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_getCurrentPriorityLevel is exported as a function from scheduler
  2. unstable_getCurrentPriorityLevel returns unstable_NormalPriority (3) as default ambient priority level
  3. unstable_getCurrentPriorityLevel reflects priority level passed to unstable_runWithPriority during callback execution
  4. unstable_getCurrentPriorityLevel tracks nested priority scopes and restores previous priority on exit
  5. unstable_getCurrentPriorityLevel restores previous priority level when a callback throws an error
  6. unstable_getCurrentPriorityLevel inside a callback wrapped by unstable_wrapCallback reflects captured priority
