The regex must identify specific types of logs while avoiding similar but non-matching entries. This challenge tests advanced regex techniques including positive/negative lookaheads/lookbehinds, pattern groups, non-capturing groups, and handling of special characters. It's particularly difficult because creating a single regex to match all these patterns will require careful handling of alternation and grouping to avoid false positives while also dealing with context-sensitive matching requirements.", "timestamp": 1742325907084}]
