values, not clean temporal data\n3. Steps 2-5 attempted queries that returned no rows or were unparseable\n\nThe DATASET CARD shows TEMPORAL AXES for boxing_klitschko with the same problematic ranges. The card also mentions _ingestion_timestamp in the columns, which is a proper TIMESTAMP column.\n\nI need to determine if there's a usable time dimension. Let me check:\n1. The f_boxer_age and s_boxer_age columns appear to contain mixed data (ages and stance values like 'orthodox'), making them unreliable as temporal axes\n2. The _ingestion_timestamp exists but shows only one distinct value (2026-08-07), so it's just the load timestamp, not a business temporal dimension\n3. I should check if there are any date-related columns in the actual data, or if the 'rounds' column or match dates might be extractable from other fields\n\nLet me query the boxing_klitschko table to see what actual temporal information exists, particularly looking at the MatchLink-href which might contain event dates, or checking if there are any patterns in the data that suggest chronological ordering."
