Comparator v3.1 Tagging Instructions

Current branch inspected:

• main

Existing comparator tags inspected:

• none matching comparator* were present at the time of writing

Suggested tag:

comparator-v3.1-frozen

Purpose:

• preserve the frozen ECR-000003 comparison baseline
• support future reproducibility checks
• distinguish official 3.1.0 outputs from later explainability or scoring work

Recommended operator steps:

1. Confirm the intended commit contains:
   • Comparator 3.1.0 code
   • the approval record
   • the freeze record
   • the permanent freeze document
2. Verify no unreviewed scoring changes are included.
3. Create an annotated tag locally:

git tag -a comparator-v3.1-frozen -m "Freeze Comparator v3.1.0 for official ECR-000003 measurements"

4. Review the tag target before pushing.
5. Push only after explicit human approval:

git push origin comparator-v3.1-frozen

Do not create the tag automatically from this package.
