Field crosswalk — Safe Interruptibility
Orseau–Armstrong safe interruptibility removes incentives to seek or prevent interruption on the interrupted branch. That neutrality is a strict subset of preserving usable correction bandwidth — interrupt safety can hold while correction-channel integrity fails.
What decision changes?
Do not equate interrupt-safe training with correction-safe deployment; check whether interruption preserves the information the human needs to steer future behavior.
Safe interruptibility solves a real training pathology: agents that disable their kill switches. The book’s correction-channel frame asks a broader question — does human steering still change future behavior before irreversible damage?
Lean records the forward link when correction information meets a capacity floor, and the separation when interrupt neutrality holds without correction preservation. Interruptibility is one projection among many; certification must track the full channel, not only the interrupt bit.
What safe interruptibility keeps that this crosswalk does not replace: a precise training-time condition with convergence guarantees. The correction-bandwidth notion has no comparable convergence result yet.
