swiftData Race Undefined Behavior vs. False Sharing: Separating Concurrent-Only Latency Causes in C11 Handlers
Concurrent-only latency in a C11 request handler C11 defines a data race as undefined behavior: two threads access the same memory location, at least one access is a write, and no synchronization orders the operations. Compilers may then optimize as if the race cannot happen, so documented outcomes range from stale reads to non-terminating loops. This raises
cBevy 0.13 raw World resource access bypasses scheduler exclusivity enforcement
In Bevy 0.13 and later, the ECS scheduler enforces exclusive mutable access for resources when a system declares ResMut<T> . However, calling World::resource_mut<T>() directly outside a system—such as in startup code, custom threads, or async tasks—appears to fall outside that scheduler arbitration. The goal is to determine what diagnostics or sy
