Ground Control
Autonomous and long horizon agents: how they are run, fenced, verified, and what they do when nobody is watching.
Long-horizon agent tasks do not fail loudly. They fail green. On Orbyt, a live function wrote to a database table that did not exist, and every test passed the whole time. The horizon of an autonomous system is not model stamina.
One working session on Orbyt spawned 830 AI agents across seven days. At its busiest instant, nine were running. The interesting number is the gap, and what it tells you about where the real constraint in long horizon agent work has moved. It is not compute. It is verification.
A stack of Claude Code windows, one operator, a production SaaS. By day three the agents were never the constraint. I was.
Human-in-the-loop is not oversight when a person rubber-stamps 200 AI outputs an hour in four seconds each. That is an alibi, not a safeguard.
