//! Exposes registry-backed task state to runtime callers without the command queue.
//!
//! [`SupervisorHandle`](crate::SupervisorHandle) uses these reads for membership and current-attempt queries.
//! Membership comes from the registry.
//! Physical activity combines registry activity bits with force-aborted attempts that remain active after membership ends.
