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. DelayedStream.create wraps a source stream with default or custom options
  2. DelayedStream buffers events emitted by the source before resume is called
  3. DelayedStream flushes buffered events in chronological order on resume
  4. DelayedStream continues forwarding real-time events after release
  5. DelayedStream.prototype.pipe transmits buffered and incoming data to destination writable stream
  6. DelayedStream emits error event when buffered data exceeds maxDataSize limit
  7. DelayedStream.prototype.setEncoding proxies encoding settings to the source stream
