+# Verdict: fix-verdict-parsing
+
+## Status: PASS
+**Completion Date**: 2026-06-14
+
+## Summary
+Fixed the critical verdict parsing bug and aligned the state machine with the orchestrator specification. All 90 tests pass. The false-BLOCKED issue where PASS verdicts mentioning "FAIL" or "NEEDS_REVIEW" were misclassified is resolved. The state machine now correctly maps IMPLEMENTATION.md alone to Bug Find and ADVERSARIAL_BUG_REPORT alone to Bug Find (matching the orchestrator spec).
+
+## Findings
+- All 29 task state tests pass (16 new + 13 existing, 1 updated)
+- Full suite: 90/90 passed
+- `py_compile` clean, `bash -n` clean
+- Structured verdict parsing with substring fallback works correctly for all edge cases tested
+- Filesystem task name validation added (skips directories with invalid characters)
+
+## Tasks for Review / Tie-Breaks
+- None
+
+## Remaining Issues
+- `prompts/referee.md` should document the required `## Status:` format (noted in DOC_REVIEW, to be addressed in fix-prompt-consistency task)
+
+## Score
