Error message

Ralph workflow returned a round failure without its last handoff

What it means

Thrown while decoding a Ralph workflow terminal result of kind 'round-failed'. The result object's keys were validated as exactly lastReport,roundsStarted,status, so this guard fires when the accompanying lastReport is absent or cannot be read: a round-failed outcome is required to carry the report of the round that failed so the caller can inspect what was attempted. The workflow provider returned a round failure without that evidence.

Solutions

1. Ensure a failed round still carries its last handoff in the result; fix the workflow's failure-result assembly.

When it happens

Trigger: Thrown at packages/workflow/tool-ralph/src/index.ts:322 when the library encounters an invalid state.

Common situations: See trigger scenarios.
