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. parallel runs asynchronous tasks concurrently over an array and preserves result indexing
  2. parallel runs asynchronous tasks concurrently over an object preserving keys
  3. serial runs asynchronous tasks sequentially in order over an array
  4. serial runs asynchronous tasks sequentially over an object
  5. serialOrdered runs tasks in sequence ordered by ascending comparator
  6. serialOrdered runs tasks in sequence ordered by descending comparator
  7. error in task stops execution and returns partial results to callback
