## Summary Implemented fail-fast validation for PHI ordering and value resolution in strict mode. ## Changes ### P1-1: Strict mode for "PHI after terminator" - File: `src/llvm_py/phi_wiring/wiring.py::ensure_phi` - Behavior: `NYASH_LLVM_PHI_STRICT=1` → RuntimeError if PHI created after terminator - Default: Warning only (no regression) ### P1-2: Strict mode for "fallback 0" - File: `src/llvm_py/phi_wiring/wiring.py::wire_incomings` - Behavior: Strict mode forbids silent fallback to 0 (2 locations) - Location 1: Unresolvable incoming value - Location 2: Type coercion failure - Error messages point to next debug file: `llvm_builder.py::_value_at_end_i64` ### P1-3: Connect verify_phi_ordering() to execution path - File: `src/llvm_py/builders/function_lower.py` - Behavior: Verify PHI ordering after all instructions emitted - Debug mode: Shows "✅ All N blocks have correct PHI ordering" - Strict mode: Raises RuntimeError with block list if violations found ## Testing ✅ Test 1: strict=OFF - passes without errors ✅ Test 2: strict=ON - passes without errors (no violations in test fixtures) ✅ Test 3: debug mode - verify_phi_ordering() connected and running ## Scope - LLVM harness (Python) changes only - No new environment variables (uses existing 3 from Phase 277 P2) - No JoinIR/Rust changes (root fix is Phase 279) - Default behavior unchanged (strict mode opt-in) ## Next Steps - Phase 278: Remove deprecated env var support - Phase 279: Root fix - unify "2本のコンパイラ" pipelines 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
