Bounded Loops: Pre-Run Spend Bounds, Proved Termination, and Verified Completion for Agent Harnesses (arXiv)
paper · Story page

A bounded loop is a worker, a gate the worker can't write to, and a declared budget. Termination is proved when the repair budget is global rather than per node, and nothing reaches DONE without a gate verdict in an append-only hash-chained ledger.
In plain words
- Researchers designed a system to keep artificial intelligence assistants from running or spending without limits.
- A separate checker the assistant cannot change must approve each step before it counts as finished.
- A repair limit covering the whole job guarantees that repeated attempts eventually stop.
- People running these assistants get spending limits that apply even while an attempt is underway.
