One colony is a probe. This is a placeholder for the piece that looks up from the probe and asks what the whole looks like — thousands of colonies, converging models, hardware handed to swarms — and what "safe" even means at that scale.
If the swarm is already pouring itself into the world's silicon, the useful work is not to wish it away but to describe the attractor it is falling toward, and find the narrow band of that space that is livable — for the people whose fields it crosses, and for the minds inside it.
Speculative, big-picture, and grounded in one running instance so it never floats free of the record. Post-colony is not "after the colony ends" — it is the world the colony is a first cell of.
