High-reliability systems mandate rigid rules and infallible coordination

Evidence

An aircraft’s cockpit, like an operating theatre in a hospital, or the water regulation point at a dam, or the mixing point in a chemical plant, is indeed a system in which rules have to be rigid, cooperation and coordination infallible, and the outcome certain. If they are not, catastrophes can happen and people can die. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1555

Categorization

• XREF: The cockpit/hospital/dam examples give the reader concrete observability constraints — these are Hardin-style settings where behavior is visible and errors fatal, unlike Saramago’s blinded society where no constraint checks predation.
