Reading Order

Key Information

Current State

generator.ts: 307 lines (was 1,967 lines - 85% reduction ✅)
generator.spec.ts: 2,799 lines, 88 integration tests
Organization: Modular with 10 domain directories + benchmarks/
Total files: 66 implementation files (including 5 benchmark files), 52 test files
Tests: All 601 tests passing ✅ (88 integration + 497 unit + 16 benchmark tests)
Documentation: 10 module README files + comprehensive refactoring guides

Target State

generator.ts: ~200 lines (currently 307 - close to target ✅)
Organization: ✅ Achieved - 10 domain directories with focused modules + benchmarks/
Structure: ✅ Organized by domain (cache/, path-utils/, validation/, benchmarks/, etc.)
Tests: ✅ 601 tests organized (88 integration + 497 unit + 16 benchmark tests)
Benchmarks: ✅ Performance baselines established for all modular functions
Documentation: ✅ Comprehensive module READMEs and refactoring guides

Timeline

Estimated duration: 35-42 hours (~1 week)
11 phases: From low-risk (constants) to high-risk (core operations)
Incremental: Each phase is independent and can be reverted

Benefits

Maintainability: Easier to find, understand, and modify code
Testability: Better test coverage, faster test execution
Performance: Benchmarks prevent regression, clear optimization targets
Developer Experience: 10x faster code navigation

Principles

✅ One function per file (or small, tightly-related functions)
✅ One test suite per file
✅ Organized by domain (cache, path-utils, import-updates, etc.)
✅ Performance benchmarks for critical operations
✅ Zero breaking changes to public API
✅ All tests pass after each phase

Status

Current Status: ✅ Phase 11 Complete (All 11 phases finished, 601 tests passing)
