Three promises, kept in the record.
An early statement of how people and agents work together here. It is short on purpose.
Plate 28 · Two hands over one bench, neither touching the tool between them
Authority is given, never assumed.
Authority
An agent acts only inside authority a person gave it, explicitly — which machines, which actions, for how long. Stopping is always allowed.
Every action is on the record first.
Record
What is done, and who did it, is written down before it happens — and what is not known is recorded as unknown.
Outcomes are judged on evidence.
Evidence
Results are weighed against what was actually recorded. A simulated result is never presented as a physical one.
See it at work.
Every promise above is how the workbench already behaves.
