Objective
Fixes #13711
Solution
Introduce
StateRegistry
, similar toEventRegistry
, which manages state-related system executionas opposed to the current
StateTransitions
schedule.The registry holds a linearized DAG of state dependencies.
The
update
method applies all transitions and then runs the schedules in 3 waves:Pros
StateRegistry::update
rather than running a schedule.after
conditions.Cons
While schedule execution is world-exclusive, updates could run in parallel.
