A workflow agent that finished with nothing now raises a clear error instead of passing an empty result on.

What

In workflow v2 runs, an agent that was skipped, blocked, or gave up after retries used to pass its empty result along as a value. It now raises a descriptive error instead.

Details
  • Cleanup also sweeps retracted setup-script facts along with failed and finished ones.
Evidence

agent produced no result (skipped, blocked, or gave up after retries)

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