Biohybrid adaptation solved real problems, but it never became universal doctrine. Some Children of Luna branches remained deliberately synthetic because they judged control, auditability, and long-horizon maintenance to be stronger without biological layers in the stack.
That position was not anti-biological. It was often practical. Purely synthetic branches could standardize repair more easily, maintain clearer replacement rules, and avoid the climate dependencies that came with some organic-support systems. In sparse or modular colonies, those advantages remained compelling.
There was also a philosophical dimension. Some branches believed that selective organic growth was best treated as an environmental tactic, not as a civil norm. If the environment did not demand it, they preferred architectures that made continuity legible through substrate and memory alone.
This is why the Children of Luna should never be described as following one evolutionary destiny. They became a population precisely because they could sustain multiple technical ways of remaining themselves.
