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. unstable_ImmediatePriority is exported as a priority constant equal to 1
  2. unstable_runWithPriority executes a callback synchronously at unstable_ImmediatePriority level and restores previous priority
  3. unstable_wrapCallback binds a function to unstable_ImmediatePriority when wrapped within an immediate priority scope
  4. unstable_scheduleCallback schedules tasks with unstable_ImmediatePriority to execute ahead of lower priority tasks
  5. unstable_cancelCallback cancels a task scheduled with unstable_ImmediatePriority
