🎊 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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
