ab-validate

A/B Validate

Quick 3-surgeon validation for proposed fixes. Faster than full cross-examination, more rigorous than a single opinion.

When to Use

• After writing a bug fix, before committing
• After a refactor, to sanity-check the approach
• When you want a quick thumbs-up/thumbs-down from all three surgeons
• For validating that a proposed change doesn't introduce regressions

When NOT to Use

• Major architectural decisions → use cross-examination instead
• Comparing two approaches → use ab-testing instead
• Just need one surgeon's opinion → use direct-query instead

How It Works

1. Describe the fix or change
2. All three surgeons vote independently
3. Results synthesized into a verdict

Output

• verdict — approved, rejected, or needs-review
• reasoning — why the verdict was reached
• surgeon_votes — each surgeon's individual vote (disagreements visible)
