What

A monitor process that exits having emitted nothing now reports that specifically, rather than the generic stream-ended message.

Details
  • The exit code is appended to the no-output message.
  • The exit-code suffix is now shared across the completed and failed strings instead of being built separately.
Evidence

ended without producing output

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
