Eliminate "2本のコンパイラ" problem by unifying type propagation into single SSOT entry. SSOT implementation: - src/mir/type_propagation/pipeline.rs - SSOT type propagation pipeline - TypePropagationPipeline::run() - Single entry point for all routes Pipeline steps (fixed order): 1. Copy propagation (initial) 2. BinOp re-propagation (numeric promotion: Int+Float→Float) 3. Copy propagation (propagate promoted types) 4. PHI type inference (private step - cannot bypass) Callers (both routes now use SSOT): - lifecycle.rs::finalize_module() - Builder lifecycle route - joinir_function_converter.rs::propagate_types() - JoinIR bridge route Fail-fast guard (structural guarantee): - PHI type inference is private step inside TypePropagationPipeline - lifecycle.rs and joinir_function_converter.rs cannot call PhiTypeResolver directly - Only public API: TypePropagationPipeline::run() - Order drift is structurally impossible (private encapsulation) Code reduction: - ~500 lines of duplicate BinOp re-propagation logic removed - 2 implementations consolidated into 1 SSOT Files changed: - New: src/mir/type_propagation/mod.rs - New: src/mir/type_propagation/pipeline.rs (~300 lines) - Modified: src/mir/mod.rs - Modified: src/mir/builder/lifecycle.rs (~400 lines removed) - Modified: src/mir/join_ir_vm_bridge/joinir_function_converter.rs (~100 lines removed) Regression testing: ✅ Lifecycle route (VM backend): Phase 275 fixture ✅ JoinIR route (VM backend): loop_min_while.hako ✅ LLVM harness: Phase 275 fixture 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
