Re-audit the files that were judged insufficient in the previous audit.

**Important:** Review the supervisor's verification results and understand:
- List of unaudited files
- List of files flagged as insufficiently audited
- Specific feedback

**Important:** Refer to the audit report: {report:02-audit-security.md}

**What to do:**
1. **Read each flagged file in full using Read tool one by one**
2. Review each file from a security perspective
3. Report discovered issues with severity ratings

**Output principles:**
- Preserve all existing results from the previous audit report, and integrate new results into a complete updated version
- Add newly audited files to the audit results

**Strictly prohibited:**
- Searching with Grep and only reviewing matching files → PROHIBITED
- Reading only part of a file → PROHIBITED
- Skipping a file because it "looks fine" → PROHIBITED
