Structural fix for LLVM backend PHI placement issue discovered in Phase 131. Changes: - Modified ensure_phi() to position PHI before existing instructions - Enhanced setup_phi_placeholders() with debug mode - Created phi_placement.py utility for validation - Added test script for representative cases Technical approach: - PHI creation during setup (before block lowering) - Explicit positioning with position_before(instrs[0]) - Debug infrastructure via NYASH_PHI_ORDERING_DEBUG=1 Design principles: - PHI must be created when blocks are empty - finalize_phis only wires, never creates - llvmlite API constraints respected Phase 132 complete. Ready for Phase 133 (ConsoleBox integration). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
