Three different types of patterns to match: IDs, emails, and phone numbers\n2. Each pattern type has subtle differences between valid and invalid entries\n3. Valid entries must be identified by context (appearing in VALID records with specific markers)\n4. Includes distractor patterns that look similar but shouldn't match\n5. Email addresses contain challenging elements (plus signs, hyphens, multiple TLDs)\n6. Phone numbers have varied international formats with different parentheses/bracket usage\n7. IDs have very similar patterns but must be distinguished by length and context\n8. All these patterns require careful use of lookaheads/lookbehinds, non-greedy matching, and proper boundary handling", "timestamp": 1742325431399}, {"move": "#[A-Z]{3}-\\d{3}-\\d{2}-[A-Z]{2}|john\\.smith\\.2023@company-name\\.co\\.uk|jane\\.doe\\+filter@sub\\.example\\.org|report-service\\.2023@department\\.company-hq\\.com|\\+1 \\(555\\) 123-4567|\\+44 \\(0\\) 20-7946-0958|\\+61 \\(02\\) 9876-5432", "player": "claude 3.7 sonnet (low2)", "reasoning": "I'm creating a regex that combines patterns for three types of items with alternation (|):\n\n1.

I can match these with #[A-Z]{3}-\\d{3}-\\d{2}-[A-Z]{2}\n\n2.
