Major additions:
- Phase 11.8 MIR cleanup specification (Core-15→14→13 roadmap)
- Nyash ABI unified design document (3×u64 structure)
- TaskGroupBox foundation with cancelAll/joinAll methods
- Enhanced async/await with checkpoint auto-insertion
- Structured concurrency preparation (parent-child task relationships)
Documentation:
- docs/development/roadmap/phases/phase-11.8_mir_cleanup/: Complete Core-13 path
- docs/development/roadmap/phases/phase-12/NYASH-ABI-DESIGN.md: Unified ABI spec
- Updated Phase 12 README with AOT/JIT explanation for script performance
- Added async_task_system/ design docs
Implementation progress:
- FutureBox spawn tracking with weak/strong reference management
- VM checkpoint integration before/after await
- LLVM backend async support preparation
- Verifier rules for await-checkpoint enforcement
- Result<T,E> normalization for timeout/cancellation
Technical insights:
- MIR as 'atomic instructions', Box as 'molecules' philosophy
- 'Everything is Box' enables full-stack with minimal instructions
- Unified BoxCall for array/plugin/async operations future consolidation
Next steps:
- Complete TaskGroupBox implementation
- Migrate from global to scoped task management
- Implement LIFO cleanup on scope exit
- Continue Core-13 instruction consolidation

Phase 11.7 – JIT Complete (MIR-15 + Semantics + Sync/Async GC)
Scope: Implement a production‑ready JIT backend for Nyash that fully supports the MIR Core‑15 instruction set, synchronous/async GC cooperation, and delivers a simple, reproducible developer experience across platforms (WSL/Linux/Windows).
Why now:
- LLVM AOT は一度実装を進めたが、Windows 依存が重くサイズも大きい。Cranelift に回帰して、純Rustで“Just Works”のDXを取り戻し、高速な反復開発を実現する(AOT/LLVMは資料として保持)。
Outcomes (Definition of Done):
- All MIR‑15 ops compile and execute via JIT with behavioral parity to VM.
- BoxCall/ExternCall are handled through NyRT shims (handle‑first ABI) safely.
- Sync GC barriers in place (read/write), async safepoints wired at call/loop edges.
- Smokes: echo/array/map/vinvoke/extern pass; parity checks vs VM/JIT (logs included).
- 1‑command setup and run on WSL + Windows Dev PowerShell; no external LLVM needed.
Backends Strategy:
- LLVM AOT はアーカイブ(参照は可)。主線は Cranelift(JIT/軽量AOT)。
- JIT 既定は Cranelift(feature:
cranelift-jit)。AOT は必要に応じcranelift-objectを併用。
This folder contains the living plan (PLAN.md) and the rolling snapshot of the current task focus (CURRENT_TASK.md). Semantics 層の導入により、Nyash スクリプト/VM/JIT(exe)の動作を一致させる。
