-# Code Review: fix-verdict-pass-inference
-
-## Summary
-Replaces fragile substring search with structured-line parsing, matching the dashboard's existing `parse_verdict_status()` approach.
-
-## Findings
-- **Correctness**: `_parse_verdict_status_line()` correctly looks for `## Status:` and `- **Status**:` headers, extracting the value after the colon. The `after_colon.upper()` comparison handles case variations.
-- **Consistency**: The new helper mirrors `automaton/dashboard/core/task.py:parse_verdict_status()` — good alignment between enforcement layers.
-- **Fallback**: Unparseable verdicts now return `"human_intervention"` instead of the old behavior (which would have returned `human_intervention` for anything without "PASS"). This is a safe default.
-- **Edge case**: A verdict with `## Status: PASS` and "FAIL" in body correctly returns `complete` — the structured parse only looks at the status line.

-## Verdict
-APPROVED — no issues found.
