Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. scheduler exports unstable_NormalPriority as a numeric priority constant with value 3
  2. unstable_getCurrentPriorityLevel returns unstable_NormalPriority as the default ambient priority level
  3. unstable_runWithPriority executes a function within the scope of unstable_NormalPriority and returns its result
  4. unstable_runWithPriority restores the previous priority level after execution finishes or throws
  5. unstable_scheduleCallback schedules a task with priorityLevel set to unstable_NormalPriority and standard 5000ms timeout
  6. unstable_scheduleCallback executes normal priority tasks after immediate priority tasks and before low priority tasks
  7. unstable_wrapCallback captures unstable_NormalPriority and preserves it when invoked from other priority scopes
  8. unstable_cancelCallback cancels a task scheduled with unstable_NormalPriority
