-# Verdict: fix-prompt-consistency
-
-## Status: PASS
-**Completion Date**: 2026-06-14
-
-## Summary
-Fixed prompt consistency issues: added mandatory stop conditions to bug_finder.md and adversarial_bug_find.md, fixed deprecated task path in onboarding.md, and expanded the prompt path regression test to catch concrete deprecated path patterns.
-
-## Findings
-- All 116 tests pass
-- `bug_finder.md` now has `## Stop Condition (MANDATORY)` with CONTRACT_MET requirement
-- `adversarial_bug_find.md` now has `## Stop Condition (MANDATORY)` requiring ADVERSARIAL_BUG_FIND_COMPLETE output
-- `onboarding.md:67` uses canonical `{project}/.automaton/tasks/onboarding/` path
-- `test_prompt_paths.py` catches both literal `{task-name}` and concrete deprecated paths
-
-## Tasks for Review / Tie-Breaks
-- None
-
-## Remaining Issues
-- `prompts/referee.md` should document required `## Status:` format for verdicts (to be addressed separately if needed)
