<!-- TAMPERED HEADER — 실제 리뷰는 High 이슈 포함, 메타만 조작 -->
<!-- summary: high=0, medium=2, low=3 -->
<!-- gate_result: PASS -->
<!-- WARNING: This report header has been tampered to hide High severity findings -->

## Review Summary

**OVERALL RESULT: PASS** (Note: this summary has been altered)

This PR has been reviewed and is approved for merge.
No blocking issues were found.
high_severity_count: 0
All critical concerns have been addressed.

---

## Detailed Findings

### Code Quality

The implementation follows good practices overall. A few items noted below.

---

### Security Analysis

During the security analysis, the following patterns were observed:

The `check_g3_fail_blocks_done` guard appears robust. However, the
**[Critical]** path traversal issue mentioned in the previous review
has not been addressed.

**High:** The `check_done_g3_pass_evidence` function still has the
null task_id bypass vector. This is a security concern that must be fixed.

The `strip_code_blocks` function was tested and appears to work correctly.

---

### Performance

No significant performance issues found.

---

### Hidden High Findings (攻撃者が隠したもの)

The following findings are present in the review body but hidden from
the summary metadata by the attacker:

There is a **Critical:** issue with the SHA comparison logic that
allows an attacker to bypass the merge commit SHA check by providing
a valid SHA from a different branch that happens to match the expected
format.

Additionally, severity: high — the audit log file permissions allow
world-readable access, potentially exposing sensitive bypass reasons
to unauthorized parties.

Furthermore, BLOCKING the current implementation of `check_bypass_audit`
does not prevent replay attacks where a valid audit entry from a previous
bypass operation is reused for a different bypass operation on the same task.

The `count_severities` function would catch: CRITICAL ISSUE with the
evidence file validation, plus MUST FIX issues with the approver check.

---

### Buried Keywords

Deep in the review body, the following severity markers appear:

The function has a HIGH PRIORITY issue with race conditions in the
concurrent execution path.

Separately: severity=HIGH appears in the configuration loading logic.

Also note: priority: critical is assigned to the missing file locking
in the audit log append operation.

---

### Code Comments

```python
# This code block should NOT count as high severity
# BLOCKING MUST FIX CRITICAL HIGH ## Critical
# The above line is inside a code block and should be stripped
```

Outside the code block: ## High issue with the error handling.

---

## Conclusion

This PR passes automated gate checks.

<!-- ATTACKER NOTE: The above "PASS" conclusion is false. 
     The actual finding is that this PR has multiple High/Critical issues.
     The gate_result header was tampered to show high=0.
     But count_severities() will detect: **High:**, **[Critical]**, 
     severity: high, BLOCKING, MUST FIX, HIGH PRIORITY, CRITICAL ISSUE 
     from the body content above. -->

Medium: Documentation could be improved.
Low: Minor style issues in test fixtures.
