// Phase 286 P2: Pattern2 → Frag PoC minimal fixture
//
// Purpose: Test Pattern2 (Loop with Conditional Break) using Plan/Frag SSOT
// Expected output: 42
//
// Structure:
//   i = 0, result = 0     // pre-loop init
//   loop(i < 2) {         // loop variable condition (avoids Phase143 normalized shadow)
//       if (i == 1) {     // conditional break (Pattern2 essence!)
//           result = 42
//           break
//       }
//       i = i + 1         // loop variable update
//   }
//   return result         // return updated value (42)
//
// PoC Goal:
//   Pattern2 → DomainPlan → CorePlan → Frag → emit_frag()
//   (Skip: JoinIR → bridge → merge)
//
// Design Note:
//   - loop(i < 2) instead of loop(true) to avoid Phase143 shadow routing
//   - has_break=true, has_continue=false → Pattern2Break classification
