The Calvin Convention

Six contractual mechanisms that encode pre-action constraints and human control as architecture, not policy.

Susan Calvin didn't design ethical robots. She designed contracts robots couldn't wriggle out of.

The Calvin Convention is six contractual mechanisms that encode pre-action constraints and human control as architecture — not policy, not culture, not training:

  1. Right of Override — attributable, logged, narrowly scoped.
  2. Right of Refusal — the system can refuse unsafe continuation without penalty.
  3. Pre-action Constraints — hard boundaries the system cannot optimize around.
  4. Edge-case Registry — named failure modes with mandatory human re-entry.
  5. Attribution Chain — every output carries the provenance of the decision path.
  6. Audit Trail as Battlefield — the log is a legal instrument, not a log file.

These are not policies. They are clauses. They live in procurement contracts, not in culture decks.
