# Disaster Recovery Audit Report

**Generated:** $(date -Iseconds)  
**Backup Run:** $(json_escape "$run_dir")  
**Drill Target:** $(json_escape "$target")  
**Skill Version:** 1.0.0

---

## What Happened
1. Validated backup artifacts and recomputed ROOT
2. Performed a staged restore into a timestamped drill directory
3. Verified extracted content (file count + spot-check)

## Key Paths

| Item | Path |
|---|---|
| Backup Run (source) | \`$run_dir\` |
| Encrypted Archive | \`$run_dir/archive.tar.gz.age\` |
| Manifest | \`$run_dir/manifest.json\` |
| ROOT | \`$run_dir/ROOT.txt\` |
| Drill Target | \`$target\` |
| Extracted Files | \`$target/extract\` |

## Status Matrix

$(if [[ -f "$status" ]]; then
  echo '```json'
  cat "$status"
  echo '```'
else
  echo "_Missing status_matrix.json — run 90_verify.sh first._"
fi)

## EU Compliance Declaration

| Aspect | Value |
|---|---|
| Data Residency | EU (Ireland - Dublin) |
| Jurisdiction | Irish Law |
| Recovery Drills | Local-only by default |
| Encryption | age |

---

## Next Steps
1. Run drills on a **second machine**
2. Define a service-specific production restore (Portal, Node gateway, etc.)
3. Keep at least one **offline** copy of age identity keys
