| Aspect | Guarantees | Implementation | |--------|------------|----------------| | | Fully lock‑free, memory‑consistent across threads. | Uses std::atomic for pointer/handle reads; no mutexes. | | Write | Exclusive access per arena. | Arena.mutate() acquires a spin‑lock ( std::atomic_flag ). Nested guards are re‑entrant. | | Multi‑process | Safe when using shared‑memory arena; readers see writes after the guard exits. | Memory barriers ( std::atomic_thread_fence ) inserted at guard exit. | | Atomic fields | view.atomic_int32 provides fetch_add , compare_exchange . | Implemented with std::atomic<int32_t> placed directly in the arena. | | Arena
