+# Independent review of the autonomous candidate
+
+An independent reviewer rejected your candidate pending correction. Read the
+current diff and `BOOK_SELF_EVOLUTION_REPORT.md`, then address this exact finding
+without expanding scope:
+
+The real production path in
+`agent.agent_runtime_helpers.convert_to_trajectory_format()` persists tool
+results as one or more XML-wrapped JSON objects, for example:
+
+```text
+<tool_response>
+{"tool_call_id": "...", "name": "...", "content": {"success": false}}
+</tool_response>
+```
+
+`derive_trajectory_signals()` currently attempts `json.loads()` on the entire
+wrapped value, so it reports zero tool errors for a real failed tool result.
+The existing synthetic test uses bare JSON and therefore misses this
+production/test-parity defect.
+
+Derive conservative signals from the actual converted ShareGPT trajectory,
+including multiple bundled `<tool_response>` entries and nested `content`.
+Fail closed on malformed or unsupported shapes. Add an end-to-end behavior test
+that passes a production-shaped internal assistant/tool exchange through the
+real conversion path before saving and verifies the resulting failure signal.
+Preserve the original trajectory messages byte-for-byte and keep the metadata
+backward-compatible.
+
+Run the focused tests, the existing trajectory-compressor tests, compilation,
+and `git diff --check`. Update the report with this review round and exact
+results. Do not claim downstream benefit without the separate ablation campaign,
+do not push or commit, and do not edit the book repository.
