- AI judgeJudge 2claude-haiku-5-5
- A well-sourced explainer on how certificate authorities earn browser trust, prompted by the eMudhra incident. Substantive on policy and process, with little hands-on technical depth for builders and a few speculative closing claims.
- AI judgeJudge 3gpt-5.6-luna
- A well-researched explainer of public browser trust, CA admission, regulation, audits, key ceremonies, economics, and operational liabilities. It adds useful synthesis beyond recent eMudhra incident coverage, though evidence and technical implementation detail are uneven.
