## Summary Completed Phase 170-D-impl-4: Comprehensive documentation and test verification for LoopConditionScopeBox infrastructure. All four implementation phases (1-4) now complete with full modular Box-based architecture and thorough test coverage. ## Changes ### New Documentation - **phase170-d-impl-design.md** (1,356 lines): Comprehensive design document - Architecture overview and modular components - Detailed implementation summary for all 4 phases - Test results and verification procedures - Architecture decisions (Box Theory, Fail-Fast, Conservative Classification) - Future work for Phase 170-D-E and Phase 171+ ### Updated Documentation - **CURRENT_TASK.md**: Added Phase 170-D completion section - Full status overview - Completed work breakdown - Test verification results - Commit history - Architecture summary ## Implementation Status ### Phase 170-D-impl Complete Summary **Phase 170-D-impl-1** ✅ - LoopConditionScopeBox skeleton (220 lines) - CondVarScope enum and data structures - Public API design **Phase 170-D-impl-2** ✅ - Minimal analysis logic (317 lines) - Pure functions: extract_all_variables, is_outer_scope_variable - 12 comprehensive unit tests **Phase 170-D-impl-3** ✅ - Pattern 2/4 integration - Fail-Fast validation checks - 4 integration tests in loop_with_break_minimal.rs **Phase 170-D-impl-4** ✅ - Design documentation - Test verification and results - Architecture guide ### Module Structure ``` src/mir/loop_pattern_detection/ ├── mod.rs (201 lines) ├── loop_condition_scope.rs (220 lines) └── condition_var_analyzer.rs (317 lines) Total: 738 lines ``` ### Test Results ✅ Unit Tests: 16 total (12 in condition_var_analyzer + 4 in loop_with_break_minimal) ✅ Integration Tests: 2 verified (Pattern 2 accept/reject cases) ✅ Build: cargo build --release (0 errors, 50 warnings) ✅ Verification: NYASH_JOINIR_STRUCTURE_ONLY=1 tests pass ## Architecture Highlights - **Box Theory**: Clear separation of LoopConditionScopeBox (orchestration) and condition_var_analyzer (pure functions) - **Fail-Fast**: Early error detection before JoinIR generation - **Conservative Classification**: Defaults to LoopBodyLocal for unknown variables - **Reusable**: Pure functions independent and composition-friendly ## Future Work Phase 170-D-E: Advanced Patterns (Pattern 5+) - Support loop-body-local variables in conditions - Expanded scope heuristics - Selective pattern detection Phase 171: Condition Environment Integration - Tighter coupling with condition_to_joinir - Enhanced variable mapping 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
