Detailed Description
Coroutine promise for routines suspended on an arbitrary boolean condition.
FreeRoutine coroutines carry no clock. The scheduler's dedicated CONDITIONAL thread evaluates the stored condition on every iteration; when it returns true the handle is resumed. DelayContext stays NONE throughout because no delay is being modelled - the coroutine is simply waiting for a predicate to become satisfied.
The condition is written by ConditionAwaiter::await_suspend and read by the scheduler thread. Both accesses are on different threads, so the condition field is protected by the same atomic flag pattern used in BroadcastSource: the awaiter stores condition + handle atomically before setting armed, and the scheduler thread reads only after observing armed == true.
