The five conditions

• ✓ Scientists agreed the harm would be uncontainable Open letters from researchers across the field warned that mirror-life organisms could not be defended against by any known biological mechanism.
• ✓ No commercial capital had flowed in Mirror-life had stayed in academic labs. There were no investors, no startups, and no pipeline of paying customers waiting for the technology to mature.
• ✓ The research community was small and well-coordinated Only a few dozen labs had the expertise. Everyone knew everyone, which made a coordinated voluntary pause achievable in a single document.
• ✓ No state had staked its position on the technology No major government had declared mirror-life a strategic priority. There was no race to be first, and so no national-security argument against pausing.
• ✓ The pioneers were willing to abandon their own work The very researchers who had spent years building toward mirror-life publicly walked away. Their credibility carried the field with them.
