What it means

A pipe declares an input that nothing it runs reads.

What to do

Remove each of params.variables from the pipe's inputs, or read it where it was meant to be read. The item's suggested_fix may carry the removal.

Next steps

A problem carries the step aimed at whoever reads it: the first when its reader is the domain's actor, the method's author, and the second for any other reader.

Reader	Kind	Detail
The domain's actor	`change_method`	Remove the inputs pipe '`{pipe}`' never reads, or read them, then validate the method again.
Any other reader	`contact_owner`	Ask the method's owner to remove the inputs pipe '`{pipe}`' never reads.
