All tests pass	100%	100% (601/601)	✅ Perfect
Test coverage	>95%	Not measured explicitly	⚠️ Needs verification
No performance regression	0 regressions	0 regressions	✅ Confirmed
generator.ts reduction	~90%	85% (1,967→307)	⚠️ Close but not met
All functions documented	JSDoc for all	Not verified	⚠️ Needs verification
All functions have tests	100%	100% (497 unit tests)	✅ Achieved
Critical paths benchmarked	Yes	Yes (16 tests)	✅ Achieved

Minor Gaps Identified:
