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. runParallel executes an array of async functions concurrently and returns results in an ordered array
  2. runParallel executes an object of named async functions concurrently and returns results in a keyed object
  3. runParallel invokes callback with error immediately when any task fails and ignores later results
  4. runParallel handles empty array and empty object tasks by invoking callback with empty results
  5. runParallel handles synchronous task execution via queueMicrotask deferral
