High-discipline problem solving for bugs, coding, and architectural changes (/boostx). Uses a red gate, Ponytail anti-bloat ladder, dual-OS rules, and verification. Use when the user runs /boostx, or the task is a tricky bug, regression, or high-stakes code change. Do NOT use for copy-only writing, interview/planning (grill-me), or doc sync alone (use /update-doc).
