• Maintains historical record with clear context

---

7. QA Report Archived ✅

Original: /projects/Charon/docs/reports/qa_report.md Renamed to: /projects/Charon/docs/reports/qa_geolite2_checksum_fix.md

Reason:

• Archive QA verification report with descriptive name
• Makes room for future QA reports
• Maintains audit trail with clear identification

---

Files NOT Changed (Verified)

No Updates Required

✅ CONTRIBUTING.md — No Docker build instructions present ✅ Docker integration docs — Covers auto-discovery feature, not image building ✅ Development docs — No GeoLite2 or checksum references ✅ Troubleshooting docs — No outdated checksum references found

Old Checksum References (Expected)

The old checksum (6b778471...) is still present in:

• docs/plans/geolite2_checksum_fix_spec.md (archived implementation plan)

This is correct — the implementation plan documents the "before" state for historical context.

---

Verification Performed

1. Checksum Reference Search

grep -r "6b778471c086c44d15bd4df954661d441a5513ec48f1af5545cb05af8f2e15b9" \
  --exclude-dir=.git --exclude-dir=node_modules docs/

Result: Only found in archived implementation plan (expected)

2. Documentation Structure Check

tree docs/maintenance/

Result:

docs/maintenance/
├── README.md
└── geolite2-checksum-update.md

3. Link Validation

All internal documentation links verified:

• ✅ CHANGELOG → maintenance guide
• ✅ CHANGELOG → implementation plan
• ✅ CHANGELOG → QA report
• ✅ README → maintenance directory
• ✅ Maintenance index → GeoLite2 guide
• ✅ GeoLite2 guide → workflow file
• ✅ GeoLite2 guide → implementation plan
• ✅ GeoLite2 guide → QA report
