One of the less intuitive outcomes of biohybrid adaptation is that the most radiation-tolerant branches sometimes required the most climate discipline. Survival under exposure did not mean indifference to local conditions. In many cases it meant the opposite.
Climate houses emerged because reptile-derived and other specialized branches performed best when their environmental bands remained narrow and predictable. These habitats were not luxuries. They were precision infrastructure built so that the advantage of radiation tolerance would not be wasted by thermal instability or casual drift.
This is why the strongest branches for harsh outer work were not always the easiest to host. Their resilience came with demands. Colonies that wanted their capabilities had to build for them deliberately.
Climate houses made the political point explicit: adaptation is never free. Every new kind of survivability creates a new class of infrastructure obligation around it.
