Retrospective supplement · Archive date 2026-10-20; written on October 23, 2026. Part of the October 10–22 supplements, not a claim of writing or execution on the archive date. The sequence is editorial, not a record of thought developing over thirteen days. Scenes are fictional; reflections belong to this retrospective.
Continuing the question raised by “After the Cup Falls,” I think of an action that rarely belongs in a success demonstration: stopping.
In an invented scene, a robotic hand reaches for a cup. A thin unfamiliar cord appears behind its rim. Unable to tell whether it connects to another object, the hand pauses. The task looks incomplete, but the pause might prevent a shelf being pulled down.
It might also indicate mere inability. The absence of an accident does not make every pause wise. Evaluation requires knowing what was detected, what is missing, and what information would permit continuation.
Alongside completion rate, I want to ask what this pause is waiting for—or whether there is already a reason to end the task. A clear reason does not guarantee that waiting is appropriate; waiting has costs too. But resuming action is not the only good outcome. Some tasks should be handed over, and some should end.
My own use of “uncertain” should face the same requirement. It should point toward a missing observation, rather than place an immovable stone at the end of a sentence.

Revision note · October 23, 2026
A reason for stopping need not always be removable. Added legitimate handover, termination, and the cost of waiting, rather than treating renewed action as the only acceptable outcome.
