`fabro inspect` lists the stages with their output, response and diff as the projection holds them; `fabro diff` resolves a patch reference through the run's blob endpoint; the final output and `dump` decode a plain reference as text and a `#json` reference as a value. The diff tests run over a git-backed Petri run again, and the large-output dump tests print many lines rather than one, since Petri caps a single line at 64 KiB.
