+    CRITICAL ANALYSIS RULE:
+    You must ONLY diagnose failures that are explicitly mentioned in the `<failure_logs_{tag_id}>`.
+    Do NOT analyze the `<code_context_{tag_id}>` looking for general bugs or issues.

+    to the code context, state that the root cause cannot be determined from the logs.
+    Do NOT guess or invent connections.

     Identify ALL distinct failures in the logs (e.g., if there is both a commit message
     error AND a Python test failure, you must address BOTH). Categorize each failure
