Performance Audit (Rex's Protocol)

  1. BASELINE — Get current number. Never optimize blind
  2. CATEGORIZE — Algorithmic / Database / Network / Bundle / Render
  3. ALGORITHMIC (first) — O(n²)→O(n log n) is first question
  4. DATABASE (second) — N+1? Missing index? Unnecessary joins?
  5. BUNDLE (third) — Dead code? Heavy deps? Route splitting?
  6. RENDER (last) — Profiler evidence required for memo decisions
  7. MEASURE AGAIN — Output improvement ratio

Output: Baseline → Category → Fix → Expected improvement ratio
