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. pLimit restricts concurrent execution of async tasks to the specified concurrency threshold
  2. limit exposes activeCount and pendingCount properties reflecting real-time queue state
  3. limit.clearQueue empties pending queued tasks while allowing active tasks to complete
  4. limit passes through arguments to the wrapped async function and resolves with the return value
  5. pLimit throws a TypeError when initialized with invalid concurrency values
