selectors

Predicate functions for querying async-process state out of a Store snapshot.

notStarted, inProgress, done, successful, failed, retrying, restarting, halted, paused, and cancelled answer single-question predicates over a process state. derivedState returns the canonical phase string for a process so UI code can render a single source-of-truth label instead of testing each predicate. All selectors are pure and work over any state slice that conforms to the async-process shape; they are not tied to a specific store instance.
