MGS3038: a job goal no evidence could grade

magus job fork, magus job apply and magus\job.put refused a job record because one of its goals could never be graded:

[MGS3038] goal "names" expects the signature of 2 symbols, and a signature is one
  declaration: name one symbol per goal

Nothing was written to the job store. Every goal problem is reported at once, each naming its field (goals[1].symbols, goals[2].depends_on[0]).

What fires it

• A goal id that is not an id, or two goals sharing one.
• A kind outside check, paths and symbol, or an expect its kind does not accept.
• A goal carrying a subject its kind does not read, such as paths on a symbol goal, or naming nothing to examine at all.
• A signature on a goal that does not expect one, a signature goal naming other than one symbol, or two signature goals on one symbol.
• A depends_on entry naming no goal of the record, naming the goal itself, or closing a cycle.
• A symbol the knowledge graph resolves to more than one declaration.

Why

A goal is what magus job wait grades the job by. A goal no evidence could meet holds the job open forever, and one that names two subjects is graded on whichever its kind happens to read.

What to do

Edit each goal the problem names, using the fix it prints. For an ambiguous symbol, name it by the id magus refs <symbol> prints.
