🎊 Phase 9.75g-0 COMPLETE - Revolutionary Plugin System Achievement\!
✅ Major Completions:
- plugin-tester type validation: nyash.toml integration & method signature verification
- Duplicate method name detection: Enforces Nyash no-overloading policy
- Comprehensive developer guide: 200+ line technical documentation
- Memory safety: HostVtable lifetime issues resolved with LazyLock
- Type information system: External nyash.toml configuration eliminates hardcoded conversions
🚀 Revolutionary Impact:
Nyash now supports dynamic Box type extension via plugins:
```nyash
local file = new FileBox() // Plugin-provided
local db = new PostgreSQLBox() // Future: Plugin-provided
local gpu = new CudaBox() // Future: Plugin-provided
```
📊 Technical Achievements:
- plugin-tester: 4 comprehensive validation modes (check/lifecycle/io/typecheck)
- BID-FFI Protocol: Production-ready with valgrind-verified memory safety
- Type conversion: Automatic string→bytes mapping via nyash.toml
- Method validation: Prevents overloading conflicts in plugin development
🎯 Next Priority: Phase 8.6 VM Performance Improvement
Current issue: VM is 0.9x slower than interpreter (regression\!)
Target: 2x+ speedup for practical VM execution

🚨 Critical memory safety fix:
- HostVtable was created on stack and destroyed after init
- Plugin stored reference to destroyed memory → NULL pointer access
- Changed to static LazyLock storage for lifetime safety
✅ Results:
- Segfault completely eliminated
- Plugin logging now works properly
- Type info system confirmed working
- Full E2E FileBox plugin operation successful
