"Safety is not a component, but an emergent property of the system.
Safety cannot be bolted on. If it is an emergent property, it lives in interactions: what gets reviewed, what gets tested, what gets deployed by default, and what gets escalated early. A safe system is one that makes unsafe actions hard.
Teams treat safety as a component when they think a tool or a gate makes the system safe. Incentives, handoffs, and exceptions decide the real safety level. The exception path is where the system tells the truth. When incentives reward speed and punish escalation, the system becomes unsafe even with good tools.
Re-state a standard that describes the interaction you require, and make the exception path explicit. Silent exceptions are how safety disappears while everyone believes it is still present. Keep the exception narrow and assign the decision.
