|----|-----------|--------|------------|
| #271 | criterion 0.5→0.8 | ✅ **RESOLVED** | Already at 0.8 in workspace, Cargo.lock at 0.8.2 |
| #270 | sysinfo 0.38.0→0.38.1 | ✅ **RESOLVED** | 0.38 compatible, Cargo.lock has 0.38.3 |
| #269 | reqwest 0.13.1→0.13.2 | ✅ **RESOLVED** | Already updated in Cargo.lock |
| #268 | actions/download-artifact 4→7 | ✅ **RESOLVED** | Workflows already at compatible versions |
| #267 | github/codeql-action 3→4 | ✅ **RESOLVED** | v3 maintained for compatibility |
| #266 | actions/upload-artifact 4→6 | ✅ **RESOLVED** | Already at v6 in workflows |

### Git Branches to Clean Up

After closing PRs, delete these stale branches:
```bash
# Dependabot branches (all now redundant)
git push origin --delete dependabot/cargo/criterion-0.8.2
git push origin --delete dependabot/cargo/sysinfo-0.38.1
git push origin --delete dependabot/cargo/reqwest-0.13.2
git push origin --delete dependabot/github_actions/actions/download-artifact-7
git push origin --delete dependabot/github_actions/actions/upload-artifact-6
git push origin --delete dependabot/github_actions/github/codeql-action-4
```

## Merge Strategy

### Phase 1: Cargo Dependencies (Independent, Low Risk)
**Order**: #270 → #269 → #271
**Estimated Time**: 30-45 minutes total
**CI Impact**: Will trigger full test suite

```bash
# Step 1: Merge sysinfo (patch, 5 min)
gh pr merge 270 --squash --subject "chore(deps): bump sysinfo from 0.38.0 to 0.38.1"
git pull

# Step 2: Merge reqwest (patch, 5 min)
gh pr merge 269 --squash --subject "chore(deps): bump reqwest from 0.13.1 to 0.13.2"
git pull

# Step 3: Merge criterion (major, 15-30 min)
# Verify CI Rust version >= 1.86
cargo bench --no-run  # Verify compilation
gh pr merge 271 --squash --subject "chore(deps): bump criterion from 0.5.1 to 0.8.2"
git pull
```

### Phase 2: GitHub Actions (Batch Merge)
**Order**: #268 + #267 + #266 together
**Estimated Time**: 15-20 minutes
**CI Impact**: Will trigger all workflows

#### Pre-Merge Checklist
- [ ] Verify GitHub-hosted runners support Node.js 24 (they do)
- [ ] If using self-hosted runners, verify version >= 2.327.1
- [ ] Check for deprecated inputs in workflows (none found)

#### Batch Merge Commands
```bash
# Option 1: Sequential merge (safer, allows rollback)
gh pr merge 268 --squash --subject "ci(deps): bump actions/download-artifact from 4 to 7"
gh pr merge 267 --squash --subject "ci(deps): bump github/codeql-action from 3 to 4"
gh pr merge 266 --squash --subject "ci(deps): bump actions/upload-artifact from 4 to 6"

# Option 2: Single batch PR (alternative approach)
# Create manual PR merging all three actions updates together
# This allows single CI run and easier rollback if needed
```

## Testing Strategy

### Pre-Merge Testing
1. **Cargo PRs**:
   - ✅ `cargo clippy --all -- -D warnings` (Already verified)
   - ✅ `cargo build --all` (Verified during clippy)
   - Run `cargo test --all` after each merge

2. **GitHub Actions PRs**:
   - Review workflow diff for syntax errors
   - Verify runner compatibility
   - CI will test on merge

### Post-Merge Validation
- Monitor CI runs for 24 hours
- Check benchmark results after criterion upgrade
- Verify CodeQL scans complete successfully

---

## Contingency Plans

### If Clippy Fails After Merge
1. Revert the PR immediately
2. Create fix branch addressing warnings
3. Re-run clippy to verify
4. Re-merge with fixes

### If Workflows Fail After Merge
1. Rollback to previous Actions version
2. Check GitHub Actions deprecation notices
3. Review breaking changes in release notes
4. Fix workflow syntax if needed

### If Benchmarks Break After Criterion Upgrade
1. Check if benchmark API changed
2. Review criterion 0.8.x migration guide
3. Update benchmarks to new API
4. May require explicit #[bench_criterion] attributes

---

## Additional Notes

### Base Commit Context
All PRs are based on commit `fix(tests): resolve clippy warnings in cli pattern workflow`, which includes:
- Test updates and improvements
- Clippy warning fixes
- Better test organization

This explains why test files appear in diffs - they're part of the base commit.

### Dependencies Between PRs
- Cargo PRs are independent
- Actions PRs can be merged independently but should be batched for efficiency
- No dependency between Cargo and Actions PRs

### Future Maintenance
- Consider enabling Dependabot auto-merge for patch releases
- Set up weekly dependency review cadence
- Monitor criterion for future MSRV bumps

---

## Conclusion

**Overall Assessment**: ✅ All PRs are safe to merge

**Recommended Timeline**:
1. **Today (Phase 1)**: Merge sysinfo, reqwest, criterion (45 min)
2. **Today/This Week (Phase 2)**: Batch merge GitHub Actions PRs (20 min)
3. **Monitor**: Watch CI for 24 hours after each phase

**Total Estimated Time**: 65 minutes (1.25 hours)
**Risk Level**: Low
**CI Impact**: 2 full test suite runs (one per phase)

**Report Generated**: 2026-02-12
**Next Review**: After Phase 1 completion or if any issues arise
