Overview

Turns a job's stored payload into the one part of it a list row wants: the actual job arguments.

What Solid Queue stores is the whole ActiveJob serialization — {"job_class":…,"job_id":…,"queue_name":…,"arguments":[…],…} — so a raw preview is almost entirely boilerplate that is identical on every row. The job detail page still shows the full payload, where it is genuinely useful.

The input is a byte prefix truncated by SQL, so the JSON is usually cut off mid-value. Parsing is lenient by design: extract what is there, and fall back to the raw prefix rather than showing nothing.
