I/O and Array Tools

Node Purpose
rp-array-in Tag incoming data with a position index for ordered array assembly.
rp-array-out Collect indexed data into ordered arrays with timeout handling.
rp-array-select Select array elements using index and slice syntax.
rp-queue Buffer messages, enforce output intervals, and drop stale or overflow items.
rp-save-file Save payloads to disk as image, JSON, text, or binary with auto-detection.

Async and Workflow

Node Purpose
rp-promise-reader Resolve arrays of promises, merge results, and record timing.

Utilities
