Get task data or status

Resulting data once completed. For bulk runs this is an array aligned to the inputs: one element per input, in the same order they were submitted, with null for inputs that returned no data (len(data) equals the number of inputs, and data[i] is the result for input i). A single (non-bulk) run returns the result object directly.

Why the task returned no data. A clean miss reads "No matching data found for this input." — for waterfalls followed by the providers that were tried. A bulk run returns one message per input, in input order.

Per-step account of a flow run, returned only when the request asks for it with include_trace=true. Shaped like data: one object for a single run, and for a bulk run a list aligned to the inputs, where trace[i] is the run for input i (null if no run can be attributed to that input). A bulk trace is always a list, never a single object. Omitted for enrichment and waterfall tasks, which have no steps to report, and for bulk runs started before per-input traces were recorded, whose runs can't be matched to their inputs.
